Foodstuff filling supply device and method

Abstract

The application provides a food stuffing supply device and method, relates to the field of food equipment, and aims at the problem of mixed taste caused by the mixing of multiple stuffings in a common dough mold. The dough forming bin forms a guide channel through which a guide pipe passes and a dough cavity around the outside of the guide channel. The stuffing bin can be adjusted in position to switch the stuffing. The guide pipe of each stuffing bin is independent of each other. During the process of stuffing delivery, there is no common channel, thereby avoiding the problem of mixing and mixed taste. For the problem of uneven supply and damaged taste caused by the poor flowability and poor extrusion resistance of the stuffing, the application uses the structure of the auger and the stuffing bin to ensure the continuous and stable supply of the stuffing and reduce the damage to the stuffing. The problem of loss of fresh characteristics caused by the extrusion damage of the stuffing due to the narrow space is avoided, and the taste and flavor quality of the food are ensured.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of food equipment, in particular to a food stuffing supply device and method. BACKGROUND

[0002] The current stuffing equipment mostly adopts the mode of forming a dough tube, filling the inside with stuffing, and finally using a mold to press and cut the dough tube. The stuffing supply mechanism under this mode is generally equipped with a single bin and two bins. The two bins need to be disassembled and cleaned for a long time to avoid mixing between the stuffings. If not cleaned thoroughly, it will also affect the taste of the steamed buns or dumplings. In addition, the steamed bun machine and dumpling machine equipment have high requirements for the operators and the operation is complicated, and it takes a long time to change the stuffing.

[0003] A steamed bun machine is disclosed in Chinese patent (publication number: CN 220734222 U), which uses a rotating disc to drive multiple spiral stuffing conveying parts to rotate. By changing the positions of the stuffing hopper and the dough mold, the stuffing output pipe is connected with the dough mold. The stuffing is output from the stuffing output pipe and then enters the stuffing core pipe of the dough mold. The stuffing is put into the formed dough tube through the stuffing core pipe for stuffing. The rotating structure increases the available types of stuffing and switches them through rotation to meet the stuffing requirements of different stuffings. However, the different stuffing hoppers need to be put through the stuffing core pipe after being output through the stuffing output pipe. The stuffing core pipe is a common section, which still causes mixing between different stuffings remaining on the stuffing core pipe, resulting in mixed taste of the food after stuffing, which is difficult to meet the stuffing requirements. In addition, the current stuffing assembly supplies stuffing by using an extrusion feeding method, which causes extrusion damage to the food materials in the vegetarian stuffing, resulting in water leakage and fragmentation of the food materials, affecting the quality of the stuffing. There is also a situation of interruption and discontinuity of the supply of stuffing. In the conventional scheme of adding materials such as skin jelly and batter to improve the flowability of the vegetarian stuffing, the mixed materials also change the taste and texture of the stuffing, which is difficult to meet the texture and taste requirements of the food at the time of serving.

DETAILED DESCRIPTION

[0037] Embodiment 1

[0038] In a typical embodiment of the present application, as shown in Figures 1-6 a foodstuff filling supplying device is provided.

[0039] The current filling conveying channel of the filling equipment has a shared section. The residual filling in the shared section is mixed with the subsequent filling, which affects the taste and quality of the food after filling. Based on this, the present embodiment provides a foodstuff filling supplying device. The supply path of each stuffing chamber 103 is independently arranged to avoid mixing with other stuffing chambers 103 during the filling conveying process. The filling output by each stuffing chamber 103 can be directly discharged into the wrapper cavity output by the wrapper forming chamber 7, and the filling is isolated to avoid the problem of filling mixing and taste mixing, thereby ensuring the taste and quality of the output food.

