Description

Technical Field

[0001] The present invention relates to the technical field of food processing equipment, and more particularly to a food tray. Background Art

[0002] In the food processing industry, flower-shaped sausage-like foods such as flower-shaped sausages (ear-shaped sausages) are deeply loved by consumers because of their unique appearance and taste. Existing flower-shaped sausages generally have a number of openings pre-cut on the outer surface of the sausage. During the process of high-temperature frying or grilling after consumers purchase them, the openings naturally turn outwards and curl to form "sausage flowers", which are relatively beautiful in appearance and are also relatively easy to be flavored when brushing seasonings.

[0003] Taking flower-shaped sausages as an example, for the convenience of consumers' processing, there is a kind of flower-shaped sausage that is pre-formed with a flower-shaped appearance after being cut and then subjected to high-temperature steaming before being sold, and then packaged and sold. Such products usually need to go through two steaming processes to achieve an ideal degree of maturity and appearance effect. Generally, the width after the second steaming "flowering" can usually reach 1.8 to 2.2 times that before steaming.

[0004] However, in the existing steaming process, when flower-shaped sausages are subjected to the second steaming, it is easy to cause uneven steaming environment due to unreasonable design of the steaming tray, and the distance between the sausages is too close, resulting in insufficient heating or insufficient space for flowering, resulting in inconsistent appearance color or insufficient "flowering" of the product, affecting the quality of the finished product.

[0005] Moreover, due to the irregular shape of the flower-shaped sausage itself, in mass production, to form and maintain the "flowering" shape, special containers are required for processing and placement to avoid the situation of insufficient, irregular or non-"flowering" due to container extrusion, resulting in shape deformation or damage, reducing the market competitiveness of the product; in addition, when the sausage is not "flowering", it is cylindrical in shape and has skewers inserted, and there is a situation of rolling. If it cannot be fixed well, it will also affect the "flowering" effect. Summary of the Invention

[0006] The purpose of the present invention is to provide a food tray, which is suitable for the steaming and processing of strip-shaped foods that need to expand and deform after steaming. In the following text, taking the processing of sausages into flower-shaped sausages as an example, the sausage can be replaced by any strip-shaped food that needs to expand and deform after steaming.

[0007] To achieve the above-mentioned objectives, the present invention provides a food tray, in which the food is in the shape of an elongated strip, with a skewer passing through the middle of the food, comprising: a rectangular outer frame, a grid structure within the outer frame, and a mounting assembly spanning the outer frame and standing on the grid structure, with an angle formed between the mounting assembly and the grid structure; a plurality of ventilation holes are arrayed in the grid structure, the mounting assembly comprises a mounting plate, a positioning groove and an avoidance groove are recessed downward on the upper edge of the mounting plate, the positioning groove and the avoidance groove are alternately arranged, and when the food is placed on the food tray, the skewer passing through the food is limited on the positioning groove and / or the avoidance groove of the mounting plate, and the other end of the food is supported on the grid structure, so that an inclined angle is formed between the food and the skewer and the food tray.

[0008] Furthermore, the mounting assembly includes a pair of mounting plates, wherein the positioning groove of one mounting plate corresponds to the avoidance groove of the other mounting plate, and the same stick is mounted in the positioning groove and the corresponding avoidance groove at the same time.

[0009] Furthermore, the positioning groove is an isosceles triangle with the top corner facing downward, and the avoidance groove is an isosceles trapezoid, V-shaped or U-shaped with the upper base facing downward, and the positioning point of the stick in the positioning groove is located in front of the positioning point of the stick in the avoidance groove.

[0010] Furthermore, both ends of the mounting plate are rotatably connected to the outer frame through a connecting piece, and the connecting piece has a connecting slot block and an adjustment piece connected to one side of the connecting slot block. The connecting slot block is installed on the outer frame, and the adjustment piece is located on the inner side of the outer frame. The adjustment piece is provided with at least one angle adjustment hole. Connecting pieces are respectively provided at both ends of the mounting plate, and the connecting pieces are provided with mounting holes. The pin passes through the mounting hole and one of the angle adjustment holes to lock the mounting plate on the connecting piece. The angle change of the mounting plate relative to the outer frame can be achieved by selecting different angle adjustment holes.

[0011] Furthermore, the connecting piece is detachably connected to the outer frame, the connecting slot block covers the outer frame and is fixed by screws, and the connecting piece can be detached and installed in a repositioned manner on the outer frame.

