A humidification device for apple storage

Abstract

This utility model discloses a humidification device for apple storage, including a casing. A controller is installed on the left side of the outer wall of the casing, and a partition is fixedly connected to the middle of the casing. A micro-mist system is installed on the left side of the casing, and a dry fog system is installed on the right side. By incorporating both the dry fog and micro-mist systems, this utility model addresses the issue of rapid humidity reduction during periods of rising daytime temperatures. The dry fog system quickly increases humidity and suppresses evaporation, operating for 10-15 minutes to rapidly raise humidity. The micro-mist system then maintains humidity by oscillating and generating water mist of approximately 1-5 micrometers. This finer, more evenly distributed mist droplets are suitable for low wind speeds and sustained humidity maintenance. At night and in the early morning, the combination of low-speed micro-mist coverage and rapid dry fog penetration allows for coverage of distant, high-temperature areas, while the micro-mist is suitable for nearby, low-temperature areas. This improves humidity regulation within the storage space and slows down moisture loss and skin shriveling of the apples.

Description

Technical Field

[0001] This utility model relates to the field of apple storage technology, specifically to a humidification device for apple storage. Background Technology

[0002] Apples require high humidity levels during storage; suitable humidity helps reduce water evaporation, delay skin wrinkling, and slow flesh spoilage. Currently, most common apple storage humidification equipment uses dry fog systems. These systems primarily consist of a water tank, an air supply system, a spray pump, spray pipes, and nozzles. During operation, compressed air atomizes water into fine droplets with a diameter of less than 10 micrometers, which are then sprayed out at high speed through the nozzles to rapidly humidify the warehouse air.

[0003] However, currently common dry fog humidification equipment still has some shortcomings, such as:

[0004] Dry fog spray has a high spray speed and concentrated spray points, which can easily lead to excessively high local air humidity, causing condensation and problems such as condensation and rotting on apple skin. It is difficult to precisely control humidity changes in different locations or at different times, and it requires a high degree of water cleanliness. Once the pipeline or nozzle is blocked, maintenance is inconvenient.

[0005] Therefore, there is an urgent need for a humidification device for apple storage to solve the above-mentioned technical defects. Utility Model Content

[0006] The purpose of this invention is to provide a humidification device for apple storage, in order to solve the problems mentioned in the background art, such as poor controllability of humidity regulation in the storage space and easy condensation and rotting of apple skin.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a humidification device for apple storage, comprising a casing, a controller disposed on the left side of the outer wall of the casing, a partition fixedly connected to the middle of the casing, a micro-mist system disposed on the left side of the casing, and a dry fog system disposed on the right side of the casing; the micro-mist system includes a micro-mist water tank fixed to the lower left of the partition, multiple sets of ultrasonic energy plates distributed at the bottom of the micro-mist water tank, and a mist storage chamber installed above the micro-mist water tank, the mist storage chamber being connected to the micro-mist system. The water tanks are connected by micro-mist pipes. Fans are installed at the top, front and rear of the left outer wall of the casing. Each fan is connected to a mist storage chamber by a diverter pipe. The dry fog system includes a dry fog water tank fixed in the lower right of the partition. A compressed air source is installed above the dry fog water tank. An air compressor water pump set is fixed at the top of the compressed air source. A water supply pipe is connected between the compressed air source and the dry fog water tank. A dry fog nozzle is fixed at the output end of the air compressor water pump set and extends to the outside of the casing.

[0008] As a further technical solution of this utility model, the bottom end of the dry fog nozzle output port is connected to a dry fog nozzle, and multiple sets of dry fog nozzles are arranged at equal intervals.

[0009] As a further technical solution of this utility model, solenoid valves are installed at both the micro-mist pipe and the water supply pipe.

[0010] As a further technical solution of this utility model, the fan is provided in three sets, and the three sets of fans are started and stopped independently.

[0011] As a further technical solution of this utility model, the bottom end of the micro-mist water tank is connected to a micro-mist drinking water pipe, the bottom end of the dry fog water tank is connected to a dry fog water intake pipe, and the inlets of the micro-mist drinking water pipe and the dry fog water intake pipe are both equipped with movable door panels, which are mounted on the bottom front end of the chassis.

[0012] As a further technical solution of this utility model, filters are installed inside the movable door panels, and the filters are respectively assembled inside the micro-mist drinking water pipe and the dry fog water intake pipe, and filter elements are snapped into the filters.

