A constant-temperature mixing and stirring process for fruit juice and its double-layer heat-insulating stirring device

Abstract

This invention discloses a constant-temperature mixing and stirring process for fruit juice and its double-layer heat-insulating stirring device, relating to the field of fruit juice stirring technology. It includes a stirring tank, with a motor fixedly connected to the top of the tank, and a drive shaft fixedly connected to the motor's output end. Through the adjustment unit, the drive shaft rotates, causing a fixed cylinder and a sliding piston rod to rotate circumferentially. A squeezing rod, via a cylindrical rod, drives the sliding piston rod into the fixed cylinder. The movement of the sliding piston rod forces the oil in the fixed cylinder into a fixed tube, causing the oil to squeeze the sliding rod and, through a connecting rod, rotate the sliding filter plate and the rotating filter plate. Simultaneously, the sliding filter plate moves outward, increasing the tilt angle of the rotating filter plate. This makes it easier for the fruit juice to flow and flush the pulp into the filter cylinder. Furthermore, the filter holes on the rotating and sliding filter plates are misaligned, reducing their size and improving the interception effect on the pulp, thus ensuring that the pulp is fully flushed into the filter cylinder.

Description

Technical Field

[0001] This invention relates to the field of fruit juice mixing technology, and in particular to a constant temperature mixing and stirring process for fruit juice and its double-layer heat preservation mixing device. Background Technology

[0002] In the production of fruit juice, constant-temperature mixing is a crucial step to achieve a uniform texture, stable suspension, and consistent color and flavor. To further process larger fruit pulp particles and improve the smoothness of the texture, many machines integrate or separately install chopping blades on the mixing shaft to break down the pulp while mixing.

[0003] A search revealed Chinese patent CN113617240B, which discloses a mixing and stirring device for fruit juice beverage production. The device includes a stirring cylinder with a main shaft movably connected inside. The stirring cylinder contains a ring of hollow plates arranged around the main shaft. The hollow plates are fixedly connected to the main shaft via support rods. Each hollow plate has two holes, one and two, on its two sides. The diameter of hole one is larger than that of hole two. The lower end of each hollow plate connects to a collection tank. A sliding plate is inserted into the lower end of the collection tank. The sliding plate has several holes three with the same diameter as hole two. A discharge pipe is fixedly connected to the lower side wall of the stirring cylinder, and a discharge valve is installed on the discharge pipe.

[0004] However, the above invention has the following shortcomings: During the mixing process of existing juices, the high-speed rotating blades cause the juice inside the tank to form a strong vortex. Under the combined action of centrifugal force and liquid viscosity, the pulp particles rotate as a whole with the vortex and tend to move towards the tank wall. This movement mode causes the pulp particles to disperse and flow inside the mixing tank, and cannot stably and centrally pass through the effective working area of ​​the cutting blades. They only pass through the blade area for a short time or irregularly, resulting in insufficient cutting and inadequate cutting. Some larger pulp particles may even circulate on the periphery, completely avoiding the cutting action of the blades. As a result, after mixing, a large number of large pulp particles that have not been sufficiently cut remain in the finished juice. Summary of the Invention

[0017] The present invention also provides a constant temperature mixing and stirring process for fruit juice, which includes the following steps:

[0019] Step 2: Start the motor to drive the stirring mechanism to mix the juice; during the stirring process, the crushing unit can crush larger pieces of fruit pulp in the juice;

[0020] Step 3: After mixing, the juice can be dispensed.

