Wort Cooling & Aeration

Heat exchanger described here is most currently applied size for microbreweries, for pubbreweries see one-stage interchanger (point B).

A) MICROBREWERY SYSTEMS (Eurotech-CLASSIC):

WORT-COOLER: two-stage stainless-steel plate heat exchanger
Specification:
Length .................................................................... 1 695 mm
Width ......................................................................... 320 mm
Height ........................................................................ 960 mm
Parameters:
Wort temperature .................................................... 98°C/25°C/6°C
Water temperature...................................... 22°C/82,3°C; 2°C/15,5°C
Wort flow-through ...................................................... 100 hl/hr
Number of plates ......................................................... 198 pcs
Weight ......................................................................... 328 kg

By wort cooling, cold water is warmed up to 82,3°C and is stored in Hot Water Tank.
In relation to wort outgoing temperature, wort flow-through rate is controlled by frequency changer equipped pump.

STERILE WORT AERATION: (prior to transfer to fermenters)
Equipment: rough oil-removing filter, cooler-drying oven, fine oil-removing filter, very fine oil-removing filter for oily smells and steams capture, sterile filter, aeration-candle, compressor

B) PUBBREWERY SYSTEMS (Eurotech-CLASSIC):

Cooling takes place in one-stage heat-exchanger equipped with in-line sintered stainless tube. Hot wort (96°C) is pumped from the mash tank to this multi-pass plate heat exchanger where cold water (2°C), pumped from cold liquor (water) tank, cools wort down.
By wort cooling, cold water is warmed up to 85°C and is stored in the bottom unit of Combi-Tank that serves as Hot Water Tank.
STERILE WORT AERATION:
Wort cooled down to 6-8°C is aerated by sterile air through sintered tube placed in the heat-exchanger outlet pipe and then transferred to fermenting tanks.
In relation to wort outgoing temperature, wort flow-through rate is controlled by frequency changer equipped pump.
