Heat pump heat recovery walnut turning and drying device

Abstract

The invention discloses a heat pump type heat recovery walnut turning and drying device. There is a baffle-controlled sine wave humidity expander at the bell mouth of the left end of the air outlet bucket for heat preservation enclosure, and the distance between the baffle plate and the bell mouth of the left end of the air outlet bucket is automatically controlled by humidity. The outlet at the right end of the air outlet corresponds to the vapor-liquid coexistence coil area of ​​the external unit; there is a drying bar sieve body for placing walnuts in the heat preservation maintenance, and the sine wave thermal expansion and cold contraction device can drive the drying bar sieve body to rotate and tilt moderately. The temperature fluctuation of the present invention produces sine wave heat expansion and cold contraction telescopic tilting sieve plate combined with vibration to drive the continuous turning of the walnut drying process, which is beneficial to uniform and efficient drying; the sine wave humidity expander automatically controls the flow of moisture exhaust through the humidity control damper, which is particularly beneficial to improve drying. speed; the humidity outlet is aligned with the vapor-liquid coexistence coil area of ​​the external unit, which is particularly beneficial to the efficient recovery of tail heat and energy saving and efficiency; the design of the finned coil of the external unit is particularly beneficial to the efficient recovery of system tail heat, while reducing the power consumption of the compressor Very low.

Description

technical field [0001] The invention relates to a heat pump type heat recovery walnut tumbling drying device. Background technique [0002] Walnut, also known as walnut, Qiang peach, is a Juglandaceae plant. Together with almonds, cashew nuts and hazelnuts, it is also known as the world-renowned "four major dried fruits". Walnuts are rich in nutrients, containing 15-20 grams of protein per hectogram, more fat, and 10 grams of carbohydrates; Flavin and other vitamins are beneficial to the human body and can strengthen the brain. It is one of the nut foods loved by the people and is known as "longevity fruit" and "longevity fruit". [0003] Walnuts are known abroad as "Hercules food", "nutritious nuts" and "puzzle fruit"; Brain effect and rich nutritional value have been praised by more and more people. [0004] In order to facilitate preservation, fresh walnuts need to be dried. At this stage, there are mainly two types of artificial natural drying and dryer drying. Natu...

AI Technical Summary

Problems solved by technology

Natural drying is greatly affected by the weather and has low efficiency, which is not conducive to the industrialization of walnuts. Although the existing drying machine can achieve rapid drying, it also discharges a large amount of heat while dehumidifying, so the energy consumption is high. economically uneconomical
