 System and method for cleaning and disinfecting related equipment of beer production process

Technical field

 Beer is rich in nutrients and has a low alcohol concentration, so it is easily contaminated by microorganisms and the quality of beer is adversely affected. Contaminating bacteria in beer production come mainly from air, water, raw materials, cold wort, yeast, equipment and piping, packaging materials, and various utensils and operators. Therefore, timely disinfection and sterilization of various tools, production equipment, production environment and packaging materials in the beer production process is an important measure to ensure the quality of beer. It is therefore important to choose the appropriate disinfectant and the proper disinfection method.

 The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

 The raw water in the present invention refers to water which is input to the disinfecting system of the present invention. The embodiment of the present invention uses tap water as raw water, but since the disinfecting system of the present invention is equipped with a filtering and softening device, the source of raw water can be widely used, and is not limited to tap water. The filtered and softened water is referred to as demineralized water, which is used for electrolysis, preparation of an electrolytic solution, or as a diluent for dilution ratio. The demineralized water is electrolyzed in the electrolysis module, and an acidic oxidation potential water is generated on the anode side and an alkaline reduction potential water is generated on the cathode side in the electrolysis.

 The cleaning and disinfecting system of the present invention includes an oxidizing potential water generator device and a cleaning and disinfecting device that can be designed and installed in the field of a liquid beverage production facility.

 The cleaning and disinfecting apparatus of the present invention may be a different apparatus for disinfecting different apparatuses, for example, it may be a CIP system, a spray device, a shower device, an automatic induction hand washing device, and/or a sterilization tank.

 Referring to FIG. 2A, the oxidation potential water generator device may mainly include a filtration and softening device, an electrolytic solution preparation and supply device, an electrolytic module, an acidic water storage device, an alkaline water storage device, an acidic water delivery device, and an alkaline water delivery device. The device, the central control device, and the potential water physicochemical index detecting device (which may be disposed in the acidic water storage device and/or the alkaline water storage device as needed, not shown). Through the coordinated cooperation of these system devices, the central control device centrally controls the oxidation potential water to be delivered to each device of the liquid beverage production process to ensure daily cleaning and disinfection treatment.

 The potential hydrophysiology index detecting device of the present invention may include one or more sensors, for example, one or a combination of a pH detecting sensor, an ORP detecting sensor, an effective chlorine concentration detecting sensor, and the like, as needed. A person skilled in the art can set a corresponding monitoring sensor according to the parameters that need to be detected.

 The system for cleaning and disinfecting the related equipment of the liquid beverage production process using the oxidation potential water of the present invention can be designed and installed on the site of the liquid beverage production equipment. The tap water is sent to the electrolysis preparation and supply device and the electrolysis module through a filtration and softening device. The electrolytic solution preparation and supply device transports the prepared electrolytic solution to the electrolytic module, and the acidic water and the alkaline water generated by the electrolytic module are respectively sent to the acidic water storage device and the alkaline water storage device, and the stored acidic water is stored. And the alkaline water is sent to the cleaning and disinfecting device through the acidic water conveying device and the alkaline water conveying device, respectively, for disinfecting each device of the liquid beverage production process. The central control device controls the cooperation between the above devices to control the opening and closing of the electrolysis module, and controls the electrolysis preparation and supply device according to the water discharge index reflected by the potential water physical and chemical index detecting device provided in the potential water storage device. The concentration of the electrolyzer and/or the amount of demineralized water entering the electrolysis module stabilizes the effluent index of the potential water within the desired range.

 The electrolyte preparation and supply device can be implemented in a variety of ways. As an embodiment, as shown in FIG. 8, the electrolytic solution is added to the electrolytic solution preparation reservoir 8 through the preparation tank electrolyzer injection port 31, and a fixed amount of the electrolytic solution is added to the electrolytic solution preparation reservoir 8 each time. . Each time the electrolytic solution is injected into the electrolytic solution preparation liquid storage tank through the electrolytic solution injection port 31 of the preparation box, the start of the electrolytic solution preparation mixed mixing pump 30 is mixed and stirred to prepare the liquid storage tank 8 for the electrolytic solution. The electrolytic agent in the medium can be sufficiently dissolved and the concentration of the electrolytic solution can be uniformly mixed.

