Description

Technical Field

[0001] This invention relates to the field of ice cream production, and in particular to a coating device for a large-headed crispy cone and a method for preparing the large-headed crispy cone. Background Technology

[0002] Currently, there is an ice cream product called "Big Head Crispy Cone," which comes in various flavors. For example, some products have a chocolate layer coated on the top, while others sprinkle coconut ash or shredded coconut on top of the chocolate layer. The existing technology for coating the outer layer of the Big Head Crispy Cone involves using a clamp to hold the cone in a semi-automatic or manually controlled manner, then inverting it and placing it into a slurry tank to coat the surface with chocolate or other slurry. Finally, coconut ash or shredded coconut powder is sprinkled on top manually. This method has the following drawbacks:

[0003] 1. Manual operation, high labor intensity, unable to achieve mass production, and low production efficiency;

[0004] 2. Manually sprinkling coconut flakes results in significant waste of solid ingredients such as coconut flakes. If chocolate coating is used, the solid ingredients will compress the larger end of the cone, damaging its shape and affecting the product's appearance.

[0005] Based on the above problems, this invention develops a coating device for large-head crispy rice tubes that can achieve mass production and produce high-quality products, as well as a method for preparing large-head crispy rice tubes. Summary of the Invention

[0006] The present invention aims to solve the technical problems existing in the prior art. To this end, the present invention provides a coating device for large-head crispy rice tubes that enables mass production and produces high-quality products, as well as a method for preparing large-head crispy rice tubes.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] The present invention provides a coating hanging device for a large-head crispy rice tube, comprising a chain circulation mechanism, a plurality of material-carrying mechanisms disposed on the transmission chain of the chain circulation mechanism for clamping the crispy rice tube, and a hanging mechanism disposed below the chain circulation mechanism.

[0009] The material loading mechanism includes a material loading plate and a pin assembly. The material loading plate has multiple material inlets along its length. The pin assembly includes pins located at the front and rear ends of each material inlet. All pins at the front end and all pins at the rear end of each material inlet are fixedly connected to connecting rods movably mounted on the material loading plate. The two ends of the two connecting rods pass through a U-shaped groove on the material loading plate via limiting rods.

[0010] The top two ends of the chain circulation mechanism are respectively provided with a first driving component that acts on the end of the connecting rod to insert the pin into the crispy tube and a second driving component that pulls the pin out of the crispy tube;

[0011] In this embodiment, a resin sleeve is preferably fitted onto the exposed end of the limiting rod, so that the interaction between the first drive assembly and the second drive assembly that control the movement of the limiting rod and the resin sleeve can achieve the purpose of noise reduction.

[0012] The material hanging mechanism adopts a lifting type. The chain circulation mechanism sends the crispy shell tube on the material loading mechanism to the top of the material hanging mechanism. At this time, the crispy shell tube is in an inverted state. The material hanging mechanism is lifted, and the outer material inside sticks to the large end surface of the crispy shell tube.

[0013] In a preferred embodiment of the present invention, both the first driving assembly and the second driving assembly include actuators disposed on both sides of the chain circulation mechanism and acting on the ends of the connecting rods on both sides of the material carrier plate, wherein the actuators are pneumatic cylinders, hydraulic cylinders, electric actuators, or electro-hydraulic actuators.

[0014] In a preferred embodiment of the present invention, the material hanging mechanism includes a slurry hanging mechanism and / or a solid fragment hanging mechanism, and the discharge end of the slurry hanging mechanism and / or the solid fragment hanging mechanism is provided with a receiving groove for receiving the dripping external material.

[0015] When both a slurry coating mechanism and a solid material coating mechanism are set up simultaneously, the solid material coating mechanism is located behind the slurry coating mechanism, so that the brittle tube is coated with a slurry layer first and then with solid materials.

[0016] In a preferred embodiment of the present invention, the slurry loading mechanism includes an insulation box, a stirring device disposed in the insulation box, a slurry container disposed in the insulation box, and a lifting device disposed at both ends of the container to control the lifting and lowering of the container.

[0017] The insulated box is equipped with a double layer, and a heating medium is circulated into the double layer for heating.

