Poultry Dropping Drying Fan with Pivotable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing poultry management devices face inefficiencies in drying poultry droppings due to high energy losses and poor drying uniformity, particularly because of the need for long air ducts that result in friction-related pressure losses, leading to suboptimal drying performance and increased ammonia emissions.
Innovation Solution
A poultry management device with a pivotable fan element mounted at an angle of 45° to 90° relative to the collection face, which enables efficient air movement and water absorption, reducing drying time, energy consumption, and ammonia emissions by utilizing existing space and minimizing friction losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a drying device with air duct and radial blowers is used to direct air stream onto poultry droppings, then drying of droppings is achieved, but significant pressure losses occur due to friction in long air ducts, resulting in poor energy efficiency
Solution Approach 1:
The invention extracts the drying function from a centralized remote drying system with long air ducts and distributes it to individual pivotable fan elements positioned directly at each collection face. This eliminates the need for long air ducts and radial blowers, thereby removing the source of friction-related pressure losses while maintaining effective drying performance at each location independently
Solution Approach 2:
The drying system is segmented into multiple independent pivotable fan elements, each serving a specific collection face. This segmentation allows each fan element to operate independently with minimal air duct length, eliminating the cumulative pressure losses that occur in centralized systems with long air ducts serving multiple collection faces
2Productivity
If a separate drying tunnel is installed to dry poultry droppings, then drying is achieved, but the installation complexity and space requirements increase significantly
Solution Approach 1:
The invention merges the drying function with the existing collection device structure by integrating pivotable fan elements directly at the collection faces. This eliminates the need for a separate drying tunnel installation, reducing both installation complexity and space requirements while maintaining effective drying capability
Solution Approach 2:
The pivotable fan elements serve multiple functions: they provide drying air flow, can be adjusted to different angles (45° to 90°) to optimize drying uniformity, and are positioned to work directly with the collection face geometry. This multi-functionality eliminates the need for separate dedicated drying infrastructure
