Description

Technical Field

[0001] This utility model relates to the field of grain proportioning technology, specifically to a quantitative proportioning device for grain processing. Background Technology

[0002] Quantitative proportioning in grain processing involves using scientific methods to mix grains of different characteristics or varieties in precise proportions to improve product quality, stabilize production, and meet diverse needs. Its core lies in accurate measurement and uniform mixing. Therefore, how to improve the consistency between measurement and uniform mixing is an urgent problem to be solved.

[0003] A search revealed that CN218987619U discloses a quantitative proportioning device, comprising a proportioning box system, a pusher plate system, and a scraper system. The pusher plate system is movably inserted into one end of the proportioning box system, allowing for adjustment of the box's volume by moving back and forth. A pusher column, with a pusher plate connected to one end, is movably inserted into one end of the box, and the pusher plate is movably connected inside the box. The scraper system is movably inserted into the proportioning box system. When quantitatively dispensing powdered fermentation materials, the volume of the box is changed by adjusting the position of the pusher plate within it. The powdered fermentation materials are then poured into the box, and finally, the excess powdered fermentation materials at the box opening are scraped off by moving the scraper system. This achieves quantitative dispensing of powdered fermentation materials, which is more convenient and faster than the traditional weighing method.

[0004] The problem with the above-mentioned quantitative proportioning device is that:

[0005] The proportioning and mixing process is disconnected: After the quantitative material is taken out by adjusting the volume with a push plate and leveling with a scraper, the material needs to be manually transferred to an independent mixing device. The process is interrupted, resulting in low efficiency, and the transfer process is prone to proportioning errors or material residues.

[0006] It is only suitable for powdery materials and has poor adaptability to granular grains: the pusher-type volume adjustment and scraper leveling operation are prone to squeezing or breaking granular grains (such as cereals and beans), and the metering accuracy is low for granules with poor flowability.