[0040] Referring to Figure 1The food stuffing supply device comprises a wrapper forming bin 7, a stuffing bin assembly 1, a rotating assembly 4 and a lifting assembly 6. The wrapper forming bin 7 serves as a forming structure of the wrapper and also as a guide structure of the stuffing, which can guide the stuffing into the formed wrapper for cutting and wrapping. The stuffing bin assembly 1 is provided with a plurality of stuffing bins 103, which can accommodate different stuffings. By switching the stuffing bin 103 and the wrapper forming bin 7, different stuffings can be put into the formed wrapper. In order to switch the stuffing bin 103, the lifting assembly 6 drives the stuffing bin assembly 1 to lift, so that the stuffing bin assembly 1 can be pulled out of or inserted into the wrapper forming bin 7. The rotating assembly 4 drives the stuffing bin assembly 1 to adjust the position, so that the required stuffing bin 103 can be adjusted to the position matched with the wrapper forming bin 7, to switch and adjust the output of the stuffing.

[0041] In the embodiment, the wrapper forming bin 7 is internally formed with a wrapper cavity and a guide channel 701 separated from each other. The wrapper cavity can accommodate the dough and output under the extrusion action. The outlet of the wrapper cavity is annular, so that the dough forms a cylindrical wrapper after being output from the wrapper cavity.

[0042] The outlet of the wrapper cavity is sleeved outside the outlet of the guide channel 701. Corresponding to the guide channel 701, different stuffing bins 103 are respectively matched with corresponding guide tubes 105. The stuffing in the stuffing bin 103 is output from the end of the guide tube 105. The guide tube 105 can be inserted into the guide channel 701, and the end of the guide tube 105 extends to the outlet position of the guide channel 701, so that the stuffing can be output from the end of the guide tube 105 into the cylindrical wrapper formed by the dough without contacting the guide channel 701. The stuffing is combined with the wrapper, and then the cutting is completed by an external cutting mechanism, etc. The finished product 8 after wrapping is dropped to the tray 9.

[0043] Since the stuffing bin 103 is communicated with the guide tube 105, and different stuffing bins 103 can accommodate different stuffings, when the supplied stuffing is switched, the corresponding guide tube 105 of the replaced stuffing is pulled out of the guide channel 701 by moving the corresponding stuffing bin 103 of the previous stuffing together with the guide tube 105. The corresponding stuffing bin 103 of the next stuffing is moved to the wrapper forming bin 7, so that the corresponding guide tube 105 of the switched stuffing is reinserted into the guide channel 701 and supplies the subsequent stuffing to the wrapper cavity.

[0044] The guide tube 105 isolates the stuffing in the guide tube 105 from the guide channel 701. The guide channel 701 does not directly contact the stuffing, such as Figure 2As shown, the axial length of the guide tube 105 is greater than the axial length of the guide channel 701, and the end of the guide tube 105 away from the stuffing chamber 103 extends through the crust cavity outlet to the outside of the crust cavity. There is a gap between the lower end of the guide tube 105 and the guide channel 701 of the crust chamber former, keeping the guide tube 105 away from the inner wall of the guide channel 701 to avoid contact and friction between the guide tube 105 and the guide channel 701, and to avoid problems such as residue sticking to the wall. Multiple switching will not contact each other, ensuring that the fillings in different stuffing chambers 103 are independent.

[0045] In order to realize the smooth output of the fillings in the stuffing chamber 103, a stirring and supplying assembly 2 is configured to match the stuffing chamber 103, as shown in Figure 4 As shown, the stirring and supplying assembly 2 includes an extrusion auger 217 and a stirring shaft 215. The axis of the extrusion auger 217 coincides with the axis of the guide tube 105. The stirring shaft 215 is sleeved on the outside of the auger 217 shaft on one side of the auger 217, and extends into the stuffing chamber 103 on the other side. A scraper 218 is formed, which is spaced apart from the auger 217. There is a space between the scraper 218 and the auger 217 for the fillings to pass through, facilitating the flow of fillings and improving the output efficiency.

