Description

Technical Field

[0001] This invention relates to the field of food storage technology, and in particular to a storage box and storage method for preparing rock sugar. Background Technology

[0002] Rock sugar is a crystalline food made from white sugar through processes such as re-dissolving, purification, and recrystallization. It has the physical properties of being highly hygroscopic and easily melting when heated. During industrial mass production, freshly made rock sugar still has a small amount of moisture remaining on its surface and inside, so it needs to be stored and transported in a timely manner.

[0003] Currently, the rock sugar production industry generally uses closed storage boxes and sealed storage tanks to store rock sugar. Publication number CN207618303U discloses a storage device for single-crystal rock sugar production, which includes an insulated cover and a rotating rod. Fixing pins are installed on both sides of the insulated cover, and a box body is movably connected to the bottom of the insulated cover. Condensation chambers are fixed on both sides of the box body, and condensers are installed inside the condensation chambers. A blower is connected to the top of the condensation chambers via an air inlet pipe, and the blower is connected to a three-way pipe via the air inlet pipe. Stirring blades are fixed at both ends of the rotating rod, and a ventilation pipe is installed on the rotating rod. An air outlet is provided at the top of the ventilation pipe. A sealing ring is embedded inside the bottom surface of the insulated cover, and a condensing pipe is installed on the bottom surface of the sealing ring. A gear reduction motor is connected to the bottom of the box body, and a door is hinged to the surface of the box body. Existing conventional rock sugar storage equipment mostly adopts a fully sealed structure design, which can achieve the basic effect of preventing dust and external moisture intrusion. However, there are still significant technical defects in practical applications: First, the air inside the existing sealed storage equipment is completely closed and cannot form circulation. The rock sugar that has just been produced cannot be naturally dried and dehumidified in the storage box. An additional independent drying process must be added. The rock sugar is loaded into the storage equipment for transfer after it has been dried offline to meet the standards. The process is cumbersome and lengthy, which seriously slows down the rock sugar transfer rhythm and greatly reduces the production turnover efficiency of the entire production line. Secondly, in a sealed storage environment, the internal moisture released by the rock sugar itself cannot escape. The moisture easily condenses into water droplets on the inner wall of the storage box. The accumulated moisture will cause the rock sugar close to the inner wall of the storage box to become damp, soften, and partially melt, and then stick to the inner wall of the box. This not only causes the loss of finished rock sugar, but also increases the workload of cleaning the box and sorting out defective rock sugar.

[0004] Third, traditional sealed storage boxes lack active dehumidification and ventilation control structures, making it impossible to regulate the temperature and humidity inside the box in real time. Long-term retention of moisture can easily cause rock sugar to clump, become damp and deteriorate, shortening the shelf life of rock sugar and making it difficult to meet the needs of industrial continuous production, efficient storage and long-distance transportation.

[0005] Therefore, a new type of storage box for preparing rock sugar can be used to overcome the shortcomings of the existing technology. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a storage box and storage method for preparing rock sugar.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A storage box for preparing rock sugar includes a storage box and a sealing cover hinged to the upper opening of the storage box; The bottom of the storage box is fixedly installed with several feet, and the sealing cover has multiple slots that cooperate with the corresponding feet (the feet cooperate with the slots for stacking the storage boxes). The sealing cover has an observation window, the inside of the sealing cover is a hollow cavity structure, and the sealing cover has an air inlet that connects the cavity to the outside. The storage box contains a water storage tank and a blower assembly. The water storage tank is connected to the outside through an air inlet pipe. The blower assembly includes a filter frame, filter cotton and a blower fan. The filter frame has filter cotton inside and fits the air inlet end of the blower fan. An arc-shaped air duct is fixed inside the cavity of the sealing cover. The lower end of the arc-shaped air duct is connected to the air outlet assembly. The air outlet assembly includes an air outlet box, an air guide mechanism, and a dehumidification box. The dehumidification box has several metal moisture collection plates arranged in an array at an angle. Air outlet holes are evenly opened at the bottom of the dehumidification box. Two sets of baffles are rotatably installed inside the air outlet box and equipped with spring coils. A rubber plate is fixed to the inner wall of the air outlet box. Several air outlet pipes and one-way pipes are connected to the bottom of the air outlet box. A convergent deflector is movably installed in the air guide mechanism. A water guide pipe passes through the sealing cover and is arranged around the cavity and the outside of the dehumidification box.

[0008] Preferably, the feet are evenly fixed at the four corners of the lower surface of the storage box. The feet are made of non-slip, wear-resistant hard rubber. The storage box has a square box structure with an open top. The size of the sealing cover matches the open top of the storage box. One side of the sealing cover is hinged to the upper side of the storage box via a hinge. When the sealing cover is closed, it completely covers the open top of the storage box and forms a limiting seal. The slot is located in the middle of the outer wall of the storage box. The slot cooperates with the external fixing buckle to lock and fix the sealing cover after it is closed. The observation window is made of transparent tempered glass and is embedded in the reserved window on the side wall of the sealing cover. The connection between the observation window and the sealing cover is sealed and waterproofed, allowing real-time observation of the rock sugar storage status inside the storage box. The water inlet is vertically located on the top wall of the sealing cover and is connected to the internal water storage tank. The water inlet port is equipped with a sealing plug to prevent external dust and moisture from entering the water storage tank during daily sealing.

