Description

Technical Field

[0001] The invention belongs to the technical field of beverage refining equipment, and in particular relates to a canned fruit production device. Background Art

[0002] The processing of canned fruit is a food processing process in which fresh fruits are processed, canned, sealed, sterilized, and can be preserved for a long time at room temperature. After the pulp is added to the canning bottle, concentrated juice will be added to keep the pulp in a soaked state to ensure the taste of the pulp in the can.

[0003] The juice added to the canned food cannot be juice puree, because the puree contains more colloid and other solid substances. Directly adding it to the inside of the can will cause the liquid to be unclear or produce precipitation, and it will affect the appearance when packaged in transparent canning bottles. Therefore, it is necessary to refine the juice puree to remove unwanted substances. The conventional juice puree purification process is distillation. However, if deep distillation is performed at high temperature, the colloid in the juice puree will overheat and coke, which will affect the taste. If a low degree of distillation is used, that is, the distillation is stopped when the juice puree has reached half of its original volume, the utilization rate of the puree will be low and the cost of extracting concentrated juice will be high. In view of this, a fruit canned food production device is provided. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a canned fruit production device.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A canned fruit production device comprises a frame and also comprises:

[0007] A clarification and concentration tank fixed in the frame, the clarification and concentration tank comprising a main tank which is vertically arranged and can be driven to rotate, a heater is provided at the lower part of the outer side of the main tank, fins are provided along the radial direction of the inner wall of the main tank, a stirrer which can rotate independently is provided in the middle of the main tank, and the heater is arranged around the bottom opening of the main tank to form a sedimentation chamber;

[0008] A liquid pipe group for providing liquid juice puree to the main tank;

[0009] A gas pipe assembly for leading gas out of the main tank, wherein the gas pipe assembly can provide a vacuum environment for the main tank;

[0010] A metering reversing valve for connecting a liquid pipe group and a gas pipe group;

[0011] A pipeline connector for controlling the on-off of a metering reversing valve and a quick plug, the pipeline connector comprising a main body, an input channel connected to the metering reversing valve, and an output channel arranged inside the main body, a second solenoid valve is arranged between the input channel and the output channel, a cover plate with a quick plug is arranged on the top of the main tank, the main body is located directly above the quick plug and is retractable and provided with a plug sleeve, and the plug sleeve can open the quick plug in a normally closed state when it is moved downward;

[0012] A waste pipe group is connected to the sedimentation chamber.

[0013] During operation, the liquid pipe group introduces the liquid juice puree into the main tank. The metering reversing valve is opened to allow the liquid juice puree to pass through the pipe connector. The solenoid valve 2 of the pipe connector is opened to allow the plug-in sleeve to move downward and connect with the quick plug. After a certain amount of liquid juice puree enters the main tank, the plug-in sleeve moves upward and separates from the quick plug. At the same time, the quick plug closes the main tank. The main tank rotates at high speed for centrifugal clarification. The heater provides temperature to heat the liquid juice puree and make it easier to flow. The fins increase the contact area with the liquid juice puree so that the liquid juice puree is quickly driven to a high-speed rotation state. After multiple rotations, the separated solid impurities will enter the sedimentation chamber due to gravity and be discharged uniformly by the parallel waste pipe group, while the remaining juice puree clear liquid is continued to be discharged by the heater. Heating is performed for distillation. To avoid high temperature from destroying the flavor of the juice puree, the gas pipe group evacuates the inside of the main tank through the pipe connector before heating, and then distills in a vacuum state, which can reduce the temperature required for distillation. The clarified juice puree has less colloid inside, and flows smoothly and heats up quickly under the promotion of the agitator. It can also avoid the high-temperature coking of the colloid that affects the taste. The juice vapor after distillation is drawn out, cooled and collected uniformly to obtain concentrated juice, so as to add it to cans to enrich the taste of the product. When the remaining juice puree in the main tank reaches one-quarter of its volume, the heating is stopped, and the inner wall of the main tank is self-cleaned by rotating the main tank and the agitator in the opposite direction. Finally, the residual liquid is discharged through the waste pipe group and waits for the next clarification and concentration work.

