Problems solved by technology

At present, the processing technology of refined dry Artemia eggs processed at home and abroad is: in the process of processing, dead and alive Artemia eggs are not distinguished, and there are defects in the methods of removing impurities, washing and disinfection
The hatching rate of domestic Artemia eggs is 75%, the rate of drying Artemia eggs is 1:1.8, and the protein content is 17%. The worm rate is 1:2.8, and the protein content is 42%, but this technical index is not ideal either.

Embodiment 1

[0022] Take a batch of artemia egg wool, put it into the impurity removal mixer filled with 190‰ aqueous solution containing sodium chloride, after stirring, two sedimentation and stratification, discard the upper and lower layers of impurities. Collect Artemia eggs into 125-mesh wire mesh, rinse the Artemia eggs in the wire mesh with 8‰ calcium hypochlorite, rinse with fresh water after the washing liquid under the mesh is clear, and use a Φ800mm stainless steel centrifuge to remove the attached water from the Artemia eggs , and then send the Artemia eggs into the drier and dry them with hot air at 38°C until the water content in the eggs is 10%, and then use the farm windmill for active separation, and discard the dead eggs. Under the 5800LUX ultraviolet lamp, sterilize until the bacteria-free insects, that is, the refined dried artemia eggs. Take 1 kg of the refined dry artemia eggs, first prepare for hatching, and then hatch according to the general technology. The technic...

Embodiment 2

[0026] Take a batch of wet artemia eggs, throw them into the 200‰ sodium chloride aqueous solution and carry out the impurity removal treatment and calcium hypochlorite solution washing as in Example 1. Then use a bamboo sieve and a wire mesh bag to naturally remove the attached water of the Artemia eggs, and then send them to a dryer and dry them at a temperature of 39°C until the water content in the eggs is 6%. Then use an illumination intensity of 6000LUX ultraviolet light to sterilize and disinfect to aseptic insects. It is the refined dry Artemia eggs, take 1 kg of refined dry Artemia eggs for hatching, the results are as follows:

[0027] The hatching rate was 94%, 3.2 kg of Artemia were produced, and the protein and lipid content in Artemia eggs was 54%.

Abstract

The present invention relates to a processing method of refined dried Brine shrimp Eggs. Said method includes the following steps: using 180-200 % sodium chloride aqueous solution and fresh water to separate and remove impurities at twice, then using 0.8% calcium hypochlorite solution as rinse solution to make rinsing, at the same time having the sterilizing action, and drying the Brine Shrimp Eggs to make its water content be 5-15%. Said invention has active separation procedure, uses air blast process to separate out dead eggs, then uses 5800-6200 LUX UV-ray lamp to make sterilization and disinfection, its Brine Shrimp Eggs hatching rate is 92-94%, the Brine Shrimp natality is 1:3.1-3.2, and its Brine Shrimp protein content is 52-54%.

Description

technical field [0001] The invention relates to the technical field of processing dried artemia eggs as open bait in the aquaculture industry, in particular to the processing technology of refined dried artemia eggs. Background technique [0002] Artemia is the opening bait for fish, shrimp and crab seedlings in aquaculture. Artemia is hatched from Artemia eggs. Artemia eggs are divided into dry and wet; dry Artemia eggs are divided into wool and refined materials. At present, the problems in the processing technology of the refined dried Artemia eggs processed at home and abroad are: in the process of processing, dead and alive Artemia eggs are not distinguished, and there are defects in the methods of removing impurities, washing and disinfection. The brine solution used by relevant units at home and abroad to remove impurities contains about 300‰ of sodium chloride, and the water content of Artemia eggs is high after stratification. Rinsing ...