[0009] Preferably, the water storage tank is fixedly embedded in one cavity inside the sealing cover. The water storage tank is a closed cavity structure. The top of the water storage tank is connected to the water inlet, and one end of the air inlet pipe is connected to the side wall of the water storage tank. The other end of the air inlet pipe extends to the outside of the sealing cover and communicates with the outside air. The connection between the air inlet pipe and the water storage tank is sealed and bonded. The blower assembly is fixedly fixed in the cavity of the sealing cover next to the water storage tank. The filter frame is a frame-type hollow structure fixed to the air inlet end of the blower fan. The filter cotton is detachably snapped into the hollow area inside the filter frame. The blower fan is fixedly installed on the inner wall of the cavity of the sealing cover with the air inlet end facing the air outlet side of the water storage tank. The air outlet end of the blower fan is connected to the inner cavity of the sealing cover, which can draw the air filtered by the water in the water storage tank into the cavity of the sealing cover for circulation.

[0010] Preferably, multiple sets of arc-shaped air ducts are fixedly installed at the bottom of the inner cavity of the sealing cover. The upper end of the arc-shaped air duct is connected to the inside of the sealing cover cavity, and the lower end of the arc-shaped air duct extends vertically downward and faces the upper opening of the air outlet box. When the sealing cover is fully closed, the lower end of the arc-shaped air duct presses against the baffle, causing it to rotate around the pivot and open. The baffles are symmetrically installed in pairs on both sides of the upper opening of the air outlet box. A spring coil is fitted between the baffle and the pivot of the air outlet box. Under normal conditions, the spring coil drives the two baffles to close in opposite directions and block the upper opening of the air outlet box. After the arc-shaped air duct separates from the baffle, the spring coil automatically resets to achieve the blockage, preventing the moisture inside the storage box from flowing back into the sealing cover cavity and the air duct.

[0011] Preferably, the dehumidifier box is fixedly installed inside the air outlet box at the upper middle position. The dehumidifier box has a rectangular hollow box structure and is fixedly connected to the inner wall of the air outlet box on all four sides. Several moisture collection plates are arranged at equal intervals and inclined from top to bottom inside the dehumidifier box. The two ends of the moisture collection plates are fixed to the left and right inner walls of the dehumidifier box and are inclined downward as a whole. The moisture collection plates are integrally formed with a metal heat-conducting material. Several through-type air outlet holes are evenly opened on the bottom wall of the dehumidifier box. The air outlet holes connect the inner cavity of the dehumidifier box with the inner cavity of the lower air outlet box. The water guide pipe is fixedly attached to the outer wall of the dehumidifier box and the inner wall of the sealing cover cavity in a meandering coil. The two ends of the water guide pipe extend to the outside of the sealing cover and can be connected to external cooling or heating equipment to realize the cooling or heating control of the circulating air.

[0012] Preferably, the rubber plate is fixedly bonded to the inner side wall of the air outlet box at the installation position corresponding to the dehumidifier box. The rubber plate is made of elastic soft rubber and elastically abuts against the side wall of the dehumidifier box. When the dehumidifier box vibrates due to air resistance, it relies on the rubber plate to provide elastic reset support, while buffering the vibration amplitude to avoid rigid collision damage to the components. The surface of the moisture collection plate 25 is smooth and the tilt angle is set to 15° to 30°, which facilitates the natural sliding and collection of water droplets condensed in the air along the plate surface, preventing the condensed water droplets from dripping directly onto the surface of the rock sugar below and causing it to become damp and melt. The dehumidifier box and the air outlet box are fixed with a gap fit, leaving a small vibration space to ensure the air turbulence effect.

[0013] Preferably, the air guide mechanism is fixedly installed inside the lower side of the air outlet box. Multiple sets of paddles are movably installed in a vertical array inside the air guide mechanism. The paddles adopt a streamlined structure that is narrow in the middle and wide at both ends. The two ends of the paddles are movably hinged to the inner wall of the air guide mechanism through thin shafts, and can freely swing and vibrate in a small amplitude under the blowing of airflow. The paddles form a narrow-diameter air duct structure between each pair, which can gather the airflow, increase the air velocity, and improve the air delivery penetration. Multiple vertically arranged air outlet pipes are evenly fixed and connected to the bottom wall of the air outlet box. The air outlet pipes are arranged in a matrix and their lower ends extend into the internal cavity of the storage box.

[0014] Preferably, the one-way pipes are interspersed between the air outlet pipes and fixed to the bottom wall of the air outlet box. The one-way pipes are equipped with one-way valve cores, which only allow the drying airflow to be sprayed out from the air outlet box into the storage box in one direction, preventing the humid air inside the storage box from flowing back. The lower end faces of the air outlet pipes and the one-way pipes are flush and both extend into the upper space of the inner cavity of the storage box. The connection between the air outlet pipes, the one-way pipes and the bottom wall of the air outlet box is sealed and fixed by welding, without gaps or air leakage, ensuring that the airflow is directed into the storage box to carry out all-round ventilation and drying treatment of the rock sugar.

[0015] Preferably, the filter frame is detachably clipped onto the outer frame of the blower fan inlet. The filter cotton is laid flat and embedded inside the filter frame, completely covering the ventilation area. This allows for secondary dust filtration and removal of some moisture from the air entering the blower fan. The rated water filling height inside the water storage tank is two-thirds of the cavity volume, with sufficient airflow buffer space reserved. The blower fan and water pipe are connected to external control switches and temperature control devices, which can start and stop the blower and switch between cooling and heating modes according to the ambient temperature and humidity. A ring-shaped sealing strip is provided on the mating end face of the sealing cover and the storage box to further improve the overall sealing performance after closure and prevent external moisture from entering the box.

