Description

Technical Field

[0001] The invention relates to the technical field of temperature control, and in particular to a novel chocolate tempering machine. Background Art

[0002] A chocolate tempering machine is a food processing equipment used to control the temperature of chocolate slurry. The temperature control inside the chocolate tempering machine can prevent the chocolate slurry from solidifying, and the output chocolate slurry can be controlled at a preset temperature according to actual processing needs. Therefore, a chocolate tempering machine is an indispensable equipment in the processing and production of chocolate-related foods.

[0003] The internal temperature control mechanism of the chocolate tempering machine in the prior art is mostly composed of an electric heating module, which is arranged along the chocolate slurry conveying pipeline. The temperature of the electric heating module is controlled to directly complete the tempering operation of the chocolate slurry during the conveying process. The heat generated by the electric heating module directly acts on the chocolate slurry through the pipe wall. Although the heat conduction efficiency can be guaranteed, it will lead to uneven temperature control. Under initial heating, the temperature of the pipe wall close to the electric heating module will be significantly higher than the temperature of the pipe wall on the other side, affecting the uniformity of the temperature control of the chocolate slurry in the pipeline. In addition, using the electric heating module to directly temper the chocolate slurry to a preset temperature will cause a sudden change in the temperature of the chocolate slurry, thereby affecting its quality.

By gradually changing the temperature, the sudden temperature change during the tempering process of the chocolate slurry can be avoided to affect its quality, and the tempering effect of the chocolate slurry during the conveying process is improved to a certain extent. At the same time, by wrapping the tempering chamber filled with circulating tempering water flow on the outside of the conveying pipe, the device can heat and regulate the chocolate slurry in a water bath heating manner, which can effectively ensure the stability and uniformity of the temperature control in the tempering area, thereby making the tempering of the chocolate slurry more stable and uniform; 2. In the present invention, by fixing the guide plate with a spiral structure in the temperature control chamber, the water flow circulating in the temperature control chamber can be guided, so that the temperature control water flow flows in the temperature control chamber in a unidirectional and orderly spiral shape, which is conducive to further improving the uniformity of the temperature control water flow in the temperature control chamber to the chocolate slurry in the conveying pipe. At the same time, by setting the flow direction of the temperature control water flow in the temperature control chamber to be opposite to the movement direction of the chocolate slurry in the corresponding conveying pipe, the chocolate slurry is not only in a uniform progressive state when it flows macroscopically in the first crystal tube, the second crystal tube and the third crystal tube, but can also be in a progressive and uniform heating mode when it flows in a single conveying pipe, which is conducive to further ensuring the uniform stability of the chocolate slurry during the temperature control process; 3. In the present invention, by arranging the connecting pipe between the electric three-way valve and the water outlet pipe, the water flow returning from the return pipe can be directly introduced into the water outlet pipe and pumped back into the output pipe by the water pump, which can effectively increase the initial temperature of the water flow pumped by the water pump, and is conducive to reducing the energy loss of the water flow being heated to the preset temperature during the circulation process, thereby being conducive to achieving the purpose of saving resources and achieving the effect of energy saving, emission reduction and green production; 4.

