Multi layer automatic belt dryer

Working principle of belt dryer:

The multi-layer automatic belt dryer adopts the principle of utilizing hot air in multiple layers. The interior of the host is composed of multiple layers of stainless steel mesh belts, which are supported by the support rods below. The support rods are made of seamless stainless steel pipes and are driven by chains on both sides. There are baffles on the top of the chains to prevent materials from falling into the middle of the track. The mesh belts are fixed on the support rods. The pure hot air from the heat exchanger is sent to the bottom of the dryer through the air supply fan. It first passes through the bottom mesh belt and exchanges heat with the dry material to remove some moisture. Then, it passes through each layer of mesh belt layer by layer, forming a counter current heat exchange with the material. After reaching the top layer and exchanging heat with the wet material, the humid air is basically saturated. The induced draft fan is used to discharge the humid air outside through the dehumidification outlet. Adopting forced dehumidification airflow, multi-layer belt circulation flipping, layer by layer drying of materials, fully utilizing hot air, rapid drying and dehydration, high operating efficiency, and minimizing energy consumption.

Purpose:

The DWT series belt dryer is a continuous drying equipment used in mass production, used for drying sheet, strip, and granular materials with good breathability. It is particularly suitable for dehydrated vegetables, Chinese herbal medicine slices, and other materials with high moisture content and material temperature that cannot be high; This series of dryers has the advantages of fast drying speed, high evaporation intensity, and good product quality.

For dehydrated vegetables, DW belt dryer is suitable for secondary cleaning and drying of cassava chips, bitter gourd chips, konjac chips, jujubes, goji berries, ginger chips, bamboo shoots, white radish chips, chili peppers, green vegetables, chili peppers, vegetable peppers and other vegetables, pumpkin, potatoes and other bulk and large particle materials. It is also suitable for drying Chinese medicinal materials, especially for materials that do not allow high temperature drying. Vegetables with strong seasonality can be processed in a timely manner, which can avoid seasonal storage and cause economic losses due to mold and deterioration; In addition, the dryer adopts the drying principle of belt through flow thermal cycle, which has good energy-saving effect. At the same time, the dryer can adjust the temperature and belt speed according to the moisture content and thermal sensitivity requirements of the dried material, so that the quality requirements of color, aroma, and taste of the dried material are not changed, and the original quality of vegetables is maintained. Therefore, it has good economic and social benefits.

Note: The device model, size, and number of layers can be customized according to the actual processing capacity of the materials dried by the customer.

The equipment uses a conveyor to transport materials to the first layer of the dryer's mesh belt (top layer), smoothly moving forward with the transmission device, and then falling onto the second, third, fourth, fifth, sixth, and seventh layers of mesh belts (with a stopper plate on the edge of the mesh belt to prevent the materials from falling off), and automatically discharging. This equipment has a high degree of continuous production and automation, reducing labor and lowering costs.