[0012] Furthermore, the angle adjustment holes on the same adjustment plate are arranged at intervals, and after the connecting plate is connected to the different angle adjustment holes, the angles between the connecting plate and the grid structure are different.

[0013] Furthermore, the grid structure includes a plurality of stainless steel wires in a sinusoidal waveform, both ends of each stainless steel wire are respectively fixed on the outer frame, and the transverse and longitudinal stainless steel wires are orthogonally woven to form the grid structure.

[0014] Furthermore, the outer frame is divided into two parts from the center by a partition rod, and each part is provided with a set of erection components, and the erection components are located in the center of each part.

[0015] Furthermore, the outer frame is formed by enclosing stainless steel bars with square cross sections, and the four corners of the outer frame are provided with arc transition corners.

[0016] Further, the positioning groove is an isosceles triangle with a height of 25 mm and an apex angle of 85°; the avoidance groove is an isosceles trapezoid with a height of 20 mm, an upper base length of 4 mm, and a lower base length of 6 mm.

[0017] After adopting the above solution, the present invention has at least the following technical effects: 1. When it is necessary to fix the sausage on the food tray, the skewer passing through the tail end of the sausage is placed in the positioning groove and / or avoidance groove of the erection plate, and the head end of the sausage is supported on the grid structure, reducing the contact area between the sausage and the food tray, improving the effect of uniform heating and shaping of the blooming sausage during the steaming process, enabling the middle section of the sausage to "bloom" evenly without obstruction during heating, avoiding deformation or breakage of the sausage caused by uneven heating, and forming a blooming sausage with a better effect.

[0018] 2. A large number of sausages can be neatly placed on the food tray and heated simultaneously, optimizing the placement efficiency and steaming efficiency, and ensuring the consistency of the appearance and quality of the blooming sausage, which is suitable for industrial food processing production lines.

[0019] 3. The setting of the grid structure can not only make the sausage heated evenly but also provide space for the sausage to "bloom". BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0026] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0027] See Figure 1 、 Figure 2 The figure shows an embodiment of the present invention, which provides a food tray suitable for steaming and processing strip-shaped foods that require expansion and deformation during cooking. The processed foods are typically long strips, with a skewer (not shown) inserted through the middle of the food lengthwise and exiting the food at the rear end. The following description uses the example of processing sausages with skewers into flower sausages, but sausages can be substituted for any other strip-shaped food that requires expansion and deformation during cooking.

[0028] This embodiment includes: a rectangular outer frame 1, a grid structure 2 within the outer frame 1, and a mounting assembly spanning the outer frame 1 and standing on the grid structure 2, with an angle formed between the mounting assembly and the grid structure 2; a plurality of ventilation holes 21 are arrayed in the grid structure 2, and the mounting assembly includes a mounting plate 3, with a positioning groove 31 and an avoidance groove 32 recessed downward on the upper edge of the mounting plate 3, the positioning groove 31 and the avoidance groove 32 being alternately arranged, and when the sausage is mounted on the food plate, the skewer that passes through the sausage is limited on the positioning groove 31 and / or the avoidance groove 32 of the mounting plate 3, and the other end of the sausage is supported on the grid structure 2, and an inclined angle is formed between the sausage and the skewer and the food plate.

[0029] In this embodiment, the mounting assembly includes a pair of mounting plates 3 in the form of long strips, the mounting plates 3 are consistent in length with the outer frame 1, the bottom ends of the two mounting plates 3 are parallel to each other, the positioning groove 31 of one mounting plate 3 corresponds to the avoidance groove 32 of the other mounting plate 3, and the same sign is mounted simultaneously in the positioning groove 31 of one mounting plate 3 and the avoidance groove 32 of the other mounting plate 3 corresponding thereto. Specifically, the positioning groove 31 is an isosceles triangle with its vertex facing downward, and the avoidance groove 32 is an isosceles trapezoid with its upper base facing downward. The positioning point of the skewer in the positioning groove 31 is located in front of the positioning point of the skewer in the avoidance groove 32. The positioning groove 31 is supported below the skewer, and the avoidance groove 32 is used to avoid the tail end of the sausage skewer so that the skewer can pass through the mounting plate 3, and can limit the position of the skewer inserted on the sausage to limit the position of the sausage. Therefore, the corresponding positioning grooves 31 and avoidance grooves 32 on the two mounting plates 3 are arranged in a corresponding manner so that the central axis of the isosceles triangle of the positioning groove 31 and the central axis of the isosceles trapezoid of the avoidance groove 32 are on the same straight line (see Figure 5 ).

