Description

Technical Field

[0001] This utility model relates to the field of kiwifruit preservation technology, and in particular to a controlled atmosphere cold storage for kiwifruit. Background Technology

[0002] Kiwifruit is a deciduous vine fruit tree belonging to the Actinidiaceae family and the Actinidis genus. Its fruit is rich in various nutrients and minerals, making it very popular. Controlled atmosphere storage is used in the preservation of kiwifruit. Controlled atmosphere storage is also known as controlled atmosphere cold storage or controlled atmosphere preservation storage. It is a preservation facility that further regulates and controls the gas composition inside the storage room based on cold storage. It is the most advanced method for preserving and storing fruits and vegetables today.

[0003] For example, patent CN220135804U discloses a controlled atmosphere cold storage for fresh food preservation, including a storage body and a cargo elevator. The storage body is fixedly connected to a partition, and the storage body is movably connected to a locking assembly. The locking assembly includes a second sliding rod, a second sliding sleeve, a plug, a collar, and a spring. The upper end of the storage body is fixedly connected to a humidification assembly, which includes a water tank, a pump body, a water outlet pipe, and an atomizing nozzle.

[0004] During use, the aforementioned controlled atmosphere cold storage for fresh-keeping has a fixed humidification angle and area formed by the humidification components in its humidification unit. As a result, it is impossible to humidify multiple layers of kiwifruit with minimal dead angles. Consequently, the kiwifruit that is covered and humidified is prone to damage, while the kiwifruit that is not humidified may not achieve a good preservation effect. Therefore, this application provides a controlled atmosphere cold storage for kiwifruit to meet the needs. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide a controlled atmosphere cold storage for kiwifruit to address the issue that existing cold storage systems, due to the fixed humidification angle and area formed by the humidification components in their humidification units, cannot achieve minimal dead angle humidification for multi-layered kiwifruit, thus causing kiwifruit that is covered and humidified to be easily damaged, while kiwifruit that is not humidified may not achieve a good preservation effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A modified atmosphere cold storage for kiwifruit includes a storage body with an opening and closing mechanism at the front end and storage racks inside. A uniform humidification mechanism is installed both inside and outside the storage body. Portable mechanisms are installed at the front ends of multiple storage racks. The uniform humidification mechanism includes a water tank installed on one side of the storage body. A water pump is located above the water tank, and connecting pipes are connected to the upper and lower ends of the water pump. A lifting humidification assembly is installed inside the storage body, including two second lead screw sleeves with spray guide frames around their peripheries. Telescopic water pipes are connected above the spray guide frames, and atomizing nozzles are located below the spray guide frames. A uniform humidification component is installed below the multiple storage racks.

[0008] Optionally, the lifting humidification component includes a mounting frame, which is fixed to one side of the interior of the humidifier body. A dual-head motor is installed at the upper center of the mounting frame, and rotating rods are connected to both ends of the dual-head motor. A third bevel gear is fixed to one end of each of the two rotating rods, and a fourth bevel gear meshes with one side of each of the two third bevel gears. A transmission screw is fixed to the middle of each of the two fourth bevel gears, and a second screw sleeve is screwed onto one side of each of the two transmission screws. Slides are installed on both sides of the interior of the humidifier body.

[0009] Optionally, the carriage and the spray guide frame are connected by a movable guide connection.

[0010] Optionally, the spray guide frame is connected to the top of the tank body via a telescopic water pipe, and one end of a connecting pipe on the top of the tank body is connected to the corresponding end of the telescopic water pipe.

[0011] Optionally, the uniform component includes an assembly frame, which is disposed below multiple mounting frames. An exhaust fan is installed in the middle of the assembly frame, and a second drive rod is installed in the middle of the multiple exhaust fans. Two of the four second drive rods have two synchronous pulleys fixed around their periphery, and a synchronous belt is fitted around the periphery of one of the two second drive rods corresponding to the synchronous pulley. The other two second drive rods have a synchronous pulley fixed around their periphery, and the synchronous pulley is also fitted with a synchronous belt. A flow guide frame is connected to the rear end of the multiple assembly frames, and a flow diffuser frame is connected below the flow guide frame.

[0012] Optionally, the flow guide and the flow diffuser are interconnected.

