[0030] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0031] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0032] It should be noted that the directional terms such as "upper," "lower," "left," "right," "top," "bottom," and "side" described in the following embodiments of this application are merely for facilitating understanding of the coating structure and food coating machine provided in the embodiments of this application. They are not intended to limit the technical solutions of this application.

[0033] First, let’s explain the terms involved in this application:

[0034] Food coating machine: refers to a device that processes raw materials such as chocolate blocks or bars into a slurry suitable for coating through a series of processes such as preheating, stirring, grinding, and filtering, and then evenly coats the slurry on foods of various shapes, sizes, and flavors.

[0035] Coating trough: refers to the container used to hold slurry on the food coating machine.

[0036] Material waterfall curtain: refers to the slurry forming a continuous waterfall-like material layer under the action of gravity.

[0037] White coating: refers to the fact that the food to be processed is not completely covered with a layer of slurry, and part of the product is still exposed.

[0038] Figure 1 This is a schematic diagram of the overall structure of a coating tank in a traditional food coating machine provided in an embodiment of the present application.

[0039] like Figure 1 As shown, the coating trough of a traditional food coating machine has a right-angled edge at the bottom of the surface membrane where the material flows to form a material waterfall. The right-angled edge is generally formed by stamping, welding or bending. Therefore, the welding points, stamping points or bending stress deformation points in the right-angled edge processing process will cause the surface forming the material waterfall to not be completely straight.

[0040] Therefore, when the material flows over the right-angled edge, it will cause the material waterfall to break up, especially for some fluids containing particles, such as chocolate liquid or milkshake liquid. The right-angled edge of the coating trough may cause the material flow rate to be uneven during the formation of the material waterfall, resulting in the material waterfall curtain being broken up. This directly affects the integrity of the material coating on the product surface, resulting in white spots on the coating, and thus poor coating quality of the final product.

[0041] The present application provides a coating structure and food coating machine for a food coating machine, which sets an arc surface at the bottom of the material flow surface of the coating trough of the coating machine to balance the material flow rate before forming the material waterfall curtain, so as to form a complete material waterfall, avoid product coating and whitening, and thus ensure the coating effect of the final product.

[0042] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0043] Example 1

[0044] Figure 2 This is a schematic diagram of the overall structure of a coating structure for a food coating machine provided in this application, such as Figure 2 As shown, the coating structure for the food coating machine includes: a material trough 11, a coating forming plate 12 arranged at the bottom of the material flow surface on both sides of the material trough 11, and a coating adjusting member 13 arranged on the coating forming plate 12.

[0045] The coating adjustment member 13 forms a downwardly curved arc surface at a position away from the side of the material trough 11, and the arc surface is configured to be an arc surface bent away from the coating forming plate 12, so that the arc surface will form a complete material waterfall curtain when the material flowing through under the action of gravity passes through.

[0046] In this embodiment, the material trough 11 can be a trough-shaped container made of stainless steel, and the material trough 11 can be manufactured by welding, stamping, or bending. When in use, the material trough 11 is installed on the food coating machine along the width direction of the food coating machine, and the length direction of the material trough 11 is perpendicular to the conveying direction of the product to be coated on the food coating machine.

[0047] In an optional embodiment of the present application, the material trough 11 is a narrow overflow coating trough.

[0048] In traditional coating troughs, material flows through slits on the sides of the bottom of the trough, with baffles added to adjust the gaps to form a material waterfall, which fully coats the product to be coated. However, when the material contains particles, it is easy for the gaps to become clogged, causing the material waterfall to break and leaving the coated product exposed. In the embodiments of the present application, the narrow, overflow coating trough replaces the slit coating process with an overflow process, avoiding the problem of the material waterfall being interrupted by particles in the material.

[0049] In this embodiment, the coating forming plate 12 can be a folded edge, a plate body or a right-angle structure formed at the bottom of the material flow surface on both sides of the material trough 11 when the material trough 11 is manufactured by welding, stamping or bending.

[0050] In this embodiment, when the material overflows from the top of the material trough 11, the material will first flow slowly downward along the material flow surface on both sides of the material trough 11 under the action of gravity. If there is no coating adjustment part 13 at this time, then when encountering the coating forming plate 12, the flow rate of the material will slow down for the first time, reaching the first flow rate balance of the material movement.

[0051] The coating adjustment member 13 can be arranged on the coating forming plate 12 in a manner of snap-fitting or interference fitting with the material trough 11 .

[0052] Figure 3 Schematic diagram of the structure of the coating adjustment member 13 and the material tank 11 provided in the embodiment of the present application Figure 1 .

[0053] like Figure 3 As shown, in an optional embodiment of the present application, the coating adjustment member 13 is a cylinder, the coating adjustment member 13 is fixedly connected to the material trough 11, and the surface of the material trough 11 and the surface of the coating forming plate 12 are both in contact with the coating adjustment member 13.