[0030] It should be noted that, depending on the size of sausages and skewers, not all skewers will fit into the escape groove 32 (the skewers may be tilted and higher than the escape groove 32). Therefore, the escape groove 32 only serves to prevent the skewers from passing through the second mounting plate 3 and to limit their position when the skewers fit into the escape groove 32. In other embodiments, the escape groove 32 may also be V-shaped or U-shaped.

[0031] When performing the secondary steaming of the blooming sausage, the strung sausages are placed on the food tray of this embodiment manually or mechanically. On a mounting component, two columns of sausages are respectively placed on the left and right sides along the length direction. The head end of the first column of sausages faces the left side of the left mounting plate 3 and abuts against the grid structure 2. The middle section of the skewer passing through the sausage (here, the middle section of the skewer refers to the section from the support point of the skewer supported on the avoidance groove 32 to the end of the sausage) is supported in the positioning groove 31 of the left mounting plate 3, and the tail end part of the skewer of the sausage falls into the avoidance groove 32 opposite to the positioning groove 31 of the right mounting plate 3 to form a limit. At this time, the sausage is inclined on the food tray. The head end, the middle section of the skewer, and the tail end part of the first column of sausages are respectively in the grid structure 2, the positioning groove 31 of the left mounting plate 3, and the avoidance groove 32 of the right mounting plate 3; similarly, the head end, the middle section of the skewer, and the tail end part of the second column of sausages are respectively in the grid structure 2, the positioning groove 31 of the right mounting plate 3, and the avoidance groove 32 of the left mounting plate 3. Since the positioning grooves 31 and the avoidance grooves 32 on the mounting plate 3 are alternately distributed, the head end orientations of the adjacent sausages in the front and back rows are opposite, that is, the adjacent sausages in the front and back rows belong to the left and right columns respectively.

[0032] By placing the sausages on the food tray of this embodiment in the above manner, a large number of sausages can be neatly placed on the food tray and heated simultaneously, optimizing the placement efficiency and steaming efficiency; it can also ensure that there is enough space between the sausages and between the sausages and the food tray, so that each sausage can fully "bloom"; and through the setting of the ventilation holes 21 in the grid structure 2, the contact area between the sausage and the food tray is reduced, avoiding deformation or damage of the sausage due to uneven force and uneven heating, ensuring the consistency of the appearance and quality of the product, and being applicable to the industrial food processing production line.

[0033] In addition, this embodiment can accommodate most common sausage sizes. When the diameters of the sausages have different sizes, the middle sections of their skewers can be initially positioned in the positioning grooves 31; and the avoidance groove 32 only needs to limit the tail end part of the skewer, so the width of the avoidance groove 32 is set relatively narrow (the width of the avoidance groove 32 can be set slightly wider than the width of the skewer). After the skewer enters the avoidance groove 32, it cannot swing significantly left and right, or is clamped and fixed as the width of the isosceles trapezoidal avoidance groove 32 gradually narrows downward, so that the middle section of the skewer passing through the sausage is centered and fixed in the positioning groove 31. The sausage placement method of this embodiment (the head end orientations of the adjacent sausages in the front and back rows are opposite, that is, the adjacent sausages in the front and back rows belong to the left and right columns respectively) can itself stagger the placement of the sausages, so that there is sufficient blooming space between the front and back rows of sausages in the same column. When the diameter of the sausage is large, the interval between the front and back rows of sausages in the same column can be further enlarged (for example, leaving more rows of positioning grooves and avoidance grooves vacant between the front and back rows of sausages in the same column), and then placed in the above-mentioned manner.

[0034] Refer to Figure 3 、 Figure 4 In this embodiment, a connecting member 4 is detachably connected to the outer frame 1. The connecting member 4 has a connecting groove block 41 which covers the outer frame 1 and is fixed by screwing. The connecting member 4 is detachably and transversely installed on the outer frame 1. An adjusting piece 42 is further provided on one side inside the outer frame 1. Both ends of the erection plate 3 are rotatably connected to the outer frame 1 through the connecting member 4. Specifically, at least one angle adjusting hole 421 is provided on the adjusting piece 42. Connecting pieces 33 are respectively provided at both ends of the erection plate 3. Mounting holes 331 are provided on the connecting pieces 33. A pin 5 passes through the mounting hole 331 and one of the angle adjusting holes 421 to lock the erection plate 3 on the connecting member 4. By selecting different angle adjusting holes 421, the angle change of the erection plate 3 relative to the outer frame 1 is realized. In this embodiment, three angle adjusting holes 421 are provided on the adjusting piece 42 at intervals. The center line connection of the three angle adjusting holes 421 is arc-shaped. After the connecting piece 33 is fixed to different angle adjusting holes 421, the included angle with the food tray plane (grid structure 2) is different.