[0016] The present invention also provides a method for storing rock sugar, including the above-mentioned storage box for rock sugar preparation, and further including the following steps: S1. Loading and Placement: The industrially prepared rock sugar is neatly filled into the storage box. After filling, the storage box is slightly vibrated to reduce the gap between the rock sugar particles and avoid the rock sugar from breaking during transportation. After filling, the sealing cover is rotated to close the top of the storage box and locked and fixed by the slot and the external buckle. S2. Water Pretreatment: Inject clean water into the water storage tank through the water inlet at the top of the sealed cover, controlling the water volume to occupy two-thirds of the water storage tank volume, and seal the water inlet port after filling. S3. Blower air intake and filtration: Start the blower fan. The blower fan will draw out the air inside the water storage tank to form a negative pressure. Outside air is drawn into the water storage tank through the air intake pipe. The air is washed with clean water in the water storage tank to remove particulate impurities. After being filtered a second time by the filter cotton in the filter frame, it is sent into the hollow cavity of the sealed cover. S4. Air duct opening and closing: When the sealed cover is closed, the lower end of the arc-shaped air duct presses against the baffle on the air outlet box to overcome the spring force and rotate to open, so that the air in the cavity of the sealed cover can be smoothly introduced into the dehumidification box through the arc-shaped air duct. S5. Low-temperature condensation dehumidification: After the air enters the dehumidification box, it comes into full contact with the array of tilted moisture collection plates. The low-temperature characteristics of the metal moisture collection plates cause water vapor in the air to condense and adhere. In the case of high external temperature environment, the air is cooled by external cooling equipment connected through water pipes, which further reduces the air temperature and improves the dehumidification effect. The dehumidification box is subjected to airflow resistance and elastic support of rubber plate to generate micro-vibration, which causes the condensed water droplets to slide down and be collected along the tilted moisture collection plates. S6. Turbulent airflow drying: The dehumidified air enters the air outlet box through the air outlet of the dehumidification box, and after being agitated and accelerated by the fins in the air guide mechanism, it is sprayed into the storage box in one direction through the air outlet pipe and the one-way pipe. The vibrating airflow and high-speed penetrating airflow are used to continuously ventilate and dehumidify the rock sugar, so as to achieve drying while storing. S7. Empty Box Residual Removal and Dehumidification: After the rock sugar in the storage box has been removed, the medium inside the pipe is heated by an external heating device connected to the water pipe. The high-temperature airflow is sent into the dehumidification box to evaporate the residual moisture on the surface of the moisture collection plate. The moisture is then carried out of the box by the airflow, completing the cleaning of residual moisture inside the storage box for the next cycle.

[0017] Compared with existing technologies, the advantages of this invention are: 1. This invention features a storage box, a sealed cover, a hollow cavity, a blower assembly, and an arc-shaped air duct to form a complete internal air circulation path. This breaks away from the structural drawbacks of traditional rock sugar storage boxes that are completely sealed and airtight. By relying on the negative pressure generated by the blower fan, outside air enters the water storage chamber through the air inlet pipe. After being washed with water and filtered and purified by a filter frame and filter cotton, the air is then introduced into the box for circulation through the arc-shaped air duct. This allows freshly prepared rock sugar with moisture to be directly placed into the box for storage and simultaneously ventilated and dried. There is no need to add an additional independent offline drying process, which simplifies the production process and greatly improves the efficiency of rock sugar transfer and the turnover capacity of the entire production line.

[0018] 2. This storage box for rock sugar preparation is equipped with a dehumidification box, an inclined metal moisture collection plate, and a surrounding water pipe inside the air outlet assembly. This enables active condensation and dehumidification of the air entering the storage box. When the air flows through the dehumidification box, it comes into full contact with the low-temperature moisture collection plate, and the water vapor quickly condenses and adheres to the box, thus removing water. In high-temperature environments, the water pipe can be connected to an external refrigeration device to further cool down and enhance the dehumidification effect. This effectively prevents the water vapor released by the rock sugar itself from accumulating in a sealed environment and condensing into water droplets on the inner wall of the storage box. This eliminates the problem of the rock sugar on the inner wall becoming damp, softening, melting, and sticking to the box body from the root, reducing finished product loss and the amount of manual work required for box cleaning and defective sorting.

[0019] 3. The storage box for preparing rock sugar has a rubber plate on the inside of the air outlet box that elastically abuts against the dehumidification box. Together with multiple moisture collection plates, it forms an airflow obstruction structure. The airflow resistance causes the dehumidification box to vibrate slightly, and the rubber plate provides elastic reset cushioning at the same time. This not only avoids damage from rigid collisions of components, but also allows water droplets condensed on the surface of the moisture collection plates to automatically slide down and be collected along the inclined plate surface, preventing water droplets from dripping directly and wetting the rock sugar. At the same time, the vibration can disrupt the airflow distribution inside the box, which, together with the air duct structure, improves the uniformity of air diffusion, allowing the rock sugar inside the storage box to be evenly dehumidified by the airflow, avoiding localized dampness and clumping.

