Oil Seeds Pretreatment: Groundnut Shelling Machine
Oil-bearing materials with shells such as groundnuts, sunflower seeds, cotton seed, and teaseeds, should be conveyed to the seed dehuller to be shelled and separated from their outer husk prior to the oil extraction process, the shells and kernels should be pressed separately. Hulls will reduce the total oil yield by absorbing or retaining oil in the pressed oil cakes. What’s more, wax and color compounds present in the hulls end up in the extracted oil, which are not desirable in edible oils and need to be removed during the refining process. Dehulling can also be called shelling or decorticating. The dehulling process is necessary and has got a series advantages, it increases oil production efficiency, capacity of the extraction equipment and reduces wear in the expeller, reduces fiber and increases protein content of the meal.

Oil Seeds Pretreatment Processing – Oil Seeds Disc Huller
After cleaning, oilseeds such as sunflower seeds are conveyed to the seed dehulling equipment to separate the kernels. The purpose of oil seeds shelling and peeling is to improve the oil rate and the quality of the extracted crude oil, improve the protein content of the oil cake and reduce the cellulose content, improve the use of oil cake value, reduce the wear and tear on the equipment, increase the effective production of equipment, facilitate the follow-up of the process and the comprehensive utilization of leather shell. The current oil seeds that need to be peeled are soybeans, peanuts, rapeseed, sesame seeds and so on.

Oil Seeds Pretreatment Processing- Small Peanut Sheller
Peanut or groundnut is one of the important oil crops in the world, groundnut kernel is often used to make cooking oil. Peanut huller is used to shell peanuts. It can shell peanut completely, separate shells and kernels with high-efficiency and almost without damage to the kernel. The sheeling rate can be ≥95%, the breaking rate is ≤5%. While peanut kernels are used for food or the raw material for oil mill, the shell could be used to make wood pellets or charcoal briquettes for fuel.

Oil Seeds Pretreatment Processing: Cleaning
The oilseed in the harvest, in the process of transportation and storage will be mixed with some impurities, so the oilseed import production workshop after the need for further clean-up, the impurity content dropped to within the scope of technical requirements, to ensure that the process effect of oil production and product quality.

Oil Seeds Pretreatment Processing-Destoning
Oil seeds need to be cleaned to remove plant stems, mud and sand, stones and metals, leaves and foreign material before being extracted. Oil seeds without careful selecting will speed up the wearings of the accessories, and can even lead to damage of the machine. Foreign materials are typically separated out by a vibrating sieve, however, some oilseeds such as peanuts may contain stones which are similar in size to the seeds. Hence, they cannot be separated by screening. Seeds need to be separated from stones by destoner. Magnetic devices remove metal contaminants from oilseeds, and hullers are used to de-hull of oilseed shells like cottonseed and peanuts, but also in crushing oilseeds such as soybeans.
