Description

Technical Field

[0001] The invention relates to the technical field of ice making, and in particular to a tube ice machine system for preparing multi-flavor solid tube ice and an ice making control method thereof. Background Art

[0002] Tube ice machine is a kind of ice making machine, named because the ice cubes it makes are in the shape of tubes. With the improvement of people's living standards, the quality requirements for ice cubes are getting higher and higher, so the demand for solid tube ice is increasing. Based on this, our company has developed a tube ice machine that can make solid tube ice. Refer to the tube ice machine system described in patent publication number CN109269173A, which is mainly composed of a compressor, a condenser, a liquid storage tank, an expansion valve, an evaporator, and other components. Among them, a number of ice-making tubes are arranged in the evaporator. Its ice-making process includes the following three processes: Ice making: The low-temperature and low-pressure gaseous refrigerant is transformed into a high-temperature and high-pressure gaseous refrigerant by the compressor and then into a medium-temperature and high-pressure gas-liquid mixture by the condenser and flows into the liquid storage tank. After that, it is transformed into a low-temperature liquid refrigerant by the expansion valve and flows into the evaporator. The liquid raw material in the ice-making pipe exchanges heat with the low-temperature liquid refrigerant, thus gradually forming ice.

[0003] De-icing: The passage between the condenser and the liquid storage tank is disconnected, and the passage between the liquid storage tank and the expansion valve is disconnected. The medium-temperature refrigerant in the liquid storage tank is directly transported to the evaporator. At this time, the temperature in the evaporator rises, causing the solid tube ice to gradually melt. The refrigerant flowing out of the evaporator is transported to the compressor, and after compression, it is transported to the condenser and then to the liquid storage tank. The above steps are repeated until the solid tube ice is separated from the ice-making tube.

[0004] Ice cutting: When the solid tube ice is separated from the ice-making tube, the ice cutting device cuts the solid tube ice into sections.

[0005] In the field of frozen food production, multi-flavored ice cubes are a reflection of the increasingly diversified market demand. As consumers' requirements for food taste and quality increase, multi-flavored ice cubes are widely welcomed for their unique taste and diverse choices. However, traditional ice cube production technology is often limited to a single flavor and cannot meet the market demand for diversified flavors. Therefore, there is room for improvement. Summary of the invention

[0006] In order to realize the production of tube ice with multiple flavors and enable the tube ice machine to meet the market demand for diversified flavors, the present application provides a tube ice machine system for preparing solid tube ice with multiple flavors and an ice making control method thereof.

[0007] In a first aspect, the present application provides a tube ice machine system for preparing solid tube ice with multiple flavors, which adopts the following technical solutions: A tube ice machine system for preparing multi-flavor solid tube ice, comprising a compressor, a condenser, a liquid storage tank, an expansion valve, an evaporator, a heat exchanger, an ice cutting device, a raw material box, a liquid supply pump and a main control module, wherein the top of the evaporator is connected with an air return pipe, the evaporator is provided with a plurality of vertically arranged ice-making pipes, the liquid supply pump is used to pump liquid raw materials in the raw material box into the ice-making pipes, the raw material box is provided with a plurality of liquid storage boxes for storing liquid raw materials of different flavors, and the evaporator is provided with a pressure gauge; When making ice, the compressor, condenser, liquid storage tank, expansion valve, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop, the liquid supply pump pumps liquid raw materials of different flavors in the raw material box to the ice-making pipe of the evaporator, and the main control module adjusts the ice-making parameters of each device according to the liquid raw materials of different flavors; During deicing, the compressor, liquid storage tank, evaporator, air return pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop.