[0021] This invention provides an improved constant-temperature mixing and stirring process for fruit juice and its double-layer heat-insulating stirring device, which has the following improvements and advantages compared with the prior art:

[0022] Firstly, this invention, through the setting of the adjustment unit, drives the fixed cylinder and sliding piston rod to rotate in a circular motion. When the rotating sliding piston rod causes the cylindrical rod to contact the extrusion rod, the extrusion rod drives the sliding piston rod into the fixed cylinder through the cylindrical rod. The movement of the sliding piston rod forces the oil in the fixed cylinder into the through groove through the connecting pipe and the liquid inlet groove, and then into the fixed pipe through the rotating pipe, causing the oil to extrude the sliding rod outward. The movement of the sliding rod drives the sliding filter plate and the rotating filter plate to rotate around the rotating shaft through the connecting rod. At the same time, the sliding filter plate moves outward, thereby increasing the tilt angle of the rotating filter plate, making it easier for the juice to flow and flush the pulp into the filter cylinder. Furthermore, the filter holes on the rotating filter plate and the sliding filter plate are misaligned, making the filter holes smaller and improving the interception effect of the pulp, thus fully flushing the pulp into the filter cylinder.

[0023] Secondly, in this invention, the motor drives the drive shaft to rotate, which in turn drives the fixed rod and the filter cylinder to rotate in a circular motion. The rotation of the fixed rod causes the rotating shaft, the rotating filter plate, and the sliding filter plate to rotate. The filter holes of the rotating filter plate and the sliding filter plate are aligned, which stirs the filter. The rotating filter plate can block larger pieces of fruit pulp in the juice. Since the rotating filter plate is tilted, the juice flows along the direction of the rotating filter plate, flushing the larger pieces of fruit pulp into the filter cylinder, thus concentrating the larger pieces of fruit pulp.

[0024] Thirdly, the present invention improves the effect of flushing fruit pulp into the filter cylinder by setting up an air blowing unit, which moves a sliding piston rod to squeeze the gas in the fixed cylinder through a one-way air outlet pipe, an installation pipe and a connecting hose, and then sprays it out from the air outlet.

[0025] Fourthly, this invention, through the setting of the crushing unit, causes the filter cylinder to rotate, driving the guide rod, sliding block, and rotating rod to rotate in a circular motion. The rotating rod then drives the gear column to rotate on the ring rack and rotate on its own axis. The rotation of the gear column drives the rotating rod and the cutter to rotate. The rotation of the cutter can crush larger pieces of fruit pulp in the filter cylinder, thus achieving the crushing of fruit pulp concentrated in the filter cylinder. The rotation of the filter plate drives the rotating shaft to rotate, which in turn drives the inclined block to rotate. The rotation of the inclined block can drive the fixed cylinder and sliding block to move upward. The movement of the sliding block drives the rotating rod and gear column to move, and the movement of the rotating rod drives the cutter to move upward. This allows for adjustment of the cutter's position, thereby improving the crushing effect on the fruit pulp. Attached Figure Description

[0038] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides an improved, temperature-controlled, double-layered, heat-insulating stirring device for fruit juice. The technical solution of this invention is as follows:

[0040] Example 1:

[0041] like Figures 1 to 9 As shown, this embodiment of the invention provides a constant temperature mixing and stirring process for fruit juice and its double-layer heat preservation stirring device, including a stirring tank 1, a motor 11 fixedly connected to the top of the stirring tank 1, a drive shaft 12 fixedly connected to the output end of the motor 11, and the drive shaft 12 rotatably connected to the stirring tank 1.

[0042] A stirring mechanism is located on the drive shaft 12;

