Steam sterilizing device of crude drug of Tibetan medicine

Abstract

The invention relates to a steam sterilizing device of a crude drug of a Tibetan medicine, comprising a sterilizing bin and a cooling bin, wherein the sterilizing bin is provided with a sterilizing bin feeding hole and a sterilizing bin discharging hole, and the cooling bin is provided with a cooling bin feeding hole and a cooling bin discharging hole; the cooling bin feeding hole is connected with the sterilizing bin discharging hole; a gas exhaust port is arranged on the upper part of the sterilizing bin; a rotary agitator is arranged in the sterilizing bin which is provided with a hot air inlet; the hot air inlet is provided with a first branch air inlet and a second branch air inlet; the first branch air inlet is connected with a first hot air induced draft fan through a pneumatic valve; and the second branch air inlet is respectively connected with a second hot air induced draft and a steam generator through an energy-accumulated steam heat exchanger. The invention solves the problems that the steam sterilizing device in the prior art does not preheat or thoroughly preheat and is easy to generate condensed water, is especially suitable for sterilizing devices of crude medicinal materials of the Tibetan medicine, traditional Chinese medicinal materials, Chinese patent drugs, food, seasonings and other raw materials.

Description

technical field [0001] The invention relates to a sterilizing device, in particular to a superheated steam sterilizing device used in the field of original Tibetan medicines, traditional Chinese medicine raw materials, food seasonings and other similar raw materials. Background technique [0002] Sterilization technology belongs to the basic technology of microbiology, which uses physical and chemical means to kill or remove the vegetative cells and their spores (or spores) of all microorganisms in the culture medium, fermentation equipment or other targets, so as to achieve the purpose of sterility. Sterilization technology is a necessary condition for culture medium, fermentation equipment or other target substances to obtain pure culture, and it is an indispensable technology to ensure food and drug safety in the food industry and pharmaceutical fields (especially in the field of traditional Chinese medicine production). [0003] The thoroughness of the sterilization tech...

Problems solved by technology

[0008] For this reason, the first technical problem to be solved by the present invention is that the steam sterilization device in the prior art uses a jacket outside the sterilization chamber to preheat the sterilization chamber before sterilization, which is easy to The instant contact between the steam and the normal temperature tank will produce condensed water, which will lead to uneven and incomplete preheating of the sterilization chamber, making the temperature in the local area of ​​the chamber low; then after the high temperature steam enters the chamber, it will be due to The local low temperature causes the temperature to drop and condense, so that the raw material is soaked and damp after entering the cavity, so as to provide a uniform and sufficient preheating treatment for the device before sterilization, and the raw material enters the sterilization environment.
