The commercial garlic grading machine is an essential piece of equipment for garlic farms, processing plants, and agricultural cooperatives looking to streamline their sorting operations. This advanced sorting system uses a precision roller-bar conveyor mechanism to classify garlic bulbs by size with remarkable accuracy, processing between 800 to 4,000 kg per hour depending on the model.
Unlike traditional manual sorting methods that are labor-intensive, time-consuming, and prone to human error, our automated garlic grading machine delivers consistent, accurate results while protecting the integrity of each bulb. The innovative roller-bar design ensures gentle handling throughout the sorting process, preventing bruising or damage that could reduce shelf life and market value.
With over 20 years of manufacturing experience, Shuliy Machinery has exported these grading machines to Pakistan, Saudi Arabia, India, Thailand, Italy, and numerous other countries. Our equipment helps agricultural businesses increase efficiency, reduce labor costs, and command better prices through proper size grading.

Key features and functional advantages
Integrated elevator and grading system
Our garlic grading machine features a seamlessly integrated lifting and grading system. The elevator automatically feeds garlic from ground level to the grading mechanism, eliminating the need for manual lifting and reducing labor requirements. This continuous feeding system ensures uninterrupted operation and maximizes throughput.
Roller-bar conveyor technology
The proprietary roller-bar conveyor system represents a significant advancement over traditional belt conveyors. Each roller rotates independently, allowing garlic bulbs to self-align and move smoothly through the grading process. The silicone-coated rollers provide gentle yet firm grip, preventing slippage while protecting the garlic skin from abrasion.
Adjustable grading levels
Choose from 3, 4, or 5 grading levels based on your market requirements. Standard size classifications include:
- Grade 1: Below 4.5 cm
- Grade 2: 4.5 - 5.0 cm
- Grade 3: 5.0 - 5.5 cm
- Grade 4: 5.5 - 6.0 cm
- Grade 5: Above 6.0 cm
Custom grading sizes are available upon request to match specific market standards or buyer requirements.
Food-grade construction
All contact surfaces are made from food-grade 304 stainless steel and FDA-approved silicone materials. This ensures compliance with international food safety standards and prevents contamination during the sorting process. The smooth, non-porous surfaces are easy to clean and sanitize, reducing the risk of bacterial growth.
Universal functions and operational benefits
All-in-one design
Integrates elevator, roller-bar conveyor, and grading mechanism in one compact unit. This space-saving design reduces installation complexity and minimizes floor space requirements.
Robust and durable
Heavy-duty construction with reinforced frame and industrial-grade components ensures reliable operation even in demanding agricultural environments. Designed for continuous operation with minimal maintenance.
User-friendly operation

Low noise operation
Precision-engineered components and vibration-dampening mounts ensure quiet operation, creating a better working environment for operators and reducing noise pollution.
Gentle on produce
Soft silicone rollers and smooth transitions prevent bruising, cuts, or skin damage. Maintains garlic quality and appearance, preserving market value and shelf life.
Easy mobility
Built-in wheels allow easy repositioning within your facility. Locking casters ensure stability during operation while enabling quick relocation for cleaning or reconfiguration.
Convenient maintenance
Modular design with quick-access panels simplifies cleaning and maintenance. Removable grading screens and tool-free roller replacement reduce downtime and maintenance costs.
How does the garlic grading machine work?
Understanding the working principle helps operators maximize efficiency and troubleshoot any issues. The grading process follows these steps:
Step 1: Loading and elevation
Raw garlic is loaded into the hopper at ground level. The elevator system uses a belt or chain conveyor with cleats to lift the garlic to the grading height. The elevator speed can be adjusted to match the grading capacity and prevent overfeeding.
Step 2: Distribution
At the top of the elevator, garlic is evenly distributed onto the roller-bar conveyor. A spreading mechanism ensures single-layer feeding, preventing bunching and ensuring accurate grading.
Step 3: Size classification
The roller-bar conveyor transports garlic over grading openings. Smaller bulbs fall through the first set of openings, while larger bulbs continue to subsequent grading levels. The precision-engineered openings ensure consistent size classification.
Step 4: Collection
Graded garlic falls into separate collection bins or conveyors positioned beneath each grading level. This allows simultaneous collection of all size grades, streamlining downstream packaging or processing operations.
