Euphausia superba pulverizing system and application thereof

Abstract

The invention provides a euphausia superba pulverizing system and an application thereof. The euphausia superba pulverizing system comprises a crushing unit, a multi-stage cooking unit, a separating and squeezing unit and a vacuum freeze-drying unit which are connected in sequence. Wherein the multi-stage cooking unit comprises a first-stage cooking module and a second-stage cooking module; the separating and squeezing unit comprises a horizontal centrifugal module, a squeezing module and a butterfly centrifugal module; wherein a solid-phase discharge port of the horizontal centrifugal moduleis connected with a feed port of the squeezing module, a liquid-phase discharge port of the horizontal centrifugal module and a liquid-phase discharge port of the squeezing module are connected with the butterfly centrifugal module, and solid-phase discharge ports of the squeezing module and the butterfly centrifugal module are respectively connected with the vacuum freeze-drying unit. When the system is used for preparing the euphausia superba powder, the euphausia superba powder with the water content lower than 10% can be obtained, and the nutritional ingredients are not influenced.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a powder-making system, in particular to an Antarctic krill powder-making system and its application. Background technique [0002] According to marine surveys, there are 1 to 1.5 billion tons of krill resources in the Southern Ocean, which is the region with the most abundant marine biological resources on the earth. In addition to the natural feeding and consumption of the Antarctic ecosystem, in theory, humans can capture one-tenth of the krill stock from the Southern Ocean every year, that is, 100-150 million tons of krill resources, without affecting the Antarctic ecosystem balance , so Antarctic krill resources are a huge protein warehouse. [0003] As a potential and huge protein storehouse for humans, the commercial development of Antarctic krill has long attracted people's attention. Krill also has huge potential medicinal value. Antarctic krill is rich in Omega-3...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many methods for Antarctic krill drying, such as sun-drying, drying, etc., but these drying methods are carried out at a temperature above 0°C or higher, and some nutrients in the dried product are not only oxidized , most of some volatile nutrients will be lost, some heat-sensitive substances, such as proteins and vitamins, will be denatured, microorganisms will lose their biological vitality, and the dried substances are not easy to dissolve in water, etc. Therefore, the dried product is the same as before drying There is a big difference in properties, the color is not uniform, and the color difference is very large

At the same time, the moisture content of krill powder produced by traditional drying process is above 20%. If krill powder with moisture content below 10% is required, it needs to be dried in a smoke tube boiler above 360°C. However, most of the nutrients in the krill meal with this moisture content have changed in character
