Rosemary Extraction Equipment Manufacture

The solvent extraction equipment mainly consists of extraction tank, multi-stage countercurrent extraction unit, filter, vacuum evaporator, separation equipment, purification equipment,solvent recovery tower, drying equipment.

The core advantages of solvent extraction in rosemary extraction lie in its wide extraction range, high efficiency, and adaptability to industrial production: it can simultaneously dissolve both lipid-soluble (carnosic acid) and water-soluble (rosmarinic acid) active ingredients, achieving an extraction rate 30%-50% higher than steam distillation and fully retaining effective substances. The process is flexible and adjustable, allowing for targeted enrichment of target components through the selection of different solvents such as ethanol and ethyl acetate, thus adapting to the development of multiple types of products. It supports multi-stage countercurrent extraction, achieving high solvent utilization and low loss. Coupled with a vacuum low-temperature concentration system, it can avoid the degradation of heat-sensitive components and ensure product quality. The equipment has strong adaptability, allowing deployment from small-scale test devices to large-scale production lines. The investment and operation and maintenance costs are moderate, meeting the mass production needs of small and medium-sized enterprises. Furthermore, the solvent recovery system complies with environmental protection requirements.
