Heat pump type heat recovery salted fish drying device

Abstract

The invention discloses a heat pump type heat recovery salted fish drying device. A baffle controlled by sine wave moisture expansion pieces is arranged at a horn opening in the left end of an air discharge bucket of a heat insulation enclosure; the distance between the baffle and the horn opening in the left end of the air discharge bucket is automatically controlled by the moisture; an outlet in the right end of the air discharge bucket corresponds to a steam-liquid coexistence coil pipe region of an external unit; salted fishes are hung on a steel pipe in the heat insulation enclosure. According to the heat pump type heat recovery salted fish drying device, the temperature fluctuation causes expansion and contraction of a sine wave heat expansion and cold contraction device to automatically control the magnitude of the air volume, so that uniform and efficient drying is facilitated; the sine wave moisture expansion pieces automatically control the moisture discharge flow through a moisture control air door, and the operation is particularly favorable for improving the drying rate; a moisture discharge outlet is aligned to the steam-liquid coexistence coil pipe region of the external unit, so that efficient recovery of afterheat is particularly facilitated, and energy conservation and efficiency improvement are realized; the design of a finned coil pipe of the external unit is particularly favorable for realizing the efficient recovery of the afterheat of a system, and a compressor is extremely low in power consumption.

Description

technical field [0001] The invention relates to a heat pump type heat recovery salted fish drying device. Background technique [0002] Salted fish is fish that has been pickled in salt and dried in the sun. In the past, because there was no low-temperature preservation technology, fish was easy to rot, so fishermen along the coasts of the world used this method to preserve fish. In ancient China, salted fish was called "abalone", and there was an idiom "the place of abalone" (this is not the abalone that is now a rare seafood). Among the salted fish in Guangdong, Ma You is famous, which is a kind of Meixiang salted fish with a strong and special smell. Fried rice with salted fish and chicken cubes, a Cantonese special dish, is made in this way. [0003] In order to facilitate later preservation, it is necessary to dry fresh salted fish. At this stage, there are mainly two kinds of artificial natural drying and dryer drying. Natural drying is greatly affected by the weat...

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 salted fish. 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