In the present invention, by sequentially connecting the first circulation pipe, the second circulation pipe and the third circulation pipe between the discharge port of the third crystallization tube and the feed ports of the third crystallization tube, the second crystallization tube and the first crystallization tube, and cooperating with the monitoring of the temperature sensor arranged at the discharge port of the third crystallization tube, the chocolate slurry that does not meet the requirements can be refluxed to the feed ports of the first crystallization tube, the second crystallization tube and the third crystallization tube, and the circulation route of the chocolate slurry is optimized according to the actual situation, so that the heat loss in the low temperature area during the reflux process of the chocolate slurry with a higher temperature can be avoided, which is beneficial to improving the efficiency of the chocolate slurry circulation temperature rise control, and to a certain extent reduces the energy loss, which is beneficial to achieve energy-saving production; 6. In the present invention, by evenly arranging the strip-shaped air bags on the inner end walls of the first circulation pipe, the second circulation pipe and the third circulation pipe, and cooperating with the inflation of the air pump, when the first circulation pipe, the second circulation pipe and the third circulation pipe are not used as circulation routes, the strip-shaped air bags are inflated and filled in the first circulation pipe, the second circulation pipe and the third circulation pipe, which can not only seal them but also push the chocolate slurry out, which is beneficial to avoid a large amount of chocolate slurry remaining in the first circulation pipe, the second circulation pipe and the third circulation pipe, and to a certain extent ensures the stability of the device when it is actually used.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a new type of chocolate tempering machine, see Figure 1 - Fig.14 Specifically, it includes a machine body 1, in which an electric control box 101 and a heat preservation cylinder 102 are fixedly installed, and a slurry pump 103 is fixedly connected to the bottom of the heat preservation cylinder 102, a slurry outlet pipe 104 is fixedly installed on the machine body 1, and a temperature sensor is installed in the slurry outlet pipe 104, and a first crystallization tube 107, a second crystallization tube 108 and a third crystallization tube 109 arranged side by side in the machine body 1 are sequentially connected in series between the slurry pump 103 and the slurry outlet pipe 104, and the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109 all include a vertically arranged conveying pipe 2, and a temperature regulating chamber 201 is sleeved on the outer side of the conveying pipe 2, and water inlet joints 202 are respectively fixed at the upper and lower ends of the temperature regulating chamber 201 and a water outlet joint 203, a first water tank 3, a second water tank 301 and a third water tank 302 corresponding to the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109 are fixedly installed in the machine body 1, the first water tank 3, the second water tank 301 and the third water tank 302 all include a box body 4, and the bottom of the box body 4 is fixedly connected with a water outlet pipe 401, the top of the box body 4 is fixedly connected with a return pipe 402, an output pipe 303 is connected between the water outlet pipe 401 and the corresponding water inlet joint 202, a return pipe 304 is connected between the return pipe 402 and the corresponding water outlet joint 203, and a water pump 305 and an electric heating module 306 are installed on each output pipe 303.

[0021] When the device is used, the staff connects the device to an external power supply so that the external power supply provides power support for the device. Then, the staff can control the device to be powered on and started. The chocolate slurry is pre-stored in the heat preservation cylinder 102. After the slurry pump 103 is powered on and started, the slurry in the heat preservation cylinder 102 can be pumped. The chocolate slurry passes through the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109, which are connected in series with the conveying pipe 2, and is finally output to the outside through the slurry outlet pipe 104. Synchronously, the first water tank 3, the second water tank 301 and the third water tank 302 are connected to the conveying pipe 2 in series. The water pump 305 and the electric heating module 306 corresponding to the box 302 are powered on and started. After the water pump 305 is powered on and started, the water stored in the box 4 can be circulated and pumped. With the connection between the output pipe 303 and the return pipe 304, the water circulates in the box 4 and the corresponding temperature adjustment chamber 201. When the water flows through the output pipe 303, it will be heated by the electric heating module 306 fixed on the output pipe 303, so that the water temperatures delivered to the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109 in the corresponding temperature adjustment chamber 201 are different. The temperatures of the water flows in the temperature regulating chamber 201 corresponding to the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109 can be independently controlled. When the chocolate slurry passes through the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109, it can be heated to a preset temperature by the water flows in the corresponding temperature regulating chamber 201. The water flow temperatures in the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109 are progressively set, so that the chocolate slurry can be tempered in three stages and the chocolate slurry can be heated to a preset temperature by the water flows in the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109. The temperature adjustment process of the chocolate slurry is gradual, which is conducive to avoiding the sudden change of temperature during the temperature adjustment process of the chocolate slurry and affecting its quality, and to a certain extent improves the temperature adjustment effect during the transportation of the chocolate slurry. Since the temperature adjustment chamber 201 is wrapped around the outside of the transportation pipe 2, the chocolate slurry is heated and temperature-controlled by water bath heating when moving in the transportation pipe 2. Compared with the temperature adjustment method of direct heating with electric heating wire in the prior art, the temperature control stability and uniformity of the temperature adjustment area can be effectively guaranteed, thereby making the temperature adjustment of the chocolate slurry more stable and uniform.

