Spices are an integral part of the Indian diet since centuries and they are used in vegetarian and non-vegetarian food and snack preparations. They help enhance the taste of food. Some specialty spices are grown at specific locations but turmeric, chilly etc. are grown in many parts of the country and their consumption is also very high as compared to some other spices. Thus, they are fast moving items, consumed in all households and therefore the market is very scattered.

To start with, ungrounded spices are cleaned mechanical to remove impurities and then washed. After drying them, they are pulverized in a grinder to convert them in powder form. Turmeric being solid by nature, it is taken to disintegrator and then pulverized or with help of modern screen less impact pulverizer obtain turmeric powder in single grinding.. Then spices in powder form are passed through sieves to obtain uniform mesh size. Finally, packing is done in polythene bags and bags are sealed. Process loss is in the range of 5% to 7%.

After cleaning the spices whole spices like cumin, coriander etc.. must be roasted with salt or other ingredients for increasing fragrance, aroma and self life. For that jas enterprises has developed rotary spice roaster machine which is operated by electric for motion and gas for heat. please contact to us for more details.

process flow chart - an overview | sciencedirect topics

The process flow chart is one of the most important outputs from process design and development. This is a complete flow chart of the process flow and can be used to identify sources of variation using cause and effect charts) for the complete process. A process flow chart means that the team can look at the complete process rather than on the individual steps in the process and this is invaluable when completing the Process FMEA (see Section 10.2) and the Control Plan (see Section 10.3).

The flow process chart was originally introduced by Frank Gilbreth in 1921 as a structured method for documenting process flow, in his presentation Process Charts, First Steps in Finding the One Best Way to Do Work. Gilbreths tools quickly found their way into industrial engineering curricula (Wikipedia). With the advancement of information technology, the flow charts have been applied extensively using most of the symbols as illustrated.

Flow chart is also known as process flow diagram or chart, or system flow diagram or simply flow chart, a term used by industrial engineers, depending upon the application basically a manufacturing system. It is used primarily in process engineering and the chemical industry where the complex relationship between major components and how the material flows through various stages and components is depicted to provide an easy comprehension of the user. This generally is a combination of outline process chart and the flow diagram, where each operation is represented by the appropriate shape of the equipment as illustrated in Fig. 20.11. This gives a visual picture of the equipment, as well as the operation sequence. Sometimes the equipment is represented by functional blocks. Even in computer programming, flow charts are used to represent a series of decisions and the corresponding actions taken. A typical such flow diagram for a nuclear power plant is illustrated in Fig. 20.12.

Fig. 20.12. Flow chart of a nuclear power plant. A, B & C: Primary, secondary and cooling water circuits, D: Core reactor, E: Control Rods, F: PORV, G: Primary booster pump (EIW), H: Steam generator (boiler), I: TurbineGenerator, J: Heat Exchanger, K: Demineralizer, L: Condensate tank, M: Secondary water booster pump, N: Cooling Tower.

It may be noted that in industrial engineering and work study, nomenclatures like flow diagrams, operation flow charts, etc. are used with slightly different applications. These charts are explained in the appendix so that we can distinguish clearly between the nomenclature used in TQM books and those used in Industrial Engineering books.

Figure 1.14 shows a generalized process flow chart for a typical refinery. Table 1.5 provides a chronological summary of the refining technologies and years in which they were introduced commercially. Major sections of refineris include three major groups:

The first US refinery was commissioned in 1861. It produced kerosene by means of atmospheric distillation. By-products included tar and naphtha. It was soon discovered that high-quality lubricating oils could be produced by distilling petroleum under a vacuum. However, for the next 30 years kerosene was the product of demand in the market. The invention of the electric light decreased the demand for kerosene, but the invention of the internal combustion engine created a demand for diesel fuel and gasoline (naphtha).

World War I created the impetus for mass production whereby the number of gasoline-powered vehicles increased dramatically. Subsequently, the demand for gasoline grew accordingly. However, distillation processes produced only a certain amount of gasoline from crude oil.

