Feature of N-Pack Screw Type:

High Speed and Stability: Uses 2-axis integrated screws type with large and small diameters set in coaxial. It is filled to fixed amount (appropriate value) before the set values in a short time by big and small screws. After a fixed amount is reached. The remaining amount is filled with high precision by small diameter screw only.
Flexibility: The blade pitch can be changed according to different raw materials.
Clogging Prevention: Bridge of the powder can be prevented by the wings built inside the hopper.
Suitable for Fine Powder: Ideal for fine powder such as medical supplies, pigments, toner, flour, rice flour, etc.
Easy Maintenance: Designed to allow dismantling without tools for cleaning.

Weighing and filling machine: N-pack scale

Internal Structure and Principle:

Two-Step Material Feeding: In the first step, the machine rapidly fills the material up to the set quantity using both the large and small screws. Subsequently, the remaining amount is filled with high precision using only the small screw.
Microcomputer Control: The system uses a microcomputer and a Load Cell to ensure accurate weight measurement.
Auto-Zero Function: It is equipped with the Auto-Zero function and can measure the Net Weight (omitting the Tare Weight) starting from "zero," thus preventing accumulative error.