[0022] In the specific implementation process, Figure 2 and Figure 4As shown, the slurry discharge pipe 104 is fixedly connected with an inspection circulation pipe 105 arranged just above the heat preservation cylinder 102, and butterfly valves 106 are fixedly installed in the inspection circulation pipe 105 and at the ends of the slurry discharge pipe 104. When the device is used, the staff can open the butterfly valve 106 on the inspection circulation pipe 105, so that the chocolate slurry after temperature adjustment is discharged through the inspection circulation pipe 105. At this time, the staff can observe the state of the chocolate slurry discharged from the inspection circulation pipe 105, so as to judge the temperature adjustment of the chocolate slurry. The inspection circulation pipe 105 is arranged just above the heat preservation cylinder 102. When the chocolate slurry is discharged outward through the inspection circulation pipe 105 for the staff to During observation and inspection, the staff can open the top of the insulation cylinder 102 in advance, so that the chocolate slurry discharged from the inspection circulation pipe 105 falls directly into the insulation cylinder 102, which can not only avoid the pollution caused by the arbitrary flow of chocolate slurry during observation and inspection, but also avoid the waste of chocolate slurry. In addition, the device can also monitor the temperature of the chocolate slurry in the slurry outlet pipe 104 through the temperature sensor. During the initial startup, if the temperature of the chocolate slurry discharged from the slurry outlet pipe 104 does not meet the requirements, it can be directly discharged into the insulation cylinder 102 through the inspection circulation pipe 105 for circulating temperature adjustment until the temperature of the chocolate slurry reaches the required requirements and is then discharged through the slurry outlet pipe 104.

[0023] In the specific implementation process, Figure 6 , Figure 7 and Fig. 9 As shown, a guide plate 204 arranged between a water inlet joint 202 and a water outlet joint 203 is fixedly installed in the temperature regulating chamber 201, and the guide plate 204 is arranged in a spiral structure, the lower end of the first crystallization tube 107 is connected to the slurry pump 103, the upper end of the first crystallization tube 107 is connected to the upper end of the second crystallization tube 108, the lower end of the second crystallization tube 108 is connected to the lower end of the third crystallization tube 109, and the upper end of the third crystallization tube 109 is connected to the slurry outlet pipe 104, the water inlet joint 202 on the temperature regulating chamber 201 in the first crystallization tube 107 and the third crystallization tube 109 is arranged at the top, and the water outlet joint 203 is arranged at the top. The water inlet joint 202 on the temperature regulating chamber 201 in the second crystallization tube 108 is arranged at the bottom, and the water outlet joint 203 is arranged at the top. The water flow direction in the temperature regulating chamber 201 is opposite to the flow direction of the slurry in the conveying pipe 2. When the device is used, since the guide plate 204 with a spiral structure is fixedly installed in the temperature regulating chamber 201, the water flow circulating in the temperature regulating chamber 201 can be guided, so that the temperature regulating water flow flows in the temperature regulating chamber 201 in a unidirectional and orderly spiral shape, which is beneficial to further improve the uniformity of the temperature regulating water flow in the temperature regulating chamber 201 on the temperature regulating heating of the chocolate slurry in the conveying pipe 2.

[0024] In the device, since the conveying pipes 2 in the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109 are arranged in series with each other, the chocolate slurry moves from bottom to top in the conveying pipe 2 in the first crystal tube 107, moves from top to bottom in the conveying pipe 2 in the second crystal tube 108, and moves from bottom to top in the conveying pipe 2 in the third crystal tube 109. Correspondingly, the temperature-adjusting water flow in the temperature-adjusting chamber 201 in the first crystal tube 107 and the third crystal tube 109 moves from top to bottom, and the temperature-adjusting water flow in the temperature-adjusting chamber 201 in the second crystal tube 108 moves from bottom to top, so that the corresponding moving directions of the temperature-adjusting water flow in the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109 are all aligned with the chocolate slurry. The moving direction of the temperature-adjusting water flow is opposite to that of the chocolate slurry. The temperature-adjusting water flow enters the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109 from the outlet end of the chocolate slurry, and then exits from the inlet end of the chocolate slurry. Considering the heat consumption of the temperature-adjusting water flow during the temperature-adjusting process of the chocolate slurry when the temperature-adjusting water flow moves, the temperature of the water flow when it initially enters is higher than the temperature of the water flow when it exits, and the temperature decreases evenly and slowly due to the heat consumption during the water flow entering and exiting. This allows the chocolate slurry to be temperature-adjusted in a uniform and progressive state not only during macroscopic flow in the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109, but also during flow in a single conveying tube 2. It can still be heated in a progressive and uniform manner, which is beneficial to further ensure the uniform stability of the chocolate slurry during the temperature-adjusting process.

