FZG series square vacuum dryer

Working principle

Vacuum drying equipment is divided into static dryers and dynamic dryers. The FZG series square vacuum dryer belongs to a two static vacuum dryer. Vacuum drying is the process of heating and drying dried materials under vacuum conditions. It uses a vacuum pump to extract air and moisture, keeping the working chamber in a vacuum state, greatly accelerating the drying rate of materials, and saving energy. It has the advantages of fast drying speed, low pollution, and no damage to the internal quality of the dried goods.

scope of application

Suitable for low-temperature drying of thermosensitive materials that are prone to decomposition, polymerization, or deterioration at high temperatures. Vacuum dryers have good sealing properties, making them also suitable for drying materials that require solvent recovery and contain strong irritants and toxic gases. Vacuum drying is widely used in industries such as pharmaceuticals, chemicals, food, dyes, etc. The air meets the requirements of the drug management standard "GMP".

characteristic

1. The gasification rate of liquids increases with the decrease of atmospheric pressure (the boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force for evaporation, thus saving the heat transfer area of the evaporator for a certain amount of heat transfer. The heat source for evaporation operation can be low-pressure steam or waste heat steam and hot water circulation).

2. Equipped with a condensation recovery device, the solvent can be recovered.

3. Dry, clean, and pollution-free in a sealed state. Disinfection treatment can be carried out before drying, and no impurities are mixed in during the drying process

4. The evaporator has less heat loss, and the heat source for evaporation operation can be low-pressure steam or waste heat steam.

5. It belongs to a static vacuum dryer, so the shape of the dried material will not be damaged.

6. This machine can achieve a higher drying rate at lower temperatures, fully utilize heat, and is mainly suitable for drying heat sensitive materials and materials containing solvents and solvents that need to be recovered. Disinfection treatment can be carried out before drying, and no impurities are mixed in during the drying process. This dryer belongs to a static vacuum dryer, so the formation of dried materials will not be damaged. Heating methods include steam, hot water, thermal oil, and electric heating.