In 1913, the thermal cracking process was developed, which subjected heavy fuels to both pressure and intense heat, physically breaking the large molecules into smaller ones to produce additional gasoline and distillate fuels. Visbreaking

Higher-compression gasoline engines required higher-octane gasoline with better antiknock characteristics. The introduction of catalytic cracking and polymerization processes in the mid to late 1930s met the demand by providing improved gasoline yields and higher octane numbers. Alkylation is another catalytic process that was developed in the early 1940s, to produce more high-octane aviation gasoline and petrochemical feedstock for explosives and synthetic rubber.

Catalytic isomerization was developed to convert hydrocarbons to produce increased quantities of alkylation feedstock. Improved catalysts and process methods such as hydrocracking and reforming were developed throughout the 1960s to increase gasoline yields and improve antiknock characteristics. These catalytic processes also produced hydrocarbon molecules with a double bond (alkenes) and formed the basis of the modern petrochemical industry.

Various treatment methods have always been used to remove non-hydrocarbons, impurities, and other constituents that adversely affect the properties of finished products or reduce the efficiency of the conversion processes. Treating involves chemical reaction and/or physical separation. Typical examples of treating are chemical sweetening, acid treating, clay contacting, caustic washing, hydrotreating, drying, solvent extraction, and solvent dewaxing. Sweetening compounds and acids desulfurize crude oil before processing and treat products during and after processing. Following the Second World War, various reforming processes were developed to improve gasoline quality and yield and to produce higher-quality products. Some of these involved the use of catalysts and/or hydrogen to change molecules and remove sulfur. A number of the more commonly used treating and reforming processes are described later.

Other important refining operations include: light-ends recovery; sour-water stripping; solid waste and wastewater treatment; process-water treatment and cooling; storage and handling; product movement; hydrogen production; acid and tail-gas treatment; and sulfur recovery.

Auxiliary operations and facilities include: steam and power generation; process and fire water systems; flares and relief systems; furnaces and heaters; pumps and valves; supply of steam, air, nitrogen, and other plant gases; alarms and sensors; noise and pollution controls; sampling, testing, and inspecting; and laboratory, control room, maintenance, and administrative facilities.

Figure 60 provides a generic demonstration process flow chart. It is similar to the test task described above. A demonstration, like a test, can take place as a single step or consist of a series of steps, either repeating the same step in a probabilistic data collection sequence or moving on to a different purpose. It is possible to damage or overstress the product in a demonstration, so provisions may have to be provided for refurbishment to support continuing qualification work. Disposal of residual materials may also be necessary subsequent to or during a demonstration.

Flow process chart sets out the sequence of the flow of a product or an equipment or a man, by recording all the events under review using appropriate process symbols. These flow process charts can either be material type or equipment type or man type, depending whether the subject being charted is the material, equipment or man.

Equipment type, wherein the movement of certain equipment like welding equipment, portable drills, cranes, fork lift trucks and air compressors, that are taken from work place to workspace on a regular basis. This chart would be useful if this equipment causes bottlenecks or excessive waiting time at the workplace that needs it. For example, the bus in Fig. 7.7 needs to be gas welded at 4 places A to D, and only one gas welding equipment is available. The flow process chart for this can be drawn as per Fig. 7.8.

The work sequence or elements are not exactly identical, but vary from cycle to cycle. This variation may be due to the operator's practices like cleaning an equipment or may be due to the inherent nature of the work like the maintenance operations or like the powdering of the hardened fertilizer in bulk storage.

The work is cyclic but includes several sub-cycles performed with different frequencies. A typical example is in packing operations, where small automobile components are packed in individual cartons, then 10 of them are packed in a larger carton and 4 or 6 of the larger cartons packed in wooden boxes, all these forming one cycle. In this case it is essential that to indicate the frequency of each element and the sub-cycle.

The format used is generally common, whatever the type of chart, as illustrated by Fig. 7.6, bearing in the heading, man/material/equipment. While filling up the form, the two words not needed would be canceled. In some cases, a simpler form of a flow process chart is drawn, as in Fig. 7.8, though not much preferred. Nevertheless, this can be used for an initial recording, which may later be transferred to the chart of the former format.

The answer to (b)is a little easier. It simply requires you to say you will check the Risk Analysis periodically, and, as I said earlier, if you have a risk analysis that is more than 2years old you are not doing very well. A simple statement such as:

Data is proactively sought from users regarding products in the post production stage as per the requirements of ISO 13485:2016. This information is fed into the Company's monitoring and analysis process and the risk analysis is revised and reviewed according to the ISO 14971:2012 standard.

