Description
Technical Field
[0001] This utility model relates to the field of malt processing technology, and in particular to a heat exchanger humidification device. Background Technology
[0002] One crucial process in beer brewing is the preparation and drying of malt. As the foundational ingredient in beer brewing, malt processing is extremely detailed; proper handling is essential for the next stage of brewing. In the malt drying stage, outdoor natural air is drawn in by an exhaust fan and passed through a steam heat exchanger to obtain high-temperature, dry air to dry the moist malt. The germinated malt is then transferred from the germination chamber to the drying chamber, a 29.9-meter diameter cylindrical chamber divided into upper and lower sections. The upper section has malt laid flat, while the lower section is circulated with hot air. During drying, the temperature, humidity, and time of the hot air are carefully controlled. A screw conveyor is used to turn the malt over at specific intervals to increase airflow, thus achieving the drying and maturation of the raw malt.
[0003] However, existing drying technologies often fail in winter due to the dry outdoor air and the increased temperature after steam heat exchangers, resulting in excessively dry malt. This affects color and makes the malt prone to re-drying after drying. Furthermore, producing malt with higher color intensity often requires high-temperature, humidified hot air. Current hot air technology only regulates temperature, not humidity. In dry winters, when the process requires humidified hot air, technicians often need to repeatedly enter the air chamber to pour water onto the floor. While the exhaust fan draws the air from the chamber under the drying chamber, the evaporation from the floor increases humidity to some extent. However, this requires multiple entries and exits to add water for each batch of malt, especially when the drying temperature reaches 65-86°C. This process is cumbersome, the produced hot air lacks the required humidity, and manual humidification is ineffective, difficult to control, and poses safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a heat exchanger humidification device to solve the problem that existing technologies require manual entry into the air chamber to add water to increase the humidity of hot air, which poses a safety hazard. The heat exchanger humidification device of this invention achieves humidification without the need for personnel to enter the high-temperature air chamber, which reduces the workload of personnel, eliminates safety hazards, protects personal safety, and also provides more precise humidity control.
[0005] This utility model provides a heat exchanger humidification device, including a heat exchange component, a humidification component, and a hot air chamber.

The humidification port of the humidification component is positioned facing the hot air chamber and can provide water mist into the hot air chamber through the vent. Fresh air flows sequentially through the heat exchange component, the humidification component, and the hot air chamber.

In use, the heat exchanger humidification device of this utility model forms hot air after passing through the heat exchange component.

