Description

[0001] The present application relates to the technical field of fresh flower processing equipment, and particularly relates to a fresh petal preservation device. BACKGROUND

[0002] After picking, the petals of fresh flowers are prone to wilting and discoloration due to water loss and oxidation, which seriously affects the economic value of fresh flowers. In order to prolong the shelf life of fresh petals, the existing technology usually sprays a preservative on the petals after picking, which forms a protective film on the surface of the petals to reduce water loss and inhibit oxidation.

When the fresh petals are conveyed to the upper end of the flexible plastic mesh chain conveying plate, they naturally fall into the feed hopper of the preservative treatment assembly, the entering of the fresh petals is in a ratio of 1:6 to the air volume, which ensures that the petals in the feed can be fully turned over, avoids the accumulation of petals leading to uneven contact with the preservative, and also avoids the waste of energy consumption or damage to the petals due to excessive air volume, and then the petals enter the mixing tank. At the same time, the fan one provides high-pressure airflow for the siphon type atomizing nozzle through the air inlet pipe, and the preservative in the water tank is atomized by the siphon type atomizing nozzle under the action of high-pressure airflow and uniformly sprayed onto the fresh petals in the mixing tank. The airflow generated by the fan two is conveyed to the inside of the mixing tank through the adjusting pipe and the air outlet pipe, and the air outlet is inclined upward along the mixing tank wall at an angle of 45°-50°, so that the suspended state of the fresh petals rotates in the tank body, drives the fresh petals in the mixing tank to fully turn over, so that each petal can uniformly contact with the atomized preservative, and the preservative treatment effect is ensured. The fresh petals that have completed the preservative treatment move downward along the inner wall of the mixing tank under the action of the inclination angle of the mixing tank, fall into the conveying belt two of the discharging assembly through the discharge hopper, and the conveying belt two is driven by the drive motor three to run, and the triangular structure formed by the conveying shaft three, the conveying belt shaft four and the conveying belt shaft five ensures stable conveying, and finally the fresh petals that have completed the preservative treatment are conveyed to the designated collection device.

[0028] During the working process, the air outlet amount of the air outlet pipe can be controlled by adjusting the air volume adjusting valve to adapt to the processing needs of different types and different quantities of fresh petals, and to ensure the versatility and processing effect of the equipment.

[0029] In the above process, the automatic conveying and spraying structure is adopted, continuous operation of the fresh flower petals from feeding, preservation treatment to discharging is realized, labor intensity is greatly reduced, work efficiency is improved, and uneven problems caused by manual spraying are avoided; in the preservation treatment assembly, the siphon type atomizing nozzle cooperates with the fan to realize efficient atomization of the preservative, the fan two cooperates with the inclined air outlet pipe to drive the fresh flower petals to fully turn in the mixing box, ensure that each petal can be uniformly contacted with the atomized preservative, significantly improve the utilization rate of the preservative and the preservation effect of the fresh flower petals, and the petals are not damaged in the mixing and turning process; the inclination angle, length-width ratio of the mixing box and inclination angle of the air outlet of the air outlet pipe are all optimized and designed to ensure that the fresh flower petals have sufficient residence time and turning effect in the mixing box, and further ensure the uniformity and sufficiency of the preservation treatment.
