In the 1980s, the bulk drug industry used this equipment as the main dryer. However, due to the difficulty in on-line cleaning and on-line sterilization of the tray, the drying speed was slow, and the labor intensity of the workers was large, and even after drying, Mixed powder mixing equipment, raw material drug production has been rarely used, mostly for medium and small trial production or package heat treatment Sullair compressor accessories.
The vacuum drying oven is an older drying device. The heated plates in the oven are divided into several layers. The hot plate or the low-pressure steam is used as a heating medium in the heating plate. The tray plated with the medicine to be dried is placed on the heating plate, the door is closed, and the inside of the box is vacuumized by a vacuum pump. The heating plate heats the medicine to a specified temperature in the circulating flow of the heating medium, and the water starts to evaporate and gradually withdraws with vacuum. This equipment is easy to control, can condense and recover the evaporated solvent, and the drug can not be contaminated during the drying process. It can be used for drying medicines, sterilization of packaging materials and heat treatment.
The vacuum drying oven is designed to dry heat-sensitive, easily decomposable and easily oxidized substances, and can be filled with inert gas. In particular, some complex components can also be quickly dried. Widely used in biochemical, chemical pharmaceutical, medical and health, agricultural research, environmental protection and other research and application fields, for powder drying, baking and various types of glass containers for disinfection and sterilization. It is particularly suitable for the rapid and efficient drying of dry heat-sensitive, easily decomposable, easily oxidizable substances and complex ingredients.
Vacuum oven precautions: 1. Vacuum box enclosure must be effectively grounded to ensure safe use. 2. The vacuum box should be used in an environment where the relative humidity is less than or equal to 85% RH, there is no corrosive gas around, there is no strong vibration source, and strong electromagnetic fields exist. 3. The vacuum box studio is not explosion-proof, anti-corrosive and other treatment, and must not be placed in a dry, explosive, easily corrosive gas. 4. The vacuum pump can not work for a long period of time, so when the vacuum degree reaches the requirement of the dry goods, the vacuum valve should be closed first, and then the vacuum pump power is turned off. When the vacuum degree is lower than the requirement for the dry goods, the vacuum valve and the vacuum pump power are turned on to continue vacuuming. This extends the life of the vacuum pump. 5. If the dry item is wet, it is better to add a filter between the vacuum box and the vacuum pump to prevent the humid gas from entering the vacuum pump and causing the vacuum pump to malfunction. 6. Dry items such as lighter and lighter in size and smaller in size (as small particles) should be vacuumed in the working chamber and septum nets to prevent damage to the vacuum pump (or solenoid valve) due to inhalation of dry matter. 7. After the vacuum box is used many times, there will be a phenomenon that vacuum cannot be drawn. At this time, the door seal should be replaced or the distance of the door buckle on the box should be adjusted to solve the problem. When the vacuum box drying temperature is higher than 200°C, slow air leakage will occur (except for 6050 and 6051). At this time, open the back cover of the box and use an Allen wrench to loosen the heater base, exchange the sealing ring or tighten the heating. Base to solve. 8. If the vent valve rubber plug is difficult to rotate, apply proper amount of grease to it. (eg Vaseline). 9. In addition to maintenance, the left side cover (except for type 6090 and 6210) cannot be removed to avoid damage to the electrical control system. 10. The vacuum drying oven should always be kept clean. The door glass should not be wiped with a reactive chemical solution and wiped with a soft cotton cloth. 11. If the vacuum box is not used for a long time, wipe the exposed plating parts with neutral grease to prevent corrosion. Put on the plastic film dust cover and place it in a dry room to avoid damage to the electrical components. use.
Vacuum oven features: 1, rectangular body studio, so that the maximum effective volume, microcomputer temperature controller, accurate and reliable temperature control. 2, steel, bullet-proof double glass door to observe the work room objects, at a glance. 3, the box closed tightness can be adjusted, the overall shape of the silicone rubber door seals to ensure high vacuum inside the box. 4, studio made of stainless steel (or drawing board) to ensure that the product is durable. 5. Storage, heating, testing, and drying are performed in the absence of oxygen or in an atmosphere filled with inert gas, so they do not oxidize. 6, the shortest heating time, and the traditional vacuum drying oven than the heating time by more than 50%. Drying ovens are large containers that can be set to maintain a constant temperature, drying wet glassware.
