The structure and working principle of the laboratory micro-super high temperature sterilization machine is revealed!

The laboratory micro-ultrasonic sterilization machine is a tube-type sterilizer specially designed for the acquisition of test data by the research and development institutions of the laboratories and production units of various universities and colleges. It integrates heating, sterilization, cooling and heat recovery into one, fully simulating production. The actual production status of the workshop, which truly reflects the production data in the laboratory. The touch screen and PLC program control are configured to dynamically reflect various parameters such as temperature and flow of the product. The operation is simple and flexible, with CIP cleaning function, high temperature alarm of return valve action, and low temperature reflow (automatic). Optional homogenizer, aseptic filling room, etc.

The laboratory micro-ultra-high temperature sterilization machine is generally preheated by centrifugal pump pumping into the hot and cold material heat exchange device in the sterilization machine, and then passed through a high-pressure high-temperature barrel, the material is rapidly heated to the sterilization temperature and maintained before and after. About 3 seconds, the microbes and enzymes were quickly killed. After the material exits the high temperature barrel, it is cooled by heat exchange with the cold material, and the temperature is generally lower than 65 °C. If the next process needs to increase the temperature, it can be achieved by adjusting the angle cut-off valve or circulation, etc., otherwise the cooling water is added to reduce the discharge temperature. The discharge is controlled by a throttle valve which enables the boiling point of the material to be higher than the high temperature while maintaining a certain pressure. This valve is adjusted during normal production, and the back pressure control flow is generated by the pump's urging force against the spring pressure, and should be fully opened during cleaning. The circulating storage tank can be used to prepare an acid-base solution for effective cleaning of the inner wall of the coil. The laboratory micro-ultrasonic sterilizer can be properly adjusted due to the simultaneous use of stainless steel three-way cocks.

The structure and working principle of the laboratory micro-super high temperature sterilization machine:

The main engine is equipped with a pressure vessel - a high temperature bucket for filling pressurized steam. The main arrangement outside the barrel is a spiral double casing, which serves as a heat exchange for the incoming and outgoing materials; a spiral single tube is mainly used in the barrel to receive heat. The sterilization process of the material. The material is preheated by the feed pump entering the outer flow channel of the double set of coils and indirectly heated by the hot material flowing out from the inner layer. When the material enters the high temperature coil disposed in the high temperature barrel, the steam in the barrel is indirectly Heating and heating to the required sterilization temperature, and then in the single coil outside the barrel to keep the material bacteria killed, when returning to the double set of coils, the material enters the inner layer flow channel, the outer layer of cold material Cooling, so that the discharge temperature drops significantly (generally below 65 ° C).

When it is necessary to increase or decrease the discharge temperature in the process, the angle shut-off valve can be activated to turn on the heat source (steam) or the cold source (water or ice water, etc.) to enter the outer flow path at the lower end of the double sleeve. The throttle valve can be adjusted to maintain the material under a certain pressure to increase the boiling temperature to prevent vaporization: on the other hand, the laboratory micro-ultrasonic sterilizer also regulates the flow. The material is removed by a three-way cock. The lower end of the cock is next to the coil, the outlet of which will be the sump, and the coil can be circulated to the overflow tube when needed. The upper end of the feed three-way cock is connected to the sump, and the lower end is connected to the source pipe.
