[0022] The above structure is adopted, in order to reduce the system structure, a fixed frame 31 with an upper storage space and a lower storage space, a buffer hopper 32 and a lifting unit are provided, the second vibrating grading screen 11, the buffer hopper 32, and the second peeling machine 22 are placed in the upper storage space, and the de-stoner 13, the first peeling machine 21, and the third peeling machine 23 are placed in the lower storage space; the lifting unit includes a first elevator 41 for conveying the corn to be processed to the second vibrating grading screen 11, a second elevator 42 for conveying the corn to be processed output by the de-stoner 13 to the buffer hopper 32, a third elevator 43 for conveying the corn to be processed output by the first peeling machine 21 to the second peeling machine 22, and a fourth elevator 44 for conveying the corn to be processed output by the third peeling machine 23 to the first vibrating grading screen 24.

[0023] The powder brushing machine 53 and the single bin flat screen 56 are also placed in the upper storage space, and the germ extractor 51, the granulator 52, the packaging machine 57, the polisher 54 and the grinding machine 55 are placed in the lower storage space. For this reason, the machines having a communication relationship can be connected by pipelines, and there is no need to set up a conveying device.

[0024] The granulation and powder making unit further includes a first suction separator 561 and a second suction separator 562 connected to the single bin flat screen 56 for separating dust and black spots of different particle sizes.

[0025] In order to facilitate the transportation of particles and powders between the various devices, at least one of the following air mesh units is included: a conveying air mesh unit, a germ extractor air mesh unit 8, a stone remover air mesh unit 7, and a separator air mesh unit 9.

[0026] Specifically, the feeding air network unit includes a plurality of dischargers 61 and a first fan 62 connected to the discharger 61 ; the powder brushing machine 53 , the first peeling machine 21 , the second peeling machine 22 , and the third peeling machine 23 are all connected to the discharger 61 .

[0027] The germ extractor air network unit 8 is connected to the germ extractor 51 .

[0028] The stone removing machine air network unit 7 is communicated with the impurity screening unit.

[0029] The separator air network unit 9 is communicated with the first suction separator 561 and the second suction separator 562.

[0030] Exemplarily, such as Figure 1 As shown, in a system, 4 powder brushing machines 53 and 10 discharge devices are provided, and multiple packaging machines 57 are provided according to different materials to be packaged, so as to realize the packaging of powders and granular materials with different particle sizes. Adopting the system as Figure 1 shown, its operating principle is as follows:

[0031] The corn to be processed is stacked in the lower grain pit, and the raw materials are transported to the magnetic separation cylinder 12 by the first elevator 41 and then fall to the second vibrating grading screen 11 to screen out the metal and larger stones therein. After the screening is completed, the raw materials fall to the stone removing machine 13 through the conveying pipeline to further screen out the smaller stones.

[0032] The materials after screening out metal and stones are lifted by the second elevator 42 to the buffer hopper 32 for buffering. When granulation and powder making are required, the corn raw materials in the buffer hopper 32 fall to the first peeling machine 21 through the conveying pipeline for the first peeling, and the peeling rate can be set at 50%. The peeling machine 21 can adopt existing mature peeling machines. Then the raw materials are lifted to the second peeling machine 22 by the third elevator 43 for secondary peeling, and the peeling rate can be set at 80%. The raw materials after peeling by the second peeling machine 22 fall to the third peeling machine 23 through the conveying pipeline for tertiary peeling, and the peeling rate can be set at 95% or above. The fourth elevator 44 transports the corn to be processed output by the third peeling machine 23 to the first vibrating grading screen 24 for screening. The first vibrating grading screen 24 screens out the corn that has not been completely peeled and transports it to the second peeling machine 22 through the conveying pipeline. The peeled corn or particles with a particle size less than 8 meshes can be transported to the corresponding packaging machine 57 through pipeline B for packaging. The peeled corn can also be transported to the embryo extraction machine 51 through pipeline C for separating germ and radicle, and then enter the granulator 52 to make particles with a particle size meeting the requirements of customers.

[0033] The granulated corn is pneumatically conveyed into the corresponding discharger 61 and then flows into the flour brushing machine 53 to separate the flour in the produced small particles. The separated powder flows into the corresponding packaging machine 57 through the corresponding discharger 61 for packaging. The separated small particles flow into the polishing machine 54, and the dust and adhesions on the corn particles are separated through the brush structure, which also plays a polishing role. For example, the particles larger than 20 mesh flow into the flour mill 55 through the corresponding discharger 61 for flour production, and the particles of 8 - 20 mesh flow into the single - deck plan sifter 30 through the corresponding discharger 61 for particle classification. For example, the classification can be divided into less than 8 mesh, 8 - 12 mesh, and 12 - 20 mesh. The particles of 8 - 12 mesh are cleaned of dust, germ, and black spots through the first air - suction separator 561 and flow into the receiving table; the particles of 12 - 20 mesh are cleaned of dust, germ, and black spots through the second air - suction separator 562 and flow into the receiving table; Figure 1 One of the paths is that the particles less than 8 mesh as a spare flow into the third air - suction separator 563 through the corresponding discharger 61, and the impurities and black spots are cleaned again, and finally enter the granulator 52.

[0034] The flour mill 55 makes the small corn kernels into flour, which enters the flour brushing machine through the corresponding discharger 61 for separation. The separated flour flows into the corresponding packaging machine 57 through the corresponding discharger 61 for packaging, and the unqualified products in the flour brushing machine enter the flour mill 55 again for continuous flour production.

[0035] The corn husks removed by the first hulling machine 21 flow into the corresponding packaging machine 57 through the corresponding discharger 61 for feed powder packaging. The second hulling machine 22 and the third hulling machine 23 enter the corresponding flour brushing machine 53 through the corresponding discharger 61 for fat powder separation. The separated fat powder flows into the corresponding packaging machine 57 through the corresponding discharger 61 for fat powder packaging. The remaining raw materials in the flour brushing machine 53 enter the feed crusher 10 for crushing, flow into the flour brushing machine 53 through the corresponding discharger 61, and the separated fat powder flows into the corresponding packaging machine 57 through the corresponding discharger for packaging. The remaining materials in the flour brushing machine 53 flow into the corresponding packaging machine 57 for feed packaging.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
