In breweries the plate heat exchanger has been used as standard technical
equipment since the introduction of the closed wort routing (a successor
of the surface irrigation cooler). Over the years the applications
have grown extensively.
Plate heat exchangers are also employed today in breweries for exhaust vapor
condensation, yeast cooling, beer deep-freezing, heating of CIP solutions and
other thermal procedures.
A classical example of the use of the plate heat exchanger is short-term heating
for the thermal stabilization of beer and non-alcoholic drinks.

Typical tasks for SIGMA plate heat exchanger in the brewing industry are:
- Cooling and heating of wort
- Cooling of yeast
- Exhaust vapor condensers
- Cooling of condensate
- Hot water boiler
- CIP heater
- De-alcoholization plants
- Concentrate systems for yeast, malt extract and wort

Application example: WORT COOLING
Since the company foundation in 1879, wort cooling has been represented
in the standard program of API Schmidt-Bretten. SIGMATHERM wort
coolers can be adapted to the respective requirements of mashing liquor:
Traditionally they find application in two-stage implementation or, in accordance
with more modern technology, in one-stage implementation with a stacking tank
for precooled mashing liquor. The wort aeration is combined in practice with
the wort cooling. Exactly-metered air dosing and the finest distribution in the
wort guarantee good cold sludge flotation, sufficient oxygen supply of the yeast,
and homogeneity of the setting wort.
Application example: WORT HEATER (external cooker)
The purified wort is no longer heated in the pan, as in the pasr, rather
it is heated up from the supply flow container over the plate heat
exchanger with 8x to 10x the quantity of the pan content. According to
system, the wort is heated up from 72/74°C to 98/99°C with water
at 101/104°C,
so that water at 78/80°C results. This water is stored and employed
for sparging for the next broth. |
