Sterile sampling valve

Abstract

The present invention relates to a sterile sampling valve used on production pipelines or tanks for fizzy drinks, such as beer, cola, fruit milk, etc in order to solve the technical problems existing in the prior art that the sterilization and the oxygen isolation of valve cavities can not be ensured as the sampling valves used food industry are always exposed in the air, the cleaning operation is complicated, etc. The sampling valve comprises a sampling valve body and a sampling valve jacket. The sampling valve body is movably sheathed in the valve jacket. The valve jacket is divided into an upper cavity and a lower cavity by the valve body, wherein the lower cavity is sealed, and the upper cavity is open. As the sampling valve body is arranged in the valve jacket rather than directly exposed in the external environment, samples taken are effectively protected from pollution. Besides, the immersion of the sampling valve body in a sterilizing agent performs the double functions of sterilization and oxygen isolation. The sterilization operating steps for the valve body can be simplified during sampling, and the microbe sampling efficiency is improved. Even though the valve is not thoroughly cleaned after sampling, the sterile state of the valve body can still be well ensured.

Description

technical field [0001] The invention relates to a sampling valve used on the production pipeline or tank body of beer, cola, fruit milk and other foamed beverages, in particular to an improved aseptic sampling valve. Background technique [0002] For the food industry, the term hygiene means creating and maintaining a hygienic and wholesome production environment. In order to provide safe and hygienic food, food must be processed in a clean environment by healthy practitioners to prevent food-borne diseases caused by microbial contamination, while minimizing the reproduction of microorganisms that cause food spoilage. Most of the modern beverage production enterprises rely on the tank structure for production and transportation through pipelines. The demand for product quality control (physical and chemical testing, microbial testing, taste evaluation, etc.) determines that sampling valves should be installed on equipment and pipelines to facilitate smooth sampling and ensu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problems existing in the prior art that the sampling valve used in the food industry is usually exposed in the air, the valve chamber sterilization and oxygen insulation cannot be guaranteed, and the cleaning operation is complicated, etc., and provides a reasonable structure, easy to use and maintain. Convenient, can not only effectively isolate the sampling valve from the external environment, but also continuously exert the sterilization effect of the built-in sterilizing agent, prevent the growth of microorganisms in the valve cavity, and ensure that the sampling sample is free from contamination.
