Product Description

Applications

DW mesh-belt dryer is continuous dryer for large production.lt is usedfor drying sheet materials,bar masterials granules materials thathave good air permeability. As to dehydrated vegetable Chineseherb pieces which have high moisture and need low dryingtemperature,DWT belt dryer is specially suitable.

Principle of work

The materials are uniformly put on the mesh-belt by the material charger. The mesh-belt used generally 12-60 mesh stainless steel wire net and it is drewn and moved inside the driver by a transmission device. The drier is composed of several units.For each unit,the hot air is circulated separately. In the first unit,air out from circutation sir blower(5)pass through beside into low unit,after air is up and heated by steam heater(4), be shared by seperater(3), the air is spraies through mesh-belt in to top of machine. The drying process is hot air passes through the mesh-belt covered with asprcial moisture from the top to the bottom of from the bottom to the top, and this will complete the heat and mass transfer process. The air pipe of the top is conected with fan, one part of air is circulated, some exhausted gas is discharged with a spesial moisture eilmination blower,and other waste gas is control I es through an adjutment eilmination blower,and other waste gas is controlles through an adjustment valve. The top and low circulation units can be freely equipped according to the usersi demand, The unit number can be selected according to the demand.

DW series belt dryer is a continuous equipment for batch production, used for drying of sheet, strip and granular materials with good air permeability. It is particularly suitable for dehydrated vegetables, high water content and not high material temperature; this series dryer has the advantages of fast drying speed, high evaporation strength and good product quality. For the paste material of dehydrated filter cake, it can also be dried after granulation or rod making.
For dehydrated vegetables, the belt dryer is generally used in series to form the initial dry section, middle section and final dry section. In the initial dry section, due to the high water content and poor air permeability, the thin laying material thickness, fast running speed and high drying temperature are adopted. If the material temperature does not allow more than 60ºC of material, in the early dry section, the dry gas temperature can be higher than 120ºC, the final dry section of the material stay time is 3-6 times of the early dry section, the material thickness is 2-4 times of the early dry section, for the material temperature not exceeding 60ºC, can use about 80ºC dry gas, using multiple combination band dryer, can better play the drying performance of belt, make the drying more uniform.
DW belt dryer is suitable for garlic, carrots, white radish, mushrooms, vegetables, pepper and other vegetables, pumpkin, potato, lifting, Jerusalem artichoke, bamboo shoots, apples, and Marine life and other block, large particulate matter material dry, It is also suitable for drying the slices of Chinese medicinal materials, Especially suitable for materials that do not allow high-temperature drying, More seasonal vegetables can be processed in time, Can avoid seasonal pressure storage caused by mildew and deterioration caused by economic losses; in addition, The dryer adopts the drying principle of belt penetrating heat cycle, With a good energy saving around, At the same time, according to the moisture content of the drying material and the thermal sensitivity of the material, the dryer can adjust the temperature and the speed of the net belt, Make the dry material does not change the color, aroma, flavor quality requirements, Maintains the original quality of vegetables. Therefore, it has the good economic benefits and the social benefits.
According to the specific situation, the transmission mode of metal belt drying trunk can be selected from network chain type, net belt type, string rod type, iron-dragon type, belt type, pass type or suspension type, and the transmission speed of 0.1-8 m / minute can be adjusted. The length, width and height of the drying furnace body are customized according to the size of the drying object. The heating method can use electric heating pipe + air transport, biomass, coal, oil and steam burner, quartz pipe heating, diesel burner heating, far infrared radiation heating as the heat source. The temperature can be controlled in sections, and the temperature controller accurately sets the temperature required for drying. A fog discharge valve is set above the line body, through which the water vapor is discharged from the furnace chamber. The furnace is equipped with a hot air circulation system to ensure a uniform and stable temperature. The whole made of stainless steel structure, beautiful and durable.
