Description

Technical Field

[0001] The utility model relates to the technical field of beverage filling equipment cleaning, in particular to a cleaning system for large-particle fruit pulp filling equipment. Background Art

[0002] With the development of society, the beverage filling industry in China is becoming more and more developed, and the filling equipment and filling technology of fruit pulp beverages are constantly innovating. By adding fruit grains to fruit pulp beverages, not only can the visual appearance of fruit pulp beverages be enhanced, but also the taste and flavor of fruit pulp beverages can be enriched, and the nutritional value of fruit pulp beverages can be improved. Therefore, it is easier to gain the recognition of consumers.

[0003] CIP cleaning means CLEAN IN PLACE (in-situ cleaning). CIP cleaning is a cleaning system that can clean the production equipment without disassembling it and can be operated safely and automatically in a simple way. It has been introduced into almost all food, beverage and pharmaceutical factories. CIP cleaning can not only clean the machine, but also control microorganisms.

[0004] In the current fruit pulp beverage filling process, usually the fruit pulp and fruit grains are first stirred and mixed, and then the mixed fruit pulp beverage is filled into beverage bottles through a filling machine. However, the fruit grains and fruit pulp are likely to precipitate in the filling machine, resulting in different fruit grain contents in each bottle of beverage during beverage filling. The large-particle fruit grains are also likely to block the filling nozzles of the filling machine, causing the filling machine to malfunction. Since it is difficult to clean the inside of the filling machine, equipment pollution is likely to occur when the sediment and blockage are not completely discharged for a long time. To achieve CIP cleaning of the inside of the large-particle fruit pulp filling equipment, the cleaning system needs to be improved. Summary of the Utility Model

One end of the second valve assembly 53 is communicated with the fruit pulp tank 1, and the other end is communicated with the upper ring cavity 522. When starting the first cleaning circuit, the cleaning liquid in the liquid inlet pipe 51 enters the upper ring cavity 522 from the first valve 521, then enters the corresponding plunger cylinder 2 through the water inlet 26, and then enters the inside of the tank body 11 through the three-way valve 4 and is discharged through the drain pipe 57.

[0044] Continue to refer to Figure 4 , the third valve assembly 54 includes a third valve 541, a lower ring cavity 542, and a conducting member 543.
