Description

Technical Field

[0001] The present invention relates to the technical field of heating and forming of soybean cakes, and specifically to a heating and forming method for soybean cake production. Background Technique

[0002] For soft - skinned mung bean cakes, usually, the peeled mung beans are washed and soaked overnight. The soaked mung beans are steamed over high heat for 40 minutes until cooked and mushy. After the steamed mung beans are added with fine granulated sugar, corn oil, etc. and stirred until in a flocculent state, they are kneaded into a smooth dough. The mung bean dough is divided into multiple small segments, each weighing about 20 - 30 grams, and kneaded into small balls for standby. Secondly, it is also necessary to make the water - oil skin: mix medium - gluten flour, yeast, corn oil, fine granulated sugar and water, stir until in a flocculent state, and then knead into a smooth dough. Let it proof for 30 minutes until the dough relaxes. Wrap the mung bean cakes. Divide the proofed water - oil skin dough into small dough pieces equal in quantity to the mung bean fillings. Take a small water - oil skin dough piece, roll it into a round thin sheet, wrap a small mung bean filling ball, seal it tightly, and gently press it into a cake shape. Then, the soybean cake embryos are put into an oven for heating and forming.

[0003] When the existing soybean cakes are heated and formed, their outer surfaces usually expand into a quasi - cylindrical shape, and their outer contours are irregular approximate circles, which reduces their aesthetic appearance in commercial production. Moreover, when multiple soybean cakes are placed on a tray, the bottom contacts the tray, and the rest is heated by hot air. During the heating process, the heating is uneven, resulting in different degrees of doneness in different parts after heating, affecting the taste. And when it is necessary to print words or patterns on the soybean cakes to increase their beauty and commercial value, only edible pigments, etc. can be dotted on the soybean cakes after heating for supplementation. The filled - in patterns do not perfectly fit the soybean cakes themselves, reducing the commercial value when the soybean cakes are sold.

[0004] Therefore, we propose a heating and forming method for soybean cake production to solve the problems encountered above. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a heating and forming method for soybean cake production to solve the problems raised in the above - mentioned background technique.

[0006] The purpose of the present invention can be achieved through the following technical solutions: including the following steps:

[0007] Step 1: During the production of soybean cakes, first, the soybean cake embryos need to be accurately placed on the cake trays and ensure that they are aligned with the positions of the soybean cake positioning grooves. After placing the soybean cake embryos, next, the mold rack is inverted on the tabletop. According to the production requirements, select a suitable outer mold, and according to the need for printing, sequentially combine the corresponding inner mold with the selected outer mold by means of threaded connection, ensuring that the number of connected inner and outer molds matches the number of soybean cake embryos produced this time. Subsequently, insert the outer mold with the connected inner mold into the mold rack, ensuring that the card slots in the outer mold can be embedded in the snap rings outside the corresponding inner rings. Repeat the above steps until all outer molds are correctly installed on the mold rack.

[0008] Step 2: When placing the soybean cake embryos, first, open the oven door, then move the cake tray containing the soybean cake embryos together with the tray into the oven. Align the slots in the positioning ring frame on the tray with all the top material racks in one of the top trays, and then place the tray downward so that the top material racks can be inserted into the support ring frame under the cake tray above it. As the tray descends, the top material racks separate from the tray. At the same time, during the ascending process of the cake tray, it will push the pressing frames on both sides outward, causing them to rotate outward and driving the torsion springs to deform. When the cake tray no longer contacts the pressing frames, the pressing frames deflect reversely under the elastic force of the torsion springs until they abut against the inner side of the tray.

[0009] Step 3: Move the mold rack with the installed outer mold into the oven and place it above the lifted cake tray. Ensure that the vertical frame is aligned with the through slot on the cake tray and insert it downward until the positioning convex ring abuts against the upper surface of the cake tray. Then, horizontally push the clamping rods from the front and back sides into the notches of the same-side vertical frames under the lifted cake tray. After completing these steps, close the oven door inward, start the oven, and set appropriate heating temperature and time to heat and form the soybean cake embryos already placed in the oven.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By providing the ejector assembly and the cake pan fixing assembly, it can be ensured that the soybean cake can protrude out of the tray as a whole during the heating process. This not only enables the bottom of the soybean cake to fully contact with the hot air, but also significantly increases the contact area. This design helps the soybean cake to be heated more evenly, so that the ripeness of the whole soybean cake is consistent, ensuring the taste during consumption; in addition, when the tray is placed in the oven, the soybean cake embryo can rise naturally without any additional operation. This not only simplifies the whole operation process, but also when the tray is placed normally, the cake pan can remain stable and will not automatically detach, which will not affect the operation of placing the soybean cake embryo, making the whole preparation and feeding process very convenient.