[0008] By adopting the above technical scheme, when making ice, the present application connects the compressor, condenser, liquid storage tank, expansion valve, evaporator, return air pipe, heat exchanger and compressor in sequence through pipelines to form a closed loop, and the liquid supply pump pumps the liquid raw materials of different flavors in the raw material box into the ice-making pipe of the evaporator. The main control module adjusts the appropriate ice-making parameters of each device in the ice-making system according to the liquid raw materials of different flavors pumped into the ice-making pipe, such as the evaporation temperature, the pumping amount and pressure of the liquid raw materials, etc. The low-temperature and low-pressure liquid refrigerant is added into the evaporator, thereby exchanging heat with the liquid raw material in the ice-making pipe. The temperature of the liquid raw material in the ice-making pipe decreases and gradually condenses into ice, and the low-temperature and low-pressure liquid refrigerant It evaporates into gaseous refrigerant and passes through the return air pipe. The heat exchanger then heats the gaseous refrigerant to eliminate the possibility of liquid refrigerant in the gaseous refrigerant. The gaseous refrigerant flows back to the compressor and circulates repeatedly until all the liquid raw materials in the ice-making pipe are condensed into ice, so that the tube ice machine system can make tube ice with multiple flavors in the ice-making pipe, so that the tube ice machine can meet the market demand for diversified flavors. When defrosting, the compressor, liquid storage tank, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop. The high-temperature gaseous refrigerant is passed into the evaporator. The temperature in the evaporator gradually increases, causing the surface of the solid tube ice to gradually melt, completing the production of tube ice with multiple flavors.

[0009] Optionally, a pressure gauge is provided on the evaporator, and a reading of the pressure gauge is obtained in real time during the defrosting process. When the reading of the pressure gauge exceeds a defrosting pressure threshold, the compressor is operated at a reduced frequency until the defrosting threshold is reached.

[0010] By adopting the above technical solution, since the heat required for melting the solid tube ice is getting less and less during the deicing process, if the same amount of gaseous refrigerant is continuously introduced into the evaporator, the gas-liquid mixed refrigerant flowing back to the compressor will increase, which is easy to cause oil throwing or liquid hammering in the compressor, thereby affecting the service life of the compressor. Therefore, the present application obtains the reading of the pressure gauge in real time during the deicing process. When the reading of the pressure gauge exceeds the deicing pressure threshold, it indicates that the temperature in the evaporator has increased, that is, it indicates that excess gaseous refrigerant has been filled into the evaporator. Therefore, the control module controls the compressor to reduce the frequency operation, so that the flow rate of the gaseous refrigerant added to the evaporator is reduced, thereby reducing the amount of gas-liquid mixed refrigerant flowing back to the compressor, thereby reducing the oil throwing or liquid hammering of the compressor, which is beneficial to extending the service life of the compressor. At the same time, by setting a heat exchanger, the gas-liquid mixed refrigerant discharged from the evaporator to the return air pipe needs to pass through the heat exchanger for heat exchange, thereby reducing the proportion of liquid refrigerant in the gas-liquid mixed refrigerant, and further reducing the possibility of oil throwing or liquid hammering in the compressor.

[0011] Optionally, during the ice-making process, when the reading of the pressure gauge exceeds the refrigeration pressure threshold, the compressor increases its frequency of operation.

[0012] By adopting the above technical solution, during the ice-making process, if the amount of low-temperature gas-liquid mixed refrigerant introduced into the evaporator is small, the ice-making efficiency is low, and the temperature and pressure in the evaporator are high at this time. Therefore, the present application obtains the reading of the pressure gauge in real time through the refrigeration pressure threshold. When the reading of the pressure gauge exceeds the refrigeration pressure threshold, it means that the temperature in the evaporator is high and the amount of refrigerant filled into the evaporator is small. Therefore, the control module controls the compressor to increase the frequency of operation, so that the flow rate of the gas-liquid mixed refrigerant is accelerated, thereby improving the heat exchange efficiency, and then improving the refrigeration efficiency and shortening the ice-making time.

[0013] Optionally, a liquid supply pipe is connected between the water inlet end of the liquid supply pump and the raw material box, and a first flow meter is arranged on the liquid supply pipe; an overflow pipe is connected between the top of the raw material box and the top of the evaporator, and a second flow meter is arranged on the overflow pipe; the readings of the first flow meter are compared with the second flow meter in real time during the ice-making process; when the first ice-making threshold is reached, if the difference between the readings of the first flow meter and the second flow meter is within the anti-cracking threshold, the compressor is operated at a reduced frequency until the second ice-making threshold is reached; otherwise, an alarm message is issued.

