Problems solved by technology

[0002] At present, the greening process of tea leaves requires manual on-site control of the degree of greening, which has the following disadvantages: 1. Professional tea masters are required to check the degree of greening repeatedly at all times. There are many uncertain factors in artificial control and it is difficult to find professional tea masters; 2. It is impossible When the water content of tea is reduced due to high temperature evaporation, the temperature also needs to be reduced accordingly, which often leads to excessive water loss and even scorching of tea leaves; 3. The existing greening process cannot meet the needs of large-scale production

Embodiment 1

[0029] Step 1: start the system, the controller 40 sets the preset parameter curve of tea greening, and transmits it to the recorder 90, and the recorder 90 records the parameter curve of temperature and humidity changing with time and compares it with the preset parameter curve at the same time. The display screen shows that if there is a deviation, the alarm 100 will give an alarm, and the staff will make adjustments according to the alarm;

[0030] Step 2: Fully open the gas control valve 13, preheat the drum 11 to 280°C according to the set temperature according to the tenderness of the green leaves, and the temperature controller 60 and the humidity controller 70 sense the greening machine through the temperature sensor 12 and the humidity sensor 14 The temperature in 10 and the humidity in the drum 11, the temperature controller 60 and the humidity controller 70 feed back the temperature and humidity to the controller 40, and the controller 40 controls the opening and clo...

Embodiment 2

[0035] The control method of the system is as follows,

[0036] Step 1: Start the system, the controller 40 sets the preset parameter curve of tea greening, and transmits it to the recorder 90, and the recorder 90 records the parameter curve of temperature and humidity changing with time and compares it with the preset parameter curve, and displays it Displayed on the screen, if there is a deviation, the alarm 100 will give an alarm, and the staff will adjust according to the alarm;

[0037] Step 2: Fully open the gas control valve 13, preheat the drum 11 to 280°C according to the set temperature according to the tenderness of the green leaves, and the temperature controller 60 and the humidity controller 70 sense the greening machine through the temperature sensor 12 and the humidity sensor 14 The temperature in 10 and the humidity in the drum 11, the temperature controller 60 and the humidity controller 70 feed back the temperature and humidity to the controller 40, and the ...

Embodiment 3

[0042] The control method of the system is as follows,

[0043] Step 1: Start the system, the controller 40 sets the preset parameter curve of tea greening, and transmits it to the recorder 90, and the recorder 90 records the parameter curve of temperature and humidity changing with time and compares it with the preset parameter curve, and displays it Displayed on the screen, if there is a deviation, the alarm 100 will give an alarm, and the staff will adjust according to the alarm;

[0044] Step 2: Fully open the gas control valve 13, preheat the drum 11 to 300°C according to the set temperature according to the tenderness of the green leaves, and the temperature controller 60 and the humidity controller 70 sense the greening machine through the temperature sensor 12 and the humidity sensor 14 The temperature in 10 and the humidity in the drum 11, the temperature controller 60 and the humidity controller 70 feed back the temperature and humidity to the controller 40, and the ...

Abstract

The present invention discloses a tea leaf enzyme deactivating controlling system which includes an enzyme activating machine (10), and also includes a roller (11) rotably arranged in the enzyme activating machine body (10), a temperature sensor (12) arranged in the enzyme activating machine body (10) and a fuel gas control valve (13) arranged at the bottom of the enzyme activating machine body (10). A humidity sensor (14) is arranged within the roller (11). The system also includes an opening and closing controller (50), a temperature controller (60), a humidity controller (70) and a roller controller (80) connecting to a controller (40). The temperature sensor (12) and the fuel gas control valve (13) are respectively connected to the temperature controller (60), and the humidity sensor (14) is connected to the humidity controller (70). The controlling system can realize intelligent control of the enzyme activating process, the tea leaf water loss is just right, and the system can improve productivity and ensure the quality of tea leaves.

Description

technical field [0001] The invention relates to a tea making equipment, in particular to a control system and method for greening of oolong tea leaves. Background technique [0002] At present, the greening process of tea leaves requires manual on-site control of the degree of greening, which has the following disadvantages: 1. Professional tea masters are required to check the degree of greening repeatedly at all times. There are many uncertain factors in artificial control and it is difficult to find professional tea masters; 2. It is impossible When the water content of the tea leaves is reduced due to high temperature evaporation, the temperature also needs to be reduced accordingly, which often leads to excessive water loss and even scorching of the tea leaves; 3. The existing degreening process cannot meet the needs of large-scale production. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a tea gree...
