FBL vacuum drying oven for sale:
DZF 6050 vacuum oven and blast drying oven are two kinds of drying equipment commonly used in our laboratory. We know that to dry the dry material, it is nothing more than to achieve the purpose of drying by direct heating, vacuuming and negative pressure dehumidification. When we choose a drying oven, we must understand the difference and application range between a industrial vacuum drying oven and a blast drying oven.
Through the direct heating method, of course, there are also the auxiliary method of blasting and exhausting. It searches for moisture, solvent or volatile component molecules in the material by thermal action, so that the molecules move rapidly to separate from the dry material and gradually make the material get dry. Its drying speed can be very fast and the drying temperature can be very high.
The difference between industrial vacuum drying oven and blast drying oven:
The vacuum drying oven cost and the blast drying oven look similar, but they are actually very different. The main differences are as follows.
The vacuum drying box uses a vacuum pump to pump the space where the dry material is located to a negative pressure, that is, the so-called vacuum state. In a vacuum state or a low pressure state, the boiling point of the moisture, solvent and other volatile components in the material decreases, so that it can be separated from the surface of the material particles and be pumped away by the vacuum pump at a lower temperature. It is mainly used in those materials that oxidize, polymerize and undergo other chemical reactions at high temperatures. Of course, it also has the dual effect of heating to accelerate the volatilization of moisture, solvent and volatile components so as to separate from the surface of the material.
1. The electric heating method is used in theindustrial vacuum drying oven to carry out the blast circulation drying test. The ventilation circulation fan blows out hot air to balance the temperature in the industrial vacuum drying oven. The vacuum drying box chooses a vacuum pump to evacuate the internal air, so that the air pressure in the box is lower than normal pressure, and the test is performed in a vacuum clean environment. The industrial vacuum drying oven, under the action of the fan, quickly takes away the volatile substance molecules volatilized from the surface of the material through air exchange, so as to achieve the effect of drying the material quickly.
Application: Widely used in electromechanical, chemical, plastic, light industry and other industries and scientific research units for baking, drying, curing, heat treatment and other convenient heating of various products and test samples. High temperature industrial vacuum drying oven, beautiful appearance, easy to use, sensitive and accurate temperature control.
2. Regarding the choice of temperature control, the temperature range of the vacuum drying oven is up to 250 degrees Celsius, and the maximum temperature of the general industrial vacuum drying oven is 300 degrees Celsius. In this process, the higher the temperature, the higher the product cost. When the temperature is between 250 and 300 degrees Celsius, the aging of the test chamber with poor materials and accessories will accelerate. At this time, it is necessary to select products from regular manufacturers. , in order to ensure the quality of the test.
3. The vacuum drying oven is often used for heat-sensitive substances, easily volatile materials, easily decomposed materials or granular experimental items. The use of industrial vacuum drying oven is relatively common, but the environment of the drying oven is not guaranteed.

Application: Widely used in research and application fields such as electronics, aerospace, military weapons, automobiles and ships, petrochemicals, agriculture, forestry and environmental protection, commodity inspection and drug inspection, medical disease control, pharmaceuticals, biochemistry, medical and health care, and environmental protection. It is especially suitable for rapid drying of heat-sensitive, easily decomposed, easily oxidized, and complex components in scientific research, universities and enterprises. It can also be used for accelerated drying of powders and other substances.
4. There is also the company's purchase budget. The price of blast drying oven is much cheaper than that of what is vacuum drying oven. If customers want to choose cheaper products, it is recommended to buy blast drying oven.
Summarize:
1. The same point of what is vacuum drying oven and blast drying oven: whether it is a vacuum drying oven or a blast drying oven, it can be used for drying, drying, baking and melting wax, and sterilization. They are used in biochemistry, chemical pharmaceuticals, medical It plays an important role in research applications such as sanitation and environmental protection, and is one of the commonly used experimental equipment in laboratories.
2. The difference between the what is vacuum drying oven and the blast drying oven: the drying principles of the two are different. The vacuum drying oven uses the principle of vacuuming to achieve the drying of the items, while the blast drying oven uses the blast cycle of the box to drive the flow of hot air. So as to achieve the purpose of drying.
