[0022] Since the 1980s, the cleaning of equipment has been replaced by machinery. This is especially true for dairy, beverage and other pipeline continuous operation factories. In many dairy factories, automatic in-place cleaning is used, that is, the water and washing liquid used for flushing are circulated in a closed loop in the equipment pipeline and production line, without disassembling the equipment. This technology is called cleaning in place (CIP), also known as cleaning positioning or positioning cleaning (cleaning in place).

[0023] CIP is widely used in food and beverage production enterprises. CIP is also widely used in existing pharmaceutical production. CIP is used in pharmaceutical production, and its hygiene level requirements are relatively strict. The production equipment needs to be cleaned and purified by flushing with clean water and detergent. After cleaning once, it is directly discharged to the ground and cannot be circulated for cleaning, resulting in waste of water and detergent, and the cleaning effect cannot be effectively detected.

The discharge end of the storage tank 100 is connected to a plurality of pipelines through a pipeline shunt provided with a flow control component 110 and is correspondingly connected to each of the reactors 200. The discharge end of each of the reactors 200 is shunted and respectively connected to the drainage unit 700 and the feed end of each of the recovery heating units 500. The discharge end of each of the recovery heating units 500 is respectively connected to the feed end of each of the reactors 200. The peristaltic feeding components 410 in the peristaltic feeding unit 400 are respectively connected to the feed end of each of the reactors 200. The drying unit 300 is connected to the feed end of each of the reactors 200. The pipeline detection unit 600 is correspondingly connected to the discharge end of each of the recovery heating units 500.

[0025] In one or more possible embodiments of the present invention, in combination with the accompanying drawings, as an example, a single-tank CIP cleaning system includes a group of storage tanks 100, wherein two groups of reactors 200 are provided, and are equipped with two groups of peristaltic feeding units 400, two groups of recovery and heating units 500, and two groups of pipeline detection units 600. It can be seen that the number of groups of the peristaltic feeding units 400, the recovery and heating units 500, and the pipeline detection units 600 corresponds to the number of groups of the reactors 200; the present invention will be illustrated below in combination with the above content.

[0026] In one or more possible embodiments of the present invention, Figure 2In order to pre-clean the two reactors 200, the discharge end of the storage tank 100 is connected to the first liquid infusion pipeline 130 through the first water supply pipeline 120 provided with a flow control component 110 and is correspondingly connected to each of the reactors 200. In order to facilitate the connection between the storage tank 100 and the two reactors 200, the flow control component 110 on the first water supply pipeline 120 includes a diaphragm control valve 111, a flow control switch 112, a variable frequency self-priming pump 113, and a pressure gauge 114 arranged in sequence, which can be used to control the flow of cleaning water on the first water supply pipeline 120. Correspondingly, in order to control the first liquid infusion pipeline 130, at least two groups of diaphragm control valves 111 are installed on the two first liquid infusion pipelines 130. In order to facilitate the connection with With the cooperation of other unit components, each of the reactors 200 is provided with a first liquid inlet pipe 210. As can be seen from the above, the first liquid infusion pipe 130 is connected with the first liquid inlet pipe 210 through the first water supply pipe 120. In order to clean the inner wall of each reactor 200, each of the first liquid inlet pipes 210 extends into the corresponding reactor 200 and is connected with a cleaning ball 800. When the present invention performs a pre-cleaning operation, the flow control component 110 on the first water supply pipe 120 is opened to supply water to the first liquid infusion pipe 130, and the first liquid infusion pipe 130 can be controlled to infuse liquid to the reactor 200 respectively, and the cleaning ball 800 is used to clean the inner wall of each reactor 200, so that different reactors 200 can be cleaned at different times.

[0027] After cleaning the reactor 200, the cleaning water can be directly sent from the reactor 200 to the drainage unit 700. Specifically, the discharge end of the reactor 200 is connected to the drainage pipe in the drainage unit 700 through the first drainage pipe 220. Correspondingly, in order to achieve effective and timely control, a diaphragm control valve 111 is correspondingly arranged on each drainage pipe.