[0014] Furthermore, the quick plug includes a central tube, which is arranged through the edge of the cover plate, the aperture of the upper half of the opening of the central tube is reduced, and a sealing plug is provided at the lower half of the opening of the central tube. The sealing plug is always pressed against the top opening position of the opening of the central tube through an elastic member, and a pin rod with an outer diameter smaller than the inner diameter of the opening of the central tube is provided in the middle of the plug-in sleeve.

[0015] Through the above technical solution, the opening of the quick plug is narrow at the top and wide at the bottom, and the sealing plug is pushed into the narrow section of the opening from bottom to top under the action of the elastic member to achieve sealing. When the plug-in sleeve is arranged on the outer side of the middle tube and moves downward, the pin rod is inserted into the opening to press the sealing plug downward to separate from the narrow section of the opening, so that the connection between the middle tube and the plug-in sleeve can be completed. When the pin rod and the plug-in sleeve move upward and separate, the elastic member again pushes the sealing plug into the narrow section of the opening to complete the closure.

[0016] Furthermore, the main body has a built-in detection channel, which is connected to the metering reversing valve. The main body is provided with a pressure sensor at the detection channel port. The main body is provided with a control channel at the corresponding plug-in sleeve. The control channel is connected to an air supply device through an electromagnetic valve. The increase in air pressure inside the control channel can push the plug-in sleeve downward.

[0017] Through the above technical scheme, when the metering reversing valve provides liquid juice puree to the main tank or extracts the air in the main tank, the pressure in the detection channel will change significantly. At this time, the pressure sensor detects the pressure change and can provide a feedback signal for the downward movement of the plug-in sleeve. After receiving the signal, the gas supply equipment provides high-pressure gas to the control channel through the solenoid valve 1, and drives the plug-in sleeve to move downward. The structure is compact and the driving efficiency is high.

[0018] Furthermore, the control channel is provided with a cylindrical cavity with a vertical axis, the plug-in sleeve is vertically movably arranged in the cylindrical cavity, an annular flange is provided in the middle of the circumferential outer wall of the plug-in sleeve, and a telescopic part is provided below the annular flange.

[0019] Through the above technical solution, in order to ensure the normal resetting of the plug-in sleeve, the annular flange compresses the telescopic part when the plug-in sleeve moves downward, and when the air supply equipment stops working, the telescopic part squeezes the annular flange to make the plug-in sleeve move upward, thereby realizing autonomous resetting.

[0020] Furthermore, the control channel is provided with a cylindrical cavity with a vertical axis, the plug-in sleeve is vertically movably arranged in the cylindrical cavity, an annular flange is provided in the middle of the circumferential outer wall of the plug-in sleeve, the vertical outer wall of the annular flange is in sliding contact with the vertical inner wall of the cylindrical cavity, and a sealing cavity is formed between the lower surface of the annular flange and the inner wall of the bottom end of the cylindrical cavity.

[0021] Through the above technical solution, a certain amount of gas is sealed in the sealing cavity. When the plug-in sleeve moves downward, the annular flange compresses the gas. Similarly, when the gas supply equipment stops working, the gas rebounds and squeezes the annular flange to make the plug-in sleeve move upward, thereby achieving self-reset. There is no need to design a telescopic part, which further reduces the number of parts and avoids the problem of poor reset caused by elastic fatigue of the telescopic part.

[0022] Furthermore, the clarification and concentration tank also includes a box body, the main tank and the heater are sealed and wrapped by the box body, and the middle section of the liquid pipe group is located in the box body.

[0023] Through the above technical solution, the box body has a hollow structure, which can protect the main tank and the heater, and can also lock the heat dissipated from the main tank and the heater, heat the middle section of the liquid pipe group, so that the internal liquid juice puree is preheated by the overflow heat before entering the main tank, thereby improving the utilization rate of the heater's heat, reducing the heating time of the liquid juice puree, and improving the clarification efficiency of the liquid juice puree.

