Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excrement-drying systems in livestock barns are inefficient due to high energy consumption and inadequate aeration, leading to suboptimal drying and ammonia formation.
Innovation Solution
An excrement-drying device with a segmented excrement transportation belt, where air is selectively applied to only a portion of the belt, reducing energy usage and improving airflow, allowing for more efficient drying and minimizing ammonia creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the aeration device extends across the entire length of the excrement transportation belt, then the excrement is exposed to air for drying, but a very large amount of air is introduced leading to high energy consumption
Solution Approach 1:
The excrement transportation belt is divided into multiple sections, and the aeration device is applied only to specific segments rather than the entire length. This segmentation allows air to be introduced only where needed, reducing overall air consumption and energy usage while maintaining effective drying in the treated zones.
Solution Approach 2:
The aeration device is positioned to provide localized air introduction at specific points along the transportation belt. This creates zones of high air flow exactly where excrement needs drying, rather than uniformly distributing air across the entire belt length, thereby reducing total energy consumption while maintaining drying effectiveness.
2Productivity
If the aeration device extends across the entire length of the excrement transportation belt, then air is introduced for drying, but the excrement is not particularly well aerated
Solution Approach 1:
The transportation belt is segmented into multiple zones, with aeration devices positioned at specific segments. This segmentation creates concentrated air introduction points that provide better local aeration to the excrement, improving drying efficiency compared to diffuse air distribution across the entire belt.
Solution Approach 2:
The aeration device operates in periodic cycles, introducing air at regular intervals along the transportation belt. This periodic action ensures that excrement passes through multiple aeration zones during its conveyance, enhancing overall drying efficiency through repeated exposure to air flow.
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 system operates economically with reduced energy consumption, enhanced drying efficiency, and lower ammonia production, enabling continuous operation without the need for extensive exhaust air purification systems.
Implementation Method 1
at least one air nozzle or a multiplicity of air nozzles for spraying air onto the excrement lying on the excrement transportation belt

AI summary
An excrement-drying device (1) for animal stalls, such as poultry stalls, comprises an excrement conveyor belt (2) for conveying the excrement along a conveying direction (F), wherein the excrement conveyor belt (2) extends over a conveying length (L) and has a top side (10) for receiving the excrement (K), and a drying unit (3) with at least one discharge element (4), which has at least one air nozzle (5) for blowing air onto the excrement (K) lying on the excrement conveyor belt (2) in order to dry the excrement (K). The top side (10) for receiving the excrement (K) of the excrement conveyor belt (2) is divided into several excrement conveyor belt sections (TB1, TB2) arranged one after the other in the conveying direction (F); and the at least one discharge element (4) is arranged in such a way that air is blown onto only one of said excrement conveyor belt sections (TB1, TB2).