[0043] The stirring mechanism includes an adjustment unit, a crushing unit, and an air blowing unit. The adjustment unit includes two fixed rods 13 fixedly connected to the drive shaft 12. A filter cylinder 14 is fixedly connected to one end of each of the two fixed rods 13. A rotating shaft 15 is rotatably connected to each of the two fixed rods 13. A rotating filter plate 16 is fixedly connected to the bottom end of each of the two rotating shafts 15. A sliding filter plate 17 is slidably connected to each of the two rotating filter plates 16. A connecting rod 111 is fixedly connected to each of the two sliding filter plates 17. A rotating tube 18 is rotatably connected to each of the two fixed rods 13. A fixed tube 19 is fixedly connected to the top end of each of the two rotating tubes 18. A sliding rod 110 is slidably connected to each of the two fixed tubes 19. The top ends of the two connecting rods 111 are respectively fixedly connected to one end of each of the two sliding rods 110. A fixed cylinder 4 is fixedly connected to the drive shaft 12. A sliding piston rod 41 is slidably connected to the fixed cylinder 4. A connecting tube 42 is fixedly connected to the fixed cylinder 4. An inlet groove 43 is provided inside. Two fixed rods 13 each have a through groove 44 at their close ends. One end of a connecting pipe 42 is connected to the inlet groove 43, and both through grooves 44 are connected to the inlet groove 43. Two rotating pipes 18 are connected to the two through grooves 44 respectively. Through the sliding filter plate 17, the motor 11 drives the drive shaft 12 to rotate. The drive shaft 12 drives the fixed rods 13 and the filter cylinder 14 to rotate circumferentially. The rotation of the fixed rods 13 drives the rotating shaft 15, the rotating filter plate 16, and the sliding filter plate 17 to rotate. The filter holes of the rotating filter plate 16 and the sliding filter plate 17 are aligned, causing the filtration of the rotating filter plate 16 and the sliding filter plate 17 to be stirred. The rotating filter plate 16 can block larger pieces of fruit pulp in the juice. Because the rotating filter plate 16 is tilted, the juice flows along the direction of the rotating filter plate 16, flushing larger pieces of fruit pulp into the filter cylinder 14, thus concentrating the larger pieces of fruit pulp.

[0044] Furthermore, a cylindrical rod 46 is fixedly connected to one end of the sliding piston rod 41, and a pressing rod 47 is fixedly connected to the inner wall of the top of the mixing tank 1. The pressing rod 47 contacts the cylindrical rod 46. A fixed baffle 48 is fixedly connected to the inner wall of the fixed cylinder 4, and a movable baffle 49 is slidably connected to the fixed baffle 48. One end of the movable baffle 49 is fixedly connected to the sliding piston rod 41. The fixed cylinder 4 is provided with an oil chamber and an air chamber, and the other end of the connecting pipe 42 is connected to the oil chamber. Through the setting of the adjustment unit, the drive shaft 12 rotates to drive the fixed cylinder 4 and the sliding piston rod 41 to rotate in a circular motion. When the sliding piston rod 41 rotates and drives the cylindrical rod 46 to contact the pressing rod 47, the pressing rod 47 drives the sliding piston rod 41 into the fixed cylinder through the cylindrical rod 46. Inside the filter cylinder 14, the sliding piston rod 41 moves to squeeze the oil in the fixed cylinder 4 into the through groove 44 through the connecting pipe 42 and the liquid inlet 43, and then into the fixed pipe 19 through the rotating pipe 18. This causes the oil to squeeze the sliding rod 110 outward. The movement of the sliding rod 110 drives the sliding filter plate 17 and the rotating filter plate 16 to rotate around the rotating shaft 15 via the connecting rod 111. At the same time, the sliding filter plate 17 moves outward, which increases the tilt angle of the rotating filter plate 16, making it easier for the juice to flow and flush the pulp into the filter cylinder 14. The filter holes on the rotating filter plate 16 and the sliding filter plate 17 are misaligned, making the filter holes smaller and improving the interception effect of the pulp, so that the pulp can be fully flushed into the filter cylinder 14.

[0045] Furthermore, a telescopic spring 45 is sleeved on the sliding piston rod 41, and the two ends of the telescopic spring 45 are fixedly connected to the fixed cylinder 4 and the sliding piston rod 41 respectively. By setting the telescopic spring 45, when the cylindrical rod 46 moves away from the extrusion rod 47, the telescopic spring 45 drives the sliding piston rod 41 to reset.

[0046] Furthermore, the air blowing unit includes a one-way air outlet pipe 5 fixedly connected to the fixed cylinder 4. One end of the one-way air outlet pipe 5 is connected to the air chamber, and the bottom end of the one-way air outlet pipe 5 is fixedly connected to the mounting pipe 51. Air jet pipes 53 are fixedly connected to both sliding filter plates 17. The two air jet pipes 53 are respectively fixedly connected to the two ends of the mounting pipe 51 by connecting hoses 52. With the setting of the air blowing unit, the sliding piston rod 41 moves to squeeze the gas in the fixed cylinder 4 into the air jet pipe 53 through the one-way air outlet pipe 5, the mounting pipe 51 and the connecting hose 52, and then spray it out from the air jet pipe 53, which improves the effect of flushing the pulp into the filter cylinder 14.