[0046] It should be noted that the vegetarian fillings made of leeks, carrots, zucchini, cucumbers and other vegetables are less fluid than meat fillings. When subjected to extrusion, the vegetarian fillings may be damaged and water may be released, causing the internal vegetables in the vegetarian fillings to lose a lot of water, resulting in a large amount of water and poor bulk density at the bottom of the stuffing chamber 103, increasing the difficulty of outputting the vegetarian fillings, and the damage to the vegetarian fillings may cause the taste and flavor to deteriorate. To this end, the stirring and supplying assembly 2 in the present embodiment uses a combination of an auger 217 and a stirring shaft 215. The scraper 218 formed by the auger 217 and the stirring shaft 215 is spaced apart and rotates in the opposite direction. The spaced distribution provides a space for the fillings in the stuffing chamber 103. The rotation of the auger 217 transmits the fillings downward, and the extrusion force generated during the pushing process of the auger 217 extrudes a part of the fillings out of the range of the helical blades of the auger 217, thereby releasing the extrusion force of the auger 217 on the fillings. At the same time, the scraper 218 on the stirring shaft 215 can act on the fillings adhering to the inner wall of the stuffing chamber 103 and scattered outside the auger, and form a disturbance effect opposite to the rotation direction of the auger 217, making the fillings fluffy and continuously pushing the fillings to the helical blades of the auger 217. The rotational speed of the stirring shaft 215 is less than that of the auger 217, so as to avoid secondary damage to the fillings by relatively low-speed rotation. For meat fillings, the fluidity of the meat fillings can be used to form a whipping effect, which is more conducive to the output of the meat fillings. The reverse rotating scraper 218 can push the fillings to the position of the auger 217, reducing the dead angle problem existing in the same direction rotation of the auger 217 and the stirring shaft 215, and improving the filling supply efficiency.

[0047] In order to avoid pollution of the stuffing in the stuffing chamber 103, the auger 217 is provided with an auger section without shaft extending to the end of the guide pipe 105, one end of the guide pipe 105 connected to the stuffing chamber 103 is a tapered variable diameter section 106, the scraper 218 of the stirring shaft 215 is located between the inner walls of the tapered variable diameter section 106 of the stuffing chamber 103, the scraper 218, the auger 217 and the inner walls of the tapered variable diameter section 106 are distributed at intervals to avoid direct contact between the scraper 218 and the tapered variable diameter section 106, thereby generating heat and noise problems, at the same time, a gap is left between the scraper 218 and the tapered variable diameter section 106 for the stuffing to pass through, thereby meeting the disturbance and auxiliary continuous conveying functions. The stuffing exists in the stuffing chamber 103, the guide pipe 105 at the lower end of the stuffing chamber 103 is provided with an auger section without shaft, which can support the stuffing located in the guide pipe 105, so as to ensure that the stuffing will not fall downward due to lifting or switching of the stuffing chamber 103. When the auger 217 rotates, the stuffing can fall under the drive of the auger section without shaft, and the isolation effect of the guide pipe 105 and the guide channel 701 can avoid the pollution risk in the area of the guide channel 701 in the stuffing chamber.

[0048] As shown in Figure 3 and Figure 4 , the diameter of the auger 217 located in the stuffing chamber 103 is larger than that of the auger section without shaft, the auger section 217 located in the stuffing chamber 103 is provided with an auger shaft 217, which can cooperate with the stuffing chamber 103 to provide sufficient conveying capacity with a larger diameter, meet the demand of stuffing supply, and will not affect the passability of the stuffing. The inner diameter of the guide pipe 105 corresponding to the auger section without shaft on the auger 217 is smaller than the inner diameter of the stuffing chamber 103, and the space available for passing through is smaller, so the use of the auger section without shaft can reduce the space occupied by the auger shaft 217, ensure the passing area of the stuffing in the guide pipe 105, and meet the demand of stuffing supply.