The mixing agitation pump 30 is located outside the electrolytic solution preparation reservoir 8, and two pipelines are disposed inside the electrolytic solution preparation reservoir 8 to be connected to the mixing agitating pump 30, and the electrolytic solution is pumped through the agitating pump solution suction port 32. The agitating pump 30, the electrolytic solution is pumped out to the electrolytic solution preparation reservoir 8 through the agitating pump solution discharge port 33. The agitating pump solution discharge port 33 can be disposed at an inclination angle of about 45 degrees with the bottom of the electrolytic solution preparation reservoir 8, thereby ensuring dissolution of the electrolytic solution preparation reservoir 8 when the agitation pump 30 is in operation. The liquid can form a vortex to rotate so that the electrolyte solution is sufficiently uniformly mixed.

 When the central control unit 9 detects that the physical and chemical indicators of the acidic water have changed by the acidic water raw material physicochemical index detecting device 14 located in the acidic water storage tank 13, the central control unit 9 can be changed on the one hand by controlling the electrolytic solution supply pulse pump 10. The pulse frequency; on the other hand, when the electrolytic agent is added to the electrolytic solution preparation liquid storage tank 8, the control electrolysis preparation electromagnetic valve 6 is injected into the electrolytic solution preparation liquid storage tank 8 to inject soft water, and the liquid level is prepared by the electrolytic solution. The signal data of the sensor 7 calculates the concentration of the electrolytic solution in the electrolytic solution preparation reservoir 8. Thus, by controlling the length of time during which the electrolysis agent is opened to prepare the solenoid valve 6, the concentration of the electrolytic solution in the electrolytic solution preparation reservoir 8 can be adjusted.

 The pulse frequency of the electrolysis agent supply pulse pump 10 is directly related to the concentration of the electrolyte solution in the electrolytic solution preparation reservoir 8, and the frequency is too high or too low to have a certain influence on the water discharge index of the electrolysis module. Therefore, by adjusting the concentration of the electrolytic solution in the electrolytic solution preparation reservoir 8, it is possible to ensure that the pulse frequency of the electrolytic solution supply pulse pump 10 is maintained in an appropriate range. Generally, the pulse frequency of the pulse pump 10 ranges from 10 to 110, and the preferred range is 30 to 60. The concentration of the electrolytic solution in the electrolytic solution preparation reservoir 8 ranges from 1% to 10%, which is an ideal range. It is 3% to 5%.

 The present invention can employ multiple electrolytic modules to work in parallel to increase the production per unit time of the oxidation potential water. The central control unit controls one or more of the parallel electrolysis modules to be turned on or off based on the level signal provided by the level sensing sensor device disposed in the acidic water reservoir. When the liquid level is low, the water consumption is large. At this time, multiple parallel electrolysis modules are started to work at the same time; when the liquid level is high, the water consumption is small, and the single electrolysis module is started at this time; when the liquid level is not changed, there is no water, and the water can be temporarily turned off. Electrolytic module. Specifically, a liquid level sensor may be disposed in the acidic water liquid storage device and the alkaline water liquid storage device, and the central control device calculates a rate of decrease or increase of liquid in each liquid storage device according to the liquid level signal, thereby determining the oxidation potential water. Consumption and consumption rate. Further, in order to avoid frequent opening and closing of the electrolytic module, the present invention may also be provided with an automatic or manual limiting device.

 On the other hand, in the present invention, the oxidation potential water and the softened water can be diluted according to a certain ratio, and the dilution ratio should ensure a reliable sterilization effect. At this time, the system of the present invention requires an electric potential water ratio adjusting device (see the schematic block diagram of Fig. 2B) which is connected to the acidic water liquid storage device and the filtering and softening device, and controls the flow detecting sensors disposed on the respective pipes. The device dilutes the demineralized water and the acidic water in proportion (diluted acidic water in the present embodiment, but may also dilute the alkaline water if necessary), and the diluted acidic water is sent to the disinfection device through the acidic water delivery device. Disinfect the individual equipment in the production process of liquid beverages. Further, since the dilution ratio of the acidic water required is different depending on the object to be disinfected, the above system of the present invention may have a plurality of potential water ratio ratio means for formulating acidic water of different ratios. By diluting the potential water required for disinfection, not only can the amount of water required for cleaning and disinfection be satisfied, but also a small amount of acidic water solution is required for dilution, which saves the cost of electrolysis and has certain economic benefits.

 Referring to Fig. 2C, for a place where there is no on-site electrolysis equipment, the dilution ratio can be made by supplying a potential water liquid solution and softened demineralized water. Since the electrolysis equipment is omitted, the overall cost of the disinfection system is reduced, and the cost is saved. This type of disinfection system without electrolysis equipment is generally suitable for use in distributed settings. In addition, the disinfection system of the distributed setting can also adopt the electrolysis device according to the actual situation. If the dispersed production site is large and the amount of water required for disinfection is large, the disinfection system shown in Fig. 2A or 2B may be used instead of the system shown in Fig. 2C.