[0047] Furthermore, a one-way air inlet pipe 54 is fixedly connected to the fixed cylinder 4, and the one-way air inlet pipe 54 is connected to the air chamber; through the setting of the one-way air inlet pipe 54, when the sliding piston rod 41 moves outward, air enters the fixed cylinder 4 through the one-way air inlet pipe 54.

[0048] Furthermore, the pulverizing unit includes two guide rods 2 fixedly connected to the tops of two filter cylinders 14, with a sliding block 21 slidably connected to each pair of guide rods 2. A rotating rod 22 is rotatably connected to the sliding block 21, and multiple cutters 28 are fixedly connected to the rotating rod 22, all located inside the filter cylinder 14. A gear column 23 is fixedly connected to the top of the rotating rod 22, and a ring rack 24 is fixedly connected to the inner wall of the mixing tank 1, meshing with the gear column 23. A fixed cylinder 26 is fixedly connected to the sliding block 21, and a beveled block 27 is fixedly connected to the top of the rotating shaft 15, contacting the fixed cylinder 26. A feed inlet is provided on the filter cylinder 14. Through the arrangement of the pulverizing unit, the rotation of the filter cylinder 14 drives the guide rods 2... The sliding block 21 and the rotating rod 22 rotate in a circular motion. The rotation of the rotating rod 22 drives the gear column 23 to rotate on the ring rack 24 and rotate on its own axis. The rotation of the gear column 23 drives the rotating rod 22 and the cutter 28 to rotate. The rotation of the cutter 28 can crush larger pieces of fruit pulp in the filter cylinder 14, thus crushing the fruit pulp concentrated in the filter cylinder 14. The rotation of the filter plate 16 drives the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 drives the inclined block 27 to rotate. The rotation of the inclined block 27 can drive the fixed cylinder 26 and the sliding block 21 to move upward. The movement of the sliding block 21 drives the rotating rod 22 and the gear column 23 to move. The movement of the rotating rod 22 drives the cutter 28 to move upward, thereby adjusting the position of the cutter 28 and improving the crushing effect of the fruit pulp.

[0049] Furthermore, a return spring 25 is sleeved on each of the two guide rods 2, and the two ends of the return spring 25 are fixedly connected to the guide rod 2 and the sliding block 21 respectively; by setting the return spring 25, the return spring 25 can drive the sliding block 21, the rotating shaft 15 and the cutter 28.

[0050] Furthermore, a sliding plate 3 is slidably connected to the filter cylinder 14, and a fixed block 31 is fixedly connected to the sliding plate 3. A connecting rod 32 is rotatably connected to the rotating filter plate 16, and one end of the connecting rod 32 is rotatably connected to the fixed block 31. With the setting of the sliding plate 3, the rotating filter plate 16 rotates and drives the fixed block 31 and the sliding plate 3 to move through the connecting rod 32, so that the sliding plate 3 enters the fixed cylinder 4, thereby increasing the feed opening of the fixed cylinder 4, so that the pulp can fully enter the filter cylinder 14.

[0051] Furthermore, a feed pipe 6 is fixedly connected to the mixing tank 1, and a discharge pipe 7 is fixedly connected to the bottom of the mixing tank 1. Through the setting of the feed pipe 6, the juice is put into the mixing tank 1 through the feed pipe 6, and through the setting of the discharge pipe 7, the mixed juice can be discharged from the discharge pipe 7.