[0014] By adopting the above technical solution, since the refrigerant flows in from one end of the evaporator and flows out from the other end of the evaporator, the end of the ice-making tube close to the feed end of the evaporator will first contact the refrigerant. At this time, the temperature of the refrigerant is the lowest, causing the liquid raw material in the ice-making tube that first exchanges heat with the refrigerator to freeze first, so that the liquid raw material at the bottom of the ice-making tube freezes while the liquid raw material at the top is not completely frozen. During the ice-making process, the heat exchange required by the liquid raw material is continuously reduced. If the same amount of refrigerant is continuously introduced, the temperature in the evaporator will continue to decrease, and the pressure will also continue to decrease. The solid tube ice that has been condensed is easy to crack in a low-temperature environment where the temperature continues to drop, which not only makes subsequent de-icing difficult, but also poor ice-making quality. Therefore, by setting an overflow pipe, a first flowmeter and a second flowmeter, as the ice-making time increases, the reading of the second flowmeter will gradually increase and eventually equal the reading of the first flowmeter. During this process, the readings of the first flow meter and the second flow meter are compared in real time. When the ice-making time reaches the first ice-making threshold, if the difference between the reading of the first flow meter and the reading of the second flow meter is within the anti-cracking threshold, it means that the liquid raw material at the bottom of the ice-making pipe is about to be completely condensed or has been completely condensed. At this time, the control module controls the compressor to reduce the frequency until the second ice-making threshold is reached, so that the refrigeration capacity charged into the evaporator is reduced, eliminating the possibility of cracking of the solid tube ice in the ice-making pipe, which is not only convenient for subsequent de-icing, but also conducive to improving the quality of ice making. Correspondingly, if the difference between the readings of the first flow meter and the second flow meter is not within the anti-cracking threshold, it means that a certain link or component of the refrigeration system is damaged, and an alarm message is issued to remind the staff to avoid causing greater losses.

[0015] In a second aspect, the present application provides an ice making control method for the tube ice machine system for preparing multi-flavor solid tube ice, which adopts the following technical solution: An ice making control method for a tube ice machine system for preparing solid tube ice with multiple flavors, the ice making control method for a tube ice machine system for preparing solid tube ice with multiple flavors comprising the steps of: Acquiring information of liquid raw materials pumped into the ice-making pipe, and determining ice-making parameters based on the liquid raw material information; Setting parameters of various devices involved in the ice making process in the tube ice machine system based on the ice making parameters; According to the ice-making parameters, a solid tube ice image in the ice-making tube is acquired in real time, and a parameter control instruction is generated based on the solid tube ice image; In response to the parameter control instruction, an ice-making adjustment parameter is obtained, and parameters of various devices in the ice-making process are adjusted according to the ice-making adjustment parameter.

[0016] By adopting the above technical scheme, in the process of preparing multi-flavor tube ice, in order to make solid tube ice, the liquid raw material information pumped into the ice-making tube is used to analyze the liquid raw materials of different flavors, and the corresponding ice-making parameters are determined according to the liquid raw materials of different flavors, such as evaporation temperature, pumping volume and pressure of the liquid raw materials, etc. According to the ice-making parameters, the corresponding parameters are set for the equipment involved in the ice-making process, and the production of multi-flavor tube ice begins. During the production process, the tube ice machine system will produce layers of tube ice of different flavors in the ice-making tube toward the center of the ice-making tube, and according to the ice-making parameters, the solid tube ice image in the current ice-making tube is obtained, that is, the current ice-making tube image. The tube ice image of the inner layer is used to generate parameter control instructions based on the tube ice image, so as to adjust the ice-making parameters for the tube ice of the next flavor in advance. Because different flavors of liquid raw materials require different ice-making parameters, and the previous flavor has already frozen, the ice-making parameters of the next flavor need to enable the tube ice made of this flavor to be able to merge with the tube ice of the previous flavor, so as to produce concentric multi-flavor solid tube ice. The parameter control instructions are responded to to obtain ice-making adjustment parameters. The ice-making adjustment parameters refer to the specific values ​​for adjusting the parameters of the equipment in the ice-making process. The parameters of each equipment involved in the ice-making process are adjusted according to the ice-making adjustment parameters to improve the ice-making effect.

[0017] In a preferred example, the present application may be further configured as follows: the step of obtaining the liquid raw material information pumped into the ice-making pipe and determining the ice-making parameters based on the liquid raw material information specifically includes: Acquire the type of liquid raw material based on the liquid raw material information; The liquid raw material type is input into a preset raw material parameter ratio database, in which a mapping table between raw material types and ice-making parameters is provided, and the ice-making parameters are determined based on the liquid raw material type.

