FIELD: food industry.

SUBSTANCE: device for oil extraction from oil-containing vegetable raw material, comprising a housing with hoppers for loading raw material and unloading meal, a conveyor horizontally mounted in the housing, with a mesh endless belt resting with its working and idle branches on roller bearings mounted rotatably, sprinklers for the pure solvent and miscella supply, placed above the working branch, as well as miscella collectors and pumps for recycling the micella in the sprinklers, located below the upper working branch of the mesh belt; the novelty is in the fact that the working conveyor branch is designed as a mesh endless belt cascade by means of its bending around a series of roller bearing pairs alternating according to the conveyor working branch length, placed one under another with displacement of the lower roller bearing towards the upper one in the opposite direction from the conveyor motion direction, with forming the idling area of the conveyor working branch. Under the idling area of the mesh endless belt of the conveyor working branch, formed between a pair of roller bearings, a device for cleaning the mesh endless belt in the form of a brush is arranged with the possibility of rotation.

EFFECT: invention allows to increase the extraction efficiency, to increase the oil yield and to reduce the oil content of the meal.
