PURPOSE:To meter and deliver a cooking food material at a uniform delivery rate, without deteriorating the quality of the material, by introducing a cooking food material into a specific metering apparatus while keeping the pressure at the outlet port of a screw apparatus at a constant level and continuously extruding the material by the aid of a control board. CONSTITUTION:A cooking food material 1 in a hopper 2 is transferred with a screw 4 in a cylinder 3. The rotation of the screw 4 is controlled to keep the pressure near the inlet 7 at a constant level by detecting the pressure of the material with a pressure sensor 21 attached to the inner wall of an inlet 7 of a housing 6 of a metering apparatus placed at the extrusion nozzle and transmitting the detected pressure signal to a control board 20 composed of an input unit, storage unit, comparing unit and operation unit. The material 1 is introduced into a cylinder 8 constructing a metering apparatus and rotating with a motor 5 and a driving shaft 10. The cylinder is furnished with a flat plate 12 which is removably inserted into a slit grooved on a generant via a cam 13 along the direction of outer circumference. The rotation of the motors 5, 15 are controlled via the control board 20 and the cylinder 8 is rotated by the motor 15 in the direction of the arrow (a). The material is passed through a closed metering chamber 16 between the positions A and B and is extruded through an extrusion nozzle 19 at a constant flow rate. |
