How to dry fruits without sunlight or a dehydrator?

I need to dry amla (Indian gooseberry). I live in India so we get plenty of sunlight but I live in the city and it's very dusty outside, so I can't leave fruits out, otherwise they'll be covered in dust. But the indoor temperatures are quite warm (around 30 degrees celsius). Can I just dry the fruits (preserved in sugar syrup) indoors or will they spoil? thanks for your help :)
