Method and device for preparing shrimp meat of euphausia superba

Abstract

The invention relates to the field of pretreatment of shrimps, in particular to a method and a device for quickly preparing shrimp meat of euphausia superba in shrimps. For the device for preparing the shrimp meat of the euphausia superba, on a machine frame (3), a motor (2) drives a centrifugal cylinder (5) to rotate around a vertical or a horizontal axis through a belt (4) or a chain; the wall of the centrifugal cylinder (5) is provided with a plurality of separated circular holes (5a), the pore diameter of the circular holes (5a) is 1 to 2 millimeters, the separation distance of the circular holes (5a) is 0.5 to 1 millimeter, the centrifugal force is 700 to 900 grams; and a fixed shell (1) for storing and taking the shrimp meat is arranged on the periphery of the centrifugal cylinder (5), wherein the centrifugal force RCF is equal to 0.00001118*R*N2, and N is the rotating speed and R is the semidiameter of the centrifugal cylinder (5) in the formula. The rotational time of the centrifugal cylinder (5) is 2 to 4 minutes. The diameter of the centrifugal cylinder (5) is 20 to 100 centimeters. The invention initiatively provides the method and the device for mechanically taking the shrimp meat of the euphausia superba in a rotational centrifugal mode, which have a high speed and a high yield, and ensure the completeness of the shrimp meat.

Description

technical field [0001] The invention relates to the field of shrimp pretreatment, in particular to a method and device for rapidly preparing shrimp meat from Antarctic krill among shrimps. Background technique [0002] Antarctic krill (Euphausia superba), as the largest single biological resource in the Southern Ocean, is an important group of marine zooplankton, supporting the populations of huge high-level predators such as penguins, seals, and cetaceans. According to the latest estimates, the biomass of Antarctic krill is 650-1000 million tons, and it has attracted increasing attention because of its huge biomass and potential fishery resources, as well as its special status in the Antarctic ecosystem. In 2000, the Committee for the Conservation of Antarctic Marine Resources (CCAMLR, 2000) revised the preventive catch limit of Antarctic krill from 1.5 million tons to 4 million tons, and the management catch limit was 620,000 tons. In the past five years, the annual catch...

Problems solved by technology

[0006] At present, domestic factories basically adopt the method of manual shelling for shelling and harvesting shrimp meat. The utilization of Antarctic krill is basically not shelled, and most of them are still limited to animal feed.

Only a few countries such as Japan have carried out comprehensive processing technologies such as krill shelling and meat extr
