A fish fertilized egg debonding and cleaning system and its technological process

Abstract

The invention relates to a fish germ cell mucus removing and washing system. The fish germ cell mucus removing and washing system is characterized by comprising a mucus removal liquid mixing and supplying device, a mucus removing and washing apparatus and a fish roe collector. The mucus removing and washing apparatus comprises a mucus removing and washing barrel. A rotary stirring device is arranged at the center of the mucus removing and washing barrel, the lower end of the mucus removing and washing barrel is provided with an opening which is communicated with the fish roe collector, a clean water inlet pipe and a mucus removal liquid inlet pipe through a four-way connecting pipe, an overflow ring slot is fixedly arranged on the upper portion of the outer side wall of the mucus removing and washing barrel, and a mucus removal waste water outlet is arranged on the lower portion of the overflow ring slot. A spraying ring pipe is arranged above the mucus removing and washing barrel and provided with spraying holes which align to the upper end port of the mucus removing and washing barrel. A screen ring is arranged above the mucus removing and washing barrel and isolates the upper end of the mucus removing and washing barrel from the overflow ring slot. A liquid outlet of the mucus removal liquid mixing and supplying device is communicated with the mucus removal liquid inlet pipe. A liquid inlet pump is arranged in the liquid inlet pipe and provides liquid inlet power, and a water inlet pump is arranged on the clean water inlet pipe and provides water inlet power.

Description

technical field [0001] The invention relates to a fish fertilized egg debonding and cleaning system and a process flow thereof, belonging to the technical field of aquaculture. Background technique [0002] Among the important traditional cultured fishes in China, most of them produce sticky eggs. Before artificial hatching, it is necessary to debond and wash the fertilized eggs to improve the hatching rate. [0003] At present, the debonding and cleaning of viscous zygotes mostly rely on manual operations. The main problems are: ①uneven and incomplete debonding; ②high damage rate of fish eggs; ③fertilized eggs are susceptible to artificial infection and pollution; ④manual operation is labor-intensive, with low output and efficiency; ⑤high requirements for operators , it is difficult to achieve standardized standard operation. [0004] And the recently appeared method of applying the principle of aeration to carry out debonding of fertilized eggs, this method is to pass h...

AI Technical Summary

Problems solved by technology

The main problems are: ①uneven and incomplete debonding; ②high damage rate of fish eggs; ③fertilized eggs are susceptible to artificial infection and pollution; ④manual operation is labor-intensive, with low output and efficiency; ⑤high requirements for operators , it is difficult to achieve standardized standard operation

[0004] And the recently appeared method of applying the principle of aeration to carry out debonding of fertilized eggs, this method is to pass high-pressure gas in the container containing clear water and fertilized eggs, so that the fertilized eggs adhered together will be crushed under the impact of air flow and water flow. This method has the following problems: the fish eggs are not evenly turned and there are dead angles; after long-term use, the aeration holes are easy to block, which affects its use effect; high-pressure gas is easy to damage the fish eggs, causing unnecessary losses