[0022] 2. By providing the heating and forming die assembly and the die assembly, the shape of the soybean cake can be effectively controlled. This design ensures that the soybean cake will not over-expand or deform during the baking process, thus guaranteeing the appearance beauty of the baked soybean cake; in addition, the design of the die holder allows for overall disassembly and installation, which greatly simplifies the disassembly and assembly operations, thereby improving production efficiency; finally, an independently installable printing structure is also designed inside the outer die. This structure can also be independently disassembled and installed, which enables grooves with patterns to be formed on the surface of the soybean cake during the forming process, thus improving the distinguishability of the formed soybean cake. This design not only increases the beauty of the soybean cake, but also helps to improve the commercial value of the soybean cake, making it more competitive when sold.

Detailed implementation manners

[0035] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 - Figure 10As shown in the figure, a heating and forming method for soybean cake production is realized based on a heating and forming device for soybean cake production. The device includes an oven 1. Inside the oven 1, a number of grills 11 are arranged from top to bottom. On the grill 11, a top feeding component is arranged. The top feeding component includes a chassis 20 placed on the grill 11. On the chassis 20, a top plate 21 is placed. On the top of the top plate 21, top feeding racks 22 are distributed in sequence from left to right. Above the grill 11 and above the top plate 21, a tray 23 is also placed. Inside the tray 23, positioning ring frames 24 are fixedly connected in sequence from left to right. The top feeding rack 22 is slidably connected inside the adjacent positioning ring frame 24. Above the tray 23, a cake plate 25 is also arranged. At the bottom of the cake plate 25, supporting ring frames 26 are fixedly connected in sequence from left to right. The top end of the top feeding rack 22 is inserted inside the adjacent supporting ring frame 26;

[0037] It should be noted that the design of the chassis 20 is to accurately position the top plate 21, ensuring that during the production of soybean cakes, the chassis 20 is tightly connected to the grill 11 and will not become detached. The function of the top plate 21 is to fix multiple top feeding racks 22. After the tray 23 is placed inside the oven 1, the top feeding rack 22 can quickly lift the cake plate 25, reducing additional operations, thereby ensuring production efficiency. The positioning ring frame 24 further positions and guides the top feeding rack 22. The supporting ring frame 26 limits the contact part between the top feeding rack 22 and the cake plate 25. In this way, after the cake plate 25 is lifted, the cake plate 25 can receive a stable supporting force, avoiding tilting or instability during the production process, thus ensuring the smoothness of the entire production process and the quality of the product. By setting the top feeding component, it can be ensured that during the heating process, the soybean cake can protrude entirely outside the tray 23. This not only enables the bottom of the soybean cake to fully contact the hot air but also significantly increases the contact area. This design helps the soybean cake to be heated more evenly, so that the ripeness of the entire soybean cake remains consistent, ensuring the taste when eaten; in addition, after the tray 23 is placed in the oven 1, the soybean cake embryo can rise naturally without any additional operations, simplifying the entire operation process.

[0038] A hot forming die assembly, the hot forming die assembly includes placing grooves 30 opened on a cake pan 25, and they are equally spaced from left to right. Bean cake positioning grooves 31 are opened on the placing grooves 30. Through grooves 32 are respectively opened on the front and rear sides of the top of the cake pan 25, and they are equally spaced from left to right. A die holder 33 is further provided on the cake pan 25. Horizontal frames 34 are respectively fixedly connected to the front and rear sides of the die holder 33. Vertical frames 35 are fixedly connected to the lower parts of the horizontal frames 34. Positioning convex rings 36 are respectively fixedly connected to the upper parts of the left and right sides of the vertical frames 35. Notches 37 are respectively opened on the lower parts of the left and right sides of the vertical frames 35. Clamping rods 38 are respectively provided on the lower parts of the front and rear sides of the same die holder 33. The clamping rods 38 are slidably connected between the inner sides of the notches 37 on the same side. The vertical frames 35 are slidably connected in the adjacent through grooves 32. The positioning convex rings 36 are abutted against the top of the cake pan 25. A number of circular holes 331 are opened on the die holder 33. An inner ring 332 is fixedly connected to the bottom of the die holder 33 and located outside the circular holes 331. Snap rings 333 are respectively embedded above and below the outer ring 332. It further includes a die assembly. The die assembly includes an outer die 40 arranged outside the inner ring 332. Two clamping grooves 41 are opened on the upper side inside the outer die 40. An inner top plate 42 is fixedly connected to the middle inside the outer die 40. A threaded groove 43 is opened in the middle of the inner top plate 42. An inner die 44 is threadedly connected in the threaded groove 43. A printing frame 45 is fixedly connected to the bottom of the inner die 44. A number of vent holes 46 are respectively opened on the inner top plate 42 and the outer lower side of the outer die 40 in a circular distribution.

