Description

Technical Field

[0001] This utility model relates to the field of sterilization device technology, and in particular to a food tray. Background Technology

[0002] As an important piece of equipment in food processing, the autoclave is used to sterilize food at high temperatures. It typically contains multiple layers of trays to hold the food to be sterilized. For example, utility model patent CN205525496U discloses a tray structure specifically designed for autoclaves.

[0003] However, most existing food trays adopt a flat-bottom design, which has significant limitations in practical applications. For example, when multiple trays are stacked, the bottom of the upper tray will directly contact the top surface of the food on the lower tray. This not only hinders the even penetration of steam or other heat media into each layer of food, causing uneven heating and affecting the sterilization effect, but also easily causes softer foods to deform or even break due to pressure, reducing product quality. Utility Model Content

[0004] In view of this, the present invention proposes a food tray, which adopts a grid-like skeleton structure composed of two X-direction perforated plates, multiple Y-direction perforated plates, and multiple X-direction perforated carriers. Each X-direction perforated carrier uses a trapezoidal groove plate with symmetrical upper and lower sections and opposite grooves, so that the food surface is not directly compressed when adjacent trays are stacked. At the same time, the through holes on the plate and the gaps between layers form a multi-directional heat medium flow channel, which effectively solves the technical problems of uneven heating, food deformation and poor stacking stability caused by poor steam circulation and interlayer compression in existing flat-bottomed trays during sterilization.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a food tray, comprising two X-axis perforated plates, multiple Y-axis perforated plates, and multiple X-axis perforated carriers, wherein... Multiple Y-direction perforated plates are fixed between two X-direction perforated plates to form a tray frame; The plurality of X-direction porous carriers and the plurality of Y-direction porous plates are arranged in a grid-like cross pattern; Each of the X-direction porous carriers includes two trapezoidal groove-shaped plates, which are fixed to the Y-direction porous plate, and the plates are evenly distributed with first through holes. The two plates are arranged symmetrically about the horizontal centerline of the Y-direction perforated plate, and the slots of the two plates are opposite to each other.

[0006] Based on the above technical solution, preferably, an avoidance opening is provided on the plate body in the area intersecting with the Y-direction perforated plate, wherein, The Y-axis perforated plate passes through the clearance opening.

[0007] Based on the above technical solutions, preferably, a limit plate is inclinedly provided on the inner side of the clearance opening, wherein, One end of the limiting plate is fixedly connected to the side of the Y-direction multi-hole plate, and the other end is fixedly connected to the bottom end of the groove of the plate body.

[0008] Based on the above technical solutions, preferably, the groove on both sides of the plate body is provided with flanges, wherein... The flange is fixed to the top of the Y-direction perforated plate.

[0009] Based on the above technical solutions, preferably, the top end of the Y-direction perforated plate is horizontally aligned with the top end of the X-direction perforated plate, and the top of the Y-direction perforated plate is provided with a receiving groove, wherein... The flange is embedded in the receiving groove.

[0010] Based on the above technical solutions, preferably, a second through hole is provided on the side of the Y-direction perforated plate and in the area corresponding to the bottom of the plate groove.

[0011] Based on the above technical solutions, preferably, a third through hole is provided on the side of the Y-direction perforated plate and in the area corresponding to the groove wall of the plate.

[0012] Based on the above technical solutions, preferably, a fourth through hole is provided on the side of the X-direction perforated plate at a position corresponding to the groove wall of the plate body.

[0013] Based on the above technical solutions, preferably, a gap is provided between two adjacent plates.

[0014] Based on the above technical solution, preferably, the X-direction perforated plate has a positioning pin at the top and a pin hole at the bottom, wherein... The pin hole is located directly below the locating pin.

[0015] The food tray of this utility model has the following advantages over the prior art: (1) By adopting a grid-like skeleton structure composed of two X-direction perforated plates, multiple Y-direction perforated plates, and multiple X-direction perforated carriers, and setting trapezoidal groove-shaped plates with symmetrical upper and lower sections and opposite slots in each X-direction perforated carrier, a cavity for accommodating food is formed between the two plates with opposite slots in the upper and lower trays when the trays are stacked, thus avoiding the upper tray directly pressing the lower food. At the same time, the through holes on the plates are used to construct multi-directional through-flow channels for the heat medium, which significantly improves the uniformity of steam flow and effectively improves product quality.

