1. System overview
The automatic tubular ultra-high temperature instantaneous sterilization system (UHT) is fully automatic control. The system fully considers the influence of external factors on the sterilization temperature. The high-precision product/water temperature difference control ensures that the operation of the equipment, process indicators and material quality are foolproof; At the same time, in accordance with the filling process requirements of low-acid products, the system is equipped with a closed superheated pre-sterilization system, which is highly efficient and reliable in sterilization, and effectively uses heat sources to reduce energy consumption to **; at the same time, intelligent PLC control does not require complicated Manual operation and monitoring; CIP system design before and after production to meet the cleaning and sterilization requirements of production equipment.
Automatic tubular ultra-high temperature instantaneous sterilization system The product sterilization is processed in a completely closed system with continuous instantaneous rapid heating and quenching, which has little effect on the flavor and nutritional components of the product, and prevents secondary pollution of the product. The product is pumped in from a closed balance tank for ultra-high temperature sterilization, cooled to the filling temperature, and can be directly connected to any filling machine for filling work. Material sterilization and heating uses superheated water as the medium, and the adjustment of the filling outlet temperature uses cooling water as the medium, with high temperature control accuracy. All programs can be set in advance according to the actual process requirements. Only manual instructions are given on the touch screen, and the automatic tubular ultra-high temperature instantaneous sterilization system can perform corresponding operations in sequence according to the preset program.
The key components of the automatic tubular ultra-high temperature instantaneous sterilization system are selected from professional products of the world's ** manufacturers. ,
2. Main features
(1) The main accessories of the temperature detection system are sanitary products from TEMPRESS, Denmark;
(2) The flowmeter uses Danfoss sanitary products;
(3) The main parts of the steam pipeline and valve are SPIRAX SARCO products;
(4) The control components and touch screen adopt SIEMENS products;
(5) PLC uses SIEMENS products;
(6) Pneumatic components adopt SMC products;
(7) The entire UHT sterilization system adopts human-machine interface and PLC centralized control, equipped with touch screen. The touch screen has display, prompt and confirmation dialog boxes when the respective control units are running, completed, and converted, which is easy to operate, and the operator can control and monitor the working conditions of the entire system online. The touch screen has the continuous curve display of the system's control temperature points detection, and can be sent to the paper recorder (optional part) for output, and online control and long-term tracking of product quality control;
(8) The UHT sterilization system is an aseptic configuration to prevent accidental fluctuations in external conditions from causing secondary pollution of the product, and thereby ensure the stable operation of the entire filling production line.
3. Parameter control and adjustment of automatic tubular ultra-high temperature instantaneous sterilization system
(1) Control and adjustment of sterilization temperature: This set of equipment is suitable for the sterilization of materials whose sterilization temperature is ≤137℃. The sterilization temperature can be set according to requirements. The equipment can be controlled by PLC in a fully automatic manner according to the set temperature, and the corresponding components can be automatically adjusted to stabilize the sterilization temperature at the set value and maintain the control accuracy. Through intelligent monitoring, the material that does not reach the required temperature of sterilization is automatically recirculated to avoid the contamination of the sterile section of the equipment by unqualified materials, and the corresponding signal alarm is provided.
(2) Adjustment and control of the discharge temperature: The discharge temperature should be within the range of 65~92℃. The outlet temperature can be set according to requirements. The equipment can be controlled by PLC in a fully automatic manner according to the set temperature, and the corresponding components can be automatically adjusted to stabilize the outlet temperature at the set value and maintain high control accuracy.
(3) Adjustment and control of UHT flow: take the flow meter indication value as a reference, manually adjust the UHT outlet flow control valve to meet the requirements
