Description

[Technical Field]

[0001] . The present invention belongs to the technical field of blue killers, and particularly relates to a blue killer used for fine moisture treatment of tea leaves. [Background technology]

[0002] Steam sterilization of tea leaves is part of the initial processing of green tea, brown rice tea, black tea, oolong tea, pu-erh tea, and some black teas. Its main purpose is to destroy and slow down the oxidative enzyme activity in the fresh leaves at high temperatures, inhibit the enzyme-promoted oxidation of tea catechins in the fresh leaves, and evaporate some of the moisture from the fresh leaves, making the tea leaves softer and more suitable for rolling, while also releasing a refreshing aroma and promoting the formation of a pleasant aroma.

[0003] Chinese Patent CN115997829A discloses a device entitled "Steam Blast-killing Apparatus for Tea Leaves." The device includes a fixed outer container, an inner container rotatably disposed within the outer container, and a drive mechanism for rotating the inner container. The inner container has uniformly distributed holes on its side that communicate with the outer container, preventing tea leaves from passing through the holes. A steam system is connected to the outer container and communicates with the interior, and a supply and exhaust system is located at the top of the outer container, penetrating the ceiling and communicating with the inner container. A drainage mechanism is located at the bottom of the inner container, penetrating the outer container, and a drainage mechanism is connected to the bottom of the outer container. A detection system is installed in the inner container, and the steam blast-killing apparatus is controlled by a controller. The controller is electrically connected to the detection system. "However, this method results in complicated tea leaf blast-killing operations, difficulty in adjusting pressure, temperature, and humidity, and inconvenient standardization of tea leaf blast-killing, resulting in increased tea leaf blast-killing steps and increased costs."

[0004] [Patent Document 1] Chinese Patent No. CN115997829A Summary of the Invention [Problem to be solved by the invention]

[0005] The method described in the literature involves complicated operations for killing tea leaves, and it is difficult to adjust the pressure, temperature, and humidity during the killing of tea leaves, making it difficult to standardize the killing of tea leaves and increasing the number of steps for killing tea leaves. [Means for solving the problem]

[0006] The present invention solves the problems of standardizing tea leaf bleaching and increasing the number of tea leaf bleaching processes by using the following machine. This machine uses minute moisture to treat tea leaves. It includes a support base and a support structure mounted on the support base, which includes a support ring, a frame, a first support wheel, a second support wheel, and a rotating drum attached to the support ring. The rotating drum is equipped with a device for subjecting the tea leaves inside to minute moisture treatment. A motor drive is attached to the side of the support base with a U-shaped screw, and the output shaft of the motor drive is fixed to the rotating drum via a reduction box. A guide plate for rolling the tea leaves is welded to the inner surface of the rotating drum, and an electric heating plate for heating the rotating drum is attached to the upper surface of the support base. A main control box is also attached to the upper surface of the support base. The support structure includes a support ring welded to the upper surface of the support base, a frame arranged annularly on the surface of the support ring, a first support wheel and a second support wheel attached to the frame, and a support ring welded to the outer surface of the rotating drum, with the first support wheel and second support wheel positioned on either side of the support ring. The minute moisture treatment device includes a seal cover plate attached to the opening of the rotary drum, an exhaust pump attached to the upper surface of the seal cover plate, a pressure sensor for monitoring the pressure inside the rotary drum, a temperature sensor attached to the upper surface of the seal cover plate for monitoring the temperature inside the rotary drum, a water replenishment tank attached to the upper surface of the seal cover plate, and a mist nozzle attached to the lower surface of the seal cover plate.

[0007] The mist nozzle is attached to the water outlet of a mini water pump installed in the water supply tank. A sub-control box is also attached to the upper surface of the seal cover plate, and a humidity sensor is also attached to the upper surface of the seal cover plate. As a preferred technical means of the micro-moisture treatment and killing machine for tea leaf processing of the present invention, a block ring is integrally molded into the open end of the rotating drum, and a seal groove that fits the block ring is provided on the lower end of the seal cover plate. A screw, threaded with a nut, is welded to the surface of the block ring and passes through a hole opened in the surface of the seal cover plate.