[0018] By adopting the above technical solution, the liquid raw material pumped into the ice-making pipe is analyzed to identify the type of liquid raw material currently pumped into the ice-making pipe, and the obtained liquid raw material type is input into a preset raw material parameter ratio database. The raw material parameter ratio database is provided with a mapping table between liquid raw material type and ice-making parameters. The corresponding ice-making parameters are determined according to the liquid raw material type, and the ice-making parameters can be automatically set. Appropriate parameters are configured for tube ice with different flavors, thereby improving the ice-making effect.

[0019] In a preferred example, the present application may be further configured as follows: acquiring a solid tube ice image in an ice-making tube in real time according to the ice-making parameters, and generating a parameter control instruction based on the solid tube ice image, specifically including: acquiring an image of the tube ice of each flavor based on the solid tube ice image, and acquiring an ice making state of the current flavor based on the image of the tube ice of each flavor; A parameter control instruction is generated according to the ice making state of the current flavor and the liquid raw material information of the next flavor.

[0020] By adopting the above technical solution, during the production process, the tube ice machine system will make layers of tube core ice of different flavors in the ice-making tube toward the center of the ice-making tube, use the solid tube ice image to determine the ice-making state of the current flavor layer, and generate parameter control instructions based on the ice-making state of the current flavor layer and the liquid raw material information of the next flavor, so that the tube ice made of this flavor can be integrated with the tube ice of the previous flavor, thereby being able to produce concentric multi-flavor solid tube ice.

[0021] In a preferred example, the present application may be further configured as follows: after obtaining the first ice-making adjustment parameter in response to the parameter control instruction and adjusting the parameters of each device in the ice-making process according to the first ice-making adjustment parameter, the ice-making control method of the tube ice machine system for preparing multi-flavor solid tube ice may further include: Acquire refrigerant mass data in the gas return pipeline, and acquire ratio data of gaseous refrigerant and liquid refrigerant based on the refrigerant mass data; A compressor control instruction is generated according to the ratio data of the gaseous refrigerant and the liquid refrigerant, compressor suction pressure adjustment data is acquired in response to the compressor control instruction, and the suction pressure of the compressor is adjusted based on the compressor suction pressure adjustment data.

