     Fermenters have been perfected over hundreds of years by brewers so the fermentation cycle will do everything it is designed to do, and do it completely. Visit any brewery and compare equipment. All commercial Fermenters are essentially the same. The conical bottom is a 60o angle from the cylinder wall. The slope is just the right angle so the trub, dead yeast cells, and everything falling out of suspension will slide to the bottom at the apex of the cone. The trub can be drained with a minimum waste of good beer. The cylinder above the cone, is one unit wide by one unit tall. Freeboard above the cylinder on large systems is normally ten to twenty percent of the volume. On small systems such as ours, we have added a little extra. All commercial Fermenters have a man-way for easy cleaning access to the inside. The Mini-Brew Systems Fermenter works the same way for easy cleaning also.

 

The full size top provides a brewer the opportunity to open ferment or for lifting off ale yeast cells as they rise to the top.  The rugged food grade polyethylene walls are 5/16 inch thick. 

Commercial Fermenters have a huge gate valve at the Valve Picture bottom. The Mini-Brew System Fermenter has a one inch ball valve at the apex. Our threads are molded separately then spin welded in place, a food grade process. The thickest of yeast will flow through this large full port valve. The valve port is plated inside so brass does not come in contact with the beer. Removing the yeast cells daily will improve beer flavor and save the effort of sterilizing and risk of siphoning into a secondary fermenter. If the yeast in the bottom is not removed a day or so before racking, it can be harvested after racking. Yeast settles to the bottom in layers. Drain some of the middle layer into a sterile jar and use it to make a started for the next brew. Save the yeast in the refrigerator. The Mini-Brew System equipment is designed so gravity does the work.

A 1/2" npt racking arm thread is welded in place on the side of the cone. This valve is also used for tasting beer in process and specific gravity testing. The racking valve provides access without disturbing the settled yeast on the bottom. The finished beer, if it is removed from the bottom valve, may need to be filtered. A 1/2 inch ID tubing is used to connect the fermenter to a bright beer tank such as a corny keg or a bottling system. 

An accurate temperature reading of the working wort is an important measurement for great tastes. The natural convection's currents where the yeast is working the hardest is the most telling reading. We have spin welded a 1/2" thread on the side of the cylinder so you can install a back connected thermometer with a probe that will touch the critical area. See the Instrument page for a list of our thermometers. A 1/2-inch npt plug is shipped with the fermenter.

The legs on commercial equipment are welded to the fermenter and hold the vessel upright. Our stand has a cone inside that fits the cone of the fermenter. The two cones hold the fermenter firmly upright. Any dripping from the valves is contained within the bottom of the stand and not on the floor. The lip at the top of the fermenter and at the top of the stand can be used as handles for easy moving.

We added a 1/2 inch thread in the middle of the lid.  This thread can be used for a CIP (clean in place) nozzle or an air lock kit.  A 1/2 inch plug is included with the fermenter.

Consider this:  Starting the siphon, lifting and cleaning carboys has been eliminated. The secondary fermentation process is eliminated. Now you can fill from the bottom using gravity so aeration is controlled and outside bacterial infections are eliminated. Wort temperature control is available and measurable. Your imagination is the only limit on your hobby. Home brewers and small batch brewers can brew with equipment and attributes that professional brewers have been using for years. You'll enjoy the results.

Microbrewers and brewpubs that use our Fermenters for yeast propagation will return their investment in a few months.

Dimension: Our Fermenter designed for five gallon brewing, the f6b is 38 1/2 inches tall and 14 3/4 inches in diameter. The vessel has a total capacity of 8 gallons. The ten gallon recipe size, the f12b is 44 1/2 inches tall and is 18 3/4 inches in diameter with a total liquid capacity of 15 gallons.

The half-barrel fermenter (hbf) has a total capacity of 25 gallons. The full barrel (fbf) has a total capacity of 40 gallons. The stand is made from welded steel strapping. Delivery time for the half and full barrel Fermenters is two tp three weeks.

Our newest fermenters are the f6.8 and the f8 as shown above.
