A kind of tea circulating frying and drying machine

Abstract

The invention discloses a cyclic tea-leaf frying-drying machine and belongs to the field of tea leaf frying-drying machines. The machine comprises a support frame, a cyclic conveyer, a heating device, a power device, an inner barrel, a shell and multiple guide vane plates, wherein the multiple guide vane plates are arranged in the inner barrel in a hovering mode, the shell is fixedly arranged on the support frame, a heat-insulation layer is arranged outside the shell, the cross section of each guide vane plate is in an inverted-V shape, a discharging plate is arranged at the front end of each guide vane plate, shaping plates are arranged among the guide vane plates, the shaping plates and the guide vane plates are opposite in rotating direction, a driving wheel is arranged at one end of the inner barrel, and a driving motor is connected with the driving wheel through a gearing-down mechanism. According to the cyclic tea-leaf frying-drying machine, the cyclic mode is adopted in the tea-leaf frying-drying process, and a great number of defects existing in traditional technologies are overcome.

Description

technical field [0001] The invention relates to a tea drying machine, in particular to a tea circulation drying machine. Background technique [0002] Tea leaves need to be fried and dried in the production process, but the existing tea drying machines have the following deficiencies in the working process: 1. The existing guide vanes are connected from the feed end to the discharge end of the inner cylinder. It is a complete plate structure, so when the tea leaves move to the discharge port, it is easy to be broken by the end of the guide vane, thereby reducing the quality of the tea; 2. The cross-section of the existing guide vane is rectangular, so the tea leaves When stir-frying, the tea leaves will hit the guide leaf plate vertically, which not only increases the breakage rate of the tea leaves, but also makes the tea leaves unattractive and reduces the quality of the tea leaves; Some slag, the existing frying machine can't clean the slag in the tea leaves during the p...

[0002] Tea leaves need to be fried and dried in the production process, but the existing tea drying machines have the following deficiencies in the working process: 1. The existing guide vanes are connected from the feed end to the discharge end of the inner cylinder. It is a complete plate structure, so when the tea leaves move to the discharge port, it is easy to be broken by the end of the guide vane, thereby reducing the quality of the tea; 2. The cross-section of the existing guide vane is rectangular, so the tea leaves When stir-frying, the tea leaves will hit the guide leaf plate vertically, which not only increases the breakage rate of the tea leaves, but also makes the tea leaves unattractive and reduces the quality of the tea leaves; Some slag, the existing frying machine can't clean the slag in the tea leaves during the process of drying, thereby reducing the quality of the tea; After the tea leaves are transported to the feeding end of the inner cylinder, special workers are required to push the tea leaves at the feeding end into the inner cylinder, which is a waste of labor and increases the cost of production. Also can also cause the damage of certain degree to tealeaves, and this not only has reduced the quality of tealeaves, and has also seriously reduced the qualified rate of finished tealeaves; Rotation, the use of friction wheel transmission is not only noisy, but also the transmission stability is low, the friction effect of the friction wheel will decrease after a long time, and it is difficult to play the role of transmission at this time
