Saving labor and time is an important thing in the brewing process at beer facilities, so more and more brewers are preferring high levels of automation. For example, adding PLC controls and pneumatic valves to the brewhouse so that brewers don’t need to go up and down stairs to operate the valves. But there are also things that basically need to be done to save labor, especially for larger capacity brewpubs.
We need to crush the malt and use the crushed malt for brewing, and for high volume breweries that need a lot of malt, transferring it by hand would be labor intensive.
For example, for a 2,000 liter brewery, if we brew beer malt with a 1:3 water ratio, we would need about 500 kg of malt. The milled malt mixed with water weighs over 900 kg.
(We know from the book that the weight of crushed malt mixed with water is magnified by 1.8 times). Some brewers calculate it as 2 times. This is unbearable for the average person. Therefore, we thought to add a flexible auger (conveyor belt) to transport the malt and make it a place of labor.
Usually, the flexible auger will be used in conjunction with a hopper and a hydraulic press.
The hopper is used to store the malt and according to our calculations a hopper capacity of 1500L is sufficient (for two batches). This allows us to transport the malt once with a conveyor after the crushing is finished.
According to our standard configuration, there are two types of hoppers: 45° cone hopper and 90° cone hopper. It requires a certain height. (45° cone hopper is higher). In addition, we believe that the 45° cone hopper has a better flow than the 90° cone hopper.
As for the waterer, it has internal nozzles that are connected to the faucet, so it can spray water for the malt to do premixing.
In addition, there are two types of water fillers.
One is stainless steel and the other is glass. The glass one allows you to see directly inside.
This is the basic requirement for a large capacity brewery. We can also add other designs to the project, such as level sensors, weight sensors, etc., which also help save labor.