According to an embodiment of the present invention, for various dilution ratio ratios, the liquid level sensor of the acid water ratio storage tank, the acidic water liquid physicochemical index detecting device, and the diluted ratio acidic water can be controlled by the central control device. The physical and chemical indicator detection device, the ratio of the softened water flow meter, the ratio of the data detected by the acid water flow meter, the acid water supply pump and the softened water supply pump are controlled to achieve different dilution ratios to achieve Disinfection of the same equipment. When using, only need to input the dilution ratio on the central control device, the controller can automatically inject a certain amount of acidic water and softened water according to the data information detected by each sensor to complete the required dilution ratio, and according to different equipment The disinfection requires automatic control of its cleaning and disinfection process.

 In accordance with an embodiment of the present invention, Figure 9 shows an illustrative dilution ratio flow chart. In step S10, the dilution of the acidic oxidation potential water is started. In step S20, the physical and chemical indicators of the acidic water in the acidic water storage tank 13 are determined based on the data measured by the acidic water original liquid physicochemical index detecting device 14, and the physical and chemical indicators after the desired acidic water dilution are determined. The desired diluted acidic water physicochemical index must have an effective disinfecting ability. The physical and chemical indicators can be determined by a large amount of experimental data in the previous period, for example, using different dilution ratios of acidic water for disinfecting different disinfecting objects. The experiment thus accumulates a range of physical and chemical indicators (diluted ratio range) for reliable disinfection of different disinfecting objects and a preferred physical and chemical index (preferred dilution ratio). The preferred physical and chemical indicators (preferred dilution ratio) are determined on the premise of ensuring the disinfection effect, taking into account the maximum water supply, optimal water supply, minimum electrolysis cost, and optimal electrolysis cost. The specific dilution ratio will be It is given in the following description. These data are stored in memory, which can be recalled by the central control unit 9 or recalculated based on new requirements. In general, it is determined in step 20 that the physical and chemical indicators after dilution with the preferred acidic water are employed.

 In step S30, the remaining volume of the acidic water ratio reservoir 18 is calculated based on the data detected by the acidic water ratio reservoir level sensor 17. The total volume of the acidic water ratio storage tank 18 is known. According to the liquid level data of the acidic water ratio storage tank level sensor 17, the volume of the existing liquid of the acidic water ratio storage tank 18 and the acidic water can be determined. The remaining volume of the reservoir 18 is matched.

 In step S40, according to the current detection value of the acid physicochemical index detecting device 19 of the dilution ratio (in order to improve the accuracy, it may be detected as many times as necessary, and the average value is taken) to determine the existing liquid of the acidic water ratio storage tank 18. Physical and chemical indicators. According to the acidic water physicochemical index in the acidic water storage tank 13, the physicochemical index of the existing liquid of the acidic water ratio storage tank 18, the volume of the existing liquid of the acidic water ratio storage tank 18, and the acidic water ratio storage tank 18 The remaining volume, and the parameters of the acidic water physicochemical index after dilution, calculate the dilution ratio of the acidic water. If the acidic water ratio storage tank 18 has a circulation loop, the parameters of the recycle backwater are also considered.

 In step S50, the volume of the acidic water liquid and the softened water are calculated based on the remaining volume of the acidic water ratio reservoir 18 and the dilution ratio of the acidic water.

 In step S60, the acidic water dilution ratio softening water supply pump 4 and the acidic water dilution ratio acid water supply pump 15 are started to supply the liquid to the acidic water ratio storage tank 18.

 In step S70, the acidic water dilution ratio softening water supply pump 4 and the acidic water dilution ratio acid water supply pump 15 are determined according to the flow rate data detected by the ratio softening water flow meter 5 and the ratio acid water flow meter 16. shut down.

 In step S80, the dilution ratio of the acidic water is automatically fine-tuned according to the detection value of the acid physicochemical index detecting device 19 of the dilution ratio (which may be detected as many times as necessary). The invention can monitor the physical and chemical indicators of the acidic water diluted in the acidic water ratio storage tank 18 in real time, and adjust the dilution ratio according to the difference between the detected index and the expected physical and chemical indicators determined in step 20. The flow returns to step S30.

 The above embodiment is merely an illustrative example, and the required dilution ratio can be achieved by simplification, recombination or addition of some new control elements for each step.

 In addition, a raw water constant pressure supply device can be provided on the pipeline for supplying the tap water to the system in the liquid beverage factory, thereby solving the problem of instability of the on-site water pressure.
