Description

Technical Field

[0001] The utility model belongs to the technical field of wine-making equipment, and in particular relates to a diamond-shaped hole sieve plate of a cooling machine. Background Art

[0002] The traditional solid-state brewing process of liquor generally includes crushing, batching, mixing, cooking, cooling, adding koji, fermentation, etc. In order to avoid the temperature of the lees after cooking being too high, which will kill too many yeasts when adding koji later, resulting in a decrease in the wine yield and a decrease in the quality of the wine, it is necessary to cool down the lees (including the rice husk in the lees) after rapid cooking. At present, there are two types of sieve holes in the cooling screen plate of the cooling machine, one is round and the other is oblong. Because the diameter of the lees pellets is 6mm and the size of the rice husk is 2×9mm, in order to avoid leakage of lees and rice husks, the maximum size and diagonal size of the oblong sieve holes of the cooling screen plate are required to be designed to be no more than 9mm, and the diameter of the circular sieve holes is designed to be no more than 5mm. However, both sieve holes are prone to sieve hole clogging, which greatly reduces the ventilation effect and affects the cooling of the lees. Utility Model Content

[0003] The utility model aims to solve the above-mentioned deficiencies in the prior art and provide a diamond hole sieve plate for a cooling machine which can improve the ventilation effect and avoid material leakage.

[0004] In order to achieve the above purpose, the technical solution adopted is:

[0005] A diamond hole sieve plate for a cooling machine comprises a metal sieve plate, a connecting piece and a plurality of diamond holes distributed on the metal sieve plate, wherein the connecting piece is used to connect a plurality of metal sieve plates together, and the diamond holes are regular diamonds or waisted diamonds. The sieve holes are designed to be diamond-shaped, and the through hole area is increased in the length direction compared with circular holes, and the through hole area is increased in the width direction compared with long circles, thereby ensuring the ventilation effect.

[0006] As another preferred embodiment of the utility model, the width of the diamond-shaped holes is 1-4 mm and the length is 4-8 mm, so that the maximum size and diagonal size of the sieve holes are sufficient to ensure that 6 mm diameter wine grains and 2×9 mm rice husks will not leak out of the sieve holes.

[0007] As another preferred embodiment of the utility model, the opening area of ​​the diamond holes on the upper surface of the metal sieve plate is smaller than that on the lower surface, so that when the air is heated and rises, a small air pressure difference is formed between the upper and lower surfaces of the diamond holes, thereby increasing the flow of cold air from the lower surface to the upper surface of the diamond holes and accelerating the cooling of the lees.

[0008] As another preferred embodiment of the present invention, the diamond-shaped holes may be arranged in a variety of patterns such as horizontal, vertical, and staggered.

[0009] As another preferred solution of the present invention, the steel belt is made of stainless steel, which is easier to clean and less likely to breed bacteria.

[0010] Compared with the prior art, the diamond-shaped hole sieve plate of the cooling machine provided by the utility model designs the sieve holes into diamond shapes. While ensuring that the grains of distiller's grains and rice husks will not leak out of the sieve holes, the through-hole area is increased in the length direction compared to circular holes, and the through-hole area is increased in the width direction compared to the longer circle, thereby increasing the ventilation effect. By designing the diamond-shaped holes so that the opening area of ​​the upper surface is smaller than the opening area of ​​the lower surface, a slight air pressure difference is formed between the upper and lower surfaces of the diamond-shaped holes, thereby increasing the upward flow of cold air and accelerating the cooling of the distiller's grains.

[0013] In order to better understand the present invention, the specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0014] Example 1

[0015] As attached Figure 1-3 As shown, a diamond hole sieve plate for a cooling machine includes a metal sieve plate 1, a connecting piece 2 and a plurality of regular diamond holes 3 distributed on the metal sieve plate 1. The metal sieve plate 1 is made of stainless steel. The regular diamond holes 3 are 4 mm wide and 8 mm long and are arranged in a staggered pattern. The opening area of ​​the regular diamond holes 3 on the upper surface of the metal sieve plate 1 is smaller than the opening area on the lower surface.

[0016] Example 2

[0017] As attached Figure 4-5 As shown, a diamond-shaped hole sieve plate for a cooling machine has structural dimensions referring to Example 1. The difference from Example 1 is that the through holes on the metal sieve plate 1 are designed as waisted diamond-shaped holes 4.

[0018] Comparative Example

[0019] As attached Figure 6 As shown, a diamond-shaped hole sieve plate for a cooling machine has structural dimensions referring to Example 1. The difference from Example 1 is that the through holes on the metal sieve plate 1 are designed as circular holes 5, the diameter of the circular holes 5 is 5 mm, and the opening areas on the upper and lower surfaces of the metal sieve plate 1 are the same.

[0020] Please refer to Figure 7 The regular diamond holes 3 in Example 1 and the waisted diamond holes 4 in Example 2 can both meet the requirement that the rice husk 6 will not leak. Compared with the circular holes 5 in the comparative example, the through-hole area is increased in the length direction, thereby improving the ventilation effect; the opening area of ​​the regular diamond holes 3 and the waisted diamond holes 4 on the upper surface of the metal sieve plate 1 is smaller than the opening area of ​​the lower surface. When the air on the upper surface rises after being heated by the wine lees, a small air pressure difference is formed on the upper and lower surfaces of the regular diamond holes 3 and the waisted diamond holes 4, which increases the flow rate of the cold air from the lower surface to the upper surface, further accelerating the cooling of the wine lees.

[0021] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
