[0001] The invention relates to the technical field of fermented black beans processing, in particular to a device for efficiently cleaning and sorting fermented black beans raw materials. Background Art

[0002] In the production of fermented black beans, the quality of raw material pretreatment directly affects the quality of the final product. Pretreatment must complete two core tasks: impurity separation and surface cleaning. The traditional processing method is to use a bamboo sieve to screen black beans of different sizes, and then select the black beans of uniform size suitable for making fermented black beans. This is inefficient.

[0003] Prior art CN111804570B discloses a black bean screening machine with a cleaning function before fermented black beans are produced. The machine comprises an L-shaped plate, a fixing base, a material storage frame, a material guide frame, a screening frame shaking mechanism, and a screening frame body. Two fixing bases, each with a plurality of circular holes, are symmetrically mounted on the L-shaped plate. The material storage frame is fixed to the two fixing bases, and the material guide frame is fixed to one side of the two fixing bases. This allows the black beans in the material storage frame to intermittently fall into the screening frame body, and the shaking of the screening frame body allows the black beans to be fully screened, thereby improving the screening efficiency of the black beans.

[0004] The above device can improve the screening efficiency of black beans, but the above device mainly relies on the water flow flushing of the spray pipe, and has limited effect on cleaning impurities stubbornly attached to the surface of the raw materials, affecting the subsequent processing of fermented black beans. Summary of the Invention

[0012] On the other hand, the present invention also includes a method for efficiently cleaning and sorting fermented black bean raw materials, which is applied to the device for efficiently cleaning and sorting fermented black bean raw materials, comprising the following steps:

[0013] The fermented black bean curd raw material is poured into the pre-cleaning component, and the raw material is screened by the pre-cleaning component to remove heavy impurities such as stones and soil blocks, and at the same time separate light impurities such as dust. The raw material after preliminary purification enters the cleaning tank;

[0014] The air source, the rotating motor and the water supply pipe are started. The air source supplies air to the aeration disk to generate bubbles to disturb the water flow.

The raw materials and water are separated by the drain seat, so that the raw materials slide into the screening component along the drain seat for sorting, and the water flows into the drain seat for recovery, thereby achieving the purpose of improving the cleaning effect of the fermented black bean raw materials.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] First embodiment:

[0030] The present invention provides an efficient cleaning and sorting device for fermented black bean raw materials, comprising a screening component 101 and a cleaning component 102, wherein the cleaning component 102 comprises a cleaning tank 103, an aeration plate 104, a rotating brush 105, a drain seat 106, a pre-cleaning component 107, a water supply pipe 110 and a slag screen 111, the drain seat 106 comprises a seat body 114 and a drain plate 115, the cleaning tank 103 is provided with an overflow tank 117, the screening component 101 comprises a base 121, a sieve plate 122 and a collecting basket 123, and the cleaning effect of the fermented black bean raw materials is improved by the aeration plate 104 and the rotating brush 105. It can be understood that the above scheme can be used to improve the cleaning effect of the fermented black bean raw materials, and can also be used to filter impurities in the water inside the cleaning tank 103.

[0031] According to this specific embodiment, the screening component 101 is used to screen the fermented black beans raw material after being cleaned by the cleaning component 102 .

[0032] The cleaning tank 103 is arranged on one side of the screening assembly 101, the aeration plate 104 is fixedly connected to the cleaning tank 103 and is located inside the cleaning tank 103, the rotating brush 105 is rotatably connected to the cleaning tank 103 and is located inside the cleaning tank 103, the drain seat 106 is fixedly connected to the cleaning tank 103 and is located between the cleaning tank 103 and the screening assembly 101, and the pre-cleaning component 107 is arranged on one side of the cleaning tank 103; the pre-cleaning component 107 can perform preliminary impurity separation on the fermented black bean raw material before it enters the cleaning tank 103. There are multiple aeration plates 104 and rotating brushes 105, which are alternately distributed inside the cleaning tank 103. A number of aeration holes are provided on the upper surface of the aeration plate 104, and the aeration plate 104 is connected to the air source (not shown in the figure) through a pipeline. A plurality of rotating motors 108 are provided on one side of the cleaning tank 103, and the output end of the rotating motor 108 is connected to the rotating brush 105. A discharge port 109 is also provided on the side of the cleaning tank 103 close to the drain seat 106, and the water and raw materials inside the cleaning tank 103 can be discharged to the drain seat 106 through the discharge port 109.

