Description

TECHNICAL FIELD

[0001] The utility model relates to the production technology field of forsythia tea, specifically to a fixation device for forsythia tea production. BACKGROUND

[0002] In the field of tea processing, forsythia tea, as a kind of beverage with unique health value, its production process has attracted widespread attention. Fixation, as a key step in the processing of forsythia tea, has a crucial impact on tea quality. The main purpose of fixation is to destroy and passivate the oxidation enzyme activity in fresh leaves using high temperature, inhibit the enzymatic oxidation of tea polyphenols and other substances in fresh leaves, evaporate part of the water in fresh leaves, make the tea soft, facilitate rolling and shaping, and at the same time, release the green and pungent smell, and promote the formation of good aroma. In the traditional production of forsythia tea, the fixation efficiency and quality directly determine the quality and production efficiency of the subsequent products.

[0003] Limitations of traditional fixation methods

[0004] Currently, the fixation method in forsythia tea production mainly uses a single rotating fixation cylinder or a simple stirring structure. In these traditional methods, the turning of fresh leaves in the fixation cylinder is not sufficient and the heating is uneven. The single direction rotation often leads to the accumulation of part of the fresh leaves in a certain area of the fixation cylinder for a long time, which cannot effectively contact enough heat, resulting in uneven fixation degree, which seriously affects the quality of forsythia tea. Moreover, due to the limitations of fresh leaf turning during fixation, the fixation efficiency is low, which cannot meet the demand of large-scale production, increasing the production cost and time cost.

[0005] Problems in the unloading process

[0006] In addition, after fixation is completed, taking forsythia tea out of the fixation cylinder is also an important link. The traditional fixation equipment does not fully consider the convenience of unloading in design, and in many cases, manual operation or the help of complex auxiliary tools is needed to take tea out of the fixation cylinder, which not only has high labor intensity, but also easily causes damage to the fixed tea during unloading, affecting the integrity and quality of the tea, and further reducing the efficiency of the whole production process.

[0007] In summary, the existing fixation equipment and process in the production process of forsythia tea have obvious deficiencies in fixation efficiency, tea quality guarantee, and unloading convenience, and an innovative solution is needed to optimize the whole production process. UTILITY MODEL CONTENTS

[0008] The utility model aims to provide a fixation device for forsythia tea production, which solves the problem of uneven heating and inconvenient unloading of the existing fixation equipment mentioned in the background technology.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a forsythia tea production fixing device, comprising a rotating base frame and a fixing mechanism hinged to the rotating base frame. The fixing mechanism includes a base, a coaxial reversing assembly mounted on the base, a fixing drum rotatably connected to the base, and a stirring shaft disposed within the fixing drum. The coaxial reversing assembly is connected to the fixing drum and the stirring shaft respectively. The coaxial reversing assembly drives the fixing drum and the stirring shaft to rotate in opposite directions. A circular heating plate is provided in the interlayer of the drum wall of the fixing drum. An electric slip ring connected to the circular heating plate is provided at the bottom of the fixing drum. The rotating part of the electric slip ring is connected to the bottom of the fixing drum, and the stationary part of the electric slip ring is connected to the base. Blades are provided on the stirring shaft.

[0010] Furthermore, the tilting base includes a U-shaped frame, a cylinder mounted on the U-shaped frame, and a rack that slides vertically within the U-shaped frame; the base is provided with a horizontal rotating shaft, which is hinged to the U-shaped frame and has a gear on it; the output shaft of the cylinder passes through the U-shaped frame and is connected to the rack through a horizontal plate, and the rack meshes with the gear.

[0011] Furthermore, the coaxial reversing assembly includes a motor mounted on the base, a rotating rod passing through the bottom of the blanching drum and connected to the stirring shaft, and a rotating disk rotatably connected to the rotating rod and connected to the bottom of the blanching drum; the output shaft of the motor passes through the base and is connected to the rotating rod, the rotating rod is provided with a first crown gear, the bottom of the rotating disk is provided with a second crown gear, the base is provided with a support plate, and an idler gear is rotatably connected to the support plate, the teeth of the first crown gear and the second crown gear are arranged opposite to each other, and the idler gear is located between the first crown gear and the second crown gear and meshes with the first crown gear and the second crown gear respectively.

[0012] Furthermore, the blanching drum is equipped with a guide plate.

[0013] Furthermore, the cylinder is specifically a multi-section telescopic cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model is used to improve the turning efficiency and heating uniformity of forsythia during the fixation process. A coaxial reversing assembly drives the fixation drum and stirring shaft to rotate, which in turn drives the guide plate inside the drum and the blades on the stirring shaft to rotate. The guide plate rotates in the opposite direction to the stirring shaft, causing the forsythia inside the drum to turn at multiple angles. This prevents the forsythia from accumulating in one area of ​​the drum for extended periods, ensuring it receives sufficient heat to improve the quality of the forsythia tea. Furthermore, by increasing the turning of the forsythia during the fixation process, the fixation efficiency is improved, reducing production costs and time.

[0016] 2. The utility model is used for the forsythia after the killing green ends, and is convenient for unloading the forsythia, through the gear bar rotation driven by the air cylinder, and then drive the gear rotation meshed with it, so as to drive the killing green rotating drum rotation, when the killing green rotating drum rotates to the barrel mouth downward, the forsythia killed in it is poured out, through the mode, it is convenient for unloading the forsythia, thereby reducing the labor intensity and reducing the damage to the forsythia when unloading.
