The principle of freeze-dried yogurt block processing is to freeze liquid yogurt into a solid state at low temperature through a freeze-drying machine, and then sublimate the water in the solid yogurt in a vacuum environment to obtain porous solid freeze-dried yogurt blockage. Of course, the main reason for processing is that the freeze-drying process is carried out in a low-temperature vacuum environment, which can effectively retain the original nutrients and beneficial bacterial activity of yogurt, and can lock in color and aroma, facilitating long-term storage and transportation. This is also a good way to make freeze-dried yogurt cubes chew and eat! After brewing, it becomes a whole cup of yogurt. And its processing process mainly involves selecting qualified products for fermentation. So it is recommended that everyone choose ready-made fruits that meet their taste, diced frozen dried yogurt blocks, or beaten; Mix it with fruit and pour it into a food mold.

When processing freeze-dried yogurt blocks, the installed molds can also be quickly frozen at low temperature, then demolded and placed flat on the tray of the freeze-dried equipment; Place the tray into the freeze-drying chamber of the equipment for vacuum freeze-drying. After all of these are completed, you can wait until the equipment freeze-drying program automatically runs to obtain the dehydrated solid freeze-dried yogurt blocks, which are sealed and packaged for storage. In short, freeze-dried yogurt blocks are processed using the sublimation principle by low-temperature freezing crystallization in a food freeze-drying machine, followed by three stages of primary and analytical processing in a vacuum environment. The partition of FZG food freeze-drying machine has cooling temperature control, partition temperature control, and precise control of heating rate. During operation, the uniformity of his partition is controlled at ± 1 ℃. The vacuum degree control meets the range of 2.7~80pa. Therefore, during the production process of freeze-dried yogurt blocks, the entire drying process can be carried out in low temperature and vacuum environments, which can effectively control the sublimation rate, ensure that food raw materials do not collapse during the sublimation process, and thus ensure that the original molecular structure of yogurt blocks is not damaged or destroyed.
