Description

Technical Field

[0001] This utility model relates to the field of fresh flower preservation technology, and in particular to a commercial processing box for fresh-cut flowers at their place of origin. Background Technology

[0002] Post-harvest processing of cut flowers is a crucial step in determining their commercial value, especially for typical climacteric flowers like roses, which experience rapid post-harvest aging and are difficult to store. During storage and transportation, roses are prone to problems such as premature ethylene-induced respiration peaks, leading to browning of petal edges, rotting of the stem base, and mold growth, severely shortening their shelf life and resulting in post-harvest losses as high as 30%.

[0003] The current core problem lies in the insufficient application of key technologies such as postharvest precooling and physiological and pathological regulation.

[0004] Low efficiency of pre-cooling treatment: Most processing boxes use simple insulation materials and lack a systematic low temperature maintenance structure, making it difficult to quickly and stably control the temperature of fresh cut flowers at the ideal pre-cooling temperature of about 4°C at the production site. This results in the ineffective inhibition of respiratory metabolism, accelerated ethylene synthesis, and accelerated petal senescence.

[0005] Lack of synergistic atomization treatment technology: Existing atomization equipment mostly uses single agent treatment, lacking the synergistic effect of gases (such as high carbon dioxide gas) and preservatives (such as 1-MCP, bactericides). The droplet particles are unevenly distributed in the chamber, which cannot achieve efficient blocking of ethylene receptors and comprehensive killing of microorganisms. The reduction rate of petal mold infection is less than 50%.

[0006] Lack of long-lasting slow-release preservation capability: For the ethylene continuously released by fresh cut flowers and the microorganisms that grow in the environment, the existing equipment relies on single fumigation with chemicals and lacks a slow-release treatment device that continuously releases antibacterial components. As a result, the browning rate of petals rises by more than 30% within 24 hours after treatment, requiring frequent replenishment of chemicals, which increases labor costs and the risk of chemical residues.

[0007] To address the aforementioned issues, there is an urgent need to provide a commercial processing box for cut flowers at their production sites, which would primarily solve the industry problems of low commercial processing levels and high post-harvest losses in my country's cut flower production areas. Utility Model Content

[0008] This invention addresses the shortcomings of existing technologies by developing a commercial processing box for fresh-cut flowers at their production sites. Through the coordinated operation of an insulated and airtight box with refrigeration equipment, atomization equipment, internal circulation fan, slow-release preservative, and gas detector, this invention achieves low-temperature storage of fresh-cut flowers after harvest, uniform atomization of the agent, continuous adsorption of ethylene, and control of the gas environment. This effectively extends the preservation period, improves the preservation quality, and reduces processing costs.

[0009] The technical solution to the technical problem solved by this utility model is as follows:

[0010] This application provides a commercial processing box for fresh-cut flowers at the production site, including an insulated box body and a door. The insulated box door is sealed to the box body, and a refrigeration device is installed on the outer wall of the insulated box body. An atomizing device is connected to the outside of the insulated box body, and the atomizing device is connected to the inside of the insulated box body through an atomizing output pipe. A carbon dioxide cylinder is connected to the atomizing output pipe. The atomizing device stores a preservative for fresh-cut flowers. An internal circulation fan is installed inside the insulated box body. A partition is provided at the bottom of the insulated box body, and through holes are evenly opened on the partition. The partition and the bottom surface of the insulated box body form a partition layer, and an open-type storage box for containing a slow-release preservative is placed inside the partition layer.

[0011] As an improvement to the above solution, a gas detector is installed on the outside of the insulation box and communicates with the inside of the insulation box to detect the concentration of oxygen and carbon dioxide in the box in real time.

[0012] As an improvement to the above solution, the material of the insulated box is polyurethane, and the joints of the insulated box are sealed with sealant or sealing strips.

[0013] As an improvement to the above solution, the door is movable, and the movable door is connected to the insulated box body via a slide rail.

[0014] As an improvement to the above solution, the refrigeration equipment is a wall-mounted structure, which is fixed to the outer wall of the insulated box by bolts or clips.

[0015] As an improvement to the above scheme, the treatment agent includes 1-MCP and a bactericide.

[0016] As an improvement to the above solution, the slow-release preservative includes solid potassium permanganate material and slow-release essential oil preservative material.

[0017] As an improvement to the above solution, the carbon dioxide cylinder is connected to the atomization output pipe of the atomization device through a gas pipeline equipped with a pressure reducing valve.

[0018] As an improvement to the above solution, the opening of the storage box faces the partition.

