Description
The High Precision Garlic Bulb Sorting Machine Drum Type For Sale is an essential piece of equipment for modern agricultural processing, specifically engineered to handle the unique physical characteristics of the garlic bulb. Unlike flat-bed graders that can cause bruising, this drum-type system is designed to sort whole garlic bulbs by diameter with surgical accuracy. It addresses the industry’s need for uniform sizing in retail packaging and seed selection, ensuring that every garlic bulb is categorized without damaging its delicate, papery outer skins. For exporters and wholesalers, this machine represents the perfect balance of high-volume throughput and meticulous quality control.

Garlic Bulb Sorting Machine Working Principle
The High Precision Garlic Bulb Sorting Machine Drum Type operation relies on a series of rotating stainless steel drums with progressively larger circular apertures. As the garlic bulbs enter the first stage of the rotating drum, they are gently tumbled. Smaller bulbs fall through the initial precision-drilled holes onto a collection conveyor, while larger bulbs move forward to the next section. The drum’s rotation speed and inclination are finely tuned to ensure that each garlic bulb has ample opportunity to find its matching size slot without being forced or jammed. This mechanical “screening” process provides a 360-degree size check, which is far more accurate for the irregular shape of a garlic bulb than traditional optical or weight-based systems.
Garlic Bulb Grading Machine Advantages
-
Superior Grading Accuracy: The circular holes in the drum are laser-cut to provide high-precision sorting, ensuring a size deviation of less than 1mm per garlic bulb.
-
Zero Damage Processing: The gentle tumbling action of the drum type system prevents the “clove separation” often caused by more aggressive vibration-based sorters.
-
Massive Throughput Capacity: Capable of processing several tons of garlic bulbs per hour, significantly outperforming manual labor or small-scale graders.
Garlic Sroting Machine Features
-
Multi-Stage Drum Configuration: Features 4 to 6 grading levels, allowing the garlic bulb to be sorted into multiple precise diameter categories in a single pass.
-
Food-Grade SUS304 Construction: The entire contact surface is made of polished stainless steel to prevent contamination and ensure smooth passage for each garlic bulb.
-
Adjustable Rotation Speed: Equipped with a frequency inverter that allows operators to control the drum speed based on the moisture content and skin fragility of the garlic bulb.
-
Soft-Drop Discharge Chutes: Each sorting grade is equipped with a padded or angled chute to minimize the impact when the garlic bulb exits the machine.
Garlic Grading Machine Benefits
-
Increased Market Premium: Uniformly sized garlic bulbs command a much higher price in international supermarkets and professional culinary markets.
-
Reduced Labor Overhead: A single garlic bulb sorting machine can replace 10-15 manual workers, drastically lowering long-term operational costs.
-
Optimized Seed Selection: Provides the high-precision sorting required to separate the best garlic bulbs for replanting, improving future crop yields.
Evidence
-
Industrial Durability: Our drum-type graders are built for 24/7 operation during the peak garlic harvest season with minimal maintenance.
-
Global Export Standard: This garlic bulb sorting machine meets all EU and USDA food processing equipment standards for hygiene and safety.
-
Proven Performance: Trusted by major garlic exporters in China, Spain, and Argentina to handle diverse varieties from white to purple garlic bulbs.
