lnteresteri?cation process is random chemical process is the most general applied. The best known catalysts are alkali metals such as sodium, potassium and their alloys and alkoxides such as sodium methylate or sodium ethoxide. Fatty acid neutralization and drying is therefore necessary prior to the addition ofthe phosphoric acid.  

Fractionation is the process where the crystallization of saturated triglyceride takes place in a mechanical equipment called the crystallizer. Crystallized oil is further passed through a filter where separation of solid and liquid phase takes place. Solid phase remains in the chamber. Liquid phase comes out through the taps and is collected in the storage tank. Entire process takes place in several steps which including: Oil heating, oil charging, and crystallization, filtration, squeezing and cleaning of filter.    

ABSTRACT Mectech provides Connuous Saponificaon Plants ranging in capacity starng from 1 TPH. Soap Noodles are manufactured from the Fay Acids of oil and fats derived from vegetable oil. Soap Noodles have a wide applicaon in the manufacture of Toilet Soaps, Laundry Soaps and Bathing Bars.   MECTECH ADVANTAGE Plant is Fully Automac. This is the only Connuous Saponificaon plant which gives precise control over free alkali content in Soap Noodle. No external heang of Neat Soap is required which in turn minimizes the ulity consumpon.  

Mectech employs the following milling techniques for seed preparation: Roller Mill: The seeds are crushed into tiny particles in these mills. The process involves preparation of oil seeds prior to direct solvent extraction. Flaking Mill: Oil seeds need to be flaked to ensure profitable extraction. This process disintegrates the cellular structure of seeds. The equipment is fitted with smooth rolls, suitable for flaking oil seeds or cakes prior to solvent extraction.  

Rice bran oil is normally refined by physical method to keep the Oryzanol in the refined oil. In chemical process Oryzanol get destroyed by alkali. For the physical refining of Rice bran oil following processing steps takes place. Degumming Pre Bleaching Dewaxing Winterization (Optional) Post Bleaching Deodorization  

Acid oil is produced by spling of vegetable oil soap stock with sulphuric acid or hydrochloric acid. Spling process can be performed either in batch or in connuous process, but considering the producon cost and quality of acid oil, connuous process is more economical then the batch process.  

Spling is the process through which the triglyceride hydrolysis is carried out, breaking up the molecules to obtain fay acid and glycerine. The mechanism of this reacon goes through three steps – the triglyceride is successively transformed into diglyceride, monoglyceride and glycerine, liberang fay acid in each step. Mectech has built several plants for thermal pressure spling of fats and oils with water into fay acid and glycerine. It is a simple economical process and does not pollute the environment. Mectech provides Fat Spling Plant ranging in capacity from 30 – 1000 TPD.    

The Crude Glycerin obtained from the process of Oils / Fats Splitting ( Sweet Water Crude ) OR Saponification ( Spent Lye Crude ) OR Trans esterification ( Biodiesel Crude ) can be converted to Refined Glycerin of different grades ( Chemically Pure , Industrial or Pharma ) by using the following process in sequence . Drying cum Dearation Distillation & Deodorization Bleaching Salt Decanter or Agitated / Wipe Film Evaporator ( Optional – To improve yield & reduce waste generation )  

Glycerine is a ubiquitous substance that is widely found in nature and has a broad range of uses ranging from Cosmetics to Food Products. Mectech has long experience in the Oils & Fats and Oleo—Chemical industry sectors which has long been associated with the production of Glycerol as a by-product. Plants executed by Mectech produce Glycerol by the following means — the Transesterification of Methyl Esters, from Fats Splitting and by Saponification which is used to produce soap. The Glycerine / Sweet Water purification and evaporation allows maximum recovery and pre-treatment before evaporation to produce Crude Glycerine. The pre-treated sweet water is concentrated in Triple Effect or Quadruple Effect Evaporation systems under vacuum. The use of multiple effects reduces the requirement of steam.  

Hydrogenation is the process to change the physical characteristics of natural fats and oils. Hydrogenation of vegetable oils/fatty acids involves the addition of hydrogen, in the presence of a Nickel catalyst, to the carbon-carbon double bonds present in the fatty acid chains. Salient features High degree of Automization to control flow, temperature and pressure in Autoclave ensures selective hydrogenation and excellent quality product. 100% reproducibility of product is ensured. Almost zero steam consumption for heating. Steam is needed only once for the first charge of oil while starting the plant operation. This is achieved with the most efficient design of oil to oil Heat Exchanger. Practically maintenance free due to low speed agitation system in Autoclave. Low power and catalyst consumption

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.
