A frequency conversion flue-cured tobacco heat pump dual power barn

Abstract

The invention discloses a frequency conversion flue-cured tobacco heat pump dual-power barn, which comprises a flue-cured tobacco room, a heating room, a heat pump unit, and a biomass fuel furnace. The return 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 directly opposite the vent, the heat exchange device is installed above the heat pump evaporator, and the diversion fan is installed above the heat exchange device. The heat pump condenser of the heat pump unit is arranged at the air inlet, 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 present invention realizes automatic control through a control device, can precisely control temperature changes, and has high heat utilization efficiency. Compared with other curing methods, the curing cost is low and energy-saving, and the loss of tobacco leaf curing modulation is reduced, and the yellowing of tobacco leaves is coordinated with color fixing. Drying is matched with aroma, and the goal of roasting tobacco leaves to be yellow, dry and fragrant is achieved.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing equipment, and in particular relates to a frequency conversion type flue-cured tobacco heat pump dual-power curing barn which 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 competit...

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
