Description

Technical Field

[0001] This utility model relates to the field of ice cream demolding technology, specifically to an anti-sticking ice cream demolding device. Background Technology

[0002] In the industrial production of ice cream, after the filled ice cream molds are placed in a quick-freezing tunnel to solidify, a demolding process is required before proceeding to the subsequent packaging process. Currently, the most common demolding method is hot-dip demolding, which involves immersing the ice cream mold in a hot water bath or using steam to spray the outer wall of the mold, causing the surface layer of ice cream that is in close contact with the inner wall of the mold to melt slightly, allowing it to be easily pulled out using an ice cream stick.

[0003] However, hot water tanks require continuous heating and insulation of large amounts of water, resulting in high energy consumption. Furthermore, the open liquid surface can easily lead to a humid and steamy production environment, which does not meet the cleanliness requirements of modern food production. Therefore, we propose an anti-sticking ice cream demolding device. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-sticking ice cream demolding device, comprising: a heating box, two sets of conveying mechanisms symmetrically arranged laterally at the top edge of the heating box, several sets of rotating shafts arranged laterally on the inner wall of the heating box via bearings, a heat-insulating plate fixed to the shaft body of the rotating shaft, an mounting block fixed to the bottom edge of the heat-insulating plate, a mounting column fixed to the end of the mounting block, a rotating roller rotatably connected to the end of the mounting column, a sliding groove opened on the right side of the inner wall of the heating box, a sliding plate slidably connected inside the sliding groove, several sets of sliding rails opened on the left side of the sliding plate, and one end of the sliding plate being fixed... A hydraulic rod is fixed, and the cylinder of the hydraulic rod is fixed to the heating box. A heating pipe is installed not far from the bottom end of the insulation plate. An air cavity is fixed not far from the bottom end of the heating pipe. Several sets of air holes are evenly opened at the top of the air cavity. An air inlet pipe is connected to the middle of the front end of the air cavity. A blower is connected to the front end of the air inlet pipe. The air inlet of the blower is connected to a filter box through a pipe. An exhaust pipe is connected to the rear end of the filter box. The end of the exhaust pipe is connected to the inner cavity of the heating box. A temperature sensor is installed in the inner cavity of the heating box. A top plate is placed at the top of the conveying mechanism. An ice cream mold is fixed at the bottom end of the top plate.

[0005] As a preferred technical solution of this utility model, the insulation board is designed in a flat arc shape, and sealing strips are fixed at both sides of the insulation board. When the insulation board is closed, the sealing strips are tightly fitted with the inner wall of the heating box or the sealing strips of adjacent insulation boards.

[0006] As a preferred embodiment of this utility model, the slide rail has a convex cross-section, the mounting post is slidably connected to the narrow part of the slide rail, and the rotating roller is rollingly connected to the wide part of the slide rail.

[0007] As a preferred embodiment of this utility model, the insulation board rotates along the axis of the rotating shaft under the push of the sliding plate.

[0008] As a preferred embodiment of this invention, the front and rear side walls of the heating box are higher than the left and right side walls, so that the left and right sides form openings for the ice cream mold to enter and exit.

[0009] As a preferred embodiment of this utility model, silicone baffles are fixed at the left and right notches of the heating box, and the height of the upper edge of the silicone baffles is adapted to the height of the ice cream mold to reduce heat loss.

[0010] As a preferred embodiment of this utility model, the filter box is detachably equipped with at least two stages of filter elements, including but not limited to a coarse filter screen and an activated carbon filter element.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) Reduced energy consumption and improved energy efficiency: The equipment adopts a hot air internal circulation design, which returns the hot air that has completed heat exchange in the heating box to the filter box through the exhaust pipe. After filtration, it is sent back into the air cavity to participate in heating, avoiding energy waste caused by direct discharge of hot air. Compared with traditional hot immersion demolding equipment (which requires continuous heating of a large amount of hot water), the energy efficiency is effectively improved. The insulation board, sealing strip and silicone baffle in the closed state form a multi-layer insulation structure, which can greatly reduce heat loss in the heating box, shorten the preheating time and reduce energy consumption.

[0013] (2) Ensuring a clean production environment that meets food production standards: The equipment uses a hot air internal circulation system to effectively maintain the dryness of the production environment; at the same time, the multi-stage filter element in the filter box can remove impurities, dust and moisture from the air, ensuring that the air entering the heating box is clean and preventing contaminants from adhering to the ice cream molds or ice cream surface, which meets the cleanliness requirements of modern food production. Moreover, compared with hot water immersion, hot air heating can avoid direct contact between the mold and water, reduce the risk of mold corrosion, and extend the service life of the mold.

[0014] (3) Improve demolding effect and ensure ice cream quality: Hot air is blown out evenly through several sets of air holes at the top of the air cavity, which can achieve uniform heating of the outer wall of the ice cream mold. At the same time, the operator can adjust the speed of the conveying mechanism to accurately control the heating time of the mold, avoid demolding sticking or ice cream melting, and further ensure the stable demolding effect.

The cylinder of the pressure rod 13 is fixed to the heating box 1. A heating pipe 14 is set not far from the bottom of the insulation plate 5. A wind cavity 15 is fixed not far from the bottom of the heating pipe 14. Several sets of air holes 16 are evenly opened at the top of the wind cavity 15. An air inlet pipe 17 is connected to the middle of the front end of the wind cavity 15. A blower 18 is connected to the front end of the air inlet pipe 17. The air inlet of the blower 18 is connected to a filter box 19 through a pipe. An exhaust pipe 20 is connected to the rear end of the filter box 19. The end of the exhaust pipe 20 is connected to the inner cavity of the heating box 1. A temperature sensor 23 is installed in the inner cavity of the heating box 1. A top plate 21 is placed at the top of the conveying mechanism 2. An ice cream mold 22 is fixed at the bottom of the top plate 21.

[0026] In order to reduce heat loss inside the heating box 1 during the preheating stage of the equipment and achieve rapid heating to reach the preset demolding temperature, while ensuring temperature stability inside the heating box 1 and avoiding energy waste when the insulation plate 5 is closed, in this embodiment, as a preferred technical solution of the present invention, the insulation plate 5 is designed in a flat arc shape, and sealing strips 6 are fixed on both sides of the insulation plate 5. When the insulation plate 5 is closed, the sealing strips 6 are tightly fitted to the inner wall of the heating box 1 or the sealing strips 6 of the adjacent insulation plate 5.

[0027] To ensure stable transmission between the mounting column 8 and the rotating roller 9 within the slide rail 12, and to prevent jamming or deviation during sliding, while limiting the movement trajectory of the mounting column 8 and the rotating roller 9 through the convex structure to ensure the synchronicity and smoothness of the sliding plate 11 driving the insulation plate 5 to rotate, in this embodiment, as a preferred technical solution of the present invention, the slide rail 12 has a convex cross-section, with the mounting column 8 slidingly connected to the narrow part of the slide rail 12, and the rotating roller 9 rollingly connected to the wide part of the slide rail 12.

[0028] In order to convert the linear motion of the sliding plate 11 into the rotational motion of the insulation plate 5, so as to realize the automatic unfolding of the insulation plate 5 when entering the mold and the automatic closing of the insulation plate 5 after exiting the mold without manual intervention and improve demolding efficiency, in this embodiment, as a preferred technical solution of the present invention, the insulation plate 5 rotates along the axis of the rotating shaft 4 under the push of the sliding plate 11.

[0029] In order to provide a stable entry and exit channel for the ice cream mold 22 and ensure that the mold can smoothly enter the heating box 1 for demolding under the drive of the conveying mechanism 2, in this embodiment, as a preferred technical solution of the present invention, the front and rear side walls of the heating box 1 are higher than the left and right side walls, so that the left and right sides form gaps for the ice cream mold 22 to enter and exit.

[0030] In order to seal the gaps on the left and right sides of the heating box 1 by utilizing the soft and adhesive properties of silicone material without affecting the entry and exit of the ice cream mold 22, thereby minimizing the leakage of hot air inside the box and reducing heat loss, while avoiding wear caused by rigid contact between the mold and the baffle, in this embodiment, as a preferred technical solution of the present invention, silicone baffles 3 are fixed at the left and right gaps of the heating box 1. The upper edge height of the silicone baffles 3 is adapted to the height of the ice cream mold 22 to reduce heat loss.

[0031] In order to perform multi-stage purification of the air entering the hot air circulation system, dust and impurities are removed by a coarse filter, and odors and moisture are adsorbed by an activated carbon filter, so as to ensure that the air entering the heating box 1 meets the cleanliness standards for food production. At the same time, the detachable design facilitates the regular replacement and maintenance of the filter elements, ensuring long-term stable filtration effect. In this embodiment, as a preferred technical solution of this utility model, at least two stages of filter elements are detachably installed inside the filter box 19. The filter elements include, but are not limited to, a coarse filter and an activated carbon filter.