[0028] The cleaning of the reactor 200 may not be clean enough once, and the reactor 200 needs to be cleaned multiple times. In order to effectively save resources and realize the repeated recycling of cleaning water and cleaning liquid, Figure 3Each of the reactors 200 is connected to a first circulation pipeline 510 provided at a feed end of each recovery and heating unit 500 through a first liquid discharge pipeline 220. The recovery and heating unit 500 includes a first circulation pipeline 510, an electric heating heat exchanger 520, and a second circulation pipeline 530. The first circulation pipeline 510 is provided at the feed end of the electric heating heat exchanger 520. The output end of the electric heating heat exchanger 520 is connected to the second circulation pipeline 530. The second circulation pipeline 530 is connected to the first liquid inlet pipeline 210. In order to facilitate flow control, a corresponding diaphragm control valve 111, a temperature sensor, etc. may be provided on the second circulation pipeline 530. A flow switch, a diaphragm control valve 111, a variable frequency self-priming pump, etc. may be provided on the first circulation pipeline 510. 113, pressure gauge 114 and other components; in this way, water is discharged through the first liquid discharge pipe 220 of the reactor 200, and after the water is discharged, it enters the electric heating heat exchanger 520 through the first circulation pipe 510 to heat the circulating water, and is connected with the corresponding first liquid inlet pipe 210 through the second circulation pipe 530, and enters the reactor 200 to achieve recycling, and the circulating water and circulating liquid can be heated. While the inner wall of the reactor 200 is effectively cleaned, the sanitation in the pipe is more effectively maintained; in order to facilitate the connection and coordination between the second circulation pipe 530 and the first liquid inlet pipe 210 in each recovery heating unit 500, in the attached drawings of this embodiment, the number marked on the end of the second circulation pipe 530 is the same as the number marked on the connected first liquid inlet pipe 210.

[0029] In combination with the above content, after multiple cleanings to meet the requirements, the circulating water or circulating liquid can be discharged from the first drainage pipe 220 into the grounded drainage unit 700 for discharge.

[0030] After pre-cleaning the pipeline and the reactor 200, the pipeline and the reactor 200 need to be dried to keep the inner wall of the pipeline and the reactor 200 dry for subsequent operations. For this purpose, a drying unit 300 is used in combination with Figure 4The drying unit 300 includes a sterilizing filter 310 connected to an external air source. The sterilizing filter 310 is connected to a plurality of groups of sequentially connected dry-burning gas electric heaters 320 through a connecting pipe. The last dry-burning gas electric heater 320 is correspondingly connected to the two first liquid infusion pipes 130 through two first drying pipes 330. The two first drying pipes 330 are respectively equipped with a diaphragm control valve 111. In this way, after the air is taken in from the outside and filtered, it is heated in turn by each dry-burning gas electric heater 320 to reach the set temperature, such as 110°C or 90°C, and then passes through the first drying pipes 330. A liquid infusion pipeline 130 and a first liquid inlet pipeline 210 enter the reactor 200, and then can pass through the recovery heating unit 500 to dry the pipeline in the recovery heating unit 500; of course, the last dry-burning gas electric heater 320 is connected to the storage tank 100 through the diaphragm control valve 111 correspondingly installed on the first drying pipeline 330, and can dry the inside of the storage tank 100 through the first drying pipeline 330, and enter the first liquid infusion pipeline 130 through the first water supply pipeline 120. The above contents can be combined later to achieve recycling and complete the drying of multiple pipelines, storage tanks 100 and reactor 200.

[0031] In order to perform alkali cleaning, acid cleaning, disinfection cleaning and other operations on the pipeline and the reactor 200, Figure 5 The present invention provides a peristaltic feeding unit 400, which supplies cleaning liquid to the pipeline and the reactor 200 through each peristaltic feeding component 410 in the peristaltic feeding unit 400. In the present embodiment, specifically, the peristaltic feeding unit 400 includes three groups of peristaltic feeding components 410, each of which includes a feeding tank 411, and the discharge end of each feeding tank 411 is correspondingly connected to the first liquid inlet pipeline 210 on the reactor 200 by setting a peristaltic pump 412. As shown in the figure, the peristaltic feeding unit 400 in the present embodiment includes three groups of peristaltic feeding components 410, and the discharge ends thereof are respectively marked a, b, and c. Correspondingly, a receiving pipe that is connected with the three groups of peristaltic feeding components 410 and has a, b, and c marks is provided on the first liquid inlet pipe. Correspondingly, a diaphragm control valve 111 is provided on each receiving pipe for controlling the input cleaning liquid.

The first water return pipeline 150 is connected with the water inlet pipe of the storage tank 100. The water inlet pipe extends into the interior of the storage tank 100 and is connected with a cleaning ball 800. Two groups of diaphragm control valves 111 are arranged on the first water return pipeline 150. By cooperating with the first water supply pipeline 120 and supplying water through the storage tank 100 with a variable frequency self-priming pump 113, the storage tank 100 is repeatedly cleaned, and the first liquid infusion pipeline 130, the first liquid inlet pipeline 210 and the peristaltic feeding unit 400 are used to supply cleaning liquid in the storage tank 100 to clean the storage tank 100 and the pipeline; in order to facilitate the discharge of cleaning water and cleaning liquid, the first water supply pipeline 120 is connected with the drainage unit 700 through a plurality of connecting pipes to discharge the cleaning sewage and cleaning liquid.