[0008] In a preferred technical means of the micro-moisture treatment and blue killing machine for tea leaf processing of the present invention, six screws to which block rings are welded are evenly arranged. In a preferred technical means of the micro-moisture treatment and blue killing machine for tea leaf processing of the present invention, seven frames are arranged on the upper surface of the support ring, and the frames are "T"-shaped metal rods. The first support wheel and second support wheel attached to the frames are arranged perpendicular to each other. The upper surface of the electric heating plate is arc-shaped, and the minimum distance between the electric heating plate and the rotating drum is 2 mm. In a preferred technical means of the blue killing method of the micro-moisture treatment and blue killing machine for tea leaf processing, the following steps are included: Step 1, low-temperature, high-pressure evaporation, lasting 4 minutes; Step 2, high-temperature, low-pressure blue killing, lasting 9 minutes; Step 3, high-temperature, high-pressure sterilization, lasting 1 minute; Step 4, low-temperature, low-pressure flavoring, lasting 13 minutes. The preferred technical means for the blue killing method of the micro-moisture processing blue killing machine for tea leaf processing are a blue killing temperature of 0-50°C, a rotary drum rotation angular speed of 90 r / min, a pressure of 5 kPa, and a humidity of 85%; in step 1, a blue killing temperature of 100-150°C, a rotary drum rotation angular speed of 150 r / min, a pressure of 0.5 kPa, and a humidity of 25%; in step 3, a blue killing temperature of 150-200°C, a rotary drum rotation angular speed of 200 r / min, a pressure of 5 kPa, and a humidity of 23%; and in step 4, a blue killing temperature of 30-20°C, a rotary drum rotation angular speed of 30 r / min, a pressure of 0.4 kPa, and a humidity of 21%.

[0009] In the preferred technical method of the blue killing method for the micro-moisture processing blue killing machine for tea leaf processing, the temperature of low-temperature, high-pressure evaporation in step 1 is a proportional function. In step 1, the temperature of the rotary drum rises from 0°C to 50°C over the first three minutes and remains constant at 50°C for the last minute. In step 2, the temperature of high-temperature, low-pressure blue killing is also a proportional function. In step 2, the temperature of the rotary drum rises from 100°C to 150°C over the first six minutes and remains constant at 150°C for the last three minutes. In step 3, the temperature of high-temperature, high-pressure sterilization is also a proportional function. The temperature of the rotary drum rises from 150°C to 200°C within one minute. In step 4, the temperature of low-temperature, low-pressure aromatization is also a proportional function. In step 4, the temperature of the rotary drum drops from 30°C to 20°C over the first 10 minutes and remains constant at 20°C for the last three minutes. [Effects of the Invention]

[0010] TIFF2025155446000002.tif9152Support for the drum. The support structure consists of a support ring, a frame, a first support wheel, a second support wheel, and a drum attached to the support ring. At the same time, there is a ring-shaped frame on the support ring, which supports the first and second support wheels, and the first and second support wheels support the support ring. This structure allows the support base plate to support the drum through the support structure, ensuring the stability of the tea leaves being sterilized inside the drum. The miniature moisture treatment device installed on the drum helps to control the pressure inside the drum through the exhaust pump in cooperation with the exhaust and pressure sensor. The sealing cover plate and electric heating plate work together to control the temperature inside the drum, thereby realizing control of the temperature and pressure during tea leaf sterilization. At the same time, the water replenishing tank, mist nozzles, and humidity sensors replenish moisture inside the drum, ensuring that the humidity during tea leaf sterilization is not too low and that carbonization does not occur during high-temperature sterilization of the tea leaves. This standardizes the tea leaf sterilization process, reduces the number of steps, and reduces the cost of tea leaf sterilization. [Brief explanation of the drawings]
