Tea leaf aroma extraction device for tea frying

By employing a double-layer drum structure and an inflatable silicone lifting plate design, the problem of uneven heating and high breakage rate of tea leaves in traditional tea frying machines is solved. This achieves uniform heating of tea leaves and reduces the breakage rate. The structure is reasonable, using a double-layer drum structure. The inner layer is made of stainless steel perforated mesh, and the outer layer is made of silicon carbide insulation layer. Six sets of carbon fiber heating plates are used in the circumference, covering the 360° circumference of the drum. This coverage ensures uniform heating of the tea leaves and guarantees the aroma enhancement effect. In addition, the inflatable silicone lifting plate effectively reduces the breakage rate of tea leaves, achieving uniform aroma enhancement of the tea leaves.

AI Technical Summary

Technical Problem

Traditional drum-type tea frying machines cause uneven heating of tea leaves due to a single heating source, and the shearing force generated by the rotation of the metal stirring plate and the drum results in a high rate of tea leaf breakage.

Method used

It adopts a double-layer drum structure, with the inner layer made of stainless steel perforated mesh and the outer layer of silicon carbide insulation layer. Six sets of carbon fiber heating plates are installed around the circumference, and in conjunction with inflatable silicone lifting plates, the tea leaves are heated evenly and broken by means of PLC controller and electric push rod.

Benefits of technology

It achieves uniform heating of tea leaves, reduces tea breakage rate, ensures aroma enhancement, has a reasonable structure, and is highly practical.
