Description

Technical Field

[0001] The utility model belongs to the technical field of can cleaning, and mainly relates to a beer can washing system. Background Art

[0002] In the beer and beverage industry, cans have good packaging material advantages. Usually, the inside of the cans will be cleaned before filling. Cleaning can ensure that there is no dust, oil, metal chips or other impurities in the cans, so as to prevent these pollutants from affecting the quality and safety of the beverages. Cleaning prevents cross contamination. If there are ingredients from previous products left in the cans, they may react chemically with the beer to be filled, resulting in quality degradation or food safety issues. After the beer is filled, in order to reduce the oxygen increase problem caused by filling, the following methods are usually used: 1. Gas protection, conveying inert gas such as carbon dioxide to the can mouth after filling to reduce oxygen contact; 2. Fast filling, speeding up the speed to reduce the contact time between beer and air; 3. Foaming method, through knocking, rapid pressure relief, and spraying a small amount of high-temperature and high-pressure liquid to generate foam to protect the lower layer of wine in an oxygen-isolated state. The above methods of reducing oxygen increase will basically produce residual foam on the can cover after sealing. This part of the foam will remain at the can mouth. If it is not rinsed in time, the residual foam will enter the bottle warmer, causing the water quality in the bottle warmer to deteriorate. The residual water in the can body contains nutrients, which will cause bacteria and mold on the surface of the can, bringing certain product quality risks. That is, after the beer is filled and capped, the can mouth needs to be cleaned.

[0003] The existing internal cleaning device of cans is a cleaning device for metal can production disclosed in a Chinese patent document with authorization announcement number CN218223945U, which includes a cleaning box and a flushing assembly. A transmission assembly for brushing metal cans is arranged between the two sides of the interior of the cleaning box. The flushing assembly for flushing the metal can is arranged in the middle of the front end of the cleaning box, and the flushing assembly includes a carrier, an electric push rod, a four-way pipe, a water inlet pipeline, a water pump, a round pipe, a support pipe and a flushing nozzle. An electric push rod is installed in the middle of the rear end of the carrier, and a four-way pipe is arranged at the output end of the electric push rod. The rear end of the four-way pipe located in the middle position is connected to the water inlet pipeline, and the other end of the water inlet pipeline is provided with a water pump, the round pipe is arranged at the pipe mouth of the four-way pipe, and the outer side of the round pipe is provided with a support pipe. The cleaning device for metal can production supports and limits the metal can body through the round pipe and the support pipe, so that the metal can body is placed inverted to be cleaned, which can speed up the drainage of water stains and save cleaning procedures and use costs.

[0004] The existing cleaning device for the opening of an aluminum can, after sealing, is a transmission-type high-efficiency aluminum can cleaning device disclosed in the Chinese patent application document with the application publication number CN108526167A. It includes a cleaning tank, a spray head at the top of the cleaning tank, an annular circulating conveyor chain, a friction plate at the bottom of the cleaning tank, and conveyor rollers arranged at equal intervals on the annular circulating conveyor chain. During actual use, an operator places the aluminum can to be cleaned between two adjacent conveyor rollers of the conveyor chain, then starts the conveyor chain to drive, and then sends the aluminum can into the cleaning tank. The spray head at the upper part of the cleaning tank sprays and washes the surface of the aluminum can body, and the friction plate at the bottom drives the aluminum can to roll, making the cleaning more comprehensive.
