Abstract

The invention provides a heat pump drying device, and relates to the technical field of drying devices. The heat pump drying device comprises a material chamber, a separation partition, a heat recoverer, a heat pump, an auxiliary electric heater and a fresh air duct, wherein an air inlet of the material chamber is provided with an air supply duct; an air outlet of the material chamber is providedwith an air return duct; the separation partition is arranged in the air return duct and divides the air return duct into a first air duct and a second air duct; the fresh air duct communicates with the second air duct through the heat recoverer; the first air duct is connected with the heat pump through the heat recoverer; the auxiliary electric heater is mounted on the heat pump; and the secondair duct and the air supply duct are connected with the auxiliary electric heater through the heat pump. According to the heat pump drying device provided by the invention, the heat pump is a main heat supply element, the auxiliary electric heater helps supply heat, the separation partition divides the air return duct into the first air duct and the second air duct, air in the material chamber isdivided into two parts to be separately treated, and the utilization rate of heat and the moisture exhaust quantity in the material chamber are increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of drying devices, in particular to a heat pump drying device. Background technique [0002] Heat pump drying technology has been widely used and developed in the fields of agricultural and sideline product processing, wood drying, grain and food drying, etc. It is also popularized and applied in the roasting process. Among the many products to be baked, the tobacco leaf has a long time to bake, consumes a lot of heat, and has a high temperature (the highest temperature is about 70°C), which is obviously special compared to other products to be baked. In recent years, some heat pump products have been applied to tobacco leaf curing, but there are the following problems: the night temperature in some areas is low, the heat supply of heat pumps is insufficient, and it is difficult to reach the temperature required for curing; Some heat pump drying equipment has insufficient moisture...
