Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drying cabinets exhibit inhomogeneous air flow patterns, leading to uneven dehydration of products, resulting in prolonged drying times and high energy consumption, as well as issues with residual moisture content in foodstuffs like raw sausage.
Innovation Solution
The introduction of a drying carriage equipped with a fan unit and diffusers, allowing for controlled and even air supply through vertical or horizontal air channels, which can be adjusted for individual product treatment, and equipped with heating/cooling registers and programmable control units to optimize drying conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional drying cabinets use inhomogeneous air flow patterns, then the structure is simple, but the drying uniformity deteriorates and energy consumption increases
Solution Approach 1:
The drying cabinet is divided into multiple drying zones with independent air supply systems. Each zone has its own fan unit and diffuser arrangement, allowing independent control of air flow parameters. This segmentation enables optimized drying uniformity in each zone while maintaining overall system efficiency, resolving the contradiction between drying precision and energy consumption.
Solution Approach 2:
Different regions of the drying cabinet are equipped with locally optimized air supply characteristics. The fan units and diffusers are positioned and configured to create appropriate air flow patterns for specific product arrangements in each zone. This local optimization ensures uniform drying throughout the cabinet without requiring excessive energy input across the entire system.
2Productivity
If conventional drying cabinets use strong air streams in certain zones, then air circulation is improved, but drying uniformity deteriorates due to turbulent flow
Solution Approach 1:
The system employs variable speed fan units that can dynamically adjust air flow rates based on drying stage and product requirements. During initial drying phases, higher speeds provide rapid moisture removal, while later phases use reduced speeds for uniform finishing. This dynamic control reconciles the need for both high productivity and drying uniformity.
Solution Approach 2:
The drying process utilizes periodic cycles of varying air flow intensity. Fan units operate in alternating patterns of high and low speed, creating periodic air flow that prevents turbulence-related non-uniformity while maintaining overall drying efficiency. This periodic action allows the system to achieve both fast drying and uniform results.
