DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects of the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0018] It should be noted that when an element is referred to as being "disposed on", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or indirectly on, connected or coupled to the other element. It should be understood that the terms "on", "under", "front", "back", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. The terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of the present application, the meaning of "a plurality of" or "several" is two or more, unless otherwise explicitly specified.

[0019] Please refer to Figure 1 , the present application will be described. The system, including the crusher 10, the first grinding machine 20, screening device 30 and the second grinding machine 40 are connected in sequence; wherein, the crusher 10 is used to break the complete block into large particle block; the first grinding machine 20 is used to grind the large particle block into a mixture of powder and small particle block, screening device 30 is used to separate the powder and small particle block, the second grinding machine 40 is used to grind the small particle block into powder; wherein, the powder outlet of screening device 30 and the second grinding machine 40 are connected to the powder buffer bin through the powder conveying pipeline 50.

[0020] It should be noted that the above crusher 10 in the embodiment can be a combination of existing block grinder, screening device 30 can be a single bin or multi bin vibrating screen, the first grinding machine 20 and the second grinding machine 40 can adopt the traditional grinding machine, the powder conveying pipeline 50 is the pipeline matched with the winery for negative pressure conveying powder, the above devices or equipment are all existing in structure, which will not be described in detail here.

[0021] Since the complete koji block is usually a cubic structure of about three kilograms, the volume is large, so it first passes through the crusher 10 for preliminary crushing before entering the first flour mill 20, so that the complete koji block forms large particle koji blocks of different sizes into the first flour mill 20. After grinding in the first flour mill 20, the relatively smaller particles in the large particle koji block directly form koji powder of the target particle size, while the relatively larger particles in the large particle koji block cannot directly form koji powder after passing through the first flour mill 20, but are crushed into small particle koji blocks. Therefore, the first flour mill 20 discharges a mixture of koji powder and small particle koji blocks. After passing through the screening device 30, the koji powder as undersize can directly enter the koji powder conveying pipeline 50 and be sent to the koji powder buffer bin, while the small particle koji blocks as oversize are again introduced into the second flour mill 40. After being ground into koji powder by the second flour mill 40, it is sent to the koji powder buffer bin by the koji powder conveying pipeline 50. After the above-mentioned three crushing processes, the koji powder can avoid the inclusion of koji block particles, and the uniformity of the particle size of the koji powder is ensured.

[0022] The koji block crushing system provided in the embodiment can avoid the inclusion of koji block particles in the final koji powder, and ensure the uniformity of the particle size of the koji powder, which is beneficial to improve the quality of the wine and meet the needs of high-end wine brewing process.

[0023] In some embodiments, referring to Figure 1 , the koji block crushing system further comprises a bucket elevator 60; wherein the first flour mill 20, the screening device 30, and the second flour mill 40 are sequentially distributed from top to bottom, the crusher 10 is located on the side of the screening device 30, and the bucket elevator 60 is located between the crusher 10 and the screening device 30, used to receive and transfer the large particle koji blocks from the crusher 10 to the first flour mill 20.

[0024] After the crusher 10 preliminarily crushes the complete koji block, the large particle koji blocks can fall into the hopper of the bucket elevator 60. Then, after the hopper is lifted to the upper side of the first flour mill 20, the large particle koji blocks can be directly discharged from the hopper into the first flour mill 20. The mixture of koji powder and small particle koji blocks discharged from the first flour mill 20 can directly fall into the screening device 30, and the small particle koji blocks screened out can directly fall into the second flour mill 40. The overall layout is compact and facilitates the sequential transfer of materials, which is beneficial to reduce the cost of material conveying.

[0025] It should be noted that, as shown in Figure 1 , a spiral conveyor 70 is arranged between the first flour mill 20 and the top end of the bucket elevator 60, and the spiral conveyor 70 is used to receive the large-particle dough blocks from the top end of the bucket elevator 60 and convey the large-particle dough blocks to the first flour mill 20. Since the hopper of the bucket elevator 60 directly pours the large-particle dough blocks into the first flour mill 20, it is easy to cause the first flour mill 20 to be blocked and overloaded, and it also affects the flour yield of the first flour mill 20. Therefore, the spiral conveyor 70 is used to receive the large-particle dough blocks from the bucket elevator 60, so that the large-particle dough blocks are uniformly dropped into the first flour mill 20 under the conveying of the spiral conveyor 70, thereby improving the flour yield of the first flour mill 20.

