Description

The ZB series vacuum rake dryer is a novel horizontal intermittent vacuum drying equipment. Wet materials are evaporated through conduction and equipped with a scraper stirrer to continuously remove the material on the hot surface, and it forms a circulating flow inside the container. After the water evaporates, it is pumped out by a vacuum pump. This machine adopts a large-area sandwich heating method, with a large heat transfer surface and high thermal efficiency. It is equipped with stirring to form a continuous circulation state of materials in the cylinder, further improving the uniformity of material heating, and enabling smooth drying of slurry, paste, and paste materials.

The middle of the vacuum rake dryer body is cylindrical, and the inside and outside of the body are divided into three layers. The heating medium in the middle jacket can be thermal oil circulation (pressure<0.3mpa gauge pressure) or steam (pressure<0.3mpa gauge pressure). The outer layer is made of ultra-fine glass wool, which has good insulation effect and low energy consumption. The inner layer is filled with materials, especially suitable for drying materials that are at risk of oxidation and heat sensitive materials, without damaging crystalline materials during the drying process, The strict restriction on materials containing metal ions and the requirement for the recovery (or toxicity) of volatile (or toxic substances to be discharged further demonstrate its superiority

The vacuum rake dryer is easy to operate and convenient for entering and exiting materials, greatly reducing the labor intensity of workers. At the same time, it also reduces the environmental pollution of materials during the drying process, improves product quality, and meets the requirements of the drug management standard "GMP".
