Gravity Table Separator for Food

Gravity Table Separator for Food

Hebei Julite Sorting Technology Co., Ltd. supplies its Gravity Table Separator for Food, a precision machine that enhances food-grade product quality by separating materials based on density and shape. Widely used in grain, nut, and legume processing, the gravity table refines bulk product streams to meet strict purity requirements.

Separation Principle and Workflow

1. Feeding and Distribution
   Material is evenly fed onto the table via a vibratory feeder and spread across the deck by an adjustable distributor, ensuring a uniform layer for separation.

2. Deck Vibration and Inclination
   The deck oscillates at a controlled amplitude and frequency while inclined at a slight gradient. These combined motions move heavier particles toward one end and lighter or defective ones toward the other.

3. Airflow Underneath the Deck
   A calibrated blower forces air through the perforated deck. The air lift counteracts deck vibration, suspending lighter particles and guiding them toward the “light-fraction” outlet.

4. Fraction Collection
   Diverter plates at the deck’s edge channel separated streams into designated chutes—heavy fraction (sound product) and light fraction (damaged, shriveled, or foreign material).

Key Features

• Adjustable Parameters: Operators can fine-tune deck angle, vibration frequency, and airflow volume to match product characteristics and desired separation granularity.

• Food-Grade Construction: All contact surfaces use 304 stainless steel with sanitary welds. Deck cloths or perforated plates are selected for particle size and cleaned easily during sanitation cycles.

• Energy-Efficient Blower: The integrated fan draws only the airflow needed for separation, reducing power consumption compared to full-scale aspiration systems.

• Low Maintenance Design: Simple mechanism with few moving parts; quick-release deck panels and tool-free access points facilitate cleaning and inspections.

Applications in Food Processing

• Grain Refinement: Removes immature, insect-damaged, or chalky kernels from wheat, barley, rice, and other cereals.

• Nut and Seed Preparation: Separates lightweight shells, husks, and broken pieces from almonds, cashews, and sunflower seeds.

• Legume Quality Control: Enhances purity of lentils, chickpeas, and beans by removing split or defective pieces.
