Hot air tray dryer is a continuous drying equipment for batch production, which is used for drying flaky, strip and granular materials with good air permeability.It is especially suitable for dehydrated vegetables, catalysts, Chinese herbal pieces and other materials with high moisture content.

This series of dryer has the advantages of fast drying speed, high evaporation strength and good product quality. For the paste materials of dehydrated filter cake, they can only be dried after granulating or making into strips.

The equipment has been widely used, sold to all over the world, and received the praise and trust of customers. It has many advantages, and the product performance is very good.

The advantages of hot air tray dryer

  1. Fast processing speed
  2. High product quality
  3. Sensitive response
  4. 4. Uniform heating
  5. Good quality

Working principle of hot air tray dryer

Microwave dryer is to use microwave penetrating heating to improve the temperature of the material, so that the water in the material vaporizes and evaporates. The evaporated water vapor is discharged by the dehumidification system to dry the material.

Schematic diagram

Hot air tray dryer is suitable for mass production of difficult drying materials with low drying rate. The equipment has compact structure, small floor space, simple operation, easy maintenance and stable operation.

It can be designed into different hot air circulation drying forms according to the drying characteristics of materials. It is the extension and improvement of hot air circulation oven, widely used in metallurgy auxiliary, chemical industry, food, packaging and other fields. With the development of enterprise technology and the improvement of product technology, the multi-layer belt dryer has the ability of large production, diversification, centralized control and continuous production. It has the advantages of high efficiency, energy saving and easy management.