[0018] The slurry is fed into the slurry tank through a pipe, and the liquid level of the slurry exceeds the top of the slurry tank.

[0019] In a preferred embodiment of the present invention, the solid scrap material hanging mechanism includes a base, a solid scrap material box disposed above the base, a lifting device disposed at both ends of the base to control the lifting and lowering of the solid scrap material box, and a plurality of guide posts with one end fixed to the base and the other end extending through the solid scrap material box to the opening of the box. Each guide post corresponds to the material placement port on the material carrier plate, and the top of the guide post is a cone shape.

[0020] Solid materials include powder, granules, and fragments. The filling height of solid materials in the solid materials bin is flush with the upper surface of the guide column. After the solid materials bin is lifted, the guide column is used to form an inverted conical recess in the solid materials.

[0021] In a preferred embodiment of the present invention, a plurality of the material-carrying mechanisms form a set of material-carrying units, and the transmission chain is provided with multiple sets of material-carrying units, so as to facilitate the addition of external materials to the hanging mechanism through the gaps between the material-carrying units.

[0022] In a preferred embodiment of the present invention, the material inlet is a circular opening with a diameter smaller than the maximum diameter of the crispy tube. The circular opening is provided with a multi-lobed downward inclined fan-shaped guide plate. The fan-shaped guide plate is positioned to avoid the insertion pin, and the fan-shaped guide plate is formed by cutting and bending the upper surface of the material carrier plate.

[0023] The present invention also provides a method for preparing a large-headed crispy cone, which involves filling the crispy cone with milk and then quick-freezing it. The outer coating material is then applied to the large-headed surface of the crispy cone using the outer coating material application device described in the above embodiments. The cone is then quick-frozen, inkjet-coded, packaged, and inspected to obtain the finished product.

[0024] The material application method of the external coating application device is as follows:

[0025] The material loading mechanism near the first drive component of the device is the feeding area, and the material loading mechanism near the second drive component is the unloading area. The crispy tube after being filled with milk and quick-frozen is placed in the feeding port on the material loading plate.

[0026] When the material carrier plate is delivered to the position of the first drive assembly, the chain circulation mechanism stops conveying, and the first drive assembly controls the pin of the pin assembly to insert the pin into the crispy tube and fix the crispy tube.

[0027] The chain circulation mechanism continues to convey material until the material plate is delivered directly above the hanging mechanism. At this time, the crispy tube is inverted with its large end facing down. The material box of the hanging mechanism is then lifted to allow the large end of the crispy tube to enter the material box to a certain depth, thus completing the coating of the material on the surface of the large end of the crispy tube.

[0028] After the outer material of the crispy shell tube is finished, the chain circulation mechanism continues to send the material loading mechanism to the position of the second drive component and then stops conveying. The second drive component controls the pin insertion component to pull the pin out of the crispy shell tube, and the crispy shell tube is released from the fixed state.

[0029] After the crispy shell tube is released from its fixed state, it is conveyed to the unloading area, removed, and then the subsequent processes continue.

[0030] In the above preparation method, the external material includes one or more combinations of slurry, powder, and granules, wherein: the slurry includes chocolate, the powder includes shredded coconut, and the granules include crushed peanuts and crushed coconut flakes.

[0031] In the above preparation method, the expansion rate of the milk material is 130%~140%, the filling temperature is ≤-3.5℃, the height of the milk material for latte art is 5~5.5cm, and the diameter of the latte art is 6±0.5cm;

[0032] In the above preparation method, both the inner and outer surfaces of the crispy tube are coated with chocolate. The coating temperature of the chocolate is 38~43℃. The chocolate coating is of uniform thickness and completely covers the crispy tube without any white showing. The chocolate sinks to the bottom at a depth of no more than 1cm.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. The present invention utilizes a first driving component to fix multiple crispy tubes placed on each material carrier plate into the material inlet through a pin assembly. The crispy tubes are then conveyed to the top of the hanging mechanism by the chain circulation mechanism. At this time, the crispy tubes are in an inverted state with the large end facing down. The hanging mechanism lifts the material box to complete the coating of the material on the outer surface of the large end of the crispy tube. After coating, the second driving component is used to release the crispy tubes from the fixation, thereby realizing automated mass production, improving production efficiency, and reducing labor costs.