[0016] (2) By setting a clearance opening at the intersection of the plate and the Y-direction perforated plate, it is not only convenient for the two to assemble, but also naturally forms a lateral medium channel in the clearance opening area, enhancing the heat medium penetration capability. In addition, an inclined limiting plate is added to the inside of the clearance opening to form a triangular reinforcement structure, which can not only improve the connection strength and torsional performance between the X-direction perforated carrier and the Y-direction perforated plate, but also restrict the lateral sliding of food in the tank, prevent the channel from being blocked by food or packaging, and ensure that the flow path is unobstructed.

[0017] (3) By setting corresponding first through holes, second through holes, third through holes and fourth through holes on the plate body, Y-direction perforated plate and X-direction perforated plate, the entire tray has a hollow structure with high opening rate, which greatly reduces thermal resistance, promotes the all-round penetration of heat medium inside the tray and between layers, achieves uniform heat distribution and excellent heat penetration performance, thereby ensuring the high efficiency and consistency of the sterilization process.

[0018] (4) By maintaining a gap between two adjacent plates, a stable interlayer ventilation channel is formed. Even in the case of multiple layers tightly stacked, steam can still freely pass through each layer of carrier area, effectively avoiding the generation of local "suffocation zone", ensuring that the whole pot of food is heated evenly and sterilized thoroughly, and improving the overall sterilization effect.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0027] like Figure 1-10 As shown, a food tray of this utility model includes two X-direction perforated plates 1, multiple Y-direction perforated plates 2, and multiple X-direction perforated carriers 3.

[0028] The X-direction perforated plate 1 extends along the X direction, and the Y-direction perforated plate 2 extends along the Y direction. Multiple Y-direction perforated plates 2 are fixed at equal intervals between two X-direction perforated plates 1 along the X direction, together forming an integral rigid pallet frame. The X-direction perforated carrier 3 extends along the X direction and is arranged in a grid pattern with multiple Y-direction perforated plates 2 to form regularly distributed food-carrying cells.

[0029] Each X-direction perforated carrier 3 includes two trapezoidal slotted plates 31, which are arranged symmetrically about the horizontal centerline of the Y-direction perforated plate 2, with their slots facing away from each other. The plates 31 are fixed to the Y-direction perforated plate 2 by welding or riveting, and each plate 31 has a first through hole 3101 evenly distributed on it.

[0030] When multiple trays are stacked in the sterilizer, such as Figure 10 As shown, the lower plate 31 of the upper tray and the upper plate 31 of the lower tray have opposite grooves, naturally enclosing each other to form a cavity structure. This cavity structure is used to accommodate packaged or bulk food, effectively preventing the upper tray from directly pressing on the surface of the food below. Simultaneously, the first through hole 3101 on the plate 31 creates a multi-directional heat medium flow channel, significantly improving the uniformity of steam flow, ensuring consistent heating of the food, and improving product quality.

[0031] Furthermore, a clearance opening 3102 is provided on the plate 31 in the area where it intersects with the Y-direction perforated plate 2, through which the Y-direction perforated plate 2 passes. In a top view, the clearance opening 3102 is an isosceles trapezoidal shape to accommodate the cross-sectional shape of the Y-direction perforated plate 2. A limiting plate 32 is inclinedly provided inside the clearance opening 3102. One end of the limiting plate 32 is fixedly connected to the side of the Y-direction perforated plate 2 by welding or riveting, and the other end is fixedly connected to the bottom end of the groove of the plate 31 by welding or riveting.

[0032] In this structure, the clearance opening 3102 on the plate 31 not only facilitates the cross-assembly of the plate 31 and the Y-direction perforated plate 2, but also naturally forms a lateral medium channel in the clearance opening 3102 area, enhancing the penetration capability of the hot medium. Specifically, the design of the clearance opening 3102 allows steam or other hot media to quickly enter and exit from the side of the tray, significantly improving the penetration efficiency of the hot medium to the side of the food and reducing the occurrence of local cold spots.

