DW-Multi-layer belt dryer
product introduction
DW series multi-layer belt dryer is a continuous drying equipment for batch production. It is used for drying sheet, strip and granular materials with good air permeability. It is especially suitable for materials with high moisture content such as dehydrated vegetables, catalysts, and traditional Chinese medicine pieces. The temperature of the material is not allowed to be high; this series of dryers has the advantages of fast drying speed, high evaporation intensity, and good product quality. Pasty materials such as dehydrated filter cakes need to be granulated or made into strips before drying.
overview
DWB series multi-layer belt dryers are suitable for large-scale production of hard-to-dry materials with low drying rates. The equipment has a compact structure, a small floor area, simple operation, convenient maintenance, and stable operation. It can be designed into different hot air circulation drying forms according to the drying characteristics of materials. It is an extension and improvement of the hot air circulation oven and is widely used in metallurgical additives, chemicals, food, packaging and other fields. With the technological advancement of enterprises and the improvement of product technical content, multi-layer belt dryers have the ability to meet large-scale production, diversification, centralized control, and continuous production. It has the advantages of high efficiency, energy saving and easy management.
