Design and develop a smart, solar-powered drying and compact packaging system to support home-based agarbatti manufacturing by rural women artisans.
“Rural women making agarbattis face issues with traditional drying methods, leading to poor quality and income. We need to build an affordable, solar-powered machine that dries agarbattis evenly and hygienically, and also helps package them to keep their fragrance and extend shelf life.”
Deconstructed Problem Blueprint
WHAT TO BUILD?
A compact, low-cost, solar-powered smart drying chamber with temperature and humidity control, integrated with a simple, low-cost packaging/sealing device, specifically designed for home-based agarbatti manufacturing by rural women artisans.
WHO IS IT FOR?
Primary beneficiaries are rural women artisans engaged in home-based agarbatti manufacturing. The Ministry of MSME is the sponsoring organization, aiming to improve livelihoods and product quality.
WHY DOES IT EXIST?
Traditional agarbatti drying is weather-dependent, causing uneven drying, moisture issues, fungal growth, fragrance loss, and breakage. This reduces product quality, shelf life, and ultimately, the income of rural women. There's a lack of affordable, suitable technology for this specific need.
INPUT → PROCESS → OUTPUT ARCHITECTURE PIPELINE
Temperature sensor data (e.g., DHT11/DHT22), Humidity sensor data (e.g., DHT11/DHT22), Solar panel voltage/current data, User inputs (e.g., desired drying time/mode via buttons or simple display), Battery charge level.
Microcontroller-based control logic (e.g., PID for temperature/humidity), Data logging for environmental conditions, Solar charge controller management, Fan speed control for uniform airflow, Heater activation (if passive solar isn't enough), Battery management, Optional IoT data transmission to cloud for monitoring/alerts.
Actuation of fans (ON/OFF, speed control), Actuation of heating elements (if any), Status display on LCD/LED (temperature, humidity, battery level, drying progress), Low battery alerts (visual/audio/optional SMS/app notification), Drying cycle completion alerts, Sealed agarbatti packages.
CONSTRAINTS
- Low-cost (affordable for rural households/SHGs)
- Solar-powered with battery backup (reliable in off-grid/unstable power areas)
- Compact and portable design (suitable for home use, easy to move)
- Easy to operate and maintain (user-friendly for rural women artisans)
- Hygienic and enclosed drying chamber (prevents contamination)
- Ensures uniform drying and fragrance preservation
- Moisture-resistant and aroma-preserving packaging
- Eco-friendly packaging options
- Robustness against varying weather conditions.
JURY METRICS
- Cost-per-unit of the system (target < ₹10,000-15,000)
- Drying uniformity index (e.g., % moisture variation across batch)
- Fragrance retention rate (compared to traditional methods)
- Energy efficiency (agarbatti dried per Watt-hour)
- Shelf life improvement (days/weeks)
- Ease of use (e.g., number of steps, training time)
- Portability (weight, dimensions)
- Battery backup duration (hours of operation without sun)
- Packaging seal integrity and aroma preservation effectiveness.
CORE BOTTLENECK
The single hardest challenge is achieving precise, uniform temperature and humidity control within a low-cost, solar-powered, compact system, especially ensuring consistent airflow and fragrance preservation, while also integrating a practical, affordable packaging solution suitable for rural home-based operations.

Agarbatti making is a key home-based livelihood for rural women, but traditional drying methods depend on weather and often cause uneven drying, moisture issues, and loss of fragrance, reducing product quality and income. Hence, there is a need for an affordable smart drying and packaging system suitable for rural household-based production.
Traditional agarbatti drying is slow, weather-dependent, and leads to uneven drying, fragrance loss, fungal growth, and breakage, reducing product quality and income for rural women artisans.
Therefore, there is a need for a smart solar-powered drying chamber with temperature and humidity control for uniform, hygienic, all-weather drying, along with a low-cost packaging system to preserve fragrance, improve shelf life, and enhance marketability.
The proposed solution is a compact, low-cost, solar-powered smart drying chamber for rural home-based agarbatti production, along with a simple packaging/sealing device to ensure moisture resistance, fragrance preservation, and improved product quality and shelf life.
The system should include:
