Description

Technical Field

[0001] The utility model relates to a mould, in particular to a winemaking koji block pressing mould used in winemaking technology. Background Art

[0002] Koji making is a crucial step in the winemaking process. Koji making involves preparing the raw materials (wheat, barley, peas, etc.) for the koji blocks. After removing impurities, the raw materials are moistened and crushed. The crushed koji blocks are then mixed with water according to a calculated ratio. The koji and water are then mixed and pressed into blocks using a koji-making device. The modern winemaking industry currently utilizes mechanical koji-making equipment. This equipment compacts the koji blocks, which are fed into molds on an assembly line, into a cubic shape through several pressing cycles. The pressed blocks are then sent to the fermentation chamber for fermentation.

[0003] In the patent document of the Chinese Patent Database with application number CN202010549752.9 and titled "A koji briquetting machine", a conveying mechanism for conveying koji bulk material is provided in the frame, and a plurality of evenly distributed rectangular mold frames for holding koji bulk material are provided on the conveying mechanism, and the rectangular mold frames are movably connected to the conveying mechanism. A bottom plate is provided above the frame, and the bottom plate and the rectangular mold frames form a semi-sealed structure. It can be seen that ordinary koji blocks are all rectangular parallelepiped. The koji blocks are inevitably bumped during transportation or fermentation. The four corners of the rectangular koji blocks are easily damaged by bumps. In severe cases, the entire koji block is damaged, which increases the difficulty of transporting and storing the koji blocks. In addition, the outer surfaces of the ordinary cubic koji blocks are all planes. When the outer perimeter size is constant, the area of ​​the plane is the smallest. Properly increasing the surface area of ​​the koji blocks without changing the outer shape of the koji blocks can effectively increase the contact area between the koji blocks and the air during the fermentation process and improve the fermentation efficiency. The geometric shape of the curved block is determined by the pressing die. To improve the geometric shape of the curved block, the pressing die must be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a brewing koji block pressing mold which is not easy to be damaged and is conducive to improving the fermentation efficiency in view of the shortcomings of the existing technology.

[0005] The problem described in this utility model is solved by the following technical solutions:

[0006] A brewing koji block pressing mold comprises a koji block mold and a pressing upper mold. The pressing mold is a frame structure, and the four inner corners of the frame are smoothly transitioned by inner corner arc surfaces. A pressing surface is provided at the lower part of the pressing upper mold, and the contour of the pressing surface matches the inner circumference contour of the koji block mold.

[0007] The above-mentioned brewing koji block pressing mold, the pressing surface of the pressing upper mold is a concave uniformly distributed hemispherical surface or an undulating wave pressing surface.

[0008] The above-mentioned brewing koji block pressing mold has guide plates arranged around the pressing upper mold, the guide plates are provided with inclined guide surfaces, and a clearance groove is provided between the guide plates and the pressing surface, and the clearance groove corresponds to the pressing mold.

[0009] The arc radius of the inner corner arc surface of the above-mentioned brewing koji block pressing mold is 15-40 mm.

[0010] The present utility model comprises a press-forming upper die and a block mold. The outer contour shape and size of the press-forming upper die and the block mold are matched in the upper and lower directions. The four corners of the block mold are smoothly transitioned by arc surfaces. The block produced by the above structure can effectively reduce the risk of damage to the corners of the block and reduce the difficulty of loading and unloading the block during transportation. The working surface of the press-forming upper die is improved to a hemispherical arc surface or a wavy surface. Under the condition of a certain outer peripheral size, the surface area of ​​the block can be increased by replacing the plane with a curved surface, thereby increasing the contact area between the block and the air during the fermentation process and improving the fermentation efficiency. In addition, a guide plate is added to the press-forming upper die to ensure the accuracy of the press-forming position. The present utility model is easy to manufacture and is suitable for promotion and use in various wine-making enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] See Figure 1-Figure 3The brewing koji block pressing mold described in the present invention includes a koji block mold 6 for holding koji material and a pressing upper mold 2, and the top of the pressing upper mold is connected to a pressing cylinder 1. The koji block mold is transported to the upper part of the pressing platform 8 by a conveyor belt 7. The koji block mold 6 is a frame structure, and the four inner corners of the frame are smoothly transitioned by the inner corner arc surface 6-1, and the arc radius of the inner corner arc surface is 15-40 mm. A pressing surface 3 that directly contacts the koji material is provided at the lower part of the pressing upper mold, and the peripheral contour of the pressing surface matches the inner peripheral contour of the koji block mold. The above structure can make the koji block have four rounded corners after pressing, effectively reducing the risk of damage to the corners of the koji block.

[0017] See Figure 1 、 Figure 3 The pressing surface of the pressing upper die of the present invention is designed as a concave arc pressing surface 3, an undulating wave pressing surface 9, or a uniformly distributed hemispherical surface. Both of these non-planar pressing surface structures can increase the area of ​​the upper surface of the block 10 under the premise of a certain outer dimension of the block, thereby increasing the contact area between the block and the air during the fermentation process and improving the fermentation efficiency. The upper die structure with an arc pressing surface is relatively simple. During the fermentation process, the block is placed upright with one long side as the bottom. The convex arc surface is easy to cause it to sink, and the stability of the block placement is slightly poor. The wave pressing surface does not sink when placed upright and has good stability, but the upper die structure is relatively complex.

[0018] Still see Figure 1 、 Figure 3 To improve profiling accuracy, guide plates 5 are provided around the upper die, each with an outward-inclined guide surface 5-1. To prevent interference between the upper die and the curved block mold during the profiling process, which could affect the compaction effect, recesses 4 are provided between the guide plates and the profiling surface. These recesses correspond to the four outer walls of the profiling die, and their widths are greater than the wall thickness of the die.