[0024] Furthermore, a rotating driving member is provided on the side wall of the box body, and the rotating driving member is used to drive the main tank to rotate. A limiting frame is installed on the inner wall of the box body opposite to the rotating driving member.

[0025] Through the above technical solution, the rotating drive member is driven by a servo motor, which can control the rotation accuracy and ensure that the quick plug can be smoothly aligned with the plug sleeve when connecting the pipe. Ordinary motors can also be used with position sensors to achieve the positioning function. The rotating drive member squeezes the main tank to increase friction for power transmission. The limit frame squeezes from the opposite side to ensure that the axis of the main tank is vertical, avoiding large vibrations when the main tank rotates at high speed.

[0026] Furthermore, the lowest points of the fins and the agitator are located above the sedimentation chamber, the box body is formed with an inclined guide surface at the bottom end of the heater, the lowest point of the inclined guide surface is located at the entrance of the waste pipe group, and the heater is provided with a notch at the lowest point of the inclined guide surface.

[0027] Through the above technical solution, after clarification, the generated solid impurities enter the sedimentation chamber, and smoothly enter the waste discharge pipe group under the guidance of the inclined guide surface. The lowest point of the fin is located above the sedimentation chamber. During the centrifugation process, the solid impurities separated under the action of gravity will continue to fall. Once they leave the fins and enter the sedimentation chamber, they will not continue to rotate rapidly, which can avoid the separated solid impurities from being excessively disturbed, shorten the separation time, and further improve the clarification efficiency.

[0028] Furthermore, a hollow interlayer is provided between the inner wall of the heater and the outer wall of the main tank, a heating coil is coiled in the hollow interlayer, the lower half of the heating coil is fixedly connected to the heater, and an anti-wear sleeve is provided between the upper half of the heating coil and the outer wall of the main tank.

[0029] Through the above technical scheme, when heating, a heating coil that is powered on to heat up is used to quickly heat up the required temperature environment, thereby improving the heating efficiency. The heating coil directly transfers the heat to the heater, and then heats the juice puree liquid in the lower layer of the main tank, thereby preventing the relatively turbid juice puree liquid in the lower layer from quickly heating up and causing coking. The upper half of the heating coil is in direct contact with the outer wall of the main tank, and quickly conducts heat to heat the relatively clear juice puree liquid in the middle and upper layers, so that the clear juice puree liquid in the upper layer can continue to boil and volatilize, thereby improving the distillation efficiency.

[0030] Furthermore, a hollow interlayer is provided between the inner wall of the heater and the outer wall of the main tank, a heat exchange medium is contained in the hollow interlayer, and delivery pipes are provided at both ends of the top and bottom of the hollow interlayer of the heater.

[0031] Through the above technical scheme, the heat transfer medium carrying heat is continuously passed through the hollow interlayer to heat the main tank, which can improve the uniformity of heating and ensure the slow increase of heating temperature. It can adapt to the heating scenarios of juice puree with high gelatin and fruit protein such as apple juice, cherry juice, kiwi juice, etc.

[0032] The beneficial effects of the present invention are as follows:

[0033] (1) The present invention can separate as much solid colloid that is easily coked by heat as possible from the juice puree by optimizing the clarification and concentration tank and centrifuging the main tank. Before heating, the gas pipe group evacuates the interior of the main tank, and distillation is performed in a vacuum state to reduce the required temperature. The colloid that is evaporated by heating can fall into the precipitation chamber and escape from the heating range of the fins, thereby avoiding accumulation at the bottom of the fins to affect heat transfer or cause coking and adhesion.

