Description

Technical Field

[0001] The present invention relates to the technical field of fresh cut flower processing, in particular to a sterilization processing method and system for fresh cut flowers. Background Art

[0002] Fresh cut flowers are various flowers, inflorescences or branches that are cut for viewing. Flowers are the main body of isolated plant materials and are used in various occasions that require viewing, such as flower arrangement and flower baskets.

[0003] In common fresh cut flower processing methods, the steps are usually picking, pretreatment, precooling, packaging and transportation. In the pretreatment step, in order to prolong the flowering period and ensure the smooth opening of the flowers, preservatives and fungicides are generally added. For example, patent number CN114651816B "A preservative for fresh cut peony flowers and its application" is used for preservation and sterilization to ensure the normal opening of flowers and prolong the flowering period.

[0004] However, the use of preservatives and fungicides, on the one hand, adds additional chemical substances, which prolongs the flowering period while also leaving residues on the flowers. On the other hand, the processing and production of fresh cut flowers, as well as the handling and discharge of chemical substances, have an impact on the environment. Summary of the Invention

[0005] The object of the present invention is to provide a sterilization method and system for fresh cut flowers, which sterilizes and preserves fresh cut flowers by performing three-stage sterilization treatments of vacuum, ozone and high-voltage pulse electric field after pre-cooling. No additional chemical reagents need to be added during the process. Low-concentration ozone is environmentally friendly and can be discharged directly. The high-voltage pulse electric field improves the low-temperature disinfection effect, thereby solving the problems of residues and pollution caused by the additional addition of preservatives and bactericides.

[0006] In order to overcome the above-mentioned shortcomings, the present invention provides a method for sterilizing fresh cut flowers, comprising the following steps:

[0007] Step 1: Pick the flowers 10-20 cm from the bottom of the flower;

[0008] Step 2: Prune the branches, remove the excess branches and leaves on the stems, and keep a small part of the branches and leaves for beauty;

[0009] Step 3: Pre-cooling: To preserve freshness, transfer the pruned flowers to a processing tank and pre-cool them at a temperature not exceeding 4°C for 8-12 hours.

[0010] Step 4: Vacuum treatment: evacuate the treatment tank and maintain it at low temperature and negative pressure for 1 to 2 hours to perform primary disinfection, vacuum insecticide and aerobic bacteria elimination;

[0011] Step 5: Ozone treatment: ozone is introduced into the treatment tank and maintained in the ozone environment for 30 minutes to 1 hour for secondary disinfection;

[0012] Step 6: High-voltage pulse electric field sterilization: Turn on the high-voltage pulse electric field generating device and use the high-voltage pulse electric field sterilizer to treat for 5 to 10 minutes in an ozone environment for three-level disinfection. The high-voltage pulse electric field destroys the cell membrane and completely kills the bacteria.

[0013] Step seven, ozone emission, using the exhaust system to discharge ozone from the treatment tank;

[0014] Step 8: Take out the fresh cut flowers, package and sell them.

[0015] Preferably, the pre-cooling temperature in step three is 0-4° C., and the pre-cooling time is 8-10 hours.

[0016] Preferably, the vacuum degree in step 4 is 10000~15000Pa, and the oxygen concentration is lower than 0.5%.

[0017] Preferably, the ozone concentration in step 5 is greater than or equal to 60 mg / m 3 , relative humidity is greater than or equal to 70%, and the treatment time starts to be calculated after reaching the treatment concentration, and the treatment time is 30~40min.

[0018] Preferably, the high-voltage pulse electric field in step six has an electric field strength of 17.9-18.2 kV / cm, a pulse width of 1.8-2.2 μs, and 380-420 pulses per second.

[0019] A fresh cut flower sterilization treatment system using the above-mentioned fresh cut flower sterilization treatment method includes a treatment tank, a refrigeration device, a vacuum equipment, an ozone generating device, a high-voltage pulse electric field sterilization device and an exhaust device. The high-voltage pulse electric field sterilization device is embedded in the treatment tank, and the refrigeration device, the vacuum equipment, the ozone generating device and the exhaust device are all arranged outside the treatment tank. The refrigeration end of the refrigeration device, the exhaust end of the vacuum equipment, the air outlet end of the ozone generating device and the exhaust end of the exhaust device are all connected to the reaction chamber of the high-voltage pulse electric field sterilization device through corresponding connecting pipes, and the connecting pipes are all provided with valves corresponding to the pipes.

[0020] Preferably, a sealed door is provided on one side of the processing tank, and an installation space is provided inside the processing tank. The high-voltage pulse electric field sterilization equipment can be detachably placed in the installation space. After opening the door, the fresh cut flowers to be processed are placed in the reaction chamber of the high-voltage pulse electric field sterilization equipment.