[0019] Compared with existing technologies, the above solution has the following advantages or beneficial effects:

[0020] This application provides a commercial processing box for cut flowers at their production sites. The insulated and airtight box and refrigeration equipment create a stable low-temperature environment, inhibiting the respiration and microbial growth of cut flowers and extending the shelf life. The atomizing equipment, carbon dioxide cylinder, and internal circulation fan work together to achieve uniform diffusion of the treatment agent, improving the ethylene inhibition and sterilization effects. The partitions, storage boxes, and slow-release preservatives form a continuous protection system, dynamically adsorbing ethylene and slowly releasing antibacterial agents. The gas detector and pressure reducing valve are used to precisely regulate the gas environment to adapt to the needs of different processing stages. This application improves the applicability and ease of operation of the equipment, and the integration of multiple technologies achieves quality improvement and environmental safety, forming a complete preservation chain.

[0026] Example 1

[0027] See Figure 1 and 2 This embodiment provides a commercial processing box for fresh-cut flowers at their production site, including an insulated box body 9 and a box door 2. The insulated box body 9 is made of polyurethane material, which has excellent thermal insulation properties, effectively reducing heat exchange between the insulated box body 9 and the outside environment, and maintaining a stable temperature inside the insulated box body 9. The insulated box body 9 is airtight. By treating the joints of the insulated box body 9 with sealing materials such as sealant and sealing strips, the overall airtightness of the insulated box body 9 is ensured, preventing air leakage and creating a stable sealed environment inside the insulated box body 9. This is crucial for maintaining the stability of parameters such as gas concentration and temperature inside the insulated box body 9.

[0028] Door 2 is an insulated airtight door, made of the same or similar material as the insulated box body 9, and also has good insulation and airtight performance. Door 2 can be set to be movable. The insulated box body 9 is equipped with a slide rail, and door 2 is connected to the slide rail through pulleys and other components, and can be moved along the slide rail to open or close.

[0029] A wall-mounted refrigeration unit 1 is installed on the outer wall of the insulated box 9. The refrigeration unit 1 is fixed to the outer wall of the insulated box 9 by bolts, clips, and other fasteners, for example, it can be installed on the top or side of the insulated box 9. The refrigeration unit 1 is connected to the interior of the insulated box 9 and can cool the insulated box 9, lowering the temperature inside the insulated box 9, providing a low-temperature storage environment for cut flowers. The low temperature can inhibit the respiration of cut flowers and the growth of microorganisms, thus extending their shelf life.

[0030] An atomizing device 7 is connected to the outside of the insulated box 9, and the atomizing device 7 is connected to the insulated box 9 via an atomizing output pipe 6. One end of the atomizing output pipe 6 is connected to the atomizing outlet of the atomizing device 7, and the other end extends into the insulated box 9 through the wall of the insulated box 9. The connection between the atomizing output pipe 6 and the wall of the insulated box 9 is sealed to prevent gas leakage. A carbon dioxide cylinder 8 is connected to the atomizing device 7 via a gas pipeline. A pressure reducing valve 11 is installed on the gas pipeline to regulate the output pressure and flow rate of carbon dioxide. The atomizing device 7 stores a treatment agent, including 1-MCP and a fungicide. 1-MCP is an ethylene inhibitor that can inhibit the aging process of cut flowers; the fungicide can kill microorganisms inside the insulated box 9 and reduce the occurrence of diseases in cut flowers. When the atomizing device 7 is working, it atomizes 1-MCP and the bactericide. The droplets are carried by carbon dioxide gas and enter the insulation box 9 through the atomizing output pipe 6. Carbon dioxide, as a carrier, enables the droplets to be more evenly distributed in the insulation box 9, thereby improving the atomization effect.

[0031] An internal circulation fan 5 is installed inside the insulation box 9. The internal circulation fan 5 can be installed at the top, side, or bottom of the insulation box 9 and fixed inside the insulation box 9 by brackets or other fasteners. When the internal circulation fan 5 is working, it can drive the air flow inside the insulation box 9, making the air evenly mixed. This ensures that the cut flowers in all positions inside the insulation box 9 are exposed to the same concentration of treatment gas (such as 1-MCP, fungicide, etc.) and have a uniform temperature, avoiding situations where the concentration is too high or too low in some areas or the temperature is uneven, thereby improving the consistency and effectiveness of the cut flower treatment.

[0032] A partition 3 is installed at the bottom of the insulated box 9. The partition 3 is parallel to the bottom surface of the insulated box 9, and its perimeter is connected to the inner wall of the insulated box 9, for example, by welding or bolting, forming a partition between the partition 3 and the bottom surface of the insulated box 9. The partition 3 has evenly spaced through holes, the size and distribution of which ensure smooth airflow between the gas inside the partition and the gas in the upper space inside the insulated box 9. An upward-facing storage box 4 is placed inside the partition, allowing the gas released by the slow-release preservative to enter the space above it through the through holes. The storage box 4 contains a slow-release preservative, which can be a solid potassium permanganate material or a slow-release essential oil preservative. Solid potassium permanganate material can absorb ethylene gas inside the insulation box 9. Ethylene is a gas that promotes the aging of cut flowers, and absorbing ethylene can delay the aging of cut flowers. The slow-release essential oil preservation material has antibacterial and bactericidal effects, which can inhibit the growth and reproduction of microorganisms inside the insulation box 9. The combination of the two plays a role in preservation.

