Hebei Julite Sorting Technology Co., Ltd. offers its Gravity Table for Grains, a precision machine designed to separate grain batches—wheat, rice, barley, corn, and more—based on subtle density and shape variations. The gravity table enhances overall grain quality by removing light, immature, or broken kernels.
Separation Mechanism
Material is evenly fed onto a slightly inclined, reciprocating deck covered with deck cloth or perforated plate. Below the deck, a plenum chamber supplies air through the cloth. The combination of deck vibration, inclination, and air lift causes the grain to stratify: heavier, sound kernels travel down the deck toward the lower side, while lighter, defective grains ride the airstream upward. At the outlet, segregated streams exit via separate chutes.
Adjustable Controls
Deck Amplitude and Speed: Vary the vibration intensity and oscillation frequency to suit grain type and desired separation.
Deck Angle: Fine‑tune the gradient to control migration speed of heavy versus light fractions.
Airflow Volume: Adjust lift force to separate kernels by density differences, typically in the range of 0.02–0.2 g/cm³.
Construction and Materials
Sturdy Frame: Welded steel supports maintain deck alignment under continuous operation.
Deck Surface Options: Interchangeable deck cloth or perforated plates with different hole patterns allow customization for various grains.
Corrosion Protection: All grain‑contact surfaces are stainless steel or coated with FDA‑approved finishes.
Operational Advantages
Precision Separation: Capable of refining grain lots to meet milling or malting specifications by removing foreign seeds, broken kernels, and light impurities.
Low Breakage Rates: Gentle deck motion and airflow preserve kernel integrity.
Flexible Capacity: Models process between 1 t/h and 15 t/h, accommodating both laboratory and industrial scales.
Energy Efficiency: Moderate power draw for deck vibration and blower, lower than full-scale aspiration systems.
Applications
Wheat and Barley Malting: Ensures uniform kernel density for consistent steeping and germination.
Rice Milling: Improves head‐rice yield by removing chalky or immature kernels.
Corn and Seed Processing: Polishes seed lots by discarding under‐developed kernels.
Specialty Grains: Refines quinoa, buckwheat, or millet batches for premium markets.
Hebei Julite Sorting Technology Co., Ltd. provides comprehensive support for its Gravity Tables: site layout guidance, equipment commissioning, operator training, and preventive maintenance programs, guaranteeing sustained separation performance and product quality.
