Description

Technical Field

[0001] This utility model belongs to the technical field of yeast trays, specifically relating to an automatic transfer and flipping tray for yeast with embedded reinforcing ribs. Background Technology

[0002] Daqu (a type of starter culture) is a crucial material for traditional solid-state fermentation and distillation of Daqu liquor. As the saying goes, "Daqu is the bone of liquor," and "Good liquor must have good Daqu." The quality of Daqu is closely related to the production of flavor compounds, the formation of style, and changes in quality of Baijiu. Daqu contains a naturally selected and domesticated microbial system that has undergone enrichment, cultivation, and training, providing a source of microbial strains for the multi-strain fermentation of Daqu liquor. The metabolic activity of these microorganisms results in Daqu containing abundant flavor compounds and their precursors. These flavor compounds constitute the unique "Daqu aroma." Daqu is also a complex enzyme preparation, containing various enzyme systems such as amylase, saccharifying enzymes, alcoholic enzymes, esterifying enzymes, and proteases, providing catalysts for the formation of complex aroma components. The traditional Daqu-making process includes ingredient preparation, brick making, and fermentation. The fermentation process refers to the process where, after the Daqu blocks are manually treaded or mechanically pressed into shape, they are transported by the maker to a designated fermentation room and placed on racks or piled on the ground for natural inoculation and fermentation. During the cultivation of Daqu (a type of starter culture), turning the starter is achieved by manually swapping the positions of the starter blocks upside down and left and right. This process is labor-intensive, involves harsh environments (temperatures in the starter room can reach 40 to 60°C), and has low efficiency. It is difficult to achieve the requirements of uniform quality of finished starter blocks and low breakage rate, which restricts the improvement of Daqu production and quality.

[0003] A pallet for automatic transfer and flipping of large gluten blocks, with publication number CN213110210U, can meet the height requirements of different large gluten blocks by adjusting the height of the pallet support columns; it can adapt to the thickness and length requirements of different large gluten blocks by adjusting the diameter of the positioning grids; it can be used on both sides, and the positioning grids are installed in a symmetrical structure, allowing for use from both top and bottom; the ventilation holes adopt an L-shaped alternating or spaced hollow structure to ensure that both sides have sufficient contact area with the large gluten blocks and avoid damage to the blocks; however, it still has the problem of insufficient strength, resulting in plastic deformation after long-term use, and the load capacity and service life of the pallet are relatively limited. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic transfer and flipping tray for large curved beams with embedded reinforcing ribs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic transfer and flipping pallet for large curved surfaces with embedded reinforcing ribs, comprising a pallet body, ventilation holes provided on the pallet body, column holes provided at the four corners and center of the pallet body, reinforcing rib holes provided on the side of the pallet body, and reinforcing ribs provided in the reinforcing rib holes.

[0006] Preferably, three reinforcing rib holes are provided in a "Sichuan character" shape and penetrate from one side of the tray body to the other side.

[0007] Preferably, four reinforcing rib holes are provided and divided into two groups, with two in each group, and the two groups are perpendicular to each other to form a "well" shape.

[0008] Preferably, the reinforcing ribs in the two groups of mutually perpendicular reinforcing rib holes are interpenetrated with each other.

[0009] Preferably, a clamping hole is further provided on the tray body.

[0010] Preferably, the clamping hole is square.

[0011] Preferably, a clamping groove is provided at the bottom of the clamping hole.

[0012] Preferably, the cross-sectional shape of the side surface of the ventilation hole is L-shaped.

[0013] Technical effects and advantages of the present utility model: For the tray for automatically transporting and flipping large qu, with embedded reinforcing ribs, by embedding reinforcing ribs of 304 stainless steel pipes inside the tray, the mechanical properties of the structure are strengthened, the problem of bending deformation of the tray during long-term use is avoided, and moreover, the service life and bearing capacity are improved.

[0021] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other. Embodiment

[0022] The present utility model provides a tray for automatically transporting and flipping large - scale koji, with embedded reinforcing ribs, as shown in Figure 1-5 , which includes a tray main body 1. Ventilation holes 6 are provided on the tray main body 1. The cross - sectional shape of the side of the ventilation hole 6 is L - shaped (such as the shaded part in Figure 5 ). This can ensure a large air - contact area and avoid the koji blocks sinking in due to too small support area at the position of the ventilation hole 6. Column holes 3 are provided at the four corners and the center of the tray main body 1. Reinforcing rib holes 2 are provided on the side of the tray main body 1, and reinforcing ribs are arranged in the reinforcing rib holes 2.

[0023] Three reinforcing rib holes 2 are arranged in a "Sichuan character" shape, and penetrate from one side of the tray main body 1 to the other side. The reinforcing rib holes 2 are square, and are matched with square reinforcing ribs. The reinforcing ribs are made of food - grade 304 stainless steel pipes to increase the overall strength.

[0024] The tray main body 1 is also provided with clamping holes 4. The clamping holes 4 are square. A clamping groove 5 is provided at the bottom of the clamping hole 4. A clamping part is clamped in the clamping hole 4. The clamping part is used for fixing and limiting the koji blocks; the clamping groove 5 is adapted to the protrusions on the clamping part, and the protrusions are stuck in the clamping groove 5. Embodiment

[0025] As shown in Figure 6 , based on the first embodiment, the three "Sichuan character" - shaped reinforcing rib holes 2 are replaced with four "well character" - shaped ones, and are divided into two groups, with two in each group. The two groups are perpendicular to each other to form a "well" character; the two groups of reinforcing ribs have different thicknesses, and the thinner reinforcing ribs pass through the thicker ones, solving the overlapping problem at the intersection of the "well" character.

[0026] During the injection molding process of the reinforcing ribs, before the mold is closed, the stainless steel pipes are placed in the reserved positions of the mold, and then the mold is closed for injection molding. After demolding, the steel pipes are perfectly embedded in the tray.

[0027] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above - mentioned embodiments are exemplary and cannot be construed as a limitation to the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above - mentioned embodiments within the scope of the present utility model.
