Leaf Filters are ideal for Solid-Liquid Separation & work on principle of Precoating & pressure. Pre coating is done with the help of suitable filter aid about 0.5 to 1% ( Bleaching earth , supercel, Hyflo, super flo etc.) mixed with the liquid to be filtered. Unfiltered liquid is pumped into the filter vessel. Initially the filter aid starts forming a precoat layer on both sides of the filter leaves, until then cloudy material comes out of the Filter. Once the layer is formed , Pressure starts developing, restricting the impurities. Clear liquid flows from both sides into the leaves ( filter elements), flows along the tubular channel & gets discharged from Bottom of the leaf. All the leaves are mounted on a common manifold. The leaves start getting choked on both the sides by impurities forming cake, which is in wet form. Once the leaves get chocked completely, the pressure rises to 3-4 Kgcm² & the output flow almost stops.

The process of EDIBLE OIL REFINING in general comprises of Degumming, Neutralization, Bleaching and Deodorization and Winterisation. Chemical refining is the traditional method whereby the free fatty acid of the crude oils are neutralized with Caustic Soda. The resultant Sodium Soaps are removed by Batch Settling or by means of Centrifugal Separators. The neutral oils are subsequently bleached and deodorized. This method can be used for reliably refining virtually all crude oils, including oils of low quality, with the exception of Castor Oil.

Agitated Nutsche Filter is a closed vessel designed to separate solid and liquid by filtration under pressure or vacuum. The closed system ensures odourless contamination free and non-polluting working conditions maintaining product purity and hygiene. Agitated Nutsche Filters are extensively used in Chemical, Herbal,pharma,agro chemical and the food industry.The Agitated Nutsche Filter consists of a cylindrical shell with top dished and welded flat bottom. The base plate is stiffened by supports welded under the base plate. The base plate is having arrangement of bolting bar to hold the filter cloth. Suitable support mesh is provided under filter cloth to facilitate the flow of filtrate. Suitable nozzles are provided including Manhole and Side discharge nozzle. Solid bar is used for Agitator shaft and solid plate for blades made in specially “S” curved to take high torque generated during solid discharge and re-slurring operation.

The Pressure Leaf Filter is a MSSS Vertical Vessel with Filter Leaves inside. The leaves are mounted vertically on a common manifold pipe, through which the filtered liquid flows out. On the top, the leaves are held by a vibrating shaft . A mechanical vibrator driven by electric motorpneumatic vibrator is provided for vibrating the leaf shaft for cake discharge. Jacket for hot filtration can be offered if desired Over flow, ventsteamair charging, pressure gauge & safety valve are provided on the top.

The widespread use of the three oil modification processes - hydrogenation, interesterification and fractionation - extended the range of applications of the triglyceride oils. These processes principally serve the purpose of modifying the melting properties of oils and fats in order to improve their functional properties in specific applications, but the processes are also used to improve the stability of the oils and fats thus processed.Triglycerides with a high degree of unsaturation, indicated by a high iodine value, have a lower melting point than those containing more saturated fatty acids. If oil is cooled to a certain temperature, the high melting triglyceride (Stearin) will crystallize while the low melting ones will remain fluid. The stearin can then be separated from oil (Olein) by different methods and the fatoil is thus divided into two fractions: Stearin with a high melting point and olein with a low cloud and melting points. through batch crystallization of oil without using additives by controlled cooling and subsequent continuous filtration.

Dewaxing (also called winterization) of sunflower oil is essential when the oil is to be used as salad oil. The presence of wax makes the oil appear cloudy at room temperature. The oil normally becomes cloudy in 5–6h but with proper dewaxing the oil remains clear after 24h of storage at 0˚C.Separation of waxes, esters of long chain fatty acids and long chain primary alcohols present in mainly sunflower and maize oil.
