Description

Technical Field

[0001] The present invention relates to the technical field of yogurt processing equipment, and particularly relates to a yogurt stirring device for yogurt processing. Background Art

[0002] Yogurt is a dairy product made from milk. After pasteurization, beneficial bacteria are added to the milk, and after fermentation, it is cooled and filled. Currently, most yogurt products on the market are solidified, stirred, or fruit-flavored with various fruit juices and jams added as accessories. Yogurt not only retains all the advantages of milk, but also makes up for its weaknesses in some aspects during the processing, becoming a more suitable nutritional health product for humans. During the industrial production of yogurt as food, yogurt stirring equipment is often used to stir the fermenting yogurt.

[0003] The existing yogurt stirring equipment for yogurt processing mainly consists of a mixing tank with its own legs, a feeding hopper installed on the mixing tank, a discharge pipe installed in the middle of the bottom end of the mixing tank, and a constant-speed stirring mechanism installed inside the mixing tank. When this kind of yogurt stirring equipment is in use, the raw materials for yogurt processing are first added into the mixing tank through the feeding hopper, and then the yogurt raw materials are mixed under the action of the constant-speed stirring mechanism.

[0004] Although the existing yogurt stirring equipment for yogurt processing can achieve the mixing and processing of yogurt processing raw materials, during the processing, as the stirring continues, the yogurt raw materials will gradually settle downward, resulting in uneven concentration of the yogurt raw materials on the upper and lower sides in the mixing tank after mixing, thus making the mixing quality of the yogurt poor. At the same time, when discharging the yogurt after stirring, due to the yogurt being relatively viscous, a part of the yogurt will adhere to the inside of the device, causing waste of yogurt residue. Summary of the Invention

[0005] The purpose of the present invention is to provide a yogurt stirring device for yogurt processing in order to solve the above problems.

[0006] The present invention achieves the above purpose through the following technical solutions:

[0007] A yogurt stirring device for yogurt processing, including a mixing tank, a differential mixing mechanism is installed in the middle of the mixing tank. The differential mixing mechanism includes an inner shaft, a first gear, a motor, a support plate, a differential gear shaft, a second gear, an outer shaft, a third gear, a fourth gear and a mixing frame. A high-pressure blowing mechanism is installed around the top of the mixing tank. The high-pressure blowing mechanism includes an electric telescopic rod, a high-pressure air pump, a clean air connecting pipe, a support plate, a jet ring cover and a nozzle. Among them, the outer shaft is installed in the middle of the top of the mixing tank. The second gear is located on the upper side of the outer wall of the outer shaft. The inner shaft is rotatably installed in the outer shaft, and the top of the inner shaft extends out of the outer shaft. The top of the inner shaft is connected with the first gear. The first gear and one side of the second gear are jointly connected with the differential gear shaft. The top of the differential gear shaft is connected with the motor. The bottom of the motor is installed on the support plate. The bottom of the support plate is connected with the mixing tank. There are three third gears, and the three third gears are installed outside the inner shaft from top to bottom. Each side of the third gear is connected with the fourth gear. The middle of the side wall of the fourth gear facing away from the third gear is connected with the mixing frame; There are three electric telescopic rods, and the three electric telescopic rods are annularly distributed at the top of the mixing tank. The top of the jet ring cover is connected with the telescopic part of each electric telescopic rod. The jet ring cover is located at the inner top of the mixing tank. There are two groups of nozzles, and the two groups of nozzles are respectively located at the lower parts of the inner and outer sides of the jet ring cover. The support plate is welded to the upper part of the outer wall of the mixing tank. The high-pressure air pump is connected with the support plate. The clean air connecting pipe is connected with the air inlet of the high-pressure air pump.

[0008] Further, the support plate is of an inverted L-shaped structure. The motor is bolted to the support plate, and the motor is connected to the differential gear shaft by a coupling.

[0009] By adopting the above technical solution, the support plate is mainly used to provide an installation foundation for the motor, and the motor is mainly used to provide power for the rotation of the differential gear shaft.

[0010] Further, the differential gear shaft is composed of a rotating shaft, a large gear installed on the upper part of the rotating shaft and a small gear installed on the lower part of the rotating shaft.

[0011] By adopting the above technical solution, after the differential gear shaft rotates under the action of the motor, the power of the motor can be transmitted to the inner shaft and the outer shaft in a variable speed manner.

[0012] Further, the size of the first gear is smaller than that of the second gear. The first gear meshes with the large gear on the differential gear shaft, and the second gear meshes with the small gear on the differential gear shaft.

