Botanicals extraction plant is a facility that uses various methods to separate desirable chemical compounds from plant material, creating concentrated botanical extracts for use in products like food, beverages, herbal remedies, and cosmetics.
High-quality oils can be obtained by performing production at low temperatures using cold press method. It has an environmentally friendly use with no solvents. The soybean, sunflower, rapeseed, corn, grapeseed, hemp, flaxseed, rice bran, olive and pumpkin oils were obtained by it’s method.
The cold pressed oils can add to food as natural antioxidative additives due to phytochemicals and as fatty acid supplements due due to invaluabile double bond fatty acid.
A distinction is made between various extraction processes, indicating first the aggregate state of the substance to be extracted and then that of the solvent. Different industries use various solvent extraction techniques depending on the nature of the compound being extracted and the desired purity level.
Technology utilizes the special properties of the subcritical and supercritical fluids. Raw material put into the extraction tank, soaked by fluid. Extract out ingredients by using their similar physical properties. Control certain material / liquid ratio, extraction temperature, time, and pressure. Sometimes supported by extraction agent and entrainer or with the aid of stirring and ultrasonic to finish the extraction process.
The extracted mixture passes through solid-liquid or liquid-liquid separation and enters the evaporation system. Under the action of the compressor and vacuum pump, the solvent is converted from a liquid state to a gas state. The left ingredient is the wanted extracts.