[0039] It should be noted that the placement groove 30 is designed to distinguish the processing surface and ensure the accurate position of the soybean cake during the processing. The soybean cake positioning groove 31 further helps to distinguish and accurately position the placement position of the soybean cake, and at the same time prevents the soybean cake embryos from being too close to each other without restriction, so as to avoid the problem of sticking to each other during the heating and expansion process. The through groove 32 is designed to facilitate the passage of the vertical frame 35, and the positioning convex ring 36 is used to limit the maximum descending height of the vertical frame 35 in the through groove 32, ensuring that the mold frame 33 can be supported at a fixed height on the cake tray 25. The horizontal frame 34 is designed to facilitate the fixation of the vertical frame 35, and the notch 37 is convenient for clamping the clamping rod 38. After the mold frame 33 is integrally supported on the cake tray 25, by clamping the clamping rod 38 into the notch 37, the top surface of the clamping rod 38 fits into the lower surface of the cake tray 25 and slides into multiple notches 37 on the same side to prevent the soybean cake embryo from expanding and lifting the mold frame 33 during the heating process, thus ensuring that the soybean cake embryo can be effectively constrained and restricted. The round hole 331 is designed to allow the air flow to pass through, and the inner ring 332 is used to install the snap ring 333. The snap ring 333 cooperates with the card slot 41 on the outer mold 40 to facilitate the disassembly and installation of the outer mold 40 and the mold frame 33. The inner top plate 42 is used to limit the height that the soybean cake can be formed, and a protrusion is provided in the middle of its top to leave room for the processing of the threaded groove 43. By connecting the inner mold 44 and the outer mold 40 through thread fitting, the printing frame 45 on the inner mold 44 can be conveniently disassembled and replaced, further increasing the adaptability range of the device so that it can adapt to the needs of soybean cakes with different printing requirements. The vent hole 46 is designed to allow hot air to enter and exit, facilitating the heating and forming of the soybean cake. By setting the heating and forming mold assembly and the mold assembly, the shape of the soybean cake can be effectively controlled. This design ensures that the soybean cake will not over-expand or deform during the baking process, thus guaranteeing the aesthetic appearance of the soybean cake after baking; in addition, the design of the mold frame 33 allows for overall disassembly or installation, which greatly simplifies the disassembly and assembly operations, thereby improving the production efficiency; finally, an independently installable printing structure is also designed inside the outer mold 40, and this structure can also be independently disassembled and installed, which enables grooves with patterns to be formed on the surface of the soybean cake during the forming process, thus improving the differentiation degree of the soybean cake after forming. This design not only increases the aesthetic appearance of the soybean cake but also is beneficial to improving the commercial value of the soybean cake, making it more competitive when sold.

[0040] It further includes a cake pan fixing assembly. The cake pan fixing assembly includes brackets 231 fixedly connected to the left and right sides of the tray 23. A fixed shaft 232 is fixedly connected between the inner walls on the front and rear sides of the brackets 231. Pressing frames 233 are respectively rotatably connected to the front and rear sides outside the fixed shaft 232. A torsion spring 234 is also sleeved on the outer end of the fixed shaft 232. The two ends of the torsion spring 234 are respectively fixedly connected to the adjacent fixed shaft 232 and the outside of the pressing frame 233. The same pull handle 235 is fixedly connected between the two pressing frames 233.

[0041] It should be noted that the design of the fixed shaft 232 is to provide a stable rotation center point for the pressing frame 233 to ensure that it can rotate smoothly. The function of the torsion spring 234 is to apply a necessary rotational force to the pressing frame 233, so as to ensure that the pressing frame 233 can effectively press the cake pan 25 to ensure its stability. The pull handle 235 connects the two pressing frames 233 on the same side. This design greatly simplifies the operation process. The user only needs to pull the pull handle 235 to easily drive the two pressing frames 233 to rotate synchronously, which not only improves the convenience of operation, but also makes the whole process more efficient. The function of the entire cake pan fixing assembly is that when the cake pan 25 is placed inside the tray 23, it can firmly press the cake pan 25 inside the tray 23 to prevent the cake pan from bouncing or shifting due to bumps during transportation, ensuring that the soybean cake embryos or soybean cakes on the cake pan 25 can be kept in a fixed position, thus providing higher reliability during use.

[0042] A positioning groove 201 is provided in the middle of the chassis 20. Limit bumps 202 are respectively fixedly connected to the four corners of the bottom of the chassis 20. The original intention of the design of the positioning groove 201 is to ensure that the top plate 21 can be accurately positioned on the chassis 20, thereby preventing unnecessary movement of the top plate on the chassis during use. Through this positioning mechanism, the stability and safety of the top plate 21 can be effectively maintained. At the same time, the function of the limit bumps 202 is to cooperate with specific gaps on the grill 11 to prevent the chassis 20 from sliding or shifting on the grill 11. Through this double guarantee measure, that is, the coordinated work of the positioning groove 201 and the limit bumps 202, the stability of the entire device during placement and use has been greatly improved.

