Description

Technical Field

[0001] The present invention belongs to the technical field of gummy candy preparation, and particularly relates to a preparation device and a preparation method for sandwich-type functional gummy candies. Background Art

[0002] As a product that combines nutrients with a delicious taste, functional gummy candies are increasingly favored by consumers. However, when adding multiple nutrients to functional gummy candies, interactions between nutrients often occur, resulting in the attenuation of the efficacy of some nutrients. For example, when some vitamins are mixed with minerals, chemical reactions may occur, reducing the bioavailability of each other.

[0003] In the traditional gummy candy preparation process, the separation of the formed gummy candy from the mold is a key step. Usually, the method of ejecting with a thimble is adopted to achieve gummy candy demolding. However, this method has many drawbacks. Due to the adsorption force between the gummy candy and the inner wall of the mold, that is, the negative pressure effect, the gummy candy is extremely prone to tearing or deformation during the ejection process, especially for high-elasticity gummy candies, such as gelatin-based gummy candies, and this phenomenon is more significant. This not only affects the appearance and taste of the gummy candy but also reduces the product qualification rate.

[0004] In addition, the thimble hole is prone to residual sugar solution, providing a breeding ground for bacteria and posing potential food safety hazards. To clean the thimble hole, the mold usually needs to be disassembled, which not only increases the complexity of equipment maintenance but also prolongs the downtime of the production line, reduces production efficiency, and increases production costs.

[0005] Based on this, the present invention designs a preparation device and a preparation method for sandwich-type functional gummy candies to solve the above problems. Summary of the Invention

[0025] A method for preparing sandwich functional soft candies, the preparation method comprising the following steps:

[0026] (1) Preparation of the outer soft candy layer: Weigh gelatin and soak it in water to swell; Weigh erythritol, maltitol syrup and water, mix and heat to dissolve, add the swollen gelatin, stir evenly, heat to 85 °C and keep for 12 minutes, then add vitamin C, vitamin E, tricalcium phosphate, water-soluble dietary fiber, essence and pigment, stir evenly, and cool to 55 °C for standby;

[0027] (2) Preparation of the inner sandwich layer: Weigh gelatin and soak it in water until swollen. Weigh erythritol, mix maltitol solution with water and heat to dissolve. Add the swollen gelatin and stir evenly. Heat to 95°C and maintain for 18 minutes. Then add ferric pyrophosphate, zinc citrate, copper gluconate, and probiotics, stir evenly, and cool to 65°C for standby.

[0028] (3) Molding step: Use a mold. First, pour the cooled outer gummy layer raw material into the mold and fill it to about two-thirds of the mold capacity to initially form the outer layer. Then inject the cooled inner sandwich layer raw material into the mold to fill the mold. Cool at room temperature for 120 - 180 minutes to initially form the gummy. Then place it in an environment of 25 ± 2°C and dry for 24 ± 1 hour to completely form the gummy. After demolding, perform individual packaging with an aluminum-plastic composite film to obtain the finished product.

[0029] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0030] 1. In the present invention, the middle rod, connecting frame, air storage frame, extrusion frame, and air outlet pipe are adopted. When the pressing rod rotates, through the linkage of the pressing contact rod, connecting sleeve, middle rod, and vertical rod, the downward movement of the middle rod and vertical rod is realized. The downward movement of the middle rod creates space for its separation from the formed gummy. At the same time, the downward movement of the vertical rod squeezes the gas in the air storage frame through the extrusion frame, converting pressure energy into kinetic energy. When the communication hole moves to the position corresponding to the air outlet pipe, the high-pressure gas in the air storage frame quickly discharges through the air outlet pipe, connecting frame, middle rod, and air outlet hole. At this time, the high-pressure air flow instantaneously blown into the space between the mold and the gummy from the air outlet hole effectively destroys the adsorption force between the gummy and the mold. This air flow blowing method realizes the rapid and safe separation between the gummy and the mold, avoiding problems such as deformation and fracture of the gummy caused by mechanical pulling during the traditional ejector pin demolding process, especially suitable for the demolding of high-elastic gummies. In addition, the present invention realizes demolding through air pressure drive, reducing the direct contact between mechanical components and the gummy, reducing the risk of product damage, improving the product qualification rate. The device has a simple structure, is easy to operate and maintain, and can be cleaned without disassembling the mold, effectively reducing production downtime and improving production efficiency.

