Introduction to the Vormek Mechoris Visco VFL-500
Filling thick, viscous, or chunky products—such as Olivier salad, mayonnaise with vegetable pieces, or temperature-sensitive formulations—has always been a challenge in food production lines. Conventional fillers often lack precision, damage product texture, or cannot be cleaned thoroughly.
The Mechoris Visco VFL-500 from Vormek’s ViscoFill series is a pneumatic piston cylinder filler specifically engineered to solve these problems. Using compressed air to drive a piston within a cylinder, it delivers precise, controlled volumes of product directly into containers.
Key Applications
- Ideal for thick, semi-solid, chunky, or viscous products requiring specific filling temperatures
- Fully customizable—nozzle, piston size, and hopper can be tailored to your product
- Fully hygienic—all product-contact components are manufactured from corrosion-resistant stainless steel and are easily disassembled for cleaning
1. The Challenge of Filling Thick and Semi‑Solid Products
Products with high viscosity, semi-solid structure, non-homogeneous composition, or varying particle sizes require specialized filling technology. Selecting the right equipment depends on several factors:
| Selection Factor | Description |
|---|---|
| Product viscosity | Piston type and nozzle design must match product behavior; sufficient power is essential |
| Product composition and particle size | The system must accommodate various textures; design depends heavily on product characteristics |
| Container size | Cylinder size and piston stroke length selected based on container volume and fill amount |
| Production capacity | Multi-nozzle models recommended for high-output lines |
| Line speed | Multi-piston fillers with precise volume and timing control are optimal for continuous production |
| Ease of cleaning and maintenance | All product-contact parts must be easily disassembled; design must prevent residue buildup |
| Technical support and spare parts | Vormek’s experienced service team and parts supply are always available |
| Compatibility with existing line | Dimensions, electrical system, automation, and mechanical integration must align with current setup |
The Mechoris Visco VFL-500 is designed to address all of these requirements.
2. Pneumatic Piston Cylinder Operating Mechanism
At the heart of this machine is a reciprocating piston and cylinder driven by a pneumatic system. Pneumatic power offers high force, low maintenance costs, and excellent reliability for industrial environments.
The piston movement consists of two main phases:
Phase 1: Suction
- Piston moves backward
- Three-way valve opens the inlet path from the hopper
- Product flows into the cylinder in a controlled manner
- Inlet volume is precisely determined by piston stroke length
Phase 2: Discharge (Filling)
- Piston moves forward
- Three-way valve closes the inlet and opens the outlet path to the nozzle
- Product is dispensed into the container at controlled pressure
Key Point: Each nozzle is equipped with an independent piston, ensuring accurate performance, preventing cross-nozzle interference or leakage, and enabling independent adjustment of each nozzle.

4. Technical Selection Criteria
From a mechanical and food engineering perspective, selecting the right piston filler depends on:
| Selection Factor | Technical Consideration | Priority |
|---|---|---|
| Product viscosity | High-viscosity products require more powerful pistons, appropriate cylinder diameter, and shorter flow paths | ⭐⭐⭐⭐⭐ |
| Particle size and composition | Chunky products (e.g., Olivier salad) require wide-opening nozzles, clog-free paths, and specialized piston design | ⭐⭐⭐⭐⭐ |
| Container size | Fill volume, piston stroke length, and cylinder diameter must match container capacity | ⭐⭐⭐⭐ |
| Production capacity | Multi-nozzle models with independent pistons recommended for high output | ⭐⭐⭐⭐ |
| Line speed | Multi-piston fillers with precise volume and timing control are optimal for continuous lines | ⭐⭐⭐⭐ |
| Cleaning and maintenance | All product-contact parts must be easily disassembled; design must prevent residue buildup | ⭐⭐⭐⭐⭐ |
| Technical support and spare parts | Experienced service team and standard parts availability | ⭐⭐⭐⭐ |
| Existing line compatibility | Dimensions, electrical, automation, and mechanical integration must align | ⭐⭐⭐⭐ |
5. Hygienic Design and Cleanability
In the food industry, hygiene is not a feature—it is a requirement. The Mechoris Visco VFL-500 is designed with hygienic engineering principles:
| Hygienic Feature | Description |
