A semi-auto weight filler for 100-1000 gram packages is a machine that uses a load cell to weigh and dispense granular or powdered materials into a bag or container. It operates semi-automatically, with an operator placing the container, but the machine handles the weighing and dispensing based on pre-set weight parameters. These fillers are built with stainless steel for durability and hygiene, have a variable packing speed depending on the material, and are used for products like grains, seeds, powders, and snacks. 

Key features and components

• Weighing mechanism: Uses a load cell-based system with a digital display to accurately measure the weight of the dispensed product.
• Weight range: Capable of filling between 100 and 1000 grams per cycle.
• Filling speed: Varies by material but typically ranges from 6 to 20 fills per minute (or 360 to 1200 bags per hour).
• Material construction: Often built with stainless steel for hygiene and durability.
• Operator interaction: An operator places the container under the discharge nozzle. The operator may also need to initiate the cycle, and the machine handles the weighing and filling automatically.
• Power: Typically runs on standard voltage, like 220V or 110V. 

Common applications

• Food products: Grains, rice, pulses, sugar, salt, tea leaves, coffee beans, nuts, seeds, and snacks like popcorn.
• Powders: Flour, spices, and certain chemical powders.
• Other materials: Fertilizers, pet food, hardware accessories, and other granular materials. 

Working principle

1. The operator places an empty bag or container under the discharge nozzle.
2. The desired weight (between 100 and 1000 grams) is set on the control panel.
3. The machine starts filling the container automatically based on the load cell reading.
4. Once the target weight is reached, the filling stops, and the operator removes the filled container.
5. The process repeats for the next container.