[0020] 4. This storage box for rock sugar preparation features a streamlined, converging deflector within its air guide mechanism. The bottom of the air outlet box has a matrix arrangement of outlet pipes with intermittently spaced one-way pipes. As airflow passes through, the deflector swings back and forth, creating airflow disturbance. Simultaneously, the converging structure effectively reduces the diameter and speed, enhancing air penetration and allowing for deep ventilation and drying within the gaps of the rock sugar stack. The one-way pipes are equipped with one-way valves, allowing only the drying airflow to enter the storage box in one direction, preventing the backflow of humid air inside the box, ensuring directional airflow circulation, and significantly improving deep dehumidification. This makes it suitable for long-term storage and long-distance transportation of large quantities of highly stacked rock sugar.

[0021] 5. The storage tank for rock sugar preparation has a water tank reserved with two-thirds of the standard water filling volume. A sealing strip is installed at the joint between the sealing cap and the storage tank. At the same time, the water pipe can be connected to external heating equipment, and the blower fan can be started and stopped. It has dual functions of normal storage dehumidification and high-temperature drying of empty boxes. After the rock sugar is taken out, the heating medium through the water pipe raises the temperature of the air flowing through the dehumidification box, evaporates the residual moisture on the moisture collection plate, and carries it out of the box with the airflow. It quickly completes the removal of residues, dehumidification and sterilization of the empty box, inhibits the growth of mold, and extends the service life of the storage tank. The equipment can be recycled and reused, and the temperature and humidity are adjustable. It is suitable for the rock sugar storage needs of different seasons and working conditions, and has strong versatility and practicality. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: Refer to Figures 1-7 A storage box for preparing rock sugar includes a storage box 1 and a sealing cover 2 hinged to the upper opening of the storage box 1. Storage box 1 serves as the overall supporting base and adopts an open structure at the top to hold freshly prepared rock sugar. The sealing lid 2 is hinged to the top of storage box 1 via a hinge, which can be opened and closed freely. The two together form a closed storage cavity. Compared to traditional fixed top covers or completely open storage structures, this structure uses a hinged sealing cover 2, which allows for quick opening and filling of materials and sealing of the cover without the need for additional disassembly and assembly of the cover, making it easy to operate. At the same time, it can be linked with the subsequent ventilation and dehumidification structure. After the cover is closed, the internal air duct system can be opened to provide a closed operating environment for air circulation and air filtration and dehumidification.

[0026] The bottom of the storage box 1 is fixedly installed with several feet 3, and the sealing cover 2 is provided with multiple slots 4 that cooperate with the corresponding feet 3. The sealing cover 2 is provided with an observation window 8. The interior of the sealing cover 2 is a hollow cavity structure. The sealing cover 2 is provided with an air inlet 9, which connects the cavity to the outside. The feet 3 are fixed at the bottom corners of the storage box 1, which serves to support and prevent slipping and isolate the ground moisture. At the same time, the feet 3 can be precisely engaged and matched with the slots 4 of the upper storage box 1 to realize the stacking of multiple sets of storage boxes 1, saving warehouse space. The observation window 8 is embedded in the sealing cover 2, which allows for real-time observation of the storage status, moisture condition and integrity of the rock sugar inside the storage box 1 without opening the sealing cover 2. The sealing cover 2 is set with a hollow cavity and an air inlet 9, which allows outside air to enter the cavity smoothly through the air inlet 9, providing an airflow channel for the subsequent blower assembly 12 to guide the airflow and the air duct to guide the airflow.

[0027] The storage box 1 is equipped with a water storage tank 11 and a blower assembly 12. The water storage tank 11 is connected to the outside through the air inlet pipe 6. The blower assembly 12 includes a filter frame 14, filter cotton 15 and a blower fan 16. The filter frame 14 has the filter cotton 15 inside and fits the air inlet end of the blower fan 16. An arc-shaped air duct 10 is fixed in the cavity of the sealing cover 2. The lower end of the arc-shaped air duct 10 is connected to the air outlet assembly 7. The water storage tank 11 is connected to the outside air through the air inlet pipe 6. When the blower fan 16 in the blower assembly 12 works, it generates negative pressure, which can actively draw outside air into the water storage tank 11. The clean water in the tank is used to wash and purify the air, removing dust and large particulate impurities from the air. The filter frame 14 is equipped with filter cotton 15 that fits into the air inlet of the blower fan 16. It can perform secondary filtration and impurity removal on the washed air and adsorb some water vapor. The purified air enters the cavity of the sealing cover 2 and is then directed downward through the arc-shaped air duct 10 to the interior of the air outlet assembly 7, forming a complete airflow transport link of "external air intake - water washing and purification - secondary filtration - air duct guidance". Existing technologies mostly involve direct air intake without filtration and purification, which easily brings impurities and moisture into the box, causing rock sugar contamination and dampness. This structure uses a water storage tank 11 for washing and a filter cotton 15 for double-layer filtration, combined with an arc-shaped air duct 10 for directional airflow, resulting in cleaner airflow and smoother airflow, reducing the impact of external impurities and moisture on rock sugar storage from the source.

