Spray sterilizer Microwave sterilizer Microwave sterilizer is a type of sterilizer. It is the latest sterilization equipment developed in recent years and is widely used in the food and pharmaceutical industries.
Microwave sterilization is a new technology that is efficient, energy-saving, stable, reliable, simple in equipment, easy to operate. The characteristic of the microwave sterilizer is that the equipment produces continuously, only requires electricity and does not require other energy sources. It can quickly kill bacteria in the materials. The equipment occupies a small area, is pollution-free, and is simple to operate. It does not require preheating and does not shut down. Finally there is energy loss. Less labor and high product quality. The equipment is highly advanced and is a high-tech product that cannot be replaced by other equipment. Microwave sterilization is the result of the simultaneous action of the thermal effect and biological effect of the electromagnetic field. The thermal effect of microwave on bacteria is to denature proteins, causing bacteria to lose nutrition, reproduction and survival conditions and die. The biological effect of microwaves on bacteria is that the microwave electric field changes the permeability of the cross-section of the cell membrane. As a result, the bacteria are malnourished and cannot metabolize normally. The structure and function of the bacteria are disordered, and their growth and development are inhibited and they die. In addition, the nucleic acid (RNA) and deoxyribonucleic acid (DNA) that determine the normal growth and stable genetic reproduction of bacteria are caused by the relaxation, breakage and recombination of several hydrogen bonds, thereby inducing genetic mutations, or chromosome aberrations, or even breakage. Main technical parameters of microwave sterilizer: 1. Equipment working voltage: three-phase 380V±10 2. Microwave working frequency: 2450MHz±50Hz 3. Input apparent power: ≤48KVA 4. Microwave output power: ≥30KW (adjustable) 5. Transmission method and speed: variable frequency speed regulation (0.5~5m/min) 6. Microwave leakage: in line with the national GB10436-89 standard 7. Equipment working environment: 5~40℃, relative humidity ≤80 8. Control: ordinary control or PLC man-machine Interface control. 9. Mainly used for powdery, granular, flake or colloid-like food, medicine, agricultural and sideline special products, additives, condiments, Chinese herbal materials and other products that require sterilization, mildew prevention and preservation. Specific products include: pastry sterilization equipment, moon cake sterilization equipment, etc. PU value The sterilizer is one of the key hosts on the beer packaging production line. Its main task is to kill yeast and other miscellaneous bacteria remaining in the wine liquid to ensure the biological stability of the beer and make it conducive to long-term storage. The depth of sterilization is usually expressed by the PU value (i.e. Pasteur sterilization unit, the sterilization effect caused by 1 minute at 60°C is 1 PU value). Insufficient or excessive will have an impact on the shelf life and flavor of beer respectively, so controlling the PU value within a certain range is the main technical indicator of the sterilizer. The system links the PU value with 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 each parameter in the sterilizer. The PU value achieved by discharging beer. In addition, this system also has the function of automatically selecting parameters during shutdown. With the length of shutdown time, it automatically adjusts the temperature of each temperature zone to ensure that the PU value is controlled within a certain range. At the same time, this system also has functions such as working status monitoring, fault diagnosis and management, and is an intelligent "fool" control system. System components: This system is an electric-gas hybrid temperature automatic control system, which consists of a temperature primary sensing element (platinum thermal resistance Pt100), an integrated temperature transmitter, a lower computer (programmable controller), a host computer, and a solenoid valve. , pneumatic membrane valve, printer, compressed air filter pressure reducing valve, pressure transmitter, gas circuit, etc. Working Principle: The temperature of each temperature zone is converted into a 4-20mA signal by a Pt100 platinum thermal resistor and a temperature transmitter and sent to the programmable controller. The water pump pressure in each temperature zone enters the pressure transmitter through the distributor and solenoid valve and is converted to 4-20mA. After receiving the signal, it is collected sequentially by the programmable controller. On the one hand, the programmable controller performs input and output data processing and PID calculations, and on the other hand, it transmits various signals to the host computer. As a human-machine interface, the host computer can monitor the operating status and various parameters of the 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 calculates the spraying of each temperature zone accordingly. Water temperature set value.
After the input temperature signal is calculated by PID, the programmable controller outputs a standard electrical control signal (0-24VDC) to the solenoid valve. The solenoid valve converts the electrical control signal (0-24VDC) into a pneumatic control signal (20-100KPa). Finally The pneumatic diaphragm valve performs automatic adjustment to control the amount of cooling water or steam passing through the heat exchanger so that the temperature of each temperature zone is controlled. In the programmable controller, the output signal of each temperature zone is linked to the water pump. That is, only when the water pump is working and the relay is closed, the pneumatic membrane 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 certain link in the production line fails and the bottle transport mechanism stops working, the system will automatically adjust the temperature setting value according to the length of the downtime to ensure sterilization quality. When the water temperature in the high-temperature zone of the sterilizer is 2°C higher or lower than the set value, and the temperature in the sterilization constant temperature zone is 2°C lower than the set value, the host computer will pop up an alarm screen to remind the operator to pay attention. Monitoring function (1) Set the PU value and display the PU value achieved by each row of beer in the sterilizer in real time. (2) Display the temperature setting value and measured value of each temperature zone in real time. When the temperature is too high or too low, an alarm screen will pop up. (3) Display the pressure value of the water pump in each temperature zone in real time. When the pressure is insufficient, an alarm screen will pop up. (4) Indicate the switching status of each regulating valve. (5) Manually control the switching status of the regulating valve. (6) Historical trend graph display. (7) Choose whether the upper computer or the lower computer performs PID operation.
