Tubular UHT equipment overview
After deployment of the juice drink before filling the need for sterilization , thermal sterilization is the most common process . Depending on the product features and different filling process and the subsequent matching shelf life , you can choose UHT (UHT) sterilization or high temperature short time (HTST).
UHT 137 ℃ normally more than several seconds , and is a typical process HTST 95 ℃ for 30 seconds. Regardless of the process , both the structure and working principle is similar , both heating and temperature hold.
The form of the heat exchanger plate type, tube type , bellows and the like. With pulp -containing particles or high viscosity products , tubular heat exchanger must be used to prevent clogging. Meanwhile tube heat exchanger pressure capability but are more expensive to make than a plate heat exchanger .
For cloudy juice or milk juice drinks , we recommend tube UHT; For juice drinks , can be plate heat exchanger models.
The main components of UHT / HTST unit : Steam heating unit ( heat exchangers and steam valve ) , hot water unit ( water tank ) , a multi-stage heat exchanger, the holding tube , product pumps, heat pumps , balance cans, pipe racks and so on.
Plate UHT equipment overview
Plate UHT PLC automatic control system is intelligent , yield 3-20 tons / hour are available. For drinks low, medium temperature , high temperature, hot filling process requirements , the system will work plate segment is divided into sterile working segment and general working segment , seven segment heat exchanger unit selection process design , effective use of heat, the energy consumption minimize perfect CIP and SIP systems designed to meet the cleaning and sterilization equipment requirements. Sterilization temperature and adjust the material filling the heating outlet temperature of hot water are used as medium , high precision temperature control .
This set of automatic plate UHT system , the key components are made of world famous manufacturers : ALFALAVAL, APV, SPIRAX, SARCO, SIEMENS, FESTO and other products.
