Drum dryer is mainly used to dry block, powdered, paste type materials or materials with large water content. Cylinder dryer can dry materials like ore, sand, slag, coal, clay, sludge, coal slurry, hematite, copper, kaolin, slag, graphite, gypsum, ceramics, calcium carbonate, bauxite, tailings, etc.

The raw material is delivered smoothly through the cylinder, which improves the uniformity of material and increases its residence time. In addition, the efficiency of drum dryer has been improved a lot.

The material input into the drum dryer, it will contact the hot air flow and begin the drying process. The material is added from the higher end, the heat carrier enters from the lower end, countercurrent with the material. However, there is also a heat carrier and material that flow into the cylinder together. The wet material will directly or indirectly get the heat from the heat carrier and will be dryer finally. Then, the dried material will be output through the conveyor belt or screw conveyor.

The copy board equipped on the inner wall of the drum will constantly pick up the material, which will accelerate the heat exchange between hot gas and slag. Besides, a cleaning device is also provided to clean the resulting agglomerates and the material adhered to the wall in order to prevent clogging.

After the heat carrier passes through the dryer, it is generally required to collect the materials in the gas by a cyclone. If you want to further reduce the dust content of the exhaust gas, you should also discharge it after passing the bag filter or wet dust collector.

Weve built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECOs design team can design a rotary drum dryer for your application.

Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.

The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.

All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.

Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:

Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.

what is a rotary dryer and who uses it? - thompson dryers

what is a rotary dryer and who uses it? - thompson dryers

Most organic materials we want to actually use for something hold too much moisture in their natural state to do us any good. A rotary dryer has the distinguished roll of removing that unwanted water to turn the organic material into a useable, more desired product. Rotary drum dryers can be the most affordable, economic and versatile choice when considering a new or used industrial dryer. Rotary dryers are the workhorses of the drying industry because of their capacity, efficiency, and ability to adapt to new purposes.

Rotary drum dryers can be chosen for projects large and small. They come in all sizes to accommodate many products, quantities, and moisture content ranges. Although they can be much larger, a 14 diameter drums will accommodate many different needs and is the most practical for manufacture, transport, and installation. Depending on length, a 14 drum could produce 289,000 tons/year (263,000 tonnes/year) of 10%mcwb product from 50% mcwb product.

Rotary drum dryers can be designed to withstand extremely high temperatures and/or corrosive materials. A basic carbon steel drum is designed to withstand inlet temperatures from 1,000F 1,100F. With specialty materials, rotary drum dryers can handle much higher inlet temperatures. Stainless steel can be used in place of carbon steel if the product is known to be corrosive.

Rotary drum flighting is the primary material handling mechanism in a drum. Flighting can be designed to accommodate different flow characteristics of the materials to be dried. Some materials clump and potentially form balls which need to be broken up, while others flow easily and must be separated at a higher frequency per flight. Other pieces might be long and stringy and can easily get trapped. Different flighting designs can solve these, and other problems.

The flighting in a rotary drum dryer system can be changed to repurpose a used or existing dryer. A flighting designer can look at the flow characteristics of the material in question and determine what kind of flights are necessary, thereby converting the dryer to a new purpose at a fraction of the cost of buying a new dryer. Hopefully.

What products do best in a rotary drum dryer? Rotary drum dryers can dry many different types of products. Not only are they great for uniform solid particles, but they are the best solution for non-uniform solid particles. The number one factor in deciding what type of dryer to purchase is whether the material handling of the dryer matches what the product needs.

Products that have non-uniform particle sizes are perfect candidates for a rotary drum dryer, like the wood in the picture above. However, the flighting system would be different for the sample on the left than for the sample on the right than a sample with the two combined. It is important to know the characteristics of the infeed product to choose the best flighting design.

A rotary drum dryers greatest asset is its ability to accommodate a product that has multiple size particles and moisture contents by utilizing the right flighting package. As seen in the picture above the wood is in a variety of shapes and sizes. The flights can be designed to keep the larger pieces in the drum longer and allow the smaller pieces to flow more quickly. The right flighting package can help achieve uniform outfeed product moisture.

