Description

[0001] The invention relates to the technical field of beer and beverage filling production, and in particular to a clean water spraying system and a control method for tunnel spraying equipment. Background Art

[0002] In the production of beer and beverage filling, tunnel spraying equipment is needed to pasteurize beer, warm low-temperature beverages, and cool high-temperature beverages. Water spraying is usually used to raise and lower the temperature of these products. In order to reduce water and energy consumption, these devices use water pumps to extract warm water to spray the sealed beer or beverage bottles, and then collect the spray water for recycling. It is precisely because of the recycling of spray water that there is a hidden danger of water quality degradation.

[0003] In the prior art, in order to ensure the hygiene of the sprayed products, a new water flushing device is added at the end of the tunnel spraying to flush the surface of the sprayed products. Figure 1 As shown, the bottles output from the tunnel sterilizer are sent to the conveyor chain 2. There is a spray pipe above the conveyor chain, and the spray pipe has a nozzle. The nozzle sprays new water to wash the surface of the bottles on the conveyor chain 2.

[0004] However, in actual production lines, discontinuous production often occurs. There will be multiple time periods when no bottles are sent from the tunnel sterilizer 1 to the conveyor chain 2, resulting in a bottle-free period on the conveyor chain 2. The existing spray pipe 3 will continue to spray new water during the bottle-free period, resulting in a waste of water resources. Summary of the invention

The pneumatic valve 32 is connected to the clean water spraying device 4, and the controller 7 controls whether the clean water spraying device 4 sprays water through the pneumatic valve 32.

[0041] See also Figure 3 As shown, in this embodiment, the above-mentioned clean water spraying device 4 is arranged on the conveying chain 2. Figure 4 As shown, the clean water spraying device 4 includes a connecting pipeline 41, a plurality of nozzles 42 and a water pressure regulating valve 43. The water pressure regulating valve 43 and the pneumatic valve 32 are both arranged at the inlet section of the connecting pipeline 41.