[0025] In the specific implementation process, Figure 6 , Figure 7 , Fig.12 and Fig.14 As shown, a temperature sensor is also installed in the return pipe 304, an electric three-way valve 403 is fixedly connected between the return pipe 402 and the corresponding return pipe 304, and a connecting pipe 404 is fixedly connected between the other end of the electric three-way valve 403 and the outlet pipe 401, and a plurality of through grooves 405 staggered left and right are sequentially opened in the upper half of the box body 4 from top to bottom, and an S-shaped flow channel 406 connected to the return pipe 402 is formed inside the upper half of the box body 4 due to the numerous through grooves 405, and a plurality of evenly distributed metal sheets 407 are fixedly installed in the through grooves 405.

[0026] During the use of the device, when the first water tank 3, the second water tank 301 and the third water tank 302 are used to control the temperature of the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109, since the temperature of the water flowing back from the return pipe 304 to the box body 4 is significantly higher than the original water flow temperature stored in the box body 4, the device does not need to introduce the water flowing back in the return pipe 304 into the box body 4. With the control of the electric three-way valve 403 and the connection with the connecting pipe 404, the device can directly introduce the water flowing back in the return pipe 304 into the water outlet pipe 401, and the water pump 305 re-pumps it back into the output pipe 303, so that the temperature of the water flowing back in the return pipe 304 will not be reduced due to the combination with the original water flow in the box body 4, and the initial temperature of the water pumped by the water pump 305 can be effectively increased, which is beneficial to reducing the energy loss of being heated to the preset temperature during the circulation of the water flow, thereby facilitating the purpose of saving resources and achieving the effect of energy saving, emission reduction and green production.

[0027] When performing temperature control, if it is necessary to lower the temperature of the water flow in the temperature control chamber 201, after the staff lowers the heating temperature of the electric heating module 306, the temperature sensor will monitor the temperature of the return water flow in the return pipe 304. If the temperature of the return water flow in the return pipe 304 is less than or equal to the temperature after the temperature reduction adjustment of the corresponding electric heating module 306, the electric three-way valve 403 still keeps the return pipe 304 and the connecting pipe 404 in a conductive state. If the temperature of the return water flow in the return pipe 304 is greater than the temperature after the temperature reduction adjustment of the corresponding electric heating module 306, the electric three-way valve 403 keeps the return pipe 304 and the return water pipe 402 in a conductive state. The water flow returning from the box 404 is no longer directly transported to the outlet pipe 401 through the connecting pipe 404, but returns to the upper part of the box 4 through the return pipe 402. The high-temperature returning water flow enters the S-shaped flow channel 406 from the return pipe 402, and the heat exchange area is increased by the through groove 405 and the metal sheet 407 to quickly dissipate heat and cool down, thereby reducing the temperature of the water flow returning to the box 4. The above-mentioned structural arrangement enables the device to not only efficiently and stably perform upward temperature control when performing temperature control, but also efficiently and stably perform downward temperature control, which to a certain extent improves the control efficiency of the device for positive and negative temperature control of chocolate slurry.

[0028] In the specific implementation process, Fig. 9 and Fig.13As shown, a vertically arranged spiral roller 5 is rotatably installed in each conveying pipe 2, a motor 6 is fixedly installed in the machine body 1, a first roller 601 is fixedly installed on the driving shaft of the motor 6, a second roller 602 arranged below the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109 is fixedly installed at the bottom end of each spiral roller 5, a transmission belt 603 is commonly connected between the first roller 601 and the three second rollers 602, a base 604 is provided between each adjacent second roller 602, and a slide 605 is slidably installed on the top of the base 604, an elastic element 606 for elastically supporting the slide 605 is fixedly installed on the base 604, and a tensioning wheel 607 for tensioning the transmission belt 603 is rotatably installed on the top of the slide 605.

