Embodiment 1

[0043] A kind of hot air internal circulation type tea mill, such as Figure 1-8 As shown, it includes a furnace body 1, the bottom of the furnace body 1 is provided with an adjustable support frame, one end of the furnace body 1 is integrally provided with a gathering bucket 7, and the outer wall of the bottom of the gathering bucket 7 is connected with a discharge door 4 through a hinge. 1. A drying fan 6 is installed on the inner wall of one end through the fan seat, and the furnace body 1 is installed at an inclination as a whole. The level of the discharge door 4 is lower than that of the drying fan 6. The inner wall of the top of the furnace body 1 is detachable by screws. More than two installation frames 11 are installed, and the outer wall of the bottom of the installation frame 11 is rotatably installed with the same rotating main shaft 17, and more than two confluence mechanisms are arranged on the outside of the circumference of the rotating main shaft 17, and the i...

Embodiment 2

[0052] A kind of drying method of the hot air internal circulation type tea milling stove, such as Figure 1-9 shown, including the following steps:

[0053] S1: adjust the inclination angle of the furnace body 1;

[0054] S2: adjust the effective length of the elastic cord 5 through the fixed knob 31;

[0055] S3: Control the operation of the drying fan 6 to preheat the furnace body 1;

[0056] S4: Add tencha to be dried into the feeding port 2;

[0057] S5: Tencha passes through various confluence mechanisms, is fully dried by hot air, and then is automatically unloaded from the discharge door 4;

[0058] S6: Collect the tencha, and after drying, open the discharge door 4 to collect the remaining tencha.

[0059] In order to ensure the taste of the product; Figure 9 As shown, in the S1 step, the angle between the furnace body 1 and the horizontal plane is controlled at 15-40°, even 25°.

Abstract

The invention discloses a hot air internal circulation type tea-milling furnace and a drying method thereof, and relates to the technical field of tea-milling drying; in order to improve the drying effect; the tea-milling furnace includes a furnace body, and an adjustable support is arranged at the bottom of the furnace body One end of the furnace body is integrated with a gathering hopper, the outer wall of the bottom of the gathering hopper is connected with a discharge door through a hinge, the inner wall of one end of the furnace body is installed with a drying fan through the fan seat, and the whole furnace body is inclined; The dry method includes the following steps: adjusting the inclination angle of the furnace body; and adjusting the effective length of the elastic rope through a fixing knob. In the present invention, structures such as a confluence plate and an elastic wrinkle ring are arranged, and the whole furnace body is arranged at an inclination, so that the milled tea is constantly approaching the discharge door under the conveyance of hot air and its own gravity, and multiple confluence plates and elastic wrinkle rings can achieve convergence. The wind force and the purpose of grinding the tea make the outer surface of the grinding tea fully in contact with the hot air to ensure the drying effect.

Description

technical field [0001] The invention relates to the technical field of tea-milling drying, in particular to a tea-milling furnace with internal circulation of hot air and a drying method thereof. Background technique [0002] Tencha is the raw material tea of ​​matcha. In fact, tencha is the primary steamed green tea, and matcha is the refined tea of ​​tencha. In the production of matcha, tencha needs to be dried. Although the traditional tencha furnace has certain drying requirements, But only use the internal high-temperature air to dry the tea leaves on the conveyor belt, take away the moisture, and the drying time is longer, and the ground tea is placed on the conveyor belt, so it cannot be dried in all directions, so that the drying effect is not good. ideal. [0003] After searching, the Chinese patent application number is CN201810398511.1, which discloses a tea grinding furnace, including a furnace body, which is respectively provided with a leaf inlet port and a te...
