AI Technical Summary
Technical Problem
Among the existing tea oil extraction methods, tea bran has low oil utilization rate and high extraction cost, making it difficult to achieve large-scale and industrialized production.
Method used
Tea oil is extracted from tea seed cake using water extraction, impurity removal, and drying steps. This process includes crushing, water extraction, impurity removal, and vacuum drying. Membrane technology is used to remove impurities and concentrate the tea oil, avoiding the use of chemical reagents and preserving the components in the tea seed cake.
Benefits of technology
It improves the yield of tea oil, reduces production costs, and retains the original components of tea bran, making it easier to use later and reducing the need for solvent extraction.
