What is a Count Filling Machine? Uses & Buying Guide
Introduction
In industries where “one extra” or “one missing” piece affects your bottom line and consumer trust, weight-based filling just doesn’t cut it. Whether you are bottling 30 high-value supplement capsules or bagging 50 stainless steel bolts, you need a Count Filling Machine.
Often referred to as Capsule Counters in the pharma world, these machines are the gold standard for high-speed, unit-accurate packaging.
What is a Count Filling Machine?
A Count Filling Machine is a specialized packaging system designed to dispense a precise number of solid items into a container. Unlike volumetric or net-weight fillers, these machines ignore the mass of the product and focus entirely on the individual unit.

How the Counting Process Works
Modern counters have moved far beyond simple mechanical gates. The process is a high-speed dance of vibration and light:
- Bulk Feeding: Product is loaded into a high-capacity hopper.
- Vibratory Separation: Three-stage vibratory trays gently separate the bulk product into single-file lanes.
- The “Eyes” (Detection): As the product drops, it passes through an infrared sensor array or a high-speed vision camera that registers the “break” in light.
- The Brain (Memory Flap): The machine’s computer tracks the count. Once the target (e.g., 60 units) is reached, a high-speed flap closes instantly, diverting the next units to a second filling head.
- Discharge: The counted batch drops into the bottle, which is then indexed away for capping.
Key Applications
Pharmaceuticals & Nutraceuticals: Hard gelatin capsules, soft gels, tablets, and caplets.
Hardware: Screws, plastic wall anchors, nuts, and bolts.
Food & Confectionery: Gumballs, wrapped candies, and premium chocolates.
Kitting: Counting out specific components for DIY furniture or assembly kits.
Choosing Your Technology: Types of Counters
Â
| Type | How it Works | Best For… |
| Electronic Counter | Uses IR sensors or Vision systems. | High-speed, multi-product versatility (pills to hardware). |
| Slat Counter | Mechanical “slats” with holes pick up individual pills. | Dedicated, ultra-high-speed pharmaceutical lines. |
| Disc Counter | A rotating glass or plastic disc with sized holes. | Smaller operations or very specific, uniform tablet sizes. |
Important: Know the Limitations
Before you buy, understand that counting machines have a different “enemy” than weight fillers:
Dust Sensitivity: In uncoated tablet environments, dust can coat sensors and cause “false counts.” Look for machines with integrated dust extraction ports.
Product Integrity: A counter cannot always tell the difference between a whole pill and two halves of a broken pill.
Speed vs. Accuracy: Moving too fast can cause “overlapping” where two items pass the sensor at once, appearing as one.

The Pre-Owned Buyer’s Checklist
If you are looking at a used machine on SurplusPack, keep these “Pro” factors in mind:
Sensor Health: Ask for a “count repeatability” test. A healthy machine should hit the exact count 100 times out of 100.
Changeover Simplicity: Does the machine require “change parts” (different trays/slats) for different products? Tool-less changeover is a massive time-saver.
Contact Parts: Ensure all parts touching the product are SS 316 (for pharma/food) and are easy to remove for sterilization.
Reject System: Does the machine have an automatic reject gate for bottles with incorrect counts? This prevents a small error from stopping your entire line.
