In the High Cost Performance Freeze-drying process, the dried items need to be pre-frozen. The basic purpose of pre-freezing of the product is to immobilize the solid particles in the product during the sublimation of the moisture to prevent physical and chemical reactions of the product. Since liquid products composed of various organic or inorganic materials usually form a eutectic state after pre-freezing, for each product to be freeze-dried, the corresponding eutectic point temperature, that is, the product, should be found. The temperature at which the structural water freezes, and the pre-freezing temperature is also required to be lower than the eutectic point temperature, so that the product is kept in a frozen state, otherwise a product having good properties cannot be obtained. If the pre-freezing temperature is not low enough, the product may not be completely frozen, and it will expand and foam when vacuuming and sublimation; if the pre-freezing temperature is too low, it will not only increase unnecessary energy consumption, but also reduce it for some biological drugs. Survival rate after lyophilization.
In addition, the pre-freezing rate of the product also has a large effect on the drying effect. Rapid cooling is required between the freezing point and the eutectic point temperature of the product, otherwise the living body protein is easily deteriorated. The crystals formed by the crystals are fine and large in rapid cooling. Such ice crystals are slow in sublimation, but dissolve quickly after drying, which can reflect the original structure of the product; the ice crystals produced by slow cooling are large, which is not conducive to sublimation, but dissolves slowly after drying. So, we need to test a suitable cooling rate,
Therefore three data should be determined before pre-freezing. One is the rate of pre-freezing. The rate of pre-freezing should also be different for different products. The second is the minimum temperature for pre-freezing. The minimum temperature for pre-freezing should be lower than the temperature at the eutectic point. The third is the time of pre-freezing. All products are frozen before vacuuming. Don't get out of the bottle due to vacuuming,