[0031] 2. In the present invention, with the elastic component, intermediate rod, and second one-way valve, after the pressing rod separates from the contact rod and the extrusion frame releases pressure, the elastic component drives the extrusion frame, vertical rod, connecting frame, and intermediate rod to quickly reset upward. Due to inertia, during the reset process, the intermediate rod will briefly cross the connection hole, move upward and contact the gummy candy. After the aforementioned high-pressure air blowing treatment, the gummy candy that has been initially separated from the mold will be slightly lifted by the upward movement of the intermediate rod. This design cleverly utilizes the inertia of the intermediate rod to achieve secondary auxiliary demolding of the gummy candy. Through this slight upward lifting action, the adsorption force between the gummy candy and the mold is further reduced, making the separation and demolding process between the gummy candy and the mold smoother and safer, effectively avoiding deformation, fracture, or residue of the gummy candy during demolding, ensuring the integrity of the gummy candy, and improving the yield rate of the product.

[0032] 3. In the present invention, with the extrusion wheel, contact protrusion, moving plate, knocking rod, and elastic telescopic rod, when the extrusion wheel rotates and crosses the contact protrusion, the elastic telescopic rod will drive the moving plate and knocking rod to quickly reset. This reset process will generate a slight vibration, which acts on the connecting sleeve, intermediate rod, and mold. This vibration effect cooperates with the action of the intermediate rod pushing the gummy candy upward mentioned before to form a combined demolding force. This demolding method combining vibration and pushing can more effectively overcome the adsorption force between the gummy candy and the mold, making the demolding and separation process of the gummy candy smoother. The vibration effect can further loosen the attachment points between the machine and the gummy candy, while the pushing of the intermediate rod provides an upward thrust. The two work together, enabling the gummy candy to be separated from the mold more easily and safely, effectively avoiding deformation, fracture, or residue of the gummy candy caused by strong pulling, and significantly improving the demolding success rate and the yield rate of the product.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 making creative efforts belong to the scope of protection of the present invention.

[0045] Please refer to the attached Figure 1 - Attachment Figure 9 ,The present invention provides a technical solution: a sandwich-type functional gummy candy preparation device, including a bottom plate 1 and two carrying frames 7. Four support columns 2 are connected to the bottom plate 1, and the top ends of the support columns 2 are fixedly connected to a top plate 3. A mixing and discharging barrel 5 is installed on the top plate 3. Four molds 8 are installed in the carrying frame 7. An extension rod 9 is fixedly connected under the mold 8, and an air pressure reset mechanism 10 is fixedly connected to the end of the extension rod 9. An active ejection mechanism 11 is connected to the air pressure reset mechanism 10. The active ejection mechanism 11 is slidably connected in a connection hole 14 opened under the mold 8. A rotary pressing mechanism 12 connected to the bottom of the mold 8 is arranged on the side of the active ejection mechanism 11. A rotary vibration mechanism 13 installed under the mold 8 is arranged outside the rotary pressing mechanism 12. The two carrying frames 7 are connected to the same moving control mechanism 15 arranged on the bottom plate 1.

[0046] The mixing and discharging barrel 5 is used for mixing raw materials and can suck and discharge the mixed raw materials. The raw materials can be injected into the mold 8 through the discharge pipe 6.

[0047] Specifically, as Figure 1-3 shown, four threaded seats 4 are fixedly connected to the side of the bottom plate 1. Two discharge pipes 6 are communicated outside the mixing and discharging barrel 5. The discharge pipes 6 penetrate and are connected to the top plate 3. The bottom end position of the discharge pipe 6 corresponds to the position of the mold 8.

[0048] Specifically, as Figure 4-6 shown, the air pressure reset mechanism 10 includes an air storage frame 101. The side of the air storage frame 101 is fixedly connected to the extension rod 9. An extrusion frame 102 is slidably connected in the air storage frame 101. An elastic component 104 is fixedly connected under the extrusion frame 102. The elastic component 104 is fixedly connected to the inner wall of the air storage frame 101. An air outlet pipe 105 is communicated with the side of the air storage frame 101. A first one-way valve 106 is arranged outside the air outlet pipe 105.

[0049] The end of the air outlet pipe 105 communicated with the air storage frame 101 is blocked by the extrusion frame 102. A communication hole 107 is opened on the side of the extrusion frame 102. When the communication hole 107 moves downward, it will be communicated with the air outlet pipe 105. A second one-way valve 108 is communicated with the side of the air storage frame 101. The other end of the air outlet pipe 105 is communicated with the active ejection mechanism 11. A vertical rod 103 is fixedly connected to the extrusion frame 102. The vertical rod 103 penetrates and is slidably connected to the air storage frame 101. The top end of the vertical rod 103 is fixedly connected to the active ejection mechanism 11.