The mixed hot air with a certain humidity then flows to the bottom of the drying chamber, achieving the drying of the wet malt on the upper layer of the drying chamber while ensuring the required color for the process. By mixing water vapor and water mist generated by the humidification component with the high-temperature air, the purpose of humidifying the high-temperature air is achieved, producing high-temperature, high-humidity air to meet the process requirements. During drying, the hot air can be humidified according to process requirements.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0024] Example 1:
[0025] This embodiment provides a heat exchanger humidification device, such as... Figures 1-4 As shown, the system includes a heat exchange assembly 1, a humidification assembly 2, and a hot air chamber 3. The humidification assembly 2 is positioned between the heat exchange assembly 1 and the hot air chamber 3. The humidification assembly 2 is positioned directly opposite the ventilation openings of the heat exchange assembly 1 and the hot air chamber 3. The heat exchange assembly 1 can be a steam heat exchanger, which exchanges heat with the fresh air passing laterally through the heat exchanger by introducing steam into the heat exchanger, thereby increasing the temperature of the fresh air. Specifically, a steam valve 11 is provided at the steam inlet of the steam heat exchanger to regulate the steam flow rate, thereby adjusting the heating rate of the fresh air.
[0026] A vent is provided on the side of the hot air chamber 3 facing the humidification component. The humidification port of the humidification component 2 is positioned facing the hot air chamber 3 and can provide water mist into the hot air chamber 3 through the vent. Fresh air flows sequentially through the heat exchange component 1, the humidification component 2 and the hot air chamber 3.
[0027] When using the heat exchanger humidification device in this embodiment, such as Figure 1As shown, fresh air flows from left to right. After passing through the heat exchange component 1, the fresh air becomes hot air. The hot air mixes with the water mist sprayed by the humidification component 2 in the hot air chamber 3 after passing through the vent. The hot air with a certain humidity then goes to the bottom of the drying box, thus drying the wet malt on the upper layer of the drying box while ensuring the color required by the process.
[0028] In this embodiment, the heat exchanger humidification device generates water vapor and mist through the humidification component 2, which mixes with the high-temperature air to humidify the air, producing high-temperature, high-humidity air to meet the process requirements. During drying, the hot air can be humidified according to process needs. Humidification can be achieved without personnel entering the high-temperature air chamber, reducing workload, eliminating safety hazards, protecting personal safety, and providing more precise humidity control.
[0029] In a preferred embodiment, the humidification assembly 2 includes a water distribution pipe 22 and multiple nozzles 23 arranged on the water distribution pipe 22. A regulating valve 21 is provided at the water inlet end of the water distribution pipe 22. The spray direction of the nozzles 23 is consistent with the airflow direction, and the nozzles 23 are fan-shaped nozzles, capable of spraying a uniform water mist into the hot air chamber 3. The regulating valve 21 can adjust the water volume to regulate the humidity of the hot air.
[0030] After the fresh air is heated and humidified by the steam heat exchanger and humidification component 2, it becomes high-temperature and high-humidity hot air, which is stored in the hot air chamber 3.
[0031] As a preferred embodiment, such as Figure 2 As shown, the water distribution pipe 22 includes multiple vertical pipes 24, a first horizontal pipe 25, and a second horizontal pipe 26. The multiple vertical pipes 24 are spaced apart, with their top ends connected to the first horizontal pipe 25 and their bottom ends connected to the second horizontal pipe 26. Multiple nozzles 23 are evenly distributed on the multiple vertical pipes 24. The water distribution pipe 22 is a galvanized pipe, which has good corrosion resistance. There can be 3 or 4 vertical pipes 24. The multiple vertical pipes 24, the first horizontal pipe 25, and the second horizontal pipe 26 are connected to form a rectangular frame-shaped water distribution pipe 22, which is directly opposite the ventilation openings of the heat exchange component 1 and the hot air chamber 3. The multiple nozzles 23 can evenly spray water mist into the hot air chamber 3, allowing the water mist to mix with the high-temperature fresh air to form high-temperature and high-humidity hot air.
[0032] In one preferred embodiment, the first transverse pipe 25 is connected to the water inlet pipe 27, and a high-pressure water pump is installed on the water inlet pipe 27. The water inlet pipe 27 is a 20mm stainless steel pipe.
[0033] In this embodiment, water is delivered to the inlet pipe 27, the first horizontal pipe 25 and multiple vertical pipes 24 by a high-pressure water pump and sprayed out through multiple nozzles 23.
[0034] In one preferred embodiment, the second transverse pipe 26 is connected to the drain pipe 28, and a drain valve 29 is provided on the drain pipe 28.
[0035] In this embodiment, by providing a drain valve 29 on the drain pipe 28, water in the water distribution pipe 22 can be discharged when the drain valve 29 is opened, so as to clean and discharge dirt in the water distribution pipe 22.
[0036] In a preferred embodiment, the water distribution pipe 22 is spaced 5cm-15cm from the heat exchange component 1. Preferably, the water distribution pipe 22 is spaced 10cm from the heat exchange component 1, allowing the blown hot air to flow sufficiently through the water distribution pipe 22.
[0037] In one preferred embodiment, the side of the hot air chamber 3 away from the humidification component 2 is connected to an air duct 4, an exhaust fan 5 is installed on the air duct 4, and the other end of the air duct 4 is connected to the bottom of the drying oven.
[0038] In this embodiment, the high-temperature and high-humidity hot air mixed in the hot air chamber 3 is sent to the bottom of the drying box through the air duct 4 by the exhaust fan 5, and is used to dry the malt on the screen of the drying box.
[0039] As a preferred embodiment, the air duct 4 is located on the lower side of the hot air chamber 3 to fully transmit the high-temperature and high-humidity hot air out of the hot air chamber 3.
[0040] In this embodiment, the heat exchanger humidification device places the humidification component 2 between the heat exchange component 1 and the hot air chamber 3. Tap water is supplied through a φ20mm stainless steel pipe, and a regulating valve 21 is installed on the water inlet pipe 27 to regulate the water volume, thereby adjusting the humidity of the high-temperature hot air. Finally, the tap water is atomized into water vapor and mist by nozzles 23. The nozzles 23 are set 10cm apart from the heat exchange component 1 and are oriented in the same direction as the hot air. The water vapor and mist generated by the nozzles 23 are mixed with the hot air and stored in the hot air chamber 3. After being extracted by the exhaust fan 5, they are sent to the bottom of the drying chamber through the air duct 4, thus drying the wet malt on the upper layer of the drying chamber while ensuring the required color for the process.
[0041] The heat exchanger humidification device in this embodiment has a simple structure and low cost. When high temperature and high humidity are required in the final stage of drying, the high-pressure water pump is started, and the opening is adjusted by regulating valve 21 to control the spray size of the fan-shaped nozzle. It is easy to operate and highly controllable, avoiding the need for manual watering in the hot air chamber, and also eliminating safety hazards and protecting personal safety.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
