Description

Technical Field

[0001] This utility model relates to the technical field of ice cream demolding devices, and in particular to a rapid ice cream demolding device. Background Technology

[0002] In the ice cream making process, the prepared liquid slurry is poured into a mold of a specific shape, and then placed in a low-temperature environment to freeze and solidify completely. Once it is fully frozen and hard, the formed ice cream is carefully removed from the mold cavity without damage, completing the demolding process. This is a crucial step in ensuring the final ice cream has a beautiful and intact shape. However, during the freezing process, the water in the ice cream slurry crystallizes and adheres tightly to the inner wall of the mold, especially in the intricately designed edges, corners, or deep areas at the bottom of the mold. Due to the strong bonding of the ice crystals, a tight physical adhesion occurs, making this localized adhesion particularly stubborn during demolding and becoming a major obstacle to achieving efficient and damage-free demolding.

[0003] To address the aforementioned issues, existing common technical methods mainly rely on two approaches: one is to apply heat to the entire mold, such as by spraying or soaking with warm water, aiming to melt the ice crystals at the adhesion points through heat transfer, thereby loosening the ice cream; the other is to use mechanical external force, such as a push rod directly acting on the ice cream to force separation. However, the overall warm water treatment method inevitably causes all surface areas of the ice cream to receive the same intensity of heat input, and the heating time depends on the speed at which the most firmly adhered areas and the slowest melting of ice crystals reach the separation conditions. This inevitably leads to excessive heat accumulation on the surface of the ice cream in non-adhesive areas that do not require much heat, causing local over-softening or even melting, significantly damaging the texture and taste of the ice cream. While mechanical push rod forced demolding avoids the risk of heat damage, because it applies rigid, non-flexible point-like or line-like concentrated force, it is very easy for the ice cream to break, scratch the surface, or be distorted and deformed near the adhesion points when dealing with stubborn local adhesions due to uneven force, which also fails to guarantee the integrity and aesthetics of the product. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an ice cream quick demolding device, which solves the problem that the demolding with warm water can easily cause the ice cream to soften excessively or even melt in some places, which significantly damages the texture and taste of the ice cream.

[0005] According to an embodiment of this utility model, an ice cream rapid demolding device includes a base, on which a demolding template is fixedly disposed. Several demolding sleeves are arranged side-by-side on the demolding template for embedding and fixing ice cream molds. A heating sleeve is arranged around the outer edge of the side wall of any of the demolding sleeves. A heating cavity is formed between the heating sleeve and the demolding sleeve. A heating inlet pipe and a heating outlet pipe communicating with the inside and outside of the heating cavity are fixedly disposed in the heating cavity. A first hot water tank is fixedly disposed on one side of the base. A heating source is fixedly disposed in the first hot water tank. The first hot water tank is connected to the heating inlet pipe. A drive source capable of transferring hot water is also fixedly disposed on one side of the first hot water tank.

[0006] The technical principle of this invention is as follows: When the device is working, the mold containing frozen ice cream is embedded and fixed in the demolding box. The drive source transfers the hot water heated by the heating source in the first hot water tank to the heating cavity surrounding the side wall of the demolding box. The hot water flows continuously in the heating cavity and directly heats the outside of the mold. This continuous flow and surrounding heat exchange method allows the heat to be applied precisely and concentratedly to the corresponding ice crystal-bonded areas on the mold, such as the edges and corners of the ice cream and the bottom. By applying controllable heat input to these key adhesion points, the ice crystals are melted quickly to release the adhesion without uniformly heating the entire mold or ice cream surface. Once the target adhesion points are effectively released, the ice cream can be easily and completely removed.

[0007] Furthermore, a first water inlet pipe connected to the first hot water tank is fixedly installed inside the base, and the first water inlet pipe is connected to any of the heating inlet pipes.

[0008] Furthermore, the driving source includes a first high-pressure pump, the input end of which is connected to the first hot water tank, and the output end of which is connected to the first water inlet pipe.

[0009] Furthermore, the heating inlet pipe is connected to the bottom of the heating sleeve, and the heating outlet pipe is connected to the top of the heating sleeve.

[0010] Furthermore, a second hot water tank is fixedly installed on one side of the base, and a first water outlet pipe connected to the second hot water tank is fixedly installed inside the base, with the heating outlet pipe connected to the first water outlet pipe.

