High-quality quinoa cleaning machine is more than just a simple “sieve,” but rather a “multifunction integrated system” designed based on quinoa’s physical properties (specific gravity, particle size, color, elasticity, etc.). Its core functions can be summarized in three key dimensions:
1. Precision impurity removal: Separately remove various impurities
Quinoa cleaning machine utilizes a multi-process synergy to achieve stratified impurity removal:
Primary cleaning (removing large and light impurities): Using a combination of a vibrating screen and air separation, the vibrating screen’s large-aperture mesh first separates larger impurities such as straw, weeds, and gravel. The airflow generated by the fan then removes lighter impurities such as dust and shrunken straw, completing “rough cleaning.” Selection (Removing Small Impurities and Low-Quality Kernels): Quinoa entering the second stage passes through a “gravity separator.” This machine utilizes the difference in specific gravity between quinoa and small impurities (such as fine sand and broken shells). Airflow over an inclined screen separates quinoa grains (specific gravity approximately 1.2g/cm³) from impurities (specific gravity approximately 0.8-1.0g/cm³), with the impurities discharged from the lower layer. Simultaneously, a “color sorter” identifies moldy and insect-infested kernels (with abnormal color) and uses high-pressure airflow to precisely remove them, achieving “fine purification.”
This process reduces the impurity content of quinoa from an initial 5%-10% to below 0.3%, fully meeting international standards. 2. Grading and Screening: Categorizing Quality Grades Based on Demand
Different markets have varying requirements for quinoa particle size and plumpness.
Quinoa sorting machine uses an adjustable grading screen equipped with meshes of varying apertures (typically 1.8-3.2mm) to sort the cleaned quinoa into 3-5 particle size grades, ensuring high quality and high prices.
3. Reducing Waste: Ensuring Yield and Economic Benefits
Traditional manual sorting is not only inefficient (each person can only process 50-100kg per day), but is also prone to manual screening errors, leading to the loss of high-quality quinoa along with impurities, resulting in a loss rate of up to 5%-8%. Modern quinoa sorting machine, however, can reduce the loss rate to less than 1%, and a single machine can process 5-50 tons per day (depending on the model). This improves efficiency, reduces waste, and directly increases economic benefits for businesses.
