,Fully Automatic Ethanol Extraction Equipment
The industrial closed loop ethanol extraction equipment is a high-performance system designed for large-scale botanical extraction, including CBD oil, essential oils, and pharmaceutical-grade plant compounds. Using food-grade ethanol as a solvent, the system efficiently dissolves active compounds from biomass while maintaining high selectivity and stability. The closed-loop design ensures that ethanol is continuously recycled within the system, minimizing solvent loss and significantly reducing operational costs.
Compared with traditional open-loop or semi-manual extraction methods, this system provides a far more stable, efficient, and scalable solution. It is engineered for continuous industrial operation, making it suitable for manufacturers who need consistent output and high throughput. The system is widely adopted in North America and Europe due to its compliance-friendly design, safety features, and strong adaptability to regulated industries such as CBD, nutraceuticals, and pharmaceutical extraction.
Many extraction manufacturers struggle with inefficiencies in traditional ethanol extraction processes. Open systems often result in solvent evaporation, inconsistent batch quality, and high operational risks. In addition, manual operation leads to variations in extraction conditions, making it difficult to maintain consistent cannabinoid profiles or terpene retention.
Another major issue is the lack of integration between extraction, filtration, and solvent recovery systems. Without a unified process, manufacturers face increased labor costs, longer production cycles, and higher energy consumption. These challenges become even more critical when scaling production for international markets where regulatory compliance and batch consistency are required.
The closed-loop ethanol extraction system solves these challenges by integrating extraction, filtration, evaporation, and solvent recovery into a single continuous system. Ethanol is circulated in a fully sealed environment, significantly reducing solvent loss and improving operational safety.
Advanced temperature control ensures that extraction occurs under optimal conditions, preserving sensitive compounds such as cannabinoids and terpenes. The system also supports multi-stage filtration, which improves clarity and purity of the final extract. Integrated solvent recovery units allow ethanol to be reclaimed at recovery rates of up to 95% or higher, making the system highly cost-efficient.
PLC automation is available for full process control, allowing operators to manage temperature, flow rate, and extraction cycles with precision. This reduces human error, improves consistency, and ensures compliance with GMP and industrial production standards.

This ethanol extraction system is widely used in CBD oil production, herbal medicine manufacturing, nutraceutical processing, food-grade ingredient production, and cosmetic raw material extraction. It is particularly suitable for companies targeting regulated markets in Europe and North America, where solvent safety, traceability, and product consistency are critical requirements.
In CBD production, it is used for full-spectrum oils, broad-spectrum extracts, and distillate production. In pharmaceutical applications, it supports extraction of active plant compounds for further formulation. In food and beverage industries, it is used for natural flavoring agents, plant-based additives, and functional ingredients.
The process begins by loading prepared plant biomass into the extraction vessel. Food-grade ethanol is introduced into the system and circulated through the material, dissolving cannabinoids, terpenes, and other active compounds. The mixture is maintained under controlled temperature conditions to optimize extraction efficiency.
After extraction, the solution passes through filtration units that remove plant solids and impurities. The ethanol-containing extract is then transferred to the evaporation system, where ethanol is separated from the active compounds through controlled heating and vacuum processes. The recovered ethanol is condensed and returned to the system for reuse.
This continuous closed-loop process ensures minimal solvent waste, stable production output, and high-quality extracts with consistent chemical profiles.
When selecting an ethanol extraction system, manufacturers should consider production capacity, automation level, and solvent recovery efficiency. Smaller operations may choose 100L–200L systems for pilot or mid-scale production, while industrial manufacturers typically require 500L–2000L systems for continuous output.
Automation is a key factor for scalability. Fully automatic PLC systems are recommended for large-scale operations due to improved consistency and reduced labor costs. For companies targeting pharmaceutical or food-grade markets, stainless steel 316L construction and GMP-ready design are essential.
Solvent recovery efficiency is another critical factor. Systems with ≥95% recovery rate significantly reduce long-term operating costs and improve environmental sustainability.