[0013] By adopting the above technical solution, the first gear is meshed with the large gear on the differential gear shaft, and at the same time, the second gear is meshed with the small gear on the differential gear shaft, which can ensure that when the differential gear shaft rotates, the rotation speed of the inner shaft is greater than that of the outer shaft. After the outer shaft rotates, the mixing frame can revolve around the center of the outer shaft, and after the inner shaft rotates, the mixing frame will rotate around its own axis, realizing the flipping and mixing of the materials on the upper and lower sides in the mixing tank.

[0014] Further, the third gear is welded to the inner shaft, the third gear is meshed with the fourth gear, and the mixing frame is welded to the fourth gear.

[0015] By adopting the above technical solution, welding and fixing the third gear on the inner shaft can ensure the synchronous rotation of the third gear with the inner shaft. After the third gear rotates, the power can be transmitted to the mixing frame through the fourth gear.

[0016] Further, the mixing frame is composed of a short shaft and stirring blades installed on the outer wall of the short shaft, and the mixing shaft is rotationally and hermetically connected to the outer shaft.

[0017] By adopting the above technical solution, after the mixing frame rotates, the yogurt raw materials in the mixing tank can be flipped and stirred up and down, ensuring the full mixing of the yogurt raw materials.

[0018] Further, the fixed part of the electric telescopic rod is bolted to the mixing tank, and the telescopic part of the electric telescopic rod is bolted to the jet ring cover.

[0019] By adopting the above technical solution, after the electric telescopic rod is started, the jet ring cover can move up and down along the inner wall of the mixing tank, so as to fully blow and discharge the adhered yogurt in the mixing tank while the jet ring cover moves up and down.

[0020] Further, the high-pressure air pump is connected to the jet ring cover through a pipeline, and the nozzles are distributed obliquely downward on both the inner and outer sides of the jet ring cover.

[0021] By adopting the above technical solution, setting the nozzles obliquely downward can ensure that the gas ejected from the nozzles can be sprayed on all parts of the mixing tank.

[0022] Further, an operation panel is also installed on one side wall of the mixing tank, and the operation panel is electrically connected to the motor, the high-pressure air pump, and the electric telescopic rod.

[0023] By adopting the above technical solution, the operation panel mainly plays the role of a switch, and the operation panel mainly controls the orderly operation of the motor, the high-pressure air pump and the electric telescopic rod by controlling the on-off of the circuit.

[0024] Furthermore, three legs are welded in a ring shape on the periphery of the bottom end of the mixing tank, a discharge pipe with a valve is installed in the middle of the bottom end of the mixing tank, and a feeding hopper is welded at the feed inlet at the top end of the mixing tank.

[0025] By adopting the above technical solution, the yogurt processing raw materials can be conveniently added to the mixing tank through the feeding hopper, and the yogurt after mixing and fermentation in the mixing tank can be conveniently discharged with the help of the discharge pipe.

[0026] The specific working principle is as follows: when mixing, firstly, the raw materials for yogurt processing are added into the mixing tank through the feeding hopper, and then the differential gear shaft is rotated under the action of the motor. After the differential gear shaft rotates, on the one hand, the outer shaft is rotated under the action of the gear two, and the outer shaft drives the mixing frame to revolve along the center of the outer shaft. On the other hand, the inner shaft is rotated under the action of the gear one, and after the inner shaft rotates, the mixing frame is rotated around its own axis under the action of the gear three and the gear four, so that in the process of mixing and stirring the yogurt raw materials, uniform mixing of the yogurt raw materials on the upper and lower sides is achieved, ensuring the final mixed fermentation quality of the yogurt in the mixing tank, and in the When the yogurt in the mixing tank is discharged after fermentation, the discharge pipe is directly opened so that the yogurt produced in the mixing tank can be smoothly discharged into the external container. In the discharge process, the clean air pipe is connected to the air outlet pipe on the air equipment so that clean air can be sprayed into the mixing tank through the nozzle on the jet ring cover under the action of the high-pressure air pump, so as to discharge the residual yogurt adhering to the mixing tank. In the blowing process, the jet ring cover can be lifted up and down along the inner wall of the mixing tank under the action of the electric telescopic rod, so that the yogurt adhering to various parts of the mixing tank can be conveniently discharged during the lifting process, thereby reducing the waste of yogurt adhesion.