[0028] The feet 3 are evenly fixed at the four corners of the lower surface of the storage box 1. The feet 3 are made of non-slip and wear-resistant hard rubber. The storage box 1 is a square box structure with an open top. The size of the sealing cover 2 matches the open top of the storage box 1. One side of the sealing cover 2 is hinged to the upper side of the storage box 1. When the sealing cover 2 is closed, it completely covers the open top of the storage box 1 and forms a limiting seal. The slot 4 is opened in the middle of the outer wall of the storage box 1. The slot 4 cooperates with the external fixing buckle to lock and fix the sealing cover 2 after it is closed. The observation window 8 is made of transparent tempered glass and is embedded in the reserved window on the side wall of the sealing cover 2. The connection between the observation window 8 and the sealing cover 2 is sealed and waterproofed. The storage status of rock sugar inside the storage box 1 can be observed in real time. The water inlet 5 is vertically opened on the top wall of the sealing cover 2 and is connected to the internal water storage tank 11. The water inlet 5 is equipped with a sealing plug. It is sealed to prevent external dust and moisture from entering the water storage tank 11. The four corners of the base 3 are evenly distributed and made of rubber, which can not only stably support the storage box 1 and prevent slippage and shaking, but also isolate the ground moisture from seeping upwards. The sealing cover 2 matches the opening size of the storage box 1. After the hinge is rotated and closed, it can completely cover the port to form a sealed protection. The slot 4, together with the external buckle, can lock the sealing cover 2 to limit the position and prevent loosening, air leakage and moisture ingress during transportation. The tempered glass observation window 8 is sealed and embedded, which is waterproof and dustproof without obstructing the view, allowing you to observe the rock sugar inside the box at any time as it clumps, melts and dries. Water inlet 5 connects to water storage tank 11 and is equipped with a sealing plug, which allows for convenient addition of clean water to water storage tank 11. After addition, the sealing port keeps the tank sealed and does not affect the negative pressure air intake effect.

[0029] The water storage tank 11 is fixedly embedded in the cavity inside the sealing cover 2. The water storage tank 11 is a closed cavity structure. The top of the water storage tank 11 is connected to the water inlet 5. The side wall of the water storage tank 11 is connected to one end of the air inlet pipe 6. The other end of the air inlet pipe 6 extends to the outside of the sealing cover 2 and communicates with the outside air. The connection between the air inlet pipe 6 and the water storage tank 11 is sealed and bonded. The blower assembly 12 is fixed in the cavity of the sealing cover 2 next to the water storage tank 11. The filter frame 14 is a frame-type hollow structure and is fixed to the air inlet end of the blower fan 16. The filter cotton 15 is detachably snapped into the hollow area inside the filter frame 14. The blower fan 16 is fixedly installed on the inner wall of the cavity of the sealing cover 2 with the air inlet end facing the air outlet side of the water storage tank 11. The air outlet end of the blower fan 16 is connected to the inner cavity of the sealing cover 2, which can draw the air filtered by the water in the water storage tank 11 into the cavity of the sealing cover 2 for circulation. The water storage tank 11 is sealed and embedded in the cavity of the sealing cover 2. Water is added through the water inlet 5 and air is introduced through the air inlet pipe 6. The interface is sealed and bonded to ensure that the negative pressure environment is airtight. After the blower fan 16 is started, it draws the air inside the water storage tank 11 to form a negative pressure, forcing the outside air to continuously enter the water storage tank 11 through the air inlet pipe 6 and pass through the water body to complete the water washing, dust removal and impurity removal. The filter frame 14 has a frame-type hollow structure to facilitate airflow. The filter cotton 15 is detachable and easy to replace and maintain later. It fits the air inlet of the blower fan 16 to finely filter the airflow. The purified air is sent into the cavity of the sealing cover 2 by the blower fan 16, providing a stable and clean air source for subsequent air duct transportation and drying inside the box.

[0030] Example 2: This example differs from Example 1 in that: (Refer to...) Figures 8-18 The air outlet assembly 7 includes an air outlet box 17, an air guide mechanism 18, and a dehumidification box 19. Several metal moisture collection plates 25 are arranged in an array inside the dehumidification box 19. Air outlet holes 22 are evenly opened at the lower end of the dehumidification box 19. Two sets of baffles 20 are rotatably installed inside the air outlet box 17 and equipped with spring coils. A rubber plate 21 is fixed to the inner wall of the air outlet box 17. Several air outlet pipes 26 and one-way pipes 23 are connected to the bottom of the air outlet box 17. A gathering type paddle 24 is movably installed inside the air guide mechanism 18. A water guide pipe 13 passes through the sealing cover 2 and is arranged around the cavity and the outside of the dehumidification box 19. The air outlet assembly 7 has an air outlet box 17 as its main frame, and integrates a dehumidification box 19 and an air guide mechanism 18 inside. The airflow in the cavity of the sealing cover 2 is introduced through the arc-shaped air duct 10 and first enters the dehumidification box 19, which is in full contact with the metal moisture collection plate 25 arranged in an inclined array inside. The metal's thermal conductivity and low temperature characteristics cause water vapor in the air to condense and precipitate, thus achieving active dehumidification. After dehumidification, the air flows into the air outlet box 17 through the air outlet 22, and is then agitated and accelerated by the deflector 24 inside the air guide mechanism 18 before being sent into the storage box 1 through the bottom air outlet pipe 26 and the one-way pipe 23. The baffle 20, in conjunction with the spring coil, enables automatic opening and closing of the air duct. The rubber plate 21 provides elastic support for the vibration of the dehumidification box 19. The water pipe 13 is arranged around the duct and can be connected to external refrigeration or heating equipment to regulate the airflow temperature.

