Problems solved by technology

However, tea leaves are exposed to the air during the processing of existing equipment. During high-temperature processing, organic substances such as chlorophyll and tea polyphenols in tea come into contact with oxygen in the air, and an oxidation reaction occurs, which reduces the quality of tea. affect the quality of the finished product

specific Embodiment 1

[0031] The housing adopts a double-layer structure, which includes an outer layer and an inner layer, the outer layer is arranged outside the inner layer, and a hollow cavity is formed between the outer layer and the inner layer; the heating device includes a steam generator, and the first fixed The shaft includes a nitrogen pipeline and a steam pipeline. One end of the nitrogen pipeline communicates with the space in the casing, the other end of the nitrogen pipeline communicates with the gas storage tank, one end of the steam pipeline communicates with the hollow cavity, and the other end of the steam pipeline communicates with the steam from the steam generator. Oral communication occurs. Using steam heating, the steam temperature is 100 degrees, when the steam enters, the nitrogen is preheated, which can achieve a better green removal effect. At this time, the second fixed shaft includes a nitrogen discharge pipe and a steam discharge pipe, one end of the nitrogen discharg...

specific Embodiment 2

[0034] The heating device includes an electric heating device, the electric heating device includes at least three electric heating wires, and at least three electric heating wires are evenly embedded in the housing in a spiral shape, and the electric heating device also includes a temperature controller, and the temperature controller controls the connection of the at least three electric heating wires Power input. Alternatively, the electric heating device includes at least three electric heating tubes, and the at least three electric heating tubes are arranged in a ring shape in the casing. The electric heating device also includes a temperature controller, and the temperature controller controls the electric energy input terminals connected to the at least three electric heating tubes. It is more convenient to use electric heating to heat the shell.

[0035] A temperature sensor is arranged in the casing, the temperature sensor is connected to a signal processing module, t...

specific Embodiment 3

[0036] The heating device includes a natural gas burner. The natural gas burner is provided with at least one burner, and at least one burner is arranged under the casing. The natural gas burner is provided with a gas regulating switch. The heat generated by natural gas combustion is used to directly heat the casing to ensure the effect of greening. The equipment has a simple structure and is easy to manufacture.

[0037] A temperature sensor is arranged in the casing, the temperature sensor is connected to a signal processing module, the signal processing module is connected to a display device, and the display device is arranged on the bracket. It is convenient for the user to understand the temperature inside the shell, and then the user can control the heated temperature of the shell through the gas regulating switch to achieve a better heating effect.

Abstract

The present invention relates to the field of machinery and particularly relates to a tea leaf enzyme deactivating and drying integrated machine. The nitrogen protected tea leaf enzyme deactivating and drying integrated machine comprises a shell body and a bracket; the bracket comprises a first column and a second column, a first fixing shaft is arranged on an upper part of the first column, a second fixing shaft is arranged on an upper part of the second column, the shell body is connected with the first fixing shaft through a first bearing, and the shell body is connected with the second fixing shaft through a second bearing; the first fixing shaft is a hollow tube, one end of the first fixing shaft communicates with an inside of the shell body, and the other end of a first fixing shaftcommunicates with a gas storage tank; and a heating device for heating the shell body is also arranged on one side of the shell body. Through a design, tea leaves are placed in the sealed shell body and during rotating and heating processes of the shell body, nitrogen continuously enters into the shell body, so that the tea leaves are protected by the nitrogen during processes of high temperature,enzyme deactivating and drying, organic substances of chlorophyll, tea polyphenols, etc. in the tea leaves do not oxidize, and quality of finished products of the tea leaves are ensured.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an integrated machine for fixing and drying tea leaves. Background technique [0002] The greening of tea leaves is to destroy and passivate the oxidase activity in fresh tea leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make the tea leaves soft, easy to knead and form, and at the same time emit green Odor, a tea-making step that promotes the formation of a good aroma. However, tea leaves are exposed to the air during the processing of existing equipment. During high-temperature processing, organic substances such as chlorophyll and tea polyphenols in tea come into contact with oxygen in the air, and an oxidation reaction occurs, which reduces the quality of tea. affect the quality of the finished product. Contents of the invention [0003] The object of the present invention is to provide ...
