Executive Summary
A specialty chemical manufacturer required a fully automated, GMP-oriented and industrial-grade Gum Rosin & Turpentine Processing Plant to manufacture premium Gum Rosin, Gum Turpentine Oil (GTO), and value-added resin derivatives from natural pine oleoresin.
The customer required a turnkey processing facility capable of maximising gum rosin recovery, producing high-purity gum turpentine oil, minimising thermal degradation, reducing utility consumption, and consistently manufacturing export-grade products meeting international quality standards.
Mechotech successfully designed, engineered, manufactured, supplied, installed, and commissioned a Gum Rosin Processing Plant integrating advanced oleoresin melting, filtration, vacuum distillation, turpentine recovery, resin purification, automatic packing, and intelligent PLC-SCADA automation.
Customer Background
The customer manufactures specialty resin products for adhesive manufacturers, paint & coating companies, printing ink manufacturers, rubber processing industries, paper & packaging industries, pharmaceutical companies, fragrance manufacturers, and chemical exporters.

Process Flow
Process Description
Raw Material Preparation
Crude pine oleoresin is received, inspected, and melted in jacketed stainless steel melting vessels under carefully controlled temperature conditions to prevent degradation.
Filtration
The molten oleoresin passes through multiple filtration stages to remove:
- Bark particles
- Dirt
- Sand
- Wood fibres
- Mechanical impurities
The filtration process significantly improves final gum rosin quality.
Vacuum Distillation
Filtered oleoresin enters specially designed vacuum distillation columns where volatile gum turpentine oil is separated from non-volatile gum rosin.
The process provides:
- Low thermal degradation
- Reduced oxidation
- Energy-efficient operation
Gum Turpentine Recovery
Recovered vapours are condensed using high-efficiency condensers to obtain premium Gum Turpentine Oil suitable for industrial and fragrance applications.
Rosin Purification
Remaining molten rosin undergoes polishing filtration before final storage and packing.
The purification system ensures:
- Better colour stability
- Low ash content
Automatic Packing
The finished gum rosin is packed into:
- Steel Drums
- Fibre Drums
- HDPE Bags
- Jumbo Bags
- Customised Export Packaging
Quality Standardisation
Gum Rosin:
- Colour Grade (WW, WG, X)
- Acid Value
