UHTS – Sterilizers UHT
UHTS – Sterilizers UHT

UHT stands for ultra high temperatures, sterilization is a process with the purpose to reduce the bacterial load through a treatment at high temperatures maintained for short periods of time.

Managed by PLC on HMI with 12 “color touch-screen LCD screen from which it is possible to check the status of the valves, the status of the pumps, the percentage of opening of the modulating valves, the temperatures, the pressures in real time on P&ID. instantaneous flow rate, processed product volumes, tank level, plc status, etc. 10 production recipes are available. In each recipe it is possible to set the temperatures, the instant flow rate, manage any bypass (optional), alarms and many other parameters.

The operator has the possibility of configuring the sterilizer in sanitizing with hot water in recirculation, in temperature stabilization before production, in production with automatic request of the product, at the end of production with total emptying of the product, in cooling / shutdown and in wash.

The end-of-production sequence provides for total emptying by pushing with water, designed to reduce product losses to a minimum. 1 washing recipe is available (remotely). 

In each recipe it is possible to set the temperatures, the instant flow rate and manage any bypass. Furthermore the system can be controlled in “manual / semi-automatic” mode, in which the operator can force / activate / deactivate / modify the P&ID components.

This mode is mainly used to act as appropriate in the event of unforeseen events but allows an experienced operator to conduct completely independently of automation.

Moreover with the following features:

  • U.H.T. (ultra high temperature) sterilizer with indirect exchange steam/water/product
  • Sterilization stage with multi-tubes heat exchanger.
  • Water/product recovery >76%
  • Digital recording and automatic adjusting of sterilization temperature
  • Digital recording and automatic adjusting of outlet temperature, cooling
  • Digital recording of pressure and automatic adjusting of back-pressure
  • Digital recording and automatic adjusting of flow
  • Automatic leel on tank, with remote pump control
