Description

Technical Field

[0001] The utility model belongs to the technical field of aquatic product processing equipment, and particularly relates to a Artemia hatching device. Background Art

[0002] Artemia, also known as brine shrimp and Artemia, belongs to the phylum Arthropoda, subphylum Crustacea, class Crustacea, order Acropora, family Artemia, and genus Artemia. The yolk of the early larvae (nauplii) of Artemia contains a lot of protein, fat, and unsaturated fatty acids, making it a good bait for fish and shrimp fry. The egg shells after hatching can be collected for the extraction and preparation of chitin and chitosan. The brine shrimp eggs currently used for hatching are generally dried eggs and need to be incubated in an incubator for about 24 hours. During the incubation process, the salinity, temperature, dissolved oxygen and light intensity of the water body need to be maintained within an appropriate range. After hatching, the larvae and egg shells need to be separated to obtain Artemia larvae without impurities.

[0003] Currently, incubation devices used in existing technologies are generally cylindrical barrels with a funnel-shaped bottom and a drain pipe. They are also equipped with heating, oxygen supply, and lighting. When the incubation device is in use, oxygen supply to the barrel is stopped after the Artemia larvae have hatched. The larvae and egg shells are separated by gravity, and the larvae sink to the bottom of the barrel and can be collected through the drain pipe, while the egg shells remain inside. However, these incubation devices typically directly heat the water in the barrel, resulting in unstable and uneven temperature control within the barrel, which affects the Artemia hatch rate. Furthermore, after hatching, the larvae and egg shells must be collected and cleaned separately using separate tools, which is cumbersome and inefficient. Utility Model Content
