As a high-protein and high-nutrition legume, pigeon peas have long faced “three major difficulties” in the cleaning process: first, the shape of pigeon pea particles is irregular, and the physical properties are little different from sand, gravel, soil lumps, and broken beans. Traditional grain cleaning machines are difficult to accurately separate impurities, and manual sorting is inefficient and costly; second, the seed coat of pigeon peas is relatively thin, and the high friction operation of traditional equipment can easily cause the seed coat to be damaged, affecting the product appearance and storage stability; third, farmers mainly plant in a scattered manner and process on a small scale, and lack suitable miniaturized, low-cost cleaning equipment, which restricts the quality improvement of pigeon peas and their market premium ability.
The three core advantages of our cleaning equipment:
1、Three-dimensional precise sorting, with an impurity removal rate exceeding 99%
The innovative triple sorting technology of “specific gravity separation + color sorting and identification + particle size screening” is adopted. Sand, gravel and soil blocks are separated by specific gravity differences, and then the color sorting system is used to identify moldy and discolored beans. Finally, the customized screen is used to screen the broken particles to achieve “layer-by-layer peeling” of impurities, ensuring that the purity of pigeon beans after cleaning reaches food grade and seed grade standards.
2、Flexible conveying protects the seed coat, and the breakage rate is controlled within 0.3%:
the equipment conveying channel adopts food-grade soft materials. During the sorting process, the low-speed roller and slow airflow design are used to reduce the friction and collision between the pigeon peas and the equipment. According to actual measurements, the seed coat breakage rate after cleaning is only 0.3%, which is much lower than the average level of 3% of traditional equipment, preserving the product appearance to the greatest extent.
3、Intelligent speed control saves energy, reduces costs, increases efficiency, and is more environmentally friendly:
Equipped with an intelligent system, it can automatically adjust the speed and airflow intensity according to the moisture content and impurity content of the pigeon peas, saving 20% energy compared to traditional equipment. At the same time, the closed design reduces dust overflow during the cleaning process, meets environmental protection requirements, and takes into account both operational efficiency and green production.
The introduction of the sorting machine not only resolves the bottleneck in specialty bean processing but also promotes equipment upgrades in the grain and bean industry. With the widespread adoption of this equipment, the quality and competitiveness of pigeon peas are expected to be further enhanced.
