Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for drying raw meat skin in home refrigerators are inefficient, pose food safety risks, occupy space, and present an unappealing sight, with potential for cross-contamination and slow drying times.
Innovation Solution
A modular, powered-fan air box with multiple level support racks that fits inside a refrigerator, utilizing continuous air flow to accelerate the drying process while maintaining meat moisture and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If raw meat is placed on a rack and tray uncovered in a home refrigerator, then the drying process can occur, but cross-contamination risk increases and drying time extends to overnight
Solution Approach 1:
The device segments the drying function from general refrigerator storage by creating a dedicated enclosed air box with controlled air flow paths. The air box is divided into multiple levels with separate air circulation zones, allowing independent control of drying conditions for different meat items without cross-contamination risks.
Solution Approach 2:
A powered fan acts as an intermediary to actively circulate air through the meat items and across heating elements, creating a controlled micro-environment. The fan-driven air flow serves as a mediator between the heating source and the meat surface, enabling efficient heat transfer and moisture evaporation without requiring prolonged exposure to general refrigerator air.
2Reliability
If raw meat is placed on a rack and tray uncovered in a home refrigerator, then drying can occur, but refrigerator space is occupied and meat is exposed to cross-contamination
Solution Approach 1:
The air box is designed to nest within the existing refrigerator space, utilizing vertical and horizontal dimensions efficiently. Multiple levels of racks are nested within the enclosed air box structure, allowing multiple meat items to be dried simultaneously in a compact footprint that fits within standard refrigerator constraints.
Solution Approach 2:
The device creates a localized controlled environment within the air box, providing specific drying conditions (controlled air flow, heat exposure) only where needed for the meat items, while the rest of the refrigerator remains unaffected. This localized approach prevents cross-contamination by isolating the drying zone from other refrigerator contents.
3Ease of operation
If raw meat is placed on a rack and tray uncovered in a home refrigerator, then drying can occur, but the exposed meat presents an unappetizing scene
Solution Approach 1:
The air box incorporates a transparent or translucent front panel that allows visual monitoring of the drying process while maintaining the enclosed protective environment. This flexible barrier provides a window into the drying zone without compromising the sealed nature of the system, allowing users to observe the process without exposing meat to external contaminants or creating unsightly visual exposure.
4Productivity
If a powered-fan air box is used to dry meat, then drying speed increases and cross-contamination is prevented, but device complexity increases
Solution Approach 1:
The air box structure serves multiple functions simultaneously: it provides enclosed containment to prevent cross-contamination, houses the powered fan for active air circulation, incorporates heating elements for moisture evaporation, and includes multi-level racks for versatile meat item placement. This multi-functionality consolidates several drying requirements into a single integrated unit, reducing overall system complexity despite the added features.
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 solution effectively dries raw meat skin quickly and safely, preventing cross-contamination and space occupation, while ensuring a crispy exterior and moist interior when cooked.
Implementation Method 1
The fan draws continuous air flow from one end into the air box and expelling air out the other end of the air box
Implementation Method 2
A heating element may be positioned at the air outlet to assist the drying process
Implementation Method 3
This powered-fan food drying apparatus and method invention helps to remove moisture from the meat food items' skin and surface

AI summary
A modular and configurable powered-fan food drying apparatus with modular front, back and side panels, and modular top and bottom panel. The side panels have multiple levels of ledge support to accommodate multiple configurable food drying position racks. Top and bottom panels have lateral parallel directional air flow channels to direct air flow through the apparatus from back to front. Front panel houses a battery powered-fan that draws air in through the back panel air deflectors into the apparatus cavity and expels air out of apparatus through the front panel powered-fan. The air flows all around the positioned racked food items as it moves in one direction, from back to front and out of the apparatus. The continuous air flowing all around food items speeds up the food surface area drying time.
