Problems solved by technology

Due to the high viscosity of potato residues, the current general-purpose waste residue dehydration equipment, such as screw presses, centrifugal dehydrators, plate and frame filter presses, belt filter presses, etc., cannot achieve the desired dehydration effect, and usually can only dewater 70%, and the energy consumption is relatively high. Therefore, the equipment for how to quickly dehydrate and dry potato residues is particularly important in the processing of potato by-products

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] The hollow tube type variable-pitch screw conveyor for potato residue dehydration equipment includes a screw 1 and a screw blade 2 arranged on the screw 1, wherein the conveyor is mainly composed of a dense helical section 3 located at the front end of the screw 1 and a wide helix located in the middle of the screw 1 Segment 4 and reverse helical segment 5 located at the end of screw 1.

[0020] as attached figure 1 As shown, there is a hollow pipe 6 inside the screw 1, and the hollow pipe 6 runs through the entire screw 1 and is connected with external equipment; the dense spiral section 3 and the reverse spiral section 5 are respectively provided with a first air hole 7 and a second air hole 8; The diameter of the first air holes 7 is smaller than that of the second air holes 8 , and the distribution density of the first air holes 7 is greater than that of the sec...

Abstract

The invention belongs to the technical field of potato pulp dewatering devices, and particularly relates to a hollow tube type variable-pitch spiral conveyor for a potato pulp dewatering device. The spiral conveyor comprises a screw (1) and screw blades (2) arranged on the screw (1) and is mainly composed of a dense spiral section (3) located at the front end of the screw (1), a wide spiral section (4) located in the middle of the screw (1) and a reverse acting spiral section (5) located at the tail end of the screw (1). The spiral conveyor is characterized in that a hollow pipeline (6) is arranged in the screw (1), and the hollow pipeline (6) penetrates through the whole screw (1) and is connected with external equipment. The spiral conveyor has the advantages that bearing blocking is prevented, long-time stable and continuous spiral conveyance is guaranteed, and potato pulp is pressurized and heated to be dried through external hot air.

Description

technical field [0001] The invention belongs to the technical field of potato dregs dehydration equipment, and in particular relates to a hollow tube type variable-pitch screw conveyor for potato dregs dehydration equipment. Background technique [0002] Starch is mainly produced through deep processing of corn, cassava, potato, sweet potato, wheat, etc. Corn is the main raw material for processing. The products produced by further extending the industrial chain of starch through deep processing mainly include: starch sugar, lysine, sorbitol, chemical alcohol, fuel ethanol, citric acid, etc. There are more than 2,000 kinds of products produced by deep processing of corn in the world, while there are only more than 400 kinds of deep-processed corn products in my country. [0003] Due to the obvious value-added benefits of corn deep processing, in recent years, the expansion and reconstruction of global corn deep processing has been very positive. The wide application of co...
