Description

TECHNICAL FIELD

[0001] The present application relates to the field of food, in particular to an automatic stuffing device and process for steamed dumplings. BACKGROUND

[0002] Steamed dumplings have the advantages of both small steamed buns and potstickers, but the stuffing varies by region.

[0003] The current situation of stuffing in the production of steamed dumplings in the industry is that it relies on manual use of tools such as iron shovels to pour stuffing into the stuffing hopper. However, since the stuffing is in a semi-liquid state, the stuffing is easily splashed to the ground around the stuffing hopper during manual feeding, which not only leads to waste of raw materials, but also seriously pollutes the environment and hygiene, thereby causing food safety hazards. In addition, manual stuffing also faces many problems, such as large labor intensity and high labor intensity.

[0004] The main reasons why the production process of steamed dumplings cannot get rid of manual stuffing are two-fold: first, the traditional stuffing method is difficult to effectively cooperate with modern automated equipment; second, the two commonly used stuffing methods, auger stuffing and pipe pump pressure stuffing, will cause a certain degree of extrusion to the stuffing of steamed dumplings. Since the steamed dumplings contain glutinous rice after being soaked, it is easily broken when extruded, thereby affecting the final taste.

[0005] With the increasing control requirements of enterprises on labor intensity and raw material waste, as well as the increasing emphasis on cost control and production efficiency, it is particularly urgent to develop a precise and efficient automatic stuffing process. This not only helps to improve the quality and safety of steamed dumpling production, but also effectively improves the production efficiency of enterprises, reduces production costs, and further enhances the competitiveness of enterprises in the market.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment one of a dumpling automatic stuffing device of the present application: A dumpling automatic stuffing device, comprising a horizontally extending stuffing platform 100, the stuffing platform 100 is supported by a supporting leg and floats above the dumpling machine 200, a plurality of dumpling machines 200 are arranged along the stuffing platform 100, and the automatic stuffing car 300 travels along the stuffing platform 100 to meet the stuffing needs of different dumpling machines 200.

[0025] The one end of the stuffing platform 100 is a stuffing end, and the other end is a device cleaning end. The stuffing end is connected with the stuffing lifting mechanism 400, and the device cleaning end is connected with the cleaning platform 500. The stuffing lifting mechanism 400 comprises a stuffing lifting and overturning machine 401 and a stuffing trolley 402 which is lifted along the lifting mechanism. When the stuffing trolley 402 is lowered to the position, the stuffing trolley 402 is connected with the stuffing making mechanism to receive the made stuffing. When the stuffing trolley 402 is lifted to the position, the stuffing trolley 402 is overturned to pour the stuffing in the trolley into the automatic stuffing vehicle 300. The cleaning platform 500 is connected with the sewage device 600, and the sewage device 600 is used to discharge the residual water after cleaning. Specifically, a through hole is arranged on the cleaning platform 500, the through hole is connected with the inlet of the sewage device 600, and when the automatic stuffing vehicle 300 is moved to the device cleaning end, the discharge port of the automatic stuffing vehicle 300 is located at the through hole. The cleaning water in the automatic stuffing vehicle 300 and the residual objects after cleaning can flow into the sewage device 600 through the discharge port.

[0026] The detection component group 800 is arranged on the stuffing platform 100, and the detection component group 800 comprises a plurality of groups of sensors. The automatic stuffing device for the steamed dumplings further comprises a controller. The controller controls the movement of the automatic stuffing vehicle 300 according to the information transmitted by the detection component group 800, the information transmitted by the hopper stuffing position sensor 204 and the information transmitted by the detection sensor 6, so as to ensure that the automatic stuffing is smoothly performed.

[0027] In the embodiment, a plurality of steamed dumpling machines 200 are arranged on the same side of the stuffing platform 100 and are arranged at intervals along the extension direction of the stuffing platform 100. The detection component group 800 comprises a deceleration sensor 801 and a position sensor 802 which are arranged corresponding to each steamed dumpling machine 200. When the automatic stuffing vehicle 300 runs to the deceleration sensor 801, the speed of the automatic stuffing vehicle 300 is slowed to a set value. When the automatic stuffing vehicle 300 runs to the position sensor 802, the automatic stuffing vehicle 300 is stopped at a position which can be connected with the corresponding steamed dumpling machine 200 for stuffing.

[0028] The detection component group 800 further comprises an origin detection sensor 803 which is arranged at the stuffing end. The origin detection sensor 803 is used to determine whether the automatic stuffing vehicle 300 has run to the stuffing end. Only when the automatic stuffing vehicle 300 has run to the stuffing end, the stuffing trolley 402 is controlled to be overturned to pour the stuffing.

[0029] The automatic stuffing vehicle 300 frequently moves between different steamed dumpling machines 200, and a small amount of stuffing is sent to the stuffing buffer slide 202 of the different steamed dumpling machines 200 for many times, so that the stuffing in the stuffing buffer slide 202 can be used up within 15 minutes, and the loss of water in the stuffing is avoided to affect the taste of the finished product.

