spray drying equipment

Application of spray drying equipment - There are generally three ways to drink tea: First, brew refined dry tea with hot water and drink slowly. This method still dominates in my country. Second, the tea leaves are extracted and mixed into canned tea water, which can be drunk as soon as the lid is opened. Third, the effective ingredients of tea leaves are extracted, concentrated and dried to make instant tea powder, which can be brewed and drunk immediately, meeting the needs of people's modern high-efficiency and fast-paced life. Process flow of tea spray drying: 1. Dry green tea crushing Use a grinder to crush the tea leaves to obtain 40-mesh tea powder for standby use. 2. Extraction Take a certain amount of tea powder, then add 0.5% β-cyclodextrin and 0.025% EDTA to prevent the loss of effective ingredients. ^ Then add a proportion of distilled water and extract at a certain temperature and time. 3. Vacuum concentration The extract is filtered with filter cloth, and then condensed, and vacuum concentrated at a vacuum degree of 0.95 MPa to concentrate to a dry matter content of about 20%. 4. Spray drying: Homogenize in a homogenizer to form an emulsion. Spray drying is performed at an air inlet temperature of 200-220°C and an air outlet temperature of 85-90°C.