Who uses rotary drum dryers? We believe everyone should! Assuming you need to dry something. Almost everyone does use one at home a clothes dryer. But thats not exactly what were talking about. Rotary dryers are popular in the biomass and forestry industries, as well as the ethanol industry to dry WDGS. Thompson Dehydrating Co., Inc. made its start in the alfalfa drying industry. Sugar processing plants have used rotary dryers to dry bagasse. There are food and pharmaceutical companies that use rotary dryers. Ethanol producers arent the only ones that want to dry the by-product of alcohol production. There is a push for microbrewers to dry and repurpose their byproducts. An up-and-coming technology, torrefaction, is being made possible on an industrial scale by rotary dryers.

Conclusion Organic materials in a raw state typically have too much water to be further processed. Removing the excess water is the job of a dryer. And because of their capacity, efficiency, and all-around-good-looks, rotary drum dryers are the best choice. For projects large and small rotary dryers can handle them all!

Your dryer may be used primarily for drying clean clothing, but an unseen pen, crayon or some dirty clothes dried between washings can leave your dryer drum coated in various materials that can come off on clean clothes. Keep your dryer in good shape by cleaning the drum regularly to remove any of these stains.

To clean a dryer drum, open the panel surrounding the drum. Generally, either the top or front panel will come off, but check your user manual or the internet to make sure. Look for screws around the lint filter, since this is usually the spot to start. With the screws undone, the panel can be removed. Once the panel is removed and the drum is exposed, remove lint and lost items by hand or with a vacuum. To learn how to remove things such as ink, gum, or crayon from your dryer, keep reading!

In many countries of the world, the use of solar thermal systems in the agricultural area to conserve vegetables, fruits, coffee and other crops has shown to be practical, economical and the responsible approach environmentally. Solar heating systems to dry food and other crops can improve the quality of the product, while reducing wasted produce and traditional fuelsthus improving the quality of life, however the availability of good information is lacking in many of the countries where solar food processing systems are most needed. Solar food dryers are available in a range of size and design and are used for drying various food products. It is found that various types of driers are available to suit the needs of farmers. Therefore, selection of dryers for a particular application is largely a decision based on what is available and the types of dryers currently used widely. A comprehensive review of the various designs, details of construction and operational principles of the wide variety of practically realized designs of solar-energy drying systems reported previously is presented. A systematic approach for the classification of solar-energy dryers has been evolved. Two generic groups of solar-energy dryers can be identified, viz. passive or natural-circulation solar-energy dryers and active or forced-convection solar-energy dryers. Some very recent developments in solar drying technology are highlighted.

The major difference in dryers is how they're powered either by natural gas or electricity. Although you won't notice a difference in how thoroughly they dry, there are price differences. A gas dryer costs roughly $50-$100 more than its electric sibling. But a gas unit is generally less expensive to operate and will often pay back its higher cost in energy savings within the first year (depending on usage and utility rates). In addition, dryers that offer steam cycles to de-wrinkle and freshen garments have become popular in the last few years. If you select a dryer with this feature, it may be necessary to have access to a water hook-up, as well.

Because you won't find significant differences between brands with respect to the amount of energy they use, clothes dryers do not carry the yellow Energy Guide labels nor are they a part of the Energy Star program.

Full-size dryers range in price from about $350 for a bare-bones model to $1,000 and up. Most manufacturers in the $350-$450 price range offer white exteriors, mechanical controls and two to three temperature settings (low, medium, and high). You will also find timed dry, a cycle that lets you control the length of drying time (generally to 80 minutes) and air dry (no-heat settings). The drum size may also be smaller than that found on more expensive models.

Features multiply as you climb the price ladder. Many dryers have stainless-steel drums and extended tumbling cycles, which keep clothes tumbling without heat if they aren't immediately unloaded when a cycle ends.

For $600 and up, dryer manufacturers offer push-button controls, three or more temperature choices, adjustable end-of-cycle signals, cycle-time displays on the control panel, and drying racks. Many higher-end models come with drum lights, making it easy to spot those inevitable stray socks hiding in the back of the drum, along with specialty cycles for bedding, delicates, and active wear, steam and antibacterial cycles, LCD screens, control panel locks, speed dry cycles, high-fashion colors, and more.

