Description

Technical Field

[0001] The utility model relates to an air energy saving device for noodles in a drying room, belonging to the field of energy saving and environmental protection. Background Art

[0002] At present, noodle drying rooms generally use convection thermal drying method, which uses heat source to heat the air in the drying room, and uses wind power to convect the hot air to heat the wet noodles and take away the moisture in the wet noodles. The hot air becomes the drying medium, and even the heat carrier is also the moisture carrier. Noodle products need heat and rely on heat for heat and moisture exchange. After the wet noodles absorb the heat, they vaporize their own moisture and discharge it to achieve the drying purpose.

[0003] The method of controlling the drying room temperature is adopted to achieve the purpose of controlling the evaporation rate of water in the noodles. It can save heat energy, improve the working environment of workers, and does not require strict attention to heat preservation and moisture retention. The production process is easy to control and the production efficiency is high.

[0004] At present, there are two types of noodle drying rooms, namely steam thermal drying room and hot water thermal drying room according to the different heat sources.

[0005] The disadvantages of using steam as a heat source are:

[0006] (1) Steam is expensive as a heat source; (2) Steam as a heat source will eventually produce a large amount of high-temperature condensed water. If there is only one production line, it will not be able to be used, resulting in a large amount of heat loss, which will inevitably increase production costs; (3) Steam is not easy to obtain as a heat source; (4) The heat inside the drying room is discharged with the high-temperature and humid air, resulting in a large amount of heat loss. It is necessary to continuously provide heat to maintain the temperature inside the drying room;

[0007] The disadvantages of using hot water as a heat source are:

[0008] (1) Obtaining hot water for heating the medium requires expensive and complex heating equipment;

[0009] The heat inside the drying room causes a large amount of heat loss after being discharged with the high-temperature and humid air. Heat needs to be continuously supplied to maintain the internal temperature of the drying room. Utility Model Content

[0050] 1) The high-temperature and high-humidity gas in the drying room passes through the thermal evaporator. The refrigerant in the thermal evaporator absorbs heat and vaporizes. It runs to the main unit through the copper tube and passes through the main unit compressor, so that the low-temperature heat carried by the refrigerant is converted into high-temperature heat. The medium reaches the main unit through the PPR parallel water pipeline and is heated by the converted high-temperature heat.

[0051] 2) The high temperature and high humidity in the drying room passes through the evaporators of multiple hot water units and finally the evaporator of the hot air unit. The refrigerant in the evaporator absorbs heat and vaporizes, and runs to the main unit through the copper pipe. After passing through the main unit compressor, the low-temperature heat carried by the refrigerant is converted into high-temperature heat, and the high-temperature and high-humidity gas is heated to become low-temperature and low-humidity gas, making it a high-temperature and low-humidity gas, which re-enters the drying room through the air intake and exhaust system to replenish air for each room in the drying room.

[0052] When starting in summer, the heat recovery box absorbs outside air and extracts heat through the evaporator of the hot water unit in the heat pump mechanism. After starting, the heat carried by the high-temperature high-chamber gas in the drying room of the drying room is recovered to heat the water in the hot water main unit, and then the water is injected into the water tank through the PPR parallel bridge. The water pump draws the water out of the water tank and enters the drying room through the circulation bridge. The water entering the drying room dissipates heat in the drying room and then enters each hot water main unit for heating and temperature rise.

[0053] The medium hot water enters the drying room through the circulation bridge. After the water entering the drying room is cooled by the finned tube heat dissipation mechanism, it leaves the drying room and enters each hot water main unit for heating and temperature increase.

[0054] The noodles enter the drying room and move in each drying room under the action of the moving mechanism. The hot air stirring system blows the heat carried by the finned tube heat dissipation system evenly to the noodles. After the wet noodles absorb the heat, they vaporize their own moisture and discharge it. The gas carrying high temperature and high humidity enters the heat recovery box through the air intake and exhaust system (exhaust). The gas treated by the heat recovery box and the heat pump unit mechanism enters the drying rooms of the drying room through the air intake and exhaust system (intake).