[0022] By adopting the above technical solution, when the refrigeration system is in the ice-making process, the refrigerant quality data in the return air pipeline is obtained in real time through the steam quality sensor installed on the return air pipeline, and the proportion of liquid refrigerant in the gaseous refrigerant is obtained according to the refrigerant quality data. According to the proportion of liquid refrigerant in the gaseous refrigerant, a corresponding compressor control instruction is generated, and the suction pressure of the compressor is controlled in response to the compressor control instruction to prevent the liquid in the return air from failing to completely evaporate in the heat exchanger and returning to the compressor to cause damage to the compressor.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the present application, when making ice, the compressor, condenser, liquid storage tank, expansion valve, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop. The liquid supply pump pumps the liquid raw materials of different flavors in the raw material box into the ice-making pipe of the evaporator. The main control module adjusts and controls appropriate ice-making parameters for each device of the ice-making system according to the liquid raw materials of different flavors pumped into the ice-making pipe, such as evaporation temperature, pumping volume and pressure of the liquid raw materials, etc. The low-temperature and low-pressure liquid refrigerant is replenished into the evaporator, thereby exchanging heat with the liquid raw material in the ice-making pipe. The temperature of the liquid raw material in the ice-making pipe decreases and gradually condenses into ice, and the low-temperature and low-pressure liquid refrigerant evaporates into The gaseous refrigerant passes through the return air pipe, and then the heat exchanger heats the gaseous refrigerant to eliminate the possibility of liquid refrigerant in the gaseous refrigerant. The gaseous refrigerant flows back to the compressor and circulates repeatedly until all the liquid raw materials in the ice-making pipe are condensed into ice, so that the tube ice machine system can make tube ice with multiple flavors in the ice-making pipe, so that the tube ice machine can meet the market demand for diversified flavors. When defrosting, the compressor, liquid storage tank, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop, and the high-temperature gaseous refrigerant is passed into the evaporator. The temperature in the evaporator gradually increases, causing the surface of the solid tube ice to gradually melt, completing the production of tube ice with multiple flavors. 2. During the defrosting process, the heat required to melt the solid tube ice is getting smaller and smaller. If the same amount of gaseous refrigerant is continuously introduced into the evaporator, the gas-liquid mixed refrigerant flowing back to the compressor will increase, which may easily cause the compressor to have oil throwing or liquid hammering, thus affecting the service life of the compressor. Therefore, the present application obtains the pressure gauge reading in real time during the defrosting process. When the pressure gauge reading exceeds the defrosting pressure threshold, it indicates that the temperature in the evaporator has increased, that is, it indicates that excess gaseous refrigerant has been filled into the evaporator. Therefore, the control module controls the compressor to reduce the frequency of operation, so that the flow rate of the gaseous refrigerant added to the evaporator is reduced, thereby reducing the amount of gas-liquid mixed refrigerant flowing back to the compressor, thereby reducing the oil throwing or liquid hammering of the compressor, which is beneficial to extending the service life of the compressor. At the same time, by setting a heat exchanger, the gas-liquid mixed refrigerant discharged from the evaporator to the return pipe needs to pass through the heat exchanger for heat exchange, thereby reducing the proportion of liquid refrigerant in the gas-liquid mixed refrigerant, and further reducing the possibility of oil throwing or liquid hammering in the compressor. 3. In the process of preparing multi-flavor tube ice, in order to make solid tube ice, the liquid raw material information pumped into the ice-making tube is used to analyze the liquid raw materials of different flavors, and the corresponding ice-making parameters are determined according to the liquid raw materials of different flavors, such as the evaporation temperature, the pumping amount and pressure of the liquid raw materials, etc. According to the ice-making parameters, the corresponding parameters are set for the equipment involved in the ice-making process, and the production of multi-flavor tube ice begins. During the production process, the tube ice machine system will make layers of tube ice of different flavors in the ice-making tube toward the center of the ice-making tube. According to the ice-making parameters, the solid tube ice image in the current ice-making tube is obtained, that is, the current layer of the ice in the current ice-making tube. Tube ice image, generating parameter control instructions according to the tube ice image, so as to adjust the ice-making parameters for the tube ice of the next flavor in advance, because different flavors of liquid raw materials require different ice-making parameters, and the previous flavor has been frozen, so the ice-making parameters of the next flavor need to make the tube ice made of the new flavor able to merge with the tube ice of the previous flavor, so as to make concentric multi-flavor solid tube ice, responding to the parameter control instruction to obtain ice-making adjustment parameters, ice-making adjustment parameters refer to specific values ​​for adjusting the parameters of the equipment in the ice-making process, and adjusting the parameters of each equipment involved in the ice-making process according to the ice-making adjustment parameters to improve the ice-making effect; 4. The evaporator liquid level sensed by the liquid level sensor on the evaporator is used to control the flow of the two control valve groups and the throttle valve group, thereby realizing the control of the refrigerant liquid level in the evaporator. Because the gas-liquid separator is provided with a lower liquid pipeline and adopts a high-efficiency gas-liquid separator with multiple gas-liquid separation means, the gaseous refrigerant from the evaporator outlet to the evaporator can be allowed to carry a certain amount of liquid, thus realizing the function of a higher liquid level in the evaporator, meeting the needs of a half-full liquid system; gravity liquid supply to the evaporator is realized through the liquid supply pipeline of the gas-liquid separator, and the two control valve groups, the throttle valve group and the control valve are controlled by the liquid level sensor on the gas-liquid separator to realize liquid level control in the gas-liquid separator, meeting the needs of a full liquid system.

A second flow meter 16 is provided at the water inlet end of the overflow pipe 15, and the second flow meter 16 is electrically connected to the main control module.

[0028] When making ice, the compressor, condenser, liquid storage tank, expansion valve, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipes to form a closed loop. The liquid supply pump pumps liquid raw materials of different flavors in the raw material box to the ice-making pipe of the evaporator. The main control module adjusts the ice-making parameters of each device according to the liquid raw materials of different flavors. During the ice-making process, when the pressure gauge reading exceeds the refrigeration pressure threshold, the compressor increases its frequency.

[0029] During defrosting, the compressor, liquid storage tank, evaporator, air return pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop.

