Description

Tobacco flue-curing house

Technical Field

The invention relates to the field of flue-cured tobacco, in particular to a tobacco curing house.

Background

Tobacco leaves are main projects for promoting the poverty alleviation of rural industries by governments at all levels in China, the tobacco leaf baking cost and quality are related to the economic benefit of tobacco growers, and the key for improving the tobacco leaf baking quality and reducing the baking cost lies in baking equipment and a baking method. For a long time, tobacco leaf baking equipment of tobacco growers is gradually changed into electric baking and biomass gasification combustion machines from an earthen coal furnace, the electric baking cost is high, and the profits of tobacco growers are reduced. The existing biomass combustion device has at least the following defects: (1) the burnt ash cannot be automatically removed, so that the potential safety hazard caused by the air passage blockage and tempering is easily caused; (2) the gasification combustion is incomplete, the heat energy benefit is not high, and substances such as tar which are not completely combusted can enter the heat supply pipeline and be coated on the inner wall of the heat supply pipeline, so that the baking effect and the tobacco leaf quality are influenced. According to statistics, 120 ten thousand seats of intensive tobacco curing houses built in China by 2017 are provided, wherein 99.9% of coal-fired tobacco curing houses are used, 350 ten thousand tons of coal are consumed in each year in baking, about 870 ten thousand tons of carbon dioxide, 21 ten thousand tons of sulfur dioxide, 3 ten thousand tons of nitrogen dioxide, 0.7 ten thousand tons of carbon monoxide (coal gas) and 3.5 ten thousand tons of dust are discharged in the combustion process, and a large amount of harmful gas is discharged to cause great pollution to the environment. Therefore, it is a problem to be solved to reduce the baking cost and environmental pollution.

Disclosure of Invention

The invention aims to provide a tobacco flue-curing house, which adopts air energy to generate heat energy to circularly cure tobacco leaves, can ensure the quality of the tobacco leaves and is beneficial to environmental protection.

To achieve the above object, the embodiments of the present invention are: a tobacco flue-curing house is provided with a heat supply device and a baking chamber, wherein the heat supply device is communicated with the heat supply chamber, and the heat supply chamber is communicated with the baking chamber; a backflow chamber is arranged above the heat supply chamber, the backflow chamber is communicated with the baking chamber, a through hole is formed between the backflow chamber and the heat supply chamber, and a fan is arranged at the through hole.

In an advantageous embodiment, the roasting chamber has a plurality of moisture evacuation openings.

As an optimized embodiment, the baking chamber has a viewing port.

As the optimized implementation mode, a temperature sensor and a tobacco curing frame are arranged in the baking chamber, and the temperature sensor is connected with a heat supply device.

As an optimized implementation mode, the heat supply device is a tobacco drying heat pump unit.

As an optimized embodiment, the heating device is connected with a controller.

The invention has the beneficial effects that:

(1) because the heating device is a tobacco drying heat pump unit, the tobacco leaf is dried by adopting heat energy generated by an air energy heat pump, the tobacco leaf drying device is clean and environment-friendly, and tar or harmful substances in fuel gas generated by gasification of biomass fuel or combustion of coal can be prevented from entering a tobacco curing room to influence the quality of flue-cured tobacco, thereby ensuring that the quality of the flue-cured tobacco leaf is improved.

(2) The heat supply room top is provided with the backward flow room, and the steam in the baking chamber gets into the backward flow room after, and the fan that the backward flow indoor setting was set up can blow into the heat supply room with the steam in the baking chamber in, then gets into the baking chamber again and toasts the tobacco leaf, so recycling, can reduce the energy consumption, toasts the cost.

(3) The air energy heat pump dryer is adopted to bake the tobacco leaves, so that the energy is saved, the operation is stable, the automatic and accurate control can be realized, and the time and the labor cost are greatly saved.
