Viscus removing device for processing small fishes

Abstract

The invention relates to a device applied to viscus removal of fishes and belongs to the field of fish processing. A viscus removing device for processing small fishes comprises feeders for sequentially conveying fish bodies, a clamp roller pair rotation mechanism and a bevel gear pair or cone-shaped roller pair rotation mechanism. The feeders tidy and discharge the fish bodies with fish head not completely cut off, the clamp roller pair rotation mechanism is composed of a pair of parallelly arranged long cone-shaped clamp rollers and a transmission component of the clamp rollers, and the bevel gear pair or cone-shaped roller pair rotation mechanism is composed of a pair of short-axis large-bottom-diameter bevel gears vertically arranged on the conveyed fish bodies or cone-shaped rollers and a transmission component of the bevel gears or the cone-shaped rollers. Gaps arranged between a clamp roller pair and gaps arranged between a bevel gear pair or a cone-shaped roller pair are connected to form a channel, the fish bodies fall into the gaps between a long cone-shaped clamp roller pair to be clamped and conveyed downwards, the fish heads fall into the gaps between the short-axis large-bottom-diameter bevel gear pair or the cone-shaped roller pair to be clamped and pulled upwards, and the fish heads drive involved tissues and fish viscus to be separated from the fish bodies.

Description

technical field [0001] The invention relates to a mechanical device for fish processing, in particular to a visceral removal device applied to small fish processing. Background technique [0002] Small fish, commonly known as "small miscellaneous fish", usually refer to small and low-value marine fishes, which are characterized by: many varieties, large differences in body characteristics, large output, and low market prices. In order to make good use of such low-value marine fishery resources, the small miscellaneous fish are usually treated first by removing the head and viscera, and then the rinsed fish body is used to process frozen surimi, various surimi products, and fish oil health products. and seasoned snack foods and other deep-processed products, while discarded fish heads, viscera and bone spurs and other leftovers are used to process fish meal. [0003] Although the operation method of artificially removing the head and viscera of small fish is simple, due to t...

AI Technical Summary

Problems solved by technology

Although there are specialized fish head and viscera processing equipment at home and abroad, they are all developed for large-scale commercial fish with a length of more than 30 cm. Most of these equipment are special-purpose machines with poor versatility. There are strict restrictions, and its complex structure, large size, poor adaptability and high price can not meet the actual needs of the production and processing of low-value small trash fish with many varieties and large individual differences.