[0021] Preferably, the refrigeration equipment and vacuum equipment are located on both sides of the top of the processing tank, and the refrigeration end of the refrigeration equipment and the exhaust end of the vacuum equipment pass through the processing tank and the high-voltage pulse electric field sterilization equipment and are sealed and connected to the top of the reaction chamber.

Ozone plays a role in sterilization and preservation, and after sterilization, it is accelerated to decompose under the action of the electric field and can be directly discharged into the atmosphere. High-voltage pulse electric field sterilization is also low-temperature and pollution-free sterilization. Ozone in the previous step is used as a medium for high-voltage pulse electric field sterilization, which is pollution-free and does not require the addition of additional preservatives, sterilizers, or pesticides, thereby ensuring the quality of fresh cut flowers while leaving no residue.

[0036] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown in a preferred embodiment 1, a method for sterilizing fresh cut flowers comprises the following steps:

[0038] Step 1: Pick the flowers 10-20 cm from the bottom of the flower;

[0039] Step 2: Prune the branches, remove the excess branches and leaves on the stems, and keep a small part of the branches and leaves for beauty;

[0040] Step 3: Pre-cooling: To preserve freshness, transfer the pruned flowers to the processing tank 1 and pre-cool them at a temperature not exceeding 4°C for 8-12 hours.

[0041] Step 4: vacuum treatment. The treatment tank 1 is vacuumed and maintained at low temperature and negative pressure for 1 to 2 hours to perform primary disinfection, vacuum insecticide and aerobic bacteria elimination.

[0042] Step 5: ozone treatment: ozone is introduced into the treatment tank 1 and maintained in the ozone environment for 30 minutes to 1 hour for secondary disinfection;

[0043] Step 6: High-voltage pulse electric field sterilization: Turn on the high-voltage pulse electric field generating device and use the high-voltage pulse electric field sterilizer to treat for 5 to 10 minutes in an ozone environment for three-level disinfection. The high-voltage pulse electric field destroys the cell membrane and completely kills the bacteria.

[0044] Step 7: ozone emission: ozone is discharged from the treatment tank 1 using an exhaust system;

[0045] Step 8: Take out the fresh cut flowers, package and sell them.

[0046] In Example 1, the fresh cut flowers are picked in step 1 and pruned in step 2 to achieve the required length and shape. The pre-cooling in step 3 inhibits the activity of enzymes by treating the flowers in a low temperature environment for a long time, thereby achieving the purpose of preserving the fresh cut flowers. In step 4, the environment in the treatment tank 1 is vacuumed and sterilized by vacuum to perform a first-level disinfection to remove aerobic bacteria and residual insects and insect eggs. In step 5, ozone treatment is performed and ozone sterilization is performed for a second-level disinfection. After the second-level disinfection, the insects, fungi, bacteria and viruses on the surface of the fresh cut flowers are greatly reduced. After all the bacteria are completely disinfected, in step six, high-voltage pulse electric field sterilization is carried out in the treatment tank 1, and high-voltage pulse electric field sterilizer is used for sterilization. Ozone is used as a medium to disinfect the residual bacteria. After three levels of sterilization, the fresh cut flowers are free of damage caused by insects, fungi, bacteria and viruses on the basis of enzyme inactivation and preservation, thereby extending the life of the fresh cut flowers and further ensuring the quality of the fresh cut flowers. In step seven, the ozone is discharged and can be directly introduced into the air. After all the ozone is discharged, the treated fresh cut flowers are taken out for packaging and sale.

[0047] As a preferred embodiment 2, the pre-cooling temperature in step 3 is 0-4°C and the pre-cooling time is 8-10 hours, thereby ensuring the pre-cooling safety effect and preventing the fresh cut flowers from being frostbitten.

[0048] As a preferred embodiment 3, the vacuum degree in step 4 is 10000-15000 Pa, and the oxygen concentration is lower than 0.5%, ensuring vacuum insecticide and sterilization.

[0049] As a preferred embodiment 4, the ozone concentration in step 5 is greater than or equal to 60 mg / m 3 The relative humidity is greater than or equal to 70%. The treatment time starts after reaching the treatment concentration, and the treatment time is 30-40 minutes. This ensures the effectiveness of ozone sterilization while preventing the color of the cut flower surface from changing due to the strong oxidizing properties of ozone.

[0050] As a preferred embodiment 5, the high-voltage pulse electric field in step 6 has an electric field strength of 17.9-18.2 kV / cm, a pulse width of 1.8-2.2 μs, and 380-420 pulses per second. This ensures the sterilization intensity of the high-voltage pulse electric field and prevents the breakdown effect during the high-voltage pulse electric field sterilization process from affecting the quality of the fresh cut flowers.