[0029] When the device is in use, under the elastic support of the elastic element 606, the tensioning wheel 607 can squeeze the transmission belt 603, so that the transmission belt 603 is tensioned between the first roller 601 and the three second rollers 602. When the motor 6 is powered on and started, the first roller 601 and the second roller 602 cooperate with the transmission connection of the transmission belt 603 to drive the spiral rollers 5 rotatably installed in the three conveying pipes 2 to rotate synchronously. With the help of the axial conveying force generated during the rotation of the spiral rollers 5, the chocolate slurry can be assisted to move more smoothly and stably in the conveying pipe 2. At the same time, with the help of the stirring and mixing generated during the rotation of the spiral rollers 5, the chocolate slurry can be dispersed more evenly when moving in the conveying pipe 2, which is beneficial to further improve the heating uniformity of the chocolate passing through the conveying pipe 2 when being tempered.

[0030] In the specific implementation process, Figure 6 As shown, a temperature sensor is also installed at the discharge port of the third crystallization tube 109, a first circulation pipe 7 is fixedly connected between the discharge port of the third crystallization tube 109 and the feed port of the third crystallization tube 109, a second circulation pipe 701 is fixedly connected between the discharge port of the third crystallization tube 109 and the feed port of the second crystallization tube 108, a third circulation pipe 702 is fixedly connected between the discharge port of the third crystallization tube 109 and the feed port of the first crystallization tube 107, and electric control valves 703 are fixedly installed at the ends of both sides of the first circulation pipe 7, the second circulation pipe 701 and the third circulation pipe 702.

[0031] During the initial startup, there may be a large gap between the initial temperature of the chocolate slurry in the heat preservation cylinder 102 and the preset temperatures of the first crystallization tube 107, the second crystallization tube 108, and the third crystallization tube 109. This makes it difficult for the chocolate slurry to be quickly heated to the preset temperature when passing through the first crystallization tube 107, the second crystallization tube 108, and the third crystallization tube 109 for a single time. In order to ensure that the chocolate slurry can stably reach the preset temperature, the chocolate slurry needs to be circulated and heated. After the chocolate slurry passes through the first crystallization tube 107, the second crystallization tube 108, and the third crystallization tube 109 in turn for temperature adjustment, the temperature sensor installed at the outlet of the third crystallization tube 109 detects the temperature of the chocolate slurry and selects a suitable reflux route according to the temperature of the chocolate slurry at the outlet of the third crystallization tube 109.

[0032] When the temperature of the chocolate slurry at the outlet of the third crystallization tube 109 is lower than the temperature of the temperature-adjusting water flow in the temperature-adjusting chamber 201 of the first crystallization tube 107, the electric control valves 703 at both ends of the third circulation tube 702 are controlled to open, and the third circulation tube 702 is enabled as a circulation route to return the chocolate slurry to the feed inlet of the first crystallization tube 107. When the temperature of the chocolate slurry at the outlet of the third crystallization tube 109 is higher than the temperature of the temperature-adjusting water flow in the temperature-adjusting chamber 201 of the first crystallization tube 107, but lower than the temperature of the temperature-adjusting water flow in the temperature-adjusting chamber 201 of the second crystallization tube 108, the electric control valves 703 at both ends of the second circulation tube 701 are controlled to open, and the second circulation tube 701 is enabled as a circulation route to return the chocolate slurry to the feed inlet of the second crystallization tube 108. When the temperature of the chocolate slurry at the outlet of the third crystallization tube 109 is lower than the temperature of the temperature-adjusting water flow in the temperature-adjusting chamber 201 of the third crystallization tube 109, the electric control valves 703 at both ends of the second circulation tube 701 are controlled to open, and the second circulation tube 701 is enabled as a circulation route to return the chocolate slurry to the feed inlet of the second crystallization tube 108. When the temperature of the temperature-adjusting water flow in the temperature-adjusting chamber 201 is higher than the temperature of the temperature-adjusting water flow in the temperature-adjusting chamber 201 in the second crystallization tube 108, the electric control valves 703 at both ends of the first circulation tube 7 are controlled to open, and the first circulation tube 7 is enabled as a circulation route to return the chocolate slurry to the feeding port of the third crystallization tube 109. Pumps can be installed in the first circulation tube 7, the second circulation tube 701 and the third circulation tube 702 to assist the smooth return of the chocolate slurry. A suitable circulation route is selected according to the actual temperature of the chocolate slurry at the discharge port of the third crystallization tube 109. Compared with returning the chocolate slurry directly to the heat preservation cylinder 102, heat loss in the low temperature area during the return of the chocolate slurry with a higher temperature can be avoided, which is beneficial to improving the efficiency of the chocolate slurry circulation temperature rise regulation and control, and to a certain extent reduces the energy loss, which is beneficial to achieving energy-saving production.