[0049] It should be pointed out that the auger section without shaft retains the spiral blades of the auger 217 and removes the inner shaft, the center part of the auger section without shaft is hollow, which reduces the occupation of space when passing through the narrow channel, effectively avoids the extrusion of the stuffing material, thereby avoiding the loss of the delicious characteristics of the stuffing due to extrusion. At the same time, the setting of the auger section without shaft in the narrow guide pipe 105 can increase the passability of the stuffing, which can effectively pass through the blades and particles of the stuffing, and has strong compatibility with the meat stuffing, which is not easy to hang the muscle fascia of the meat stuffing.

[0050] As shown in Figure 4 , the auger 217 is connected to the first driving element through the first transmission mechanism, the stirring shaft 215 is connected to the first driving element through the second transmission mechanism, the first driving element is used to drive the auger 217 and the stirring shaft 215 of the stuffing chamber 103 connected to the guide channel 701, the first transmission mechanism and the second transmission mechanism are distributed in parallel, and the upper part is provided with a protective cover 201 to isolate the stuffing.

[0051] In this embodiment, the first driving element is a first motor 209, and the first end of the auger 217 is fixed on the auger transmission shaft 216. The first transmission mechanism is a combination of the driven pulley 203, the synchronous belt 202 and the driving pulley 204. The driven pulley 203 is fixed on the auger transmission shaft 216, and is linked with the driving pulley 204 through the synchronous belt 202. The driving pulley 204 is fixed on the pulley transmission shaft 206. The pulley transmission shaft 206 is connected with the first speed reducer 208 through the driving butt joint 207, and completes power transmission. The first motor 209 is fixed with the first speed reducer 208. The second transmission mechanism includes the driving gear 205 and multi-stage transmission gears. The driving gear 205 is fixed on the pulley transmission shaft 206, and completes power transmission through the first transmission gear 210, the second transmission gear 211, the third transmission gear 212, the fourth transmission gear 213 and the stirring shaft gear 214 in sequence. The stirring shaft gear 214 is installed on the stirring shaft 215.

[0052] As shown in Figure 4 , one side of the stirring shaft 215 is a sleeve structure, and the other side extends to form a scraper 218. The sleeve structure is sleeved on the auger transmission shaft 216, and is driven by the first motor 209 in cooperation with the stirring shaft gear. The rotation of the auger 217 is independent of the rotation of the sleeve structure of the stirring shaft 215, and no mutual interference occurs during rotation, so that the two can rotate in opposite directions, and the scraper 218 rotates under the driving of the sleeve structure to disturb the stuffing in the stuffing bin 103.

[0053] The scraper 218 is formed on the outside of the stirring shaft 215 to form the inside of the stuffing bin 103, which can scrape the stuffing adhering to the inner wall of the stuffing bin 103 and collect it to the auger 217 at the central position. If the rotation direction of the scraper 218 is consistent with the rotation direction of the auger 217, the stuffing will remain between the scraper 218 and the auger 217, which is not easy to peel off.

[0054] The vegetarian stuffing of steamed buns and dumplings has the characteristics of being fluffy, poor in flowability and unable to be extruded. The common screw conveying element on the market is generally closely combined with the stuffing bin, and the conveying of the stuffing is completed by relative rotation. When the cross section of the stuffing bin 103 changes from large to small, the rotation of the screw conveying element will cause strong extrusion to the stuffing, and if the flowability of the stuffing is not strong, the transmission cannot be completed. Therefore, such structure cannot meet the conveying demand of vegetarian stuffing with poor flowability and unable to be extruded.

