Abstract
Description
Technical Field
[0001] This utility model relates to the field of probiotic freeze-dried powder manufacturing technology, specifically to a freeze-dried powder screening and re-pulverizing equipment. Background Technology
[0002] Freeze-dried probiotic powder is a probiotic product prepared using vacuum freeze-drying technology. This technology effectively preserves the activity and stability of probiotics, allowing them to be stored at room temperature for extended periods. Common processes in freeze-dried powder production include: Raw material preparation: First, the raw materials are washed, peeled, and cut or chopped. Freeze-drying: The cut raw materials are placed in a freezer to reach a frozen state. Evaporation: The frozen raw materials are placed in a vacuum evaporation device, where, by controlling temperature and pressure changes, the moisture in the raw materials is directly converted from a solid to a gas. Pulverization: The evaporated raw materials become brittle solids and need to be pulverized for subsequent packaging and use. However, incomplete pulverization may result in the finished product containing large, uncrushed particles, leading to a decrease in product quality. Utility Model Content