[0026] In order to avoid the large-particle dough blocks from being mixed with iron particles and entering the first flour mill 20 to cause damage to the equipment, please refer to Figure 1 , a magnetic separator 80 is arranged between the spiral conveyor 70 and the first flour mill 20, and the large-particle dough blocks enter the first flour mill 20 through the magnetic separator 80.

[0027] As a specific embodiment of the above-mentioned crusher 10, please refer to Figure 1 , the crusher 10 has at least two layers of crushing chambers 11 stacked in an upper and lower manner, and the crushing particle size of each layer of crushing chamber 11 decreases layer by layer from top to bottom. That is to say, the above-mentioned crusher 10 is a combined dough crusher 10 with a multi-layer crushing structure, and the top layer is configured with corresponding crushing rollers such as wolf tooth rollers for the volume of the complete dough, and the middle and lower layers can use tooth surface crushing rollers and the roller spacing gradually decreases from top to bottom. In this way, it can avoid the situation that the dough volume is too large to be smoothly fed into the crushing roller, improve the crushing efficiency, and at the same time, it is also beneficial to the layer-by-layer crushing to improve the uniformity of the large-particle dough, thereby promoting the improvement of the uniformity of the dough particle size.

[0028] In some possible implementations, please refer to Figure 1 , the dough crushing system further includes a feeding assembly 90, which is located above the crusher 10 and is used to receive and convey the dough pile and make the dough pile fall into the crusher 10 by gravity. When feeding, the workshop overhead crane or forklift can be directly used to pour the dough pile into the feeding assembly 90, and then the complete dough is dropped into the crusher 10 by using the feeding assembly 90. The feeding is convenient and efficient.

[0029] In some embodiments, the above-mentioned feeding assembly 90 adopts, for example Figure 1The structure shown, which comprises a chain channel conveyor 91, a turnover machine 92 and a feeding chute 93; wherein the feeding chute 93 is vertically connected to the feeding port of the crusher 10, and the upper end of the feeding chute 93 is provided with a receiving port 931; the chain channel conveyor 91 is used to receive and transmit the curved block material pile to the receiving port 931; the turnover machine 92 is arranged between the chain channel conveyor 91 and the receiving port 931, and is used to overturn the curved block material pile from the chain channel conveyor 91 to the receiving port 931.

[0030] The chain channel conveyor 91 is used to conveniently transmit the curved block material pile as a whole, and when the curved block material pile approaches the feeding port of the feeding chute 93, the turnover machine 92 tilts the curved block material pile into the feeding port, so that the complete curved blocks stacked and placed are scattered and fall into the feeding chute 93, and are guided by the feeding chute 93 to enter the crusher 10; based on the above action, the curved block material pile is only needed to be placed on the chain channel conveyor 91 to realize automatic feeding of the crusher 10, thereby saving manpower and improving efficiency.

[0031] Specifically, as shown in the drawings, Figure 1 The feeding chute 93 in the embodiment is connected with a powder suction pipe 932, and the powder suction pipe 932 is connected with the curved powder conveying pipeline 50. Since the complete curved blocks collide with each other during the tilting and pouring into the feeding chute 93, the curved blocks are broken, and thus floating curved powder is generated; the curved powder in the feeding chute 93 is suctioned to the curved powder conveying pipeline 50 by the powder suction pipe 932, so that the curved powder can be avoided from being wasted, and the curved powder can be avoided from being blown out of the feeding port to affect the air quality of the environment.

[0032] It should be understood that, please refer to Figure 1 In the embodiment, a powder collecting box 51 connected with the curved powder conveying pipeline 50 is arranged below the second flour mill 40, the powder outlet of the screening device 30 and the second flour mill 40 are respectively connected to the powder collecting box 51 through a falling pipe 41, and the powder suction pipe 932 is connected to the powder collecting box 51. The curved powder collected from various places is uniformly sent to the curved powder conveying pipeline 50 to the curved powder buffer warehouse by the powder collecting box 51, so that the utilization rate of the curved powder conveying pipeline 50 is improved, and the pipeline facility cost is saved.

[0033] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