[0033] During use, the raw materials are poured into the feed port of the pre-cleaning component 107. The pre-cleaning component 107 first screens and removes impurities such as stones and soil in the raw materials to complete the initial impurity separation. Then, the pre-cleaned raw materials fall into the cleaning tank 103 from the end of the pre-cleaning component 107. At this time, the air source and the rotating motor 108 are turned on. The aeration disc 104 releases fine bubbles through the aeration holes. When the bubbles rise, they disturb the water flow, peeling off impurities such as mud and sand attached to the surface of the raw materials, and preventing the raw materials from sinking to the bottom. The rotating brush 105 is driven by the rotating motor 108. The rotating brush 105 rotates synchronously, and the rotation direction of the rotating brush 105 is consistent with the moving direction of the raw material. The bristles of the rotating brush scrub the surface of the raw material to remove stubborn stains. At the same time, with the help of water flow, the raw material is pushed to move toward the outlet along the cleaning trough 103. The water flow and the cleaned raw material fall onto the drain seat 106 through the discharge port 109. The raw material and water are separated by the drain seat 106, so that the raw material slides into the screening component 101 along the drain seat 106 for sorting, and the water flows into the drain seat 106 for recovery, thereby achieving the purpose of improving the cleaning effect of the fermented black bean raw material.

[0034] Secondly, the water supply pipe 110 is fixedly connected to the cleaning tank 103 and communicated with the cleaning tank 103; the water supply pipe 110 is communicated with the external water supply pipe, and the water supply pipe 110 is arranged on the side of the cleaning tank 103 away from the discharge outlet 109. Water is supplied to the water supply pipe 110 through the external water supply pipe, so that clean water from the outside is injected into the cleaning tank 103 through the water supply pipe 110, ensuring that the raw materials are always immersed in the cleaning process to avoid insufficient cleaning due to too low water level; at the same time, the water flow direction is toward the discharge outlet 109, further enhancing the propulsion force on the raw materials and avoiding the accumulation of raw materials inside the cleaning tank 103.

[0035] At the same time, the slag net 111 is slidably connected to the cleaning trough 103 and is located inside the cleaning trough 103; there are multiple slag nets 111, and a handle 112 is provided on the top to facilitate the disassembly of the slag net 111. The cleaning trough 103 is provided with an installation groove 113 that cooperates with the slag net 111. The slag net 111 can be inserted into the installation groove 113 for installation. After the slag net 111 is installed in place, there is a gap between its bottom and the bottom of the cleaning trough 103, which allows the fermented black bean raw material to pass through, and impurities floating on the water surface, such as bean skin, foam, impurity flocs, etc. are intercepted by the mesh surface of the slag net 111. The impurities will accumulate on one side of the mesh surface under the push of the water flow, which is convenient for centralized cleaning.

[0036] In addition, the base 114 is fixedly connected to the cleaning tank 103 and is located on one side of the cleaning tank 103; the drain plate 115 is fixedly connected to the base 114 and is arranged on the base 114; the drain plate 115 is arranged at an angle, and its side close to the screening component 101 is lower in height, and the drain plate 115 is provided with sieve holes, which can allow water to pass through but not the fermented black bean raw materials; when the cleaned raw materials and water flow onto the drain plate 115, the water flows into the base 114 through the sieve holes, and a drain pipe is provided at the bottom of the base 114, so that the water can be discharged through the drain pipe, while the raw materials slide along the plate surface due to their own weight and the inclination of the drain plate 115 until they slide to the screening component 101 for screening; a filter plate 116 is also installed inside the base 114, and the impurities in the water are filtered through the filter plate 116, so that the filtered water can be recycled or used for other purposes, saving resources.
