Insect Powder Feed Freeze-Drying Mass Loss Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional freeze-drying of meat or fish results in significant mass loss, leading to a substantial reduction in the amount of feed produced.
Innovation Solution
Using insects or insect powder as a raw material instead of meat or fish, combined with starch and other additives, to create a feed that minimizes mass loss during the freeze-drying process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If meat or fish is used as raw material for freeze-dried feed, then protein source is provided, but mass loss occurs reducing feed production amount
Solution Approach 1:
The patent changes the raw material parameter from meat/fish to insects, which have different moisture content and protein composition. This parameter change results in reduced mass loss during freeze-drying while maintaining protein quality, thereby increasing feed production amount.
Solution Approach 2:
The patent uses a composite formulation combining insect powder with starch and other ingredients. This composite approach allows the insect protein to serve as a concentrated protein source with lower moisture content, reducing overall mass loss during the freeze-drying process while maintaining nutritional value.
2Quantity of substance
If meat or fish is used as raw material, then protein is supplied, but the mass is reduced to 1/5 after freeze-drying
Solution Approach 1:
The patent changes the raw material from meat/fish to insects, which have inherently lower moisture content and higher protein concentration. This parameter change results in minimal mass reduction (only about 1/10) after freeze-drying compared to the 1/5 reduction seen with meat or fish, while maintaining high protein content in the final feed.
3Loss of energy
If conventional freeze-drying is used, then drying is achieved, but significant mass loss occurs
Solution Approach 1:
The patent changes the raw material parameter to insects, which have lower initial moisture content and higher protein concentration. This results in significantly reduced mass loss during freeze-drying (only about 10% compared to 50-80% loss with meat/fish), thereby improving feed production efficiency and productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method maximizes the amount of feed produced while maintaining nutritional value, offering a more efficient and sustainable alternative to traditional feed production.
Implementation Method 1
the atmospheric pressure around the object is lowered to sublimate the solid-phase water contained in the object to a gaseous phase to dry the object
Implementation Method 2
The freeze-drying technique dries the object by sublimating the ice by supplying thermal energy to the frozen object
