Embodiment Construction

[0018] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , 2 As shown, the screw rod 1 of the present invention is designed with an outer helix, and the helical sleeve 2 is designed with an inner helix that is consistent with the helical direction of the screw rod 1, and the outer helix of the screw rod 1 and the inner helix of the helical sleeve 2 are all composed of 3-4 Strips isometric spiral composition.

[0020] One end of the screw rod 1 has a shaft hole 3 and a pin opening 4 for connecting with the power shaft 5. The depth of the outer spiral groove gradually becomes shallower from the shaft hole 3 end to the top end, and when it reaches the top of the screw rod 1 , the depth of the outer helical groove remains constant at the minimum size to form a section of plateau A.

[0021] One end of the spiral sleeve 2 has a feed hole 6, and the depth of the inner spiral groov...

Abstract

The invention relates to a crew rod and a scroll cover of a bulking machine. The screw rod is provided with an outer spiral; the scroll cover is provided with an inner spiral having a consistent spiral direction as the screw rod; the outer spiral of the screw rod and the inner spiral of the scroll cover both comprise 3-4 isometric spirals; and the depth of an outer spiral groove of the screw rod and an inner spiral groove of the scroll cover gradually turn shallow towards a top direction, and nearing the tops of the screw rod and the scroll cover, the depths of the spiral grooves keep at an unchanged minimum size to form stationary segments. The screw rod and scroll cover provided by the invention are applied to the bulking machine, can substantially reduce electric energy consumption of the bulking machine, reduce volume of the whole machine and production and equipment costs, raise production efficiency and avoid machine blocking fault.

Description

technical field [0001] The invention relates to a screw rod and a screw sleeve of an extruder, belonging to the field of food processing machinery. Background technique [0002] Since the advent of the puffing machine, puffing technology, as an economical and practical new processing method, is widely used in food or feed processing and has developed rapidly. The puffing machine can complete the mixing, crushing, extrusion, aging and sterilization of materials at one time , molding and other processes to process puffed products. Compared with traditional production processes, puffed technology has greatly improved the processing technology of grain products and shortened the process. It not only changes the physical state and internal structure of the product, but also makes starch , The protein is easier to digest and absorb, and the taste of the product is improved, and the quality of the product is improved. [0003] Extruders are mainly divided into two types: single-sc...