[0033] A gas detector 10 is installed outside the insulated chamber 9. The gas detector 10 is connected to the inside of the insulated chamber 9 via a pipeline, which is also equipped with a switch valve to monitor the oxygen and carbon dioxide concentrations inside the insulated chamber 9 in real time. The gas detector 10 is connected to an external control system (such as a display screen, operation panel, etc.) to display and provide feedback on the detected data in real time. Operators can adjust the operating parameters of relevant equipment based on the detection data to ensure that the gas environment inside the insulated chamber 9 meets the requirements for fresh-cut flower processing.

[0034] Application Examples

[0035] When using the commercially available insulated box 9 from the fresh-cut flower production area, the specific steps are as follows:

[0036] Fresh-cut flowers are placed in the insulated box 9 immediately after harvesting, with a gap of about 10cm when stacking them. The gap design ensures smooth air circulation inside the insulated box 9, allowing the fresh-cut flowers to fully contact the processing gas. It also facilitates heat dissipation and prevents localized temperature rises caused by overly dense stacking, which could affect the quality of the fresh-cut flowers.

[0037] The slow-release preservatives (i.e., solid potassium permanganate and slow-release essential oil preservatives) are filled into storage box 4 and pushed into the bottom compartment. Storage box 4 is placed in the compartment with its opening facing upwards. The through holes on the partition 3 allow the gas released by the slow-release preservatives to enter the insulation box 9, providing continuous preservation for the cut flowers. The solid potassium permanganate slowly releases and absorbs the ethylene produced in the insulation box 9, delaying the aging of the cut flowers; the slow-release essential oil preservatives slowly release antibacterial components, inhibiting microbial growth. The slow-release effect of both can maintain a good preservation environment in the insulation box 9 for a long time, reducing the hassle of frequently changing the preservatives.

[0038] Close the door 2. Since the door 2 is an insulated airtight door, it is tightly connected to the insulated box 9 to ensure the airtightness of the insulated box 9, prevent external gas and heat from entering the insulated box 9, and maintain the stability of the internal environment of the insulated box 9.

[0039] The refrigeration equipment 1 is started and the temperature is set to 4℃. The wall-mounted refrigeration equipment 1 begins to work, cooling the insulated box 9, causing the temperature inside the insulated box 9 to drop rapidly and stabilize at around 4℃. The low-temperature environment can significantly inhibit the respiration of cut flowers, reduce the consumption of nutrients, and also inhibit the growth and reproduction of microorganisms, thus extending the shelf life of cut flowers.

[0040] Start the internal circulation fan 5. The internal circulation fan 5 drives the air flow in the heat preservation box 9, so that the cold air generated by the refrigeration equipment 1 and the atomized gas are evenly distributed in the heat preservation box 9, avoiding temperature stratification and uneven gas concentration, and ensuring that every cut flower is in the same excellent environment.

[0041] The atomizing device 7 is activated to atomize 1-MCP and the fungicide, while the carbon dioxide cylinder 8 is simultaneously activated. The atomizing device 7 atomizes the 1-MCP and fungicide into fine droplets. The carbon dioxide gas released from the carbon dioxide cylinder 8 acts as a carrier, carrying the droplets into the insulation chamber 9. 1-MCP can bind to ethylene receptors on the surface of cut flower cells, inhibiting the effects of ethylene and thus delaying the aging and wilting of the cut flowers. The fungicide can kill or inhibit bacteria, fungi, and other microorganisms within the insulation chamber 9, reducing the occurrence of diseases in the cut flowers. The carbon dioxide gas not only serves as a carrier for the droplets but also creates a high-carbon dioxide environment when the carbon dioxide concentration within the insulation chamber 9 is subsequently adjusted, further inhibiting the respiration of the cut flowers and the growth of microorganisms.

[0042] The gas detector 10 monitors the concentration of oxygen and carbon dioxide gas inside the insulation box 9 in real time. Based on the monitoring data, it adjusts the pressure reducing valve 11 on the gas pipeline of the carbon dioxide cylinder 8 to maintain synchronous operation with the atomizing equipment 7. This ensures that the pressure and flow rate of the gas inside the insulation box 9 are stable during the atomization process, so that the droplet particles can be evenly distributed inside the insulation box 9.

[0043] After the atomized fumigation is completed, the carbon dioxide concentration inside the insulated box 9 reaches 10%-12%. At this point, the carbon dioxide cylinder 8 and the atomization equipment 7 are turned off, and pre-cooling and low-temperature storage are carried out. The high concentration of carbon dioxide can further inhibit the metabolic activity of cut flowers, prolonging their shelf life. Combined with low-temperature storage, it provides the best preservation environment for cut flowers.

[0044] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
