Embodiment 1

[0018] Antarctic krill shrimp shell powder is mixed with potato starch, so that the mass content of Antarctic krill powder in the mixed material is 90%. The moisture content of the mixed material is adjusted so that the water content of the mixed material entering the extrusion granulator is 20%. Input the mixed material into the extrusion puffing granulator for puffing and granulation. The granulation temperature is 110°C, the die head pressure is 90Bar, and the cutter rotation number at the granulation end of the granulator is adjusted to make the cut Antarctic krill powder The length of the extruded material is 5mm, and the powder degree of the material after granulation is 3.64% (through a 28-mesh sieve). Use a dryer to adjust the moisture content of the extruded material so that the material has a moisture content of 4%, and then feed the material into a ring extractor, use n-hexane as the leaching solvent, and use the general oil leaching process for leaching to extract ...

Embodiment 2

[0020] Antarctic krill shelled shrimp powder is mixed with cornstarch, so that the mass content of Antarctic krill powder in the mixed material is 80%. The moisture content of the mixed material is adjusted so that the water content of the mixed material entering the extruding puffing granulator is 18%. Input the mixed material into the extruding puffing granulator for puffing and granulation. The granulation temperature is 105°C, the die head pressure is 15Bar, and the cutter rotation number at the granulation end of the granulator is adjusted so that the Antarctic krill meal after cutting The length of the extruded material is 7mm, and the powder degree of the material after granulation is 2.95% (through a 28-mesh sieve). Use a dryer to adjust the moisture content of the extruded material so that the material has a moisture content of 8%, and then feed the material into a ring extractor, use ethanol as the leaching solvent, and perform leaching according to the general oil l...

Embodiment 3

[0022] Moisture adjustment is carried out on the Antarctic krill whole shrimp powder, so that the moisture content of the material entering the extrusion extruder granulator is 22%. Input the mixed material into the extrusion puffing granulator for puffing and granulation. The granulation temperature is 120°C and the die head pressure is 126Bar. The length of the extruded material is 6mm, and the powder degree of the material after granulation is 8.12% (through a 28-mesh sieve). Use a dryer to adjust the moisture content of the extruded material, so that the moisture content of the material entering the extraction equipment is 12%, and then the material is input into the ring extractor, using ethanol as the extraction solvent, and leaching is carried out according to the general oil extraction process to extract Antarctic krill oil.

Abstract

The invention discloses a method for extracting shrimp sauce from euphausia superba powder by bulking, prilling and leaching. The method is characterized by comprising the steps of: 1, mixing euphausia superba powder with starch or plant material powder rich in starch, wherein the weight percentage of euphausia superba powder is 50-100%; 2, adjusting water of mixed material till the water content is 10-40%; 3, importing the mixed material to an extrusion priller to bulk and prill to obtain bulked particles which are 2-10mm long, wherein the prilling temperature is 80-140 DEG C and the die head pressure is 10-120Bar; 4, adjusting water of the bulked particles by a drier till the water content is 4-12%; and 5, importing the bulked particles into a fat leaching device to extract euphausia superba sauce. The method provided by the invention has the characteristic of good prilling effect.

Description

technical field [0001] The invention relates to the deep processing of Antarctic krill oil, more specifically, relates to the extraction of shrimp oil. Background technique [0002] Antarctic krill (Euphausia superba) is one of the largest single species of biological resources on the earth. Its stock is estimated to be about 400-1.5 billion tons, and the annual output of mature shrimp is 300-500 million tons, and the annual catch can reach About 100 million tons, forming a huge potential fishery resource. In recent years, with the gradual depletion of world-wide traditional fishery resources and the proposal of a 200 nautical mile exclusive economic zone, the huge Antarctic krill resources in Antarctic waters have attracted the attention of some pelagic fishery developed countries. my country has also included Antarctic krill resources as one of the main development species for the future development of pelagic fisheries. [0003] Antarctic krill live in cold waters, and ...
