Description

Technical Field

[0002] Heat pump dryer is a heat-raising device, which is mainly used in the drying and dehydration process of food, medicinal materials, wood, agricultural and sideline products, industrial products, etc. When squid is processed, it needs to be dried in a heat pump dryer to facilitate the storage and consumption of the squid. The heat pump dryer uses the reverse Carnot principle to absorb heat from the surrounding environment and transfer it to the heated object.

[0003] According to an energy-saving and environmentally friendly hot air circulation air energy heat pump dryer with publication number CN208536530U, it includes a heat pump dryer, an evaporator, a gas-liquid separator, a compressor and a throttle valve are arranged inside the heat pump dryer, and the evaporator, the gas-liquid separator and the compressor are fixedly connected to each other by copper pipes, a connecting pipe is arranged on one side of the heat pump dryer, one end of the connecting pipe is connected to a drying box, an external fan is arranged on one side of the heat pump dryer, and a dehumidification port is opened on the top of the heat pump dryer, and an electric control box and a fresh air valve are arranged on the front wall of the heat pump dryer. The utility model is provided with a guide plate at the air inlet of the drying box, and the guide plate is arranged upward and inclined. When the hot air enters the drying box from the air inlet, it will be evenly dispersed after being guided by the guide plate, so as to avoid the problem that the hot air enters the drying box unevenly and affects the drying effect.

[0004] The above patent mentions that the guide plate is set upward and inclined. When the hot air enters the drying box from the air inlet, it will be evenly dispersed after being guided by the guide plate, thereby avoiding the technical problem that the hot air enters the drying box unevenly and affects the drying effect. According to fluid mechanics analysis, the heated air expands and rises, while the cooled air sinks. The guide plate is set upward and inclined, so that the hot air rises rapidly after entering the drying chamber, and it is difficult to be evenly distributed in the drying chamber, causing the food on the tray to be heated unevenly, affecting the drying effect of the food on the tray.
