Embodiment Construction

[0032] In order to introduce the present invention in more detail, the present invention will be further described with reference to the accompanying drawings.

[0033] A method for drying tea leaves, which is characterized by comprising the following steps:

[0034] 1) Heating and drying, drying the tea at high temperature to remove more water in the tea, and to a certain extent achieve a preliminary sterilization effect on the tea, the drying temperature is 100~150℃, and the drying time is 5~15 minutes, under this condition, can make the moisture in the tea ≤30%;

[0035] 2) Primary cooling. The tea obtained from the first high-temperature drying process is continuously heated and dried at medium and high temperatures, so that there will be no quality changes due to excessive temperature differences, and the remaining part of the moisture in the tea will be further dried. The duration of this process is 10-15 minutes, and the temperature is 60-80℃; it can make the moisture in the ...

Abstract

The invention discloses a method and equipment used for circulation drying of tea. The method comprises following steps: heating and drying, first grade cooling, second grade cooling, third grade cooling, and material discharging. The equipment comprises a circulation drying oven, and a multistage cooling and transporting mechanism; the circulation drying oven comprises a material charging and transporting device, a turning transporting device, a material discharging and transporting device, oven walls, air exhaust openings and a heating device; the material charging and transporting device is arranged at the internal top layer of the circulation drying oven; the turning transporting device is arranged at the internal middle layer of the circulation drying over; the material discharging and transporting device is arranged at the internal bottom layer of the circulation drying oven; one outer side of the circulation drying oven is provided with the heating device; and the multistage cooling and transporting mechanism is formed by a plurality of transporting mechanisms used for drying and cooling at different temperatures. Tea processed by the equipment possesses a certain degree of flexibility, is not fragile, and is suitable for direct soaking or further processing; and broken ratio of tea is reduced, and quality is improved.

Description

Technical field [0001] The invention relates to the shaping and production of scented tea, and in particular to a method and equipment for circularly drying tea leaves.