[0013] As a further technical solution of this utility model, both the micro-mist pipe and the water supply pipe outlet are equipped with check valves.

[0014] As a further technical solution of this utility model, both the micro-mist water tank and the dry mist water tank are equipped with level gauges.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting up a micro-mist system and a dry fog system, during the period of rising daytime temperature, the humidity inside the warehouse drops rapidly. At this time, the dry fog system can quickly increase the humidity and suppress evaporation. When the humidity inside the warehouse drops suddenly, such as after ventilation or when a large number of fruits are newly stored, the dry fog system is run for 10 to 15 minutes to quickly increase the humidity, and then the micro-mist system is started to maintain it. The micro-mist system oscillates to produce water mist of about 1 to 5 micrometers. The mist droplets are finer and more evenly distributed, which is suitable for low wind speed and long-term humidity maintenance. At night and in the early morning, the combination of low-speed micro-mist coverage and rapid dry fog penetration can cover distant, high-temperature areas, while micro-mist is suitable for nearby, low-temperature areas, thereby improving the humidity regulation effect in the storage space and delaying the loss of apple moisture and the drying of the skin.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a humidification device for apple storage, comprising a casing 1, a controller 21 disposed on the left side of the outer wall of the casing 1, a partition 13 fixedly connected to the middle of the casing 1, and a micro-mist system disposed on the left side of the casing 1; the micro-mist system includes a micro-mist water tank 14 fixed to the lower left of the partition 13, and multiple sets of ultrasonic energy plates 15 distributed at the bottom of the micro-mist water tank 14, the ultrasonic energy plates 15 being model UMT-25KHZ, with built-in high-frequency oscillation chips, which atomize the water mist. The mist is converted into 1-5 micron fine mist. A mist storage chamber 18 is installed above the mist water tank 14. A mist pipe 16 connects the mist storage chamber 18 and the mist water tank 14. Fans 20 are installed on the top, front and rear of the left outer wall of the casing 1 to push the mist through the mist storage chamber 18 to diffuse into the warehouse. At the same time, it also helps air circulation and improves the overall humidity distribution efficiency. It can be matched with a controller 21 to realize time-sharing control or frequency conversion control. A diversion pipe 19 is connected between the fan 20 and the mist storage chamber 18.

[0023] Specifically, such as Figure 1 and Figure 3As shown, the micro-mist system consists of multiple sets of ultrasonic vibration plates 15 arranged at the bottom of the micro-mist water tank 14, which are used to atomize the stored water through high-frequency oscillation. The atomized water mist is transported to the mist storage chamber 18 through the micro-mist pipe 16, and then diffused to the left side of the warehouse under the action of the airflow of the fan 20 through the diversion pipe 19, forming a diffused humid environment. The micro-mist system oscillates to produce water mist of about 1 to 5 micrometers. The mist droplets are finer and more evenly distributed, which is suitable for low wind speed and long-term humidity maintenance. At night and in the early morning, the relative humidity in the warehouse is already high. Using the micro-mist system can replenish the humidity in a small and even way and maintain a relatively stable humidity.

[0024] A dry fog system is installed on the right side inside the chassis 1. The dry fog system includes a dry fog water tank 6 fixed in the lower right of the partition 13. A compressed air source 5 is installed above the dry fog water tank 6. The compressed air source 5 is a ZGA-1.5 / 8 type oil-cooled screw air compressor. An air compressor water pump group 4 is fixed at the top of the compressed air source 5. The air compressor water pump group 4 is an integrated water pump + air compressor pump combination system, model SC-15Q. A water supply pipe 7 is connected between the compressed air source 5 and the dry fog water tank 6. A dry fog nozzle 2 is fixed at the output end of the air compressor water pump group 4. The dry fog nozzle 2 extends to the outside of the chassis 1. Solenoid valves are installed at both the micro-mist pipe 16 and the water supply pipe 7. There are three sets of fans 20. The three sets of fans 20 can be started and stopped independently. The bottom of the output port of the dry fog nozzle 2 is connected to a dry fog nozzle 3. Multiple sets of dry fog nozzles 3 are arranged at equal intervals.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the dry fog system's water tank 6 delivers water to the air compressor water pump group 4 through the water inlet pipe 7. Under high pressure, the water is sent into the dry fog nozzle 2, and then sprayed out through the nozzle 3 as fine mist droplets, forming a high-speed dry fog flow to quickly humidify the air. The dry fog system controls the water mist particle size to below 10 micrometers through high-pressure airflow. The fine droplets and fast spray speed make it suitable for rapid cooling and wide-area diffusion. During the period of rising daytime temperature, the humidity in the warehouse drops rapidly. At this time, using the dry fog system can quickly increase the humidity and suppress evaporation. When the humidity in the warehouse drops suddenly, such as after ventilation or when a large number of new fruits are put into storage, the dry fog system should be run for 10 to 15 minutes to quickly increase the humidity, and then the micro-fog system should be started to maintain the humidity.

