Spray drying process is the widest used in the liquid forming process and in drying industry. The drying technology is most suitable for powder, particle products from materials, such as,solution, emulsion, SC and pumpable paste states material. For this reason, when the particle size and distribution of the final product, their residual water contents, the stacking density and particle shape must meet the precision standard, spray drying process is one of the most desired processes.
After filtering and heating, the air enters into air distributor on top of the Drying Equipment. The hot air enters into the drying tower spiral form and uniformly. By .passing through high-speed centrifugal atomizer on top of tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting with heating air, the material can be dried into final products. The final products will be discharged continuously from the bottom of drying tower and from cyclone separator. The waste gas will be discharged from exhaust fan.

3. the equipment is specially designed in the process of making, and it is convenient for the user to do antistatic treatment.
4. design an air hammer in the proper position of the tower body. regularly strikes the wall of the tower to reduce absorption.
Shrink the cone angle and increase the flow one cone surface.
5.Energy saving design
The main tower is designed as 3 layer structure. The insulation layer is designed between the jacket and the cover, which not only saves energy but also keep the temperature of work scene not too high. Improve the working environment, reduce the energy consumption of the factory's central air-conditioning.
Because the clearance needs in chemical production, especially for changing varieties The cleaning port is designed on the tower and the thicker pipeline, and the hand hole is designed for the easy aggregate part. The connection of each pipe is favorable for disassembly and installation. The whole silicone pad is used for cleaning and replacement.
The feed pipe is made of stainless steel pipe.
The material contact pipe is made of stainless steel pipe.
The wet dust remover is used in the tail gas treatment, especially designe demister to reduce the loss of water in the process of dust removal, you can use purified water as the circulating water if it is necessary to further reduce the cost of the product, the material return to the concentration process when it is set to a certain concentration, almost no loss of material.

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, Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price 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, Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price directly to the medium molecules converted into heat, because the Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price 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 Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price 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, Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price low temperature sterilization keep the nutrition and traditional flavor The Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price 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 Centrifugal microwave Atomizer Detergent Powder Spray Dryer Price 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%.