[0050] During the downward movement of the extrusion frame 102, the gas in the gas storage frame 101 will be extruded. When the position of the communication hole 107 corresponds to the air outlet 115, the extruded high-pressure gas will enter the air outlet pipe 105. While the vertical rod 103 moves downward, it controls the movement of the extrusion frame 102. When the vertical rod 103 loses the pressing force, the elastic component 104 controls the extrusion frame 102 and the vertical rod 103 to quickly reset upward, and at the same time, sucks the outside gas into the gas storage frame 101 through the second one-way valve 108.

[0051] Specifically, as Figure 6-7 shown, the movable ejection mechanism 11 includes a connecting frame 111 fixedly connected to the top end of the vertical rod 103. Four intermediate rods 112 are fixedly connected to the connecting frame 111. The intermediate rods 112 are slidably connected to the inner wall of the connecting hole 14. Both the intermediate rods 112 and the connecting frame 111 are hollow, and they are communicated with each other. An air outlet 115 is provided on the side surface of the intermediate rod 112. The air outlet pipe 105 is communicated with the air outlet 115 through the connecting frame 111 and the intermediate rod 112. A connecting sleeve 113 is sleeved outside the intermediate rod 112. Contact rods 114 are fixedly connected to both the front and rear sides of the connecting sleeve 113. The contact rods 114 are arranged outside the rotary pressing mechanism 12.

[0052] The high-pressure gas flowing into the air outlet pipe 105 flows out through the connecting frame 111, the intermediate rod 112 and the air outlet 115. When the intermediate rod 112 moves downward, it will move to the wide part of the connecting hole 14. At this time, the gas can flow upward through the connecting hole 14 between the mold 8 and the gummy candy.

[0053] Specifically, as Figure 5-6 and Figure 8 shown, the rotary pressing mechanism 12 includes a first driving component 121. The output shaft of the first driving component 121 is fixedly connected with a first gear 122. A first fixing rod 123 arranged under the mold 8 is fixedly connected to the first driving component 121. The first gear 122 is externally engaged with a second gear 124. A rotary rod 125 penetrates through the side surface of the second gear 124. Four pressing rods 128 are fixedly connected to the outside of the rotary rod 125. The pressing rods 128 are arranged outside the contact rods 114. A rotary vibration mechanism 13 is arranged outside the rotary rod 125. A bearing 126 is sleeved outside the rotary rod 125. A second fixing rod 127 arranged under the mold 8 is fixedly connected to the bearing 126.

[0054] During the rotation of the pressing rod 128, it presses the contact rod 114 and the intermediate rod 112 to move downward until the separation between the pressing rod 128 and the contact rod 114 occurs, and then the above process is continuously repeated, enabling sufficient downward movement of the contact rod 114 and the intermediate rod 112. The first driving assembly 121 controls the rotation of the second gear 124, the rotating rod 125, and the pressing rod 128 through the first gear 122. During the rotation of the pressing rod 128, the contact rod 114, the connecting sleeve 113, the intermediate rod 112, and the vertical rod 103 move downward.

[0055] Specifically, as Figure 5-6 and Figure 8 shown, the rotary vibration mechanism 13 includes an extrusion wheel 131 provided outside the rotating rod 125. A contact protrusion 132 is provided outside the extrusion wheel 131. A moving plate 133 is fixedly connected to the side surface of the contact protrusion 132. One side of the moving plate 133 close to the movable ejecting mechanism 11 is connected with a knocking rod 134. Driven by the moving plate 133, the knocking rod 134 knocks on the connecting sleeve 113 of the movable ejecting mechanism 11.

[0056] A side surface of the moving plate 133 is fixedly connected with an elastic telescopic rod 135. One end of the elastic telescopic rod 135 is fixedly connected with a side plate 136, and the side plate 136 is fixedly connected under the mold 8.

[0057] After the extrusion wheel 131 rotates past the contact protrusion 132 during the rotation process, the elastic telescopic rod 135 controls the rapid reset of the moving plate 133 and the knocking rod 134, and the vibration acts on the connecting sleeve 113, the intermediate rod 112, and the mold 8.

