Description

[0002] Under current dairy production conditions, filling machines employ varying methods to sterilize raw materials, auxiliary materials, and packaging. Typically, disinfectant must be injected into the filling machine to achieve sterilization.

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] The technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Under current dairy production conditions, filling machines employ varying methods to sterilize raw materials, auxiliary materials, and packaging. Typically, disinfectant must be injected into the filling machine to achieve sterilization. Currently, hydrogen peroxide is the most commonly used disinfectant, sterilizing through the oxidation reaction of H2O2. This demonstrates that hydrogen peroxide is the most fundamental factor in ensuring the complete sterilization of raw materials and packaging equipment, and is the most important guarantee for ensuring product quality.

[0047] Based on dairy production conditions, a refractometer is usually used to measure the concentration of disinfectant in the disinfectant tank of the filling machine. Then, when the monitored concentration is lower than a fixed concentration value, the disinfectant is replenished until the monitored concentration is not lower than the fixed concentration value. The addition is stopped. This disinfectant replenishment method has poor accuracy. However, if the concentration is set too high, it will cause waste of resources, and if it is set too low, it will not meet the product disinfection requirements.

[0048] Based on the above problems, the embodiment of the present invention provides a method for controlling the replenishment of disinfectant in a filling machine, such as Figure 1 As shown, the filling machine includes: a filling machine body 1 and a controller 2, wherein a peristaltic pump 3 is provided at the disinfectant replenishing end of the filling machine body 1, and the peristaltic pump 3 replenishes the external disinfectant into the interior of the filling machine. The peristaltic pump 3 is a fixed-frequency peristaltic pump.

[0049] like Figure 2 As shown, the filling machine disinfectant replenishment control method provided by the embodiment of the present invention is applied to Figure 1 The controller 2 shown specifically includes the following steps:

[0050] Step S101: Obtain the target concentration value and target capacity of the disinfectant in the filling machine.

[0051] Among them, the target concentration value is the target concentration value determined by the filling machine when producing a certain product based on the product's requirements for disinfectant concentration. The target capacity is the fixed volume value always maintained by the disinfectant container used to hold the filling machine during operation, such as the hydrogen peroxide in the hydrogen peroxide tank. It should be noted that in this embodiment of the present invention, the fluctuation of the total amount of disinfectant in the hydrogen peroxide tank in the filling machine is negligible.

[0052] Step S102: monitoring the disinfectant replenishment signal sent by the filling machine, obtaining the current concentration value corresponding to the current disinfectant replenishment signal, the previous concentration value corresponding to the previous disinfectant replenishment signal, and the previous disinfectant replenishment amount.

[0053] Specifically, when the filling machine detects that the concentration of disinfectant in the filling machine is lower than a certain value, it triggers a disinfectant refill signal. At this time, the concentration of the disinfectant at this time can be monitored by a concentration monitoring device installed inside the filling machine, such as a refractometer. The disinfectant is then refilled and the amount of disinfectant refilled is recorded.

[0054] Step S103: Calculate the current amount of disinfectant to be replenished based on the target concentration value, the current concentration value and the target capacity.

[0055] Specifically, the current amount to be replenished can be calculated by multiplying the difference between the target concentration value and the current concentration value by the target capacity.

[0056] Step S104: Based on the target concentration value, the previous concentration value and the last disinfectant replenishment amount, the current amount to be replenished is corrected to determine the target replenishment amount.

[0057] Specifically, in order to eliminate the error in the last disinfectant replenishment, the current amount to be replenished is corrected by using the relevant parameters of the last disinfectant replenishment, so as to dynamically eliminate the replenishment error and improve the accuracy of disinfectant replenishment.

[0058] Step S105: Based on the target replenishment amount, the peristaltic pump of the filling machine is controlled to replenish the disinfectant.

[0059] Specifically, the peristaltic pump is controlled to start several times until the target replenishment amount is reached to complete the replenishment of the disinfectant.

[0060] By executing the above steps, the disinfectant replenishment control method for a filling machine provided by an embodiment of the present invention provides a method for replenishing disinfectant for a filling machine by installing a fixed-frequency peristaltic pump at the disinfectant replenishment port of the filling machine. This method uses the peristaltic pump to replenish external disinfectant into the filling machine. Furthermore, to avoid errors in replenishing the disinfectant by the fixed-frequency peristaltic pump, the replenishment amount is corrected in real time, thereby ensuring accurate disinfectant replenishment and avoiding waste of resources. This method can be applied to products with strict requirements on disinfectant concentration.

[0061] Specifically, in one embodiment, obtaining the last replenishment amount of disinfectant in the above step S102 specifically includes the following steps:

[0062] Step S201: obtaining the number of starts of the peristaltic pump between the last disinfectant replenishment signal and the current disinfectant replenishment signal.

[0063] Specifically, when the filling machine sends out disinfectant replenishment signals twice in a row, the amount of disinfectant replenished between the two disinfectant replenishment signals is the amount of hydrogen peroxide replenished to the filling machine from the outside by the peristaltic pump, and the amount of disinfectant replenishment is determined by monitoring the number of times the peristaltic pump is started.

[0064] Step S202: Calculate the last disinfectant replenishment amount of the filling machine based on the single injection volume and the number of starts of the peristaltic pump.

[0065] Specifically, since the peristaltic pump is a fixed-frequency peristaltic pump, the single injection volume of hydrogen peroxide is fixed and can be determined in advance based on the current actual production conditions. For example, the peristaltic pump is driven by a hydrogen peroxide replenishment signal (contactor energization), and the product of the number of activations and the word injection volume is the disinfectant replenishment volume.