[0035] 2. The designed material hanging mechanism includes a slurry hanging mechanism and a solid fragment hanging mechanism. The solid fragment hanging mechanism will not damage the large end of the brittle tube when hanging materials, ensuring the appearance quality of the product. Compared with the method of sprinkling materials, it will not cause waste. Attached Figure Description

Example 1

[0048] This embodiment provides a coating device for a large-headed crispy rice tube, as shown in the attached image. Figure 1 and attached Figure 2 As shown, it includes a chain circulation mechanism, several material-carrying mechanisms 2 mounted on the transmission chain 1 of the chain circulation mechanism for clamping the crispy tubes, and a material-hanging mechanism 3 located below the chain circulation mechanism, wherein:

[0049] The chain circulation mechanism is installed on both sides of the frame and consists of two driving sprockets, a driven sprocket, and a transmission chain. The driving sprockets are driven by a servo motor.

[0050] Mounting lugs 4 are fixedly installed on the inner sides of the two transmission chains 1. The two ends of the material carrying mechanism 2 are detachably connected to the mounting lugs 4. In this embodiment, the preferred detachable connection method is: through holes are provided at both ends of the material carrying mechanism, and pins are provided on the mounting lugs. The pins are fixed by passing through the through holes and being secured by pins. In other embodiments, the mounting lugs and the material carrying mechanism can also be detachably connected by snap-fit, bolt connection, or other methods.

[0051] Preferred options are listed below. Figure 3 and attached Figure 4 As shown, the material-carrying mechanism 2 includes a material-carrying plate 2.1 and a pin assembly. The material-carrying plate 2.1 has multiple material inlets 2.1.0 along its length, each inlet capable of holding one crispy rice cake tube. Preferably, the material inlet 2.1.0 is a circular opening with a diameter smaller than the maximum diameter of the crispy rice cake tube. The pin assembly includes pins 2.2 located at the front and rear ends of each material inlet 2.1.0. All pins 2.2 at the front and rear ends of each material inlet 2.1.0 are fixedly connected to connecting rods 2.3 movably mounted on the material-carrying plate 2.1. The two ends of the connecting rods 2.3 pass through a U-shaped groove on the material-carrying plate 2.1 via limiting rods 2.4. By pushing the two connecting rods towards each other, the pins can be inserted into the crispy rice cake tube to fix it at the material inlet, or the pins can be pulled out of the crispy rice cake tube to release it from fixation.

[0052] As attached Figure 2 As shown, the top two ends of the chain circulation mechanism are respectively provided with a first driving component 5a that acts on the end of the connecting rod 2.3 to insert the pin 2.2 into the crispy tube and a second driving component 5b that pulls the pin out of the crispy tube. Preferably, in this embodiment, the first driving component 5a and the second driving component 5b both include actuators 5.1 located on both sides of the chain circulation mechanism and acting on the ends of the connecting rods 2.3 on both sides of the material plate 2.1. The actuators 5.1 are cylinders, hydraulic cylinders, electric actuators, or electro-hydraulic actuators. In this embodiment, a cylinder is preferred.

[0053] Preferably, in this embodiment, a resin sleeve is fitted onto the exposed end of the limiting rod 2.4, so that the interaction between the first drive assembly and the second drive assembly that control the movement of the limiting rod and the resin sleeve can achieve the purpose of noise reduction.

[0054] As attached Figure 1 As shown, the hanging mechanism 3 adopts a lifting hanging mechanism. The chain circulation mechanism sends the crispy shell tube on the loading mechanism 2 to the top of the hanging mechanism 3. At this time, the crispy shell tube is in an inverted state. The hanging mechanism 3 is lifted, and the outer material inside sticks to the large end surface of the crispy shell tube.

