Product Description

Product DescriptionDW Series mesh-belt dryer is a special equipment researched and developed on the basis of traditional net belt dryer. It has stronger pertinency, practicability and high efficiency of energy. It is widely used for materials with high water contents and low drying temperature, such as dewatering vegetable, herbal medicine,etc.
The materials are uniformly put on the mesh-belt by the material charger. The mesh-belt takes 12-60 mesh stainless steel wire net and it is drawn and moved inside the dryer by a transmission device. The dryer is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged with a special moisture elimination blower. The waste gas is controlled through an adjusted valve. The hot air passes through the mesh-belt covered with the material from the top to the bottom or from bottom to the top and this will complete the heat and mass transfer process. This process will bring the material water away. The mesh-belt moves slowly, running speed can be freely adjusted according to the material temperature. The final products after the drying will fall into the material collector continuously. The top and low circulation units can be freely equipped according to the users’ demand. The unit number can be selected according to the demand.

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, onions microwave belt 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, onions microwave belt dryer directly to the medium molecules converted into heat, because the onions microwave belt 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 onions microwave belt 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, onions microwave belt dryer low temperature sterilization keep the nutrition and traditional flavor The onions microwave belt 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 onions microwave belt 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%.
