product overview

Product Overview: Vacuum drying refers to heating and drying materials under vacuum conditions. If a vacuum pump is used for air and moisture extraction, the drying speed is accelerated.
Note: If a condenser is used, the solvent in the material can be recovered through the condenser. If the solvent is water, the condenser can be omitted to save energy investment.
Application scope

Suitable for low-temperature drying of thermosensitive materials that are prone to decomposition, polymerization, and deterioration at high temperatures; Widely used in industries such as pharmaceuticals, chemicals, food, electronics, etc., the water ring vacuum pump is combined with mechanical pressurization to improve the vacuum degree.
Performance characteristics

The boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force of the evaporator. Therefore, a certain amount of heat transfer can save the heat transfer area of the evaporator.
The heat source for evaporation operation can be low-pressure steam or waste heat steam.
The evaporator has less heat loss.
Before drying, disinfection treatment can be carried out, and there is no impurity contamination during the drying process, which meets GMP requirements.
◎ It belongs to a static vacuum dryer, so the shape of the dried material will not be damaged.

Product advantages

1. Constant heating temperature, increased vacuum degree, and accelerated rate; Constant vacuum degree, increasing heating temperature and rate;

2. By increasing both the vacuum degree and heating temperature, the rate is greatly accelerated.

3. The heating medium can be hot water, steam, or thermal oil.

4. The inner wall of the dryer adopts a circular arc transition to avoid hygiene blind spots and solvent condensation, which may drip into the first layer of material tray and contaminate the logistics.

When users have requirements, plate heat exchangers can be configured to increase the heat exchange area and improve the drying effect.

6. Due to the low temperature of the inner wall of the box, the material will form condensation after drying, so the top of the box is heated by a coil to ensure the temperature of the inner wall.
