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.

Products Details

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 shelling 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.After starting, the shells of peanuts are shelled by the rolling force between the rotating rasp bar and the fixed intaglio, and then shells and kernels fall through the grid mesh down to the air duct, and the fan blows shells out. The kernels and the unshelled small peanuts fall into the gravity separator. The separated kernels are sent upward to the outlet and the separated unshelled small peanuts are sent downwards to the elevator, and the elevator sends the unshelled peanut to the fine grid mesh to be shelled again until the whole batch of peanuts are all shelled.
