BRIEF OVERVIEW
Refined Glycerine, also identified as glycerol or glycerin, stands as a fundamental sugar alcohol with three hydroxyl groups, bestowing water solubility and hygroscopic attributes. This transparent, colorless, and odorless liquid, characterized by a high boiling point and viscosity, showcases inherent sweetness and minimal toxicity. With a density of 1.26 g/cm³, it originates from petrochemical feedstock and caters to a variety of sectors, including food, medicine, cosmetics, personal care, and biodiesel production.
MANUFACTURING PROCESS
Threshing
Initial palm fruit treatment involves threshing to eliminate the primary stem and attached spikelets.
Sterilization
Steam application to palm fruits prevents hydrolysis and oxidation, facilitating the detachment of kernel, gum, and resin.
Digestion
Mechanically mixing and pounding sterilized fruits releases palm oil, facilitated by additional heat.
Pressing
Hydraulic pressure extraction is utilized to obtain palm oil from processed fruits.
Oil Clarification
Extracted oil undergoes purification, involving hot water addition for impurity removal and subsequent filtration.
Deacidification
Solvent extraction with methanol eliminates free fatty acids, crucial to preventing oil oxidation.
Transeferication/Saponification
Hydrolysis breaking down triglycerides into glycerol and fatty acids requires further refining for refined glycerine.
Glycerin Pre-treatment
Separation processes refine the mixture of glycerine and fatty acids through distillation.
Evaporation
Remaining methanol from the deacidification process is evaporated to produce fully refined glycerine.
