Spray sterilizer microwave sterilizer microwave sterilizer is a kind of sterilizer, which is the latest sterilization equipment in recent years and is widely used in food and pharmaceutical industries. Microwave sterilization is an efficient, energy-saving, stable, reliable, simple equipment, convenient operation and new technology. The microwave sterilizer is characterized by continuous production of equipment, which only needs electricity and no other energy, and can quickly kill bacteria in materials. The equipment occupies a small area, is pollution-free and is simple to operate. There is no need for preheating and there is no energy loss after shutdown. Less labor and high product quality. The advanced equipment is a high-tech product that can't be replaced by other equipment. Microwave sterilization is the result of the interaction of thermal effect and biological effect of electromagnetic field. The thermal effect of microwave on bacteria is to denature protein, so that bacteria lose nutrition, reproduction and survival conditions and die. The biological effect of microwave on bacteria is that microwave electric field changes the permeability of cell membrane section, so bacteria are malnourished, unable to metabolize normally, their structure and function are disordered, their growth and development are inhibited and they die. In addition, nucleic acid (RNA) and deoxyribonucleic acid (DNA), which determine the normal growth and stable genetic reproduction of bacteria, are relaxed, broken and recombined by several hydrogen bonds, thus inducing genetic mutation, chromosome aberration or even breakage. Main technical parameters of microwave sterilizer: 1. Working voltage of equipment: three-phase 38V±1% 2. Working frequency of microwave: 245MHz±5Hz 3. Input apparent power: ≤48KVA 4. Microwave output power: ≥3KW (adjustable) 5. Transmission mode and speed: variable frequency speed regulation (.5 ~ 5m/min) 6. Microwave. 9. It is mainly used for powdery, granular, flaky or colloidal foods, medicines, agricultural and sideline products, additives, condiments, Chinese herbal medicine materials and other products that need sterilization, mildew prevention and preservation. Specific products are: cake sterilization equipment, moon cake sterilization equipment, etc. PU value sterilizer is one of the key hosts in beer packaging production line. Its main task is to kill yeasts and other miscellaneous bacteria remaining in liquor, ensure the biological stability of beer and make it beneficial to long-term preservation. Usually, the depth of sterilization is expressed by the number of PU (that is, Pasteur sterilization unit, where the sterilization effect caused by one minute at 6°C is 1 PU). Insufficient or excessive will affect the shelf life and flavor of beer respectively, so controlling PU value in a certain range is the main technical index of the sterilizer. In this system, the PU value is related to the parameters such as spray water temperature and running time. The operator only needs to input the required PU value, and the computer will automatically control the spray water temperature in each temperature zone and display the PU value reached by each row of beer in the sterilizer. In addition, the system also has the function of automatically selecting parameters during shutdown. With the length of shutdown time, the temperature of each temperature zone is automatically adjusted to ensure that the PU value is controlled within a certain range. At the same time, the system also has the functions of working state monitoring, fault diagnosis and management, and it is an intelligent "fool" control system. System composition This system is an electro-pneumatic hybrid automatic temperature control system, which consists of a temperature primary sensing element (platinum thermal resistor Pt1), an integrated temperature transmitter, a lower computer (programmable controller), an upper computer, an electromagnetic valve, a pneumatic diaphragm valve, a printer, a compressed air filter and pressure reducing valve, a pressure transmitter, a gas path, etc. Working principle: The temperature of each temperature zone is converted into 4-2mA signals by Pt1 platinum thermal resistor and temperature transmitter, and sent to the programmable controller. The water pump pressure in each temperature zone enters the pressure transmitter through distributor and solenoid valve and is converted into 4-2mA signals, which are collected by the programmable controller in sequence. On the one hand, the programmable controller carries out input and output data processing and PID operation, on the other hand, it transmits various signals to the upper computer. As a man-machine interface, the upper computer can monitor the operation status and various parameters of sterilization process in real time, provide alarms, historical trend charts and data file reports, and the operator can set the PU value, and the computer can calculate the set values of spray water temperature in each temperature zone accordingly. After the input temperature signal is PID-operated, the programmable controller outputs a standard electric control signal (-24VDC) to the solenoid valve, which converts the electric control signal (-24VDC) into a pneumatic control signal (2-1KPa). Finally, the pneumatic membrane valve performs automatic adjustment to control the cooling water or the steam passing through the heat exchanger, so as to control the temperature of each temperature zone. In the programmable controller, the output signals of each temperature zone are linked with the water pump, that is, only when the water pump works and the relay is closed, the pneumatic diaphragm valve can perform automatic adjustment, otherwise, the regulating valve will automatically close. In addition, for the sterilization constant temperature zone and the highest temperature zone, if a link in the production line breaks down and the bottle conveying mechanism stops working, the system will automatically adjust the temperature setting according to the length of downtime to ensure the sterilization quality. When the water temperature in the high temperature area of the sterilizer is higher or lower than the set value of 2 C, and the temperature in the sterilization constant temperature area is lower than the set value of 2 C, the upper computer will pop up an alarm screen to remind the operator to pay attention. The monitoring function (1) sets the PU value and displays the PU value of each row of beer in the sterilizer in real time. (2) Real-time display of the temperature set value and measured value of each temperature zone. When the temperature is too high or too low, an alarm screen will pop up. (3) Real-time display of the pressure value of the water pump in each temperature zone. When the pressure is insufficient, an alarm screen will pop up. (4) Indicate the switch state of each control valve. (5) Manually control the on-off state of the regulating valve. (6) Historical trend chart display. (7) Select the upper computer or lower computer for PID operation.
