Embodiment Construction

[0017] refer to figure 1 , figure 2 , image 3 , Fig. 4, hollow shaft 7, outer ring 3, shaft chamber plug 4 are fixed together by pin 1. The inner ring 5 is looped on the middle section of the hollow shaft 7 , and the drum body 8 provided with a T-shaped handle 13 is fixedly mounted on the inner ring 5 by bolts 31 . The charged wire end of the electric heating rod 10 inserted in the inner cavity of the bottom 12 of the tube is contained in the transition mechanism formed by the hollow shaft 7, the outer ring 3, the inner ring 5, the shaft cavity plug 4, and the heat insulation sleeve 6. Because the electric heating rod 10 is mainly held by the heat insulating sleeve 6, the heat loss caused by heat conduction can be reduced, and the thermal efficiency of the whole machine can be improved. If necessary, a slip ring made of spring-like parts can be looped on the electric heating rod 10, so that the heat conduction between the rod 10 and the bottom 12 can be more effectively c...

Abstract

An internally heating puffing machine is composed of machine frame, drum, transfer mechanism, electrical heating rod, and drive mechanism. Said electrically heating rod and one end of drum are connected via transfer mechanism to the machine frame. Another end of drum is supported by a fork-type supporter. Said electrical heating rod is inserted in said drum which can rotate around its axle. Its advantages include compact structure, high heat efficiency near 100%, and no environmental pollution.

Description

technical field [0001] The invention relates to a food processing machine, especially an internal heating type puffing machine. Background technique [0002] Existing extruders (being commonly called as popcorn machine) are all external heating type, and coal, firewood are mostly used as fuel, and the structure is loose and complicated, thermal efficiency is low, seriously pollutes the environment. Contents of the invention [0003] The object of the present invention is to provide an extruder with compact and simple structure, high thermal efficiency and no environmental pollution. [0004] In order to achieve the above object, the present invention adopts an internal heating type puffing machine structure, which is composed of a frame, a drum, an electric heating rod, a transition mechanism, a driving mechanism and the like. The bottom of the drum is provided with a tubular bottom; one end is inserted into the tubular bottom a...