[0027] The beneficial effects of the present invention are:

[0028] 1. By installing a differential mixing mechanism composed of an inner shaft, a gear 1, a motor, a support plate, a differential gear shaft, a gear 2, an outer shaft, a gear 3, a gear 4 and a mixing frame on the mixing tank, when the yogurt raw materials are stirred and mixed, the mixing frame can be rotated up and down to mix the yogurt raw materials in the mixing tank through the revolution of the mixing frame around the center of the outer shaft and the rotation of the mixing frame itself, ensuring that the yogurt raw materials on the upper and lower sides of the mixing tank are mixed more evenly, thereby improving the stirring and mixing quality of the yogurt raw materials;

[0029] 2. By installing a high-pressure spraying mechanism composed of an electric telescopic rod, a high-pressure air pump, a clean air connecting pipe, a support plate, a jet ring cover, and a nozzle at the top of the mixing tank, when discharging the mixed yogurt raw materials, the high-pressure air pump and the clean air connecting pipe can be used to transport the externally purified clean air to the jet ring cover, so that after the clean air is ejected from the nozzles on the jet ring cover, the yogurt adhering to the inside of the device can be effectively blown off, reducing the residual waste of yogurt inside the device.

[0037] The present invention will be further described below with reference to the drawings:

[0038] As Figures 1 - 5As shown in the figure, a yogurt stirring device for yogurt processing includes a mixing tank 6. A differential mixing mechanism 7 is installed in the middle of the mixing tank 6.

The high-pressure blowing mechanism 1 includes an electric telescopic rod 101, a high-pressure air pump 102, a clean air connection pipe 103, a support plate 104, a jet ring cover 105, and a nozzle 106. Among them, the outer shaft 707 is installed in the middle of the top of the mixing tank 6. The second gear 706 is located on the upper side of the outer wall of the outer shaft 707. The inner shaft 701 is rotatably installed in the outer shaft 707, and the top of the inner shaft 701 extends out of the outer shaft 707. The top of the inner shaft 701 is connected to the first gear 702. The first gear 702 and one side of the second gear 706 are jointly connected to the differential gear shaft 705. The top of the differential gear shaft 705 is connected to the motor 703. The bottom of the motor 703 is installed on the support plate 104. The bottom of the support plate 104 is connected to the mixing tank 6. There are three third gears 708, and the three third gears 708 are installed outside the inner shaft 701 from top to bottom. Each side of the third gear 708 is connected to a fourth gear 709. The middle of the side wall of the fourth gear 709 facing away from the third gear 708 is connected to the mixing frame 710. When stirring and mixing the yogurt raw materials, through the revolution of the mixing frame 710 around the center of the outer shaft 707 and the rotation of the mixing frame 710 itself, the yogurt raw materials in the mixing tank 6 are turned over and mixed up and down, ensuring that the yogurt raw materials on the upper and lower sides in the mixing tank 6 are mixed more evenly, so that the stirring and mixing quality of the yogurt raw materials is better. There are three electric telescopic rods 101, and the three electric telescopic rods 101 are annularly distributed at the top of the mixing tank 6. The top of the jet ring cover 105 is connected to the telescopic part of each electric telescopic rod 101. The jet ring cover 105 is located at the inner top of the mixing tank 6. There are two groups of nozzles 106, and the two groups of nozzles 106 are respectively located at the lower parts inside and outside the jet ring cover 105. The support plate 104 is welded to the upper part of the outer wall of the mixing tank 6. The high-pressure air pump 102 is connected to the support plate 104. The clean air connection pipe 103 is connected to the air inlet of the high-pressure air pump 102. When discharging the yogurt raw materials after mixing, with the help of the high-pressure air pump 102 and the clean air connection pipe 103, the externally purified clean air is transported to the jet ring cover 105, so that after the clean air is ejected from the nozzles 106 on the jet ring cover 105, the yogurt adhering to the inside of the device can be effectively blown off, reducing the residual waste of yogurt inside the device.

[0039] In this embodiment, the support plate 104 is of an inverted L-shaped structure. The motor 703 is bolted to the support plate 104. The motor 703 is connected to the differential gear shaft 705 by a coupling. The support plate 104 is mainly used to provide an installation foundation for the motor 703, and the motor 703 is mainly used to provide power for the rotation of the differential gear shaft 705.

[0040] In this embodiment, the differential gear shaft 705 is composed of a rotating shaft, a large gear mounted on the upper part of the rotating shaft, and a small gear mounted on the lower part of the rotating shaft. After the differential gear shaft 705 rotates under the action of the motor 703, the power of the motor 703 can be transmitted to the inner shaft 701 and the outer shaft 707 with speed change.