[0035] When the blooming sausage has different length dimensions, the angle between the sausage and the food tray can be adjusted by adjusting the angle of the erection plate 3, so that the food tray can be suitable for sausages of different sizes, which is more convenient to use. Further, if only adjusting the angle of the erection plate 3 cannot meet the placement of the sausage, the distance between the two erection plates 3 or the distance between the erection plate 3 and the edge of the food tray (outer frame 1) can be adjusted by disassembling and reinstalling the connecting member 4 to adjust the placement state of the sausage.

[0036] The erection component of this embodiment has two erection plates 3. Both ends of each erection plate 3 are connected to the outer frame 1 through two connecting members 4 respectively. The connecting members 4 at the ends of the left and right erection plates 3 are symmetrically arranged.

[0037] Preferably, a spring 51 is sleeved on the pin 5 of this embodiment. The pin 5 sleeved with the spring 51 penetrates from the outside of the angle adjusting hole 421 and passes through the connecting hole of the connecting piece 33 of the erection plate 3, so that the spring 51 is compressed between the connecting piece 33 and the adjusting piece 42. The spring 51 can play a role in relatively fixing the connecting piece 33 and the adjusting piece 42 to prevent the erection plate 3 from sliding on the pin 5. A perforation is provided at the rear end of the pin 5 passing through the connecting hole. When a locking rod 52 is inserted into the perforation, the pin 5 does not come out of the rear end of the connecting piece 33, thereby locking the connection relationship between the connecting member 4 and the erection plate 3.

[0038] The grid structure 2 of this embodiment includes several stainless steel wires 22 in a sine wave shape. Both ends of each stainless steel wire 22 are respectively fixed on the outer frame 1, and the horizontal and vertical stainless steel wires 22 are orthogonally and staggeredly woven to form the grid structure 2. The structure of the stainless steel wire 22 is uneven on the surface in contact with the sausage, which can further reduce the contact area with the sausage, making the sausage heated evenly and blossom evenly.

[0039] The outer frame 1 of this embodiment is divided into two parts from the center by the partition rod 11, and a set of erection components are respectively arranged on each part. The erection components are located in the center of each part, that is, there are two sets of erection components (four erection plates 3) on one food tray, and at most four rows of blossoming sausages can be placed for simultaneous steaming, with higher production efficiency.

[0040] Preferably, the outer frame 1 of this embodiment is enclosed by square stainless steel bars with a cross-section, and arc transition corners are provided at all four corners of the outer frame 1.

[0041] The dimensions of each part in the food tray of the above embodiment can be configured according to the actual production situation. The specific dimensions that can be adopted in this embodiment are as follows: The outer frame 1 is made of square stainless steel bars with a cross-section of 10mm×10mm. The outer length of the outer frame 1 is 680mm, the outer width is 650mm, which matches the layout of the food cart, and the radius of the arc transition corner at the four corners of the outer frame 1 is 45mm.

[0042] The cross-section of the stainless steel wire 22 for weaving the grid structure 2 is a circle with a diameter of 1mm. The stainless steel wire 22 is in a sine wave shape, with a wavelength of 5mm, an amplitude of 2.5mm, and the center distance between the stainless steel wires 22 that intersect perpendicularly to each other is 20mm.

[0043] In the same set of erection components, the distance between the two erection plates 3 is 14mm. On each erection plate 3: The center distance between the adjacent avoidance groove 32 and the positioning groove 31 is 27.5mm; The positioning groove 31 with an isosceles triangle shape has an isosceles triangle height of 25mm, the angle of the apex angle is 85°, the distance between two adjacent positioning grooves 31 is 55mm, and the vertical height from the lower end point (i.e., the apex) of the positioning groove 31 to the food tray plane is 47.5mm; The avoidance groove 32 with an isosceles trapezoid shape has an upper base length of 4mm, a lower base length of 6mm, a height of 20mm, the distance between two adjacent avoidance grooves 32 is 55mm, and the vertical height from the upper base facing downwards to the food tray plane is 52.5mm.

[0044] The above is only one embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
