New instant Rice noodles/instant noodles air energy heat pump drying solution

Heat pump closed dehumidification dryer - a device that uses a refrigeration system to cool and dehumidify humid air, and uses the principle of a heat pump to recover the latent heat of moisture condensation in the humid air to heat the air. The basic principle is a combination of dehumidification (drying materials) and heat pump (energy recovery).
The difference between a closed-loop heat pump dehumidification dryer and a traditional hot air dryer is that the wet air circulation method is different. The former has a closed cycle of wet air between the oven and the dehumidification dryer (without emitting heat); The latter is an open system that uses a heat source to heat the air and discharge the hygroscopic wet air (while discharging a large amount of heat), with a low energy utilization rate of 20-50%.
Regenerative cycle: Add a regenerator in the system to reduce the temperature of the wet air entering the evaporator and increase the temperature of the wet air entering the condenser; The regenerative cycle reduces the cooling capacity of the evaporator used for air cooling (ineffective cooling consumption), while the cooling capacity used for dehumidification process increases. The ideal state is that the cooling capacity of the heat pump evaporator is fully used for dehumidification (the wet air entering the evaporator reaches the dew point temperature), and the heat pump closed dehumidification dryer that increases the regenerative cycle saves more than 30% energy compared to ordinary dehumidification dryers.
The dehumidification air volume and circulation air volume regulation technology pursue high thermal efficiency and even greater dehumidification capacity.
Principle of Rice noodles Heat Pump Dryer:
During the drying process of the heat pump, the air in the drying room and the unit undergoes a closed cycle. The high-temperature and high humidity return air in the drying room passes through a cold and heat recovery device, reaching the refrigeration system of the heat pump for cooling and dehumidification, and most of the condensed water is discharged. Then, it passes through the cold and heat recovery device again, causing the temperature of the wet air entering the refrigeration plate to decrease and the temperature of the cold air entering the heating plate to increase, thereby increasing the dehumidification amount. Compared to ordinary dehumidifiers, it saves more than 30% of energy, The dehumidified dry and cold air is pressurized by the fan and flows through the heating strip for heating, and then returns to the drying room to continue drying the materials. The water is taken away from the surface of Rice noodles and then continues the next cycle.
