Draft beer equipment is very common in life, and because of these beer equipment, people can make so much beer. The cleaning of beer equipment is also related to the quality of the brewed beer, so the cleaning of beer equipment can not be ignored, let’s share with you the cleaning method of beer equipment:
I. Selection of stainless steel beer equipment
The biggest advantage of stainless steel is its insensitivity to acids and bases. However, the inner wall of the container should be as smooth as possible to ensure thorough cleaning and to remove all residual dirt. Special emphasis should be placed on the selection of equipment: the smoothing of the weld; the polishing of the inner wall.
The premise of stainless steel corrosion resistance is that the surface metal is pure and can form an inert layer. Therefore, shielding gas welding must be used to avoid oxidation and physical or chemical passivation (pickling) is required. Stainless steel is not allowed to come into contact with other iron tools because iron ions can cause corrosion
II. Fermentor cleaning
When the wine in the fermenter is empty, do not let the carbon dioxide out. You can rinse it twice with water, so that there is no smell of wine in the jar. The carbon dioxide is discharged before the alkali water is injected.
The fermenter is soaked in alkaline water. The alkaline water must be covered by the bubble cover regardless of the heat and cold. When the next time you make wine, use a pump to circulate the alkaline water for cleaning, then wash it 3-4 times with water for 60-80 seconds each time.
The sampling port must be opened when cleaning. When the cleaning is completed, the sampling port is closed. When the water pipe is removed, it is necessary to develop a good habit of disinfecting the sampling port and the link nozzle.
When the alkaline water is pumped into the fermenter, the sampling port and the air outlet must be opened! ! ! Because there is carbon dioxide in the fermenter, if it is not opened, the alkali and carbon dioxide are neutralized, and the can is easily vacuumed! ! !
III. Cleaning of hoses for beer brewing equipment
Most hoses are rubber hoses, which are dangerous connecting pipes. People are used to guessing the internal state of the hose from the outside, which is usually a big mistake.
The internal requirements of the hose are very high and it is difficult to clean. Cracks and small damage inside it are difficult to find and determine. The hose can only be cleaned with a weak base: oxidizing acids such as nitric acid and copper ions can accelerate the aging of the hose, so note that the hose and copper tubing cannot be cleaned together.
The quality of rubber varies widely. Some rubber tubes bring a certain amount of flavor to the beer, especially if it is damaged or aged inside. Therefore, people should check the food suitability of the pipe.
In metal pipes, the sealing material is used for all screw tightening. These sealing materials are as cumbersome as hoses. Because they are exposed to beer, these materials must be of legal purity and cannot be brought into any material that affects the taste of the beer.
