Automatic control device for humidity stages during tea withering

Abstract

This invention provides a staged automatic humidity control device for tea withering, comprising a humidity adjustment module, a humidity detector, and an automatic humidity controller. The automatic humidity controller is electrically connected to the humidity adjustment module and the humidity detector. The automatic humidity controller stores at least one humidity adjustment program, which includes a plurality of staged, automatically and continuously set values ​​and an execution duration corresponding to each set value. When the humidity detector detects a humidity value greater than a preset value, the automatic humidity controller activates the humidity adjustment program to drive the humidity adjustment module to sequentially adjust the humidity of the withering environment, maintain the humidity of the withering environment within the execution duration corresponding to each set value, and then automatically switch to the next set value until the humidity adjustment program ends, thereby improving the flexibility of humidity control during the withering process and the consistency of withering quality.

Claims

1. A staged automatic humidity control device for tea withering, comprising: a humidity adjustment module; a humidity detector for detecting humidity in a withering environment and generating a detected humidity value; and an automatic humidity controller electrically connected to the humidity adjustment module and the humidity detector, wherein the automatic humidity controller has at least one humidity adjustment program stored in its memory, the humidity adjustment program including a plurality of staged automatic continuous set values ​​and an execution duration corresponding to each set value, wherein the automatic humidity controller starts the humidity adjustment program when the detected humidity value is greater than a preset value, so as to drive the humidity adjustment module to sequentially adjust the humidity of the withering environment to each set value, and maintain the humidity of the withering environment within the execution duration corresponding to each set value, and automatically switch to the next set value when the execution duration expires, until the humidity adjustment program ends.

2. The automatic control device for the staged humidity control of tea withering as described in claim 1, wherein, These settings are sequentially increased or sequentially decreased, and the execution duration corresponding to the first setting is greater than the execution duration of each subsequent setting.

3. The automatic control device for the staged humidity control of tea withering as described in claim 2, wherein, The difference between two adjacent settings is a relative humidity of 1 to 10%.

4. The automatic control device for the staged humidity control of tea withering as described in claim 3, wherein, The humidity adjustment program consists of three stages, with the corresponding set values ​​set to 60%, 65%, and 70% respectively, and the corresponding execution durations being 6 hours, 3 hours, and 3 hours respectively.

5. The automatic control device for the staged humidity control of tea withering as described in claim 1, wherein, The preset value is 50-60% relative humidity.

6. The automatic control device for the staged humidity control of tea withering as described in claim 1, wherein, The humidity control module includes at least one of a dehumidifier and a humidifier.

7. The automatic control device for staged humidity control of tea withering as described in claim 6, wherein, During the execution of the humidity control program, the humidity detector continuously detects the humidity of the withering environment and generates multiple real-time humidity values. The automatic humidity controller compares the real-time humidity values ​​with the currently executed set value, and adjusts at least one of the dehumidifier and the humidifier according to the comparison result to maintain the humidity of the withering environment.

8. The automatic control device for the staged humidity control of tea withering as described in claim 1, wherein, The automatic humidity controller is a programmable logic controller.

9. The automatic humidity control device for tea withering as described in claim 1 further includes an operation interface electrically connected to the automatic humidity controller, for a user to set or edit the preset value and the number of stages of the humidity adjustment program, the set value of each stage and its corresponding execution duration; and the operation interface displays the set value currently being executed by the humidity adjustment program, the remaining execution duration and the next set value.

10. The automatic control device for the staged humidity control of tea withering as described in claim 9, wherein, The automatic humidity controller is equipped with a memory unit to store multiple humidity adjustment programs, so that the user can select one of the humidity adjustment programs to execute through the operation interface.
