Horizontal multistage roller scaling apparatus for processing large number of freshwater fish, and scaling method thereof

Abstract

The invention relates to a horizontal multistage roller scaling apparatus for processing a large number of freshwater fish, and a scaling method thereof. Fish for processing is continuously conveyed to a rotating multistage roller, scales are removed through scaling structure members having diversified shapes on the inner walls of all-stage rollers, a plurality of axial spiral channels are arranged on the inner wall of each of cylindrical connecting pieces and can push the fish to a next-stage scaling roller from a previous-stage scaling roller, a hairbrush roller shafting and the multistage roller are coaxially arranged and are driven by two variable-frequency speed control power devices having different powers at the upper portion of a frame, the rotating speed and the turning direction of the hairbrush roller shafting are mutually associated and coupled, a plurality of hairbrush rollers in the hairbrush roller shafting can realize the scaling assistance and the feeding control of the fish, scales removed from the surface of the fish go through scale through holes on the all-stage scaling rollers and fall in a scale deposition tank for convenient collection, and pressurized water flow in a central tube shaft goes through a plurality of small holes arranged on the wall of the central tube shaft and sprays the processed fish in the multistage roller for flushing.

Description

technical field [0001] The invention relates to a descaling equipment for fish processing and a descaling method thereof, in particular to a horizontal multistage drum descaling equipment for processing freshwater fish and a descaling method thereof. Background technique [0002] China's freshwater fish production ranks first in the world, reaching 21.099 million tons in 2009. Mechanized descaling is a key and difficult point in the pre-processing of bulk freshwater fish, especially silver carp. Mechanized descaling equipment can greatly improve the processing efficiency of freshwater fish, and at the same time, it is more conducive to the centralized collection and full utilization of fish scale waste resources. [0003] Foreign countries have mainly developed some equipment for descaling seawater fish, but the applicability and descaling effect are not good when they are used to process domestic bulk freshwater fish. At present, the descaling method of freshwater fish pro...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is: most of the existing descaling equipment uses one roller, the descaling structural parts are single, the descaling effect is not good, and only small batches and intermittent loading and unloading can be carried out, and continuous descaling is not realized. Feeding and automatic operation, low production efficiency and low descaling rate