[0034] (2) The present invention arranges fins and a stirrer. During centrifugation, the main tank and the stirrer rotate synchronously at high speed. The fins and the stirrer increase the contact area with the liquid juice puree, so that the liquid juice puree is quickly driven to a high-speed rotation state. During distillation, the fins efficiently heat the juice clear liquid close to the inner wall of the main tank, and the stirrer turns the juice clear liquid away from the inner wall of the main tank close to the main tank, thereby improving the uniformity of heating of the material.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] like Figure 1 - Fig.11 As shown, this embodiment provides a canned fruit production device, including a frame 1, and also includes:

[0049] For the clarification and concentration tank 5, refer to Figure 3 , Figure 4 and Fig. 9The clarification and concentration tank 5 is fixed in the frame 1, wherein the clarification and concentration tank 5 includes a vertically arranged main tank 51 which can be driven to rotate. The main tank 51 rotates to centrifugally clarify the liquid juice inside. At the same time, a heater 52 is provided at the lower outer part of the main tank 51, which can directly heat and distill the clarified liquid juice without transfer and transportation. It should be noted that fins 511 are provided on the inner wall of the main tank 51 in the radial direction, and a stirrer 54 which can rotate independently is provided in the middle of the main tank 51. During centrifugation, the stirrer 54 and the main tank 51 rotate synchronously as a whole, and the fins 511 can drive the liquid juice to quickly follow the main tank 51 to rotate at a high speed. During distillation, the fins 511 can increase the heating area of ​​the liquid juice, and the stirrer 54 can be reversed to make the liquid juice away from the fins 511 flip close to the fins 511 for uniform temperature increase. In addition, referring to Fig. 9 and Fig.10 The heater 52 is surrounded by a sedimentation chamber 59 at the bottom opening of the main tank 51. Solid impurities generated by centrifugation will enter the sedimentation chamber 59 under the action of gravity and be discharged uniformly. During distillation, solids such as pectin that are re-precipitated as the liquid juice decreases can also fall into the sedimentation chamber 59 and escape from the heating range of the fins 511, avoiding accumulation at the bottom of the fins 511 to affect heat transfer or cause coking and adhesion.

[0050] For liquid pipe group 2, refer to Fig.11 A two-way metering pump is installed at the end of the liquid pipe group 2, and an electromagnetic three-way reversing valve is provided at the inlet end of the pumping device, which can be connected to the juice puree storage tank and the cleaning water storage tank respectively. The liquid pipe group 2 provides the main tank 51 with liquid juice puree to be refined, and can also provide cleaning water;

[0051] For gas pipe set 6, refer to Fig.11 A two-way metering pump is installed at the end of the gas pipe group 6. Before distillation, the gas pipe group 6 leads the gas out of the main tank 51 to provide a vacuum environment for the main tank 51. During distillation, the gas pipe group 6 can continuously introduce juice vapor into the juice vapor condenser to maintain the vacuum environment while recovering and cooling the finished product for subsequent preparation of concentrated juice;

[0052] Metering reversing valve 8, see Figure 3 The metering reversing valve 8 is used to connect the liquid pipe group 2 and the gas pipe group 6. In the stage of providing liquid juice puree, the metering reversing valve 8 connects the liquid pipe group 2 with the main tank 51. In the distillation stage, the metering reversing valve 8 connects the gas pipe group 6 with the main tank 51, which plays the role of pipeline conversion and flow detection.

[0053] For pipe connector 3, refer to Figure 3 , Figure 5 and Figure 6The pipeline connector 3 is used to control the on-off of the metering reversing valve 8 and the quick plug 58. The pipeline connector 3 includes a main body 31, which is a metal casting with high strength. An input channel 37 and an output channel 39 connected to the metering reversing valve 8 are provided in the main body 31. At the same time, a solenoid valve 38 is provided between the input channel 37 and the output channel 39. Figure 5 , and a cover plate 53 with a quick plug 58 is provided on the top of the main tank 51, referring to Figure 6 The main body 31 is located directly above the quick plug 58 and is retractably provided with a plug sleeve 36. When the metering reversing valve 8 and the quick plug 58 need to be connected, refer to Figure 7 , the plug sleeve 36 can open the fast plug 58 in the normally closed state when it is inserted downward. When the metering reversing valve 8 and the fast plug 58 need to be disconnected, refer to Figure 8 , the plug sleeve 36 can be disengaged from the quick plug 58 when it moves upward, and the quick plug 58 automatically resets and closes;

