In groundnut oil extraction, salt is usually added to coagulate the protein and enhance oil separation. A large rotating pestle in a fixed mortar system can be powered by motor,
Green Vegetable Oil Processing | ScienceDirect
Concerns related to green processing and organic feeds might become an incentive for equipment manufacturers to design screw presses for higher capacities, pressing to lower residual oils and consuming less horsepower. Significant work is already being done in these areas. Today's higher capacity full-presses operate at around 130 MT/d
Extraction of Vegetable Oils from Agricultural Materials:
This paper provides a comprehensive review of vegetable oil extraction, both from the standpoint of research
Oil Fractionation - an overview | ScienceDirect Topics
Fractionation is a separation process, which involves dividing and collecting bio-oils or bio-vapors under different conditions to obtain products with varying compositions. Several fractionation concepts have been proven, including distillation, extraction, and separation by solubility properties [86].
Dewaxing Process Oil Refinery
Description For Dewaxing ProcessSteps For Dewaxing of Vegetable OilsTrivia Crude oil is refined and bleached to low phosphorus (<1ppm) and low moisture content (<0.1%).The oil is heated to 55˚C to make sure the oil is fully liquid. This is already achieved in the Cooler Vessel while reducing the deodorization temperature.The oil is then slowly cooled 10–15˚C. Chiller helps for the same.

Dewaxing Process, Oil Dewaxing Process, Sunflower Oil
The reason for hazy appearance is due to the precipitation of dissolved waxes. The presence of wax makes the oil appear cloudy at room temperature. The oil normally becomes cloudy in 5? h but with proper dewaxing the oil remains clear after 24h of storage at 0藲C. Dewaxing is carried out by chilling the oil up to 10-15 C into the crystallizers.
Edible Oil De-waxing & Winterization Kumar Metal Industries
The dewaxing or winterization process involves the cooling of oil to crystallize high melting compounds followed by filtration or centrifugation to separate crystallized mass from oils.

The main purpose of dewaxing is to remove hydrocarbons that solidify readily (i.e., wax) for making lubricating oil base stock with low pour points (-9 to 14 F). Figure 5.11. Feedstock for dewaxing and hydrocarbon composition of the feed and the products. In addition to low pour points, other important properties of lube oil base stocks include:

HVI ensures that the lube oil functions well at both cold start and at high temperatures generated by the engines. Thermal Stability High thermal stability (or small degree of thermal degradation at high temperatures) is
Oil Dewaxing Winterization,Fractionation - Oil Mill Plant
Oil dewaxing and fractionation are based on the same principle, but they have different purposes. Dewaxing is by removing wax content to improve the palatability and quality of the oil. While fractionation is by using the differences of glycerol melting point and solubility to obtain solid fats & liquid oils from raw material.
