Summary of Contents for BREWHA Equipment Co Ltd. BIAC

  • Page 2 BREWHA BIAC User Manual Dear Customer, We are delighted that you have chosen a BREWHA BIAC for your brewing system! We trust that it will bring you many fun-filled hours of brewing, and of course, many times spent enjoying the fruit of your craft with your friends, family and/or customers.
  • Page 3 WARNING!! While BREWHA designs its systems with safety as a primary concern, always keep the following in mind: These vessels are not designed to withstand more than 3psi pressure in the 3-in-1 fermenter (14.9psi in the 4-in-1 fermenter) and 5psi in the 3-in-1 fermenter jacket (7psi in the 4-in-1 jackets).

  • Page 5: Installing A Ground Fault Interrupter

    BIAC User Manual Installing a Ground Fault Interrupters BREWHA recommends that brewers consider having a GFCI/GFI (Ground Fault Circuit Interrupter) installed on their power supply. While most electrical panels will have fuses or breakers, they do not often have a GFI. Breaker boxes (the electrical panel often found in laundry rooms) will prevent too much overdraw, but a GFI will respond much faster than a breaker or fuse to any deviation in electrical current.

  • Page 6: Electric Heating Elements

    The most common period of failure is while recirculating during mashing and/or vorlauf. In the BIAC, wort from the Mash Colander drains into the fermenter, and the pump pulls this wort out the bottom of the fermenter and returns it above the grain in the Mash Colander.
  • Page 7 BIAC User Manual your supplier do it for you). A general width guideline is 0.04–0.048”/1–1.2mm. If you still have a problem, go slightly wider. If you are experimenting with gelatinous or gummy cereals (e.g., oats or rye), you can include rice hulls to help counteract the ‘gummy’ effect and keep the bed fluid.
  • Page 8 Safety Note 2: When brewing low-volume batches, it is also important to be careful that the element is not exposed during the boil. To ensure that the water level will not drop to the point where the element is exposed, during filling you need to first observe/calculate the volume at which the element is fully covered (approximately 20% of the total volume of the fermenter).

  • Page 10: Preventing Damage To Vessel Jackets

    Safety Preventing damage to vessel jackets Every hose and tank is designed with a maximum allowable working pressure (MAWP), which if exceeded, will cause damage and pose a safety hazard. The BREWHA tank jackets have been designed to hold up to 5psi of pressure (7psi in the Microbrewery 4-in-1 fermenters), which is more than enough to allow adequate flow rates for chilling wort and maintaining temperature during fermentation.

  • Page 11: Securing Sanitary Clamps Against Accidental Loosening

    BIAC User Manual Securing sanitary clamps against accidental loosening Caution needs to be taken when loosening the sanitary clamps to ensure that the correct clamp is being loosened. Otherwise, instead of removing a hose fitting, one might remove the entire valve and suddenly have contents spilling out of the fermenter.

  • Page 13: Cleaning And Sanitizing Stainless Brewing Equipment And Preventing Rust

    Cleaning and sanitizing stainless brewing equipment and preventing rust One of the very useful features of the BREWHA BIAC is that the fermenter is boiled in which makes perfect sanitation much easier to achieve—the heat of the boil will sanitize the fermenter so chemically sanitizing the vessel is not necessary.
  • Page 14 Installation formed on the surface at the point of that damage. The good news is, with a little cleaning and care the chromium oxide layer is self -healing... Stainless steel and the chromium oxide layer actually thrive on proper cleaning. For everyday cleaning of non oxidized soils, dust, dirt and fingerprints, a mild soap/detergent (dish detergent) and warm water solution should be used.

Usually this type of corrosion will manifest as pitting or pinholes because of the accelerating effect of localization.

    The BIAC being shown here is the Small version; larger models are almost identical. The Microbrewery 4-in-1s (MB) are almost identical to the Homebrewery 3-in-1s (HB) for almost all aspects of the install (special note will be made where they differ).

During fermentation, the brewer can dump yeast/trub out the bottom port when fermentation is ending (after about 4-5 days with ales) to prevent the yeast ‘cake’...

When the fermenter needs chilling, the ETC will power the Chiller pump (or Chiller itself) instead of the TCV to let cool water circulate through the jacket.

The longer pump hose (if Figure 25 purchased) can be repurposed but be sure to sanitize it first (rinse it well and place it for 5 minutes in a pot of boiling water). With the distal end of the hose in water, it forms a trap to prevent flies or bacteria from entering the fermenter.

If using a March 815 Pump Assembly (model 815 comes with systems under 100L/25gal and model 7S with systems larger than 100L/25gal), wrap the Figure 27 NPT male threads with teflon plumber’s tape and attach the tri clamp fitting (some food-grade Teflon paste can be applied to the thread prior to the tape if it is difficult to form a seal).
  • Page 24 Installation step 15). 15. A valve should be installed either to the top (outlet) port on the pump, or to the inlet port on the Mash Colander (shown in picture below), whichever is easier to access. Install the Mash Colander 90° hose barb to the inside port on the Mash Colander and attach a short hose (60–90cm/2–3’) to direct the wort back into the top of the Mash Colander.

  • Page 25: Assembling The Brewha Sanitary Ball Valve

    BIAC User Manual Assembling the BREWHA Sanitary Ball Valve Disassembling a valve to remove any sediment that is trapped inside is essential sanitary technique for a brewery. The BREWHA Sanitary Ball Valve is the simplest and easiest valve you’ll ever reassemble. Aside from the very first time (when a wrench may be needed to loosen the nut on the handle) no tools other than your fingers are required to disassemble and reassemble the valve.

    Installation Installing the BREWHA Brewing Power Controller The BREWHA Power Controllers (Tabletop and wall-mounted Programmable Touchscreen) are designed to give safe and easy control for heating water with 208–240V/high amperage power. Both the 240V/30A Tabletop Power Controllers that are optional with the 240V BIACs under 100L/25gal capacity and the larger, splash-down, wall-mounted Programmable Touchscreen Power Controllers use the same general principles for setup and operation.

Then confirm that the voltage into the Power Controller is according to the specifications (particularly with 3 phase power, sometimes one leg can be higher voltage).
  • Page 33 BIAC User Manual Programming and Operating the BREWHA Electronic Temparture Controller (ETC) Overview The ETC contains one temperature probe and two independent outputs. One output is for cooling and the other one is for heating. It can be used for applications such as heating during mashing or fermentation, or for cooling post-boil and during fermentation.

The Sensor Failure defines what the output would be if the sensor fails. It is a safety feature. It can be set to 0-0, 0-1 or 1-0. For brewing, the best option is generally 0-0 as this will shut off any heater that is connected.

Keep a bottle of diluted Star San on hand and liberally apply it to any object that may contact the wort/beer.

After boil, once the target fermenting temperature is attained, the TCV closes, and the flow of chilling fluid into the jacket is stopped. This is useful during the initial chill, so one can program the desired pitching temperature and not have to supervise it, and also during fermentation to precisely maintain temperatures inside the fermenter when using tap water for cooling.
