Embodiment 1

[0020] Collect low-value small miscellaneous fish, or the head, skin, viscera and fish processing waste of horse-faced puffer, and crush them for later use. Add 50% formic acid aqueous solution to the pulverized raw material, stir and mix, stand still, and liquefy at a temperature of 30-35° C. for 1-2 days. The liquid obtained after liquefaction is heated up to 60°C, and the oil is removed by centrifugation with a centrifugal sedimentation machine to obtain liquefied fish feed. The yield of liquefied fish feed is 90.7%. In addition, there is still fish oil with a yield of 7.3%.

Embodiment 2

[0022] Collect low-value small miscellaneous fish, or the head, skin, viscera and fish processing waste of horse-faced puffer, and crush them for later use. Add 50% formic acid aqueous solution to the pulverized raw material, stir and mix, stand still, and liquefy at a temperature of 30-35° C. for 1-2 days. The liquid obtained after liquefaction is separated by a centrifuge to obtain slag and crude filtrate; the crude filtrate is then separated by an oil separator to obtain fish oil, liquid and a small amount of slag, and the liquid is combined with the slag separated by the first centrifuge to obtain liquefaction fish food. The yield of liquefied fish feed is 83.5%. In addition, there is still fish oil with a yield of 5.6%.

Embodiment 3

[0024] Collect low-value small miscellaneous fish, or the head, skin, viscera and fish processing waste of horse-faced puffer, and crush them for later use. Add 50% formic acid aqueous solution to the pulverized raw material, stir and mix, stand still, and liquefy at a temperature of 30-35° C. for 1-2 days. When processing horse-faced puffer, the blunt viscera of the horse-faced puffer is placed separately from other wastes such as heads and skins, and they are crushed, acidified and liquefied respectively; The liquid and sediment are combined with the liquid obtained after liquefaction of other wastes such as scalp to obtain liquefied fish feed. The yield of liquefied fish feed is 95.7%. In addition, there is still fish oil with a yield of 5.3%.

Abstract

The present invention belongs to the technical field of aquatic product processing, and particularly relates to a method for the comprehensive utilization of Navodon modestus waste. The method includes the following steps: A, pretreatment: collecting heads, skin, viscera and fish product processing waste of the Navodon modestus, and crushing the collected materials for further usage; B, liquefaction: adding formic acid solution into the crushed raw materials, evenly stirring and mixing the formic acid solution treated materials, and standing the mixture to be liquefied; and C, degrease: subjecting the liquid obtained after liquefaction to degreasing treatment to obtain liquefied fish feed and cod liver oil, respectively. The method realizes the comprehensive utilization of Navodon modestus waste resources, and can process the Navodon modestus waste into the liquefied fish feed and the cod liver oil. By adopting the method, products with high economic value are obtained, and environmental pollution is solved at the same time.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a method for comprehensively utilizing horse-faced fish waste. Background technique [0002] In recent years, the output of horse-faced fish has been increasing continuously, and its output is second only to hairtail, ranking second in the national fish output. The annual output of horse-faced fish in Shanghai is 50,000 to 60,000 tons. The edible part of horse-faced puffer accounts for less than 50%. If its waste is not disposed of in time, it will easily cause environmental pollution, and sometimes the hunting of horse-faced fish has to be stopped in advance, which affects production. In order to solve environmental pollution and promote fishery production, a study on the utilization of horse-faced fish waste was carried out. [0003] The invention explores a method for comprehensive utilization of the horse-faced fish waste to obtain high econo...