[0055] In this embodiment, the end of the stuffing chamber 103 connected to the guide pipe 105 is a tapered variable diameter section 106, and the scraper 218 of the stirring shaft 215 leaves a gap with the inner wall of the stuffing chamber 103. In the direction in which the diameter of the tapered variable diameter section 106 decreases, the diameter of the helical blade corresponding to the segment of the auger 217 in the tapered variable diameter section 106 gradually decreases. By reducing the diameter of the auger 217 in the variable diameter section of the stuffing chamber 103, the distance between the auger 217 and the inside of the stuffing chamber 103 is increased, and part of the space is used to accommodate the stuffing in a fluffy state. When the auger 217 rotates, the stuffing inside the helical blade of the auger 217 can be pushed downward. The extrusion force generated in this process can push the excess stuffing out of the range of the auger 217 and into the space between the auger 217 and the stuffing chamber 103, thereby solving the problem of extrusion of the stuffing in the variable diameter section of the stuffing chamber 103. The stuffing inside the auger 217 is transported to the guide pipe 105 in which the hollow auger 217 segment is located under the action of the helical thrust and the rotating centripetal force. The inside of the guide pipe 105 at this point is of equal diameter, and the helical thrust generated by the rotation of the hollow auger 217 segment is relatively small, and the extrusion force acting on the stuffing is unloaded in the hollow part of the auger 217. The extrusion force of the stuffing in the guide pipe 105 is reduced, and the stuffing can be transported downward under the action of the thrust of the auger 217 and its own gravity until it is discharged into the formed wrapper through the end of the guide pipe 105.

[0056] In the tapered variable diameter section 106 of the stuffing chamber 103, although the reduction of the diameter of the auger 217 solves the problem of extrusion of the stuffing, it cannot continuously supply the stuffing outside the auger 217 in the stuffing chamber 103. To this end, the stirring shaft 215 is provided in this embodiment, and the functional part on the stirring shaft 215 can act as a scraper 218 inside the stuffing chamber 103. The scraper 218 can act on the stuffing adhering to the inner wall of the tapered variable diameter section 106 of the stuffing chamber 103, and the scraper 218 rotates in the opposite direction at a relatively low speed relative to the auger 217. The relatively fast rotation of the auger 217 is to meet the flow demand of the supply of stuffing, and the centrifugal force generated by the fast rotation reduces the mutual adhesion between the stuffing and the auger 217, facilitating the application of the pushing force. The scraper 218 of the stirring shaft 215 cooperates with the inner wall of the stuffing chamber 103 to rotate at a relatively low speed, reduces the extrusion and damage of the stuffing, scrapes the stuffing adhering to the inner wall of the stuffing chamber 103 to the auger 217 at the central position, and completes the continuous supply of the stuffing.

[0057] The reverse slow rotation of the scraper 218 of the stirring shaft 215 can continuously supply the stuffing outside the auger 217 to the inside of the auger 217, and complete the continuous supply of the stuffing. The variable diameter auger 217 can transport the stuffing downward by the helical thrust, and at the same time solve the problem of extrusion of the stuffing during transportation.

[0058] As Figure 3As shown, multiple filling bins 103 are arranged in a circular array and maintained in relative position by flanges. The output end of the lifting assembly 6 is connected to the flanges via a floating joint. The floating joint transmits the lifting and lowering between the lifting assembly 6 and the filling bin assembly 1 and isolates rotation. In this embodiment, the upper flange 102 and the lower flange 104 of the filling bins 103 in the filling bin assembly 1 together fix six filling bins 103, and the cover plate 101 of the filling bins 103 is fixed on the filling bins 103.

[0059] like Figure 5 As shown, the rotating component 4 is connected to the filling container component 1. When the filling container component 1 is driven by the rotating component 4, the relative position of the filling container 103 and the dough forming container 7 is adjusted to change the filling container 103 corresponding to the guide tube 105 matched by the guide channel 701. The output end of the rotating component 4 cooperates with the turntable through a gear transmission mechanism. The filling container component 1 is installed on the turntable. The gear transmission mechanism includes a rotary drive gear connected to the output end of the rotating component 4 and a rotary driven gear provided on the turntable. The turntable is driven by the lifting component 6 following the filling container component 1, thereby causing the rotary drive gear and the rotary driven gear to mesh or disengage.
