Description

Tea fermentation stir-frying equipment with multistage air flow regulation and control Technical Field The invention relates to the technical field of tea processing, in particular to tea fermentation and stir-frying equipment with multi-stage air flow regulation and control. Background In the field of tea processing, fermentation and stir-frying are key links for determining tea quality, and air flow regulation and control technology plays a vital role in the two links. Along with the development of industrialization and automation of tea processing, fermentation stir-frying equipment integrating a multi-stage airflow regulation and control function gradually becomes mainstream, and the fermentation uniformity and the stir-frying stability of tea can be effectively improved by accurately controlling parameters such as temperature, humidity and flow of airflow, and the cost of manual intervention is reduced. However, in the actual operation of the conventional tea fermentation and stir-frying equipment with multi-stage air flow regulation, two outstanding problems still exist, and the processing efficiency and the tea quality are seriously affected: On the one hand, the air outlet is easy to be blocked by tea. In the fermentation stage, the tea leaves are easy to adsorb and accumulate near the air outlet under the action of air flow due to moisture or viscous substances contained in the tea leaves, and in the stir-frying stage, the tea leaves can generate broken slag and powder after stir-frying, and when the fine particles move along with the air flow, the fine particles are very easy to be blocked in a grid or a pipeline gap of the air outlet, so that the air flow is blocked. Once the air outlet is blocked, the air flow circulation balance inside the equipment can be damaged, parameters such as temperature, humidity, oxygen concentration and the like deviate from set values, insufficient tea fermentation and uneven stir-frying heating are caused, the equipment is partially overloaded possibly due to sudden increase of air flow pressure, and the service life is shortened. On the other hand, the air outlet pipe body is easy to loose under the action of wind flow pressure. In the multi-stage airflow regulation and control process, the equipment needs to frequently regulate the flow and pressure of the airflow, for example, the low-pressure airflow in the initial fermentation stage is switched with the high-temperature and high-pressure airflow in the frying stage, and the periodic change of the airflow pressure can generate continuous impact and vibration on the connection part of the air outlet pipe body and the equipment cavity. The traditional connection mode, such as bolt fixing and buckle connection, is easy to cause the problems of gap increase, fatigue failure of the fastener and the like under the action of long-term alternating stress, so that the pipe body loosens and even falls off. The air flow leakage can be caused, the regulation and control precision is reduced, abnormal sound and abrasion can be generated due to collision of the pipe body with other parts, and potential safety hazards exist. Therefore, a tea fermentation and stir-frying device with multi-stage air flow regulation is provided to solve the problems.
