Conduction drying equipment in clean room workshop
Conduction dryer is a drying equipment that transfers heat energy to wet materials by conduction. It is more suitable for the situation: when the material cannot withstand high temperature or is easy to oxidize; when the material is dried, it is easy to generate powder; of steam. The vacuum tray dryer is a box-shaped drying device in which the wet material is heated by the heat exchanger under the tray, and the evaporated water is discharged in a vacuum state; the dryer has several heating pipes or hollow heating plates through which steam is passed through. The dried material is placed in the heating pipe or the drying tray on the heating plate, and the gas generated in the drying process is condensed and discharged by the vacuum pump; the vacuum tray dryer has a simple structure, but the material close to the wall may overheat. . The operation of the vacuum rake dryer is less labor-intensive than that of the box dryer, and it can recover the useful moisture in the material. The operating conditions are good, and the management is more convenient. damage.
Double-cone rotary vacuum dryer is a double-cone rotary tank. Under the vacuum state in the tank, steam or hot water is passed into the jacket for heating. The heat contacts the wet material through the inner wall of the tank, and the wet material absorbs The water vapor evaporated after heating is evacuated by the vacuum pump through the vacuum exhaust pipe; because the tank is in a vacuum state, and the rotation of the tank makes the material continuously turn up and down, inside and out, which speeds up the drying speed of the material, improves the drying efficiency, and achieves The purpose of uniform drying; the internal structure of the double-cone rotary vacuum dryer is simple, easy to clean, all materials can be discharged, and the operation is simple, which can reduce labor intensity and improve the working environment; because the material also rotates when the container itself rotates, but there is no accumulation on the wall. Therefore, the heat transfer coefficient is high and the drying rate is large, which not only saves energy, but also the material is dried evenly and fully, and the quality is good. It is suitable for drying materials that are easily oxidized, volatile, heat-sensitive and have special requirements for crystal shape. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for dust-free workshops and clean workshops.
Freeze-vacuum drying equipment in dust-free pharmaceutical cleanroom can be used not only as special equipment for the production of raw materials, but also as special equipment for the production of freeze-dried preparations; the freeze-drying unit is mainly composed of drying box, condenser, refrigerator, vacuum pump and heating It should be equipped with a hydraulic cap and plug device when it is used for lyophilizing agent, and a stainless steel partition that is not easily deformed should be used in the drying box. There are several layers of stainless steel or copper shelves in the drying box. Freezing pipes and heating pipes are embedded in the shelves, which can freeze or heat the products on the shelves. The sealing rubber ring is embedded around the door of the box and is coated with vacuum. grease to ensure sealing; there are several sets of spiral condenser tubes in the condenser, the temperature of which can reach -60 ~ -45 ℃, which is much lower than the temperature of the plate and the product in the drying box, the condenser will come from the sublimation of the product in the drying box. Condensation is carried out to ensure that the freeze-drying process continues; it is used to ensure that the temperature in the drying box in the sublimation stage reaches 80-100 °C.
