Abstract

The invention discloses a heat pump drying device with multiple operation modes. The heat pump drying device comprises a heat pump circulating system and a drying medium processing channel; the heat pump circulating system is composed of a compressor, a condenser, an expansion valve and an evaporator, and the compressor is a combination of a single or multiple frequency-conversion compressor bodies; and the drying medium processing channel is subjected to combined control by four ventilation doors to form four change modes, namely a rapidly heating mode, a closed type mode, an open type mode and a semi-open type mode, and four different types of drying modes are formed. The heat pump drying device is high in dehumidification capacity, different operation modes can be provided targeted to different climate conditioners and diversity of drying objects, and the quality of a dried product is effectively improved, and energy is saved.

Description

technical field [0001] The invention relates to the application field of refrigeration heat pump technology, in particular to an intelligent heat pump drying device. Background technique [0002] Drying is an important process in the production process of industry, agricultural and sideline products and food processing industries. The drying process is a process of high energy consumption. The drying device and its drying process control and the quality of the dried processed products include: color, aroma, taste, shelf life, Nutrients, etc. are closely related, and are also closely related to production efficiency, cost, energy consumption, etc. [0003] Heat pump drying uses vapor compression refrigeration technology to absorb heat energy from air or other waste heat resources. The thermal efficiency is more than three times that of electric heating. There is no pollutant emission during the heating and drying process. The production process is clean and safe, and it is di...
