A flue-cured tobacco heat pump dual power barn

Abstract

The invention discloses a flue-cured tobacco heat pump dual-power barn, which includes a flue-cured tobacco room, a heating room, a heat pump unit, and a biomass fuel furnace. The heating room is sealed and adjacent to the flue-cured tobacco room. The air outlet, the heating room is provided with a diversion wall facing the return air outlet, the heat pump evaporator of the heat pump unit is installed facing the air outlet, a heat exchange device is installed above the heat pump evaporator, and a guide fan is installed above the heat exchange device. The heat pump condenser of the heat pump unit is arranged at the tuyere, a biomass fuel furnace and a control device are arranged in the heating room, and a monitoring system connected to the control device is arranged in the flue-cured tobacco room. The invention realizes automatic control through the control device, can finely and stably adjust the temperature change, and has high heat utilization efficiency. Compared with other roasting methods, the roasting cost is low and energy-saving, and the tobacco leaf roasting modulation loss is reduced, and the tobacco leaves turn yellow and fix the color. Coordination, matching of drying and aroma, to achieve the goal of roasting tobacco leaves to be yellow, dry and fragrant.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing equipment, and in particular relates to a flue-cured tobacco heat pump dual-power curing room that can effectively reduce energy consumption and improve heat utilization efficiency. Background technique [0002] With the rapid development of the tobacco industry, the demand for tobacco leaves is getting higher and higher. The production of high-quality tobacco leaves is the main direction of future development. The development of tobacco through science and technology has become the main theme of the development of traditional agriculture to modern tobacco leaves. Using advanced science and technology to highlight the supporting facilities of the curing barn, continuously improving the internal and external quality of tobacco leaves, reducing labor intensity and production costs, and increasing economic benefits have become the necessary means for the main competitive tobacco market at this ...

Problems solved by technology

Although electromagnetic heating heats up quickly, it consumes a lot of energy, has low thermal efficiency, and is not energy-saving; while electric heating ovens such as resistance heating and infrared heating remove (or retain) the original heating equipment in the oven, and replace the original heating equipment in the oven. Install multiple sets of resistance wires or far-infrared carbon fiber electric heating tubes in the heating room and the flue-cured tobacco room, and adjust the temperature in the barn by controlling different combinations of multiple sets of resistance wires or far-infrared carbon fiber electric heating tubes. Although the control is relatively simple, no matter the resistance wire Or far-infrared carbon fiber electric heating tubes have low heating efficiency and output power can only be controlled in sections, resulting in the problem that the temperature adjustment is not fine and stable enough
