Vacuum Drying Oven, as the name suggests, needs to be vacuumed. The working principle of the vacuum Drying Oven is to put the material into the vacuum box to evacuate and extract the gas components. It is usually used in conjunction with other instruments and equipment in the laboratory such as glass reactors, circulating water Vacuum Pumps, and rotary evaporators. The vacuum Drying Oven needs to be heated when drying the material. At this time, if the vacuum Drying Oven is used for drying, the gas generated by the gas cannot be discharged after the material is heated, and an explosion may occur. The sealing of the vacuum Drying Oven is very good. When using the vacuum Drying Oven, it must be vacuumed before heating.
Before increasing the drying rate of the vacuum Drying Oven, it is necessary to know which factors are easily affected by the drying rate of the vacuum Drying Oven. The vacuum Drying Oven is a box-type drying equipment that dries the dry material under negative pressure conditions. It can obtain a higher drying rate at a lower temperature. It is mainly suitable for heat-sensitive materials and materials containing solvents and materials that need to be recovered. dry.
From the name, the vacuum Drying Oven is used to dry materials. In addition to the factors of the material itself, the factors that affect the drying rate of the vacuum Drying Oven include the degree of vacuum. The factors of the material itself, such as size, shape, etc., as well as the moisture content, density and viscosity of the material itself, in this case, in order to improve the drying rate of the vacuum Drying Oven, it is necessary to increase the initial drying rate of the material. Method 1 is to reduce the moisture content of the material after vacuum filtration pretreatment; method 2 is
to reduce drying cracks, which is conducive to uniform and rapid drying;
method 3 speeds up the diffusion speed in the green body and saves the time for drying the green body. shorten the drying time by 15%-40%, which can also improve the drying rate of the vacuum Drying Oven; the
last method is to reduce the molding moisture without increasing the power consumption, and the decrease of moisture will also increase the drying efficiency of the vacuum Drying Oven. drying rate.