[0041] In this embodiment, the size of the first gear 702 is smaller than that of the second gear 706. The first gear 702 meshes with the large gear on the differential gear shaft 705, and the second gear 706 meshes with the small gear on the differential gear shaft 705. By making the first gear 702 mesh with the large gear on the differential gear shaft 705 and at the same time making the second gear 706 mesh with the small gear on the differential gear shaft 705, it can be ensured that when the differential gear shaft 705 rotates, the rotation speed of the inner shaft 701 is greater than that of the outer shaft 707. After the outer shaft 707 rotates, the mixing frame 710 can perform a revolution around the center of the outer shaft 707, and after the inner shaft 701 rotates, the mixing frame 710 will perform a rotation around its own axis, realizing the flipping and mixing of the materials on the upper and lower sides in the mixing tank 6.

[0042] In this embodiment, the third gear 708 is welded to the inner shaft 701, the third gear 708 meshes with the fourth gear 709, and the mixing frame 710 is welded to the fourth gear 709. By welding and fixing the third gear 708 on the inner shaft 701, it can be ensured that the third gear 708 rotates synchronously with the inner shaft 701. After the third gear 708 rotates, the power can be transmitted to the mixing frame 710 through the fourth gear 709.

[0043] In this embodiment, the mixing frame 710 is composed of a short shaft and stirring blades mounted on the outer wall of the short shaft. The mixing shaft is rotationally and sealingly connected to the outer shaft 707. After the mixing frame 710 rotates, it can realize the up-and-down flipping and stirring of the yogurt raw materials in the mixing tank 6, ensuring the full mixing of the yogurt raw materials.

[0044] In this embodiment, the fixed part of the electric telescopic rod 101 is bolted to the mixing tank 6, and the telescopic part of the electric telescopic rod 101 is bolted to the jet ring cover 105. After the electric telescopic rod 101 is started, the jet ring cover 105 can move up and down along the inner wall of the mixing tank 6, so as to fully blow and discharge the adhered yogurt in the mixing tank 6 while the jet ring cover 105 moves up and down.

[0045] In this embodiment, the high-pressure air pump 102 is connected to the jet ring cover 105 through a pipeline. The nozzles 106 are respectively inclined downward on both sides inside and outside the jet ring cover 105. By setting the nozzles 106 to be inclined downward, it can be ensured that the gas ejected from the nozzles 106 can be sprayed on various parts of the mixing tank 6.

[0046] In this embodiment, an operation panel 3 is also installed on one side wall of the mixing tank 6. The operation panel 3 is electrically connected to the motor 703, the high-pressure air pump 102, and the electric telescopic rod 101. The operation panel 3 mainly functions as a switch, and mainly controls the orderly operation of the motor 703, the high-pressure air pump 102, and the electric telescopic rod 101 by controlling the on-off of the circuit.

[0047] In this embodiment, three legs 4 are welded annularly around the bottom end of the mixing tank 6. A discharge pipe 5 with a self-contained valve is installed in the middle of the bottom end of the mixing tank 6. A feeding hopper 2 is also welded at the feeding port at the top end of the mixing tank 6. Through the feeding hopper 2, the raw materials for yogurt processing can be conveniently added to the mixing tank 6, and with the help of the discharge pipe 5, the yogurt after mixing and fermentation in the mixing tank 6 can be conveniently discharged.

[0048] The specific working principle is as follows: During mixing, first, the raw materials for yogurt processing are added into the mixing tank 6 through the feeding hopper 2, and then the differential gear shaft 705 is rotated under the action of the motor 703. After the differential gear shaft 705 rotates, on the one hand, the outer shaft 707 will be rotated under the action of the gear two 706. After the outer shaft 707 rotates, it will drive the mixing frame 710 to revolve around the center of the outer shaft 707. On the other hand, the inner shaft 701 will be rotated under the action of the gear one 702. After the inner shaft 701 rotates, the mixing frame 710 will be rotated around its own axis under the action of the gear three 708 and the gear four 709. Thus, during the mixing and stirring process of the yogurt raw materials, the yogurt raw materials on the upper and lower sides are evenly mixed, ensuring the final mixing and fermentation quality of the yogurt in the mixing tank 6. When the fermented yogurt in the mixing tank 6 is discharged, the discharge pipe 5 is directly opened so that the produced yogurt in the mixing tank 6 can be smoothly discharged into an external container. During the discharging process, the clean air connection pipe 103 is connected to the air outlet pipe on the air equipment, so that under the action of the high-pressure air pump 102, clean air can be sprayed inside the mixing tank 6 through the nozzles 106 on the jet ring cover 105 to discharge the yogurt adhered and remaining inside the mixing tank 6. During the blowing process, under the action of the electric telescopic rod 101, the jet ring cover 105 can be lifted and lowered along the inner wall of the mixing tank 6, so that during the up and down movement, the yogurt adhered to each part inside the mixing tank 6 can be conveniently discharged, reducing the adhesion and waste of yogurt.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
