Helical main shaft and water-entrained feather wringing dehydrator

Abstract

The invention relates to a helical main shaft and a water-entrained feather wringing dehydrator, and belongs to the technical field of processing equipment of feather albumen powder. The helical main shaft is characterized in that: screw blades of which the screw pitches are decreased progressively are arranged on a peripheral shaft wall; and the screw blades have two external-diameter dimensions and are arranged on the shaft wall from large to small. The water-entrained feather wringing dehydrator is characterized in that: a squeezing cavity formed by arranging squeezing strips with different sectional dimensions at intervals is formed at the periphery of the helical main shaft; a conical die head for blocking materials is arranged at the port of the squeezing cavity; helical blades of which the screw pitches are decreased progressively are arranged on the shaft wall of the helical main shaft; and the external-diameter dimensions of helical blades positioned in a feeding box are greater than those of the helical blades positioned in the squeezing cavity. In the helical main shaft and the water-entrained feather wringing dehydrator, the moisture content of feather can be greatly reduced, the production cost is reduced, and the production efficiency is high; and the helical main shaft and the water-entrained feather wringing dehydrator can be operated continuously and are difficult to block, slip and the like.

Description

technical field [0001] The invention relates to a screw main shaft and a water-carrying feather wringer and dehydrator adopting the main shaft, belonging to the technical field of wringer equipment. Background technique [0002] At present, in the production process of feather protein powder, raw material wet feathers (with a water content of 75-80%) enter the next process without dehydration treatment or simple dehydration treatment, resulting in the consumption of a large amount of thermal energy resources such as coal in the entire production process. And the production cycle is too long, and the existing dehydration equipment can only squeeze the moisture of wet feathers to 55-65%, and when the temperature is low in winter, it is prone to clogging and slipping, and cannot be operated continuously to affect production efficiency. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and pro...
