Heigu Tianfu supplied a plant extract manufacturer in Southwest China with small- and medium-sized stainless steel essential oil extraction tanks and matching steam generators, along with custom-designed components such as an enlarged condenser, quick-opening residue discharge system, and condensate recovery system. The essential oil recovery rate exceeded 90%, and the entire production line achieved significant energy savings. Engineer Li provided technical support throughout the project.

Essential Oil Extraction Project at a Plant Extract Company in Southwest China—Engineer Li’s Notes: From Waste Liquid to Essential Oil—All It Takes Is a Custom-Built Piece of Equipment
I. Project Background
A plant extract manufacturer in southwest China (the name and specific location have been withheld to protect privacy) generates large amounts of plant extract residue during production, which is rich in volatile essential oils. Previously, this residue was treated as wastewater, a process that was costly and wasteful of resources. The client hopes to recover high-value components using essential oil extraction equipment, thereby “turning waste into treasure.”
II. Equipment Configuration and Technical Points
| Equipment | Key Specifications | Customization Options |
|---|---|---|
| Essential Oil Extraction Tank | Small to medium size, 316L stainless steel, mirror-polished interior | Condenser Heat Exchange Area Increased 30%-50% |
| Steam Generator | Meet the steam demand for the extraction tank | Add a condensate recovery loop to preheat the makeup water |
| Drying Oven | On hold, but with a hot-air drying port reserved | Add a switching valve—a low-cost option |
| Slag Removal System | Large-Bore Quick-Opening Butterfly Valve | Larger than the standard configuration, designed to accommodate fiber residue |
| Safety Accessories | Anti-static grounding, safety valves, pressure gauges | All configured for explosion-proof zones |
III. Engineer Li’s Feedback (Real-Life Service Details)
A Small Trial Run: The customer sent in a sample of residual liquid, the lab determined the optimal parameters, and the process was scaled up successfully on the first try.
Condenser Enlargement: The recovery rate of low-boiling-point components has increased significantly, and the additional essential oil recovered over the course of a few months has more than covered the difference in equipment costs.
Quick-Open Discharge: The customer had initially been concerned about tank blockages, but the tank actually emptied quickly, saving a significant amount of tank-cleaning time compared to the standard design.
Condensate Recovery: Energy consumption across the entire production line has been significantly reduced, resulting in substantial annual savings on electricity bills.
IV. Operational Results and Customer Feedback
Essential oil yield: consistently at or above 90%
Processing Capacity: Meets customers' daily production needs
Annual Revenue: Approximately 500,000 yuan from essential oil sales and savings on wastewater treatment fees combined
Customer review: “Engineer Li’s team is based in Chongqing, which is close to us, so their service is fast. Plus, they conduct pilot tests first and let the data speak for itself—they’re more reliable than people who just try to sell equipment.”