[0031] Multiple sets of arc-shaped air ducts 10 are fixedly installed at the bottom of the cavity inside the sealing cover 2. The upper end of the arc-shaped air duct 10 is connected to the inside of the cavity of the sealing cover 2. The lower end of the arc-shaped air duct 10 extends vertically downward and faces the upper opening of the air outlet box 17. When the sealing cover 2 is fully closed, the lower end of the arc-shaped air duct 10 presses against the baffle 20, causing it to rotate around the pivot and open. The baffles 20 are symmetrically installed in pairs on both sides of the upper opening of the air outlet box 17. A spring coil is fitted between the baffle 20 and the pivot of the air outlet box 17. Under normal conditions, the spring coil drives the two baffles 20 to close in opposite directions and block the upper opening of the air outlet box 17. After the arc-shaped air duct 10 is separated from the baffle 20, the spring coil automatically resets to achieve the blockage, preventing the moisture inside the storage box 1 from flowing back into the cavity of the sealing cover 2 and the air duct. The arc-shaped air duct 10 is fixed at the bottom of the cavity of the sealing cover 2. The upper end connects to the cavity to collect airflow, and the lower end faces the port of the air outlet box 17 to achieve directional airflow. When the sealing cover 2 is fully closed, the baffle 20 at the end of the air duct is pressed down to overcome the spring coil force and make the baffle 20 rotate and open, thus opening the airflow passage. When the sealing cover 2 is opened, the arc-shaped air duct 10 separates from the baffle 20. The spring coil automatically rebounds and drives the two baffles 20 to close and block the port of the air outlet box 17, forming a one-way conduction structure that only allows airflow to be sent downward into the storage box 1, preventing the humid air and odors inside the box from flowing back into the air duct and cavity.

[0032] The dehumidifier box 19 is fixedly installed inside the air outlet box 17 at the upper middle position. The dehumidifier box 19 has a rectangular hollow box structure and is fixedly connected to the inner wall of the air outlet box 17 on all four sides. Several moisture collection plates 25 are arranged at equal intervals from top to bottom inside the dehumidifier box 19. The two ends of the moisture collection plates 25 are fixed to the left and right inner walls of the dehumidifier box 19 and are set downwards. The moisture collection plates 25 are integrally formed with a metal heat-conducting material. Several through-type air outlet holes 22 are evenly opened on the bottom wall of the dehumidifier box 19. The air outlet holes 22 connect the internal cavity of the dehumidifier box 19 with the inner cavity of the lower air outlet box 17. The water guide pipe 13 is fixedly attached to the outer wall of the dehumidifier box 19 and the inner wall of the cavity of the sealing cover 2 in a meandering coil. The two ends of the water guide pipe 13 extend to the outside of the sealing cover 2 and can be connected to external cooling or heating equipment to realize the cooling or heating control of the circulating air. The dehumidification box 19 is fixed in the center of the air outlet box 17. The hollow box provides a sealed buffer space for water vapor condensation. The multi-layered inclined metal moisture collection plate 25 inside increases the contact area with the airflow. The thermal conductivity of the metal can quickly absorb water vapor in the air and condense it into water droplets. The inclined angle makes it easy for the water droplets to slide down and collect naturally, avoiding dripping onto the surface of the rock sugar below. The densely packed air outlets 22 at the bottom allow the dehumidified air to diffuse downwards evenly, ensuring uniform airflow. The meandering coiled water pipes 13 fit into the dehumidification box 19 and the outer wall of the cavity. External cooling can reduce the temperature of the board and enhance condensation dehumidification, while external heating can raise the temperature to evaporate residual moisture on the board, achieving empty box drying and dehumidification.

[0033] The rubber plate 21 is fixedly bonded to the inner side wall of the air outlet box 17 corresponding to the installation position of the dehumidification box 19. The rubber plate 21 is made of elastic soft rubber and elastically abuts against the side wall of the dehumidification box 19. When the dehumidification box 19 vibrates due to air resistance, it relies on the rubber plate 21 to provide elastic reset support, while buffering the vibration amplitude to avoid rigid collision damage to the components. The surface of the moisture collection plate 25 is smooth and the tilt angle is set to 15°~30°, which makes it easy for the water droplets condensed in the air to slide naturally down the plate surface for collection, preventing the condensed water droplets from dripping directly onto the surface of the rock candy below and causing it to become damp and melt. The dehumidification box 19 and the air outlet box 17 are fixed with a gap fit, leaving a small vibration space to ensure the air turbulence effect. The rubber plate 21 fits elastically against the side wall of the dehumidification box 19. When the airflow passes through the dehumidification box 19 and is blocked by the multi-layer moisture collection plate 25, it will cause the dehumidification box 19 to shake and vibrate slightly. The rubber plate 21 uses its own elasticity to buffer, dampen and reset, avoiding the rigid collision between the dehumidification box 19 and the air outlet box 17, which will cause abnormal noise and structural damage. The moisture collection plate 25 is set at a reasonable tilt angle of 15° to 30° and has a smooth surface. The condensed water droplets can slide smoothly down the plate surface and be collected without dripping directly and wetting the rock sugar. At the same time, the reserved gap provides vibration space for the dehumidification box 19. Vibration can disrupt the internal airflow, making the air distribution more disordered and uniform, and improving the overall dehumidification coverage.

