In the food packaging industry, handling strawberry jam with large, whole fruit chunks is a sophisticated task. How do you maintain the integrity of the fruit while ensuring high-speed, drip-free precision?

Recently, Navan, a leading filling machine manufacturer, partnered with a premium food producer in Russia to implement a state-of-the-art jam filling machine line specifically designed for glass jars.

The Challenge: Particles & Precision

Our Russian client specializes in high-end preserves. Their signature strawberry jam contains fruit pieces up to 15-20mm. They faced three primary hurdles:

  1. Fruit Damage: Standard pumps often crushed the strawberries, turning premium jam into puree.
  2. Inconsistent Filling: The high viscosity and uneven distribution of particles caused weight fluctuations.
  3. Glass Jar Durability: The line needed to handle heavy glass jars with a specialized vacuum capping process to meet Russian food safety standards.

The Navan Solution: A Specialized Jam Filling Machine

To solve these issues, Navan engineers customized a Piston-Driven Jam Filling Machine with several key features:

1. Large-Bore Rotary Valve Technology

Unlike standard valves, our rotary valve design allows large strawberry particles to pass through without being sheared or crushed. This ensures that when the consumer opens the jar, they see whole, beautiful fruit.

2. Servo-Motor Precision

By using servo-driven pistons, we achieved a filling accuracy of ±1%, even with varying fruit-to-syrup ratios. This reduces product waste and ensures every glass jar meets export standards.

3. Integrated Glass Packaging Line

The solution wasn’t just a filler; it was a complete ecosystem including:

  • Automatic Glass Jar Sterilization
  • Vacuum Steam Capping (ensuring a longer shelf life without preservatives)
  • Automatic Labeling and Coding

From Factory Floor to Russian Tables

The success of this project is best captured in our latest case study video:

  • Client Testimonial:
