In the field of pulse and grain processing, “purity” and “uniformity” are core quality criteria. Whether it’s edible beans like red beans and mung beans, or beans for processing like soybeans and peas, impurities such as stones, mud, insect-damaged beans, and shrunken beans are inevitably mixed in during harvest. These impurities may resemble the beans themselves or be hidden between the grains. Manual sorting alone is not only inefficient but also difficult to completely remove, becoming a key challenge affecting bean quality and hindering production efficiency. The emergence of pulse and grain gravity machines, with their innovative “sorting by weight” logic, provides an efficient and precise solution for controlling bean quality.
Unlike traditional color sorters, which focus on color differences, pulse and grain gravity separator address the core pain point of bean sorting—precise separation by leveraging the differences in specific gravity of different substances. It’s equipped with a high-precision gravity sorting system that simulates natural gravity sorting principles, combining adjustable-speed vibrating conveying with wind-force regulation technology to separate beans and impurities into “strata” on a specific sorting bed. Heavy impurities like stones and metal shavings sink to the bottom layer due to gravity and are quickly separated and discharged. Lighter, shrunken beans, insect-damaged beans, and empty shells float upward with the airflow and are precisely screened out. High-quality beans with full grains and uniform gravity remain stable in the middle layer, following a pre-set path to the qualified product channel. The entire process eliminates manual judgment and is unaffected by bean color or size. Even glass fragments, lumps of soil, and partially shrunken beans that are difficult to distinguish with the naked eye can be completely separated based on their gravity differences, achieving a sorting purity of over 99.5%.
For bean processing companies and growers, the value of the bean and grain gravity machine goes far beyond impurity removal. In large-scale production, it can efficiently process several tons of beans per hour, far exceeding manual sorting efficiency and significantly reducing labor costs. It also prevents bean breakage during manual sorting, preserving the integrity of the beans. Regarding quality control, it ensures that each batch of beans is uniform and free of impurities. Whether used in food processing, canning, bean products, or selling as seeds, it meets high quality standards and enhances product bargaining power in the market. Regarding safety, it precisely removes hard impurities such as stones and metal, preventing wear and tear on subsequent processing equipment and eliminating safety hazards for consumers, thereby strengthening the company’s reputation for quality.
Our Taobo bean and grain gravity machine can flexibly adjust sorting parameters based on the characteristics of different bean varieties, such as red beans, mung beans, soybeans, and kidney beans, to meet diverse needs. It is not only a sorting device, but also a “quality gatekeeper” in the bean industry chain – allowing each bean to stand out with its own high-quality proportion, making the processing link more efficient and the terminal products more secure, helping practitioners to win the trust of consumers with “pure quality” in the competition in the bean market, and injecting solid impetus into the high-quality development of the bean industry.
