Description:FIELD OF THE INVENTION
The present invention relates to the field of agricultural machinery and post-harvest processing systems, specifically to harvesting equipment designed for paddy cultivation. More particularly, it pertains to an innovative paddy harvester box that integrates both grain drying and husk–straw separation mechanisms within the harvesting stage. The invention falls within the domain of mechanized harvesting, grain cleaning, and moisture reduction technologies, offering a compact, retrofittable solution that improves efficiency, reduces post-harvest losses, and enhances grain quality by enabling simultaneous drying and impurity separation during paddy harvesting operations.
BACKGROUND OF THE INVENTION
In traditional paddy harvesting systems, the harvested paddy often gets mixed with husk and straw residues inside the harvester box, resulting in impure grain output that requires additional cleaning and drying operations. Furthermore, freshly harvested paddy typically contains high moisture content (around 20–25%), which necessitates separate post-harvest drying using sunlight or mechanical dryers. These processes are time-consuming, labor-intensive, and increase production costs for farmers.
Additionally, delays in drying can lead to grain discoloration, fungal growth, and quality deterioration, affecting both the market value and storage life of the paddy. The lack of an integrated system for on-field drying and clean separation within the harvesting stage limits efficiency and profitability.

The present invention relates to a modified paddy harvester box that integrates drying and husk–straw separation functions directly into the harvesting process. Traditional harvesting systems collect paddy grains mixed with husk and straw residues, requiring additional post-harvest cleaning and drying operations. Freshly harvested paddy also contains high moisture content, typically between 20–25%, which necessitates separate drying using sunlight or mechanical dryers. These processes are time-consuming, labour-intensive, and increase costs for farmers. The proposed invention addresses these challenges by enabling simultaneous drying and impurity separation within the harvester box itself.
The system comprises multiple functional modules working in synchronization. A husk–straw separation module removes husk, straw fragments, and dust from harvested grains using mechanical sieves, airflow channels, and fan-assisted separation. An integrated drying module reduces grain moisture content by approximately 5–7% during harvesting, utilizing controlled airflow and, in certain embodiments, engine exhaust heat or heating elements. An air circulation and heat control module ensures uniform drying by regulating airflow velocity and maintaining safe drying temperatures.
The cleaned and semi-dried grains are collected in a storage module, which facilitates easy unloading or bagging. A control and monitoring module automates and regulates subsystem operations, employing sensors and microcontrollers to monitor temperature, airflow, and moisture levels. Farmers may also manually adjust drying parameters such as fan speed and target moisture levels through a control panel, providing flexibility under varying field conditions.
Additionally, a waste management module handles separated husk and straw residues, which can be repurposed for fodder, biofuel, or composting. The backend processing unit ensures synchronization of drying, separation, and airflow regulation, thereby improving efficiency and reducing post-harvest losses.
Potential embodiments include basic mechanical separation with passive drying, advanced thermal drying with controlled airflow, hybrid cyclone–mesh separation systems, smart monitoring with automation, multi-stage airflow channel designs, and dual-chamber configurations for separate drying and separation.
By integrating drying and separation into the harvesting stage, the invention reduces labour requirements, minimizes post-harvest losses, improves grain quality, and enhances storage life. The compact and retrofittable design allows farmers to upgrade existing harvesters, making the system economically viable and farmer-friendly.
