A Comprehensive Guide to Chickpea Processing: Step-by-Step Stages

Introduction Chickpeas, revered for their versatility and nutritional benefits, undergo a meticulous processing journey before reaching consumers in various forms. Chickpea processing plants employ a series of essential steps, including pre-cleaning, fine cleaning and calibrating, destoning, gravity table, optical sorting, final control inspection by sieve separator, and bagging. In this blog, we will delve into each stage to uncover the secrets behind the efficient transformation of raw chickpeas into high-quality, market-ready products. Step 1: Pre-Cleaning

Raw Chickpea Intake: Raw chickpeas are received in bulk at the processing plant, sourced from farms or suppliers. The initial quality inspection ensures only the best chickpeas move forward.

Pre-Cleaning: Meticulous pre-cleaning techniques, including sieves, air aspirators, and gravity separators, effectively remove larger impurities such as stones, twigs, leaves, and other foreign materials.

Optional Magnetic Separation: Magnetic separators may be employed to eliminate any metal contaminants present in the chickpeas.

Step 2: Fine Cleaning and Calibrating

Fine Cleaning: The pre-cleaned chickpeas undergo further cleaning to remove smaller impurities and ensure a cleaner product.

Calibrating: Chickpeas are calibrated to achieve uniform size, facilitating consistent processing and enhancing the quality of the final product.

Step 3: Destoner

Destoning: Specialized equipment, known as destoners, efficiently remove stones and heavier impurities from the chickpeas. This step ensures the purity and integrity of the product.

Step 4: Gravity Table

Gravity Table: The gravity table uses gravity and airflow to separate chickpeas based on density, effectively removing undersized or damaged chickpeas.

Step 5: Optical Sorting

Optical Sorter: Employing advanced optical technology, optical sorters detect and eliminate defective or discolored chickpeas from the product stream. High-speed cameras and sensors ensure precision and accuracy in the sorting process.

Step 6: Final Control Inspection by Sieve Separator

Final Control Inspection: Chickpeas undergo a final inspection using a sieve separator. This step guarantees that only the finest and highest-quality chickpeas proceed to the next stage.

Step 7: Bagging

Bagging: The processed and sorted chickpeas are carefully and hygienically bagged, ready for distribution to wholesalers, retailers, or consumers. Proper packaging ensures the product remains fresh and retains its quality.

Conclusion Chickpea processing plants meticulously follow a well-structured series of steps, including pre-cleaning, fine cleaning and calibrating, destoning, gravity table, optical sorting, final control inspection by sieve separator, and bagging. By adhering to these precise stages, these processing plants successfully deliver high-quality, uniform chickpeas to meet the diverse demands of consumers worldwide. With continuous technological advancements, chickpea processing is poised to remain efficient, delivering delicious and nutritious chickpea products to enrich global cuisines and diets.
