Ventilation type constant-temperature-and-humidity tank for tea leaf fermentation

Abstract: A ventilation type constant-temperature-and-humidity tank for tea leaf fermentation comprises a tank top and a tank bottom, a tank door, a side plate and a bottom plate are arranged on a front tank plate arranged between the tank top and the tank bottom, a handle and an observation window are arranged on the tank door, a control panel is arranged on the side plate, a lattice window is arranged on the bottom plate, a test hole is arranged in a fermentation chamber, a bottom control chamber corresponding to the lattice window is arranged under the fermentation chamber, a humidifying unit, a heating unit and an air intake device are arranged on the side of the fermentation chamber, a cooling unit cooperating with the heating unit and a ventilator cooperating with the air intake device are arranged in the bottom control chamber, the humidifying unit, which is an electric heating type humidifier, comprises a humidifier and an evaporator which cooperate with each other, a pxw-9 temperature-humidity controller is arranged on the humidifying unit, and the air intake device, which is a centrifugal convection fan, comprises blades and a fan. The constant-temperature-and-humidity tank not only has high temperature-humidity control precision and a good ventilating effect, but also has good coordination between ventilating operation and accurate constant-temperature-and-humidity control.

Drum type tea cooling and damping machine

Abstract: A drum type tea cooling and damping machine comprises a bracket, a cooling part, a transition part and a damping part, wherein the cooling part, the transition part and the damping part are sequentially arranged on the bracket and form a drum type structure; drum rotating equipment and a bearing support component used for regulating an inclined angle of a drum are respectively arranged at a cooling feeding end, a transition feeding end and a damping feeding end; the drum rotating equipment comprises a large chain wheel, a chain, a small chain wheel and a motor, wherein the outer part of the large chain wheel is connected with the motor through the chain and the small chain wheel; the bottom of the motor is fixed on a motor seat through a bolt; a motor regulation hinged support, a motor regulation screw and a chain tension spring are arranged between the motor seat and a motor component base; the cooling part comprises an outer drum, an inner drum and a separation plate; the outer drum is provided with an exhaust port, a suction port and a dregs collecting bin; and an air vent is arranged on the inner drum Due to the design, the cooling and damping effect is better, no fannings can be generated, and the drum type cooling and damping machine has the advantages of simple structure and convenience in use and maintenance
