1、 The purpose of vacuum drying oven:

Electric heating vacuum drying oven is widely used in industries such as pharmaceuticals, chemical engineering, pharmaceuticals, food, light industry, plastics, scientific research and education for low-temperature or high-temperature drying and baking. It has the advantages of fast drying speed, low pollution, and no damage to the internal quality of the items that need to be dried. It is an environmentally friendly and green drying equipment that meets GMP requirements.

2、 Working principle of vacuum drying oven:

Electric heating vacuum drying oven is used to dry materials that need to be dried under vacuum conditions. It uses a vacuum pump to extract moisture and air, creating a vacuum state or near vacuum state in the working chamber, thereby reducing the boiling point of water, and using some heating measures (temperature can be controlled to prevent extreme temperatures that some materials cannot withstand) to accelerate the drying speed. Install an airflow splitter at the inlet of the oven to prevent direct contact between the airflow entering the oven and the material. The heating rack inside the oven is movable and can be quickly removed for cleaning internal residues.

3、 Characteristics of vacuum drying oven:
Each layer of the electric heating vacuum drying oven is equipped with electric heating tubes. Based on the principle of hot air rising, the heat conduction of each layer of the drying rack tubes is fully utilized, which can achieve a higher drying rate at lower temperatures and fully utilize heat. It is mainly suitable for drying heat sensitive materials, 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 and will not damage the formation of dried materials.
This product has achieved good results in the injection molding industry, mainly by heating the granular plastic raw material under vacuum (-0.06MPa - -0.09MPa) conditions before injection molding or drawing, controlling the temperature at 145 ℃, and holding for 4 hours. Under this condition, injection molding or drawing greatly improves the product yield and solves the problem of machine blockage.
This product has high drying efficiency for materials with high moisture content. Its biggest feature is the ability to raise the temperature to 200 ℃, with stable temperature control performance and small temperature differences. If a vacuum drying oven above 200 ℃ is required, an agreement must be made.
Install one airflow splitter at the inlet of the box to prevent direct contact between the airflow entering the oven and the material.
All four corners inside the box are made of smooth R-corners, with arched shapes on top and bottom, without burrs or unevenness.