How often do you use your dryer and what type of clothes do you dry weekly? If you have a family of four or more and regularly tackle jeans, sneakers, and heavy work clothes, you may prefer a large, heavy-duty dryer and one that offers a long warranty. If your wash load contains a wide variety of fabrics and garments, look for a dryer with the specialty cycles to give these items the care they require.

Where is your dryer located? If your clothes dryer will be installed in a dimly lit basement, look for a console that includes indicator lights and has large, legible type or a bright digital readout. Always consider how your dryer will be vented to the outside. Make sure the model you select can be vented in the direction your installation requires.

Do you often juggle wash with other chores? If you're a multitasker on washday, check out clothes dryers with moisture sensors in the drum. These sensors detect the moisture remaining in the load and automatically stop the cycle when your clothes are dry reducing wear and tear on the garments. Extended tumbling is another option worth shopping for. It lets you dial up to a three-hour unheated, intermittent tumbling period to keep wrinkles from setting in until you unload the dryer. Dryers offering steam refresh cycles can freshen and dewrinkle garments that you have left in the dryer with a 15- or 20-minute steam treatment.

How long do you plan to keep your clothes dryer? If you're buying the appliance for a temporary home you plan to sell in a few years, you may not want to spend a lot if you don't plan to take it with you.

If you tend to pop clothes into the dryer in the morning before work (when you're time-pressed), the "favorite" cycle lets you quickly set your most-used dryer cycles with one touch. Another notable dryer feature is reverse tumbling. This is where the drum periodically reverses direction during the cycle to better keep garments and large items, like bedding, tangle-free. Any dryers that offer antibacterial or sanitizing cycles should be NSF-certified. This third-party certification gives you the assurance that the cycle will kill 99.9% of germs, as expected. For safety, we also recommend control panels that offer locks to keep children from accidentally starting the appliance or changing the cycle.

And some models have easy-to-read digital consoles, removable drying racks (for items such as sneakers and stuffed toys that can be harmed by tumbling) and hamper-style doors (which reduce the chance of clean clothes dropping on a soiled floor).

Electronic controls are spiffier looking and allow certain conveniences, but they can be more expensive to service because of their circuitry. Dial controls are less expensive than electronic ones but can be difficult for some users to turn. When you're shopping for a dryer, be sure to give all the controls a test run for comfort and ease of use,

Before buying your clothes dryer, consider the logistics. When will someone be home to accept delivery of your clothes dryer? Do you need your old unit hauled away or does your town allow curbside pickup of appliances? Will the new dryer fit through doorways and up or down stairs easily when delivered?

You generally get a one-year parts-and-labor warranty included in the sticker price. Limited warranties are also available for additional years or for parts like the motor, drum and electronic controls from certain brands.

A conveyor-belt dryer was developed using a combined infrared and hot air heating system that can be used in the drying of fruits and vegetables. The drying system having two chambers was fitted with infrared radiation heaters and through-flow hot air was provided from a convective heating system. The system was designed to operate under either infrared radiation and cold air (IR-CA) settings of 2000W/m2 with forced ambient air at 30C and air flow of 0.6m/s or combined infrared and hot air convection (IR-HA) dryer setting with infrared intensity set at 2000W/m2 and hot at 60C being blown through the dryer at a velocity of 0.6m/s or hot air convection (HA) at an air temperature of 60C and air flow velocity 0.6m/s but without infrared heating. Apple slices dried under the different dryer settings were evaluated for quality and energy requirements. It was found that drying of apple (Golden Delicious) slices took place in the falling rate drying period and no constant rate period of drying was observed under any of the test conditions. The IR-HA setting was 57.5 and 39.1% faster than IR-CA and HA setting, respectively. Specific energy consumption was lower and thermal efficiency was higher for the IR-HA setting when compared to both IR-CA and HA settings. The rehydration ratio, shrinkage and colour properties of apples dried under IR-HA conditions were better than for either IR-CA or HA.
