[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figure 1 This embodiment provides a fresh cut flower cold sterilization device, including an insulation box 1, a conveying device 2, a negative ion generating device 3, a refrigeration device and an atomizing device 4.

[0024] The insulated box 1 is made of a 7mm to 10mm thick polystyrene board, with a length of 2m to 3m, a width of 1m to 2m, and a height of 1m. The left and right sides of the insulated box 1 connected to the conveying device 2 are respectively provided with upwardly opening flip doors, and the flip doors are located above the conveying device 2. When the conveying device 2 conveys fresh cut flowers, the flip doors are folded upward and opened; when the conveying device 2 stops running, that is, the fresh cut flowers are pre-cooled and antiseptic treated in the insulated box 1, the flip doors are folded downward and closed to prevent a large amount of cold air in the insulated box 1 from flowing out.

[0025] The conveying device 2 passes through the interior of the heat preservation box 1, and the fresh cut flowers enter the heat preservation box 1 through the conveying device 2. The conveying device 2 includes a conveyor belt 21, and baffles 22 are installed on both sides of the conveyor belt 21 to prevent the fresh cut flowers from falling during the conveying process.

[0026] The refrigeration device comprises an outdoor unit 5 located outside the heat preservation box 1 and an evaporator 6 located inside the heat preservation box 1 , and has a refrigeration capacity of 3Kw to 4Kw. Cold air is blown into the heat preservation box 1 through the air outlet of the evaporator 6 to cool the fresh cut flowers in the heat preservation box 1 .

[0027] The output end of the negative ion generator 3 is connected to the incubator 1. The negative ion concentration generated by the negative ion generator 3 is 5 to 10×106 / cm 3 The emission mode is carbon fiber or steel needle, and the output voltage is 3.0KV~6.5KV, which is used to perform negative ion antiseptic treatment on the fresh cut flowers in the incubator 1.

[0028] The output end of the atomizing device 4 is connected to the incubator 1. The device adopts ultrasonic atomization, with a humidification capacity of 3 kg / h and a particle size of atomized particles of 5 μm to 10 μm. When in use, a preservative solution is added to the atomizing device 4. Specifically, a chlorine dioxide solution can be added to the atomizing device 4 to perform atomization, moisturizing and antiseptic treatment on the fresh cut flowers in the incubator 1.

[0029] The working process of the fresh cut flower cold sterilization device of this embodiment:

[0030] Step 1: Start the refrigeration device, add the preservative solution into the atomizing device 4, and open the flip door of the thermal insulation box 1;

[0031] Step 2: placing the fresh cut flowers at the input end of the conveying device 2 and conveying them into the incubator 1, the conveying device 2 stops running, and the flip door is closed;

[0032] Step 3: The atomization device 4 and the negative ion generating device 3 are started synchronously, and the preservative atomization and negative ion preservative treatment are started for 5 minutes to 10 minutes. After the treatment is completed, the fresh cut flowers are output and the next step of storage or packaging is carried out.

[0033] During the whole treatment process, the refrigeration device is kept started, and the temperature of the treatment process is controlled at 4-5°C. After about 800-1000 branches of fresh cut flowers fill the incubator 1, the preservative ultrasonic atomization and negative ion preservative treatment are started.
