Que gamas de tamanhos estão normalmente disponíveis para fermentadores?

Os fermentadores estão disponíveis em diversos tamanhos e formatos para atender às necessidades do cervejeiro. O tamanho é o principal fator a considerar na compra de um fermentador. Durante todo o processo de fermentação, também ao mosto, forma-se uma espessa camada de espuma, denominada espuma Clausen. Se o seu fermentador for muito pequeno, a espuma aumentará através da câmara de descompressão, obstruindo a câmara de descompressão e causando uma explosão. O fermentador deve ser pelo menos vinte por cento maior do que a quantidade de cerveja que você pretende preparar. Depois de determinar o tamanho do fermentador necessário, você poderá decidir sobre o estilo e o material mais adequados. Cada tipo de fermentador tem suas vantagens e desvantagens, mas sua decisão depende do orçamento e da preferência pessoal.

Tipos de fermentadores

There are three main types of fermentation tanks, let’s take a look at them.

Tanque de fermentação de topo aberto

Open-top fermenters are simple vessels without lids or seals and are the most basic type of fermenter. They are used for fermenting wine because they allow easy access and manual pressing of the cap (the layer of grape skins and seeds that rise to the surface during fermentation).

Tanque de fermentação fechado

Os fermentadores fechados têm uma tampa selada que impede a entrada de quaisquer contaminantes externos no processo de fermentação. São utilizados no fabrico de cerveja porque protegem o líquido da exposição ao ar, que pode causar deterioração ou sabores estranhos.

Variable capacity cuba de fermentação

Os fermentadores de capacidade variável têm tampas flutuantes e volumes ajustáveis, tornando-os adequados para fermentar diferentes quantidades de líquido. São populares entre os cervejeiros caseiros e os pequenos cervejeiros porque oferecem flexibilidade e ajudam a reduzir a quantidade de contacto do ar com o líquido em fermentação.

What size primary fermenter is required?

In the early stages of fermentation, a thick layer of foam will form on top of the wort, called clausen. Clausen helps protect the fermenting wort from infection and is a good indicator of how things are going. As fermentation ends, the amount of Clausen decreases.

If you were to fill a fermentation vessel with wort, Clausen would have nowhere to go and would be forced through an airlock that might be clogged. The pressure in the fermenter then increases until the airlock is blown out.

To stop this from happening, you should choose a fermenter that is 20% larger than the volume of beer you want to brew. This leaves a space at the top of the fermenter, called headspace.

Most homebrew recipes are designed to produce five-gallon batches of beer and must a six-gallon or six-and-a-half-gallon fermenter.

What size fermenter is needed for secondary fermentation?

Once fermentation is complete, you can bottle or barrel the beer, or transfer it to a second container for aging. speaking, secondary fermenter is a misnomer because almost no fermentation occurs. More hops, spices and other ingredients can also be added at this stage.

Unlike primary fermenters, primary fermenters must more headspace for Clausen formation. The secondary fermenter should be as full as possible. This minimizes the amount of air exposure and reduces the chance of oxidation and unwanted off-flavors in the beer.

What size more fermenter is needed?

The beer can be bottled or kegged, or it can be transferred to a second container for aging after fermentation is complete. The second fermenter must be as complete as possible. This reduces the amount of air exposed and the chance of the beer oxidizing and developing undesirable off-flavors. For the 5-gallon kit, you will need a 5-gallon secondary fermenter.

Fermentation tank material selection

Plastic buckets and basins

Many homebrewers use food-grade plastic buckets as their fermentation tanks. Plastic kegs are cheap, lightweight, easy to store, and can be purchased with air locks and spigots for bottling finished beer. transfer wort from pot to fermenter. Fermentation barrels are available in a variety of sizes, from 5 liters (1 gallon) to 30 liters (8 gallons). Or you can buy a food grade container and add an airlock and tap it yourself.

The disadvantage is that the lid is not sealed and oxygen can enter.

Glass bottle

Glass bottles have long been the go-to choice for home brewing and winemaking. Glass jugs and vials come in a wider range of sizes, from half-gallon (three-liter) jars to 15-gallon (54-liter) vials. The glass is wear-resistant and will not scratch. It is also 100% oxygen impermeable and does not absorb taste or odor.

Unlike buckets, small and large bottles are heavy and difficult to store because they cannot be stacked. They also usually don’t have taps, which means you have to use a siphon or rack rod to transfer your beer.

Tanque de fermentação em aço inoxidável

Stainless steel fermenters offer all the benefits of plastic fermenters but are scratch-proof, impermeable and very easy to clean. If you have the budget, Micet suppliers sell stainless steel fermentation tanks in various sizes. If you’ve ever visited a commercial brewery, you’ll notice that fermentation takes place in tall stainless steel vats that taper toward the bottom.

Conical fermenters allow breweries to remove dregs from the beer without pouring it into a second container. This means that primary and secondary fermentations can take place in the same barrel without putting the beer at risk of contamination. Conical fermenters also make it easy to harvest yeast, which can then be cleaned and reused.

How to choose the right fermenter for your needs

When selecting a fermentation tank, the following factors should be considered:

• The type of beverage or food you plan to ferment
• O seu nível de experiência e competências
• Available space in brewing or fermentation area
• O seu orçamento
• Capacidade necessária do fermentador
