Air source heat pump type tobacco curing barn with auxiliary heat device

Abstract

The invention discloses an air source heat pump type tobacco curing barn with an auxiliary heat device. The air source heat pump type tobacco curing barn comprises a tobacco containing chamber and a heating chamber arranged at one end of the tobacco containing chamber, a heat exchanger is arranged on the upper portion of an inner cavity of the heating chamber, an axial flow fan is arranged in the middle of the inner cavity of the heating chamber, the heat exchanger is connected with an air source heat pump through a pipeline, and an electric heating device is arranged between the heat exchanger (3) and the axial flow fan. According to the air source heat pump type tobacco curing barn with the auxiliary heat device, the electric heating principle is adopted, the electric heating device is additionally arranged for auxiliary heat supply based on heat supply of the air source heat pump, and the baking temperature is ensured through auxiliary heat supply of the electric heating device while the heating working efficiency of the air source heat pump is utilized, so that tobacco leaf baking failures caused by the environment temperature factor are avoided, the safe baking of tobacco leaves is guaranteed, and meanwhile the baking quality of tobacco leaves can be easily improved.

Description

technical field [0001] The invention relates to a tobacco curing room, in particular to an air source heat pump type tobacco curing room with an auxiliary heating device, which belongs to the technical field of tobacco leaf curing equipment. Background technique [0002] Tobacco curing is an extremely important process in tobacco leaf production. The quality of curing directly determines the price of tobacco leaves and the taste of finished tobacco, and the equipment in the curing room is one of the most important factors determining the quality of tobacco leaf curing. Good baking equipment can not only bake better quality tobacco leaves, but also contribute to energy conservation and environmental protection. [0003] The air source heat pump barn is a barn equipment that is widely promoted at present. The existing air source heat pump barn realizes the heating demand of the barn through the air heat source pump. There are certain requirements. When the temperature is low,...

Problems solved by technology

[0003] The air source heat pump barn is a barn equipment that is widely promoted at present. The existing air source heat pump barn realizes the heating demand of the barn through the air heat source pump. There are certain requirements. When the temperature is low, the heating efficiency of the entire air heat source pump is low, and the baking temperature may not reach the set temperature, which is easy to cause the consequences of roasting the tobacco leaves.

Therefore, an air source heat pump type tobacco flue-curing room with an auxiliary heating device is provided to overcome the problem of baking failure caused by ambient temperature factors