[0034] The air guide mechanism 18 is fixedly installed inside the lower side of the air outlet box 17. Multiple sets of levers 24 are vertically arrayed and movably installed inside the air guide mechanism 18. The levers 24 adopt a streamlined structure that is narrow in the middle and wide at both ends. The two ends of the levers 24 are movably hinged to the inner wall of the air guide mechanism 18 through thin shafts. They can swing and vibrate freely in small amplitudes under the airflow. The levers 24 form a narrow-diameter air duct structure between each pair, which can gather the airflow, increase the air velocity, and improve the air delivery penetration. Multiple vertically arranged air outlet pipes 26 are evenly fixed and connected to the bottom wall of the air outlet box 17. The air outlet pipes 26 are arranged in a matrix and their lower ends extend into the internal cavity of the storage box 1. The air guide mechanism 18 has multiple sets of movable hinged converging paddles 24 built in. When the airflow passes through downward, it will push the paddles 24 to swing back and forth, generating airflow disturbance and turbulence. At the same time, the streamlined structure with a narrow middle and wide ends forms a narrow-diameter air channel, which gathers the airflow and speeds up the wind, enhances the air penetration ability, and can penetrate deep into the gaps of the rock candy pile for ventilation and drying, avoiding the occurrence of internal dead corners and dampness. The matrix-arranged air outlet ducts 26 extend vertically into the storage box 1, which can evenly distribute the high-speed disturbed dry airflow to various areas inside the box, achieving ventilation and dehumidification without dead corners. Existing technologies mostly use direct blowing, with low flow rate and weak penetration, which can only dry the surface of the rock sugar, while the inside is prone to moisture and clumping. This structure greatly improves the airflow penetration and coverage by using the baffle 24 to turbulently increase the speed and uniformly distribute the airflow through the matrix air outlet ducts 26, which is suitable for the deep drying and storage needs of large-volume, high-density rock sugar.

[0035] One-way pipes 23 are interspersed between air outlet pipes 26 and fixed to the bottom wall of air outlet box 17. One-way pipes 23 are equipped with one-way valve cores, which only allow the dry airflow to be sprayed out from air outlet box 17 into storage box 1 in one direction, preventing the humid air inside storage box 1 from flowing back. The lower end faces of air outlet pipes 26 and one-way pipes 23 are flush and both extend to the upper space of the inner cavity of storage box 1. The connection between air outlet pipes 26, one-way pipes 23 and the bottom wall of air outlet box 17 is sealed by welding to ensure no gaps or air leakage, so that the airflow is directed into the storage box 1 to carry out all-round ventilation and drying treatment of rock sugar. One-way pipe 23 and air outlet pipe 26 are arranged at intervals and air is discharged synchronously. The internal one-way valve core limits the airflow to be sent into the storage box 1 from top to bottom, strictly blocking the upward flow of humid air and water vapor in the box to the air outlet box 17 and the air duct, preventing moisture from circulating and accumulating. The lower ends of the air outlet pipe 26 and the one-way pipe 23 extend into the upper part of the box, which can evenly blow the rock sugar pile from top to bottom. The connection is sealed and welded without any air leakage gaps, ensuring that the dry airflow after dehumidification and purification is directed into the box without any air volume loss or impurities entering.

[0036] The filter frame 14 is detachably clipped onto the outer frame of the air inlet end of the blower fan 16. The filter cotton 15 is laid flat and embedded inside the filter frame 14 and completely covers the ventilation area. It can perform secondary dust filtration and remove some moisture from the air entering the blower fan 16. The rated water filling height inside the water storage tank 11 is two-thirds of the cavity volume, leaving enough airflow buffer space. The blower fan 16 and the water guide pipe 13 are connected to external control switches and temperature control equipment, which can start and stop the blower and switch the cooling and heating modes according to the ambient temperature and humidity. The sealing cover 2 and the storage box 1 are provided with an annular sealing strip to further improve the overall sealing performance after closing and prevent external moisture from entering the box. The filter frame 14 has a detachable snap-on structure that makes it easy to remove and replace the filter cotton 15 at any time, and the maintenance is simple and convenient. The filter cotton 15 fully covers the ventilation area, which can further intercept dust and absorb some moisture in the air after it has been washed, thus improving the cleanliness and dryness of the intake air. The water storage tank 11 is limited to two-thirds of the water filling height, which ensures the washing effect and reserves the upper space as an airflow buffer channel to prevent water from overflowing and backflowing into the air duct; the blower fan 16 and the water guide pipe 13 are connected to external control equipment, which can flexibly start and stop the blower and switch between cooling dehumidification or heating drying modes according to the ambient temperature and humidity to adapt to different seasonal climates. An annular sealing strip is added to the joint of the sealing cap 2 to further seal the splicing gap and prevent external moisture and dust from entering through the gap.

