A solar dryer's versatility extends far beyond the conventional. It opens up a new world of possibilities for drying a wide array of products, ushering in sustainability and efficiency. Here are some optimal choices for solar drying:
What produce is best for solar drying
Herbs & Spices: Pepper, cloves, moringa, neem — dry easily and retain their aroma, color, and potency.
Fruits: Mango, papaya, banana, pineapple, dragon fruit — thin slices dry faster, preserving sweetness and reducing spoilage.
Vegetables: Tomatoes, garlic, onions, chili, maize kernels — small, even cuts ensure uniform drying and longer shelf life.
Animal / Livestock Products: Fish fillets, black soldier fly larvae, animal feeds — when handled hygienically, drying reduces moisture and prevents mould
What produce to be cautious with
Very juicy fruits like watermelon — It has long drying times, high spoilage risk.
Thick pieces or whole tubers (e.g. potatoes, cassava) — Causes uneven drying inside.
High fat/oil-rich crops (e.g. oily seeds) — risk of rancidity before fully dry.
Humid or rainy environments — moisture slows on-dryer performance, risk mold.
