Preparation of additive-free instant tea particles of one method
2014
The present invention belongs to the technical field of deep processing of tea, instant tea provides a method for preparing particles which does not contain additives, including raw materials extraction, filtration, concentration, sterilization, spray drying granulation, wherein the concentrate obtained by concentration of the concentrate 20 % -50%, the granulation liquid mixing the concentrate with the compressed air, foaming on a foaming machine, tea leaves after foaming concentrate was spray-dried to prepare instant tea granules. The present method of preparing instant tea prepared hollow spherical particles, mainly in the range of 100-500 [mu] in diameter, large particles, and high uniformity of product size, fluidity, good solubility; the manufacturing process does not add any materials, products granulation and drying synchronization is complete, the entire production process is simple, low cost of production, with a strong operability suitable for industrial production.
