 There are four configurations: normal type, gland type, multi-manifold common type, multi-manifold gland with pre-freezing function

Application of freeze dryer in freeze-dried vegetables

    Pumpkin is rich in nutrients and has high medicinal value. It has various health effects such as lowering blood sugar, lowering blood fat, preventing cardiovascular disease, preventing cancer and cancer, detoxifying and deworming, delaying aging and losing weight. Pumpkin has good processing adaptability, and pumpkin powder is one of the products.

    The pumpkin is dehydrated and made into powder, which is not only convenient for storage and transportation, but also has a nutritional value due to the concentration of dry matter. Fan Mingyue and other methods use dry air drying, vacuum drying, vacuum freeze drying to dry the pumpkin, superfine pulverization, study the physicochemical properties and antioxidant activity of pumpkin powder

    The experimental results show that the vacuum freeze-drying has the highest solubility, water holding capacity and oil holding capacity, but the fluidity and bulk density are the smallest. It has good physicochemical properties and can retain the activity of antioxidants well. The nutritional quality of vacuum freeze-dried pumpkin powder is higher than that of hot air dried and vacuum dried pumpkin ultrafine powder.
