Constant-temperature and constant-humidity black tea fermentation machine capable of controlling temperature on surfaces of tea leaves

Abstract

The invention provides a constant-temperature and constant-humidity black tea fermentation machine capable of controlling the temperature on the surfaces of tea leaves, and belongs to the technical field of a tea leave fermentation machine. The constant-temperature and constant-humidity black tea fermentation machine comprises a cabinet body, wherein a refrigeration device, a humidification device, a heating device and a temperature and humidity probe are arranged in the cabinet body; the refrigeration device, the humidification device, the heating device and the temperature and humidity probe are connected with a controller; a group of ventilation stainless steel fermentation baskets is arranged in the cabinet body; a leaf temperature probe and an air supply air pipe are inserted in each ventilation stainless steel fermentation basket in a penetrating way; the air supply air pipe is connected with an air supply starting device; the leaf temperature probe and the air supply starting device are connected with the controller. The constant-temperature and constant-humidity black tea fermentation machine capable of controlling the temperature on the surfaces of tea leaves has the advantages that the structure is simple; the design is reasonable; by using the fermentation machine, the temperature and humidity in the cabinet body can be controlled; in addition, the surface temperature of the tea leaves can also be controlled; the goal of precisely controlling the fermentation temperature of the tea leaves can be achieved; the fermentation quality is improved.

Description

technical field [0001] The invention belongs to the technical field of tea fermentation machines, and in particular relates to a constant temperature and humidity black tea fermentation machine capable of controlling the surface temperature of tea leaves. Background technique [0002] Black tea fermentation machine is a necessary black tea fermentation equipment for black tea production enterprises. Although the black tea fermentation machines currently in use on the market can control temperature and humidity in name, they can only increase the temperature and humidity of the air in the fermentation tank, but cannot lower the temperature, nor can they detect and control the leaf temperature of the tea leaves. When the natural room temperature exceeds 30°C for fermentation, the heat generated by the oxidation of tea polyphenols will cause the leaf temperature of the tea to be too high, making the taste of the tea sour and producing an unpleasant smell.
