FIELD: food industry.SUBSTANCE: inventions group relates to a method and a device for production of puree-like cooked food products of lump raw materials and a blades system for food products milling in the said device. The method consists in preliminary milling of lump raw materials in the preliminary milling unit (1), preliminarily milled raw materials cooking in the cooking installation (6) designed with the possibility of continuous loading, final treatment of the cooked product in the final treatment unit (12). Before cooking, lump raw materials are cut into small pieces in the preliminary milling unit (1) by means of the blades system (2) so that lump raw materials become a pumpable mass. The device contains a preliminary milling unit (1), a preliminary milled raw material transporting pump (8), a cooking installation (6) designed with the possibility of continuous loading and a final treatment unit (12) for the food product final treatment. The preliminary milling unit (1) has exclusively the first rotation blades system (2) for lump raw materials cutting to produce a pumpable mass. The blades system contains in the preliminary milling unit (1) a coarse milling device (56) and at least two cutting units (60, 61), each of them including a rotor (62, 63) and a stator (64, 65).EFFECT: during cooked puree-like food products manufacture raw materials compression is prevented thus to separate a solid phase from a liquid one.17 cl, 10 dwgГруппа изобретений относится к способу и устройству для изготовления пюреобразных, вареных продуктов питания из кускового сырья и системе ножей для измельчения продуктов питания в вышеуказанном устройстве.