Page 6: This is a blank pro-forma for the risk management folder title page (Part 1 of the technical file's risk management file described in a later chapter, or of the company's risk register as described in the next section). This pro-forma is, basically, laid down by ISO14971 and should look like Fig.9.4.

Note the last sentence the person signing off the risk analysis MUST BE QUALIFIED TO DO SO: hence we are looking for staff with formal, professional qualifications such as Chartered Engineers, Licensed Engineers, Professional Risk Assessors, persons with an ISO14971 training certificate, persons with postgraduate qualifications in medical devices design. The person signing it off cannot be the managing director or CEO just because of their position they have to be qualified to do so. If you wish to avoid this sentence you can add another line to signature: qualifications".

Please do not forget this is a controlled document, so the whole document requires a title such as Risk Management Procedure, it needs approval, a version number, and a date of approval yep document control!

It does not hurt to keep this document brief so that EVERYONE in the company has one on their desk or workstation! Making sure everyone is trained and updated on the company's risk management procedure(s) is essential!

After selecting the job to be studied, the next set is to record all the facts relating to the existing method. The success of the whole procedure depends on the accuracy with which the facts are recorded, because they will provide the basis of both the critical examination and the development of the improved method. When methods are studied, they cannot be viewed in isolation because each operation is affected by the operation before it and the one after it.2

The useful way of recording is to write them down. Unfortunately, this method is not suited to recording the complicated processes, which are so common to modern industry. This is particularly so when an exact record is required of every minute detail of a process or operation.

To overcome this difficulty other techniques or tools of recording have been developed, so that detained information may be recorded precisely and at the same time in standard form, in order that it may be readily understood by all method study persons.

Transaction and transformation can actually work together on a single problem. For example, consider the process flow chart in Figure 4.8 where transactional and transformational leadership feed each other to create and sustain improvement.

The first step is identifying an opportunity to improve. This can come from transactional leadership such as measurements in the factory that show an increasing quality problem (1a). In this case, a process in the organization is constructed to detect a problem. Working within the system normally identifies the issue; discipline, process, and attention to detail will usually bring success.

But, you can also identify an opportunity through transformational leadership (1b). These are the places you find by looking outside the process. Are design reviews accomplishing what projects really need them to? Are people confused about what the goals of the projects are? Your intuition fed by your connection to your team guides you in finding these types of opportunities.

In the next step (2), you must decide whether this problem can be fixed within the system or not. Do you need to better follow the process of how you qualify suppliers to prevent a quality problem from returning? Thats transactional leadership (3). Or do you need to sit down with a team member to better understand what personal growth they are looking for in the project so you can help them find tasks that will be more satisfying. Thats transformational leadership (4). For those solved with transformation, you need to decide if this type of improvement must be sustained (5)if so, youll need to improve transactional leadership too. For the example of the team member above, perhaps you need to create a career growth plan and then schedule a meeting every 2 or 3months to review progress (3); thats using transaction to sustain transformation. Or you may decide that one conversation and a few follow-up actions are sufficient to resolve this problem (6). Transaction usually adds an enduring burden of measurement and review, so apply it only where its needed.

So, transactional and transformational leadership work together. Each set of skills helps identify different areas to improve; each gives different ways to bring the improvement about. Yesterdays transformation can be sustained with todays transaction. Todays transaction makes the team more efficient, freeing up time to work in new areas with future transformation.

In Chapter 7 we have studied the various recording charts that should be drawn for analysis and development. The same charts like outline process charts, flow process charts, process charts and flow diagrams, whichever were drawn for, the existing method should now be drawn and charted for the proposed operation procedure also. Each and every operation shall be detailed with reference to the procedure, tools, jigs, inspection gauges, etc. so that the shop personnel can perform the operation exactly in the way you set it without any wrong interpretation.

Apart from the above charts and graphic presentation, Standard operation procedures (SOP) as further detailed in paragraph 9.2 shall be written down. This also can be called Operative Instruction Sheet or Work Instructions. While procedures provide a general view of the higher-level steps, Work Instructions are significantly more detailed.

