- May 07, 2019 -

Carrot has a high nutritional value and a variety of health effects, which contains rich vitamins, sugar, starch, potassium, calcium, phosphorus, iron and other nutrients, inorganic salts and five essential amino acids for human body. Carrot grain is a new type of vegetable processing product which has been raised in domestic and foreign shopping malls in recent years. Because of its rich nutrients, bright color and fresh taste, it is welcomed by vast consumers.

carrot dryer consists of feeder, drying bed, heat exchanger and dehumidifier. When the dryer is working, the cold air is heated through the heat exchanger, and the hot air is circulated through the drying material on the bed surface through a scientific and reasonable circulation mode to exchange heat and mass evenly. The hot air in each unit of the dryer is circulated by the circulating fan, and then the low temperature and high humidity air is discharged to complete the whole drying process smoothly and efficiently. The carrot drying equipment developed by the company has successfully solved the following difficulties: 1. fading, bright color of carrots, loss of water-soluble pigments in the process, resulting in different degrees of fading of products. 2. The shape of carrot is not uniform. Because of the heat and mass transfer during drying process, the internal stress of carrot tissue results in deformation. 3. Flavor weakening, carrot in blanching and drying process, may cause a lot of loss of nutrients and flavor substances, make the product taste rough, light and tasteless. 4. Unqualified packaging materials, the moisture content of carrot slices is very low and easy to absorb moisture, especially when the structure of expanded carrot slices is loose and porous, it is easier to absorb moisture and regain moisture. Characteristics of carrot drying equipment: 1. It can adjust air volume, heating temperature, material residence time and feeding speed to obtain the best drying effect. 2. Most of the air is recycled to save energy. 3. Unique air distributor makes the hot air distribution more uniform and ensures the consistency of product quality. 4. Heat source can be steam, heat conducting oil, electric or coal-fired (oil) hot blast stove. 5. Equipment configuration is flexible, belt washing system and material cooling system can be used.
