Product Overview :
The so-called vacuum drying refers to heating and drying the dried material 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.
Working principle
The so-called vacuum drying refers to heating and drying the dried material 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.
Performance characteristics
◎ The boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force of the evaporator, 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.
◎ 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 thermosensitive materials that are prone to decomposition, polymerization, and deterioration at high temperatures; 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 physical properties, initial moisture content, final moisture content, temperature, vacuum degree, drying amount, and drying time of the dry material. There are four heating methods for the same model of vacuum dryer, namely steam hot water, heat transfer oil, and electric heating. For example, in order to increase the drying capacity, the number of drying rack layers can be appropriately increased. Please inform our factory in a timely manner.
◎ Our factory can provide and install the accessories for the vacuum drying system mentioned in the user manual. Please specify when placing an order.
◎ Our company can provide design, manufacturing, and installation services for special requirements in vacuum drying systems raised by users.
◎ Our company implements three quality guarantees for our equipment, and all accessories are provided for a long time. Please rest assured.
