 Method of cooking of the food stuff by extrusion / 2293024
The invention is pertaining to the method of cooking of the foodstuff by extrusion. The method provides for reprocessing of the first food stuff having the density from 75 up to 130 g/l in the first section of the extruder, then they reprocess the second food stuff having the density from 75 up to 130 g/l in the second section of then extruder and extrude these two food stuffs through one common or two separate outlet holes. The first and second food stuffs are reprocessed in the opposite directions and as the result of it the food stuffs are moving towards to each other using rotation of one or two augers. The first section has essentially reverse spiral or the reverse spirals, as compared with the second section. According to the method the first and second food stuffs are combined before the extrusion and after that they are extruded through the common outlet hole.

FIELD: agriculture. SUBSTANCE: screw press comprises housing that receives screw and pressing unit made of cylindrical casing connected with the housing. The casing receives pressing head with conical and output cylindrical molding members for permitting rotation. The surface of the head is provided with arc-shaped passages which are mounted to define baffles between them. The cylindrical casing can be provided with longitudinal grooves arranged over periphery. EFFECT: improved quality. 1 cl, 2 dwg
The invention relates to agriculture, in particular to a device for the production of extruded feed in the form of briquettes. A device consisting of a body and the pressing unit. Inside is a single-thread screw with variable pitch. The pressing unit has associated with the housing casing having inlet cone and the output of the cylindrical part (A.S. EN 2118105 C1). The disadvantages of this device is the inability to deal with moisture forage accumulation generated in the pressing process gas in the space between the casing and Villeroy with holes, the pressure loss on the septum between the longitudinal grooves of the Spinneret. It is also known device consisting of a body and the pressing unit. The pressing unit includes associated with housing conical casing located in her conical plunger head. The pressure head is chopping knives, corrugated splitting surface, and forming in the form of arcuate slots. Conical casing made with holes for gatitude. At the junction of the body of the auger and casing pressure node at the top of the installed nozzle for input of mineral additives, and the bottom is made of gas and somatogamy channel (A.S. EN 2223863 C2). The disadvantages of this device are periodic clogging of feed is assay holes for gatitude, loss of pressure on the walls between the channels of the extrusion forming heads. Improving the quality of cooked briquettes and reduction of energy consumption is achieved by the fact that in a screw press comprising a housing placed inside a single-thread screw and the pressing unit as connected to the housing in a cylindrical casing in which is rotatably located plunger head with the lead-in bevel and output cylindrical molding parts made with located on the surface of the arcuate channels directed in the direction opposite to the rotation of the pressing head, with arcuate channels are made in the form of a semicircle and are arranged to form between them the walls in the form of ribs. In addition, the cylindrical casing is made located on the perimeter of longitudinal grooves for enhanced gatitude. 1 shows a screw press, General view; figure 2 is a section a-a in figure 1. Screw press consists of a housing 1 with a feed neck 2. Inside the housing 1 is located a single-thread screw 3 with a variable step turns, as well as the ribs 4, the anti-rotation promotes forage along the cavity of the press. In the front of the casing 1 by bolts 5 is mounted a cylindrical casing 6, which is on the perimeter made with longitudinal n the tears 7, for intensification of gatitude. Within the cylindrical casing 6 posted by plunger head 8, which includes the lead-in bevel and cylindrical output forming part of, the surface of the pressing head is made in the form of a semicircular arc-shaped channels 9, aimed in the opposite direction of rotation. Partitions between the channels of the extrusion is made in the form of ribs 10. The briquettes are cut by the blades 11, which are mounted on the cylindrical cover press 6. Screw press operates as follows. Forage mass goes to the feed neck 2, which is captured by a screw 3, which carries it along the cavity of the housing 1. To prevent proparacaine forage when sealing it by a screw 3 has ribs 4. Under the action of pressure of the efforts of the screw 3 forage mass is compressed, heated and partially plastification by step reduction of screw turns. Forage mass enters the conical lead-in portion of the plunger head 8, where its heat, compression and mechanical deformation, resulting in an excess of generated gas discharged through the longitudinal slots 7 for gatitude installed along the perimeter of the cylindrical casing 6. When forage mass under the action of rotation of the plunger head 8 slips in arcuate channels 9, made the shape of a semicircle and aimed in the direction the opposite rotation. The final formation of the briquettes is in arcuate channels 9 in the shape of a semicircle, the output cylindrical forming part of the plunger head 8. When the output from the pressure head of the finished briquettes are cut mounted on the cylindrical casing 6 knives 11. The proposed solution allows to improve the quality of cooked briquettes by increasing retention with minimal loss of their properties, to reduce pressure losses on the septum between the channels pressing and, as a consequence, the consumption of the process, to intensify gazoochistnoe. The economic effect is achieved by increasing the shelf life of the briquettes, the expansion of technological capabilities, expanding the range humidity initial forage mass from 14 to 38%reduction in energy intensity. 1. Screw press, comprising a housing placed inside a single-thread screw and the pressing unit as associated with the housing cylindrical casing in which is rotatably located plunger head with the lead-in bevel and output cylindrical molding parts made with located on the surface of the arcuate channels directed in the direction opposite to the rotation of the pressing head, characterized in that duroob asnie channels made in the shape of a semicircle and are arranged to form between them the walls in the form of ribs. 2. The press according to claim 1, wherein the cylindrical casing is made located on the perimeter of longitudinal grooves for enhanced gatitude.
