Our Complete Garlic Bulb Cleaning & Grading Process (Step by Step)

Professional garlic processing is the key to consistent quality, clean appearance, and higher market value. Today we’re sharing our standardized step-by-step workflow for cleaning, sorting, and preparing premium garlic bulbs for sale.

Here is how we professionally process garlic bulbs from harvest to finished packaging:

🧄 Step 1: Root and Leaf Trimming

We start by cleaning up raw garlic using the HGRC-600 Garlic Root & Leaf Cutter. This machine precisely trims excess stems and dry roots, removing impurities and laying a clean foundation for subsequent brushing and grading.

🧄 Step 2: Surface Brushing and De-dusting

After trimming, garlic bulbs move to the brushing cleaning table. Professional soft brush rollers thoroughly remove surface soil, dust, and loose outer skins without damaging the garlic bulb surface, ensuring a clean and neat appearance.

🧄 Step 3: Uniform Feeding

Cleaned garlic bulbs are evenly fed into the machine hopper for automatic continuous sorting, avoiding manual stacking and uneven processing.

🧄 Step 4: Precision Size Grading

Using our custom roller screen garlic grading machine, bulbs are automatically classified into four standard sizes: small, medium, large, and extra-large. Unlike unstable manual sorting, the roller screen system ensures accurate, consistent, and repeatable grading for every batch.

🧄 Step 5: Standard Storage

After grading, qualified garlic bulbs are neatly placed in ventilated wire baskets and stored on dedicated shelves to maintain dryness, prevent secondary pollution, and preserve freshness.

🧄 Step 6: Final Packaging and Shipment

After final inspection, the cleaned and graded garlic is professionally packaged and delivered to customers worldwide.

Our custom roller screen grading machine is specially developed for large-scale garlic processing. It delivers precise, uniform size classification while greatly reducing manual labor. The stable mechanical grading standard eliminates human error, ensures every batch of garlic meets unified commercial standards, and greatly improves overall processing efficiency.

With reliable performance verified by field tests, our garlic grading equipment helps garlic farms streamline post-harvest workflows, stabilize product quality, and maximize economic benefits during every harvest season.