[0037] The specific operating steps of this device are as follows: First, place the prepared rock sugar in storage box 1 and fill it completely. After filling, reduce the gap between the rock sugar particles by appropriate vibration to avoid the rock sugar breaking due to transportation vibration. Next, cover the sealing cap 2 and start the blower fan 16. After the blower fan 16 starts, it will draw out the air in the water storage tank 11. The air will be initially filtered by the filter cotton 15, creating a negative pressure in the water storage tank 11. At this time, under the action of the pressure difference between the inside and outside, the outside air will be drawn into the water storage tank 11 through the air inlet pipe 6 (the water in the water storage tank 11 is injected through the water inlet 5 and the water volume is kept at two-thirds of the water storage tank 11). The drawn-in air will be filtered by the water in the water storage tank 11 to remove particulate impurities contained in the air. The air drawn in by the blower fan 16 enters the interior of the sealing cover 2 through the air inlet 9 on the sealing cover 2 (the sealing cover 2 is hollow and has a cavity inside, and the air entering from the air inlet 9 will fill the cavity), and then enters the dehumidification box 19 through the arc-shaped air duct 10 connected to the cavity (after the sealing cover 2 is closed, the arc-shaped air duct 10 will press against the baffle 20 to open the baffle 20. The baffle 20 and the air outlet box 17 are rotatably connected and are equipped with a spring coil. When the arc-shaped air duct 10 is separated from the baffle 20, the two baffles 20 will block the air outlet box 17 under the action of the spring coil). After the air enters the dehumidification box 19, it comes into contact with the numerous moisture collection plates 25 inside the dehumidification box 19. Since the moisture collection plates 25 are made of metal and have a low temperature, the moisture in the air will condense on the moisture collection plates 25 and adhere to them, thus removing the moisture in the air. If the outside air temperature is high, the water pipe 13 will be cooled by the refrigeration equipment, so that the air entering the sealed cover 2 is in a low temperature state. The air dehumidified by the moisture collection plate 25 will enter the air outlet box 17 through multiple air outlet holes 22 on the dehumidification box 19, and then be sprayed into the storage box 1 through numerous air outlet pipes 26 and one-way pipes 23 on the air outlet box 17 to ventilate and dry the rock sugar inside the storage box 1. Because the dehumidifier box 19 has multiple moisture collection plates 25 inside, the air resistance is high. This causes the dehumidifier box 19 to vibrate, making the air turbulent (the rubber plate 21 provides vibration reset elasticity, and the vibration will cause the water droplets attached to the moisture collection plate 25 to fall off. Here, the moisture collection plate 25 is designed to be inclined, which can effectively collect water and prevent water droplets from falling off). At the same time, the air is blocked by the deflector 24 after passing through the air outlet duct 26. The warm air will drive the deflector 24 to vibrate. At the same time, the deflector 24 adopts a converging design, which has the function of increasing the air flow rate. By making the air vibrate and increasing the air flow rate, the air is provided with stronger penetrating power. Empty box dehumidification: Remove the rock sugar from the storage box 1, heat the water in the water pipe 13 through an external device, so that the air entering the cavity of the sealed cover 2 is at a high temperature. After the high temperature air enters the dehumidification box 19, the water on the moisture collection plate 25 will evaporate, thereby achieving the purpose of removing residual water in the empty box.

10. A method for storing rock sugar, used in a storage box for rock sugar preparation as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. Loading and placing: The industrially prepared rock sugar is neatly filled into the storage box (1). After filling, the storage box (1) is slightly vibrated to reduce the gap between the rock sugar particles and avoid the rock sugar from breaking during transportation. After filling, the sealing cover (2) is rotated to cover the upper end of the storage box (1). The sealing cover (2) is locked and fixed by the slot (4) and the external buckle. S2, Water Pretreatment: Inject clean water into the water storage tank (11) through the water inlet (5) at the top of the sealing cover (2), and control the water volume to be two-thirds of the volume of the water storage tank (11). After the water is added, seal the water inlet (5) port. S3, blower air intake filtration: Start the blower fan (16). The blower fan (16) works to draw out the air inside the water storage tank (11) to form a negative pressure. The outside air is drawn into the water storage tank (11) through the air inlet pipe (6). The air is washed with clean water in the water storage tank (11) to remove particulate impurities. After being filtered a second time by the filter cotton (15) in the filter frame (14), it is sent into the hollow cavity of the sealing cover (2). S4. Air duct opening and closing: When the sealing cover (2) is closed, the lower end of the arc-shaped air duct (10) presses against the baffle (20) on the air outlet box (17) to overcome the spring force and rotate open. The air in the cavity of the sealing cover (2) is smoothly introduced into the dehumidification box (19) through the arc-shaped air duct (10). S5, Low-temperature condensation dehumidification: After the air enters the dehumidification box (19), it comes into full contact with the moisture collection plate (25) arranged in an array. The low-temperature characteristics of the metal moisture collection plate (25) cause water vapor in the air to condense and adhere. In the case of high external temperature environment, the air is cooled by the external cooling equipment connected through the water pipe (13), which further reduces the air inlet temperature and improves the dehumidification effect. The dehumidification box (19) is subjected to airflow resistance and elastic support of the rubber plate (21) to generate micro-vibration, causing the condensed water droplets to slide down and be collected along the inclined moisture collection plate (25). S6, Turbulent air supply drying: After dehumidification, the air enters the air outlet box (17) through the air outlet (22) of the dehumidification box (19), and after being agitated and accelerated by the inner tumbler (24) of the air guide mechanism (18), it is sprayed into the storage box (1) in one direction through the air outlet pipe (26) and the one-way pipe (23). The vibrating airflow and high-speed penetrating airflow are used to continuously ventilate and dehumidify the rock sugar, so as to achieve drying while storing. S7. Empty box dehumidification: After the rock sugar in the storage box (1) is removed, the medium inside the pipe is heated by the external heating device connected to the water pipe (13). The high-temperature airflow is sent into the dehumidification box (19) to evaporate the residual moisture on the surface of the moisture collection plate (25) and carry it out of the box with the airflow, thus completing the cleaning of residual moisture inside the storage box (1) for the next cycle of use.
