PASTEURISER DESCRIPTION:

A three-section plate heat exchanger (made by SCHMIDT, Germany); a tubular keeper; a multigrade, centrifugal pump of high pressure (made in Italy or in Spain)

A heating system containing a steam-water plate heat exchanger (made in Sweden); a centrifugal pump; an electro pneumatic regulation valve (made by Burkert, Germany); a condensate-trap; a controlling regulatory equipment.

A cooling system containing an electro pneumatic regulation valve (made by Burkert, Germany); controlling regulatory equipment.

A control box containing a temperature control equipment (thermo-regulators), as well as buttons to switch on the sensors. Alarm lamps are also included.

Frames, tubular fittings and butterfly manual taps by (AWH, Germany or SODIME, France).

All these systems are installed on one big frame.

After launching the equipment, the set in advance temperature is kept during the whole process of beer pasteurizing. Tap opening and closing is done manually by the operator. In order to preserve the heat exchanger from pressure excess, the pasteurizer is equipped with a pressure relay in addition to an emergency valve and a pneumatic actuator. The pumps are protected with quantity sensors, so whenever the liquid is absent, the pump switch off and the operator is notified about it with the help of the alarm lamps in the control box. If there is no enough air in the machine, it doesn’t launch the process, and the operator is notified about it with the help of the alarm lamps in the control box.

Three-plate heat exchanger consists of pressure plates bearing shaft and clamping screws made of stainless steel AISI 304. intermediate plates exchanger made of stainless steel AISI 316L (steel production in Sweden or Italy).

The tubular fittings and the butterfly manual taps are made of stainless steel AISI 304 or AISI 316L

The tubular keeper is made of tubes (material AISI 304) with a total length provides the performance 50 hl / h and exposure time of 30 seconds.

1.8.1 BUFFER TANK

The buffer tank has a volume of 2,500 litres and working pressure of 3 atm.

The buffer tank consists of:

• a washing head
• a level sensor (3pcs)
• a return pump CIP from the buffer tank with a sensor of liquid quantity
• a valve for remaining pressure
• a vacuum valve
• a CO2 reducer and return valve
