Continuous high-concentration liquid sterilization concentration drying apparatus and continuous high-concentration liquid sterilization concentration drying apparatus method

Abstract

The invention relates to a continuous high-concentration liquid sterilization concentration drying apparatus and a continuous high-concentration liquid sterilization concentration drying apparatus method. According to the present invention, concentration drying is performed while the material can achieve the bacterial detection requirement; and a heating fluid media is filled between the inner pipe and the outer pipe of a jacket type single pipe heater, a material (primary concentrated liquid or extracted liquid) is introduced into the inner pipe, is heated by the heating fluid media inside the outer pipe, and is completely in a liquid phase state, the material is continuously heated by using a second-stage heater, the retention times of the material in the jacket type single pipe heater and the second-stage heater at the high temperature sufficiently achieve the condition required by sterilization, the material is subjected to an evaporation effect in a vacuum state from one point of the second-stage heater, the original material is separated into a film-like liquid and water vapor, the material is evaporated and concentrated into paste blocks or powder through an evaporation tank, and the material is rolled out to achieve a flat state through a vacuum dryer so as to be further evaporated.

Description

technical field [0001] The invention relates to a sterilizing device and a sterilizing device for the extract of Chinese patent medicine or natural seasoning, which has the functions of concentration and drying at the same time. Background technique [0002] From the pre-treatment stage of raw materials to the completion of the production process of pharmaceutical preparations in the manufacture of Chinese patent medicines, there is no sterilization engineering as a process control method, so the process control often fails to meet the relevant bacterial inspection requirements of laws and regulations. Because there is often no guarantee of sterilization process in the previous process, the finished product is unqualified in the bacterial inspection, and it can only be sterilized by radiation of radioactive elements such as cobalt irradiation in the finished product stage, and even adverse factors such as excessive irradiation may occur, which will affect the development of t...
