Case Study: Pneumatic Vibratory Feeder with Timed Dispense for Powder Filling into Jars

Problem

A fine powder manufacturer needed a consistent, low-maintenance method for filling individual jars with precise quantities of product. Their existing process lacked repeatability, required frequent operator adjustments, and led to overfills, waste, and inconsistent presentation, especially problematic for small-batch runs.

Situation

To streamline the filling process, the manufacturer turned to MARTIN® for a simple, reliable solution. The answer was a pneumatic vibratory feeder equipped with an electronic timer and pneumatic solenoid. When triggered, the solenoid opened to allow compressed air to power the vibrator for a set duration, creating a controlled flow of powder into each jar. Once the timer cycle completed, the solenoid closed, halting the vibration and stopping product flow — ensuring clean, consistent fills.

The system was designed for ease of use and required minimal operator input. Fill durations could be quickly adjusted via the timer to accommodate different jar sizes, offering flexibility without the need for complex automation or advanced controls.

Solution

With the new E-Z™ Vibratory Feeder system in place, the manufacturer was able to:

• Dispense precise powder volumes into each jar with minimal supervision
• Avoid overflows and reduce product waste through timed vibration control
• Quickly adjust fill times to suit varying container sizes
• Automate efficiently without investing in elaborate control systems

The result was a dependable, user-friendly powder filling solution that improved accuracy, reduced labor, and supported both small-batch and production-scale needs with ease.
