The importance of the cooling and glycol systems in your craft brewery-Part 1



Your air conditioning as well as glycol systems, much better understood as a refrigerator, is the most vital item of devices in your brewery. While milling, mashing, lautering, as well as steaming are tough ideas to link with the refrigerator system, the warmth included throughout these procedures is eliminated by the refrigerator.

Allow's analyze the actions of the beer making procedure to see just how glycol is made use of along the road.

Wort Refrigerators as well as Glycol
1. Cold Alcohol Storage Tank (CLT) and also a Single-Stage Wort Warm Exchanger
The CLT is usually a stainless steel water storage tank with air conditioning coats or an exterior warm exchanger. The CLT is loaded with water that is cooled in between developing cycles to a temperature level around 35 F. This chilly water is after that pumped via the wort exchanger at a 1:1 proportion, cooling down the wort from article boil temperature level to the wanted fermentation temperature level.

2. Two-Stage Air conditioning making use of City Water as well as Chilled Glycol
Two-stage wort exchanger cools down the wort in 2 actions:

Action 1 makes use of city water at a 1:1 proportion, eliminating as much warm as feasible. Relying on warmth exchanger performance, wort will certainly leave the initial stage within 7-10 F of your going into water temperature level.

Action 2 transfers the staying warm to cooled glycol as well as leaves at wanted fermentation temperature level.

Quick reality: this warmth tons is remarkable when contrasted to the various other cooling down lots the refrigerator system solutions. Typically this will certainly call for the maker to separate their storage from the air conditioning loophole, so every one of the offered air conditioning capability of the refrigerator system is devoted to this solitary procedure.

3. Pre-chill the City Water Before Getting In the Single-Stage Wort Warm Exchanger
This is a terrific reduced expense choice for breweries that experience a seasonal spike in city water temperature levels, however the remainder of the year have the ability to sufficiently cool down the wort. A reduced price brazed plate stainless-steel warmth exchanger is utilized with the downside that these bonded warm exchangers can not be opened approximately tidy and also if they come to be fouled or connected, commonly a brand-new warm exchanger is required.

4. Using a Three-Section Warm Exchanger
This 4th situation is in fact a mix of alternatives 2 and also 3. Using a three-section warm exchanger, or numerous specific warm exchangers, that make use of a mix of chilly alcohol, cooled glycol, and also city water to cool down the wort. These are commonly located at breweries that make a great deal as well as have actually just expanded past the developed ability of the brewhouse.

Choosing which choice is ideal relies on numerous elements: ordinary supply of water temperature level, your mixture routine, the designs of beers that you make, and also your future development strategies. I would certainly recommend speaking with various other makers in your dimension array and also in your area. Inquire from your refrigerator distributor, they will certainly rejoice to assist examine the alternatives with you.

Your air conditioning as well as glycol systems, much better recognized as a refrigerator, is the most vital item of devices in your brewery. While milling, mashing, lautering, and also steaming are difficult principles to link with the refrigerator system, the warmth included throughout these procedures is gotten rid of by the refrigerator. One of my favored examples is: "The Central heating boiler is the gas pedal and also the refrigerator system is the brakes."

The usage of a three-section warmth exchanger, or numerous specific warmth exchangers, that make use of a mix of chilly alcohol, cooled glycol, and also city water to cool down the wort. Look for recommendations from your refrigerator vendor, they will certainly be happy to assist review the choices with you.
