Description

Meanwhile, UHT sterilization equipment has high working efficiency, can process large batches of foods, saves time and cost, and is widely applied to food production processes at present.

The current sterilization tank generally comprises a tank body, a feed inlet, a discharge outlet steam inlet and a coiled pipe, wherein the feed inlet and the discharge outlet are arranged on the tank body, plant extract to be sterilized is introduced into the tank body through the feed inlet, steam for sterilization is introduced into the tank body through the steam inlet, the plant extract passes through the coiled pipe, and the plant extract in the coiled pipe is sterilized by utilizing the high temperature of the steam.

However, the outer layer of the heat-resistant spore is generally provided with a protective shell, and the protective shell can generate stronger stress and protective reaction under severe conditions such as high temperature and the like, so that the heat-resistant capability of the heat-resistant spore is further enhanced and is not easy to kill. When UHT sterilization equipment is used for sterilization in the field of food, the food contains rich protein, and the heat resistance of the protein is poor, so that the sterilization of the food is generally realized by keeping the temperature above 135 ℃ for a period of several seconds to tens of seconds, and most of bacteria and viruses can be killed at the temperature and in time, and the nutritional ingredients of the food are not easily influenced.

Namely, when the UHT sterilization device is used for sterilization in the food field, the sterilization time is generally shorter in order to ensure the nutrition of the food, so that the sterilization effect of the UHT sterilization device on the heat-resistant spores is generally weaker, and under the limit of the extremely short sterilization time, a large number of or particularly strong heat-resistant spores are generally difficult to kill, so that the sterilization effect is not optimistic. Thus, there is still room for improvement.