[0055] Preferably, the material hanging mechanism 3 in this embodiment includes a slurry hanging mechanism 3a and / or a solid fragment hanging mechanism 3b, and the discharge end of the slurry hanging mechanism 3a and / or the solid fragment hanging mechanism 3b is provided with a receiving groove 6 for receiving the dripping external material.

[0056] Preferably, in this embodiment, when both the slurry coating mechanism 3a and the solid fragment coating mechanism 3b are provided, the solid fragment coating mechanism 3b is located behind the slurry coating mechanism 3a, so that the brittle tube is coated with a slurry layer first and then with solid fragments.

[0057] In this embodiment, the first driving component fixes multiple crispy tubes placed on each material carrier plate into the material inlet using a pin assembly. The tubes are then conveyed to the hanging mechanism by the chain circulation mechanism. At this time, the crispy tubes are in an inverted state with the large end facing down. The hanging mechanism lifts the material box to complete the coating of the material on the outer surface of the large end of the crispy tube. After coating, the second driving component releases the crispy tubes from the fixation, realizing automated mass production, improving production efficiency, and reducing labor costs. Example 2

[0058] Based on Example 1, this example further designs the slurry coating mechanism 3a, as shown in the attached figure. Figure 7 As shown, the slurry loading mechanism 3a in this embodiment includes an insulation box 3a.1, a stirring device 3a.2 disposed inside the insulation box, a slurry container 3a.3 disposed inside the insulation box, and a lifting device 3a.4 disposed at both ends of the container to control its lifting and lowering.

[0059] The insulation box 3a.1 is provided with a jacket, and a heating medium is introduced into the jacket for heating. The heating medium can be steam, hot water, hot oil, etc. In this embodiment, steam is preferred. The insulation box is heated by steam to ensure that the slurry in the insulation box is in a molten state.

[0060] The stirring device 3a.2 is used to stir the slurry to prevent the slurry (such as chocolate) from solidifying locally in the heat preservation box and affecting the coating effect of the external coating material.

[0061] The slurry tank 3a.3 is located inside the insulation box and below the liquid level of the slurry. This design ensures that the slurry tank is full after it is lifted.

[0062] The lifting device 3a.4 is used to lift the slurry box and can be a cylinder, hydraulic cylinder, electric actuator, etc. In this embodiment, a cylinder is preferred.

[0063] The slurry is fed into the slurry tank through a pipe, and its liquid level exceeds the top of the slurry tank. When the loading mechanism is above the slurry tank, the lifting device controls the slurry tank to rise. The slurry tank filled with slurry is submerged to a certain depth in the large end of the brittle tube, thus completing the process of hanging the slurry on the large end. Example 3

[0064] Based on Example 1, this example further designs the solid scrap material hanging mechanism 3b, as shown in the attached figure. Figure 5 and attached Figure 6 As shown, the solid waste material hanging mechanism 3b in this embodiment includes a base 3b.1, a solid waste material box 3b.2 disposed above the base, lifting devices 3b.3 disposed at both ends of the base to control the lifting and lowering of the solid waste material box, and multiple guide posts 3b.4 with one end fixed to the base and the other end extending through the solid waste material box to the opening of the box. Each guide post 3b.4 corresponds to the material placement port 2.1.0 on the material carrier plate 2.1, and the top of the guide post 3b.4 is a cone shape. The lifting device 3b.3 is used to lift the solid waste material box and can be a cylinder, hydraulic cylinder, electric actuator, etc. In this embodiment, a cylinder is preferred.

[0065] Solid materials include powder, granules, and fragments. The filling height of the solid materials in the solid materials bin is flush with the upper surface of the guide column. After the solid materials bin is lifted, the guide column forms an inverted conical recess 100. The solid materials bin designed in this embodiment can form an inverted conical recess when the solid materials bin is lifted. The presence of this recess can accommodate the large end of the brittle tube without compressing or damaging its appearance, thus ensuring the product's appearance quality. Moreover, compared to the method of scattering materials, there is no waste. Example 4

[0066] Based on any of the embodiments described in Examples 1 to 3, as shown in the appendix Figure 1 As shown, multiple material-carrying mechanisms 2.1 form a set of material-carrying units. Multiple sets of material-carrying units are provided on the transmission chain 1, with a feeding gap 200 between two sets of material-carrying units to facilitate the addition of external materials to the hanging mechanism through the gap. In this embodiment, the main purpose is to add solid fragments to the solid fragment hanging mechanism 3b; slurry, due to its fluidity, can be directly fed into the slurry hanging mechanism through a pipe.

