dewaxing plant
Dewaxing - Dewaxing of oil is a process of eliminating higher melting point constituents like waxes or triglycerides from oil by gradually cooling vegetable oils and separating saturated glycerides from the oil. Normally Dewaxing process carried out at higher temperature (18-20 °C) to avoid the crystallization of saturated triglycerides & amalgamation of waxes & saturated triglycerides. Winterization- Waxes & Saturated triglycerides which are fairly visible at low temperature are removed in this process to keep the appearance oil clean transform Degummed, Bleached & Dewaxed oil is cooled and filtered to achieve the quality.

Solvent Extraction Plant
Mectech's belt-type horizontal extractor: the extraction plant comprises of extraction de-solventizing toaster, a distillation system and a solvent recovery system. The extractor enables removal of the solvent from the meal, toasts the meal to maintain inherent nutrition, and stabilizes its moisture as well as temperature. This equipment is efficiently designed to achieve the best of performance in terms of quality of oil, quality of doc, consumption of utilities and hexane loss. solvent extraction is a multi-level process used to extract oil from the seeds by use of a solvent. Post milling, the meal is ready, which means that the seed has been improved to a form which enhances its surface area for solvent absorption. This meal is transferred to the extractor, where it comes in contact with hexane (solvent). The oil meal and miscella are the outputs which are further processed and distilled for optimum extraction of oil and solvent removal.

Pre-treatment & Bleaching Deacidification/Deodorization Pre-treatment & Bleaching The aim of Pre-treatment & Bleaching is to remove minor constituents namely phospholipids, heavy metals and other oxidative components prior to Deacidification/ Deodorization. Specially designed Pre-treatment & Continuous Bleaching Plant by MECTECH is cost effective and ensures perfect results. Equipment for Pretreatment & Refining designed by MECTECH ensures deacidification by distillation of free fatty acids combined with partial or complete deodorization. Mectech is one of the top Oil Deodorization Systems manufacturers & Deodorizing Plants suppliers in India and abroad. Deacitification / Deodorization Salient features: The Deaeration and Pre-heating is gradual and methodical so that all the oil comes in contact with this sparging system at the free surface exposed to vacuum. An additional top heating tray is provided in the Deacidifier/Deodorizer to compensate the unavoidable oil cooling of about 8'C due to evaporation of fatty acids. Perfect deodorization is accomplished by providing large free surfacing area contact between oil and stripping steam at an absolute pressure of 2 m bar.

GLYCEROLYSIS PLANT
It is well known that Oil is ester of Glycerol and fatty acids, which can be decomposed in to their original constituent (Fatty acid and glycerol) or synthesized in to Triglycerides by Fatty acids and glycerol. Abstract Glycerolysis reaction is reverse of Hydrolysis process. It is carried out by reacting fatty acids with glycerol. In addition to esters, water is also a product of Glycerolysis. The reaction is reversible and proceeds to completion only if water is removed from the medium. The equilibrium between the forward reaction (Glycerolysis) and the reverse reaction (Hydrolysis) is controlled by water content of the reaction mixture. In the presence of excess water, hydrolysis predominates, whereas under water eliminating conditions Glycerolysis is favored. Mectech Advantage Mectech supplies PLC automated continuous Esterification plants to convert fatty acids into oil with 0.1% final FFA.

CONTINUOUS DEODORIZATION
1. Continuous Deodorizer for High FFA Oils Vegetable oil is heated to the desired temperature in a multi-compartment Vacuum Heater with counter current flow of vegetable oil and heating medium i.e. High Pressure Steam or Thermic Fluid. Pre-heating is gradual and methodical so that all of the oil comes in contact with this sparging system at the free surface exposed to vacuum. Packed Column with packings of large surface area is provided on the top of Deodorizer. This ensures reduction of Free Fatty Acids to the desired level. An additional top heating tray is provided below the Packed Column to compensate for the unavoidable loss of heat due to evaporation of Fatty Acids.

Chemical Refinery Plant
the edible oil refining processes are degumming or gums conditioning/neutralization, bleaching and deodorization. the degumming and neutralization process removes phospholipids and fatty acids to improve its physical stability. The phospholipids can lead dark coloured oil. With this process, the fatty acids, pigments, and other particles are removed. the next step is bleaching, which is a process of selective removal of impurities and pigments by the physical and chemical interaction. The process removes colour pigments, dirt, trace metal, and phospholipids. the last step of vegetable oil refining is deodorization, which is a vacuum stripping process where a certain quantity of stripping steam is passes through hot oil at a very low pressure. It is mainly a physical process, but because it is carried out at a high temperature, some chemical effects may take place. enquiry
