Description

Technical Field

[0001] The invention relates to the technical field of tea processing, and more specifically, to a method for stripping tea blocks. The invention also discloses a device for implementing the stripping method. Background Art

[0002] Liubao tea belongs to the category of dark tea. It uses fresh leaves of group species in Cangwu County, Wuzhou City, large and medium-leaf species in Guangxi, and their separated, selected varieties and strains of tea trees as raw materials, and is processed according to a specific process to produce dark tea with unique quality characteristics. After being autoclaved, Liubao tea is obtained as finished Liubao tea. These finished Liubao teas need to be placed in an aging warehouse for aging for a period of time, so that the contents in the tea leaves undergo a series of biochemical reactions such as oxidation, polymerization, and decomposition under the action of oxygen, microorganisms, and active enzymes in the tea leaves, so that their material composition and content are significantly changed, thereby changing the taste and efficacy of Liubao tea to ensure its quality. As the aging time of finished Liubao tea increases, its quality becomes better. Therefore, many merchants or collectors will store finished Liubao tea for several years, more than ten years, or even more than twenty or thirty years. The value of these finished Liubao teas that have been aged for a long time is also very high.

[0003] However, since Liubao tea is mostly pressed into tea bricks or placed in tea baskets for storage during the preparation process, after a long period of aging, the connection between these tea leaves becomes very tight, and usually a large hard tea block is formed according to the shape of its placement. Nowadays, the peeling of these large hard tea blocks is usually just pried open from the outside to the inside point by point by an experienced master with tools, but such direct prying is easy to break the tea leaves, affecting its appearance, reducing the appearance quality of the tea leaves, and also spending a lot of manpower. There is no processing method for effectively peeling large hard tea blocks by non-manpower methods at present, which greatly increases the processing cost of tea leaves, and it is also difficult to reduce the impact on the quality of tea blocks during the peeling process. Therefore, it is urgent to design a method that can effectively peel large hard tea blocks by non-manpower methods to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a method for peeling tea blocks. The method utilizes the expansion of the volume of solid or liquid dry ice when it sublimates into carbon dioxide gas, so as to achieve the effect of loosening and peeling off the hard tea blocks on the surface. Repeating this process can gradually peel off the large hard tea blocks from the outside to the inside. The method has the characteristics of high peeling efficiency, good quality of the obtained tea leaves, and low labor cost.

[0005] Another object of the present invention is to provide a device for stripping tea blocks, wherein large hard tea blocks can be gradually stripped into dispersed tea leaves, thereby maintaining their quality.

[0006] The first technical solution adopted by the present invention is as follows:

[0007] A method for stripping tea blocks is to repeatedly inject dry ice into a stripping chamber containing large hard tea blocks, and after the dry ice in the stripping chamber is completely sublimated into carbon dioxide, the carbon dioxide is discharged from the stripping chamber to obtain dispersed tea leaves.

[0008] Further, the following steps are included:

[0014] S2.2, the controller controls the position sensor to open and receives the signal from the position sensor in real time. When the controller receives the signal from the position sensor, it controls the first solenoid valve connected to the dry ice injection port to close, stops injecting dry ice into the stripping bin, and controls a pair of motors to rotate synchronously in opposite directions to reset the stripping bin;

[0015] S2.3, let it stand still, and the controller controls the ultrasonic transducer to emit sound waves into the stripping chamber.

[0016] Furthermore, the step S3 comprises the following steps:

The controller obtains the pressure data of the pressure sensor in real time and determines the pressure state in the stripping chamber. When the real-time pressure remains unchanged, it is considered that the dry ice is completely sublimated into carbon dioxide.

[0018] S3.2, the controller controls the second solenoid valve connected to the carbon dioxide exhaust port to open, so as to exhaust the carbon dioxide in the stripping chamber;

[0019] S3.3, the controller obtains the pressure data of the pressure sensor in real time and determines the pressure state in the stripping chamber. When the real-time pressure data remains unchanged, it is considered that the carbon dioxide has been exhausted. The controller controls the second solenoid valve connected to the carbon dioxide exhaust port to close, and repeats step S2 until the large hard tea blocks are completely stripped to obtain dispersed tea leaves.

[0020] Furthermore, in the steps S3.1 and S3.3, the controller determines the pressure state in the stripping chamber by the following steps:

[0021] S0.1, set and initialize the two variables of front pressure value and time value, and set the two constants of pressure range difference and time difference;

[0022] S0.2, the controller periodically obtains the real-time pressure value of the stripping chamber, compares the real-time pressure value with the previous pressure value, and if the absolute value of the difference between the real-time pressure value and the previous pressure value is less than the pressure range difference, the time value is increased by 1;

[0023] S0.3. Set the previous pressure value as the real-time pressure value, compare the time value with the time difference value, if the time difference value is less than the time difference value, repeat step 2, otherwise it is considered that the real-time pressure data remains unchanged.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods, but does not constitute any limitation to the present invention.

