Description

Technical field: [0001] The invention relates to the field of heat pump drying equipment, in particular to the technical field of food processing equipment, and is especially suitable for drying vermicelli. Background technique: [0002] At present, air source heat pumps are mostly used for dry noodles. The heated air is sent into the drying room, and it is directly discharged in the form of waste gas after heat exchange with the noodles. However, the waste gas contains steam latent heat and high-temperature sensible heat, resulting in a lot of waste of energy. Moreover, the air source heat pump is greatly affected by the ambient temperature, which is not conducive to large-scale application across the country. [0003] As we all know, heat pump drying equipment is a special equipment for drying materials. The heat pump provides heat supply for the drying equipment, and sends the heated airflow into the drying chamber. The high-temperature dry airflow takes away the water va...

AI Technical Summary

Problems solved by technology

At present, the heat pump drying equipment is limited by the characteristics of the heat pump. In the lower ambient temperature, the heating capacity and energy efficiency ratio of the heat pump are relatively low. Because the drying process of the material is not affected by the season and the ambient temperature, the drying process will be carried out throughout the year, so in the selection Heat pumps are often matched according to the heat load at low ambient temperature. At this time, the selection of heat pump equipment will be large, which not only increases the initial investment of drying equipment, but also lowers the energy efficiency of heat pump drying equipment at low ambient temperature. Energy-saving advantages Weakened, and when the ambient temperature is high, the utilization rate of the heat pump equipment is very low

On the other hand, the hot and humid air discharged from the heat pump drying equipment is not effectively utilized, and most of the heat is discharged into the environment, resulting in waste of heat
