The working principle and application field of vacuum drying oven

Electrothermal vacuum drying welding oven molding, the shell is treated with high-strength electrostatic spray coating, and the paint film is smooth and firm. The studio is made of 304 stainless steel plate welded and welded between the studio and the outer casing. The interior of the studio is equipped with a biosafety cabinet shelf for placing various test items. The mica heater is installed around the outer wall of the working room. The door seal is sealed with a silicone rubber strip, and the door is provided for observation. The window can be controlled by a solenoid valve metal hose, and the electrical box is mirrored on the left side of the cabinet. The evacuation and inflation of the electric vacuum drying oven are either lower or lower, and the front panel of the electrical box is provided with a vacuum gauge, a temperature control instrument and a control switch compensator, and the electrical box is provided with electrical components.

It is used in research and application fields such as medical care and environmental protection, and is used for powder drying, baking and disinfection and sterilization of various glass containers. It is especially suitable for fast and efficient drying of heat sensitive, easily decomposable, oxidizable substances and complex ingredients.

working principle

The electric vacuum drying oven maintains a certain degree of vacuum in the working chamber and uses an intelligent digital temperature controller for temperature setting, display and control. The temperature regulator uses computer technology to collect and process the temperature signal in the working room. The temperature control system is intelligent temperature control, reliable in performance and convenient to use.

Intelligent temperature regulators have over temperature protection. When the temperature in the work transaction room exceeds the set temperature value during the working process of the equipment, the over-temperature protection circuit operates to cut off the heating circuit, which is safer and more worry-free. The advantages of vacuum technology drying have the following advantages over conventional drying techniques:

For samples that are not easy to dry, such as powder or other granular samples, vacuum drying can be used to effectively reduce drying time;

The vacuum environment greatly reduces the boiling point of the liquid, so vacuum drying can be easily applied to heat sensitive substances;

Safer to use - under vacuum or inert conditions, completely eliminate the possibility of oxides exploding, the powdered sample will not be blown by the left side of the flow, compared to ordinary drying by air circulation, moving

Organic Spirulina powder

Organic spirulina powder is extracted from 100% natural spirulina. Spirulina is neither an animal nor a plant, it is actually a natural freshwater alga. Its protein content is incredibly high. It also contains iron, vitamin B6, and several other micronutrients. Ensuring that micronutrient intake is maintained is very important to ensure optimal physical condition.
