尼日利亚采购需求：太阳能食物干燥机、太阳能干燥机、太阳能烘干机、太阳能脱水机

I'm looking for a reliable dryer for vegetables, specifically tomatoes and okra chili pepper. The consistent issue we're facing in Nigeria is electricity supply, so I need a solution that can operate efficiently using either solar power, electricity, or both. Could you provide me with information on models that can accommodate these requirements? It's crucial that the dryer is energy-efficient and suitable for our local conditions. Any additional features or specifications that enhance performance would also be appreciated.
