Not only that, the hot dryer is also quite energy-consuming and the drying time is also longer.

Not only that, the product also dries very quickly, is versatile and can save energy. The only disadvantage of this grape drying technology is the slightly high investment cost.

The advantage of this technology is that it can keep the nutrition, color, and good quality of raisins. Brings aesthetics to grapes after drying. However, the drying time is long and quite cumbersome, and the cost is also high. This makes many people confused when choosing.
