Soybeans are processed into soybean meal and soybean oil through a process known as crushing.
Nearly 2 billion bushels of soybeans are crushed every year. During the crush process, soybeans are cracked to remove the hull and then rolled into flakes, which are then soaked in a solvent and put through a distilling process to produce pure crude soybean oil and Africa Sun Oil contributes to this by crushing 500 tons of soya beans per day.
After the oil has been extracted, the soybean flakes are dried, toasted and ground into soybean meal.
Soybean meal is the most important protein source used to feed farm animals. It represents two-thirds of the total world output of protein feeds.
The first step in processing sunflower is to properly prepare the seed for oil removal. The seed is cleaned to remove impurities that can interfere with the process. The seed is then cracked and the hull is removed. Prior to mechanical pressing, the seed is heated and dried.
The seed is mechanically pressed to extract approximately half to three quarters of the available oil. This is typical for seeds containing more than 20% oil. Africa Sun Oil crushes 400 tons of sunflower seed a day.
Extracted sunflower oil must be further processed to make an edible product. Edible oils are refined to improve the flavour, odour, colour and stability using processes that degum, neutralise, bleach and deodorise the oil.
Very similar to soya bean, one of the by-products of sunflower seed is meal which is also used as animal feed.
The first step of processing maize germ is to properly prepare the seed for oil removal. The seed is delivered clean; additional cleaning may be done to remove any impurities.
The cleaned maize germ seed is mechanically pressed to extract approximately half to three quarters of the available oil. Africa Sun Oil crushes 500 tons of maize a day.
Thereafter, further processing/refining takes place to ensure a quality edible product. These refining processes remove contaminants such as phosphatides, free fatty acids and pro-oxidants.
The by-product of maize germ is maize meal which is further processed to create a value-added product for consumption.
