Double Walled: A stainless steel, double-walled skin is filled with a thick layer of polyurethane foam for insulation. This keeps the wort at a constant and stable temperature with minimal influence from external environmental changes, providing insulation for your fermentation that a standard jacket cannot achieve.
Integrated Gentle Heating: In the cavity of the fermenter between the outer body and cone, sits a 30 Watt, 12V heating element. Unlike standard heating elements/sources that directly heat the liquid, this heat source is designed to heat the environment in between the walls of the fermenter, which in turn heats the liquid. The fermenter acts as an artificial environment which can be heated, meaning the temperature is raised in an even and controlled manner which is much better for yeast.
Integrated Cooling Sleeve: In between the two stainless steel walls sits a cooling sleeve (also made of stainless steel). This cooling sleeve is welded onto the inner wall of the fermenter and can be hooked up to the additionally purchased Glycol Chiller. After setting the desired temperature on your fermenter, the cooling liquid travels through this sleeve, cooling the stainless steel, which then evenly cools the beer within the fermenter. The cooling sleeve never comes into contact with the beer as it is completely concealed and built into the fermenter. This also means it never needs cleaning or sanitising - a true innovation for a fermenter of this scale.
Easy Access to the Interior for Hassle-Free Cleaning: The Grainfather Conical Fermenter has a smooth interior with no additions such as cooling coils or additional sampling valves. This makes cleaning easy and minimises the risk of infection.
Golden Angle Conical: The conical shape of the fermenter is typical for professional breweries. Our conical has been designed with the 'Golden Angle' of 60º. This is the optimum angle for yeast and sediment to drop down to the bottom of the cone without getting stuck to the sides. This allows you to transfer from above the sediment line, resulting in clearer beer. The conical shape also makes it easier to mix during fermentation due to the path of convention currents that it enables to occur.
Dual Valve Tap: This all in one valve, makes the yeast dumping, transferring and sampling process easy. Sampling and transferring is done through an inlet above the sediment line, allowing for clear, sediment-free beer. Easily collect your yeast from below the sediment line with the same unique valve for recultivating and pitching. The innovative design of the valve allows for this dual functionality and means less cleaning for you.
Temperature Control: The temperature controller easily snaps on via magnets and pogo pins. It allows you to accurately set the temperature and you can even control a temperature schedule/profile. You can set up to four profiles each with five stages. Control the fermenters integrated heating element and the cooling when paired with the Glycol Chiller.
