Abstract
The tea dryer adopting far infrared heating is composed of a conveying driving device 1, a main body 2, a conveying belt 3, a conveying driving device 4, a control system 5, an upper far infrared film heater 6, a lower far infrared film heater 8, an air driving device 9 and a conveying belt supporting body 7; the equipment during operation, the tealeaves of treating to dry is imported on one side by conveyer belt 3, carry to the another side of equipment under the drive of conveyer belt 3, in transportation process, tealeaves receives the stoving of upper far infrared membrane heater 6, the hot-air that still receives lower far infrared membrane heater 8 and air drive device 9 transport simultaneously blows roast, the inside temperature of control system 5 sensing main part 2 and the actual tealeaves output that toasts, the power of upper far infrared membrane heater 6 and lower far infrared membrane heater 8 are controlled, the air supply speed of air drive device 9 still is controlled simultaneously, still control and carry drive device 1 and carry drive device 4 to drive the conveying speed of conveyer belt 3, reach the effect of toasting that needs.
Description
Technical Field
The invention relates to tea drying equipment, in particular to a tea dryer adopting far infrared heating.
Background
The common tea drying equipment adopts a heater which adopts a common heating pipe for heating, and the heating technology has the defects of uneven heating, large temperature error, inaccurate temperature control, damage to the equipment and influence on the drying quality of the tea.
The invention aims to adopt a heating mode combining far infrared film heater heating, radiation heating and hot air heating, and utilize the characteristics of large-area heating, extremely low heat capacity and extremely low temperature control overshoot of the far infrared film heater, so as to increase the uniformity of heating and the precision of temperature control and provide the tea drying quality.
The technical scheme of the invention is realized as follows: adopt the conveyer belt to carry tealeaves, the face electric heat far infrared membrane heater that the installation toasted the heating above the conveyer belt, the face electric heat far infrared membrane heater of air drive's motor and heated air is installed below the conveyer belt, and the air that heats sees through netted conveyer belt can blow on the tealeaves of carrying for tealeaves is heating and hot-blast effect down quick, even stoving to the degree of needs.
Drawings
Fig. 1 is a schematic overall appearance structure of the present invention.
FIG. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
Embodiments of the invention are described in detail below with reference to the following figures:
referring to fig. 1 and 2, the tea dryer adopting far infrared heating is composed of a conveying driving device 1, a main body 2, a conveying belt 3, a conveying driving device 4, a control system 5, an upper far infrared film heater 6, a lower far infrared film heater 8, an air driving device 9 and a conveying belt supporting body 7; the control system 5 is connected with the conveying driving device 1, the main body 2, the conveying driving device 4, the upper far infrared film heater 6, the lower far infrared film heater 8 and the air driving device 9 through wires; the main body 2 is of a cavity structure, and an upper far infrared film heater 6 is arranged on the inner surface of the upper part of the main body; the conveyer belt 3 is a horizontal or nearly horizontal breathable and heat-resistant soft film and closed-loop structure, and the conveyer belt 3 is driven to rotate by the conveying driving device 1 and the conveying driving device 4; a conveyer belt supporting body 7, a lower far infrared film heater 8 and an air driving device 9 are arranged below and above the closed loop of the conveyer belt 3; the conveyer belt supporting body 7 can be a high-temperature-resistant smooth perforated structure or a roller structure with a mounting gap, and hot air can pass through; the two sides of the upper surface of the conveying belt 3 are provided with baffle structures 10 which can prevent tea leaves from falling into the gaps at the two sides of the conveying belt 3.
The equipment during operation, the tealeaves of treating to dry is imported on one side by conveyer belt 3, carry to the another side of equipment under the drive of conveyer belt 3, in transportation process, tealeaves receives the stoving of upper far infrared membrane heater 6, the hot-air that still receives lower far infrared membrane heater 8 and air drive device 9 transport simultaneously blows roast, the inside temperature of control system 5 sensing main part 2 and the actual tealeaves output that toasts, the power of upper far infrared membrane heater 6 and lower far infrared membrane heater 8 are controlled, the air supply speed of air drive device 9 still is controlled simultaneously, still control and carry drive device 1 and carry drive device 4 to drive the conveying speed of conveyer belt 3, reach the effect of toasting that needs.
Because the far infrared film heater is adopted for heating, and the heating mode combining radiation heating and hot air heating is adopted, the characteristics of large-area heating, extremely low heat capacity and extremely low temperature control overshoot of the far infrared film heater are utilized, the heating uniformity and the temperature control precision are improved, and the tea drying quality is provided.
Wherein the upper far infrared film heater 6 and the lower far infrared film heater 8 comprise insulation protection devices.
The tea dryer adopting far infrared heating can be used by connecting a plurality of machines, thus the temperature of each conveying area of the tea which is heated in a flowing way can be controlled to adapt to the technical requirements of manufacturing various tea.
