Food spoilage is one of the critical problems the world is facing today. A majority of food spoilage is happening in the post-harvest period due to inadequate storage and processing facilities. Cold storage is a good option but it is very much expensive and energy intensive.
Hence food drying comes to lime light. Drying is one of the oldest methods used for food preservation. It is method by which the moisture will be removed, thereby restricting microbial and fungal growth. Direct sun drying has some disadvantages like exposure to dust, colour change, pigmentation, insects attack etc.
Use of fossil fuel derived energy for drying has been used for getting good quality products. But fossil fuel usage is too costly and will add up to the energy demand and climate problems. Hence, solar drying is best suited sustainable way for food drying.
- Solar drying preserves the quality of the dried products, including the preservation of their vitamin composition and the inactivation of enzymes and microorganisms
- Solar dryers reduce the drying time significantly compared to traditional drying methods, thanks to the high air temperature within the dryer
- Solar dryers are economically advantageous as they improve the shelf life of the dried products, reduce their density, and lower transportation costs
- Solar dryers are environmentally friendly and clean, making them a sustainable option for drying herbs and spices
- Solar dryers provide an efficient and effective solution for drying herbs and spices, ensuring high-quality products while reducing drying time and costs.