[0052] Example 2:

[0053] This embodiment also discloses a constant-temperature mixing and stirring process for fruit juice, which includes the following steps:

[0054] Step 1: Pour the juice ingredients into the mixing tank 1 and keep the juice at a constant temperature;

[0055] Step 2: Start motor 11 to drive the stirring mechanism to mix the juice; during the stirring process, the crushing unit can crush larger pieces of fruit pulp in the juice;

[0056] Step 3: After mixing, the juice can be dispensed.

[0057] Working principle: Juice is fed into the mixing tank 1 through the feed pipe 6. The motor 11 drives the drive shaft 12 to rotate, which in turn drives the fixed rod 13 and the filter cylinder 14 to rotate in a circular motion. The rotation of the fixed rod 13 drives the rotating shaft 15, the rotating filter plate 16, and the sliding filter plate 17 to rotate in a circular motion. The filter holes of the rotating filter plate 16 and the sliding filter plate 17 are aligned, which stirs the filtration process. The rotating filter plate 16 can block larger pieces of fruit pulp in the juice. Since the rotating filter plate 16 is tilted, the juice flows along the direction of the rotating filter plate 16, pushing the larger pieces of fruit pulp into the filter cylinder 14. The rotation of the filter cylinder 14 drives the guide rod 2, the sliding block 21, and the rotating rod 22 to rotate in a circular motion. The rotating rod 22 drives the gear column 23 to rotate on the ring rack 24 and rotate on its own axis. The rotation of the gear column 23 drives the rotating rod 22 and the cutter 28 to rotate. The rotation of the cutter 28 can crush larger pieces of fruit pulp in the filter cylinder 14. The drive shaft 12 rotates, causing the fixed cylinder 4 and the sliding piston rod 41 to rotate circumferentially. When the rotating piston rod 41 drives the cylindrical rod 46 to contact the extrusion rod 47, the extrusion rod 47 drives the sliding piston rod 41 into the fixed cylinder 4 through the cylindrical rod 46. The movement of the sliding piston rod 41 causes the telescopic spring 45 to compress and undergo elastic deformation. At the same time, the movement of the sliding piston rod 41 forces the oil in the fixed cylinder 4 into the through groove 44 through the connecting pipe 42 and the liquid inlet 43, and then into the fixed pipe 19 through the rotating pipe 18. The oil-squeezing sliding rod 110 moves outward, and the movement of the sliding rod 110 drives the sliding filter plate 17 and the rotating filter plate 16 to rotate around the rotating shaft 15 via the connecting rod 111. At the same time, the sliding filter plate 17 moves outward, thereby increasing the tilt angle of the rotating filter plate 16, making it easier for the juice flow to flush the pulp into the filter cylinder 14. Furthermore, the filter holes on the rotating filter plate 16 and the sliding filter plate 17 are misaligned, causing the filter holes to shrink and improving the interception effect on the pulp. This allows the pulp to be fully flushed into the filter cylinder 14. The sliding piston rod 41 moves, forcing the gas in the fixed cylinder 4 through the one-way exhaust pipe 5, the mounting pipe 51, and the connecting hose 52 into the jet pipe 53, and then ejecting it from the jet pipe 53, further improving the flushing of the pulp into the filter. The effect inside cylinder 14 is as follows: when the sliding piston rod 41 moves outward, air enters the fixed cylinder 4 through the one-way air inlet pipe 54. The rotating filter plate 16 rotates, which drives the fixed block 31 and the sliding plate 3 to move via the connecting rod 32, allowing the sliding plate 3 to enter the fixed cylinder 4. This increases the feed opening of the fixed cylinder 4, making it easier for the fruit pulp to fully enter the filter cylinder 14. The rotation of the filter plate 16 drives the rotating shaft 15 to rotate, which in turn drives the inclined block 27 to rotate. The rotation of the inclined block 27 drives the fixed cylinder 26 and the sliding block 21 to move upward. The movement of the sliding block 21 compresses the return spring 25, causing it to undergo elastic deformation. The movement of the sliding block 21 drives the rotating rod 22 and the gear column 23 to move, which in turn drives the cutter 28 to move upward.This allows for adjustment of the position of the cutter 28, thereby improving the pulverization effect on the fruit pulp.
