Components: Vacuum pump, vacuum tank, water supply tank, vacuum chamber, bag control mold, weighing control system, intelligent digital vacuum gauge monitoring system, automatic feed valve control system, PLC program total control system, text parameter setter. Working Principle: The vacuum system provides sufficient vacuum. When vacuum in the chamber reaches set value, feed proportional valve opens to let material in by pressure difference. Material fills the bag in vacuum chamber. When target weight is reached, valve closes. Packaging occurs in fully sealed vacuum state. Features: 1. Vacuum chamber withstands strong vacuum (max -88Kpa), fast packaging, zero gas in bag. 2. Weighing system with intelligent vacuum gauge precisely controls weight via automatic valve. 3. PLC control with few external components, simple operation, low failure rate. 4. Fully sealed vacuum packaging, no dust. 5. Explosion-proof control available for conductive materials. Suitable Materials: Fumed silica (white carbon black), modified fumed silica, nano-precipitated silica, ultra-fine pigment carbon black, modified nano-powders, various light and high-air-content powders. Technical Parameters: Model JKF-159C. Speed 50-70 bags/h (10kg). Range 3-50kg. Accuracy ±0.2-0.5%. Power AC380V/50Hz, 7.5kW. Air supply 0.6MPa, 20NL/min. Weight 1200kg. Dimensions 1250×1750×2200mm.