[0051] As a preferred embodiment 6, the step 2 and step 3 further include a pretreatment, and the pretreatment method is to place the base of the flower stem after pruning the fresh cut flowers in a sugar-based solution and soak it for 3 to 4 hours, the purpose of which is to improve the flowering quality, prolong the flowering period, make the flower branches harvested in the bud stage open normally, and ensure the opening quality after transportation or storage.

[0052] like Figures 2 to 6As shown, as a preferred embodiment 7, a sterilization treatment system for fresh cut flowers includes a treatment tank 1, a refrigeration device 2, a vacuum device 3, an ozone generating device 4, a high-voltage pulse electric field sterilization device 6 and an exhaust device 5, wherein the high-voltage pulse electric field sterilization device 6 is embedded in the treatment tank 1, and the refrigeration device 2, the vacuum device 3, the ozone generating device 4 and the exhaust device 5 are all arranged on the outside of the treatment tank 1, and the refrigeration end of the refrigeration device 2, the exhaust end of the vacuum device 3, the air outlet end of the ozone generating device 4 and the exhaust end of the exhaust device 5 are all connected to the reaction chamber of the high-voltage pulse electric field sterilization device 6 through corresponding connecting pipes, and the connecting pipes are provided with valves corresponding to the pipes one by one, and a plurality of mounting plates 9 are evenly spaced in the reaction chamber 7.

[0053] In Example 7, a sterilization treatment system for fresh cut flowers is provided to implement the sterilization treatment method for fresh cut flowers described above. Steps 1 and 2 are performed outside the sterilization treatment system as pretreatment of the fresh cut flowers. Starting from step 3, the flowers are treated in the sterilization treatment system. The refrigeration equipment 2, the vacuum equipment 3, the ozone generating equipment 4, the high-voltage pulse electric field sterilization equipment 6 and the exhaust equipment 5 correspond to each step. The high-voltage pulse electric field sterilization equipment 6 is placed in the treatment tank 1. The treatment tank 1 serves as a mounting frame for installing various equipment and is also used to protect the process and increase the sealing of the process. The reaction chamber 7 of the high-voltage pulse electric field sterilization equipment 6 serves as the main place for treatment. After passing through the treatment tank 1, other equipment is connected to the reaction chamber 7 of the high-voltage pulse electric field sterilization equipment 6. The fresh cut flowers treated in the first two steps are arranged in the reaction chamber 7. The fresh cut flowers are placed in order on the mounting plate 9 in the reaction chamber 7. The mounting plate 9 is arranged in order. After closing the operating door, the reaction chamber 7 cooperates to form a sealed cavity. Step 1 The three pre-cooling operations are carried out by the refrigeration equipment 2. After opening the refrigeration equipment 2 and the corresponding valve, the refrigeration equipment 2 cools down the reaction chamber 7 and maintains it for a period of time to perform the pre-cooling operation. After completing step three, the first-level disinfection of step four is carried out, and the vacuum equipment 3 is used to vacuum the reaction chamber 7 to achieve vacuum insecticide and sterilization operation. After completion, the second-level disinfection of step five is carried out, and the ozone generating equipment 4 is used to generate ozone and introduce it into the reaction chamber 7 to achieve ozone sterilization operation. After the set time is reached, the introduced ozone is not discharged, and the third-level disinfection of step six is then carried out as a medium. The high-voltage pulse generator and electrode plate of the high-voltage pulse electric field sterilization equipment 6 are used to form a high-voltage pulse electric field in the reaction chamber 7, and the fresh cut flowers are sterilized by the high-voltage pulse electric field. After three disinfections, the life and shelf life of the fresh cut flowers are extended. Then, in step seven, the exhaust equipment 5 is used to empty the residual gas in the reaction chamber 7. After the ozone concentration is within the safety factor, the door can be opened to take out the fresh cut flowers.

[0054] like Figure 6 and Figure 7As shown in a preferred embodiment 8, a plurality of mounting mechanisms are provided at equal intervals in the vertical direction within the reaction chamber 7. Each mounting mechanism comprises two L-shaped mounting frames 8 arranged opposite each other. The mounting frames 8 in the same group are symmetrical about the center of the reaction chamber 7. The L-shaped mounting frames 8 in the same group are used to form an open slot to fix the mounting plate 9, facilitating the arrangement and installation of fresh cut flowers.

