Abstract:
The present invention relates to a continuous on-board drying method for Antarctic krill and a continuous on-board processing method of shelled Antarctic krill. The drying method includes the following steps: 1) subjecting fishing materials to cleaning, sorting, and dewatering with a vibrating screen; 2) rapidly heating the krill to the temperature of up to 70° C. using infra-red rays; 3) hot-air drying; 4) impurity removal by vacuum; 5) cooling to obtain dried krill. The processing method includes the following steps: a) subjecting fishing materials to cleaning, sorting, and dewatering with a vibrating screen; b) rapidly heating the krill to the temperature of up to 70° C. using infra-red rays; c) hot-air drying; d) subjecting the dried krill to shelling treatment to separate shell from meat, to obtain shelled krill; e) impurity removal by vacuum to obtain shelled krill product. The methods in the present invention are highly efficient, energy saving, green and environmental protection, and the krill products have high quality and safety.

Claim (Index 6):
The method according to  claim 1 , further comprising the treatment of the replaced cooking soup produced in step 2), which is carried out as follows:\n (a) the replaced cooking soup (i.e., the cooking wastewater) produced in step 2) is cooled down to 0\u02dc70\u00b0 C., the cooled cooking wastewater is subjected to filtration or centrifugation to remove the suspended substances, then a flocculant is added and stirred for 5\u02dc60 min, and then the resulted floccule is removed by filtration or centrifugation; wherein the flocculant is diatomite, and the addition amount of the diatomite is 50\u02dc1000 mg/L; (b) microfiltration treatment: a microfiltration membrane with aperture of 0.1\u02dc2 \u03bcm is used for filtration of the cooking wastewater obtained in step (a), and a permeate solution \u201ca\u201d is obtained; (c) ultrafiltration treatment: a ultrafiltration membrane with aperture of 10000\u02dc100000 Da is used for filtration of the permeate solution \u201ca\u201d, and a permeate solution \u201cb\u201d is obtained; (d) purification treatment: the permeate solution \u201cb\u201d is subjected to one of the following treatments: {circle around (1)} nanofiltration treatment: the permeate solution \u201cb\u201d flows into a nanofiltration membrane device with aperture of 90\u02dc1000 Da, and is subjected to filtration under conditions of 0.5\u02dc2 MPa and 0\u02dc70\u00b0 C. to obtain a permeate solution \u201cc\u201d, and the solution \u201cc\u201d can be recycled or discharged directly; {circle around (2)} reverse osmosis treatment: the permeate solution \u201cb\u201d flows into a reverse osmosis device, and is subjected to reverse osmosis treatment under conditions of 1\u02dc6 MPa and 0\u02dc70\u00b0 C. to obtain a permeate solution \u201cd\u201d, and the solution \u201cd\u201d can be recycled or discharged directly.
