How to calculate the volume of fermenter and amount of yeast For example, Condition: One conical fermenter, total height 9.4m, diameter 4.2m, conical bottom height 3.6m. Question 1: How many liters of beer can be filled in this fermenter? Question 2: How many kilograms of yeast can be produced after fermentation? Question 3: How many kilograms of dry yeast can be produced after fermentation? Answer to question 1: Side wall height=9.4m-3.6m=5.8m Volume of side wall: Vz=πr2h Vz=3.14x2.1x2.1x5.8=80.31m3 Volume of conical bottom: Vk=1/3πr2h Vk=1/3x3.14x2.1x2.1x3.6=16.62m3 V=Vz+Vk=80.31+16.62=96.93m3=969.3HL Answer to question 2: It can produce 1.5-2.5kg pulpy yeast per hectolitre beer. We assumes 2kg here. Amount of yeast=969.3x2=1938.6kg Answer to question 3: For pulpy yeast (including 80% water), 40% of them is usually used for propagation and 60% is used for producing dry yeast(including 7% water). Amount of dry yeast=1938.6kgx(1-85%)...

How to protect beer from external factor affecting In addition to brewing techniques, there are also many external factors affecting beer quality and stability, such as temperature, time, light and mechanical vibration etc. 1.  Temperature The beer should be stored with low temperature. Beer aging speed will be double for each 10℃ rise in temperature. So, it is necessary to control the external temperature strictly during storing and transporting in order to 100% guarantee there is not aging flavor when consumers drinks. In laboratory, the aging degree can be reflected by measuring aniline amount. 2.  Light The beer would produce MBT if exposing light with 350-500nm. The MBT has bad sulphur smell. Its flavor threshold is lower than 0.0001mg/L and it is generated by dissimilation of α-acid in hops, which is harmful for beer flavor. So, the beer would have bad smell with sun or fluorescent   lamp  exposure. Brown bottle has best photophobism, next is g...

5000L microbrewery equipment in Finland 5000L Four vessel brewhouse structure: mash tun, lauter tun, kettle tun and whirlpool tun with double size hot liquor tank and cold water tank.  Fermentation unit: Six sets 5000L conical jacketed fermenter.

Beer Freeze in fermenter Does beer in fermenter have risk of freezing? It's actually a common misconception that alcohol liquid doesn’t freeze. Alcohol liquid does freeze, so does beer in fermenter. There are two main factors causing beer freeze. The first factor is that the coolant temperature is too low. The coolant temperature had better keep between 4℃ and -6℃, the lowest temperature can not exceed -8℃. In some breweries, the coolant temperature reaches -15℃, which might freeze beer in fermenter and affect final beer quality and stability. The second factor is that the design of cooling jacket is not very reasonable and the outside temperature is too low. The coolant inlet should not be opened on low temperature area of fermenter. Otherwise, it is also easy to cause beer freeze. At this point, you might be curious what temperature does beer freeze. In fact, the specific beer freeze point (T) is related with al...

2000L microbrewery equipment is finished and will be ship to Canada soon. Cheers!

American Brewery Equipment Cases ---7 bbl microbrewery and 1 bbl pilot system in Louisiana, US The 7 bbl microbrewery and 1 bbl pilot system of Louisiana Purchase Brewing Company are installed and run in beginning of 2017. It is really a happy experience to work together and cooperate with the owner of Louisiana Purchase Brewing Company, Mr Andy. He is very professional and experienced about craft beer brewing, also kind and passionate to exchange experience with others. Here, let’s learn more details about this project. Part 1 Configuration of 7 bbl microbrewery Mill:  300~500kg/hr Brewhouse:  combined three vessel, mash/lauter whirlpool tun and brew kettle with double size hot liquor tank. The whirlpool tun is designed under mash/lauter tun in order to save both budget and floor area. The brew kettle and hot liquor tun is heated by direct fire(burner). If budget allows, we suggest a agitator in brew kettle as the burner only heat tank bottom and the wort near to bottom is ...

