Brine Shrimp Feed Preparation With Eggshell Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing brine shrimp feed for tropical fish are inefficient, leading to contamination, indigestion, and ascites in fish due to unhatched eggs and eggshells, and require cumbersome collection processes.
Innovation Solution
A method involving culture saline water preparation, brine shrimp hatching, spirulina and Haematococcus powder injection, eggshell separation, and freezing to produce a tropical fish feed that promotes growth and strengthens immunity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brine shrimp eggs are hatched using conventional methods, then hatched brine shrimp can be obtained as feed, but unhatched eggs and eggshells contaminate the feed causing indigestion and ascites in fish
Solution Approach 1:
The patent extracts and removes eggshells from the brine shrimp culture medium using a specific collection device that separates eggshells from hatched brine shrimp based on their different physical properties (floating vs. sinking behavior), thereby eliminating the harmful contamination source
Solution Approach 2:
The patent introduces a collection device as an intermediary tool between the hatching process and feed collection, which acts as a mediator to separate and remove eggshells, preventing them from contaminating the final feed product
2Productivity
If conventional collection methods are used, then some hatched brine shrimp can be collected, but the collection process is cumbersome and requires repeated operations reducing productivity
Solution Approach 1:
The patent segments the collection process into distinct functional zones within the collection device: an introduction portion for receiving culture medium, a separation portion for dividing brine shrimp from eggshells based on their movement patterns, and a collection portion for gathering the purified feed, enabling continuous one-step collection
Solution Approach 2:
The collection device utilizes the natural self-movement characteristics of hatched brine shrimp (swimming toward light) to automatically separate them from eggshells without requiring external intervention or repeated operations, making the system self-operating
3Quantity of substance
If brine shrimp are kept alive for feed, then high nutritional value is maintained, but storage life is limited and refrigeration is required
Solution Approach 1:
The patent changes the physiological state parameter of brine shrimp from alive to frozen, which fundamentally alters their storage characteristics while preserving their nutritional value, allowing for long-term storage without refrigeration
