I'm in need of a semi-automatic linear weigher specifically for roasted coffee beans. The machine should have a filling range between 500g and 3000g, with a daily capacity around 200 kg. We're looking for a system that allows manual bag placing, avoiding any automatic bagging processes. Key features I require include no auger system since it's for beans, weighing capability rather than volumetric, and construction from food-grade stainless steel (SS304). Please provide videos showcasing the machine in operation with coffee beans, along with comprehensive specifications, pricing details, and lead time for delivery.
