conical fermenter tank

Conical fermenter tanks, also known as uni-tanks or cylindroconical vessels, are essential equipment in the beer brewing process. These specialized tanks are designed to facilitate the fermentation stage, where yeast converts the sugars from the wort (unfermented beer) into alcohol and carbon dioxide. The conical shape of these tanks provides several advantages over traditional cylindrical fermenters, making them a popular choice among commercial breweries and serious homebrewers.

The unique design of conical fermenter tanks allows for efficient yeast management and separation during fermentation. The cone-shaped bottom acts as a natural settling area for the yeast, making it easier to harvest and reuse for subsequent batches. This not only saves on the cost of purchasing new yeast but also preserves the unique flavor profile contributed by the house yeast strain.

Conical Fermenter Tank Průvodce vybavením

Conical fermenter tanks typically consist of the following components:

Komponenta Popis
Cylindrical Body The main cylindrical section of the tank, where the fermentation process takes place. It is typically made of high-quality stainless steel or other food-grade materials.
Kuželovité dno The cone-shaped bottom section, designed to facilitate yeast collection and separation. The angle of the cone can vary, but a steeper angle generally promotes better yeast collection.
Regálové rameno A movable arm or pipe located near the bottom of the cone, used for transferring the fermented beer (green beer) to the next stage, leaving the yeast behind.
Cooling Jacket An optional feature that allows for temperature control during fermentation by circulating a cooling or heating medium around the tank’s outer surface.
Ports and Fittings Various ports and fittings for attaching accessories like airlocks, sample valves, sight glasses, and clean-in-place (CIP) systems.
Izolace Insulation around the tank helps maintain consistent temperatures during fermentation.

Types of Conical Fermenter Tanks

Conical fermenter tanks are available in different sizes and configurations to suit various brewing operations. Here are some common types:

Typ nádrže Popis
Unitank A single-vessel system that combines the functions of fermentation, conditioning, and bright beer tank. It allows for the entire brewing process to occur in one tank, simplifying the workflow.
Open Fermenter An open-top conical fermenter tank, often used for top-fermenting yeasts like those used in ales. The open design allows for easier access and addition of ingredients during fermentation.
Closed Fermenter A sealed conical fermenter tank, commonly used for bottom-fermenting yeasts like those used in lagers. The closed system provides better control over the fermentation environment.
Jacketed Fermenter A conical fermenter tank with an external jacket that allows for precise temperature control during fermentation. This is essential for certain beer styles that require specific temperature regimes.

The Brewing Process with Kónické fermentační nádrže

Conical fermenter tanks play a crucial role in the beer brewing process, particularly during the fermentation and conditioning stages. Here’s a simplified overview of how they are used:

  1. Wort Transfer: After the wort (unfermented beer) has been boiled and cooled, it is transferred into the sanitized conical fermenter tank.
  2. Yeast Pitching: The appropriate yeast strain is added (pitched) into the wort, initiating the fermentation process.
  3. Primary Fermentation: As the yeast consumes the sugars in the wort, alcohol and carbon dioxide are produced. This primary fermentation stage can last several days to a few weeks, depending on the beer style and yeast strain.
  4. Yeast Settling: Once primary fermentation is complete, the yeast cells begin to settle towards the conical bottom of the tank, forming a compact yeast cake.
  5. Racking: Using the racking arm, the fermented beer (green beer) is carefully transferred from the tank, leaving the yeast behind. This process is known as racking.
  6. Conditioning: The racked beer may undergo additional conditioning or lagering stages in separate tanks or within the same conical fermenter, depending on the brewery’s process.
  7. Yeast Harvesting: The compact yeast cake collected at the bottom of the cone can be harvested and reused for subsequent batches, or discarded if a new yeast strain is needed.

This process highlights the efficiency of conical fermenter tanks in separating the yeast from the beer, enabling brewers to reuse their house yeast strains and maintain consistent flavor profiles across batches.

Conical Fermenter Tank Capacity, Spaces, Design, and Layout

Conical fermenter tanks are available in various capacities to accommodate different brewing scales, from small homebrewing setups to large commercial operations. The table below provides an overview of typical tank capacities and the corresponding brewing scales:
