Product Description

Rotary Dryer application:
Rotary drum Dryer Machine is widely used in building materials, metallurgy, chemical industry and cement industry, which is widely used to dry the stuff such as limestone, coal powder, slag and clay. The main features of the rotary dryer

1.dryer anti-overload, large capacity, low fuel consumption, low-cost drying;

2.the downstream drying, flue gas and the wet material into the dryer on the same side, can take advantage of the high temperature flue gas to get high evaporation, dryer outlet temperature, high thermal efficiency;

3.according to different material properties to change the operating parameters, so that the material to form a stable full cut fabric curtain in the dryer cylinder body, the quality of heat exchange more fully;

coal rotary dryer is developed based on the rotary dryer. It can be widely used in:

1. The coal industry: Coal slime, coal, flotation clean coal, mixed clean coal etc.

2. The construction industry: Blast furnace slag, clay, bentonite soil, lime stone, sand, quartz stone etc.

3. Ore processing industry: Various metal concentrates, slag, tailings etc.

4. Chemical industry: Non-drying heat sensitive materials

Coal slime rotary dryer is a kind of stable and reliable heating drying equipment, designed to dry materials of high moisture and strong stickiness, such as coal slurry, mud, gypsum, humid swell soil, electroplate mud and so on. The performance of coal slime dryer is better than tube rotary dryer and blade rotary dryer.

rotary dryer special features:

  • · Drying material with co-current or counter-current hot gas, the heating efficiency can be up to 95%.
  • · Coal Slime dryer should be operated under high temperature and low oxygen to avoid materials being burnt when drying.

rotary dryer main applicable areas:

  • 1. Coal industry: drying coal, coal slime, coal with flotation, drying mixed coal;
  • 2, Construction industry: drying cinder, blast furnace slag, clay, limestone, sand, quartz;
  • 3, Mining processing industry: drying metal concentrates, slag, tailings;
  • 4, Chemical industry: heat non-sensitive materials.

Jinan Joysun Machinery Co., Ltd. for thawing of meat products and seafood, the equipment has stable performance, reliable quality and short thawing time. It is an ideal defrosting equipment for high-tech meat products, made of stainless steel, conforming to food production standard. Welcome new and old customers to inquire. Our international business covers customers all over the world. We have competitive prices and are proud of our excellent after-sales service. The working attitude of the company and the continuous improvement of the innovation concept will lead Tuo Bo and you to step into the brilliant future hand in hand and create a better future.
Through continuous exploration and practice, the company has developed the advantages of low investment, high efficiency, low operation cost, high product quality and convenient control and operation. The microwave frequency thawing equipment with microwave frequency of 915MHz and output power of 20kw-200kw is above. For food processing enterprises such as chain fast food industry in China, food thawing is provided, and the improvement of food thawing technology in China is also renewed. The benefit is not only "farsightedness", but also at the foot of the eyes. According to experts, the traditional food thawing are based on heat conduction method, material surface temperature is higher than the internal temperature in the thawing process, inevitably there will be drop loss, which will increase the business loss. If merchants use microwave dryer, Rotary microwave Dryer for graphite powder dryer power, material temperature and transmission speed can be used to achieve adjustable linkage, and the overall heating process control advantages can greatly reduce material consumption and improve food utilization. In addition, as the microwave thawing only needs electricity, no need to consume a lot of water, in the low carbon era, this is not lost a recommended fashion trend.

microwave dryer is a new type of environmental protection drying method. When dry, Rotary microwave Dryer for graphite powder dryer directly to the medium molecules converted into heat, because the Rotary microwave Dryer for graphite powder dryer penetrating performance of heating medium and at the same time, no need to heat conduction, so the heating speed is very fast, the water content below 30% of the food, the drying speed can be shortened hundreds of times.


microwave dryer advantages of equipment

1, microwave dryer, short, fast

Conventional thermal sterilization is used to transmit heat from the surface of the food to the interior through heat conduction, convection, or radiation. It often takes a long time to get the germicidal temperature. The Rotary microwave Dryer for graphite powder dryer is the direct interaction between microwave energy and microorganisms such as food and bacteria. The interaction between heat effect and non thermal effect can achieve fast warming and bactericidal action, and the processing time is greatly reduced. The sterilization effect of various materials is usually 3-5 minutes.


2, Rotary microwave Dryer for graphite powder dryer low temperature sterilization keep the nutrition and traditional flavor The Rotary microwave Dryer for graphite powder dryer is through special heat and non thermal effect sterilization, compared with conventional thermal sterilization, it can get the desired disinfection effect at relatively low temperature and short time. Practice shows that the general sterilization temperature can reach the effect at 75-80 degrees centigrade. In addition, microwave dryer processed foods can retain more nutrients and color, aroma, taste, shape and other flavors, and have puffing effect. For example, the vitamin C retained in vegetables treated by conventional heat treatment is 46-50%, while that in microwave treatment is 60-90%, while that in conventional heating is 58%, while that in microwave heating is 84%.


3 microwave dryer and Rotary microwave Dryer for graphite powder dryer save energy Conventional thermal sterilization often has heat loss in the environment and equipment, and microwave is directly treated to food, so there is no extra heat loss. In addition, the conversion efficiency of the electric energy to the microwave energy is in the 70-80%, and the power is generally reduced to 30-50%.
