Embodiment Construction

[0040] The present invention will be further elaborated below in conjunction with specific embodiments.

[0041] Such as figure 1 As shown, a nitrogen source heat pump drying unit includes a drying box, a control system 21 and an outdoor condenser 20. The drying box includes a box body 1 and a heat pump room and a drying room arranged in the box body. A small pusher is placed in the drying room. The car 11 and the material tray 12 are characterized in that a horizontal baffle 5 is provided on the side close to the heat pump room in the drying chamber, and the baffle 5 divides the drying chamber into upper and lower air passages, and the material tray 12 is arranged in the lower part On the trolley 11 in the air passage, the upper and lower parts of the heat pump chamber are respectively provided with vents connected with the upper and lower air passages of the drying chamber;

[0042]A condenser 24 is installed on the upper part of the heat pump chamber, and an evaporator 15 ...

Abstract

The invention discloses a drying unit of a nitrogen-source heat pump, comprising a drying box, a control system and an outdoor condenser, wherein the drying box comprises a box body, a heat pump chamber and a drying chamber; and the heat pump chamber and the drying chamber are arranged in the box body. The drying unit forms drying gas adjusting equipment with a nitrogen source, heat-pump equipment and a nitrogen device form a nitrogen heat-pump combining device so as to construct a closed circulation loop which adopts nitrogen as a medium to dry materials and effectively control the content of nitrogen in the drying chamber; and high-viscosity glass cement is used for sealing internal and external gaps of a drying room, a ventilating channel is modified, and a baffle, an arc-shaped air guide plate and an air uniformizing plate are added to enable the gas drying medium to be uniformly distributed in the drying chamber under certain air speed. The drying unit disclosed by the invention has the beneficial effects that the heat pump and a nitrogen combining device are used, the advantages of no pollution and low energy consumption of the heat pump can be fully utilized, the materials are dried under the condition of adopting nitrogen as a drying medium, the oxidation of the materials is prevented, the nutritional ingredients of the materials are retained, and the quality of dried products is improved.

Description

technical field [0001] The invention relates to the field of drying devices, in particular to a nitrogen source heat pump drying unit. Background technique [0002] The scientific storage and processing of agricultural products can prolong the supply time, adjust the low and peak seasons of agricultural products, adjust the regional shortage, and realize the annual supply, so as to meet people's demand for food diversification and improve the nutritional level. According to reports, in developed countries, the output value of the agricultural product storage and processing industry is higher than that of agriculture, such as 3.7:1 in the UK, 2.7:1 in Japan, 2.6:1 in France, 2.0:1 in the United States, and only 0.4 in China: 1. Taking grain as an example, China's annual grain output is 40 million tons, and only 8% of it has been stored and processed. The total production value is 1:0.3, while that of developed countries is 1:4. The main reason for this situation is that the...