[0013] Optionally, the opening and closing mechanism includes a positive and negative lead screw, which is installed in the middle of the lower front end of the storage body. A first bevel gear is fixed at one end of the positive and negative lead screw, and a second bevel gear meshes with one side of the first bevel gear. A first transmission rod is fixed in the middle of the second bevel gear, and a first motor is installed at one end of the first transmission rod. First lead screw sleeves are screwed on both sides of the middle of the positive and negative lead screw, and a movable storage door is fixed above the two first lead screw sleeves. An upper guide frame is fixed above the front end of the storage body, and a supporting movable wheel is installed below each end of the two movable storage doors.

[0014] Optionally, the movable door and the upper guide frame are connected by a movable guide connection.

[0015] Optionally, the portable mechanism includes a side guide rod, which is fixed to the front end of one of the mounting frames. A guide sleeve is fitted around one side of the side guide rod, and a mounting ladder is fixed below the guide sleeve. A lower mounting frame is connected below the mounting ladder, and a first slot is provided in the middle of the front end of the lower mounting frame. A rod is inserted into the middle of the first slot, and a second slot is provided at the front end of the fixed edge at the lower end of the storage body.

[0016] Optionally, the lower rack connected below the ladder forms a movable guide connection with the fixed edge at the lower end of the warehouse body.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above scheme, by setting up a uniform humidification mechanism, personnel can start a water pump during the storage of kiwifruit. Guided by two connecting pipes and a telescopic water pipe, cold water is evenly sprayed from the atomizing nozzles set on one side of the spray guide frame. In this state, personnel start a double-headed motor to make the rotating rods at both ends rotate the third bevel gear. The fourth bevel gear meshing with the gear will rotate its own fixed transmission screw. At this time, the second screw sleeve acting with the two screws can move the spray guide frame up and down with the guide frame, thereby controlling the spray humidification of the kiwifruit on the multi-layer rack by the atomizing nozzles and reducing dead zones. At the same time, personnel start multiple second motors simultaneously. With the cooperation of multiple sets of second transmission rods, synchronous pulleys and synchronous belts, multiple exhaust fans can be used to guide the airflow. With the airflow guidance of the guide frame and the diffuser frame, the sprayed humid and cold air can be evenly spread on the kiwifruit, thereby achieving the purpose of efficient preservation.

[0019] By setting up an opening and closing mechanism, when staff need to enter the controlled atmosphere cold storage to retrieve or store kiwifruit, the first motor can be started in advance to rotate the first transmission rod and the second bevel gear. The first bevel gear, which interacts with the gear, will rotate the forward and reverse lead screws. At this time, the two first lead screw sleeves, which interact with the lead screws, will move relative to each other with their fixed movable storage doors, in conjunction with the guide frame and the support movable wheel, thereby achieving the purpose of opening the storage door. Moreover, the opening and closing distance can be freely controlled, thereby reducing the loss of cold air inside the storage.

[0020] By incorporating a portable mechanism, when personnel want to retrieve kiwis from different locations on different racks, they can first remove the first slot in the middle of the lower rack and the insert rod in the middle of the corresponding second slot on the fixed side. Then, by utilizing the mobility between the fixed side and the lower rack, and between the guide sleeve and the corresponding side guide rod, the position of the ladder can be adjusted. After adjustment, the insert rod can be aligned and inserted into the middle of the first slot and the middle of the corresponding second slot on the fixed side. It is portable and practical.

Then, the position of the mounting ladder 53 can be adjusted by using the mobility between the fixed edge and the lower mounting rack 54, and between the guide sleeve 52 and the corresponding side mounting guide rod 51. After the adjustment is completed, the insertion rod 56 can be inserted into the first slot 55 and the middle of the second slot 57 corresponding to the fixed edge. It is portable and practical.

[0039] The working principle of the technical solution provided by this utility model is as follows:

Guided by two connecting pipes 43 and a telescopic water pipe 46, cold water can be evenly sprayed from the atomizing nozzles 47 located on one side of the spray guide frame 45. In this state, personnel can activate the dual-head motor 442 to make the rotating rods 443 at both ends rotate the third bevel gear 444. As a result, the fourth bevel gear 445, which meshes with the gear, will rotate its own fixed transmission screw 446. At this time, the second... The lead screw sleeve 447 can guide the spray guide frame 45 to move up and down in coordination with the slide 448, thereby controlling the atomizing nozzles 47 to spray and humidify the kiwifruit on the multi-layer rack 3, reducing dead zones. At the same time, personnel can simultaneously start multiple second motors 484. With the cooperation of multiple sets of second transmission rods 483, synchronous pulleys 485 and synchronous belts 486, multiple exhaust fans 482 can be activated to induce airflow. With the airflow guidance of the guide frame 487 and the diffuser frame 488, the sprayed humid and cool air can be evenly distributed on the surface.
