The vacuum drying oven is an older drying device, and the heating plate in the box is divided into several layers. Hot water or low-pressure steam is used as a heating medium in the heating plate, and the tray on which the medicine to be dried is placed is placed on the heating plate, the door is closed, and the vacuum is pumped in the box. The heating plate heats the drug to a specified temperature in the circulating flow of the heating medium, and the moisture begins to evaporate and is gradually withdrawn by vacuuming. The device is easy to control, can condense and recover the evaporated solvent, and the drug is not easily contaminated during the drying process, and can be used for drying the drug, packaging sterilization and heat treatment.
In the 1980s, the raw material medicine industry used this equipment as the main dryer. However, because it is not easy to carry out online cleaning and online sterilization of the tray, the drying speed is slow, the labor intensity of the workers is large, and in order to achieve uniformity of the medicine, it is necessary to dry after drying. It has been mixed by the mixing equipment, and it has been rarely used in the large-scale production of raw materials. It is mostly used for medium and small trial production or heat treatment of Shouli air compressor parts.
The electrothermal constant temperature vacuum drying oven has simple performance and structure, but it has different options according to the requirements of its use. Electric heating constant temperature drying box can be divided into: electric blast air temperature drying oven; electric heating constant temperature drying box. According to the material, it can be divided into: stainless steel liner drying oven; ordinary carbon steel drying oven. Press display mode: digital display; pointer display. According to the temperature, it can be divided into: 200 degree drying box; 300 degree drying box; 500 degree drying box, in the drying box product, the high temperature of Zui can only reach 500 degrees, if the demand for temperature in use is greater than this 500 degree, Then we must choose a box type electric furnace to meet the needs of the experiment.
