Most of the fermenters for modern fine brewing are conical tanks, but historically, they have undergone many evolutions, and of course it is also related to the process and cooling conditions used, and some are still in use today.

What is a fermenter?

Fermentation tank: It used to be the place where the pre-fermentation process of the big brewery was completed. Now it is almost useless. Now it is mostly used to brew traditional Belgian Lambics beer, which is made of local wild yeast and floating in Airborne fungi ferment the beer instead of using cultured yeast. It is usually made by mixing wheat, barley malt, hops, exposing to cold air, and then storing in oak barrels for more than three years. These microbes in the air make the beer taste acidic, and there are other striking aromas such as leather, this non-mainstream and sharp taste is often addictive.

This fermentation method is still used among the very few users of craft beer equipment. A fermentation tank is made of stainless steel plates, with legs above the ground, placed in a ventilated and temperature-friendly room, and naturally cooled with wort.

What is a front fermenter?

Front fermenter: Usually cylindrical, with a flat and inclined bottom, a double-layer atmospheric pressure container with polyurethane insulation, and a Maitreya cooling jacket on the outside of the inner tank. Ice water circulation can be used to take away the heat generated by fermentation. There is a lift on the top The stainless steel flat cover with power assist can effectively ensure the ingress of miscellaneous bacteria, and it can be easily lifted to facilitate the cleaning of the bubble cover produced by fermentation and the dead yeast, hop grains, and wort thermal coagulation left by pouring the tank; the lower flat bottom A slight slope is convenient for draining the last drop; the temperature can be automatically controlled and very precise, which is conducive to the realization of the fermentation process.

What is a post-fermentation tank?

Post-fermentation tank: it is commonly referred to as a fermentation tank. The overall material is generally SUS304 stainless steel, which is welded by argon arc, and the interior is polished or pickled and passivated;

Due to the need of pressure, the upper part of the structural design is a head or cone, and the lower part of the taper is designed to facilitate the discharge of yeast. The normal design is 60°, and sometimes there are 72°, 75°, and 90° in order to reduce the height. The larger the angle is, the yeast The more difficult it is to row.

In addition to the manhole door and butterfly valve, the accessories on the fermentation tank also include positive and negative pressure safety valves, mechanical pressure regulating valves, sampling valves, rotary wine outlet valves, pressure gauges, bimetallic thermometers and titanium rods for carbon dioxide charging.

What is the function of the positive and negative pressure safety valve?

Positive and negative pressure safety valves are the last line of defense for the safety of fermentation tanks. Both positive pressure, overpressure and negative pressure are opened, especially if the negative pressure is very low, the tank may be sucked. This valve is installed separately, and there are also mechanical pressure valves. The regulating valve is combined into one, installed on the CIP cleaning pipe, and also has the function of positive and negative pressure protection; the mechanical pressure regulating valve is used to keep the pressure in the tank constant, and the high-end point is the water-sealed mechanical pressure regulating valve. There is a transparent water-sealed cup, you can see the bubbles coming out, which is more intuitive.

What kind of sampling valve is better?

The best sampling valve should be the one with a screw cap on the upper part. Although it is a little expensive, it has good sealing performance and is not easy to be damaged, and there is also an interface that can be installed with a spiral defoamer; the side handle is not tightly sealed, and the front handle is occasionally The pad is damaged, although it is not a big problem, it is considered a defect.

Pressure gauges and bimetallic thermometers are generally fine. It is best to choose shockproof pressure gauges; bimetallic thermometers are irrelevant, just to check the temperature in general. The temperature control in the tank is realized by more accurate temperature sensors and temperature controllers. Yes, with a little decorative property.