[0033] In the specific implementation process, Fig.10As shown, the inner end walls of the first circulation pipe 7, the second circulation pipe 701 and the third circulation pipe 702 are all installed with uniformly distributed strip air bags 8, and an air pump is fixedly installed in the body 1, and the strip air bags 8 are connected to the air pump. During the use of the device, when the first circulation pipe 7, the second circulation pipe 701 and the third circulation pipe 702 are not used as circulation routes, the air pump is powered on to blow the strip air bags 8 connected thereto, and the strip air bags 8 are filled in the first circulation pipe 7, the second circulation pipe 701 and the third circulation pipe 702 through inflation, which can not only block them, but also The chocolate slurry is pushed outward to prevent a large amount of chocolate slurry from remaining in the first circulation tube 7, the second circulation tube 701 and the third circulation tube 702. When the strip air bag 8 is inflated by the air pump, the air inlet of the air flow is close to the outlet position of the third crystallization tube 109. This allows the strip air bag 8 to be gradually inflated and expanded, and the chocolate slurry remaining in the first circulation tube 7, the second circulation tube 701 and the third circulation tube 702 can be pushed to the inlet position of the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109, which is conducive to ensuring the stability of the device during actual use.

[0034] Specifically, the working principle and operation method of the present invention are as follows: The chocolate slurry is stored in the heat preservation cylinder 102. The slurry pump 103 pumps the chocolate slurry and cooperates with the motor 6 to drive the spiral roller 5 to rotate, thereby generating an axial conveying force in the conveying pipe 2, so that the chocolate slurry passes through the conveying pipe 2 in the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109 in turn, and is finally discharged outward through the slurry outlet pipe 104. In this process, the water pumps 305 corresponding to the first water tank 3, the second water tank 301 and the third water tank 302 circulate water into the first crystallization tube 107, In the temperature regulating chamber 201 in the second crystal tube 108 and the third crystal tube 109, the electric heating modules 306 are used to heat and control the temperature of the temperature regulating water flow in the three temperature regulating chambers 201. By means of water bath heating, the chocolate slurry flowing through the conveying pipe 2 is temperature regulated. The temperature of the temperature regulating water flow in the temperature regulating chamber 201 in the first crystal tube 107, the second crystal tube 108 and the third crystal tube 109 is set progressively, and the flow direction of the water flow in the temperature regulating chamber 201 corresponds to the chocolate slurry in the corresponding conveying pipe 2. The moving directions are opposite, so that the temperature of the chocolate slurry is gradually and evenly regulated. The chocolate slurry that meets the requirements is discharged outward through the slurry discharge pipe 104. When the temperature control is performed, the water flow in the reflux pipe 304 can not only flow back directly into the box body 4, but also be directly introduced into the water outlet pipe 401 through the control of the electric three-way valve 403 and the connection of the connecting pipe 404, so as to improve the initial temperature of the temperature-adjusting water flow when it circulates and refluxes, which is beneficial to reduce energy consumption. During the temperature adjustment process of the chocolate slurry, the temperature of the chocolate slurry discharged from the discharge port of the third crystallization tube 109 will be detected. According to the actual temperature of the chocolate slurry at the discharge port of the third crystallization tube 109, a suitable circulation route is selected, and the chocolate slurry that does not meet the requirements is returned to the feed ports of the first crystallization tube 107, the second crystallization tube 108 and the third crystallization tube 109 through the first circulation pipe 7, the second circulation pipe 701 and the third circulation pipe 702 respectively. The chocolate slurry circulation route is optimized according to the actual situation, which can improve the temperature adjustment efficiency and reduce energy consumption.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
