MZG series pulse square vacuum dryer-Changzhou Yufeng Drying Equipment Co., Ltd.

1、 Product Overview
The pulsating vacuum dryer uses a vacuum system to extract air and moisture, creating a vacuum state in the inner cavity, reducing the boiling point of water, and accelerating the drying speed. Pulse type vacuum dryer belongs to static vacuum drying equipment. The material is placed on a layer board inside a square vacuum dryer in a drying tray, and a heat medium is introduced into the layer board. The heat of the heat medium is transferred to the material through the drying tray for drying. The equipment consists of a drying tray, a shelf layer, a box, a vacuum system, a heating system, a pulse bubble system, a monitoring system, and valve pipelines.

2、 Product advantages
1. Greatly improve drying efficiency and shorten drying time by over 75%
2. Compared to a drying oven, it saves over 200% energy
3. Less equipment is required under the same production capacity, saving factory space.
4. Better product uniformity, better quality and color of dried products
5. The dried finished product is honeycomb shaped
6. High pressure gas pulse secondary bubble process
