Example Embodiment

[0016] Example 1

[0017] Such as figure 1 Shown as an extruder, it includes a motor 1, a transmission system 2, a feed port 3, an expansion cavity 4, and a discharging device. The feed port 3 is arranged at the front end of the expansion cavity 4, and the discharging device is arranged in the expansion cavity. At the rear end of 4, the discharging device includes a discharging cavity 13 and a discharging template 12 arranged at the end of the discharging cavity. An extrusion screw 16 is provided in the expansion cavity 4, and the transmission system 2 is in transmission connection with the extrusion screw 16. , There is also a discharge control valve between the discharging device and the puffing chamber 4. The discharging control valve includes a valve body 9. The valve body 9 is provided with a valve chamber 5 penetrating the valve body 9 laterally. The back end of the cavity 4 is connected, and the other side of the valve cavity 5 is connected to the discharge cavity 13; the ...

[0022] Example 2

[0023] Such as Figure 5 As shown, there are two discharging control valves. A three-way 17 is provided between the rear end of the expansion chamber 4 and the discharging control valve. The other two channels of the three-way 17 are connected to the discharging control valve 15A, The discharge chamber 13 of the second discharge control valve 15B is connected.

[0024] When working, the discharge control valve 15A can be in the closed state, and the discharge control valve 15B can be in the flow-through state. The material enters and is extruded from the discharging template 12 of the discharging control valve 15B in the flow-through state. At this time, the discharging device corresponding to the closed discharging control valve 15A can be overhauled and the discharging template 12 can be replaced; there is no need to shut down for maintenance, which ensures the normal operation of the extruder and realizes the efficiency of the extruder improve. It is also ...

Abstract

The invention discloses an extruder in the field of grain feed machinery, which comprises a transmission system, a feed inlet, an extrusion cavity and a discharge device. The feed inlet is formed at the front end of the extrusion cavity; the discharge device is arranged at the rear end of the extrusion cavity; a discharging control valve is also arranged between the discharge device and the extrusion cavity; the discharging control valve comprises a valve body; and the valve body is provided with a valve cavity which transversely passes through the valve body. One side of the valve cavity is connected with the rear end of the extrusion cavity, and the other side of the valve cavity is connected with a discharging cavity in the discharge device. A spool mounting hole which longitudinally passes through the valve body is also formed on the valve body, and is intersected with the valve cavity; a lifting spool is arranged inside the spool mounting hole in a matching mode; the middle of the spool is provided with a transverse runner; the lower part of the spool is provided with a downward discharge channel; a side hole of which the opening faces one side of the extrusion cavity is formed on the upper part of the discharge channel; and a lifting regulating device is connected to the upper part of the spool. The extruder can regulate the pressure in the extrusion cavity, flow away materials by a bypass, and guarantee the balanced quality of extrusion processing.

Description

technical field [0001] The invention relates to an extruding and expanding equipment in the field of food and feed machinery, and is especially suitable for extruding and expanding machines that need to frequently adjust the extruding pressure. Background technique [0002] Extrusion technology has long been widely used in the field of food and feed processing. In the prior art, in order to obtain extruded puffed products of various sizes and densities with high gelatinization degree, the material is firstly passed through a conditioner using water and steam for conditioning, and the material is mixed with water, water and steam in the conditioner. The steam is fully contacted and penetrated, and after a certain period of time, the material is pre-gelatinized to a certain extent, and the pre-gelatinized material enters the screw extruder for extrusion. Existing screw extruders include single-screw extruders, twin-screw extruders and multi-screw extruders. The core part of ...
