Smoked fish drying device driven to rotate by sine wave thermal expansion

Abstract

The invention discloses a smoked fish drying device driven to rotate by sine wave thermal expansion. A water tank is arranged in a thermal insulation enclosure, and water is injected into the water tank and soak a spiral pipe A and a spiral pipe B in the water tank; a compressor A, the spiral pipe A, a capillary pipe A, an indoor unit of a refrigerating air conditioner and related pipes form a heat pump circulating dehumidification system A; an outdoor unit of a heating air conditioner, an indoor unit of the heating air conditioner, a capillary pipe B, the spiral pipe B and related pipes form a heat pump circulating heating system B; the system A and the system B work alternately to evaporate, condensate and discharge water of smoked fish in the thermal insulation enclosure and store and use heat in the water tank, a sine wave thermal expander connecting rack is arranged in the thermal insulation enclosure and is engaged with a pinion, and the pinion is connected with the smoked fish through a lifting hook. Compared with an existing gas-state moisture discharging and drying mode, the smoked fish drying device driven to rotate by sine wave thermal expansion has the advantages that energy consumption is greatly reduced, zero release of refrigerating and moisture removing heat can be realized, by a thermal expander, the smoked fish is changed at a rotating angle along with change of the temperature, hardening of the smoked fish is prevented, and drying and dehydrating are promoted.

Description

technical field [0001] The invention relates to a dried fish drying device driven by sine wave thermal expansion. Background technique [0002] Drying dried fish is essentially the process of discharging the water in the dried fish. However, almost all the existing drying equipment uses direct heating to discharge the water in the dried fish in the form of gaseous water. Because the enthalpy of gaseous water is much higher It is higher than liquid water and has a high temperature, so a large amount of energy is also discharged when gaseous water is discharged, which inevitably causes a large amount of heat energy loss, which is obviously not in line with my country's current energy-saving and emission-reduction policies. [0003] Secondly, most of the heating methods of existing drying equipment are direct heating, that is, direct heating by steam or electricity or heat transfer oil, but the thermal conversion efficiency of direct heating is low, and the thermal conversion ra...

Problems solved by technology

[0002] Drying dried fish is essentially the process of discharging the water in the dried fish. However, almost all the existing drying equipment uses direct heating to discharge the water in the dried fish in the form of gaseous water. Because the enthalpy of gaseous water is much higher It is higher than liquid water and has a high temperature, so gaseous water also discharges a large amount of energy, which inevitably causes a large amount of heat loss, which is obviously not in line with my country's current energy-saving and emission-reduction policies.

[0003] Secondly, most of the heating methods of existing drying equipment are direct heating, that is, direct heating by steam or electricity or heat transfer oil, but the thermal conversion efficiency of direct heating is low, and the thermal conversion rate of large boilers can only reach 90% The energy efficiency of heat pump heat transfer is relatively high, which can reach more than 3, which greatly improves the efficiency of heat energy utilization and realizes energy saving and emission reduction.

[0004] Thirdly, if the cured fish is placed densely, it is easy to harden during the drying process, which will hinder the evaporation of water and reduce the drying efficiency
