Drying apparatus and control method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drying apparatuses often fail to perform optimal drying operations when users select incorrect courses or re-dry materials, leading to potential damage due to excessive drying, as they lack the ability to objectively determine the humidity state of the material and adjust settings accordingly.
Innovation Solution
A drying apparatus equipped with a processor that identifies whether a drying request is initial or additional based on weight and humidity information, and adjusts drying parameters such as temperature, time, and end determination conditions to perform efficient additional drying operations without damaging the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drying apparatus performs the same drying operation without reflecting previous drying history, then the operation is simple, but the material to be dried is damaged due to excessive drying
Solution Approach 1:
The processor receives drying history information from the receiver and uses this feedback to adjust the drying operation. The system monitors whether the material has been dried and modifies subsequent drying parameters accordingly, preventing excessive drying while maintaining system reliability.
Solution Approach 2:
The system performs preliminary identification of the drying state by receiving and processing drying history information before executing the drying operation. This preliminary action allows the system to prepare appropriate drying parameters in advance, avoiding material damage.
2Measurement precision
If the user changes the drying setting directly, then the user has control, but the user may not objectively determine the humidity state of the material to be dried
Solution Approach 1:
The drying apparatus performs self-diagnosis by automatically receiving and analyzing drying history information to determine the current drying state of the material. This eliminates the need for users to manually assess humidity conditions, providing precise measurement while maintaining ease of operation.
Solution Approach 2:
The system replaces manual user judgment with an automated electronic detection mechanism. The processor objectively determines the humidity state by processing drying history data, substituting the mechanical action of user assessment with an automated sensing and analysis system.
3Adaptability or versatility
If the drying apparatus provides various drying courses, then the functionality is enhanced, but the user may select a wrong course
Solution Approach 1:
The system uses drying history information as feedback to automatically determine the appropriate drying course. Instead of relying on user selection alone, the processor analyzes the received drying history data and selects or adjusts the drying course accordingly, reducing selection errors while maintaining diverse drying options.
4Productivity
If the drying apparatus performs additional drying operation based on previous drying request, then the drying efficiency is improved, but the drying parameters may cause material damage
Solution Approach 1:
The drying parameters are made dynamic rather than static. The processor adjusts drying parameters based on the received drying history information, allowing the system to adapt the drying intensity and duration to the actual material state, thereby improving efficiency while preventing damage.
Solution Approach 2:
The system changes drying parameters (such as temperature, time, or intensity) based on the analysis of drying history information. By modifying these parameters according to the material's current state, the system achieves efficient additional drying without causing material damage.

AI summary
A drying apparatus including a drying unit and a processor configured to control an operation of the drying unit. The processor is configured to, based on a drying request being received, identify whether the drying request is an initial drying command for a material to be dried or an additional drying request for the material to be dried, and based on the drying request being identified as the additional drying command, control the drying unit to perform an additional drying operation for the material to be dried based on a drying operation method corresponding to a previous drying command for the material to be dried.