[0040] Reference Figure 1 As shown, a method for peeling tea blocks of the present invention is to repeatedly inject dry ice into a peeling bin 1 in which a large hard tea block is placed, and after the dry ice in the peeling bin 1 is completely sublimated into carbon dioxide, the carbon dioxide is discharged from the peeling bin 1 to obtain dispersed tea leaves. The method of the present invention penetrates solid or liquid dry ice into the surface tea leaves of the large hard tea blocks, and its volume expands when it sublimates into carbon dioxide gas, so as to achieve the effect of loosening and peeling the hard tea blocks on the surface. By repeating this process, the large hard tea blocks can be gradually peeled from the outside to the inside, and the peeling efficiency is high. Compared with direct manual prying, the tea leaves peeled in this way can maintain the integrity of the tea leaves' appearance to a greater extent, so that the quality of the peeled tea leaves is well maintained, and labor costs can also be saved.

[0041] Further, the following steps are included:

[0042] S1. Put the big hard tea block into the stripping chamber 1 and cover the chamber cover 2 tightly, so that a closed space can be formed outside the big hard tea block, so that when the solid or liquid dry ice sublimates into carbon dioxide, the pressure of the stripping chamber 1 can be changed, so that the stripping effect is better.

[0043] S2, injecting dry ice into the stripping chamber 1, and performing ultrasonic vibration after standing still.

[0044] Furthermore, the step S2 comprises the following steps:

[0045] S2.1, the controller 14 controls the first electromagnetic valve 4 connected to the dry ice injection port 3 to open, injects dry ice into the stripping chamber 1, controls the pair of motors 13 to rotate synchronously and reversely periodically, and changes the rotation direction of the pair of motors 13 at the same time when the period changes. During the process of injecting dry ice into the stripping chamber 1, the pair of motors 13 rotate synchronously and reversely periodically, so that the stripping chamber 1 can be tilted to the front or rear side, which helps the dry ice to better penetrate into the interior from the surface of the large hard tea block, and when it sublimates into carbon dioxide, as its volume expands, it can loosen more tea leaves.

[0046] S2.2, the controller 14 controls the position sensor 19 to open and receives the signal sent by the position sensor 19 in real time. When the controller 14 receives the signal sent by the position sensor 19, it controls the first solenoid valve 4 connected to the dry ice injection port 3 to close, stops injecting dry ice into the stripping chamber 1, and controls the pair of motors 13 to rotate synchronously in opposite directions to reset the stripping chamber 1. The controller 14 can control the operation of injecting dry ice into the stripping chamber 1 by controlling the opening and closing of the first solenoid valve 4.

[0047] S2.3, let it stand, the controller 14 controls the ultrasonic transducer 7 to work and emit sound waves into the stripping chamber 1, with the assistance of ultrasonic waves, it can further help the dry ice to penetrate from the surface of the large hard tea block into the interior.

[0048] S3, heating the stripping chamber 1 with microwaves, and after the dry ice in the stripping chamber 1 is completely sublimated into carbon dioxide, discharging the carbon dioxide in the stripping chamber 1 from the container, and repeating step S2 until the large hard tea blocks are completely stripped to obtain dispersed tea leaves.

[0049] Furthermore, the step S3 comprises the following steps:

[0050] S3.1, the controller 14 controls the microwave generator 8 to start working. The controller 14 obtains the pressure data of the pressure sensor 9 in real time and determines the pressure state in the stripping chamber 1. When the real-time pressure remains unchanged, it is considered that the dry ice is completely sublimated into carbon dioxide. The dry ice in the stripping chamber 1 is heated by the microwave generator 8 and sublimated into carbon dioxide. This is a process of changing from solid or liquid to gas. Its volume will expand, causing the pressure in the stripping chamber 1 to gradually increase. When all the dry ice in the stripping chamber 1 is sublimated into carbon dioxide, the pressure in the stripping chamber 1 will not change. Therefore, we can judge whether the dry ice has been completely sublimated based on the continuously obtained pressure data of the stripping chamber 1. When it is detected that the pressure of the stripping chamber 1 does not change within a certain period of time, it is considered that the dry ice is completely sublimated into carbon dioxide.

[0051] S3.2, the controller 14 controls the second solenoid valve 6 connected to the carbon dioxide exhaust port 5 to open, so as to exhaust the carbon dioxide in the stripping chamber 1.