[0054] In this embodiment, Figure 3 As shown, there are two coating adjustment members 13 and two coating forming plates 12 , which are arranged at the bottom of two material flow surfaces of the material trough 11 .

[0055] In this embodiment, the coating adjustment member 13 can be a round rod made of stainless steel or other alloy materials, and the coating adjustment member 13 and the material trough 11 can be fixedly connected by bolt connection or interference fit.

[0056] In this embodiment, the surface of the material trough 11 and the surface of the coating forming plate 12 are both in contact with the coating adjusting member 13, which means that when the cylindrical coating adjusting member 13 is placed on the coating forming plate 12, it is also attached to the material flow surface of the material trough 11.

[0057] Specifically, in an optional embodiment of the present application, material baffles 111 are provided on opposite sides of the material trough 11 , and both ends of the coating adjustment member 13 are fixedly connected to the two material baffles 111 respectively.

[0058] In an optional embodiment of the present application, both ends of the coating adjustment member 13 are fixedly connected by any one of bolt connection, clamping, bonding, adsorption or interference fit.

[0059] In this embodiment, the coating adjustment member 13 is fixedly connected to the material baffle 111 by any of bolt connection, clamping, bonding, adsorption or interference fit, in order to facilitate the removal of the coating adjustment member so as to clean the entire coating structure.

[0060] Based on the above embodiment, in an optional embodiment of the present application, the width of the coating forming plate 12 is 12 mm, and the diameter of the coating adjusting member 13 is in the range of [8 mm, 12 mm].

[0061] In this embodiment, the width of coating-forming plate 12 is 20 mm, and coating-adjusting member 13 is a round rod with a width range of 8 mm or greater and less than 12 mm. This allows the material to achieve secondary flow velocity balance on coating-forming plate 12 after flowing through coating-adjusting member 13, thus preventing flow interruption caused by flow imbalance.

[0062] After continuous practice and adjustment by the inventor, in an optional embodiment of the present application, when the coating adjustment member 13 is an 8 mm round rod, the material waterfall curtain formed has a better effect. When the coating adjustment member 13 is larger than 12 mm, such as a 20 mm round rod, the material waterfall curtain will be interrupted, or when the coating adjustment member 13 is smaller than 8 mm, such as a 7.5 mm round rod, the material waterfall curtain will be interrupted, resulting in the inability to form a complete material waterfall curtain. Therefore, if Figure 3 The coating adjustment element 13 used in the embodiment shown has a diameter of 8 mm.

[0063] Example 2

[0064] Figure 4 Schematic diagram of the structure of the coating adjustment member 13 and the material tank 11 provided in the embodiment of the present application Figure 2 .

[0065] like Figure 4 As shown, in an optional embodiment of the present application, the coating adjustment member 13 is a rod body, and the line segment away from the coating forming plate 12 in the cross-sectional diagram of the rod body of the coating adjustment member 13 is an arc. The coating adjustment member 13 is fixedly connected to the material trough 11, and the surface of the material trough 11 and the surface of the coating forming plate 12 are both in contact with the coating adjustment member 13.

[0066] In this embodiment, the rod body can be an arc-shaped rod body in a cross-sectional diagram away from the coating forming plate 12, that is, the surface of the coating adjusting member 13 away from the coating forming plate 12 can be an arc surface. For example, the cross-sectional diagram of the coating adjusting member 13 can be a 90-degree sector.

[0067] like Figure 4 As shown, in this embodiment, the surface of the material trough 11 and the surface of the coating forming plate 12 are both in contact with the coating adjustment member 13, which means that the two side surfaces of the coating adjustment member 13 are respectively placed in contact with the material flow surfaces of the coating forming plate 12 and the material trough 11.

[0068] In an optional embodiment of the present application, material baffles 111 are provided on opposite sides of the material trough 11 , and both ends of the coating adjustment member 13 are fixedly connected to the two material baffles 111 respectively.

[0069] In an optional embodiment of the present application, both ends of the coating adjustment member 13 are fixedly connected to the two material baffles 111 by means of bolt connection, clamping, bonding, adsorption or interference fit.

[0070] In this embodiment, the connection method between the coating adjustment member 13 and the material baffle 111 is similar to that in Example 1, so it will not be described again in this embodiment.

[0071] Example 3

[0072] Figure 5 Schematic diagram of the structure of the coating adjustment member 13 and the material tank 11 provided in the embodiment of the present application Figure 3 .

[0073] like Figure 5 As shown, in an optional embodiment of the present application, the coating adjustment member 13 is an arc-shaped plate, the coating adjustment member 13 is fixedly connected to the material trough 11, the arc surface of the coating adjustment member 13 forms an arc in the direction away from the coating forming plate 12, and the surface of the material trough 11 and the surface of the coating forming plate 12 are both in contact with the coating adjustment member 13.