[0055] As a preferred embodiment 9, the vertical section of the mounting bracket 8 is removably fixed to the side corresponding to the reaction chamber 7, and the horizontal section of the mounting bracket 8 is horizontally directed to the inside of the reaction chamber 7. The mounting brackets 8 in the same group cooperate to form a hollow bottom opening slot, each opening slot corresponding to a mounting plate 9, and the mounting plate 9 is received and fitted in the corresponding opening slot. This facilitates the fixing of the mounting plates 9 and allows the mounting plates 9 to be installed and arranged at equal intervals, facilitating the arrangement of fresh cut flowers.

[0056] like Figure 7 and Figure 8 As shown in FIG. 1 , as a preferred embodiment 10, the mounting plate 9 includes a base plate 901 that engages with corresponding opening grooves, and a plurality of strip-shaped mounting blocks 902 are arranged side by side on the base plate 901. Each mounting block 902 is provided with a plurality of mounting holes 903 at equal intervals along the extending direction of the mounting block 902. The fresh cut flowers correspond to the mounting holes 903 one by one, and the stems of the fresh cut flowers are embedded in the corresponding mounting holes 903. When arranging, the stems of the fresh cut flowers are respectively inserted into the corresponding mounting holes 903, and the buds of the fresh cut flowers are placed on the mounting blocks 902 to ensure that the flowers are separated and do not squeeze each other to affect the quality of the flowers.

[0057] As a preferred embodiment 11, the mounting block 902 is a triangular prism with an isosceles triangle bottom surface. One of the waist side surfaces of the mounting block 902 is detachably fixed to the base plate 901. The bottom side surface of the mounting block 902 is arranged upward. The mounting hole 903 is arranged obliquely in the mounting block 902, and the mounting hole 903 passes through one waist side surface and exits from the other waist side surface. The inclination angle of the mounting hole 903 is the same as the inclination angle of the bottom side surface of the mounting block 902. When arranging, the fresh cut flowers are placed at an angle, and the stems are inserted through the mounting holes 903 and are then tilted between the intervals of adjacent mounting plates 9, and the flower buds are placed on the bottom side surfaces of adjacent mounting blocks 902. On the one hand, this saves the height required for arranging the stems of the fresh cut flowers and reduces the intervals between the mounting plates 9, so that more mounting plates 9 can be installed at one time and more fresh cut flowers can be processed. On the other hand, the flower buds are placed at an angle on the bottom side surfaces of the previous mounting block 902 to ensure that the flower buds and the stems are not separated or broken, and to prevent all forces from being concentrated on the junction between the flower buds and the stems, causing deformation of the flower buds.

[0058] As a preferred embodiment 12, the vertex angle of the isosceles triangle on the bottom surface of the mounting block 902 does not exceed 90 degrees, and adjacent mounting blocks 902 are arranged side by side in the same direction, with the bottom angle of the preceding mounting block 902 in contact with the vertex angle of the following mounting block 902. The stems of the fresh cut flowers are obliquely embedded in the mounting holes 903, and the buds of the fresh cut flowers are arranged on the bottom side of the preceding mounting block 902. This ensures that the fresh cut flowers are arranged properly, and that the arranged fresh cut flowers are slightly lifted, without excessively squeezing the buds near the bottom side. This also ensures that the force on the fresh cut flowers is distributed by the bottom side and is not concentrated at the junction of the buds and the stems.

[0059] As a preferred embodiment 13, the treatment tank 1 has a retractable sealed door on one side. An installation space is provided within the treatment tank 1, and the high-voltage pulse electric field sterilization device 6 is removably placed within the installation space. After opening the door, the fresh cut flowers to be treated are placed into the reaction chamber of the high-voltage pulse electric field sterilization device 6. The reaction chamber serves as the treatment area, and the treatment tank 1 is used to enhance sealing during the process and facilitate the installation of various devices. The high-voltage pulse electric field sterilization device 6 is used to perform step 6.

[0060] As a preferred embodiment 14, the refrigeration device 2 and the vacuum device 3 are located on both sides of the top of the processing tank 1. The cooling end of the refrigeration device 2 and the vacuum device 3 extend through the processing tank 1 and the top of the high-voltage pulse electric field sterilization device and the reaction chamber, ensuring the operation of steps 3 and 4.

[0061] As a preferred embodiment 15, the ozone generator 4 is located on one side of the treatment tank 1. The ozone generator 4 generates ozone by decomposing hydrogen peroxide. The outlet of the ozone generator 4 passes through the treatment tank 1 and the high-voltage pulse electric field sterilization device and is sealed and connected to the side of the reaction chamber. This ensures the operation of step 5.

[0062] As a preferred embodiment 16, the exhaust device 5 is located at the bottom of the treatment tank 1, and the exhaust end of the exhaust device 5 passes through the treatment tank 1 and the high-voltage pulse electric field sterilization device and is sealed and connected to the bottom of the reaction chamber to ensure the operation of step 7.
