With the upgrading of consumer food quality demand, freeze-drying and lyophilization technology realized by freeze dryer and lyophilizer has become the core processing technology of high-end healthy food, and vacuum freeze dryer equipment is widely used in fruit, vegetable, snack, coffee and nutritional food processing.
The biggest advantage of bench-top freeze dryer and industrial lyophilizer in food processing is the complete retention of nutritional ingredients. Low-temperature vacuum freeze-drying avoids the destruction of vitamins, dietary fiber and natural pigments by high temperature, and the nutrition, taste and color of food are completely consistent with fresh raw materials.
Secondly, freeze-dried food processed by industrial freeze dryer has excellent rehydration. The porous structure formed by lyophilization allows the food to quickly absorb water and restore the fresh state, which is convenient for storage, transportation and eating, and meets the fast-paced consumption demand of modern society.
In terms of food preservation, freeze drying machine can reduce the food moisture content to below 5%, effectively inhibiting the reproduction of microorganisms, no need to add preservatives, zero additives, safer and healthier, in line with the current healthy food consumption trend.
In addition, freeze-drying processing will not cause food shrinkage and deformation, maintaining the complete appearance of raw materials. It provides higher product added value for food enterprises and enhances the market competitiveness of high-end food products.
From small-batch food research and development with bench-top freeze dryer to large-scale mass production with industrial freeze dryer, lyophilization technology meets the full-cycle processing needs of food enterprises, and is an indispensable core technology for the upgrading of the food industry.