[0074] In this embodiment, in order to facilitate the installation and placement of the curved plate, the coating adjustment member 13 is configured as a curved plate with an arc angle of 90 degrees.

[0075] In an optional embodiment of the present application, material baffles 111 are provided on opposite sides of the material trough 11 , and both ends of the coating adjustment member 13 are fixedly connected to the two material baffles 111 respectively.

[0076] In an optional embodiment of the present application, both ends of the coating adjustment member 13 are fixedly connected to the two material baffles 111 by means of bolt connection, clamping, bonding, adsorption or interference fit.

[0077] In this embodiment, the connection method between the coating adjustment member 13 and the material baffle 111 is similar to that in Example 1, so it will not be described again in this embodiment.

[0078] Example 4

[0079] Figure 6 Schematic diagram of the structure of the coating adjustment member 13 and the material tank 11 provided in the embodiment of the present application Figure 4 .

[0080] like Figure 6 As shown, in an optional embodiment of the present application, the angle formed between the coating forming plate 12 and the material flow surface of the material trough 11 is in the range of [90°, 180°.

[0081] In this embodiment, in order to facilitate subsequent cleaning of the coating forming plate 12 , the angle formed between the coating forming plate 12 and the material flow surface of the material trough 11 is set to be greater than or equal to 90 degrees and less than 180 degrees.

[0082] The angle range is set to [90°, 180°, which can reduce the processing difficulty when processing the material trough 11 to form the coating forming plate 12, and there is no need to ensure that the coating forming plate 12 is completely perpendicular to the material flow surface of the material trough 11 during welding or bending.

[0083] In summary, the coating structure for a food coating machine provided in the embodiment of the present application is achieved by providing a coating adjustment member 13 on the coating forming plate 12, and forming a downwardly curved arc surface on the coating adjustment member 13 at a position away from the side of the material trough 11. The arc surface is configured to be an arc surface bent away from the coating forming plate 12, so that the arc surface forms a complete material waterfall curtain when the material flowing through it under the action of gravity flows. When the material overflowing from the material trough 11 passes through the arc surface on the coating adjustment member 13 before reaching the cross section forming the waterfall curtain, the secondary flow velocity balance of the material flow is achieved, forming a complete waterfall curtain, completing the material coating of the product to be coated, avoiding the problem of coating whitening during the material coating process, and ensuring the coating effect of the final product.

[0084] At the same time, the coating adjustment part 13 is provided to reduce the processing requirements of the coating forming plate 12, so that during the processing and manufacturing of the material trough 11, whether it is welding or bending, there is no need to ensure that the material flow surface of the coating forming plate and the material trough 11 is perpendicular.

[0085] At the same time, by setting the coating adjustment part 13, the processing difficulty of the coating forming plate 12 is reduced. There is no need to ensure that the coating forming plate 12 is perpendicular to the material flow surface. It can also facilitate the subsequent disassembly and cleaning of the coating adjustment part 13 and the coating forming plate 12, providing convenience for the subsequent maintenance of the coating mechanism.

[0086] At the same time, by only providing the coating adjustment member 13 , there is no need to make large-scale equipment improvements to the entire coating machine or the material tank 11 , thereby saving a lot of equipment modification costs and labor costs, saving time and effort.

[0087] An embodiment of the present application further provides a food coating machine, comprising a coating machine main structure and a coating structure for the food coating machine such as any of the above embodiments installed on the coating machine main structure.

[0088] To facilitate those skilled in the art to understand the present application, the implementation principles of the food coating machine provided in the above embodiments of the present application are as follows:

[0089] First, start the food coating machine and move the product to be coated on the conveyor belt toward the material trough 11. At the same time, continuously inject flowable material into the material trough 11 to fill the entire material trough 11. As the material is continuously injected, the material flows downward along the material flow surfaces on both sides of the material trough under the action of gravity to form a preliminary material waterfall curtain.

[0090] As the material continues to flow downward and encounters coating adjustment member 13, its flow rate slows there, allowing subsequent material to continue and preventing interruptions. After flowing over the curved surface of coating adjustment member 13, the material continues to flow onto coating forming plate 12 and then downward, forming a complete material waterfall. This material waterfall evenly lands on the product to be coated on the conveyor belt passing below material trough 11, completing the coating operation.

[0091] It should be noted that the coating structure for a food coating machine and the materials used in the food coating machine provided in the embodiments of the present application are not particularly limited. However, the inventors have discovered that, particularly when the material contains particulate matter, such as oatmeal or sesame particles in chocolate liquid, the food coating machine provided in the embodiments of the present application can achieve a better coating effect on the coated product.

[0092] Finally, it should be noted that those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the technical solutions disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. It is not limited to the precise structure described above and shown in the drawings, and various modifications and changes may be made without departing from the scope of this application. The scope of this application is limited solely by the appended claims.
