Abstract:
That traditional panning machine is used for fresh tea leaves panning, but with the well ventilation, caused the temperature distribution of the inner panning machine is not uniform. The feeding hole make the traditional panning machine strong convection, so let the temperature hot on the middle panning machine, and let the temperature cold near the feeding hole. The highest temperature difference is 125℃ between difference place of the machine wall, and the highest temperature difference is 98℃ between difference place of the inside air, so it make the tea panning quality bad. To solve the question of the temperature distribution, adding the air door on the feeding hole, it can stop the environment cold air to enter the panning machine. Let the temperature distribution of panning machine wall better. The highest temperature difference of the panning machine wall from 125℃ to 56℃, and the highest temperature difference of the panning machine wall from 98℃ to 31℃ From the organoleptic evaluation, adding the air door can promote the tea quality. We had success develop and design to add the hot air machine with the electrical panning machine. In the future, we will add the hot air machine with the gas panning machine, and promote the tea quality. In the future, we will add the hot air machine with the gas panning machine, and promote the tea quality.
