Introduction to the Vormek Mechoris Visco Servo VFL-600
Products like Olivier salad, hummus, thick sauces, edible creams, chocolate spreads, honey, jams, and many prepared food items—due to their unique rheological behavior—require a fundamentally different filling technology. For such products, it is not just about transferring material into a container; it is about preserving texture, preventing particle damage, achieving high accuracy, meeting hygiene requirements, and ensuring repeatability in production.
The Mechoris Visco Servo VFL-600 represents the next generation of piston cylinder fillers. Powered by advanced servo motor technology, it delivers a new level of precision, control, and flexibility for filling viscous products.
The Challenges of Filling Viscous and Semi‑Solid Products
Many food products possess characteristics that make conventional filling systems inadequate:
| Challenge | Description |
|---|---|
| High viscosity | Difficult flow; requires greater suction and injection force |
| Suspended particles or solid pieces | Risk of clogging and particle damage |
| Temperature sensitivity | Viscosity changes with temperature fluctuations |
| Structural fragility | Texture degradation from excessive mechanical stress |
| High weight accuracy requirements | Very tight weight tolerance for high-value products |
In such cases, choosing the right filling technology directly impacts final product quality, production efficiency, and line profitability.
Why Servo Drive Technology?
In many older systems, piston movement is driven by pneumatic systems. While functional, these systems have limitations in precision, speed control, and flexibility.
The Mechoris Visco Servo VFL-600 uses industrial servo motors to control piston movement, offering:
| Advantage | Description |
|---|---|
| High precision | Millimeter-precise piston positioning → uniform fill volume, reduced weight tolerance, minimized waste |
| Full speed and acceleration control | Adjustable suction and injection speeds; controlled acceleration prevents sudden impact on delicate products (especially those with particles) |
| Recipe management | Storage and recall of fill volume, speed, timing, and parameters for each product → instant changeover with a single selection |
| Excellent repeatability | Consistent accuracy over time → the first and thousandth container have identical fill volume |
Operating Mechanism
At the heart of the VFL-600 is the cylinder and piston assembly, controlled by a servo motor. The system operates in two main phases:
Phase 1: Product Suction
- Piston moves backward
- Control valve opens the inlet path
- Product enters the cylinder from the hopper
- Suction volume precisely matches the programmed piston stroke
Phase 2: Product Discharge
- Piston moves forward
- Inlet path closes
- Outlet path to the nozzle opens
- Product is dispensed into the container at controlled speed
Thanks to precise servo motor control, the discharge process is completely uniform and shock-free.
Specialized Design for Products with Particles
A key advantage of the VFL-600 is its ability to handle products containing solid particles. To achieve this:
- Material flow path diameters are appropriately sized
- Nozzles are designed based on particle size
- Pistons are engineered to match product behavior
- Particle clogging risk is minimized
This makes the machine ideal for products such as Olivier salad, hummus, and sauces containing vegetable pieces.
Main Components
| Component | Description |
|---|---|
| Product hopper | Custom-designed; can be equipped with agitator, heating system, level control, and temperature sensor |
| Texture-appropriate agitator | Prevents settling and maintains product uniformity throughout the process |
| Cylinder and piston | The heart of the filling system; designed for product viscosity, fill volume, and product type |
| Specialized nozzles | Customized based on container type, product characteristics, and production speed; can be equipped with anti-drip, bottom-up filling, and foam/air bubble prevention systems |
Hygienic Design – Compliant with Food Industry Standards
In the food industry, hygienic design is a necessity. The Mechoris Visco Servo VFL-600 is built according to hygienic engineering principles:
- Full 304 or 316 stainless steel construction
- No dead zones or blind spots
- Quick disassembly capability
- Easy cleaning
- CIP-ready (Clean-In-Place compatible)
- Prevents food residue accumulation
Design Flexibility
No two products are exactly alike. That is why the VFL-600 is fully customizable.

|---|---|
| Number of nozzles | 1, 2, 4, 6, 8, or more based on production capacity |
| Fill volume | From a few milliliters to several liters |
| Hopper capacity | Matched to line requirements |
| Agitator type | Matched to product texture and viscosity |
| Heating system | For products requiring hot filling |
| Control type | Timer-based, flow-based, weight-based |
| Automation level | Semi-automatic to fully automatic with PLC |