[0054] For exhaust pipe group 7, refer to Fig.10 The waste pipe group 7 is connected to the sedimentation chamber 59 to lead out the solid impurities produced by centrifugal clarification, so that the main juice puree clear liquid in the main tank 51 can be discharged after distillation, or the cleaning liquid can be discharged after introducing clean water for cleaning, so as to facilitate the cleaning of the internal space of the main tank 51.

[0055] The practical problem solved by this solution is how to extract as much concentrated juice as possible while avoiding overheating and coking of the juice. First, through the centrifugal action of the main tank 51, as much solid colloid that is easily coked by heat can be separated from the juice puree as much as possible. Secondly, before heating, the gas pipe group 6 evacuates the inside of the main tank 51, and the distillation is carried out in a vacuum state to reduce the required temperature. Finally, as the colloid evaporates during heating, it can fall into the precipitation chamber 59 and leave the heating range of the fin 511, avoiding accumulation at the bottom of the fin 511 to affect heat transfer or cause coking and adhesion. In addition, driven by the agitator 54, the centrifugal efficiency is higher, the distillation rate is faster, and the inner wall of the main tank 51 can be self-cleaned.

[0056] In a further embodiment, a specific configuration of the main tank 51 is provided, referring to Fig. 9 and Fig.10The main tank 51 adopts a stepped inner diameter design, with a large inner diameter at the top, a smaller inner diameter in the middle, and a smallest inner diameter at the bottom. During centrifugation, solid matter will settle downward, resulting in an increase in the concentration of the juice puree as the depth increases. This shape of the main tank 51 can increase the rotational angular velocity of the materials in the middle and lower layers, thereby improving the centrifugal efficiency. The fins 511 are also designed to be narrow at the top and wide at the bottom, so that they can be inserted deeper into the juice puree in the lower layer, driving the viscous juice puree in the lower layer to rotate synchronously with the main tank 51 at a high speed, thereby achieving the purpose of targeted centrifugation and ensuring the effect of centrifugation. Similarly, during distillation, the cavity volume of the lower part of the main tank 51 is reduced due to the reduction in radius, and the distance from the material with a higher concentration at the center of the lower layer to the side wall of the main tank 51 is smaller, which can improve the heating effect of the material with a higher concentration in the lower layer and ensure uniform and rapid heating.

[0057] In a further embodiment, a specific configuration of a quick plug 58 is provided, referring to Figure 6 , Figure 7 and Figure 8 The quick plug 58 includes a central tube 581, wherein the central tube 581 is provided at the edge of the cover plate 53, the aperture of the upper part of the opening of the central tube 581 is reduced, and a sealing plug 582 is provided at the lower part of the opening of the central tube 581. The opening of the quick plug 58 is narrow at the top and wide at the bottom, and the sealing plug 582 is pushed into the narrow section of the opening from bottom to top under the action of the elastic member to achieve sealing, and the sealing plug 582 is always pressed against the opening of the central tube 581 through the elastic member. At the top opening position, when the plug-in sleeve 36 is sleeved on the outside of the middle tube 581 and moves downward, a pin rod 361 with an outer diameter smaller than the inner diameter of the opening of the middle tube 581 is provided in the middle of the plug-in sleeve 36. The pin rod 361 is inserted into the opening to press the sealing plug 582 downward to disengage from the narrow section of the opening, thereby completing the connection between the middle tube 581 and the plug-in sleeve 36. When the pin rod 361 and the plug-in sleeve 36 move upward and disengage, the elastic member again pushes the sealing plug 582 into the narrow section of the opening to complete the closure.

[0058] In a further embodiment, another specific configuration of the quick plug 58 is provided, in which the sealing plug 582 inside the quick plug 58 uses a spring telescopic rod as an elastic member, or uses other structures that can be deformed and shortened under pressure and can rebound and reset when the pressure is removed.

[0059] In a further embodiment, another specific configuration of the quick plug 58 is provided, in which the sealing plug 582 inside the quick plug 58 is made of all rubber material, or other materials and shapes that can be slightly deformed under pressure to better fit the inner wall of the opening of the central tube 581.

[0060] In a further embodiment, referring to Figure 6 , Figure 7 and Figure 8The main body 31 is provided with a detection channel 32, which is connected to the metering reversing valve 8. The main body 31 is provided with a pressure sensor 33 at the port of the detection channel 32. When the metering reversing valve 8 provides liquid juice puree to the main tank 51 or extracts the air in the main tank 51, the pressure of the detection channel 32 will change significantly. At this time, the pressure sensor 33 detects the pressure change and can provide a feedback signal for the downward movement of the plug-in sleeve 36. It can provide a feedback signal for the downward movement of the plug-in sleeve 36. In conjunction with the quick plug 58 position detection module and the automatic control module, the plug-in sleeve 36 and the quick plug 58 can be automatically turned on and off. Control channel 35 is opened at the main body 31 corresponding to the plug-in sleeve 36. The control channel 35 is connected to the air supply device 4 through the solenoid valve 34. After receiving the signal, the air supply device 4 provides high-pressure gas to the control channel 35 through the solenoid valve 34. The increase in air pressure inside the control channel 35 can push the plug-in sleeve 36 downward, and the structure is compact.

[0061] In a further embodiment, a reset structure of the plug sleeve 36 is provided, referring to Figure 8 The control channel 35 is provided with a cylindrical cavity with a vertical axis, and the plug-in sleeve 36 is vertically movably arranged in the cylindrical cavity. An annular flange is provided in the middle of the circumferential outer wall of the plug-in sleeve 36, and a telescopic member 362 is provided below the annular flange. When the plug-in sleeve 36 moves downward, the annular flange compresses the telescopic member 362. When the air supply equipment 4 stops working, the telescopic member 362 squeezes the annular flange to make the plug-in sleeve 36 move upward, thereby realizing autonomous resetting.

[0062] In a further embodiment, another reset structure of the plug sleeve 36 is provided, referring to Figure 7 The control channel 35 is provided with a cylindrical cavity with a vertical axis, and the plug-in sleeve 36 is vertically movably arranged in the cylindrical cavity. An annular flange is provided in the middle of the circumferential outer wall of the plug-in sleeve 36, and the vertical outer wall of the annular flange is in sliding contact with the vertical inner wall of the cylindrical cavity. A sealed cavity is formed between the lower surface of the annular flange and the inner wall of the bottom end of the cylindrical cavity. A certain amount of gas is sealed in the sealed cavity. When the plug-in sleeve 36 moves downward, the annular flange compresses the gas. Similarly, when the gas supply device 4 stops working, the gas rebounds and squeezes the annular flange to make the plug-in sleeve 36 move upward, thereby realizing self-reset, and there is no need to design a telescopic part 362, which further reduces the number of parts and can also avoid the problem of poor reset caused by elastic fatigue of the telescopic part 362.

[0063] In a further embodiment, referring to Figure 1 and Figure 3The clarification and concentration tank 5 also includes a box body 55. The box body 55 is a hollow structure. The main tank 51 and the heater 52 are sealed and wrapped by the box body 55, which protects the main tank 51 and the heater 52 and can also lock the heat dissipated from the main tank 51 and the heater 52. The middle section of the liquid pipe group 2 is in the box body 55, and the middle section of the liquid pipe group 2 can be heated, so that the liquid juice puree inside is preheated by the overflowed heat before entering the main tank 51, thereby improving the utilization rate of the heat generated by the heater 52, reducing the heating time of the liquid juice puree, and improving the clarification efficiency of the liquid juice puree.

