Description

Technical Field

[0001] The invention relates to the technical field of tea processing equipment, and in particular to a mounting mechanism for a conveying device of a tea drying machine. Background Art

[0002] During the tea processing and production process, tea leaves need to be dried to remove moisture from the tea leaves, reduce the moisture content in tea cells, reduce their activity and remove the semi-permeability of the cell membrane, so as to ensure that the subsequent processing can normally produce high-quality tea leaves. It can be seen that the quality of tea leaves will be directly affected by the quality of tea leaves. There are three main methods of tea leaf drying: drying, frying and sun drying. For the drying process of green tea, it is generally dried first and then fried. Because the water content of tea leaves after rolling is still very high, if they are fried directly, they will quickly form lumps in the pot of the frying machine, and the tea juice will easily stick to the pot wall. Therefore, the tea leaves are first dried to reduce the water content to meet the requirements of pan frying.

[0003] In the process of drying tea leaves in the existing dryer, the tea leaves cannot be evenly distributed in the dryer, and the tea leaves will pile up together, which affects the drying effect of the tea leaves. In order to solve the problem of tea leaves piling up and uneven drying during the drying process, the existing dryer generally adds a conveying device with a flap structure, and the tea leaves in the dryer are turned over and dried by the flap, so as to improve the drying quality of the tea leaves. However, the conveying device of the existing dryer, because the motor that provides power to the conveying device is generally installed on the outside of the drying box, the motor drives the conveying device to move through the mounting mechanism set in the drying box, and there is a gap between the mounting mechanism and the side wall of the drying box, so that it is easy to cause the hot air in the drying box to be discharged from the gap, thereby causing heat energy waste, which not only increases the tea processing cost, but also affects the drying quality of the tea leaves, greatly restricting the promotion and use of tea dryers with flap structures. Therefore, in order to improve the utilization rate of hot air and reduce heat energy loss, it is necessary to improve the existing mounting structure for driving the conveying device to move, so as to provide a mounting mechanism for the conveying device of the tea dryer, so as to meet the conveying needs of the existing conveying device. Summary of the invention
