Rosehip Oil Extraction Procedure

Rosehip oil is increasingly popular in cosmetics industry due to its extraordinary benefits as a natural beauty product. It contains a lot of essential nutrients, including vitamins, essential fatty acids, therapeutic ingredients and more. Because of its clarifying and rejuvenating beauty effects, rosehip oil has amazingly magical natural healing and beauty functions.

There are many methods to extract rosehip oil, including Cold Pressing, Chemical Extraction, Supercritical Extraction and Sub-critical Solvent Extraction. The quality of rosehip oil is largely decided by its processing procedure, so choose the right method procedure is a key step for rosehip oil extraction.

Analyzing of Different Rosehip Oil Extraction Procedures

Detailed Procedure of Rosehip Oil Extraction

Rosehip Oil Extraction Machinery

The Sub-critical Solvent Extraction Technology, invented by our Chief Engineer Dr. Qi Kun, is leading solvent extraction procedure for rosehip oil extraction. It makes up the deficiency of rosehip oil production technically. This procedure mainly adopts propane and butane as the solvents since the two solvents is in gas state at normal temperature and pressure, has quality of low boiling point and volatility. Our rosehip oil extraction method makes fully use of the solvents characteristics to extract and separate rosehip oil from rosehip haw and rosehip seeds. Below is the detailed introduction of our rosehip oil extraction procedures.

Pre-treatment Procedure of Rosehip Seeds

Rosehip Seeds → Conveying → Cleaning → Crushing → Deironizating → Flaking → Drying → Extraction Workshop
Procedure description：the raw material is cleaning with vibration screening to remove peel impurities, stones and other impurities. Then, cleaned raw material is transported to dehulling machine and flaker. The thickness of rosehip seed flake is about 0.3mm, and the moisture is about 8%. This is whole procedure of rosehip seed pretreatment. All processed rosehip seed flake is transported to next sector - Low Temperature Extraction

Low Temperature Sub-critical Solvent Extraction Procedure for Rosehip oil

The main solvent is propane and butane and both of their boiling point is below 0 °C. The extraction procedure is under certain pressure (0.1 -0.6 MPa) and room temperature. The solvent within extracted crude oil and meal will be desolventized under low temperature and vacuum condition. And solvent is processed within this system for recycling. So our patented sub-critical low temperature extraction procedure is the most suitable method for rosehip oil since it preserve the active ingredients of the original rosehip seed, this is to say, extracted rosehip oil has the same condition with the rosehip seeds. So all its active component, protein are completely protected, which provides good condition for further development and process of rosehip oil.
