Heat pump type heat recovery pistachio nut turning and drying device

Abstract

The invention discloses a heat pump type heat recovery pistachio nut turning and drying device. A baffle controlled sine wave humidity telescopic device is arranged at an air-out hopper left horn mouth of a thermal insulation enclosure; the distance between the baffle and the air-out hopper left horn mouth is automatically controlled by humidity; an air-out hopper right outlet is corresponding to a vapour-liquid coexistence coil area of an outer machine; a drying sieve body steel wire mesh for supportingpistachio nuts is arranged in the thermal insulation enclosure; a sine wave heat-expansion and cold-contraction device can drive the drying sieve body steel wire mesh to rotate and incline moderately. According to the heat pump type heat recovery pistachio nut turning and drying device disclosed by the invention, temperature fluctuation causes the sine wave heat-expansion and cold-contraction device to stretch and incline a sieve tray, so as to, in combination with vibration, drive pistachio nuts to turn continuously during the drying procedure; the device is in favor of drying pistachio nuts evenly and efficiently; the sine wave humidity telescopic device automatically controls discharged moisture flow through a humidity control air door, so that the drying efficiency is improved; a moisture discharging outlet aligns to the vapour-liquid coexistence coil area of the outer machine, so that tail heat is efficiently recycled; energy is saved and efficiency is increased; the fin coil of the outer machine is quite in favor of realizing efficient recycling of the system tail heat, and meanwhile the power consumption of a compressor is quite low.

Description

technical field [0001] The invention relates to a heat pump type heat recovery pistachio turning and drying device. Background technique [0002] Pistachio tree (Pistacia vera), also known as pistachio, is a small deciduous tree. Its fruit is a kind of dried fruit, commonly known as pistachio, also known as "nameless fruit". Pistachios are rich in vitamins, minerals and antioxidant elements. They are low in fat, low in calories and high in fiber, making them a wise choice for health. It is mainly produced in Syria, Iraq, Iran, the southwestern part of the former Soviet Union and southern Europe. It is also cultivated in Xinjiang, China. Pistachios are suitable for normal growth in this area, and have good economic benefits. At the same time, they can be used as an excellent soil and water conservation tree species. [0003] Pistachios are sweet and non-toxic, warming the kidneys and spleen, nourishing the deficiency, regulating the Qi, and can treat neurasthenia, edema, an...

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 pistachios. Although the existing drying machine can achieve fast drying, it also discharges a large amount of heat while dehumidifying, so the energy consumption is high. , it is not economical