[0052] S3.3, the controller 14 obtains the pressure data of the pressure sensor 9 in real time and determines the pressure state in the stripping chamber 1. When the real-time pressure data remains unchanged, it is considered that the carbon dioxide has been exhausted. The controller 14 controls the second electromagnetic valve 6 connected to the carbon dioxide exhaust port 5 to close, and repeats step S2 until the large hard tea block is completely peeled off to obtain dispersed tea leaves. When the pressure in the stripping chamber 1 is greater than the external pressure, the second electromagnetic valve 6 connected to the carbon dioxide exhaust port 5 is opened to discharge the carbon dioxide in the stripping chamber 1. As the carbon dioxide in the stripping chamber 1 is gradually discharged, its pressure will gradually decrease and eventually equal the external pressure. At this time, the gas will no longer flow out, and the pressure in the stripping chamber 1 will no longer change, which means that the carbon dioxide has been exhausted.

[0053] Furthermore, in the above-mentioned step S3.1 and step S3.3, the controller 14 determines the pressure state in the stripping chamber 1 by the following steps:

[0054] S0.1. Set and initialize the two variables of front pressure value and time value, and set the two constants of pressure range difference and time difference. The front pressure value is used to store the pressure value of the previous cycle of stripping chamber 1, and is used to compare it with the pressure value of the real-time cycle. The time value accumulates the number of time periods of pressure maintenance to determine whether the pressure maintenance time reaches the set time difference. The pressure range difference and time difference are constants set according to actual conditions. The pressure range difference indicates that there is no change when it remains within this range. The time difference is used as a time change threshold, indicating that the pressure can remain basically unchanged within this time period, and the pressure is considered stable.

[0055] S0.2, the controller 14 periodically obtains the real-time pressure value of the stripping chamber 1, compares the real-time pressure value with the previous pressure value, and if the absolute value of the difference between the real-time pressure value and the previous pressure value is less than the pressure range difference, the time value is added by 1. The time value starts to accumulate only when the pressure value of the stripping chamber 1 in the real-time cycle is basically the same as the pressure value of the previous cycle, otherwise it does not accumulate.

[0056] S0.3, set the previous pressure value as the real-time pressure value, compare the time value with the time difference value, if the time difference value is less than the time difference value, repeat step 2, otherwise it is deemed that the real-time pressure data remains unchanged. After each comparison between the pressure value of the previous cycle and the real-time cycle pressure value, the real-time cycle pressure value needs to be stored in the previous pressure value to replace the pressure value of the previous cycle, so as to keep the value stored in the previous pressure value as the pressure value of the most recent cycle, so that each pressure value comparison is a comparison between the pressure value of the previous cycle of stripping chamber 1 and the real-time cycle pressure value, so as to ensure the effectiveness of the comparison.

[0057] Furthermore, the method further comprises step S4, pouring the obtained dispersed tea leaves out of the stripping bin.

[0058] The specific steps are as follows: the controller 14 controls a pair of motors 13 to rotate synchronously in opposite directions, so that the stripping chamber 1 rotates in the direction of opening the chamber cover 2 until the top of the stripping chamber 1 tilts downward, and the tea leaves are poured out from the stripping chamber 1, making it more convenient to pour out the tea leaves and increasing the work efficiency.

[0059] Reference Figures 2 to 4As shown, a device for peeling tea blocks of the present invention comprises a peeling chamber 1 and a chamber cover 2, wherein the chamber cover 2 is hinged to one side of the peeling chamber 1, a buckle and a supporting structure for supporting the chamber cover 2 are provided between the chamber cover 2 and the peeling chamber 1, a dry ice injection port 3 is provided on the side wall of the peeling chamber 1, the dry ice injection port 3 is communicated with an external dry ice storage device, a first solenoid valve 4 is provided between the dry ice injection port 3 and the external dry ice storage device, a carbon dioxide discharge port 5 and an ultrasonic transducer 7 are provided at the bottom of the peeling chamber 1, a second solenoid valve 6 is provided on the outer side of the carbon dioxide discharge port 5, and a microwave generator 8, a position sensor 9 are provided on the inner wall of the peeling chamber 1, and a position sensor 10 are provided on the inner wall of the peeling chamber 1.

By controlling the first solenoid valve 4 using the controller 14, dry ice can be injected into the stripping chamber 1, and the second solenoid valve 6 can be controlled to discharge the carbon dioxide in the stripping chamber 1. The controller 14 can also obtain data information from the position sensor 19 and the pressure sensor 9 to understand the dry ice capacity injected into the stripping chamber 1 and the pressure condition information of the stripping chamber 1, and control the ultrasonic transducer 7 to transmit sound waves to the stripping chamber 1 to enhance the penetration effect of the dry ice, or control the microwave generator 8 to heat the material in the stripping chamber 1, so that the dry ice that penetrates into the surface of the large hard tea blocks sublimates into carbon dioxide gas. The expansion of the dry ice volume can achieve the effect of loosening and stripping the hard tea blocks on the surface.
