The invention relates to the extrusion of the material and is intended for use in processing agro-industries. Closest to the proposed method is a method of extrusion material, such as starch, by exposing the material rotating in the housing by a screw and pressing it through the extrusion head with channels (Patent RU №2236941, publ. 2004.09.27). The disadvantage is the high energy costs, a narrow range of technological capabilities. The invention solves the problem of reducing energy costs, expansion of production capabilities. To obtain this result, the proposed method on a material impact rotating in the housing by a screw, and the pressing is carried out through the extrusion head with channels, and compacting the material carried through the channels of the extrusion head, rigidly connected with the screw and movable relative to the housing in the axial and circumferential direction. Distinctive features of the proposed method are the following: compacting the material carried through the channels of the extrusion head, rigidly connected with the screw and movable relative to the housing in the axial and circumferential direction. Closest to the proposed device to realize the value of this method is the extruder, comprising a housing, screw extrusion head with channels (Patent RU №2294282, publ. 2007.02.27). The disadvantage of it is high energy costs, low reliability and durability of parts, the complexity of the design. The invention solves the problem of reducing energy costs, improving reliability and durability of the extruder, as well as to simplify the design by eliminating the need for the formulation of the thrust bearing Assembly of the screw. To obtain such technical result of the proposed extruder includes a housing, screw extrusion head with channels, and an extrusion head with channels made in the form of two concentrically arranged sleeves representing the rotational-translational couple, one of them equipped with TV and rigidly connected with the screw, and the other sleeve is rigidly connected to the housing, the diameter of the coupling sleeve with TV spigot attached to the housing, does not exceed the outer diameter of the auger more than 1.5 mm, in addition, an extrusion head contains the die plate made, for example, in the form of a tapered sleeve rigidly associated with the sleeve, provided with channels and installed coaxially with it, and extrusion head includes a mandrel or mandrels), tightly linked(s) with screw or Villeroy and set(s) coaxial channel (channel is) Spinneret. Distinctive features of the proposed extruder are the following features: die with channels made in the form of two concentrically arranged sleeves representing the rotational-translational couple, one of them equipped with TV and rigidly connected with the screw, and the other sleeve is rigidly connected to the housing, the diameter of the coupling sleeve with TV spigot attached to the housing, does not exceed the outer diameter of the auger more than 1.5 mm, in addition, an extrusion head contains the die plate made, for example, in the form of a tapered sleeve rigidly connected with the sleeve, provided with channels and installed coaxially with it, and the extrusion head includes a mandrel or mandrels), tightly linked(s) with screw or Villeroy and set(s) coaxial channel (or channels) Spinneret. The invention is illustrated by drawings, where figure 1 shows a section of the extruder with an extrusion head, figure 2 is a view along arrow a in figure 1, figure 3 is a section of the extruder with an extrusion head comprising a die plate and the mandrel, figure 4 - cross section In figure 3, figure 5 - section multi-Spinneret with mandrels. The extruder includes a housing 1, screw 2, the extrusion head with channels, and an extrusion head with channels made in the form of two concentrically arranged sleeves 3, 4, representing the x a reciprocating linear pair. One of them is equipped with 3 channels 5 or 6 and is rigidly connected with the screw 2, and the other sleeve 4 is rigidly connected to the housing 1. The diameter of the coupling sleeve 3 channels with the sleeve 4, fixed to the body, does not exceed the outer diameter of the screw 2 by more than 1.5 mm Extrusion head contains the die plate 7 made, for example, in the form of a tapered sleeve channel, rigidly connected with the sleeve 3 with channels 6 and installed coaxially with it. Extrusion head includes a mandrel 8 (or mandrels 9)rigidly connected(s) with screw 2 or Villeroy 7 and set(s) coaxial channel 10 (or channels 11) of the die 7 (see figure 3 and figure 5). The operation of the extruder is as follows. The material enters between the body 1 and the screw 2. At the same time he is exposed to heat, shear and pressure. At the outlet of the auger creates the pressure required for extrusion of the material through the channels 5. The process of extrusion material through the channels 5. In the result of the excess pressure forces acting on the screw 2 from an extrudable material, under pressure, balanced efforts applied to the sleeve 3 with the channels 5. Freedom of translational movement of the sleeve 3 with the channels relative to the sleeve 4, is rigidly connected to the housing of the extruder, allows you to balance the axial load acting on the screw, take the external forces in the internal efforts acting on the screw 2. In this case, the axial forces acting on the bearing unit of the screw 2, is practically zero. This reduces the energy consumption per unit of production, increases the durability and reliability of the extruder. This embodiment of the extruder eliminates the need for the formulation of the thrust bearing Assembly that simplifies the design and allows the screw to secure not a console, but on two pillars. This consolidation reduces the mutual wear of the ridges of the screw 2 and the housing 1 of the extruder at the end of the screw 2. Application in the extrusion head of the extrusion nozzle 7 and the mandrel 8 (or more mandrels 9) allows you to expand the range of product from the solid product to the hollow sections of different cross-section configuration. Technical solutions tested on laboratory experimental extruder. Experimental extruder included a housing with a screw diameter of 45 mm, bushing with twelve channels with a diameter of 5 mm and a length along the axis 20 mm length of the auger and its diameter is equal to 17, the angle of the cutting flange 17° (C), the cutting depth of 10 mm, the extrusion Pressure was changed in the range of 20÷70 atmospheres by setting screw speed. When used pressure extrusion axial force from the screw on the bearing unit according to the scheme of the prototype should be 3180÷11000 N. Indirect assessment to move freely mustache is set out in the axial direction relative to the housing of the auger showed what is the axial force in the proposed extruder is missing. Auger, mounted on two supports, rotates without beats, and this means that the mutual wear of the housing and crests of the screw is missing. 1.