[0030] The steamed dumpling machine 200 comprises a body 201, a stuffing buffer chute 202 and a steamed dumpling machine hopper 203 are fixed above the body 201, the steamed dumpling machine 200 further comprises a hopper stuffing position sensor 204, the stuffing buffer chute 202 is used for docking the automatic stuffing vehicle 300 to receive stuffing, the steamed dumpling machine hopper 203 is used for storing stuffing, and the stuffing buffer chute 202 can also temporarily store part of the stuffing as a backup storage. The hopper stuffing position sensor 204 is used for detecting the stuffing height, and when it detects that the stuffing reaches the set height, the automatic stuffing vehicle 300 is stopped from stuffing by the controller, so as to avoid the excessive stuffing in the stuffing buffer chute 202 from falling off.

[0031] The automatic stuffing vehicle 300 comprises a stuffing vehicle hopper 1 with an open upper end for pouring stuffing, and an auger 2 is arranged in the stuffing vehicle hopper 1 along the length direction of the stuffing vehicle hopper 1. The auger 2 is used for conveying the stuffing in the stuffing vehicle hopper 1 out of a discharge port 11 at the front end, and a guide port 12 is arranged at the discharge port 11 to guide the conveying of the stuffing. A scattering frame 3 is further arranged above the auger 2 in the stuffing vehicle hopper 1, and the scattering frame 3 comprises a scattering shaft 31 and a plurality of needle-shaped scattering rods 32 fixed to the scattering shaft 31. The needle-shaped scattering rods 32 extend along the radial direction of the scattering shaft 31, and the arrangement directions of the plurality of needle-shaped scattering rods 32 are staggered. The scattering frame 3 is used for preventing the upper layer of stuffing from being hollowed out, so as to ensure that the stuffing can be smoothly conveyed out of the auger 2. In the embodiment, the scattering frame 3 is controlled by an independent motor.

[0032] The auger 2 has a two-section structure, comprising a driving auger 21 and a driven auger 22. The driving auger 21 comprises a driving shaft 211 and a driving paddle 212, wherein the driving paddle 212 is arranged on the front half of the driving shaft 211, and the driven auger 22 has a sleeve structure and is sleeved on the rear half of the driving shaft 211. The driving auger 21 is driven to rotate by an auger driving motor 7, and a clutch transmission mechanism 4 is arranged between the front end of the driven auger 22 and the driving auger 21. The clutch transmission mechanism 4 is used for switching the power transmission state of the driving auger 21 to the driven auger 22, so as to finally realize the purpose of rotating the driven auger 22 only when feeding is needed.

[0033] Two clamping holes 213 are arranged at the rear end of the driving paddle 212 in the circumferential direction, and two clamping protrusions 221 are correspondingly arranged at the front end of the driven auger 22. The shape of the clamping protrusions 221 is consistent with the shape of the clamping holes 213, and the clamping protrusions 221 will be disengaged from or engaged with the clamping holes 213 when the driven auger 22 translates along the driving shaft 211.

[0034] The clutch transmission mechanism 4 comprises a clutch driving element 41 and a driving rod 42. The middle part of the driving rod 42 is hinged to the inner wall of the rear side of the stuffing hopper 1, the lower end is a free overhanging end, and the upper end is hinged to the linear displacement output end of the clutch driving element 41, and the driving rod 42 forms a lever structure with the middle part as the fulcrum. When the linear displacement output end of the clutch driving element 41 protrudes forward, the overhanging end of the driving rod 42 moves backward, the driven auger 22 is reset under the action of the stuffing resistance, the power transmission between the driving auger 21 and the driven auger 22 is disconnected, and the driven auger 22 idles relative to the driving shaft 211. When the linear displacement output end of the clutch driving element 41 retracts backward, the overhanging end of the driving rod 42 moves forward, pushing the driven auger 22 forward, so that the clamping protrusion 221 engages with the clamping opening 213, and the power transmission is realized.

[0035] It should be emphasized that, in order to avoid dispersing the stuffing, the rotating speed of the driving auger 21 is relatively slow, so when the driving rod 42 pushes the driven auger 22 to move forward to approach the driving auger 21, there may be a situation that the clamping protrusion 221 and the clamping opening 213 do not correspond in the circumferential direction, but as the driving auger 21 continues to rotate, when the two are circumferentially aligned, the clamping protrusion 221 will smoothly engage with the clamping opening 213. Because the rotating speed of the driving auger 21 is relatively slow, this process will not cause a large rigid impact to damage the clamping protrusion 221.

