Powder sterilization room and powder sterilization method

Abstract

The invention discloses a powder sterilization room and a powder sterilization method, and the powder sterilization room comprises a heat exchange room and a sterilization pipe, wherein an air inlet pipe is arranged below the heat exchange room, an air outlet pipe is arranged above the heat exchange room, and two ends of the sterilization pipe respectively extend out of the feed port and discharge port of the heat exchange room; and the powder sterilization method comprises the following steps: a) adding hot air into the heat exchange room through the air inlet pipe; b) adding powder to be sterilized and sterilizing steam into the sterilization pipe through the feed port; c) enabling the powder to be suspended in the sterilizing steam through a fan so as to form mixed gas; and d) separating the sterilized powder which flows out of the discharge port from the sterilized air through a cyclone separator. By utilizing the method, easy occurrence of denaturation or wetting and caking of the powder after sterilization can be avoided; and simultaneously, the sterilization speed is faster, and energy conservation is realized. The powder sterilization room and the powder sterilization method can be widely applied in powder sterilization.

Description

technical field [0001] The invention relates to a sterilization chamber, in particular to a sterilization chamber for powder sterilization and a powder sterilization method. Background technique [0002] At present, in the pharmaceutical and food industries, the trend of requiring sterilization of powder articles is becoming more and more intense, but the most safe and reliable sterilization method is still the most widely used moist heat steam sterilization. There are many powders that cannot withstand the long-term high-temperature and high-humidity action of high-pressure saturated water vapor, and cannot be sterilized by the pressure steam sterilization equipment currently available on the market. Although many sterilization equipment manufacturers have developed traditional Chinese medicine sterilizers to sterilize traditional Chinese medicine powder, because they all use saturated water vapor for long-term sterilization, the types of powder are limited and the steriliz...
