Heated Roller Soil Detachment for Root Vegetable Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for cleaning root vegetables, particularly those with sticky soil, often experience rotational blockages and ineffective soil removal due to accumulated soil on and between rollers, especially in wet and clayey conditions, leading to malfunction and potential breakage.
Innovation Solution
A device with rollers equipped with a heating means to dry the soil stuck on their outer walls, ensuring soil detachment and prevention of clogging, utilizing a heat transfer fluid or hot air circulation to maintain a temperature that makes the soil crisp and non-sticky, allowing for continuous operation and effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rollers are used to clean root vegetables, then soil removal efficiency is improved, but sticky soil accumulates on and between rollers causing blockages
Solution Approach 1:
The patent applies thermal energy to change the physical state of sticky soil from wet/adhesive to dry/crisp, preventing accumulation on rollers. By heating the roller surface, the soil's adhesion properties are fundamentally altered, allowing continuous operation without blockages.
Solution Approach 2:
The patent converts the harmful effect of sticky soil accumulation into a beneficial drying process. The heat applied to remove soil stickiness also serves to dry the vegetables, turning a problematic condition into a useful function.
2Reliability
If heating means is added to rollers, then soil detachment is improved, but device complexity increases
Solution Approach 1:
The patent uses a fluid circulation system (hydraulic principle) to transfer heat to the rollers. A heating fluid circulates through channels in the roller, providing thermal energy without requiring direct flame or complex heating elements on the roller surface.
Solution Approach 2:
The patent introduces a heating fluid as an intermediary substance to transfer thermal energy to the rollers. This mediator allows heat transfer without direct contact between the heat source and the roller, simplifying the overall system design.
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 heating mechanism effectively dries and detaches sticky soil from the rollers, preventing blockages and ensuring efficient soil removal from root vegetables, even in adverse conditions, thereby maintaining the functionality of the cleaning device and ensuring clean vegetables.
Implementation Method 1
at least one of the rollers is equipped with a means for heating its outer wall. Thus, with the outer wall of the roller being heated, this has the effect of drying the soil that may be stuck on the roller
Implementation Method 2
The vibrations due to the displacement of the vegetables on the rollers ensure that the soil thus dried is detached and cause it to fall to the ground
Data Source
AI summary
A device for cleaning root vegetables include at least two rollers each rotatably mounted about an axis perpendicular to a direction of travel of the root vegetables on the rollers. At least one of the rollers is equipped with a means for heating its outer wall. Thus, with the outer wall of the roller being heated, this has the effect of drying soil that is possibly stuck thereon. This drying is enough to make the soil crisp and to overcome the suction phenomenon of wet soil on the roller and on reliefs of the roller. Vibrations due to the displacement of the root vegetables on the rollers ensure that the dried soil is detached and falls to the ground.