[0032] In summary, with the help of the above-described technical solution of this utility model,

[0033] Working principle: Before starting the equipment, the operator turns on the heating tube 14 through the control panel at the front of the heating chamber 1. At this time, the insulation plate 5 is in the initial closed state. Because the insulation plate 5 adopts a flat arc-shaped design and has sealing strips 6 fixed on both sides, when closed, the sealing strips 6 are tightly attached to the inner wall of the heating chamber 1 or the sealing strips 6 of the adjacent insulation plate 5, which can greatly reduce the heat loss inside the heating chamber 1, achieve rapid heating, and ensure that the temperature inside the heating chamber 1 quickly reaches the preset demolding temperature. After the ice cream mold 22 completes the filling and freezing process, it is transferred to the top of the heating chamber 1 through the external conveying system. At this time, the front and rear edges of the top plate 21 at the top of the ice cream mold 22 are in contact with the two sets of conveying mechanisms 2 (chain conveying mechanisms can be selected) symmetrically arranged at the top of the heating box 1. After the conveying mechanism 2 is started, it drives the top plate 21 and the ice cream mold 22 to move stably along the top of the heating box 1. The front and rear side walls of the heating box 1 are higher than the left and right side walls, forming a gap for the ice cream mold 22 to enter and exit. At the same time, the silicone baffles 3 fixed at the gaps on both sides are adapted to the height of the ice cream mold 22. This structural design not only ensures the smoothness of mold conveying, but also avoids excessive heat loss from the front and rear directions inside the heating box 1.

[0034] As the ice cream mold 22 enters the heating chamber 1, the hydraulic rod 13 is activated, and its piston retracts, causing the sliding plate 11, connected to the piston of the hydraulic rod 13, to slide along the slide groove 10 on the right side of the inner wall of the heating chamber 1 towards the hydraulic rod 13. Since the insulation plate 5 is rotatably connected to the inner wall of the heating chamber 1 via the rotating shaft 4, and the mounting block 7 at the bottom edge of the insulation plate 5 cooperates with the slide rail 12 of the sliding plate 11 via the mounting column 8, the movement of the sliding plate 11, through the transmission action of the mounting column 8 and the rotating roller 9, causes the insulation plate 5 to rotate downwards around the rotating shaft 4. When the sliding plate 11 moves to the preset position, the insulation plate 5 is in a vertical state, providing a passage for hot air. Simultaneously, the blower 18 is activated, and the external air, filtered by the filter box 19, effectively removes impurities, dust, and moisture from the air, ensuring that the air entering the heating chamber 1 meets the cleanliness standards for food production. Filtered clean air enters the air chamber 15 through the air inlet pipe 17 and is blown upwards through several sets of air holes 16 evenly distributed at the top of the air chamber 15, forming a uniform hot airflow. Meanwhile, the heating pipe 14 continues to operate, heating the air inside the heating chamber 1. The hot airflow acts on the outer wall of the ice cream mold 22, causing the surface layer of the ice cream, which is tightly attached to the inner wall of the mold, to slightly melt, thus breaking the adhesive structure between the ice cream and the inner wall of the mold. Simultaneously, after heat exchange, the hot air inside the heating chamber 1 flows back to the filter box 19 through the exhaust pipe 20, is filtered again, and then sent back into the air chamber 15 by the blower 18, forming a complete internal hot air circulation system. This circulation structure avoids energy waste caused by direct exhaust of hot air, significantly reducing equipment energy consumption; and during the circulation process, the air is constantly filtered, effectively preventing external contaminants from entering the heating chamber 1 and ensuring the cleanliness of ice cream production.

[0035] A temperature sensor 23 installed inside the heating chamber 1 monitors the internal temperature in real time and feeds the temperature data back to the control system. When the internal temperature reaches the preset demolding threshold—a temperature that slightly melts the surface of the ice cream without causing the entire ice cream to melt—the control system automatically adjusts the heating element 14 to a low power setting or turns it off to prevent excessive heat from degrading the quality of the ice cream. If the temperature is below the threshold, the heating element 14 automatically resumes high power heating to ensure that the temperature inside the heating chamber 1 remains stable within the optimal demolding range. Furthermore, operators can adjust the speed of the conveyor mechanism 2 to control the dwell time of the ice cream mold 22 within the heating chamber 1, further precisely controlling the heating effect and preventing insufficient heating leading to sticking during demolding or excessive heating leading to melting of the ice cream. After the ice cream mold 22 has completed heating and demolding, the conveyor mechanism 2 continues to move the mold to the other side of the heating chamber 1, outputting it from the opening of the heating chamber 1 for subsequent ice cream extraction and packaging processes. The blower model mentioned above is YN5-47; the motor model is for reference only and should meet operational requirements.