How to do step infusion with PID and PLC control Step infusion is a common brewing method in many microbreweries. It means the mash temperature would increase and keep in various stage. Take a example. There are four stages for step infusion. Stage 1: 30-35℃ for 30 minutes Stage 2: 55-65℃ for 30-60 minutes Stage 3: 65-68℃ for 30-60 minutes Stage 4: 76-78℃ for 10 minutes For PID control , you need to set up target temperature before every stage and control the time by yourself. That is to say, before stage 1, you should set target temperature 30-35℃. Then wait the mash being heated to 30-35℃. After that, calculate the time to keep the mash under 30-35℃ for 30 minutes. Next, set the target temperature of stage 2, 55-65℃ and wait the mash being heated to 55-65℃. The following process will be similar with sage 1. The whole procedure must require a brewmaster staying there always. For PLC control , it makes the brewing much easier as you can input the temperature and time in advance for a...

                                HSA-Hot side aeration Nowadays, there are having a lot of talk about hot side aeration(HSA) as HSA has been an important focus among brewers. Hot side aeration can occur anytime the wort is hotter than 80°F. It includes mashing, lautering, wort boiling and whirlpool. It will allow oxygen to chemically bind to various wort compounds and it will not be affected by the subsequent boil. Over time, these compounds will break down, freeing atomic oxygen back into the beer where it can oxidize the alcohols and hop compounds producing off-flavors and aromas. In order to avoid hot side aeration during saccharification, there are many details should be considered when designing brewhouse. 1.Hydrator with elbow The malt is mixed with mashing water in hydrator. We can call the mixer as mash. The mash would run into mash tun along the side wall as we design the hydrator outlet wi...

Canada beer brewery equipment cases                      --3000L Microbrewery equipment in Calgary   Part 1: Configuration of General introduction of this 3000L beer equipment    The turnkey 3000L  beer brewery equipment  included the double batch 6000L jacketed fermenters and brite tanks.

It especially good for brewing 2 batches per day.    The 3000L micro brewery equipped with bottom grain rake and grain out door, that makes the grain rake more stable and powerful during brewing and more easily for removing the spent out from the lauter tun.   Part 2: The layout design  ...

Corn in craft beer brewing In craft beer brewing, a secondary starch source (an adjunct) may be used, such as maize (corn), rice or sugar. Here, let us learn together why and how corn is used for beer brewing. Why is corn used for beer brewing? 1.The starch source in corn is easy to cook and mash. 2.The beer brewed with corn is mouthful and has special aroma. 3.The corn does not contain anthocyanin which would case beer cloudy, which is beneficial to beer storing. How is corn used for beer brewing? When the corn is used as secondary starch source for beer brewing, there are three types for your choice. The first is corn particles. The husk would removed firstly, then the corn is grinded to particles and dry to 12%-14% water content. The second is cornflakes. The corn would be pitched between two rollers with high temperature and pressed. During pressing, the starch source is be cooked. The third is corn starch. Remove embryo and protein. Just remain corn starch which is easy to amylol...

2000L Turnkey Brewery in Holland When customer make popular beer with our equipment, and when customer’s beer business dream come true, that is what really make sense we think as a beer equipment supplier. In June, 2017, yes, another popular  2000L brewery  was born in ‘windmills country’,Netherlands. We feel honor for that. Now, let’s learn the brewery establish process together. Part one: Home brewing experience Many great breweries are usually developed from home brewing. By home brewing, great beer occur, brewing experience is accumulated. When people found one thing interesting, then where sharing and enjoying begins. Hoping nice beer could be enjoyed by more people, the idea to open a brewery appeared. Yes, this is a nice starting. Part two: relaxed discussion about brewery project. This 2000L brewery project is based on two vessel brewhouse with 2000L fermenter. Due to the area limitation, the fermenter...
