Working principle
The so-called vacuum drying refers to heating and drying dry materials under vacuum conditions. If a vacuum pump is used for air extraction and dehumidification, 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 used to save energy investment.
Performance characteristics
The boiling point of the material solution under vacuum decreases, 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.
Adapt to materials
Suitable for low-temperature drying of heat sensitive materials that are prone to decomposition, polymerization, and deterioration at high temperatures; It is widely used in industries such as pharmaceuticals, chemicals, food, electronics, etc.

Ordering Instructions
When placing an order, please choose a suitable vacuum dryer based on factors such as the initial moisture content and final moisture content of the dried material, temperature, vacuum degree, drying amount, and drying time. There are four heating methods for steam hot water thermal oil electric heating in the same model of vacuum dryer. For example, in order to increase the drying capacity, it is advisable to increase the number of layers of the drying rack. Please inform our factory in a timely manner.
Our factory can provide and install the accessories in the vacuum drying system mentioned in the user manual. Please specify them when placing an order.
Our company can provide design, manufacturing, and installation for special requirements in vacuum drying systems proposed by users.
Our company's equipment implements three guarantees of quality for users. All accessories are provided for a long time, please rest assured.
