Abstract

The invention relates to a drum type tea drying machine using an electric heating device with an air guide cover. The upper left end of the cylinder (21) for drying tea leaves is provided with a feed inlet (22) for adding tea leaves, and the lower right end of the cylinder (21) is provided with a discharge outlet (23) for discharging tea leaves. There is an electric heater body (1) that supplies hot air to the drum (21); the air is blown into the heating zone (3) by the fan (6) installed in front of the air inlet (4), and the heating zone (3) is equipped with The air is heated using an electric heating device with an air shroud. The beneficial effects of the present invention are: the present invention has the advantages of simple structural design, convenient use and operation, rapid acquisition of high-heat air, and effective automatic temperature control.

Description

technical field [0001] The invention relates to a drum type tea drying machine using an electric heating device with an air guide cover. Background technique [0002] At present, there are many types of electric heaters. Generally, when the heating medium passes through the heating chamber of the electric heater under pressure, the huge heat generated by the electric heating element is uniformly taken away by the principle of fluid thermodynamics, so that the temperature of the heated medium reaches User process requirements. The air electric heater generally refers to passing the air through the air electric heater to increase the temperature of the gas and then transport it to the next working link. Due to the particularity of the air medium, it consumes more energy, and it is easy to lose and waste heat energy. Tea dryers using electric heating have the problem of low thermal efficiency. Contents of the invention [0003] The technical problem to be solved by the pre...
