Description

Technical Field

[0001] This utility model belongs to the field of sterilization technology, specifically a CIP weak acid water sterilization system. Background Technology

[0002] Clean in place (CIP), also known as cleaning in place or in-place cleaning, is widely used in highly mechanized food production such as dairy products, juices, pulps, jams, and wines. The CIP cleaning sequence is: water wash - alkaline wash - water wash - acid wash - hot water wash, where the purpose of hot water washing is sterilization. For sterilization of sugar-based tanks, a certain concentration of weak acid water is generally used. Existing technology uses piping for weak acid water sterilization as follows: Figure 1 As shown, during the sterilization of the glycosidic tank, the sterilization process is typically paused until the temperature inside the tank drops below 50°C. The tank is then locked, the manhole is opened, and operators go to the second-floor platform to add lactic acid through the manhole. The reflux pump is then activated, drawing the lactic acid into a hot water tank and into the water circulation system. A sample is taken from the hot water tank to test the lactic acid concentration to ensure it meets the standards. This sterilization process requires operators to go to the second-floor platform to add lactic acid, which is labor-intensive and poses a risk of burns. Furthermore, the amount of lactic acid added manually is uncontrollable, potentially leading to overdosing or requiring multiple additions to meet the requirements. Utility Model Content

[0003] The purpose of this invention is to provide a CIP weak acid water sterilization system to save manpower, eliminate the safety hazards of burns, and avoid the problem of uncontrollable addition of weak acid by manual addition.

[0004] To achieve the above objectives, the technical method adopted by this utility model is as follows:

[0005] A CIP weak acid water sterilization system includes a heating and circulation mechanism, a water outlet mechanism, and a weak acid addition mechanism. The heating and circulation mechanism includes a hot water tank, a circulation pump, a heat exchanger, and circulation pipelines. The hot water tank and the circulation pump, the circulation pump and the heat exchanger, and the heat exchanger and the hot water tank are all connected through circulation pipelines. The output end of the hot water tank is connected to the tank to be sterilized through the water outlet mechanism. The weak acid addition mechanism is connected to the circulation pipelines.

[0006] As a limitation: the weak acid adding mechanism includes a weak acid tank, a diaphragm pump and a one-way valve. The output end of the weak acid tank is connected to the input end of the diaphragm pump, the output end of the diaphragm pump is connected to the input end of the one-way valve, and the output end of the one-way valve is connected to the circulation pipeline.

[0007] As a further limitation: the output end of the one-way valve is connected to the circulation pipeline between the hot water tank and the circulation pump.

[0008] As a further limitation: the output of the one-way valve is connected to the circulation pipeline between the circulation pump and the heat exchanger.

[0009] As a further limitation: the output end of the one-way valve is connected to the circulation pipeline between the heat exchanger and the hot water tank.

[0010] The beneficial effects achieved by this utility model, due to the adoption of the above-mentioned solution, compared with the prior art, are as follows:

[0011] This utility model provides a CIP weak acid water sterilization system, which connects a weak acid addition mechanism to the circulation pipeline of the heating circulation mechanism. The weak acid is circulated to the hot water tank through the circulation pipeline, saving manpower and eliminating the safety hazard of burns. The weak acid is transferred to the circulation pipeline through a diaphragm pump and a one-way valve. The flow rate of the weak acid is controlled by adjusting the compressed air of the diaphragm pump, and the one-way valve prevents hot water from flowing back into the weak acid addition mechanism, avoiding the problem of uncontrollable addition of weak acid by manual addition.

[0012] This invention is applicable to CIP weak acid water sterilization. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments. However, those skilled in the art should understand that the present invention is not limited to the following embodiments. Any improvements and equivalent changes made based on the specific embodiments of the present invention are within the scope of protection of the claims of the present invention.

[0020] Example 1

[0021] A CIP weak acid water sterilization system, such as Figure 2As shown, the system includes a heating and circulation mechanism, a water outlet mechanism, and a weak acid addition mechanism. The heating and circulation mechanism includes a hot water tank 1, a circulation pump 2, a heat exchanger 3, and a circulation pipeline 4. The hot water tank 1 is connected to the circulation pump 2, the circulation pump 2 to the heat exchanger 3, and the heat exchanger 3 to the hot water tank 1 via the circulation pipeline 4. The output end of the hot water tank 1 is connected to the sterilization tank 6 via the water outlet mechanism. The weak acid addition mechanism includes a weak acid tank 8, a diaphragm pump 9, and a one-way valve 10. The output end of the weak acid tank 8 is connected to the input end of the diaphragm pump 9, the output end of the diaphragm pump 9 is connected to the input end of the one-way valve 10, and the output end of the one-way valve 10 is connected to the circulation pipeline 4 between the circulation pump 2 and the heat exchanger 3.

[0022] In this embodiment, the sterilization tank 6 is a sugar-based tank; the weak acid in the weak acid tank 8 is lactic acid; the water outlet mechanism includes a water outlet pipe 7, which is connected to the sterilization tank 6 via a reflux pump 5.

[0023] When the CIP weak acid water sterilization system of this embodiment is working, the amount and time of lactic acid addition are confirmed, the one-way valve 10 and the compressed air control knob of the diaphragm pump 9 are opened, and the flow rate of lactic acid is controlled by adjusting the compressed air of the diaphragm pump 9, thereby controlling the amount of lactic acid added. The lactic acid in the weak acid tank 8 is pumped into the circulation pipeline 4 and enters the hot water tank 1 through the circulation pipeline 4. The sample is taken through the sampling valve on the hot water tank 1 to detect whether the lactic acid concentration meets the standard. If the lactic acid concentration meets the standard, the weak acid water is pumped into the sterilization tank 6 through the outlet pipeline 7 and the return pump 5 for weak acid water circulation sterilization.

[0024] Example 2

[0025] like Figure 3 As shown, the structure of this embodiment is basically the same as that of embodiment 1. The difference is that the output end of the one-way valve 10 is connected to the circulation pipeline 4 between the hot water tank 1 and the circulation pump 2, so that the lactic acid enters the hot water tank 1 through the circulation pump 2 and the heat exchanger 3 in sequence. The structure is completely the same as that of embodiment 1, and will not be described in detail in this embodiment.

[0026] Example 3

[0027] like Figure 4 As shown, the structure of this embodiment is basically the same as that of embodiment 1. The difference is that the output end of the one-way valve 10 is connected to the circulation pipeline 4 between the heat exchanger 3 and the hot water tank 1, so that lactic acid can directly enter the hot water tank 1 through the circulation pipeline 4. The structure is completely the same as that of embodiment 1, and will not be described in detail in this embodiment.
