[0036] Reference Figure 1-3 As shown, an embodiment of the present application provides a fermentation product screening device, including a vibrating screen 1, a conveyor belt 2 and a particle turning device.

[0037] Reference Figure 1-2 As shown, the vibrating screen 1 screens the coarse material of the product and separates the target particles that meet the particle size requirements from the particles that do not meet the requirements. The appropriate model and type can be selected according to actual needs. In this embodiment, a circular vibrating screen 1 is used as an example.

[0038] Reference Figure 1-2As shown, conveyor belt 2 is used to receive the target particle product output from vibrating screen 1 and transport it to the packaging station. Specifically, the input end of conveyor belt 2 is close to vibrating screen 1, and the conveying surface height is lower than the target particle output height of vibrating screen 1 to ensure that the product output from vibrating screen 1 lands on conveyor belt 2. Conveyor belt 2 must meet production hygiene requirements. In this embodiment, the conveying surface of conveyor belt 2 is shown as horizontal.

[0039] The particle turning device is arranged above the conveyor belt 2 and is used to turn over the material conveyed on the conveyor belt 2 so that the lower layer of material is turned to the upper layer. It includes a first turning component and a second turning component arranged at intervals in the conveying direction of the conveyor belt 2.

[0040] Reference Figure 1-2 As shown, specifically, the first turning assembly includes multiple first turners 3, the first turners 3 are frustum-shaped and the axis is perpendicular to the conveying surface of the conveyor belt 2, the end face of the first turner 3 with a larger diameter is in contact with the conveying surface of the conveyor belt 2, and the multiple first turners 3 are arranged at intervals along the width direction of the conveyor belt 2.

[0041] With the above arrangement, when the material is transported on the conveyor belt 2, before reaching the first turner 3, defective particles in the surface material are manually sorted. When the material reaches the first turner 3 and passes through the first turner 3, due to the frustum-shaped structure of the first turner 3, its side walls act as a drainage and guide for the material, causing the material to flow to both sides and turn over, thereby turning the lower layer of material to the upper layer. Subsequently, defective particles are manually sorted out to remove as many defective particles as possible from the material.

[0042] Reference Figure 1-2 As shown, the second turning assembly includes a plurality of second turners 4, the second turners 4 are in a truncated cone shape and the axis is perpendicular to the conveying surface of the conveyor belt 2, the end face of the second turner 4 with a smaller diameter is in contact with the conveying surface of the conveyor belt 2, and the plurality of second turners 4 are spaced apart along the width direction of the conveyor belt 2. The second turner 4 is truncated cone-shaped, and the side walls also play a role in draining and guiding the material passing through it, so that the material flows to both sides and turns the material, turning the bottom layer of material to the upper layer. The first turning assembly and the second turning assembly are spaced apart in the conveying direction of the conveyor belt 2, and cooperate with each other to improve the turning effect of the material, so that the bottom layer of material is fully turned to the upper layer, and the defective particles are fully removed when the defective particles are subsequently sorted.

[0043] Furthermore, the first turning assembly and the second turning assembly are arranged in sequence in the conveying direction of the conveyor belt 2, so that the material passes through the first turning assembly first and then the second turning assembly, which has a better turning effect on the material. Since the material is reversed to both sides after passing through the first turning device 3, in order to make the second turning device 4 play a better role, the projections of multiple first turning devices 3 and multiple second turning devices 4 on the vertical plane perpendicular to the conveying direction of the conveyor belt 2 are staggered. In this way, the two material flows diverted by the first turning device 3 each pass through a second turning device 4 and are turned by the second turning device 4.

[0044] Reference Figure 1-2 As shown, a flattening roller 5 is disposed above the conveyor belt 2. The flattening roller 5 and the particle turning device are arranged sequentially along the conveying direction of the conveyor belt 2. The axis of the flattening roller 5 is parallel to the width direction of the conveyor belt 2. The flattening roller 5 is disposed above the conveying surface of the conveyor belt 2 and is spaced apart from the conveying surface. The flattening roller 5 spreads the material that has been diverted and accumulated on both sides by the first and second turners 3 and 4 along the width direction of the conveyor belt 2, facilitating subsequent manual sorting of defective particles and preventing incomplete sorting of defective particles due to thick material accumulation.

[0045] Reference Figure 1-3 As shown, in order to evenly distribute the material output from the vibrating screen 1 on the conveyor belt 2, a uniform distribution hopper 6 is provided between the conveyor belt 2 and the vibrating screen 1. The uniform distribution hopper 6 includes a feed port and a discharge port distributed vertically up and down. The feed port of the uniform distribution hopper 6 is connected to the target particle output port of the vibrating screen 1, and the discharge port extends above the input end of the conveyor belt 2. The width of the uniform distribution hopper 6 in the width direction of the conveyor belt 2 gradually increases from the feed port to the discharge port. A plurality of partitions 61 are provided in the uniform distribution hopper 6. The plurality of partitions 61 are spaced apart along the width direction of the conveyor belt 2. The plurality of partitions 61 divide the uniform distribution hopper 6 into a plurality of material channels distributed sequentially in the width direction of the conveyor belt 2. The plurality of material channels are not connected to each other, and the two ends of each material channel are respectively connected to the feed port and the discharge port of the uniform distribution hopper 6. Specifically, the feed port of the uniform distribution hopper 6 is provided with a feed hopper, and the feed hopper is connected to the target particle output port of the vibrating screen 1. The vibrating screen 1 outputs the material from the feed hopper into the uniform distribution hopper 6. The material enters multiple material channels from the feed port of the uniform distribution hopper 6 and is output from the discharge port along the material channel. Since the discharge ports are distributed in sequence in the width direction of the conveyor belt 2, the material falls evenly on the conveyor belt 2 in the width direction of the conveyor belt 2, which is convenient for picking out defective particles in the material transported on the conveyor belt 2.

[0046] Reference Figure 1-2As shown, a lighting fixture 7 is provided above the conveying surface of the conveyor belt 2 to illuminate the conveying surface. The lighting fixture 7 enhances the brightness of the conveying surface of the conveyor belt 2, making it easier for personnel to detect defective particles. In this embodiment, the lighting fixture 7 is a light strip arranged along the conveying direction of the conveyor belt 2. During actual installation, brackets for mounting the particle turning device, flattening roller 5, uniform distribution hopper 6, and lighting fixture 7 can be provided on the mounting frame of the conveyor belt 2 as needed.

[0047] Reference Figure 1 As shown, the embodiment of the present application also provides a fermentation product screening system, which includes a mixing barrel (not shown in the figure), the fermentation product screening device as above, a vacuum loader (not shown in the figure) and a receiving hopper 8. The product coarse material is in the mixing barrel, the input end of the vacuum loader is connected to the mixing barrel, and the output end is connected to the input end of the vibrating screen to lift the material in the mixing barrel and transport it to the vibrating screen 1. The receiving hopper 8 is provided at the output end of the conveyor belt 2, and is used to receive the material output by the conveyor belt 2. The discharge port of the receiving hopper 8 is provided with an iron remover 9. Specifically, the iron remover 9 adopts a drawer-type iron remover 9. The qualified product particles output by the conveyor belt 2 after screening and sorting are input into the receiving hopper 8, and are input into the packaging bag after passing through the iron remover 9 to complete the product screening work.
