Engineering Contradiction Analysis
1Area of stationary object
If conventional column dryers with perforated plates are used, then large spaces for air entry are provided, but the grain drying quality deteriorates due to uneven heating and high cracking rates
Solution Approach 1:
The dryer is divided into multiple horizontal levels with grain discharge outlets at different heights, creating segmented zones that allow controlled air circulation and prevent localized overheating. This segmentation enables uniform drying throughout the grain mass while maintaining efficient air entry spaces.
Solution Approach 2:
The invention transitions from vertical air circulation through perforated plates to horizontal air circulation across multiple levels. This dimensional change allows air to enter and circulate more uniformly through the grain mass, improving drying quality while maintaining adequate air entry areas.
2Productivity
If multi-perforated sheets are installed in columns, then air circulation is enabled, but manufacturing costs increase and air backpressure becomes excessively high
Solution Approach 1:
The invention removes the complex multi-perforated sheet structure from the column design. Instead, air circulation is achieved through horizontal channels and openings at different levels, eliminating the need for expensive perforated plates while maintaining effective air flow through the grain mass.
Solution Approach 2:
The invention replaces the perforated plate mechanism with an alternative air circulation system using horizontal channels and level-based openings. This copying approach achieves the same air circulation function through a simpler, less expensive structural configuration.
3Productivity
If high air backpressure is required for drying, then drying effectiveness is improved, but energy consumption increases significantly
Solution Approach 1:
The invention creates a dynamic air circulation pattern where air flows horizontally across multiple levels rather than forcing air through high backpressure. This dynamic circulation approach maintains drying effectiveness while significantly reducing the energy required for air movement.
Solution Approach 2:
The invention utilizes natural convection and controlled air flow patterns to achieve effective drying without high backpressure. By optimizing air circulation through horizontal channels and level-based outlets, the system maintains drying effectiveness with lower energy consumption.
4Productivity
If hot air circulates through compact grain masses, then drying air contact is increased, but condensation of moisture occurs forming harmful muds
Solution Approach 1:
The dryer is segmented into multiple horizontal levels with controlled air circulation at each level. This segmentation prevents excessive heat concentration in any single zone, reducing the risk of condensation while maintaining adequate air-grain contact for effective drying.
Solution Approach 2:
The invention modifies the air circulation parameters by transitioning from vertical to horizontal flow patterns and controlling air temperature distribution across multiple levels. This parameter change prevents localized overheating and condensation while maintaining effective drying contact.

Implementation Method 1
the drying air is previously heated by means of burner systems or heaters in general. In this way, the hot air circulates through the spaces provided for this purpose, between the grain drying columns and it must enter the columns by passing through the holes in the perforated plates that form the walls of the columns, to then pass through the mass of grain and drag with it the moisture contained therein
Implementation Method 2
the hot air circulates through the spaces provided for this purpose, between the grain drying columns and it must enter the columns by passing through the holes in the perforated plates that form the walls of the columns, to then pass through the mass of grain and drag with it the moisture contained therein
Implementation Method 3
the hot air circulates through the spaces provided for this purpose, between the grain drying columns and it must enter the columns by passing through the holes in the perforated plates that form the walls of the columns, to then pass through the mass of grain and drag with it the moisture contained therein
