The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1-2 As shown, the utility model provides a technical solution of a tunnel type heat pump drying line: it includes a material channel 1, food to be dried is put into the material channel 1 for drying, closed doors are arranged on both sides of the material channel 1, the two closed doors are opened, and the staff transports the food to be dried into the material channel 1, and the material channel 1 can hold a large number of foods at one time, thereby improving the efficiency of drying food in the factory, and when drying, the staff closes the two closed doors.

[0022] In this embodiment, an air inlet 2 and an air outlet 3 are provided on the top surface of the material channel 1. The air inlet 2 and the air outlet 3 are symmetrically arranged and vertically opened. A heat exchanger 4 is provided on the top surface of the material channel 1 and is located directly above the air outlet 3. An upper air duct 5 is installed on the top surface of the material channel 1 to form a channel between the upper air duct 5 and the material channel 1. At the same time, an air delivery duct 6 is provided on the top surface of the material channel 1 and is located above the air inlet 2. The corners of the air delivery duct 6 are arranged in an arc shape to accelerate the passage of hot air. The fresh air enters the upper air duct 5 after being heated by the heat exchange, and then enters the air delivery duct 6 through the upper air duct 5, and then enters the material channel 1 through the air outlet 3 to dry the food.
