The future development of vacuum drying ovens for vacuum drying oven manufacturers will further study the drying mechanism and material drying characteristics, and master the development and improvement of dryers under the optimal operating conditions of different materials; in addition, large-scale, high-strength, high-economic, And to improve the adaptability of raw materials and product quality, is the basic trend of dryer development; at the same time further research and development of new efficient and adaptable dryers, such as combined dryers, microwave dryers and far infrared dryers.
Vacuum drying oven manufacturers explain why the vacuum drying oven should first vacuum and then heat up?
1. If the heating air is pumped out by the vacuum heating and then the vacuum is pumped out, the heat will be brought to the vacuum pump, which will cause the vacuum pump to rise too high, which may reduce the efficiency of the vacuum pump.
2. The heated gas is directed to the vacuum pressure gauge, and the vacuum pressure gauge will produce a temperature rise. If the temperature rise exceeds the operating temperature range specified by the vacuum gauge, the vacuum gauge may cause an indication error.
The correct method of using the vacuum drying oven should be to vacuum and then heat up. After the rated temperature has been reached, if it is found that the degree of vacuum has decreased, then add it appropriately. This is advantageous for extending the life of the device.
3. The workpiece is placed in a vacuum box to evacuate the vacuum to remove the gas components that can be removed from the workpiece material. If the workpiece is heated first, the gas expands when heated. Due to the excellent sealing of the vacuum box, the enormous pressure generated by the expanding gas may cause the observation window tempered glass to burst. This is a potential danger. This danger can be avoided by the procedure of first vacuuming and then heating up.
The vacuum drying oven of the vacuum drying oven manufacturer can also be used for drying chemicals. If the small molecules adsorbed on the surface of the compound are to be excluded, the temperature of the vacuum drying oven must be set to be above 120 degrees Celsius. Two hours is enough to drive away the water molecules so that the true weight of the object can be measured. The oven can also be used to dry chemicals. If the small molecules adsorbed on the surface of the compound are to be removed, the temperature of the vacuum oven must be set to be above 120 degrees Celsius for two hours to make the water The molecule is driven away so that the true weight of the object can be measured.
The vacuum drying ovens of vacuum drying oven manufacturers are widely used in research fields such as biochemistry, chemical pharmacy, medical and health, agricultural research, environmental protection, etc., for powder drying, baking and disinfection and sterilization of various glass containers. It is especially suitable for fast and efficient drying of heat sensitive, easily decomposable, oxidizable substances and complex ingredients.
