High Quality Freeze Dryer For Tea

2.1 influence of vacuum freeze drying on the quality of Oolong tea

2.1. 1 water content of tea sample

The results showed that the water content of dried tea was 3.7%, that of frozen tea was 28.0%, and that of freeze-dried tea was 2.0%. Through vacuum freeze-drying, the moisture content is low, which is conducive to the long-term storage of tea.

3 discussion

(1) In the process of thermal drying, dried tea causes the loss of some aroma components and the oxidation of heat-sensitive substances. The aroma and taste of tea are greatly affected, and the content of aroma components is significantly lower than that of freeze-dried tea and frozen tea.

(2) Frozen tea is stored directly without the drying process, which basically retains the original aroma components in the processing process, showing a strong aroma and strong flower fragrance. The water content of frozen tea is generally higher than 20%, the requirements for storage and transportation conditions are high, and it is not conducive to long-term storage. The contained components are easy to oxidize and deteriorate, thus affecting the taste and soup color, showing that the taste is still mellow and the soup color is not bright. These shortcomings are an important reason why frozen tea can not expand the sales market.

(3) Freeze-dried tea has the advantages of less than 3% water content, complete dehydration, easy long-term storage, convenient transportation, and sales. Freeze-dried tea has the advantages of cold frozen tea and dried tea, and makes up for their shortcomings. It has a broad application prospect.
