Composite tea powder drying agent and preparation method thereof

The invention discloses a composite tea powder drying agent. The drying agent is prepared from the following raw materials in parts by weight: 10 to 30 parts of anhydrous calcium chloride, 2 to 20 parts of expanded perlite and 20 to 40 parts of tea leaves. The preparation method comprises the following steps: a, crushing tea leaves until the tea leaves pass through a 60-100-mesh sieve to obtain aproduct A; b, drying the product A to obtain a product B; c, sieving the expanded perlite with a 5-20-mesh sieve, and taking the oversize expanded perlite to obtain a product C; d, drying the productC to obtain a product D; and e, mixing the product B, the product D and anhydrous calcium chloride to obtain a finished product. The drying agent of the invention has the effects of dehumidification and formaldehyde removal, is safe, non-toxic, low in price and good in water retention, and based on the synergistic effect of the tea powder and the anhydrous calcium chloride, the moisture absorptionrate can exceed that of a
