Working Principle

The Solar Dehydrator relies on a closed-loop solar-thermal cycle. Solar panels or integrated collectors absorb solar energy and convert it into heat. A blower then draws in ambient air, which passes through the heated system and circulates over the food trays. Adjustable vents enable the exhaust of moist air through natural or fan-assisted means. Meanwhile, a PID temperature controller maintains ideal drying conditions, usually between 40°C and 75°C. This process efficiently removes moisture, preventing microbial growth and preserving the integrity of the food.

Features

Food-grade Safety: 

Made from stainless steel and BPA-free materials, it complies with international food safety standards such as HACCP and FDA.

Energy Efficiency:

By utilizing solar power, it cuts down electricity or gas consumption by 60%–90%, and there are backup options available for overcast days.

Uniform Drying:

The forced convection combined with the multi-layer tray design ensures even air distribution, reducing drying time by 30%–50% compared to traditional sun-drying.

Modular Scalability:

It comes in capacities ranging from 0.5 to 10+ tons per day, and can be customized for farms, small and medium-sized enterprises, or large-scale factories.

Easy Maintenance:

The removable trays and smooth surfaces make cleaning quick and easy, which is crucial for meeting HACCP requirements.

Technical Highlights

Solar Thermal Conversion:

It uses high-efficiency monocrystalline silicon cells or evacuated tube collectors to maximize the capture of solar energy.

Intelligent Control:

PID algorithms and optional IoT-enabled monitoring allow for remote adjustment of temperature and humidity, as well as data tracking.

Insulation & Retention:

High-density insulation materials minimize heat loss, ensuring stable temperatures even in cool climates.

Forced Convection:

Centrifugal blowers create a uniform airflow, ensuring consistent drying across all tray levels.

Application Fields

It is well-suited for commercial processing of the following:

Fruits like mangoes, bananas, papayas, and apples

Vegetables such as carrots, spinach, mushrooms, and peas

Meat and seafood products including jerky, fish fillets, and shrimp

Herbs and spices like basil, turmeric, and cinnamon

Medicinal herbs such as ginseng and goji berries
This equipment is ideal for agro-processing centers, farmers' cooperatives, food manufacturing plants, and R&D facilities in universities. It helps cut down post-harvest losses, extend shelf life, and boost product value, all while supporting the goals of sustainable agriculture.