[0011] Furthermore, a preheating cavity is fixedly provided between any two adjacent columns of the demolding boxes. The preheating cavity is respectively provided with a preheating inlet pipe and a preheating outlet pipe that connect the inside and outside. The preheating inlet pipe is connected to the second hot water tank, and the preheating outlet pipe is connected to the first hot water tank.

[0012] Furthermore, a second high-pressure pump is fixedly installed on one side of the base. The input end of the second high-pressure pump is connected to the first hot water tank, and its output end is connected to a second water inlet pipe. The second water inlet pipe is connected to any of the preheating inlet pipes.

[0013] Furthermore, a second water outlet pipe connected to the first hot water tank is fixedly installed inside the base, and the second water outlet pipe is connected to any of the preheating outlet pipes.

[0014] Furthermore, the heating source includes a heating wire for heating the water in the first hot water tank.

[0015] Compared with the prior art, this utility model has the following beneficial effects: by setting a heating cavity around a specific area of ​​the demolding box and circulating hot water for precise and controllable local heating, the stubborn ice crystals at the edges and bottom of the ice cream are precisely melted instead of the whole ice cream. This effectively solves the problem of excessive softening or melting of ice cream in some areas caused by the existing whole-ice cream demolding method with warm water, and significantly improves demolding efficiency and the texture and taste of ice cream.

Detailed Implementation

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-7 As shown in the figure, this utility model embodiment proposes an ice cream quick demolding device, including a base 2, which is fixedly installed. A demolding template 21 is fixedly installed on the top of the base 2. Several demolding sleeves 22 that match the ice cream mold 1 are arranged side by side on the demolding template 21 for the ice cream mold 1 to be embedded and fixed. A heating sleeve 23 is arranged around the outer edge of the side wall of any demolding sleeve 22. A heating cavity 24 is formed between the heating sleeve 23 and the demolding sleeve 22. A heating inlet pipe 241 and a heating outlet pipe 242 communicating with the inside and outside are fixedly installed in the heating cavity 24. A first hot water tank 3 is fixedly installed on one side of the base 2. A heating source 5 is fixedly installed in the first hot water tank 3. The first hot water tank 3 is connected to the heating inlet pipe 241. A drive source that can transfer hot water is also fixedly installed on one side of the first hot water tank 3.

[0026] In this embodiment, based on the common shape of the ice cream mold 1, a single demolding sleeve 22 can be configured as a downwardly extending rectangular sleeve structure with a waist-shaped or rectangular cross-section and rounded corners on the bottom surface. Multiple demolding sleeves 22 are arranged horizontally and vertically at equal intervals. Furthermore, the shape, number, and relative positions of the demolding sleeves 22 can be set according to the actual situation of the ice cream mold 1, and are not limited here. The demolding sleeve 22 can be made of food-grade stainless steel, which is corrosion-resistant and has excellent thermal conductivity, efficiently transferring heat from hot water to the ice cream mold 1 for rapid and uniform heat transfer demolding. The heating sleeve 23 surrounds and wraps around the side walls and bottom wall of the demolding sleeve 22 to form a uniform and... The continuous heating chamber 24, with the heating inlet pipe 241 and heating outlet pipe 242 connected and arranged at any position in the heating chamber 24, are used for hot water entry and exit respectively. The heating source 5 in the first hot water tank 3 heats the water and then transfers the water to each heating chamber 24 through the drive source to continuously provide heat. Furthermore, the first hot water tank 3 is also provided with a water inlet and a water outlet for replenishing, draining or changing water. Temperature, pressure and other monitoring devices should also be installed on the first hot water tank 3 and the conveying pipe to monitor the real-time temperature, pressure and other parameters of the hot water, so as to facilitate more precise control of the hot water in the heating chamber 24. Since this part is a very mature prior art, those skilled in the art should understand it and will not be described in detail here.

