Description

Technical Field

[0002] Sterilization equipment is needed when extracting polysaccharides from Polygonatum sibiricum. The sterilization equipment is a device that uses saturated pressure steam to quickly and reliably disinfect and sterilize Polygonatum sibiricum.

[0003] The existing sterilization equipment includes a sealing cover, a sterilization barrel, a stirring device and a steam supply pipe. The crushed polygonatum is placed in the sterilization barrel, the sealing cover is covered on the top of the sterilization barrel, and high-temperature steam is passed into the sealed space between the sterilization barrel and the sealing cover through the steam supply pipe. At the same time, the polygonatum is stirred by the stirring device, so as to increase the contact area between the polygonatum and the steam, and then the polygonatum is sterilized by the high-temperature and high-pressure steam. However, in the sterilization passage, only the liquid surface position of the polygonatum is in contact with the steam at the same time, and the contact area is small, which causes the sterilization time of the equipment to be extended. The extended time will cause the temperature of the steam to drop, thereby affecting the sterilization effect of the equipment and greatly reducing the practicability of the equipment.