[0067] Preferably, a melting tank can be provided on one side of the device. For example, a special substance such as chocolate can be melted in the melting tank and then sent to the slurry coating mechanism through a pipe. Example 5

[0068] Based on any of the embodiments described in Examples 1 to 4, as shown in the appendix Figure 3 and attached Figure 4As shown, in this embodiment, a multi-lobed, downwardly inclined fan-shaped guide plate 2.1.1 is provided inside the circular opening of the material inlet 2.1.0. The fan-shaped guide plate is positioned to avoid the insertion pin 2.2, and the fan-shaped guide plate 2.1.1 is formed by cutting and bending the upper surface of the material carrier plate 2.1. The design of the fan-shaped guide plate increases the contact area between the material inlet and the crispy shell tube, thereby improving the stability of the crispy shell tube within the material inlet. Example 6

[0069] This embodiment provides a method for preparing a large-headed crispy cone. Milk is poured into the crispy cone and then quickly frozen. The outer coating material is attached to the large-headed surface of the crispy cone using the outer coating material attachment device described in any of the above embodiments. The cone is then quick-frozen, inkjet-coded, packaged, and inspected to become the finished product.

[0070] The material application method of the external coating application device is as follows:

[0071] The material loading mechanism near the first drive component of the device is the feeding area, and the material loading mechanism near the second drive component is the unloading area. The crispy tube after being filled with milk and quick-frozen is placed in the feeding port on the material loading plate.

[0072] When the material carrier plate is delivered to the position of the first drive assembly, the chain circulation mechanism stops conveying, and the first drive assembly controls the pin of the pin assembly to insert the pin into the crispy tube and fix the crispy tube.

[0073] The chain circulation mechanism continues to convey material until the material plate is delivered directly above the hanging mechanism. At this time, the crispy tube is inverted with its large end facing down. The material box of the hanging mechanism is then lifted to allow the large end of the crispy tube to enter the material box to a certain depth, thus completing the coating of the material on the surface of the large end of the crispy tube.

[0074] After the outer material of the crispy shell tube is finished, the chain circulation mechanism continues to send the material loading mechanism to the position of the second drive component and then stops conveying. The second drive component controls the pin insertion component to pull the pin out of the crispy shell tube, and the crispy shell tube is released from the fixed state.

[0075] After the crispy shell tube is released from its fixed state, it is conveyed to the unloading area, removed, and then the subsequent processes continue.

[0076] In the above preparation method, the external material includes one or more combinations of slurry, powder, and granules, wherein: the slurry includes chocolate, the powder includes shredded coconut, and the granules include crushed peanuts and crushed coconut flakes.

[0077] In the above preparation method, the expansion rate of the milk material is 130%~140%, the filling temperature is ≤-3.5℃, the height of the milk material for latte art is 5~5.5cm, and the diameter of the latte art is 6±0.5cm;

[0078] In the above preparation method, both the inner and outer surfaces of the crispy tube are coated with chocolate. The coating temperature of the chocolate is 38~43℃. The chocolate coating is of uniform thickness and completely covers the crispy tube without any white showing. The chocolate sinks to the bottom at a depth of no more than 1cm.

[0079] It is worth noting that sensors are installed next to the two actuators of the first and second drive components. After the sensors detect that the loading mechanism is in place, they send a signal to the actuator, and the control system controls the actuator to push the connecting rod.

[0080] Similarly, a sensor is also installed next to the material hanging mechanism. After the material loading mechanism is in place, it sends a signal to the material hanging mechanism, which then lifts the material box.

[0081] When a material loading mechanism is located directly above the hanging mechanism, the material loading mechanism will reach the operating position of the first drive component and the second drive component.

[0082] The control method of this invention is automatic control by a control system.

[0083] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