[0027] When the device of this invention is in operation, the mold containing frozen ice cream is embedded and fixed in the demolding box 22. The drive source transfers the hot water heated by the heating source 5 in the first hot water tank 3 to the heating cavity 24 surrounding the side wall of the demolding box 22. The hot water flows continuously in the heating cavity 24 and directly transfers heat to the outside of the mold. This continuous flow and surrounding heat exchange method allows the heat to be applied precisely and concentratedly to the corresponding ice cream edges and corners and the areas on the bottom of the mold where the ice crystals are firmly bonded. By applying controllable heat input to these key bonding areas, the ice crystals at these locations are quickly melted to release the bond, without the need to uniformly heat the entire mold or ice cream surface. Once the target bonding points are effectively released, the ice cream can be easily and completely removed.

[0028] This invention provides precise and controllable local heating by setting up a heating cavity 24 around a specific area of ​​the demolding box 22 and circulating hot water. This precisely melts the stubborn ice crystals at the edges and bottom of the ice cream, rather than the entire ice cream, effectively solving the problem of excessive softening or melting of ice cream in certain areas caused by the existing whole-ice cream demolding method with warm water. This significantly improves demolding efficiency and the texture and taste of the ice cream.

[0029] like Figure 1-7As shown, according to another embodiment, a first water inlet pipe 32 communicating with the first hot water tank 3 is fixedly installed in the base 2. One end of the first water inlet pipe 32 is connected to the output end of the drive source and communicates with the first hot water tank 3, and the other end is connected to any of the heating inlet pipes 241.

[0030] In this embodiment, the first water inlet pipe 32 can be made of stainless steel. The other end of the first water inlet pipe 32 can be divided into several sub-pipes corresponding to the number of rows according to the arrangement of the demolding boxes 22. That is, each row of demolding boxes 22 corresponds to a sub-pipe, and each sub-pipe is connected to the heating inlet pipe 241 of its corresponding row. Each sub-pipe will independently deliver hot water to the heating chamber 24 of all demolding boxes 22 in the same row in parallel, realizing row-by-row synchronous heating control, ensuring a high degree of consistency in the heating intensity and activation time of each row of molds, effectively reducing the temperature difference fluctuation during the demolding process of the same batch of ice cream, thereby significantly improving the demolding efficiency and the stability of demolding quality while ensuring accurate local de-adhesion effect.

[0031] like Figure 1-7 As shown, according to another embodiment, the driving source includes a first high-pressure pump 31, the input end of the first high-pressure pump 31 is connected to the first hot water tank 3, and its output end is connected to the first water inlet pipe 32.

[0032] In this embodiment, the driving source includes other pumps or mechanisms such as high-pressure pumps, gas-liquid booster pumps, or variable frequency centrifugal pumps that can forcibly establish stable water flow pressure, ensuring that the hot water in the heating chamber 24 can maintain sufficient flow rate and volume in the complex branch pipeline, so that the heat transfer process of each row of demolding sleeves 22 can obtain equal heat source support synchronously, and maintain the stability and controllability of the ice crystal melting efficiency of key bonding parts.

[0033] like Figure 1-7 As shown, according to another embodiment, the heating inlet pipe 241 is connected to the bottom of the heating sleeve 23, and the heating outlet pipe 242 is connected to the top of the heating sleeve 23. The heating outlet pipe 242 can be configured as two pipes and symmetrically arranged on both sides of the heating sleeve 23 to facilitate the uniform flow of hot water.

[0034] In this embodiment, the hot water entering from the heating inlet pipe 241 naturally fills the heating chamber 24 from bottom to top, forming a uniform wrapping heat transfer to the mold sidewall from bottom to top. The principle of heat convection is used to enhance the flow coverage of hot water in the vertical direction, which not only avoids local overheating or heating blind spots, but also accelerates the circulation and discharge through dual outlets, significantly improving the heat exchange efficiency of key adhesion areas on the mold sidewall.

[0035] like Figure 1-7As shown, according to another embodiment, a second hot water tank 4 is also fixedly installed on one side of the base 2, and a first water outlet pipe 43 communicating with the second hot water tank 4 is fixedly installed inside the base 2, and the heating outlet pipe 242 is connected to the first water outlet pipe 43.

