In-Depth Details
Operational Workflow
The workflow is optimized for speed and simplicity. Material is lifted via an elevator into a storage bin, which then feeds the machine's two weighing hoppers. These hoppers operate cyclically: as one is dispensing its accurately weighed contents into a bag, the other is being filled and weighed for the next cycle. An operator's primary role is to manually place a pre-made bag onto the filling spout. The machine takes over the filling, and the filled bag can then be conveyed to an automatic sealing station, completing the packaging process.

Frequently Asked Questions (FAQ)
Q1: What makes the dual-hopper system better for my production?
A: The dual-hopper weighing system is the key to its high speed. While a single-hopper machine must stop filling to weigh, our dual system performs these tasks simultaneously. One hopper discharges a pre-weighed batch while the other is being filled and weighed. This parallel processing eliminates the weighing bottleneck and nearly doubles potential output.
Q2: Is this machine suitable for very fine powders?
A: This machine is optimized for granular materials like grains, beans, and seeds. While it can handle some coarse powders, very fine or dusty powders are better suited for our specialized auger-filler or net-weigh powder packing machines. Please contact us to discuss your specific material.
Q3: What level of automation does this machine provide?
A: This is a semi-automatic machine. It automates the most critical and time-consuming part of the process: accurately weighing the product at high speed. The operator's main task is placing the bag at the filling station. For a fully automated line, this machine can be integrated with an automatic bag feeder and sealing conveyor.
