Beer is a drink that people often drink. It is mainly made by using grain fermentation, and its taste is mellow, so it is very popular among people. Its market is also very broad. The equipment used to make beer in the beer tank will produce a large amount of organic matter such as protein, hop resin, polysaccharide, yeast and inorganic matter such as calcium oxalate and sulfate during the fermentation process. After the beer tank is emptied, organic matter and inorganic matter dirt adhere to the wall of the tank, showing a yellow brown color. In large quantities, the tartar surface appears white, like a saline-alkali surface, and inorganic and organic matter are interwoven. Therefore, for everyone to understand the beer tank mixing tank should be cleaned.
In the daily production process of each brewery, although cleaning and sterilization are strictly implemented in accordance with the established process, but because of the production pipeline inflection point, long line, tank scrubber aging, blockage, pump pressure is not compatible and many other factors, it is difficult to clean all parts of the pipeline, tank interior, especially some dead corners. However, local cleaning is not clean, which will eventually cause microbial outbreak of the whole system over time and seriously affect product quality.
Cleaning beer tank, pharmaceutical beer tank cleaning, etc. Cleaning methods:
Cleaning in the brewing and beverage industries is usually done in the hope of greater automation, saving time, efficiency and manpower. At present, the common method of beer tank washer to realize efficient cleaning of tank body, fixed ball cleaning, rotating nozzle can cleaning is widely used by enterprises. The water jet technology is used to comprehensively solve the problem. In the water jet technology, the water jet will be ejected at a higher speed after passing through the rotating nozzle, and the water jet formed by condensation after accelerating through the nozzle hole is called jet
The three-dimensional rotating can washer uses fluid to drive the impeller inside the sprinkler head, decelerates through the planetary reducer, and then drives the revolution of the base of the sprinkler head and the rotation of the nozzle, realizing the full coverage of 360° spherical high impact three-dimensional cleaning.
The fixed cleaning ball can be used to flush the tank wall, spray water from a separate jet hole with holes, and the water jet to the same position of the tank wall. Due to the size limitation of the nozzle, the force of each impact point spraying to the tank wall is very limited, and the water quantity of the point without impact is actually zero. This means that in order to achieve the required cleaning effect, a large number of high concentration of chemical cleaning agent or high temperature cleaning solution must be used for a long time.
Fixed cleaning ball can also be used as a filter screen to filter the particulate matter in the cleaning liquid, therefore, a part of the ball washing nozzle hole is easy to be blocked, resulting in unqualified cleaning of the tank wall surface, and this phenomenon is generally not immediately apparent, only to a certain extent, will be found.
A rotating three-dimensional can washer can produce repeatable and reliable results, and a variety of storage tanks, such as beer tanks, pharmaceutical tanks, fruit and wine tanks, can be cleaned using less than 20% of the water and caustic soda used in traditional spray balls.
Precautions in the cleaning process of beer tank:
(1) Wear or blockage of the can washer or rotary spray cleaning ball, which partially leads to unclean cleaning of the beer tank.
(2) In the accumulation of dirt in the end of fermentation to release the material, and comprehensive cleaning.
(3) According to the use of beer tank and other conditions, formulate the beer tank cleaning operation plan.
(4) Turn off the power, remove the lid of the tank, rinse the removed electrode with tap water, check and remove the debris in the beer tank, and pre-clean the beer tank.
(5), Prepare acid and alkaline washing liquid according to the requirements, inject water into the beer tank, add alkaline washing liquid cycle alkali washing.
(6) After cooling, remove the lye from the tank. Rinse the residual lye in the beer tank with clean water, and the PH is neutral.
(7) Add acid washing liquid to clean. Rinse the residue with clean water, PH is neutral.
(8) After cleaning, restore the beer tank and pass air into it to check whether there is leakage in the pipeline and tank.
In the process of sterilization, when the jacket passes through the steam preheating, the inlet pressure must be controlled within the working pressure range of the equipment (should not exceed 0.2MPa), otherwise it will cause damage to the beer tank. In empty and solid elimination, it is necessary to drain the remaining water in the jacket of the beer tank. Otherwise, the cylinder in the beer tank may be flattened and the equipment may be damaged. In the elimination, will also cause too much condensate resulting in dilution of the culture medium, so as to not meet the process requirements.