[0066] In addition, based on the dairy production conditions (the flow monitoring in dairy production is rough and fluctuates, and does not need to be accurate to the second or milliliter level), the anomalies that occur during the addition process of the hydrogen peroxide system can be processed through signal delay and filtering, thereby further improving the accuracy of disinfectant replenishment control.

[0067] Specifically, in one embodiment, the above step S104 specifically includes the following steps:

[0068] Step S301: determining a replenishment amount correction value based on the target concentration value, the previous concentration value, and the previous disinfectant replenishment amount.

[0069] Specifically, the above step S301 specifically includes: determining the previous amount to be replenished based on the target concentration value and the previous concentration value; calculating the deviation based on the previous amount to be replenished and the previous disinfectant replenishment amount; determining the replenishment amount correction value based on the deviation and its corresponding preset weight coefficient.

[0070] Step S302: Determine the target replenishment amount based on the current amount to be replenished and the replenishment amount correction value.

[0071] Specifically, the target supplement amount is determined according to the following formula (1):

[0072] V=[(C-C1)V1-L1]K1+[(C-C2)V1]K2 (1)

[0073] Where V represents the target replenishment volume, C represents the target concentration value, C1 represents the previous concentration value, C2 represents the current concentration value, V1 represents the target capacity, and K1 and K2 represent preset weight coefficients. Specifically, the values of K1 and K2 can be determined based on manual experience or by analyzing historical data from the filling machine. This will not be elaborated here.

[0074] Specifically, in one embodiment, the above step S105 specifically includes the following steps:

[0075] Step S401: Calculate the target number of operations of the peristaltic pump based on the single injection volume and the target replenishment volume of the peristaltic pump.

[0076] Step S402: Control the peristaltic pump to replenish the disinfectant according to the target number of actions.

[0077] Specifically, the target replenishment volume divided by the single injection volume gives the target number of peristaltic pump actuations. In practical applications, to ensure that the disinfectant meets product concentration requirements, if the calculated result is less than 1, replenishment is performed as 1. For example, if the calculated result is 3.4, the target number of actuations is 4, thus ensuring that product disinfection requirements are met.

[0078] Specifically, in one embodiment, the above-mentioned filling machine disinfectant replenishment control method further includes the following steps:

[0079] Step S106: When the filling machine sends a disinfectant replenishment signal for the first time, based on the current amount to be replenished, the peristaltic pump of the filling machine is controlled to replenish the disinfectant.

[0080] Specifically, when the disinfectant needs to be replenished for the first time during the operation of the filling machine, since the peristaltic pump has not yet started working, there is no replenishment error caused by the peristaltic pump action. Therefore, the disinfectant can be replenished directly according to the current amount to be replenished, thereby improving the working efficiency of the filling machine.

[0081] Since the hydrogen peroxide replenishment signal is determined by the filling machine's concentration, an alarm is triggered if the concentration falls below the standard range. That is, during the program cycle, if a replenishment signal is received, the peristaltic pump will operate once. However, because the power frequency pump replenishes the same amount each time, there is a discrepancy in the final hydrogen peroxide content between replenishments. Furthermore, hydrogen peroxide needs to be drained and replaced after a certain period of circulation, and some hydrogen peroxide is discharged with the diluent, affecting the accurate measurement of hydrogen peroxide consumption.

[0082] Based on current dairy production conditions, the amount of hydrogen peroxide added can be accurately measured using existing concentration meters. This is particularly applicable when peristaltic pumps are used to pump liquids and the storage of liquids in irregularly shaped buffer containers is required.

[0083] The filling machine disinfectant replenishment control method provided by the embodiment of the present invention has a stable data measurement for the hydrogen peroxide concentration and tries to control the stability of the concentration data. When using low concentration standard or low liquid level standard measurement, there is a certain error in the last replenishment of the peristaltic pump due to the fixed replenishment amount. The above formula (1) is used for measurement verification to eliminate the measurement error.

[0084] Through the filling machine disinfectant replenishment control method, the stable control of hydrogen peroxide concentration for metering is introduced. At the same time, the original liquid level and concentration control are changed to the pumping frequency of the output peristaltic pump, and the program counting frequency is executed; in addition, the current addition amount calculates the error of the last addition amount (there is a certain error, but the error is fitted to a certain extent through the weight coefficient K1 to make the error within the controllable range. Each addition amount will take the last addition error into consideration and eliminate it, thus achieving more accurate metering); each time hydrogen peroxide is added, when the concentration and liquid level are low, the difference between the existing hydrogen peroxide concentration and the target concentration is measured, and the required hydrogen peroxide amount is converted by a fixed water tank volume and coupled with a certain weight coefficient K2. The last error is integrated for a systematic control, and a closed-loop control circuit is formed in this way.

[0085] By executing the above steps, the disinfectant replenishment control method for a filling machine provided by an embodiment of the present invention provides a method for replenishing disinfectant for a filling machine by installing a fixed-frequency peristaltic pump at the disinfectant replenishment port of the filling machine. This method uses the peristaltic pump to replenish external disinfectant into the filling machine. Furthermore, to avoid errors in replenishing the disinfectant by the fixed-frequency peristaltic pump, the replenishment amount is corrected in real time, thereby ensuring accurate disinfectant replenishment and avoiding waste of resources. This method can be applied to products with strict requirements on disinfectant concentration.
