Novel automatic drier

Abstract

The invention relates to a novel auto dryer, comprising a drying chamber and a left-right rotary type circulation chain transmission mechanism; the transmission chain of the chain transmission mechanism is positioned on two sides of a holding changeover. The path corner of each layer transmission chain is provided with a turning transmission chain wheel; the holding changeover is articulated with the transmission chain at two side ends in operation direction; the lower part of each layer transmission chain is provided with lead rails positioned at the lower part of the holding changeover for supporting the transmission chain and the holding changeover; each layer of the lead rails is provided with a material falling mouth for facilitating the rear of the changeover to droop near one side of turning to the direction of the transmission chain wheel at the end part of the holding changeover operation direction. The transmission chain goes upwards along a material-feeding slope to the top layer, turns to the last third layer, the last second layer and the last layer, then turns towards the last fourth layer after going through a small up tramp slope, then goes upwards layer by layer, turns to the second layer after going through a down tramp slope and finally turns to the material-feeding slope; the dryer has reasonable design on walking route with better sealing effect and can make full use of heat energy and is in favor of evenly drying tea leaves.

Description

Technical field: [0001] The invention relates to a novel automatic dryer, in particular to a dryer for drying tea leaves. Background technique: [0002] The tea dryers that people use now form an endless reciprocating mechanism in the drying room with two drying layers. There are disadvantages: one is that a cycle composed of two drying layers requires an independent driving mechanism, and the structure is complex and difficult to operate and maintain. Inconvenient, the drying temperature of tea leaves in such a drying layer structure is extremely uneven, resulting in the quality of tea leaves cannot be guaranteed; second, tea leaves are prone to tea clipping and bridging during the moving process, resulting in tea leaves not falling completely into the next layer. It often falls outside the machine, resulting in a low output rate; there is also a top-to-bottom, left-right rotation conveying method that has the disadvantage of poor sealing, and a guard must be used at the lo...
