Description

Technical Field

[0001] The utility model belongs to the technical fields of instant killing systems, filling machines and pipeline cleaning, and particularly relates to a device and a system for improving the cleaning efficiency of instant killing systems, filling machines and pipelines. Background Art

[0002] The filling K-line equipment of a beer company is equipped with a beer instant killing system with a maximum flow rate of 3 m 3 / h. The front end of the instant killing system is connected to a DN50 pipeline about 40 meters long, and the rear end is connected to a clear wine buffer tank and a filling machine. When the equipment is cleaned, due to the flow rate limitation of the instant killing system, it takes 30 minutes for the cleaning liquid to flow from the CIP through the instant killing system to the buffer tank, then to the filling machine and finally back to the CIP tank. The cleaning flow rate of 3 m 3 / h is insufficient for scouring the DN50 pipeline, the 1.2 m 3 buffer tank and the filling machine. The equipment cleaning depends on the soaking and heat exchange of the cleaning liquid, and the cleaning effect is not good. After cleaning verification, it takes 210 minutes to complete the cleaning of the filling K-line equipment. Compared with the cleaning time of about 90 minutes for other production lines, its cleaning efficiency is 230% lower, mainly due to the flow rate limitation of the instant killing system.

[0003] The instant killing system itself belongs to an individual unit of the equipment, mainly composed of a three-stage thin plate heat exchanger, a pressurized beer pump, a heating system, a heat preservation system, a cooling system, a pipeline system and a control part. Since the pipe diameters of the inlet and outlet connecting pipelines are DN25, when cleaning at a flow velocity of 1.5 m / s, only a flow rate of 2.65 m 3 / h is required. Therefore, when the instant killing system is cleaned as an individual unit, a flow rate of 3 m 3 / h can meet its own cleaning requirements, while a flow rate of 10.6 m 3 / h is required for the DN50 pipeline to meet the cleaning requirements.

[0004] In the past, to solve the problem of mismatched cleaning flow rates, a separate CIP system had to be equipped for the instant killing system, and the filling machine and the wine supply pipeline needed to achieve CIP switching cleaning through tube sheets. This not only incurred huge investment costs but also required solving the problem of on-site installation space for CIP equipment.

[0005] Currently, there is a lack of a device for improving the cleaning efficiency of "instant killing systems, filling machines and pipelines", which can reduce the system transformation cost while effectively improving the cleaning efficiency and avoiding the problem of large-scale transformation required to improve the cleaning efficiency of "instant killing systems, filling machines and pipelines" in the past.

[0057] S4. Cool and flush with water for 10 minutes: First, turn on the "first automatic reversing valve 2 and the second automatic reversing valve 3" simultaneously (refer to Figure 3 and Figure 5 ), make the pipeline of "wine supply pipeline - pipeline connector 1 - buffer tank 43 - filling machine 44" conduct, cool and wash the "wine supply pipeline, buffer tank 43 and filling machine 44" for 5 minutes, and then turn off the "first automatic reversing valve 2 and the second automatic reversing valve 3" simultaneously (refer to Figure 2 and Figure 4 ), make the pipeline of "wine supply pipeline - instant kill system 42 - buffer tank 43 - filling machine 44" conduct, and cool and wash the instant kill system for 5 minutes.
