Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] A kind of tea alkali reduction cover device is made of stainless steel, and is equipped with the tea drying bucket (15) that upper edge is round, upper edge is smooth, and the diameter of the drying bucket upper edge (14) is 48cm.

[0024] The tea alkali reduction cover device comprises two parts, an inner shell (6) and an outer shell (5). The inner shell (6) is shaped like a circular platform with upper and lower openings, double-layer structure, the middle of the double-layer structure is filled with aluminum silicate fiber cotton and sealed, the thickness of the inner shell aluminum silicate fiber cotton layer (9) is 3cm, and the upper end of the circular platform is open (1) The diameter is 10cm, and the diameter of the opening (13) at the lower end of the round table is 52cm; the shell (5) is shaped into a bottomless cone with a double-layer structure, an...

Abstract

The invention discloses an alkali-reducing cover device of tea, wherein the device is used with a tea drying bucket; after caffeine in the tea is sublimated by an inner and outer double-layer structure, the caffeine does not condense and fall, and is discharged from the drying bucket with hot air. The alkali-reducing cover device is designed to quickly assemble and disassemble with the drying bucket. With the adoption of the device, caffeine content in the tea can be effectively reduced and the tea quality is improved.

Description

technical field [0001] The invention relates to a tea alkali-reducing cover device and a using method thereof, belonging to the technical field of tea processing. Background technique [0002] Low-caffeine tea is a new type of tea suitable for specific groups of people who are sensitive to caffeine, such as neurasthenia, pregnant women, the elderly, and children. When the tea leaves are processed with a tea baking device, the caffeine in the tea leaves will sublimate at high temperature and enter the air above the drying bucket, and will condense and fall back into the tea leaves due to the decrease of the external air temperature, making the caffeine content in the tea leaves always high. And existing tea caffeine reduction technique comprises hot water extraction method, organic solvent extraction method, supercritical CO 2 Extraction methods, chromatographic adsorption methods, etc., are not suitable for normal tea processing enterprises because they cannot guarantee the...