[0058] Specifically, as Figure 1 and Figure 9 shown, the movement control mechanism 15 includes an intermediate plate 151 fixedly connected to the bottom plate 1. Two second driving assemblies 152 are fixedly connected to the intermediate plate 151. Both output shafts of the second driving assemblies 152 are fixedly connected with lead screws 153. The lead screws 153 are externally threaded with threaded nuts 154. A connecting seat 155 is fixedly connected to the outside of the threaded nut 154, and the connecting seat 155 is fixedly connected to the outside of the bearing frame 7.

[0059] The second driving assembly 152 can control the horizontal movement of the threaded nut 154 and the bearing frame 7 through the lead screw 153, facilitating the adjustment of the position of the mold 8.

[0060] A method for preparing a sandwich-type functional soft candy, the preparation method comprising the following steps:

[0061] (1) Preparation of the outer gummy layer: Weigh 8 g of gelatin and soak it in 20 g of water until swollen. Weigh 20 g of erythritol, 55 g of maltitol syrup and 100 g of water, mix and heat until dissolved. Add the swollen gelatin, stir well, heat to 85 °C and keep for 12 minutes. Then add 3 g of vitamin C, 2 g of vitamin E, 6 g of tricalcium phosphate, 10 g of water-soluble dietary fiber and 2 g of flavor and pigment, stir well, and cool to 55 °C for standby;

[0062] (2) Preparation of the inner sandwich layer: Weigh 6 g of gelatin and soak it in 18 g of water until swollen. Weigh 20 g of erythritol, 55 g of maltitol syrup and 100 g of water, mix and heat until dissolved. Add the swollen gelatin, stir well, heat to 95 °C and keep for 18 minutes. Then add 2 g of ferric pyrophosphate, 1 g of zinc citrate, 0.5 g of copper gluconate and 5 g of probiotics (counted as viable bacteria 1×10^9 CFU / g), stir well, and cool to 65 °C for standby;

[0063] (3) Molding step: Use mold 8. First, pour the cooled raw material of the outer gummy layer into mold 8 and fill it to about two-thirds of the capacity of mold 8 to initially form the outer layer. Then, inject the cooled raw material of the inner sandwich layer into mold 8 to fill mold 8, and cool at room temperature for 120 - 180 minutes to initially form the gummy. Then place it in an environment of 25 ± 2 °C and dry for 24 ± 1 hour to completely form the gummy. After demolding, perform individual packaging with an aluminum-plastic composite film to obtain the finished product.

[0064] Working principle, when in use:

[0065] All the raw materials are injected into mold 8 through the mixing and discharging barrel 5. After cooling is completed and when demolding is required, directly control the first driving component 121 to work. The first driving component 121 controls the rotation of the second gear 124, the rotating rod 125 and the pressing rod 128 through the first gear 122. During the rotation of the pressing rod 128, the contact rod 114, the connecting sleeve 113, the intermediate rod 112 and the vertical rod 103 are pressed downward. While the intermediate rod 112 moves downward, it will separate from the formed gummy. While the vertical rod 103 moves downward, it will squeeze the gas in the gas storage frame 101 through the extrusion frame 102;

[0066] When the communication hole 107 moves to the position corresponding to the air outlet pipe 105, at this time, the high-pressure gas in the gas storage frame 101 is discharged through the air outlet pipe 105, the connecting frame 111, the intermediate rod 112 and the air outlet hole 115. At this time, the high-pressure gas discharged from the air outlet hole 115 is instantaneously and quickly blown into the space between mold 8 and the gummy. The airflow blowing in will tear the adsorption force between the gummy and mold 8, enabling the gummy to be quickly and safely separated from mold 8, and it is not easy to cause the situation of the gummy being deformed and broken due to pulling;

[0067] After the separation between the pressing rod 128 and the contact rod 114, at this time, the elastic component 104 controls the extrusion frame 102, the vertical rod 103, the connecting frame 111 and the intermediate rod 112 to quickly reset upward. Due to inertia, the intermediate rod 112 will move upward beyond the connecting hole 14 to contact the gummy candy. The gummy candy that has been initially separated from the mold 8 after blowing treatment is pushed upward. At the same time, after the extrusion wheel 131 rotates past the contact protrusion 132, the elastic telescopic rod 135 will control the moving plate 133 and the knocking rod 134 to quickly reset. The vibration acts on the connecting sleeve 113, the intermediate rod 112 and the mold 8, and the vibration and the pushing action act on the gummy candy, making the demolding and separation of the gummy candy smoother, safer and more efficient.

[0068] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
