Dehumidifying tea

Dehumidifying tea drying is an advanced processing technique that removes moisture from tea leaves under controlled humidity and temperature conditions. This method preserves the delicate aroma, flavor, and bioactive compounds of tea while ensuring uniform drying, making it ideal for producing high-quality green, oolong, white, and black teas.

Dehumidifying tea drying is an advanced processing technique that removes moisture from tea leaves under controlled humidity and temperature conditions. This method preserves the delicate aroma, flavor, and bioactive compounds of tea while ensuring uniform drying, making it ideal for producing high-quality green, oolong, white, and black teas. Unlike traditional sun-drying or hot-air methods, dehumidifying drying minimizes oxidation and microbial growth, resulting in a premium, shelf-stable product.

Production Process
The dehumidifying drying process involves several key stages:

Fresh Leaf Selection: Tea leaves are harvested at optimal maturity and sorted to remove impurities.

Withering: Leaves are spread thinly to allow partial moisture loss and initiate enzymatic reactions.

Dehumidifying Drying:

Climate Control: Leaves are placed in sealed chambers where humidity is reduced to 30–50% using desiccants or heat pump systems, and temperatures are maintained at 25–40°C to avoid thermal degradation.

Airflow Management: Gentle, even airflow ensures consistent drying without damaging leaf structure.

Multi-Stage Drying: Gradual moisture removal in phases (e.g., initial rapid drying followed by slow finishing) preserves polyphenols, catechins, and volatile oils.

Key Benefits

Flavor & Aroma Preservation: Retains terpenes, theanine, and other volatile compounds responsible for tea’s nuanced taste and fragrance.

Nutrient Retention: Protects antioxidants like EGCG (epigallocatechin gallate) and vitamins, enhancing health benefits.

Consistency: Eliminates weather dependency, enabling year-round production with uniform quality.

Extended Shelf Life: Reduces moisture to 3–5%, preventing mold and extending storage life up to 2 years.
