Fish descaling drum device and method based on horizontal multi-stage drum descaling equipment

Abstract

The invention relates to a fish scale removing drum device based on horizontal multi-stage drum scale removing equipment. A drum framework is composed of a plurality of rod-shaped or tubular sectionalmaterials which have an equal length and are arranged along a same circumference. A size of a scale through hole in a wall of a drum body is greater than a maximum shape size of a scale. Belt-shapedhelical blades are arranged on inner walls of the drum body and are configured to be a plurality of helical leads around a central axis. A plurality of scale removing structures are arranged on the belt-shaped helical blades, and the scale removing structures are arranged on surfaces of two sides of the entire lead length of the belt-shaped helical blades. Each scale removing structure intersectsat the central axis in a length direction of a strip shape of each scale removing structure so as to be arranged and installed firmly. The belt-shaped helical blades, scale removing structures A, scale removing structures B and walls of the drum body enclose a fish-passing helical channel similar to a dome-shaped tunnel. The fish-passing helical channel has a constantly rising helical shape aroundthe central axis, and fishes continuously advance and cross in a serpentine motion path in the fish-passing helical channel.

Description

technical field [0001] The invention relates to a descaling equipment for fish processing, in particular to a fish descaling roller device and method based on a horizontal multistage roller descaling equipment. Background technique [0002] The drum type descaling equipment is divided into three types: vertical rotation, inclined rotation and horizontal rotation. [0003] The researches at home and abroad and the existing descaling equipment are not high enough for the descaling efficiency and fish scale removal rate of fish processing, and the production efficiency is low. [0004] The publication number is CN103283806A, and the Chinese patent document published on September 11, 2013 discloses a "horizontal multi-stage drum descaling equipment and descaling method for processing bulk freshwater fish". The descaling equipment can continuously process fish However, there is no research on targeted residue-free removal of fish scales on the abdomen and back of fish. The desca...

[0003] Research at home and abroad and the existing descaling equipment are not high enough for the descaling efficiency and fish scale removal rate of fish processing, and the production efficiency is low

[0004] The publication number is CN103283806A, and the Chinese patent document published on September 11, 2013 discloses a "horizontal multi-stage drum descaling equipment and descaling method for processing bulk freshwater fish". The descaling equipment can continuously process fish products and improve production efficiency, but there is no targeted residue-free removal of fish scales on the abdomen and back of the fish body. The descaling effect still needs to be improved, and the technical methods also need to be improved
