Embodiment 1
[0023] Embodiment one: fumigation of cooked tea paste or tea powder
[0024] Take 30 kg of ripe Pu-erh tea leaves with excellent aroma, and place them evenly on a shelf for placing tea leaves built with about 15 layers of stainless steel screens. The aperture of the screens is 60 mesh, and the thickness of each layer of tea leaves is 30 mm. Put the shelves for placing tea leaves in a closed stainless steel tea container with a volume of 500 liters, or other heat-resistant, odor-free containers that meet food processing requirements. Heat the air in the tea container in a closed environment, and control the heating of the hot air blower through the thermometer installed on the tea container: raise the temperature in the container to 85 degrees and keep it for at least 20 minutes; install a stainless steel valve with a gate valve on the top of the tea container The air-introduction pipe, the outlet end of the air-induction pipe is connected with the coil condenser, and the coil ...
