Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of black tea fermentation, in particular to a black tea fermentation device capable of precise temperature control. BACKGROUND

[0002] Black tea fermentation is a key process for determining its quality and flavor formation, and has extremely stringent requirements for temperature, humidity and oxygen environment. Traditional fermentation processes mostly use natural fermentation or simple mechanical fermentation equipment, which still has certain drawbacks. 1. Temperature and humidity control is extremely inaccurate and easily affected by environmental fluctuations. The temperature and humidity in the same space are not completely consistent, which can easily lead to uneven fermentation of the same batch of tea and unstable quality. 2. Tea is usually fermented by stacking, which has poor internal ventilation and is prone to sour taste. In addition, the waste liquid and waste gas generated during fermentation cannot be discharged in time, which seriously affects the pure flavor of the tea. 3. After fermentation is completed, it needs to be transferred to other equipment for drying, which is complicated and has the risk of secondary pollution. Therefore, the industry urgently needs an integrated fermentation device that can achieve precise temperature and humidity control, uniform oxygen supply, and automatic waste discharge and integrated drying function to ensure high-quality and standardized production of black tea fermentation.

[0012] Compared with the prior art, the present application has the following beneficial effects: 1、The present application can precisely control the environment of tea leaves layer by layer through the setting of the storage assembly and the drainage assembly, that is, through the unique design of the drainage assembly, the mixed gas generated by the precision control unit is transported to the annular inner cavity of the storage box through the guide cavity, the guide block and the connecting groove, and finally acts directly on the tea leaves on each layer of the storage plate through the uniformly distributed connecting holes, so that the point-to-point air supply mode breaks the pattern of uneven environment in the warehouse of the traditional equipment, ensures that each layer and each part of the tea leaves can be in a completely consistent ideal fermentation environment, thereby ensuring the uniformity and stability of the fermentation degree of the whole batch of tea leaves, and significantly improving the quality of the black tea product.

[0013] 2、The present application can discharge concentrated waste liquid and waste gas through the setting of the waste discharge assembly, specifically, the waste liquid collection channel composed of the funnel-shaped storage plate, the drainage groove, the guide cylinder, the matching cavity and the through groove can efficiently guide the waste liquid generated during fermentation to the waste chamber for temporary storage, and when the movable plate is rotated to a specific position, the unique waste discharge assembly automatically opens the valves of the connecting pipe and the matching pipe through the mechanical linkage of the trigger block and the matching rod, and the waste liquid and waste gas are sucked and discharged through the discharge pipe, which not only avoids the secondary pollution of waste liquid soaking tea leaves and waste gas, but also improves the waste discharge efficiency by using the waste gas flow to accelerate the liquid discharge, and simultaneously makes the air exchange operation and the waste discharge operation run synchronously, thereby improving the equipment use efficiency.

[0014] 3、The present application can realize mechanical flow regulation and over-temperature protection through the setting of the temperature sensing element and its peripheral components, specifically, the temperature sensing element arranged in the drainage assembly can deform according to the actual temperature in the cabinet sensed by the detection groove, automatically drive the blocking block to adjust the opening degree of the guide cavity inlet, thereby real-time feedback regulating the air inlet amount of the mixed gas, forming an autonomous negative feedback control structure to keep the temperature in the cabinet dynamically stable, and when the internal temperature is abnormally high, the deformation of the temperature sensing element can make the blocking block completely block the guide cavity, automatically cut off the hot air supply, thereby providing a pure mechanical over-temperature protection mechanism, which double guarantees the safety and precision of the fermentation process.

[0015] 4、The present application can be used in multiple ways by setting the precision control unit, the storage assembly, the drainage assembly and the waste discharge assembly. Specifically, after the fermentation process is completed, the precision control unit is switched to output only dry hot air, and the original gas channel and waste discharge channel are used to dry the tea leaves at low temperature in the same device. After the airflow passes through the tea leaves and carries away the moisture, it enters the waste discharge system through the guide cylinder and is discharged, forming a complete drying process. The step of transferring and handling the fermented tea leaves is eliminated, which reduces labor costs and quality loss.

[0016] 5、The present application can supply the channel liquid discharge operation by setting the matching pipe and its peripheral components. Specifically, when the connecting pipe and the matching pipe are in the corresponding position, the internal components of the connecting pipe and the matching pipe mechanically trigger the communication therebetween. At this time, the liquid accumulated at the bottom wall of the guide cavity can flow into the inside of the waste cavity for centralized discharge operation, avoiding the influence of water accumulation in the channel on subsequent environmental control.

[0017] 6、The present application can automatically and uniformly spread the material by setting the storage assembly. Specifically, the motor drives the movable plate to drive the entire storage assembly to reciprocate at a specific angle, and the inertia makes the tea leaves spread on the storage plate net surface, realizing automatic and uniform material distribution after feeding and ensuring the uniformity of fermentation.