[0036] The overhanging end of the driving rod 42 is forked, the gap between the two prongs is a gap for the driven auger 22, and the lower end of the overhanging end is provided with a rotatable roller 421, the front end of the roller 421 protrudes beyond the front end of the prong, so as to push the driven auger 22 forward by the roller 421. The roller 421 protects the contact part of the two. The dispersing frame 3 is located directly above the auger 2, and a gap hole 422 is formed in the driving rod 42 to avoid the dispersing frame 3 when the driving rod 42 moves.

[0037] The auger driving motor 5 is fixed at the rear of the stuffing hopper 1, and is used to directly drive the driving shaft 211 to rotate or drive the driving shaft 211 to rotate after being decelerated. In other embodiments, the output power of the auger driving motor 5 can also be transmitted to the dispersing frame 3 to provide power for its rotation.

[0038] The pitch of the paddle of the driving auger 21 is greater than the pitch of the paddle of the driven auger 22, and when transporting the stuffing, the driving auger 21 is started first to send the material in front of the stuffing hopper out through the discharge port 11. When the height of the stuffing at the front end of the stuffing hopper 1 is lower than the set value, the clutch transmission mechanism 4 controls the driven auger 22 to engage with the driving auger 21, the power of the driving auger 21 is transmitted to the driven auger 22, and the driven auger 22 rotates to continue to transport the material behind the stuffing hopper forward.

[0039] In this embodiment, the diameter of the driving shaft 211 is 40 mm, the pitch of the driving auger 21 is 150 mm, and the outer diameter is 260 mm; the pitch of the driven auger 22 is 100 mm, and the outer diameter is 260 mm.

[0040] It is emphasized that, in order to avoid the stuffing in the stuffing hopper 1 from spilling out, the size of the discharge port 11 is slightly smaller than the outer diameter of the driving auger 21. Therefore, during the process of sending out the stuffing through the discharge port 11, the stuffing will inevitably be extruded. In the present application, the driven auger 22 with a smaller pitch can form stronger gripping force and sealing performance, so as to ensure that the stuffing in the stuffing hopper can be stably and continuously gripped, prevent the stuffing from backflowing, and at the same time, establish sufficient pushing pressure, so as to successfully transport the viscous stuffing mixed with rice grains forward. The pitch of the front driving auger 21 is larger, and in the case that the driving shaft 211 rotates one circle, the distance that the driving auger 21 pushes the stuffing forward is greater than the distance that the driven auger 22 pushes the stuffing forward. In combination with the mode that the driving auger 21 is operated first and the driven auger 22 is connected later, the extrusion speed and compression ratio of the material in front of the outlet can be effectively reduced, the pressure and the shear force at the outlet are avoided from being too high, so as to greatly reduce the extrusion and breakage of the rice grains, and ensure the looseness of the stuffing and the integrity of the rice grains. Through the variable-pitch design of the front large and rear small, and the form that the material is sent out first at the front and then supplemented at the rear, the purpose of stable high-pressure sealing transportation at the rear end and low-pressure gentle release at the front end is achieved, and the contradiction between transportation and shape preservation is perfectly solved.

[0041] A detection sensor 6 is installed at the front upper side of the stuffing hopper 1, and the detection sensor 6 is used to detect the height of the stuffing in the stuffing hopper 1. When the height of the stuffing in the stuffing hopper 1 is lower than the minimum value, the stuffing hopper returns to the stuffing supply end to be filled with stuffing. When the height of the stuffing in the stuffing hopper 1 reaches the maximum value, the lifting mechanism 400 stops supplying the stuffing.

[0042] Embodiment two: The difference between embodiment two and embodiment one is that a reset member for driving the driven auger 22 to reset rearward is arranged between the driven auger 22 and the rear sidewall of the stuffing hopper 1, and the reset member is a tension spring, and the two ends of the tension spring are respectively abutted against the rear sidewall of the driven auger 22 and the rear sidewall of the stuffing hopper 1.

[0043] An embodiment of a stuffing process for the shumai according to the present application: The process for adding stuffing to the steamed dumplings according to the present application is based on the embodiment of the automatic stuffing adding device for the steamed dumplings, and the difference from the common process for adding stuffing to the steamed dumplings is that the automatic stuffing adding vehicle 300 moves along the overhead track on the stuffing adding platform 100 between the multiple steamed dumpling machines 200, and adds stuffing to the steamed dumpling machine in need of adding stuffing under the control of the controller, and the amount of stuffing added each time does not exceed the amount of stuffing required for the steamed dumpling machine 100 to produce in 15 minutes; and the prepared stuffing is vertically lifted to the height of the stuffing adding platform 100 by the stuffing supplying lifting mechanism 400 and is fed into the automatic stuffing adding vehicle 300.

[0044] When the automatic stuffing adding vehicle 300 moves to the steamed dumpling machine 200 in need of adding stuffing, it first moves at high speed to approach the target steamed dumpling machine 200 and then moves at low speed to the target position.

[0045] It is apparent to those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the present application should be defined by the appended claims rather than the above description, and it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