Whatever may the terminology, the International Quality Standard ISO 9001 essentially requires the determination of processes (documented as standard operating procedures) used in any manufacturing process that could affect the quality of the product.

Some of the earliest graphical techniques used in layout design were schematic representations of the manufacturing operations required on each part. Examples of these techniques are operations process charts, flow process charts, and assembly charts (Apple, 1977). The designer used the schematic model to establish the logical relationships among the operations, and these were, in turn, used to establish a spatial arrangement of the equipment that allowed for a smooth flow of material. However, as the number of different parts increased, these techniques provided little benefit in aiding the designer.

A Process Flow Chart is a pictorial representation of a process, using a variety of symbols connected by lines and arrows. A Process Flow Chart provides a clear picture of each stage of a process, the interrelationship between stages of the process, and the direction of the process flow.

A Process Flow Chart is a pictorial representation of a process, using a variety of symbols connected by lines and arrows. A Process Flow Chart provides a clear picture of each stage of a process, the interrelationship between stages of the process, and the direction of the process flow.

A rectangle is generally used to identify a process activity, or an action step, in the overall process. Activities such as machining a thread, grinding a surface, and assembling components are examples of activities that could be represented by the rectangle.

The diamond is used to indicate a decision required in the process. The information contained in the diamond generally takes the form of a question. Decisions such as make or buy, cast or machine, and ship or stock are represented by the diamond. Probably the most common use of the diamond symbol is in quality assurance. If a part meets certain quality criteria, then a subsequent process occurs. If the part does not meet these criteria, then an alternate process occurs. These two alternate processes would be shown as branches running from different points on the diamond.

This symbol is used to represent delays in the process. If a part must be placed in a temporary storage area, awaiting delivery to a secondary operation, this delay would be described by this symbol. It is helpful to see graphical representations of delays in a process, as these are the first areas that should be addressed when trying to streamline the process. In a Process Flow Chart, the fewer the number of delay symbols, the more efficient the process.

The inverted triangle symbol designates a storage activity. If raw material is ordered and brought to a stockroom, this symbol is used. Likewise, if a sub-assembly is taken to the stock room at some time during the overall manufacturing process, then this symbol could represent this activity. The inverted triangle is another symbol that represents non value-added activity, so it should be the focus of any streamlining efforts.

There are other symbols that may be incorporated in Process Flow Charts. A circle serves as a Go To symbol and is used when your flowchart gets too big for one sheet of paper (for example, Go to Page 2), or when your flowchart gets complicated and you want to avoid lines that cross each other. A square may be used to denote a specific inspection process. However, the four symbols shown above are the most important and can be used to complete almost any Process Flow Chart.

gypsum mining | processing equipment | flow chart | cases - jxsc

Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly associated with rock salt and sulfur deposits. It is processed and used as prefabricated wallboard or as industrial or building plaster, used in cement manufacture, agriculture and other uses.

Most of the worlds gypsum is produced by surface-mining operations. In the United States, gypsum is mined in about 19 states. The states producing the most gypsum are Oklahoma, Iowa, Nevada, Texas, and California. Together, these states account for about two-thirds of the United States annual production of gypsum. Over 30 million tons of gypsum is consumed in the United States annually. Canada, Mexico and Spain are other significant producers of raw gypsum. In all, more than 90 countries produce gypsum. In most open pit gypsum operations, benches are drilled and blasted using ammonium nitrate as the explosive. Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute. Sometimes the drill holes become wet, which can cause problems with the ammonium nitrate. In these cases the ammonium nitrate is bagged in plastic bags before being lowered into the blast hole. Mines use approximately 1 kg of explosives for each ton of gypsum they blast.

The most significant use for gypsum is for wallboard and plaster products. All modern homes in North America and other developed countries use a great deal of wallboard for interior walls. The United States is the worlds leading consumer of wallboard at over 30 billion square feet per year. Some gypsum is used to make Portland cement, and some is used in agricultural applications. A small amount of very pure gypsum is used in glass making and other specialized industrial applications.

Gypsum processing equipment differs significantly in scale and level of technology. some plants produce one or two tonnes per day using low-cost manual technologies, some other plants of a thousand tonnes per day that are highly mechanized and capable of producing different types and grades of gypsum plaster or plaster boards.