[0043] An annular positioning frame 236 is fixedly connected inside the tray 23. The height of the annular positioning frame 236 is not less than the sum of the heights of the positioning ring frame 24, the support ring frame 26 and the cake pan 25. By limiting the height of the annular positioning frame 236, it is convenient that after the cake pan 25 is placed in the tray 23, the four sides of the cake pan 25 will be restricted by the annular positioning frame 236 to avoid the movement of the cake pan 25 in the tray 23 and reduce operation errors.

[0044] An air vent groove is annularly formed on the bean cake positioning groove 31. The position and quantity of the bean cake positioning groove 31 are consistent with those of the round holes 331. The air vent groove facilitates the passage of hot air flow, facilitating the heating of the bottom of the bean cake embryo and being conducive to maintaining the overall heat uniformity of the bean cake embryo.

[0045] Empty grooves 334 are equidistantly formed on the mold frame 33 from left to right. Grooves are respectively formed on the front and rear sides of the mold frame 33 and are equidistantly distributed from left to right. The empty grooves 334 and the grooves are used to reduce the mass and material consumption and lower the manufacturing cost.

[0046] The cross-section and size of the clamping groove 41 are consistent with those of the part of the clamping ring 333 protruding from the inner ring 332. The clamping ring 333 is made of silica gel material. The clamping ring 333 is made of food-grade heat-resistant silica gel material. The selection of this material enables the clamping ring 333 to ensure elastic deformation during use and enables it to be heated by the oven 1 when the clamping ring 333 and the bean cake embryo are put into the oven 1 for heating together. This embedding mechanism between the clamping ring 333 and the clamping groove 41 improves the operation convenience because it not only ensures the tight fit between the outer mold 40 and the inner ring 332 but also greatly simplifies the operation processes of disassembly and installation.

[0047] The front view cross-section of the pressing frame 233 is arc-shaped. A weight-reducing groove is formed on the pressing frame 233. Through the design of the weight-reducing groove, the weight of the pressing frame 233 can be further reduced, thereby effectively reducing the cost expenditure during its manufacturing process. This design not only contributes to economy but also enables the pressing frame 233 to avoid being adversely affected by the annular positioning frame 236 by adopting an arc-shaped structure. Such improvement enables the pressing frame 233 to provide more stable and reliable support when fixing the cake tray 25.

[0048] During the production process of the present invention, first, the bean cake embryo needs to be accurately placed on the cake tray 25 and ensured to be aligned with the position of the bean cake positioning groove 31. After the placement of the bean cake embryo is completed, next, the mold frame 33 is inverted on the tabletop. According to the production requirements, a suitable outer mold 40 is selected, and according to the printing needs, the corresponding inner mold 44 and the selected outer mold 40 are sequentially combined by means of threaded connection to ensure that the quantity of the connected inner mold 44 and outer mold 40 matches the quantity of the bean cake embryos produced this time. Subsequently, the outer mold 40 with the inner mold 44 already connected is inserted into the mold frame 33 to ensure that the clamping groove 41 in the outer mold 40 can be embedded into the clamping ring 333 outside the corresponding inner ring 332. The above steps are repeated until all the outer molds 40 are correctly installed on the mold frame 33.

[0049] Step 2, when putting in the bean cake embryo, first you need to open the door of the oven 1, then move the cake plate 25 containing the bean cake embryo together with the tray 23 into the oven 1, align the slots in the positioning ring frame 24 on the tray 23 with all the top material racks 22 in one of the top plates 21, and then place the tray 23 downward so that the top material rack 22 can be inserted into the supporting ring frame 26 under the cake plate 25 above it. As the tray 23 descends, the top material rack 22 separates from the tray 23. At the same time, the cake plate 25 pushes the pressing frame 233 to both sides during the rising process, causing it to rotate outward and drive the torsion spring 234 to deform. When the cake plate 25 is no longer in contact with the pressing frame 233, the pressing frame 233 deflects in the opposite direction under the elastic force of the torsion spring 234 until it abuts against the inner side of the tray 23.

[0050] Step 3: Move the mold frame 33 with the outer mold 40 installed into the oven 1 and place it above the raised cake plate 25, ensure that the vertical frame 35 is aligned with the through groove 32 on the cake plate 25 and insert it downward until the positioning protruding ring 36 abuts against the upper surface of the cake plate 25, and then push the clamping rod 38 horizontally from the front and back sides into the missing groove 37 of the vertical frame 35 on the same side below the raised cake plate 25. After completing these steps, close the oven door inward, start the oven 1, and set the appropriate heating temperature and time to heat and shape the bean cake embryo that has been placed in the oven 1.

Obviously, many modifications and changes can be made according to the content of this specification.