[0030] The implementation principle of a tube ice machine system for preparing solid tube ice with multiple flavors in an embodiment of the present application is as follows: when making ice, the compressor, condenser, liquid storage tank, expansion valve, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop, and the liquid supply pump pumps liquid raw materials of different flavors in the raw material box into the ice-making pipe of the evaporator. The main control module adjusts appropriate ice-making parameters for each device of the ice-making system according to the liquid raw materials of different flavors pumped into the ice-making pipe, such as evaporation temperature, pumping volume and pressure of the liquid raw material, and low-temperature and low-pressure liquid refrigerant is added into the evaporator, thereby exchanging heat with the liquid raw material in the ice-making pipe. The temperature of the liquid raw material in the ice-making pipe decreases and gradually condenses into ice, and the low-temperature The low-pressure liquid refrigerant evaporates into gaseous refrigerant and passes through the return air pipe. The heat exchanger then heats the gaseous refrigerant to eliminate the possibility of liquid refrigerant in the gaseous refrigerant. The gaseous refrigerant flows back to the compressor and circulates repeatedly until all the liquid raw materials in the ice-making pipe are condensed into ice, so that the tube ice machine system can make tube ice with multiple flavors in the ice-making pipe, so that the tube ice machine can meet the market demand for diversified flavors. When defrosting, the compressor, liquid storage tank, evaporator, return air pipe, heat exchanger and compressor are connected in sequence through pipelines to form a closed loop. The high-temperature gaseous refrigerant is passed into the evaporator. The temperature in the evaporator gradually increases, causing the surface of the solid tube ice to gradually melt, completing the production of tube ice with multiple flavors.

[0031] In one embodiment, if Figure 2 As shown, the present application also discloses an ice making control method for a tube ice machine system for preparing solid tube ice with multiple flavors. The ice making control method for a tube ice machine system for preparing solid tube ice with multiple flavors specifically comprises the following steps: S10: obtaining information of liquid raw materials pumped into the ice-making pipe, and determining ice-making parameters based on the liquid raw material information.

Because the ice-making parameters required for liquid raw materials of different flavors are different, and the previous flavor has already frozen, the ice-making parameters of the next flavor need to enable the tube ice made of the new flavor to be able to merge with the tube ice of the previous flavor, so as to produce concentric multi-flavor solid tube ice.

During the production process, the tube ice machine system will produce layers of tube ice of different flavors in the ice-making tube toward the center of the ice-making tube.

[0043] In one embodiment, if Figure 4 As shown, in step S30, that is, according to the ice-making parameters, a solid tube ice image in the ice-making tube is acquired in real time, and a parameter control instruction is generated based on the solid tube ice image, specifically including: S31: acquiring an image of the tube ice of each flavor based on the solid tube ice image, and acquiring an ice-making state of the current flavor based on the image of the tube ice of each flavor.

[0044] S32: Generate parameter control instructions according to the ice-making state of the current flavor and the liquid raw material information of the next flavor.

[0045] Specifically, during the production process, the tube ice machine system will make layers of tube core ice of different flavors in the ice-making tube toward the center of the ice-making tube, use the solid tube ice image to determine the ice-making status of the current flavor layer, and generate parameter control instructions based on the ice-making status of the current flavor layer and the liquid raw material information of the next flavor, so that the tube ice made of this flavor can be integrated with the tube ice of the previous flavor, thereby producing concentric multi-flavor solid tube ice.

[0046] In one embodiment, if Figure 5 As shown, after step S40, that is, after obtaining the first ice-making adjustment parameter in response to the parameter control instruction and adjusting the parameters of each device in the ice-making process according to the first ice-making adjustment parameter, the ice-making control method of the tube ice machine system for preparing multi-flavor solid tube ice also includes: S50: Acquire refrigerant mass data in the return air pipeline, and acquire ratio data of gaseous refrigerant and liquid refrigerant based on the refrigerant mass data.

[0047] S60: Generate a compressor 1 control instruction according to the ratio data of the gaseous refrigerant and the liquid refrigerant, obtain compressor 1 suction pressure adjustment data in response to the compressor 1 control instruction, and adjust the suction pressure of the compressor 1 based on the compressor 1 suction pressure adjustment data.

[0048] Specifically, when the refrigeration system is in the ice-making process, the refrigerant quality data in the return air pipeline is obtained in real time through the steam quality sensor installed on the return air pipeline, and the proportion of liquid refrigerant in the gaseous refrigerant is obtained according to the refrigerant quality data. According to the proportion of liquid refrigerant in the gaseous refrigerant, a corresponding compressor 1 control instruction is generated, and the suction pressure of the compressor 1 is controlled in response to the compressor 1 control instruction to prevent the liquid in the return air from being unable to completely evaporate in the heat exchanger 5 and returning to the compressor 1 to cause damage to the compressor 1.
