DESIGN AND FABRICATION OF ELECTRIC/GAS DEHYDRATOR
Abstract
The design and fabrication of a hybrid dehydrator for drying food integrates both gas and
electric heating systems to enhance efficiency, reduce energy consumption, and ensure
consistent drying performance. Traditional dehydrators rely solely on electricity or solar
energy, often leading to high operational costs or weather dependency. This hybrid model
combines a gas-powered heating element for rapid heat generation with an electric heating
system for precise temperature control, optimizing drying conditions for various food types.
The dehydrator features an insulated drying chamber, adjustable trays for uniform airflow,
and a thermostat to maintain optimal temperatures (50–70°C) for moisture removal while
preserving nutritional quality.
Key advantages include reduced drying time, lower energy costs, and adaptability to
fluctuating power supply conditions, making it suitable for small-scale foods and rural
applications. Performance tests indicate a 30% reduction in drying time compared to
conventional electric dehydrators, with improved product shelf life and texture. The hybrid
design also incorporates safety mechanisms such as overheating protection and gas leakage
detectors. This innovation presents a sustainable and cost-effective solution for food
preservation, addressing post-harvest losses in regions with limited access to reliable
electricity
