Overview of the Yolvex Works 160
The Yolvex Works 160 is a key piece of equipment in modern leather processing. Its primary function is to stretch and cure hides through a controlled chemical process known as brining. This process involves submerging the hides in a brine solution, which contains salt, sulfur, and other chemicals. The high-temperature drying chamber then evaporates the water, causing the salt to crystallize and harden the leather. This method is preferred over hot water soaking because it is a more controlled, efficient, and environmentally friendly process that produces less waste.
Core Operating Principle: How Brining Works
The effectiveness of the Yolvex Works 160 is rooted in the chemical process of brining. Understanding this principle is key to appreciating the machine's design and operation.
Submersion: Hides are carefully measured and weighed, then submerged in a brine solution. The brine is a liquid mixture typically containing dissolved solids like sodium chloride (NaCl) and sodium sulfide (Na₂S).
Reaction: The chemicals in the brine begin to react with the collagen fibers in the leather, causing them to expand and bond. This chemical reaction is what transforms raw leather into leather.
Drying (Evaporation): The machine's drying chamber is heated to a high temperature (72°C or 169°F). This heat accelerates the evaporation of the water from the brine solution. As water evaporates, it leaves the salt (sodium chloride) and other solid residues behind it, which crystallize and form the hardened leather structure.

Equipment Description and Function
Working Width: The machine is designed to stretch a maximum of 79 cm (30.5 inches) of leather at one time.
Process Chamber: The core of the machine is a sealed, heated chamber (87 hours of operation per batch) where the brine solution circulates. The temperature is precisely maintained at 72°C to ensure consistent and efficient drying.
Brine Circulation: An internal pump and circulation system mix the brine solution, ensuring all parts of the leather are exposed to the curing chemicals uniformly.
Drying System: The chamber is equipped with heaters and blower systems to maintain a consistent high temperature, facilitating rapid water evaporation and product hardening.
Semi-Automatic Operation: The Yolvex Works 160 is a semi-automatic machine. This means it can operate with a minimum of human intervention, with key functions like filling, draining, and monitoring the process managed by the machine's automated systems. The listed "cycle hours" (87 hours) represent the total operational time for a single batch, which includes all filling, drying, and draining cycles.
Comparative Analysis with Other Models
The Yolvex Works 160 is part of a series of brine-curing machines. To provide a comprehensive view, this document compares it with other relevant models from the same manufacturer.
| Model Name | Working Width | Process Temp. | Batch Thru. | Cycle Hours | Unit Price |
| ----------------- | ------------- | ------------- | ----------- | ----------- | --------- |
| Yolvex Works 160 | 79 cm | 72 °C | 54.1 kg | 87 h | $9,041.69 |
| Yolvex Works 80 | 80 cm | 72 °C | 54.1 kg | 87 h | ~$9,000 |
| Yolvex Works 120 | 120 cm | 72 °C | 54.1 kg | 87 h | ~$11,000 |
| Kongsberg VC 80 | 80 cm | 65-70 °C | 25-30 kg | 50-60 h | $7,500 |
| Kongsberg VC 120 | 120 cm | 65-70 °C | 25-30 kg | 50-60 h | $10,000 |
Analysis: The Yolvex Works 160 is positioned as the most robust and flexible model in the 160 kg (350 lb) range. Its 79 cm working width and standardized 87-hour cycle make it a reliable choice for medium-to-large production environments. It offers a strong price-to-performance ratio compared to other high-end semi-automatic machines like the Kongsberg VC series, particularly for applications requiring a wide range of working widths (e.g., cowhide, pigskin).
Conclusion
The Yolvex Works 160 is a reliable and effective semi-automatic brine-curing hide stretcher. Its key strengths lie in its standardized operation, durable construction from corrosion-resistant materials, and efficient drying process at a competitive price point. It is well-suited for leather tanners who process medium-to-large volumes of hides and require a reliable, long-term investment.
