1. system overview
Automatic tube type ultra high temperature sterilization system (UHT) for automatic control system, give full consideration to the impact of external factors on sterilization temperature, high precision products / water temperature control, ensure the equipment operation and process indicators, material quality and low acid products for no danger of anything going wrong; the filling process requirements, the system is equipped with a hot water pre sterilization system closed, sterilization and efficient and reliable, and effective use of heat, will drop to low energy consumption. At the same time; intelligent PLC control, without manual operation and monitoring complex; CIP system design and production, meet the cleaning production equipment and sterilization requirements.
Automatic tube type UHT sterilization system products in a completely closed system for instantaneous rapid heating and cooling treatment to the flavor and nutrition effect is few, and prevent pollution two products. Products from closed balanced tank pump, ultra high temperature sterilization, after cooling to the filling temperature, and can be directly connected with any filling machine, filling work. The material is sterilized and heated by heating. The hot water is used as the medium, and the temperature of the outlet is adjusted. The cooling water is used as the medium, and the temperature control precision is high. All programs can be set according to the actual process requirements in advance. Only the manual instructions are given on the touch screen, and the automatic tube type ultra high temperature instantaneous sterilization system can perform corresponding operations in sequence according to the preset procedures.
The key components of automatic tube type ultra high temperature sterilization system use the world famous manufacturers of professional products. ,
2. main features
(1) the main accessories of temperature inspection system are sanitary products from Denmark TEMPRESS company;
(2) the flow meter selects Danfoss company's hygienic products;
(3) steam pipes and valves are made of SPIRAX SARCO products;
(4) control components and touch screen adopt SIEMENS products;
(5) PLC uses SIEMENS products;
(6) pneumatic components using SMC products;
(7) the whole set of UHT sterilization system adopts man-machine interface and PLC centralized control, and is equipped with touch screen. On the touch screen, each display unit can display, prompt and confirm the frame when it is running, completed and converted. It is easy to operate, and the operator can control and monitor the working conditions of the whole system online. The touch screen has system control, temperature point detection, continuous curve display, and can be sent to a paper recorder (optional parts) output, the product quality control online control and long-term tracking;
(8) UHT sterilization system is aseptic configuration, to prevent unexpected fluctuations of external conditions, resulting in the two pollution of the product, and thus ensure the stable operation of the whole set of filling production line.
3. automatic pipe type ultra high temperature instantaneous sterilization system parameter control and adjustment
(1) and the control temperature sterilization: sterilization of this set of equipment is suitable for the sterilization temperature are less than 137,. Sterilization temperature can be set according to requirement. The equipment can be automatically controlled by the PLC according to the set temperature, and the corresponding components are automatically adjusted so that the sterilization temperature is stable at the set point and the control accuracy is maintained. Through intelligent monitoring, the material that can not reach the temperature of sterilization is automatically circulated back and forth, thus avoiding the pollution of the unqualified material to the aseptic section of the equipment, and providing corresponding signal alarm at the same time.
(2) discharge regulation and control temperature: the discharge temperature should be applicable to a range of 65~92 DEG C. The outlet temperature can be set according to the demand. The equipment can be automatically controlled by the PLC according to the set temperature, and the corresponding components are automatically adjusted so that the outlet temperature is stable at the set point and the control accuracy is kept high.
(3) the regulation and control of UHT flow: flowmeter indicator values for reference, artificial regulation of UHT flow control valve to meet the requirements of export.
