Problems solved by technology

[0002] At present, the existing Antarctic krill ships in China basically use traditional fish meal processing lines to directly produce shrimp meal, or make shrimp meal after simple modification. The main equipment and technology are mainly traditional fish meal processing technology. The krill powder process does not take into account the biological characteristics of Antarctic krill, and the cooking process is longer, resulting in too fast decomposition of krill, and a large amount of protein is discharged with the wastewater generated by production, resulting in a lower product yield
A large amount of protein dissolves and loses, resulting in poor and unstable product quality
The waste water generated in the production process is not treated, a large number of high value-added products are lost, and resources are not well utilized

Embodiment Construction

[0020] A ship-borne Antarctic krill flour milling process, comprising the following steps:

[0021] (1) Material preparation stage: Antarctic krill is loaded into the material buffer tank 1, and is transferred from the material buffer tank 1 to the feed pump 2.

[0022] (2) Cooking stage:

[0023] a. The scraper heater 3 is heated, and the scraper heater 3 has high heating efficiency per unit area, and can quickly heat the material to 45°C. The material begins to coagulate slowly, and the heating time does not exceed three minutes.

[0024] b. Heating directly by the digester 4, using direct steam injection to quickly heat the material to 95°C, and the heating time does not exceed three minutes. The low-temperature protease in the material loses its activity at high temperature. The temperature of the heating stage of the whole digester is precisely controlled to ensure that most of the bacteria are killed and the quality of the product is stable.

[0025] The two-stage co...

Abstract

The invention relates to a ship-borne Antarctic krill powdering process. The process comprises the following steps: (1) material preparation: feeding Antarctic krill into a feeding pump, (2) scraper heater heating and digester heating, (3) material separation, (4) material drying, (5) material cooling, (6) material crushing, (7) liquid treatment, and (8) wastewater treatment. By adopting the production process of the invention, the yield of the product is obviously improved, the astaxanthin content and the protein content of the product are also obviously improved, and the quality of the product is significantly higher than that of shrimp powder produced by traditional methods. After the wastewater is evaporated, all resources in the entire process are fully utilized without any waste of resources.

Description

technical field [0001] The invention relates to the technical field of Antarctic krill production and processing, in particular to a ship-borne Antarctic krill powder making process. Background technique [0002] At present, the existing domestic Antarctic krill ships basically use the traditional fish meal processing line to directly produce shrimp meal, or make shrimp meal after simple modification. The main equipment and technology are mainly traditional fish meal processing technology. The krill meal process does not take into account the biological characteristics of Antarctic krill, and the cooking process is long, resulting in too fast decomposition of krill, and a large amount of protein is discharged along with the wastewater generated by production, resulting in a low product yield. A large amount of protein is dissolved and lost resulting in poor and unstable product quality. The waste water generated in the production process is not treated, a large number of hi...
