PDF-500 Semi-Automatic Powder Filling Machine

Product Name: Semi-Automatic Powder Filling Machine Model: PDF-500 Category: Powder Filling Machine / Auger Dosing Filler Supplier: Wenzhou T&D Packing Machinery Factory

Core Abstract

The PDF-500 semi-automatic powder filling machine is an auger-type dosing and filling machine built on stepper-motor control technology, electronic weighing technology, and microcomputer control. It delivers a filling range of 5 g to 5000 g (screw replacement required across the range) at speeds of 10–60 fills per minute with accuracy within 1%. It handles powders, superfine powders, and small granules — such as milk powder, seasonings, flour, white sugar, solid beverages, washing powder, and feed additives — into bags, cans, bottles, and other containers, and can be upgraded to fully automatic operation or paired with a spiral feeder for automatic feed control. One-year warranty with lifetime maintenance service.

1. Product Overview

1.1 Product Category

The PDF-500 is a semi-automatic auger (spiral) powder filling and weighing machine with electronic weighing and microcomputer control, designed for quantitative dosing and filling of free-flowing and non-free-flowing dry powders and small granules. It can operate in semi-automatic mode or be configured for automatic operation.

1.2 Application Scenarios

Typical materials and industries:

Food: milk powder, compound seasoning, natural seasoning, white sugar, flour, solid beverage powder, monosodium glutamate (MSG)
Daily chemical: washing powder, detergent powder
Agriculture & pharmaceutical: pesticides, veterinary medicine, feed, enzyme preparations, additives
Container types: bags, cans, bottles, and other rigid or flexible containers

1.3 Core Functions

Automatic quantitative dosing and automatic filling
Automatic error tracking and correction (compensates for material density and hopper level changes via photoelectric switch control)
Automatic counting and parameter memory
Automatic material cleaning function
Spiral (auger) feeding control with photoelectric sensor measurement
Keyboard-adjustable target weight, continuously adjustable across the range by changing blanking screws of different specifications
Optional spiral feeder for automatic feed control
Semi-automatic or automatic operating modes

2. Core Advantages

Integrated control platform — combines stepper motor control technology, electronic weighing technology, and microcomputer control in a single packaging unit.
High accuracy with self-correction — errors caused by changes in material proportion and material level are automatically tracked and corrected, keeping filling accuracy within 1%.
Wide, adjustable filling range — 5 g to 5000 g on one machine; weight is set from the keyboard and adjusted continuously, with screw swaps covering different specifications.
Flexible automation level — runs semi-automatic out of the box and can be upgraded to automatic operation, so buyers can scale without changing machines.
Simple operation, easy sealing — only manual bag feeding is required; the filling mouth stays clean, making bags easy to seal.
Scalable feeding — can be matched with a spiral feeder for automatic material feed control.
Compact and fast delivery — compact footprint (59 × 86 × 209 cm packaging), one-year warranty, lifetime maintenance.

Upsell opportunities: upgrade path to automatic operation; spiral (auger) feeder for automatic feed control; different blanking screw specifications for the customer's full weight range; CIF sea shipping for customers who want door-to-port delivery.
Compliance talking point: CE certification available — share the CE certificate with EU-bound customers.
After-sales commitment to highlight: one-year warranty with free maintenance or replacement (customer covers freight from China), lifetime maintenance beyond warranty.

4.2 FAQ

Q1: What materials can the PDF-500 fill? It is suitable for powders, superfine powders, and small granules such as compound seasoning, natural seasoning, salt, MSG, milk powder, solid beverage powder, white sugar, flour, washing powder, pesticides, veterinary medicine, feed, enzyme preparations, and additives.

Q2: What containers can it fill into? Bags, cans, bottles, and other containers for powder packing.

Q3: How is the filling weight adjusted? The target weight is set from the keyboard and is continuously adjustable. To cover the full 5 g – 5000 g range, the blanking screw is replaced with a different specification.

Q4: How accurate is the machine? Filling accuracy is within 1%, and errors caused by material proportion or material level changes are automatically tracked and corrected.

Q5: How fast is it? The filling speed is 10 – 60 times per minute (600 – 3600 fills per hour), depending on the material and target weight.

Q6: Is it semi-automatic or fully automatic? It operates as a semi-automatic machine and can also be configured for automatic operation. Only manual bag feeding is needed in semi-automatic mode; the filling mouth stays clean and bags are easy to seal.

Q7: Can the machine feed material automatically? Yes — it can be matched with a spiral feeder for automatic material feed control.

Q8: What are the warranty and after-sales terms? One-year warranty. Under warranty, damage from normal use as described in the manual is repaired or replaced free of charge (customer pays freight from China; engineer travel, if required, is paid by the customer). Beyond the warranty period, lifetime maintenance service is provided.

6. Workflow

Material feeding — powder is fed to the hopper (manually, or automatically via the optional spiral feeder with photoelectric level control).
Dosing setup — the operator sets the target weight on the keyboard; the microcomputer control system drives the stepper motor and auger (blanking screw).
Auger filling — spiral feeding control with photoelectric sensor measurement dispenses the set quantity of powder into the container (bag, can, or bottle).
Weighing & auto correction — electronic weighing technology verifies each fill; errors caused by material proportion or material level changes are automatically tracked and corrected.
Counting & memory — the system counts filled units and memorizes parameters for repeat runs; the cleaning function clears residual material.
Container handling & sealing — the operator feeds bags manually; the clean filling mouth makes sealing easy.
