Two-Stage Feeding (Minimum Height) Vertical Packaging System

Eliminating Filling Inaccuracy and Operator Dependency

Processing granular and powder materials often faces the challenge of weight inconsistency and material bridging at low fill heights. Standard vertical packaging systems struggle to maintain ±0.5g per bag at minimal headroom setups.
The TSF-VPS1200 is engineered to solve this by utilizing dual-stage feeding with precision PLC control. This ensures accurate fills, reduced manual intervention, and consistent throughput even in confined production spaces.

Engineering Logic & Technical Advantages

• Feature 1: Dual-Stage Feeding Mechanism

  • The Engineering: Two-stage screw and vibration feeding system capable of adjusting feed rate from 10–50 kg/min.

  • The Impact: Prevents bridging and ensures uniform flow into bags, reducing overfill by up to 3% per batch.

• Feature 2: Compact Vertical Design

  • The Engineering: Supports minimum installation height of 2.2 meters, made of SUS304 stainless steel with 3mm thickness.

  • The Impact: Allows installation in low-ceiling workshops while meeting HACCP and FDA compliance.

• Feature 3: PLC-Controlled Precision

  • The Engineering: Siemens S7 PLC monitors weight, screw torque, and vibration amplitude in real time.

  • The Impact: Reduces operator oversight by 40%, ensuring consistent ±0.5g accuracy per bag.

• Feature 4: Multi-Nozzle Filling System

  • The Engineering: 2-3 adjustable nozzles with pneumatic gates and 25ms response.

  • The Impact: Enables simultaneous filling, increasing capacity to 1200kg/hr with reduced downtime.

• Feature 5: Anti-Blockage Auger

  • The Engineering: 40mm diameter auger with variable pitch, driven by 0.75kW high-torque motor.

  • The Impact: Maintains continuous material flow, even for hygroscopic powders, avoiding production stoppages.

Production Workflow & Integration

The TSF-VPS1200 is designed to integrate seamlessly into granular & powder packaging lines:

1. Intake: Receives material from upstream hopper or pneumatic conveyor.

2. Processing: Accurately feeds and dispenses material using dual-stage screw and vibration system while monitoring load cell readings.

3. Discharge: Automatically transfers filled bags to the sealing or downstream conveyor system, minimizing manual labor.