[0026] Check valves are installed at the outlets of the micro-mist pipe 16 and the water supply pipe 7. Liquid level gauges 17 are installed in both the micro-mist water tank 14 and the dry mist water tank 6. The liquid level gauge 17 is an E2K-C25ME1 capacitive liquid level sensor.

[0027] Specifically, such as Figure 1 and Figure 3As shown, a level gauge 17 is installed inside both the micro-mist water tank 14 and the dry fog water tank 6 to monitor the water level in the tank in real time. When the water level drops to the set threshold, the controller 21 receives the level signal and issues a water replenishment command, automatically driving the external water source to replenish the water in the corresponding water tank through the micro-mist drinking water pipe 12 and the dry fog water intake pipe 8, ensuring a continuous water supply during long-term system operation, and avoiding the ultrasonic vibration energy sheet 15 from burning dry or the air compressor water pump group 4 from running dry due to low water level, without the need for manual water replenishment.

[0028] The bottom of the micro-mist water tank 14 is connected to the micro-mist drinking water pipe 12, and the bottom of the dry fog water tank 6 is connected to the dry fog water inlet pipe 8. Movable door panels 11 are installed at the inlets of both the micro-mist drinking water pipe 12 and the dry fog water inlet pipe 8. The movable door panels 11 are assembled at the bottom front end of the chassis 1. Filters 9 are installed inside the movable door panels 11. Filters 9 are respectively assembled inside the micro-mist drinking water pipe 12 and the dry fog water inlet pipe 8. Filter elements 10 are snapped into the filters 9.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, both the micro-mist drinking water pipe 12 and the dry fog water supply pipe 8 are connected to a movable door plate 11 installed at the bottom front of the casing 1. The door plate 11 is fitted with a filter 9, and the filter element 10 can be replaced inside the filter 9. The movable door plate 11 can be opened periodically to remove the filter element 10 for cleaning or replacement, preventing particulate impurities in the water source from entering the micro-mist pipe 16 or the dry fog nozzle 3 and causing blockage, thus ensuring that the spraying effect remains stable and uniform for a long time.

[0030] Working Principle: This equipment coordinates the micro-mist system and the dry fog system through the controller 21 to achieve dynamic humidity regulation of the apple storage environment. Multiple ultrasonic energy plates at the bottom of the micro-mist water tank 14 atomize the water source into fine mist of 1-5 microns, which is then sent into the mist storage chamber 18 through the micro-mist pipe 16 and blown out by multiple fans 20 through the diversion pipe 19, spreading to all directions of the warehouse to form a large-scale, uniformly humid environment. In the dry fog system, the dry fog water tank 6 supplies water to the air compressor water pump group 4 through the water inlet pipe 7. After being pressurized by the compressed air source 5, the water is sent into the dry fog spray pipe 2, and then sprayed out through multiple dry fog nozzles 3. High-speed droplets smaller than 10 micrometers are used to quickly increase air humidity. Solenoid valves are installed on both the micro-mist pipe 16 and the water supply pipe 7 to realize start and stop control. Liquid level gauges 17 are installed in the micro-mist water tank 14 and the dry fog water tank 6 to monitor the water level in real time. When the water level is lower than the set threshold, the controller 21 issues a water replenishment command to control the water replenishment to be injected through the micro-mist drinking water pipe 12 and the dry fog water inlet pipe 8. Movable door panels 11 are installed at the inlet of the two pipes. Filters 9 and removable filter elements 10 are installed in the door panels 11 to purify the water source, prevent the micro-mist pipe 16 or the dry fog nozzle 3 from being blocked, and ensure the continuous and stable spraying effect.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
