TECHNICAL FIELD

[0001] The utility model relates to probiotic freeze-dried powder manufacturing technical field, especially to a freeze-drying low-temperature low-oxygen crushing device. BACKGROUND

[0002] Probiotic freeze-dried powder is a kind of probiotic product prepared by vacuum freeze-drying technology, which can effectively preserve the activity and stability of probiotics, so that probiotics can be stored for a long time at room temperature. The common process of freeze-dried powder production includes: raw material preparation: firstly, the raw material is washed, peeled, cut or chopped, freeze-drying: the cut raw material is placed in the freezing chamber for freezing, so that it reaches the frozen state. Evaporation: the frozen raw material is placed in a vacuum evaporation device, and by controlling the change of temperature and pressure, the water in the raw material is directly converted into gas in solid form. Crushing: the evaporated raw material becomes a brittle solid and needs to be crushed to facilitate subsequent packaging and use. In the crushing process, a crusher is often used, in order to ensure the safety of construction personnel and the hygiene of construction environment, a closed crusher is often used in actual production to prevent dust from entering the environment, but the existing closed crusher has a certain explosion risk due to the production of powder-like objects, and the temperature in the closed crushing environment will rise due to the friction between the mechanical parts of the closed crusher and the raw material and the mechanical friction of the closed crusher itself, which may cause the loss of biological activity of freeze-dried powder and increase the risk of powder explosion.
