LSF-20: Powder Screw Dosing System with Integrated Screw Feeder
Semi-Automatic Gravimetric Screw Dosing System.
High-Precision Powder Screw Dosing System.
The Complete Solution for Precision Powder and Paste Filling
Why settle for inconsistent volumetric filling? The LSF-20’s gravimetric technology measures each dose by weight, not volume, eliminating errors caused by product density variations. This means you significantly reduce product giveaway, ensure compliance with weight regulations, and protect your brand’s reputation for quality. The integrated screw feeder makes this system a self-contained unit, ideal for feeding from bulk containers or upstream equipment.
| Feature Category | Description & Specifications |
|---|---|
| Dosing Principle | Gravimetric (weight-based) using a high-precision load cell for accuracies as fine as ±0.3% or better. |
| Drive System | Servo motor for precise control of the auger, enabling high-speed, repeatable dosing with strong torque. |
| Control System | PLC and touch screen interface for easy operation, recipe memory, and real-time monitoring of speed and filling volume. |
| Material Handling | Handles powders, micro-granules, and other bulk solids. An agitator in the hopper prevents clumping and bridging. |
| Hygienic Design | Constructed from Stainless Steel (AISI 304/SUS304), offering excellent corrosion resistance, chemical durability, and easy cleaning. |
| Integrated Screw Feeder | The receiving screw conveyor ensures a stable and continuous supply of material from a central source to the dosing hopper |
Engineered for Your Industry’s Demands
This doser is a versatile asset across multiple sectors, proving its value by handling challenging materials with ease.
-
Cosmetics & Personal Care: Perfect for filling salt scrubs, sugar scrubs, body powders, and other abrasive or delicate cosmetic ingredients with perfect portion control.
-
Food & Beverage: Reliably doses food powders, spices, and viscous products like peanut butter and nut pastes.
-
Specialty Goods & Chemicals: The ideal solution for portioning hookah tobacco (maassel), detergents, and various industrial powders.
How It Works: Simplicity Meets Sophistication
-
Feeding: The auxiliary screw feeder transfers product from the source into the main dosing hopper.
-
Preparation: The hopper agitator runs to keep the product uniform and prevent bridging.
-
Dosing: The operator places a container on the weighing platform and initiates the cycle. The precision stepper motor rotates the main screw for the exact amount needed to reach the target weight.
-
Completion: The cycle stops automatically, and the operator removes the perfectly filled container.
