Embodiment Construction

[0015] The semi-cooked twin-screw extruder includes a machine base 1, a gear box 2, and an extrusion device 3. The extrusion device 3 is installed on the machine base 1. The extrusion device 3 has two screws 4 and an extrusion sleeve 5. The root screw 4 is arranged in the extruding sleeve 5, the gear box 2 has a main gear and two transmission gears, the two transmission gears are all engaged with the main gear, and the rear ends of the two screws 4 are respectively connected to the gear box through spline sleeves 2, the main gear can drive the two transmission gears to rotate in the same direction, and the main gear in the gearbox 2 is connected with the motor 7 arranged at the rear end of the support through a coupling 6. A feed inlet 8 is arranged on the upper rear end of the extruding sleeve 5, and five temperature-controlled water tanks 10 are arranged outside the extruded sleeve 5. The extruding device areas surrounded by the five temperature-controlled water tanks 10 cons...

Abstract

The invention provides a semi-cured food extrusion machine. The semi-cured food extrusion machine comprises an engine base (1), a gear box (2) and an extrusion device (3), wherein the extrusion device (3) comprises screw rods (4) and an extrusion sleeve (5); the screw rods (4) are connected with the gear box (2) in a matched manner; the screw rods (4) are mounted in the extrusion sleeve (5); and a feeding opening (8) is formed in the rear end of the extrusion sleeve (5). The semi-cured food extrusion machine is characterized in that the screw rods (4) are double screws; each screw rod (4) is connected with a corresponding gear in the gear box (2) through a spline housing; the extrusion sleeve (5) is externally provided with a plurality of temperature-controllable water tanks (10); different temperature regions are respectively formed by extrusion cavity regions surrounded by each temperature-controllable water tank (1); and each temperature-controllable water tank (10) is provided with a water inlet pipe (16) and a water outlet pipe (17). According to the semi-cured food extrusion machine disclosed by the invention, the temperature of each section of the extrusion cavity can be controlled, semi-cured extrusion machining of materials can be effectively realized and the loss of effective components can be reduced to the greatest extent; and the semi-cured food extrusion machine is particularly suitable for curing and extrusion machining of kudzu vine root starch.

Description

technical field [0001] The invention relates to a food processing machine, in particular to a food ripening extrusion machine. [0002] Background technique [0003] In the existing food processing technology, in order to obtain the ripened and extruded products, the material is first mixed with water to prepare a soft body, and then enters the screw extruder for ripening and extrusion, or directly uses steam to prepare the ripening, and then enters the screw extruder Mature extrusion molding. [0004] Existing screw extruders generally adopt a single-screw structure. For example, the Chinese invention patent application discloses an extruder (CN101057702A) for extruding high-starch raw materials, which includes a feeding chamber and an extrusion chamber. The feeding chamber is connected to the One end of the extrusion chamber, the discharge die is connected to the other end of the extrusion chamber, the front part of the feed chamber is provided with a feed port, the feed ...
