Description

Technical Field

[0001] The utility model belongs to the technical field of bio-based material processing, and in particular relates to a bio-based material screening and processing device. Background Art

[0002] Bio-based materials are new materials and chemicals made from renewable biomass such as grains, legumes, straw, bamboo and wood powder, etc., including basic bio-based chemicals obtained through biosynthesis, bioprocessing, and biorefining processes.

[0003] When producing and processing bio-based materials using grains, legumes, etc. as raw materials, the raw materials are first screened to remove defective products. Existing screening devices of this type generally use sieve plates for screening, but the raw materials usually contain lighter impurities such as husks and dust, which are difficult to remove, resulting in low screening efficiency.

[0009] As a preferred embodiment, two discharge ports are provided on one side of the screening box, and baffles are hinged inside the discharge ports.

[0010] As a preferred embodiment, a door is hinged on one side of the dust collecting box.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The bio-based material screening and processing device is provided with a blower, a blowing plate, a dust hood, a dust suction pipe, a suction fan and a dust collection box. During screening, the blower and the suction fan can be started to make the blowing plate blow air in the direction of the dust collection box, so that the dust collection box can suck the husks and dust in the raw materials into the dust collection box, thereby improving the screening efficiency.
