Description

Crab degreasing device for easy removal of gills

The present invention relates to a crab detachment device that is easy to remove gills, and more particularly, to reduce the manual labor required for gill removal by quickly and easily removing gills by spraying high pressure water onto the crab from which the shells and back shells have been removed. Crab easy to remove gills that reduce the defect rate and the loss of crab meat generated during operation relates to a crab stripper device.

The crab, which is known to inhabit more than 4,500 species worldwide and 183 species in Korea, has ten legs and is classified as a deciduous tree among arthropod crustaceans. The ten legs are functionally divided into a pair of claws and four pairs of walking legs. Crab are as diverse as their habitat and appearance. Crabs are also called ocean sweepers because they have a vegetation that crawls on the ground and handles the carcasses of marine life falling to the bottom.

These crabs are one of the important fishery resources of Korea, where the three sides are the sea, or they are steamed, boiled in boiling water, applied to the body or legs, or aged using soy sauce to eat. As the number is greatly increased, it is processed and sold in various forms such as crab meat and various frozen foods.

However, in order to process the crab into a variety of processed foods, it is necessary to sort the flesh with different flavors in the hard shell of the crab.

Therefore, conventionally, a worker takes a cutting knife and cuts the crab by the body, the general leg, and the tong leg by hand on the workbench, and requires a lot of labor, and the worker cuts the hard crab shell by the knife by hand. There was a frequent problem that the worker was injured by the shell or knife of the crab in the process.

In addition, in order to improve inconvenience caused by manual work, a processing apparatus capable of automatically processing crabs has been proposed as in Korean Laid-Open Patent No. 1997-0032404.

However, such a crab processing device simply removes and cuts the pear shell or the back shell, and many problems have occurred in the gill removal portion of the crab having the largest workmanship in the crab processing.

In Korean Laid-Open Patent No. 1997-0032404, the gills are removed by installing a rotary brush at the rear end of the de-axle shaft to remove the gills to remove the gills, but when the position of the rotary brush is too low, the gills can be completely removed. The problem is that the crab meat part of the body is lost, and if the position of the rotary brush is too high, the crab meat can be reduced, but the gills are not removed properly, so that the worker separates the crushed gill part from the subsequent process. Inconvenience to perform the work occurs.

This is due to the inherent limitation of the optimization of the work by adjusting the position of the rotary brush as the gill crab body is formed at the lowest edge of the dome-shaped body.

In addition, the type of crab and the shape and size of the crab are different, so it is impossible to set the position of the rotating brush that can be used for all the various crabs.

Therefore, the current situation is currently in domestic or overseas, but the degreasing process, the trunk cutting or the separation of the leg portion is performed through an automated device, but the gill removal process is performed by the worker due to the concern of crab loss and the high defect rate of gill removal. Is being removed.

As a result, in the working environment where a large amount of crab processing must be performed within a relatively short time, many workers manually remove the gills of the crab from the degreasing process, which makes it difficult to secure manpower and increases labor costs. A decrease in yield occurs.
