Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fixation device, concretely relates to a tea leaf processing fixation device. BACKGROUND

[0002] The fixation device in tea leaf processing is one of the key equipment in the tea leaf production process, and its principle is mainly to destroy and passivate the oxidation enzyme activity in fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make the tea soft, facilitate the rolling and shaping, and promote the formation of good aroma by emitting the green and smelly smell.

[0003] The traditional tea leaf processing fixation device has some deficiencies, for example, some fixation devices adopt the roller type or pot type structure, and the tea leaves are easy to be unevenly heated in it, resulting in that part of the tea leaves is over-fixed and part of the tea leaves is under-fixed, which affects the consistency of tea quality, and some steam fixation devices can better retain the natural aroma and nutritional components of tea leaves, but the fixation efficiency is relatively low, and the equipment cost is high, in addition, the existing fixation device also has limitations in the turning and heating mode of tea leaves, and the tea leaves often need to be manually or mechanically turned in the processing process to ensure uniform heating, but this way not only has high labor intensity, but also is difficult to realize accurate control, at the same time, the traditional heating mode is often difficult to make the tea leaves uniformly heated in a short time, which affects the fixation effect and speed, therefore, a tea leaf processing fixation device is needed to solve the above problems.

[0026] The lower surface of the processing machine frame 1 is fixedly provided with a plurality of supporting legs 7, and the plurality of supporting legs 7 are jointly and fixedly provided with a bottom fixed block 8, and the bottom fixed block 8 is fixedly provided with a driving motor 9. By arranging the driving motor 9, the rotation of the fan 5 and the material supporting disc 2 can be driven under the driving of the driving motor 9. The rotation of the material supporting disc 2 can further improve the uniform stirring effect of the tea leaves on the material supporting disc 2. The rotation of the material supporting disc 2 cooperates with the hot air to form a three-dimensional circulating flow path for the tea leaves in the processing machine frame 1. The tea leaves are gradually brought to the edge of the material supporting disc 2 from the bottom of the material supporting disc 2, and then move upward under the blowing of the hot air, and fall back to the center of the material supporting disc 2 or other positions under the action of gravity after reaching a certain height.

[0027] The lower surface of the processing machine frame 1 is fixedly provided with a filter air window 10, and the bottom end of the fan 5 is rotatably arranged on the filter air window 10.

[0028] By arranging.

[0029] The output shaft of the driving motor 9 is fixedly connected with the rotating part of the lower surface of the fan 5. The upper surface of the processing machine frame 1 is communicatively provided with a hopper cover 11. The hopper cover 11 is reversely arranged above the cylinder. When the hot air carrying water vapor is discharged upward, the hot air is guided back to the inside of the cylinder due to the guidance of the narrow inner wall of the hopper cover 11. This design greatly enhances the recycling of hot air, so that the hot air can continuously flow in the processing machine frame 1 and continuously provide heat for the tea leaves, thereby improving the utilization efficiency of heat and reducing the waste of energy.

[0030] The hopper cover 11 is communicatively provided with an air outlet 12.

[0031] The processing machine frame 1 is provided with an inlet and outlet 13.

[0032] The working principle and usage process of the utility model are as follows: first, by arranging a fan 5 under the feeding tray 2, when the fan 5 is driven to rotate, it will blow air from bottom to top into the processing machine frame 1, so that the tea leaves placed on the feeding tray 2 can be blown. During this period, the hot air generated by the rotation of the fan 5 will be blown back to the tea leaves evenly through the air holes 3 on the feeding tray 2, so that each piece of tea leaves can be fully exposed to the heat in a short time, avoiding the problems of local overheating or uneven heating that may occur in the traditional tea leaf withering method. The tea leaves are constantly rolling and floating under the action of the hot air, ensuring that each part can be evenly withered, thereby improving the quality consistency of the tea leaves. The combination of the electric heating rod 6 and the fan 5 can quickly heat up and maintain a stable high temperature environment, providing a reliable heat source for tea leaf withering. At the same time, the design of the air holes 3 enables the hot air to act on the tea leaves in a more dispersed manner, further enhancing the heating uniformity. The turning of the tea leaves in the process is all mechanical wind blowing, without manual turning. In addition, by arranging a driving motor 9, the driving motor 9 can The rotation of the fan 5 and the supporting tray 2 can further improve the uniform turning effect of the tea leaves on the supporting tray 2. The synergistic effect of the rotation of the supporting tray 2 and the hot air causes the tea leaves to form a three-dimensional circulation flow path in the processing machine frame 1. The tea leaves are gradually brought from the bottom of the supporting tray 2 to the edge of the supporting tray 2, and then move upward under the blowing of the hot air. After reaching a certain height, they fall back to the center of the supporting tray 2 or other positions under the action of gravity, and so on. This circulation flow makes the residence time of the tea leaves in the fixing device more reasonable, makes full use of the space and heat resources in the device, and further improves the fixing efficiency. By setting the bucket-shaped cover 11, the bucket-shaped cover 11 is reversely set above the cylinder. When the hot air carries water vapor and is discharged upward, due to the guidance of the narrow inner wall of the bucket-shaped cover 11, the hot air will be redirected back to the inside of the cylinder. This design greatly enhances the recycling of hot air, so that the hot air can continue to flow in the processing machine frame 1, continuously providing heat for the tea leaves, thereby improving the heat utilization efficiency and reducing energy waste.
