Pasteurization device

Abstract

The invention discloses a pasteurization device. The pasteurization device comprises a heating sterilization cavity and a cooling and temperature reducing cavity, wherein a helical material pipeline is arranged in the heating sterilization cavity, and a cavity body of the heating sterilization cavity is connected with a hot water circulating unit and a steam inlet and outlet pipeline; and a helical temperature-reducing material pipeline is arranged in the cooling and temperature reducing cavity, and a cavity body of the cooling and temperature reducing cavity is connected with a cold water circulating unit. According to the pasteurization device disclosed by the invention, materials are heated and sterilized through hot water and steam, and the temperature of sterilized materials is reduced through cold water; steam impurities can be filtered through a steam filter, so that the steam impurities can be prevented from polluting the materials; sterile air blows and sweeps sterilized condensed water through a sterile air filter, so that the condensed water is prevented from polluting the materials; the flow speed of the materials is adjusted, the length of the spiral pipeline is adjusted, and the temperature of a sterilization device is controlled, so that sterilization of 75-121 DEG C is realized, and the sterilization time lasts for several seconds to tens of seconds. According to the pasteurization device disclosed by the invention, after heating, temperature reduction is rapidly performed, so that influence on the nutrients and the appearance caused by the situation that the materials are under the high-temperature state for a long term can be avoided, and the pasteurization device is simple and convenient to use.

Description

technical field [0001] The invention relates to a simple and convenient pasteurization device, which can realize the sterilization and rapid cooling of materials, and can be applied to the fields of food processing and cosmetics, especially the production of milk and fruit juice in food processing. Background technique [0002] Pasteurization is a sterilization method widely used in the production of food, cosmetics, and even pharmaceuticals. The main principle is the mechanism that harmful microorganisms cannot tolerate high temperature. Its main feature is to keep it at a lower temperature (60-65°C) for 20-30 minutes, or at a higher temperature (75-95°C) for more than ten seconds to tens of seconds. It can not only ensure the killing of harmful microorganisms, but also extremely avoid the damage of high temperature to the nutrition and activity of sterilized materials. [0003] After investigation, the existing sterilization device mainly heats and sterilizes the materia...