[0036] In this embodiment, the second hot water tank 4 is basically the same as the first hot water tank 3, and also has an inlet, an outlet, and monitoring equipment such as temperature and pressure, which will not be described in detail here. The first outlet pipe 43 can also be made of stainless steel. One end of the first outlet pipe 43 is connected to the second hot water tank 4, and the other end can be divided into several branch pipes according to the arrangement of the demolding boxes 22. Specifically, the branch pipes are set between adjacent rows of demolding boxes 22 and outside the first and last rows of demolding boxes 22. That is, the heating outlet pipes 242 of adjacent rows of demolding boxes 22 share a section of branch pipe, while the heating outlet pipes 242 of the outermost demolding boxes 22 in the first and last rows are each connected to an independent branch pipe. The hot water discharged from the heating chamber 24 can be collected and recycled to the second hot water tank 4 through the first outlet pipe 43. The hot water in the second hot water tank 4 can be reused in the first hot water tank 3 to realize the continuous recycling of hot water, which not only greatly reduces water consumption, but also makes full use of waste heat to reduce the energy replenishment demand of the heating source 5, and improves the overall energy efficiency and economy of the device.

[0037] like Figure 1-7 As shown, according to another embodiment, a preheating cavity 25 is fixedly provided between any two adjacent columns of the demolding sleeves 22. The preheating cavity 25 is formed by the outer wall of the adjacent heating sleeve 23 and the sealing plate 253 surrounding and sealing it. The preheating cavity 25 is respectively fixedly provided with a preheating inlet pipe 251 and a preheating outlet pipe 252 that communicate with the inside and outside. The preheating inlet pipe 251 is located below the preheating outlet pipe 252. The preheating inlet pipe 251 is connected to the second hot water tank 4, and the preheating outlet pipe 252 is connected to the first hot water tank 3.

[0038] In this embodiment, the sealing plate 253 can also be made of stainless steel. The preheating chamber 25 can receive the recycled hot water flow from the second hot water tank 4 and perform wrap-around preheating on the non-critical adhesion area or flat area of ​​the ice cream mold 1 from bottom to top. This not only realizes the tiered utilization of recycled heat energy, but also forms a safe temperature layer lower than the main heating zone because the temperature of the recycled hot water has been appropriately reduced. This accelerates demolding while avoiding the risk of softening or melting of ice cream in non-target areas.

[0039] like Figure 1-7As shown, according to another embodiment, a second high-pressure pump 41 is fixedly installed on one side of the base 2. The input end of the second high-pressure pump 41 is connected to the first hot water tank 3, and its output end is connected to a second water inlet pipe 42. The second water inlet pipe 42 is connected to any of the preheating inlet pipes 251. A second water outlet pipe 33 connected to the first hot water tank 3 is also fixedly installed inside the base 2. The second water outlet pipe 33 is connected to any of the preheating outlet pipes 252. Specifically, the second water inlet pipe 42 and the second water outlet pipe 33 can be divided into several branch pipes according to the arrangement of the demolding sleeves 22. The branch pipes of both can be set between adjacent rows of demolding sleeves 22. That is, the preheating inlet pipes 251 of adjacent rows of demolding sleeves 22 share a section of the second water inlet pipe 42, and the preheating outlet pipes 252 of adjacent rows of demolding sleeves 22 share a section of the second water outlet pipe 33.

[0040] In this embodiment, the second high-pressure pump 41 can also be configured as a gas-liquid booster pump, a variable frequency centrifugal pump, or other pump body or mechanism that can forcibly establish a stable water flow pressure to ensure stable water pressure in each pipe. The input end of the second high-pressure pump 41 is connected to the first hot water tank 3, and the output end is split into several branch pipes through the second water inlet pipe 42, so that the preheating inlet pipes 251 of adjacent rows of demolding sleeves 22 share the same section of branch pipe. At the same time, a second water outlet pipe 33 is set to connect to the preheating outlet pipe 252 and return to the first hot water tank 3. The preheating outlet pipes 252 of adjacent rows also share the branch pipe. The hot water in the second hot water tank 4 is transported to the first hot water tank 3 for circulation and reuse, thus constructing an independent preheating circulation pipeline. The synchronous delivery of multiple preheating chambers 25 is achieved through a simplified spatial layout.

[0041] like Figure 1 As shown, the heating source 5 includes a heating wire for heating the water in the first hot water tank 3.

[0042] In this embodiment, the heating wire can be replaced by other heat sources such as an electromagnetic induction heater or a steam coil to directly and accurately control the temperature of the water in the first hot water tank (3) and ensure a continuous supply of the water temperature required for demolding.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
