Oxytetracycline double cone vacuum dryer we know in a vacuum environment of vaporization of water occurs very quickly. For this type of heat-sensitive materials oxytetracycline drying process in order to speed up the drying rate blindly increasing the drying temperature often causes damage of product quality, and the oxytetracycline is placed in a vacuum drying, rapid evaporation of moisture and oxygen in a solvent of tetracycline at a low temperature environment which uses a vacuum dryer, to shorten the drying period of oxytetracycline is based on the effect of vacuum drying a basic principle: saturated water vapor pressure and temperature are closely related, how to use a vacuum dryer under vacuum, the boiling point of water is reduced, i.e., operating under vacuum is operating at low temperatures, can be avoided in the destruction of vitamins and other nutrients at a high temperature, while improving the drying speed. Also in the vacuum system vacuum dryer was good, the content per unit volume of air in an amount below atmospheric, at this relatively hypoxic environment for food drying can reduce or even avoid the chance of fat oxidation in foods, pigment browning or other oxidative deterioration, etc., so the use of vacuum-dried to obtain a better quality of food.