[0064] In a further embodiment, referring to Figure 4 A rotating drive member 56 is provided on the side wall of the box body 55. The rotating drive member 56 is driven by a servo motor and can control the rotation angle to ensure that the quick plug 58 can be smoothly aligned with the plug sleeve 36 when connecting the pipeline. The rotating drive member 56 is used to drive the main tank 51 to rotate. A limiting frame 57 is installed on the inner wall of the box body 55 opposite to the rotating drive member 56. The rotating drive member 56 squeezes the main tank 51 to increase the friction force for power transmission. The limiting frame 57 squeezes from the opposite side to ensure that the axis of the main tank 51 is vertical, thereby avoiding large vibration when the main tank 51 rotates at high speed.

[0065] In a further embodiment, another solution for controlling the rotation angle of the main tank 51 is provided. The rotation drive member 56 can use an ordinary motor. A position sensor is installed directly behind or in front of the plug-in sleeve 36 to detect the position of the quick plug 58 in real time. When the quick plug 58 moves to the bottom of the plug-in sleeve 36, a feedback signal is sent to realize the positioning function.

[0066] In a further embodiment, referring to Fig.10 The box body 55 is formed with an inclined guide surface at the bottom end of the heater 52, and the lowest point of the inclined guide surface is located at the entrance of the waste pipe group 7. The heater 52 is provided with a notch at the lowest point of the inclined guide surface. After clarification, the generated solid impurities enter the sedimentation chamber 59, and smoothly enter the waste pipe group 7 under the guidance of the inclined guide surface. The lowest points of the fins 511 and the agitator 54 are located above the sedimentation chamber 59, and the lowest point of the fins 511 is located above the sedimentation chamber 59. During the centrifugation process, the solid impurities separated under the action of gravity will continue to fall. Once they are separated from the fins 511 and enter the sedimentation chamber 59, they will not continue to be carried by rapid rotation, which can avoid the separated solid impurities from being excessively disturbed, shorten the separation time, and further improve the clarification efficiency. During the distillation process, as the liquid in the juice decreases, the solids will precipitate again. At this time, the precipitated solids will settle to the position where they are separated from the fins 511, which can avoid the accumulation of the precipitated solids at the fins 511 and avoid local overheating and coking of the juice.

[0067] In a further embodiment, referring to Fig. 9A hollow interlayer 521 is provided between the inner wall of the heater 52 and the outer wall of the main tank 51. A heat exchange medium is built in the hollow interlayer 521. The heat exchange medium is liquid. The heat exchange medium with heat is continuously passed through the hollow interlayer 521 to perform water bath heating on the main tank 51. The heater 52 is located at the top and bottom ends of the hollow interlayer 521 and is provided with delivery pipes. The liquid enters the hollow interlayer 521 from the lower delivery pipe and is discharged from the hollow interlayer 521 from the upper delivery pipe. The hollow interlayer 521 can be completely filled to improve the uniformity of heating, and the slow increase of the heating temperature can be ensured to avoid local overheating caused by rapid heating. It can be suitable for heating scenes of juice puree with more colloid and fruit protein, such as apple juice, cherry juice, kiwi juice, etc.

[0068] In a further embodiment, referring to Fig.10 A hollow interlayer 521 is arranged around the inner wall of the heater 52 and the outer wall of the main tank 51, and a heating coil 522 is coiled in the hollow interlayer 521. When heating, the heating coil 522 that is powered on to heat up can quickly heat up the required temperature environment and improve the heating efficiency. The lower half of the heating coil 522 is fixedly connected to the heater 52, and the heating coil 522 directly transfers heat to the heater 52, and then heats the juice puree liquid in the lower layer of the main tank 51 to prevent the turbid juice puree liquid in the lower layer from heating up quickly and causing coking. An anti-wear sleeve is arranged between the upper half of the heating coil 522 and the outer wall of the main tank 51. The upper half of the heating coil 522 is in direct sliding contact with the outer wall of the main tank 51 to quickly conduct heat. The anti-wear sleeve is made of metal material, which is anti-wear and has good thermal conductivity. The clearer juice puree liquid in the middle and upper layers is heated, so that the clear juice puree liquid in the upper layer can continue to boil and volatilize, thereby improving the distillation efficiency.

