So when you only ask about buying a fruit dryer, you obviously think simply that a fruit dryer will has a normal price.

3 Drying methods below are common and most of us only need to use 1 of these 3 drying methods to ensure that we can meet the usage needs in production, including hot drying, heat pump drying and freeze drying.

1. The circulating hot drying method consists of hot air dryer and industrial dryer, which is used for drying common products at high temperatures from 50°C to 100°C or higher, up to 200°C and 300°C depending on the each type of product in civil or industrial. The hot drying method is suitable for drying common and affordable products such as soft dried fruit, dried vegetables, dried fish, dried meat, dried bamboo shoots, dried herbs…

2. Heat pump dryer is used for drying thin, sliced, easy-to-dry products and drying at low temperature of 15 ~ 50 degrees Celsius such as thinly sliced fruits, fruit detox tea, sliced vegetables, dried leaves, starch, flower tea, and many other products…ensure dried products have quality higher than heat drying.

3. The third drying method is currently used less than the above two methods, but in the future it will certainly be very popular, that is, using a freeze dryer. The general characteristics of freeze-dried products are dry, brittle, porous, and retain their natural shape and color. At the same time, the preservation of nutrition is also better than hot and cold drying. Therefore, when you want to make many kind of powders from fruits, vegetables, fish, meat, etc., the freeze-dried product is much easier to grind.
