The invention is suitable for the field of drying equipment, and particularly relates to an external dehumidification type heat pump dryer. The external dehumidification type heat pump dryer comprisesa drying system and a dehumidification system which communicate with each other, the dehumidification system cools and dehumidifies fed gas to obtain low-temperature and low-humidity gas, the low-temperature and low-humidity gas is preheated and then guided into the drying system, the drying system heats preheated low-temperature and low-humidity gas to obtain high-temperature and low-humidity gas, the high-temperature and low-humidity gas is pumped into the dehumidification system for heat exchange to avoid heat loss and for low-temperature dehumidification after being used for completing drying, heat exchange is performed to avoid heat loss to control the power of an outer fan to control a heat exchange rate for balance, so that heating by high-power heating wires is replaced, the problems that an open type heat pump drying technology is poor in environment applicability, and a closed type heat pump drying technology is high in energy consumption, high in cost and difficult to popularize are solved, the drying system can be quickly updated, the external dehumidification type heat pump dryer can be suitable for most existing drying chambers, and the blank of the heat pump dryingtechnology is filled.
Description
technical field [0001] The invention relates to the field of drying equipment, in particular to an external dehumidification heat pump dryer. Background technique [0002] Drying is an indispensable process in many industrial productions and agricultural and sideline products processing. As a high-energy-consuming operation, material drying has a huge market capacity. With the intensification of energy consumption, there has been a gradual macro-control of energy utilization, vigorously promoting the use of new energy equipment, safe and environmentally friendly, low-carbon and energy-saving heat pump drying equipment gradually replaces the original fuel, coal, electric heating and other high-energy The early drying equipment with high consumption and high pollution has become a dark horse in the drying industry. [0003] In the drying market, the drying rate of food, tea, medicinal materials and other products is relatively low, and the social demand is large. Nowadays, p...