[0069] The working principle of this embodiment is as follows:

[0070] When adding liquid juice puree, the liquid pipe group 2 attracts the liquid juice puree through the pump, the metering reversing valve 8 is opened to allow the liquid juice puree to pass through the position of the pipeline connector 3, the pressure sensor 33 detects that the pressure inside the pipeline increases, the solenoid valve 1 34 is opened, and the high-pressure gas generated by the gas supply device 4 drives the plug-in sleeve 36 downward to connect with the quick plug 58, and the solenoid valve 2 38 of the pipeline connector 3 is opened to allow the liquid juice puree to pass through the plug-in sleeve 36 position to introduce the liquid juice puree into the main tank 51;

[0071] During the clarification of the liquid juice pulp, after a certain amount of the liquid juice pulp enters the main tank 51, the solenoid valve 2 38 is first disconnected to cut off the liquid juice pulp, and the remaining liquid juice pulp in the pipeline connector 3 continues to enter the main tank 51. The solenoid valve 1 34 then disconnects the plug sleeve 36 and resets upward to separate from the quick plug 58. The sealing plug 582 in the quick plug 58 resets to seal the main tank 51. Subsequently, the rotary drive member 56 drives the main tank 51 to rotate at a high speed for centrifugal clarification. The fins 511 increase the contact area with the liquid juice pulp so that the liquid juice pulp is quickly driven to a high-speed rotation state. The heater 52 provides temperature to heat the liquid juice pulp and make it easier to flow, shortening the centrifugal time. After multiple rotations, stops, and restarts, the separated solid impurities will enter the sedimentation chamber 59 due to gravity, and can be uniformly discharged by opening the waste pipe group 7.

[0072] When the juice concentrate is distilled, in order to avoid high temperature from damaging the flavor of the juice concentrate, the gas pipe group 6 is connected to the main tank 51 through the pipe connector 3 before heating, and the main tank 51 is vacuumed. The main tank 51 does not rotate during the whole process, and the distillation is carried out in a vacuum state. The juice concentrate is heated by the heater 52 in the vacuum state for distillation, which can reduce the temperature required for distillation. The clarified juice concentrate has less colloid inside, which reduces the adhesion of colloid on the inner wall of the main tank 51, and controls the effect of high-temperature coking of colloid on the taste. The juice concentrate has better fluidity, flows smoothly and heats up quickly under the promotion of the stirrer 54, and has a high distillation rate.

[0073] After the distillation, the pipe connector 3 controls the plug sleeve 36 to engage with the quick plug 58 again, and the metering reversing valve 8 is connected to the gas pipe group 6 to lead out the steam of the distilled juice, and uniformly cool and collect to obtain concentrated juice, so as to add it to the canned food to enrich the taste of the product. The heating is stopped when the remaining juice puree in the main tank 51 reaches a quarter of the volume. Compared with the traditional distillation, the heating is stopped when the volume is half, which avoids the waste of raw materials. The clarified juice puree has less colloid inside and can meet the requirements of deep distillation, avoiding the undesirable phenomenon of coking of traditional juice puree during deep distillation.

[0074] Finally, the main tank 51 and the agitator 54 rotate in the opposite direction, and the remaining juice puree is used to self-clean and rinse the inner wall of the main tank 51. Clean water can also be introduced through the liquid pipe group 2 to assist in washing away attachments, and the residual liquid is discharged through the waste pipe group 7 to wait for the next clarification and concentration work.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
