Flash pasteurisers

Automatic variable or fixed flow flash pasteurizers, provided with pasteurized product buffer tank.

Machines designed to pasteurize the product with indirect method, by means of a plate heat exchanger, and to stock the pasteurized product in a dedicated tank before it is used to fill containers.

  • Beer
  • Kvass
  • Tea
  • Completely automatic operation
  • All parameters are constantly controlled
  • Total hygiene and safety
  • Capacity range: from 1.500 L/hour and higher
  • The different parts of the machine are fixed onto a solid stainless steel basement.
  • Product pump assembly, which consists of:
    • High pressure centrifugal pump.
    • Overpressure centrifugal pump.
  • Heat exchanger composed of three sections: regeneration (from 90% to 95%), heating and product final cooling. The AISI 316L steel plates are secured onto an AISI 304 steel structure and fixed by means of lateral tension rods.
  • Tubular holding section, designed to obtain the pasteurization units required, according to the maximum hourly production of the pasteurizer. The holding section assembly is manufactured in AISI 304L.
  • Hot water production system in stainless steel complete with:
    • Manual valve for mains water inlet.
    • Micro-flow modulating valve for steam inlet adjustment.
    • Stainless steel shell and tube heat exchanger.
    • Centrifugal pump for hot water circulation.
    • Temperature transmitter type PT100.

Instrumentation for the pasteurization system:

  • Temperature transmitters type PT100.
  • Graphic display / temperature and P.U. electronic recorder.
  • Set of air-pressure operated valves, 2 or 3 ways on/off provided with position sensor.
  • Pressure gauges and thermometers for the control of circuit pressures and temperatures.
  • Manual butterfly valves, ball valves, solenoid valves and couplings in hygienic materials.
  • Sight glasses and sampling valves.
  • Flow-meter installed at the heat exchanger outlet to control the product flow-rate by means of the relevant modulating valve.
  • Conductivity meter for the alternate succession of product and water.
  • IP54 Stainless steel switchboard, waterproof, provided with operator panel showing PU values, machine status, data, alarms, failures and operation parameter settings.

Product storage tank, made of stainless steel AISI 304, with the following characteristics:

  • Polished both externally and internally.
  • Safety valve.
  • Pressure transducers for electronic control of the level by means of differential pressure analysis.
  • Spray ball for internal cleaning of the tank.
  • CO2 flow regulation system.
  • Hydraulic and electrical connections to the pasteurizer.
  • Test certificate, issued by the Italian authority.
  • Booster pump (which sends the cleaning solution off to the filler).
  • Ultrasonic minimum level sensor.
