Brewing lagers, ales, ales, stouts, and IPAs requires a carefully designed fermentation environment, regardless of scale. The fermentation stage is particularly crucial to the final result of the blend, and cooling the blend using external brewery fermenter head cooling is an effective way to maintain optimal fermentation temperatures. To prevent the fermentation mix from being exposed to undesirable temperatures, brewers often attempt to cool the entire process. For breweries producing beverages on a large scale, the most effective way to ensure optimal temperature regulation is to use a fermentation cooling jacket in combination with a brewery chiller or a winery glycol chiller.
A honeycomb sandwich panel is made by punching two stainless steel sheets and bonding them to a thicker honeycomb core. This is also known as a honeycomb sandwich structure. It offers advantages such as light weight, excellent sound insulation, and high elasticity.
A fermenter/brewery tank cooling jacket is a temperature regulation technology that allows beer to be cooled externally. A standard beer tank cooling jacket is made of a flexible material with a cavity through which a coolant (typically a mixture of ethylene glycol and water) flows. When the glycol cooling jacket is wrapped around a brewery or beer tank, it absorbs heat from within the tank.
Fermenter cooling jackets are made of flexible material with coolant channels running through them. When the jacket is wrapped around the brewing vat, the coolant flowing within the jacket's channels absorbs heat from the brewing liquid through a simple heat exchange process.
Adjustable temperature levels allow for more uniform cooling and fermentation.
Because the integrity of the tank is not compromised, accidental contamination is prevented.
Easy to install and maintain.
Fermenter cooling jackets are a crucial component of the overall brewery cooling system. Industrial chillers help re-cool the heated coolant returning from the fermenter jacket, preparing it for recirculation. The chiller maintains the coolant at the optimal temperature for wine or beer fermentation.
Each yeast strain has its preferred operating temperature for maximum yield. For example, Saccharomyces cerevisiae (the most common yeast strain) prefers a temperature between 30°C (86°F) and 45°C (113°F). Temperatures that are too high or too low can inhibit productivity. Therefore, managing fermentation temperature is crucial to maintaining optimal production time and yield.
The fermentation cooling jacket is a sheath surrounding the main vessel. The fermenter cooling jacket acts like another water tank, surrounding the inner walls of the fermenter. The cooling jacket has inlets and outlets to circulate a cooling medium. The flow rate of the cooling medium can be used to control the fermentation temperature. As the name suggests, a jacket is a heat exchanger that transfers heat between two fluids: one is the cooling medium, and the other is the fermenting beer or wine.
Brewing perfect-tasting beer requires consideration of several factors. One of the most important is maintaining the ideal temperature during fermentation. Maintaining temperature is absolutely crucial, as if the wort temperature is too high, the beer may develop a fruity flavor. If the fermenter temperature is lower than expected, the beer may not ferment properly, affecting its quality and flavor. Typical wine fermentation temperatures range from 40°F (about 4°C) to 80°F (about 24°C). In large fermenters, maintaining brewing conditions within this narrow range is often difficult using simple cooling fans and thermostats. In these situations, temperature-controlled fermenters are a better choice.
Fermentation tanks can be cooled using cooling devices immersed in the fermentation liquid or using fermentation tank cooling jackets.
In some cases, cooling rods or coils can be introduced into the brew to maintain the desired temperature. While this technology is inexpensive and easy to install, it also has significant disadvantages.
First, using immersion coolers or plate coolers in fermenting wine increases the beer's exposure to microorganisms and accelerates oxidation, which can alter its flavor. Furthermore, internal cooling reduces cooling efficiency. Uneven cooling of the fermentation tank can lead to hot and cold spots, resulting in uneven fermentation.
Cooling your beer using an external fermenter jacket is an effective way to maintain optimal brewing temperature. External brew jackets provide even cooling without exposing the liquid inside to microbial contamination and unwanted oxidation.
As the name suggests, this immersion cooling method requires only a large bucket filled with ice, or better yet, a frozen water bottle. Water bottles stay frozen longer, which is a definite bonus while you're waiting for the fermentation process to complete, which can take at least two weeks.
In most cases, a mixture of ethylene glycol and water (30% ethylene glycol solution) is the optimal coolant for wine tank cooling jackets. Here are some key advantages of using ethylene glycol as a coolant:
Ethylene glycol retains heat longer than water, improving efficiency.
It provides greater lubrication for the chiller pump.
Ethylene glycol has antifreeze properties, allowing it to cool to sub-zero temperatures without freezing and clogging the chiller pipes.
DEGONG utilizes two-stage cooling with a dimpled jacket, a conical bottom, and straight walls. The punching distance and arc of the dimpled jacket are designed based on the tank's pressure requirements and in accordance with the drawings. The Miller panel has a consistent honeycomb shape, ensuring adequate stress resistance during tank pressure holding. This ensures a long service life and high pressure-bearing capacity.