[0033] In addition, the limiting plate 32 added inside the clearance opening 3102 forms a triangular reinforcement structure, which can not only improve the connection strength and torsional performance between the X-direction perforated carrier 3 and the Y-direction perforated plate 2, but also restrict the lateral slippage of food in the tank, prevent the channel from being blocked by food or packaging, and ensure that the flow path is unobstructed.

[0034] In addition, flanges 311 are provided on both sides of the groove of the plate 31, and the flanges 311 are fixed to the top of the Y-direction perforated plate 2. Specifically, the top of the Y-direction perforated plate 2 is horizontally aligned with the top of the X-direction perforated plate 1, and a receiving groove 201 is provided on the top of the Y-direction perforated plate 2. The flanges 311 are embedded in the receiving groove 201 and are further secured by welding or riveting.

[0035] In this structure, the flange 311 is a horizontal plate-like structure, which is housed in the receiving groove 201. This ensures that the upper surface of the tray is flat, facilitating cleaning and automated operation, while also enhancing the connection reliability between the flange 311 and the Y-direction perforated plate 2, preventing warping.

[0036] To further optimize heat conduction performance, a second through hole 202 is provided on the side of the Y-direction porous plate 2 in the region corresponding to the bottom of the groove of the plate body 31. At the same time, a third through hole 203 is provided on the side of the Y-direction porous plate 2 in the region corresponding to the groove wall of the plate body 31, and a fourth through hole 101 is provided on the side of the X-direction porous plate 1 in the region corresponding to the groove wall of the plate body 31.

[0037] The first through hole 3101, the second through hole 202, the third through hole 203 and the fourth through hole 101 work together to give the entire tray a hollow structure with a high opening ratio, which greatly reduces thermal resistance and promotes the all-round penetration of steam in the tray's interior, interlayer and edge areas, achieving uniform heat distribution and excellent heat penetration performance, ensuring that the sterilization process is efficient and consistent.

[0038] Based on the above structure, a gap is provided between two adjacent plates 31. For example... Figure 7 and Figure 10 As shown, this gap creates a stable interlayer ventilation channel between the upper and lower plates 31. Even under multi-layer tight stacking conditions, steam can still freely pass through each layer of the carrier area, effectively avoiding the generation of local "suffocation zones" and ensuring that the food in the whole pot is heated evenly and sterilized thoroughly.

[0039] Based on this, the X-direction perforated plate 1 has a positioning pin 11 at the top and a pin hole 102 at the bottom, with the pin hole 102 located directly below the positioning pin 11. For example... Figure 10 As shown, when the upper and lower pallets are stacked, the positioning pin 11 of the upper pallet is inserted into the pin hole 102 of the lower pallet to achieve precise alignment, prevent misalignment and slippage, and improve stacking stability and operational safety. It is especially suitable for automated sterilization production lines.

[0040] The method of using a food tray according to this utility model is as follows: First, place the food or food packaging to be sterilized layer by layer on a single tray. Specifically, place the product stably into the trapezoidal slot of the upper plate 31 of the tray.

[0041] After all pallets are loaded, multi-layer stacking is performed: During stacking, the positioning pin 11 of the upper pallet is inserted into the corresponding pin hole 102 of the lower pallet to achieve precise alignment and stable connection between the upper and lower pallets, avoid misalignment, tilting or slippage, and improve stacking safety and automation compatibility.

[0042] After stacking, all trays are placed into the sterilizer for high-temperature sterilization. During this process, the gaps between the plates 31 of adjacent trays, the first through holes 3101 on each plate 31, the second through holes 202 and the third through holes 203 on the Y-direction perforated plate 2, the fourth through hole 101 on the X-direction perforated plate 1, and the lateral channels formed by the clearance openings 3102 together constitute a three-dimensional through-flow network of heat medium, enabling steam to penetrate each layer of food evenly and efficiently, ensuring consistent heating and thorough sterilization, and significantly improving product quality and production efficiency.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
