The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0021] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.
[0022] The following is in conjunction with the appendix Figures 1-2 The present invention provides a detailed description of a fresh fruit and vegetable preservation device combining pulsed light technology and a composite preservative, which includes: a cabinet 1.
[0023] Specifically, the cabinet 1 is equipped with a shelf 11 for placing fruits and vegetables, a xenon lamp 12 is installed on the inner wall of the cabinet 1 to provide pulsed light to the fruits and vegetables, a preservative liquid circulation pipe 13 is installed on the inner wall of the cabinet 1 to spray preservative liquid on the fruits and vegetables, a fan 14 is installed on the cabinet 1 to circulate air inside and outside the cabinet 1, and a control panel 16 is installed on the cabinet door 15 of the cabinet 1 to adjust the preservation mode of the refrigeration cabinet.
[0024] In other words, using the xenon lamp 12 to subject fruits and vegetables to short-term, high-intensity radiation can quickly kill bacteria, mold, and other microorganisms while avoiding damage to the quality of the fruits and vegetables. In addition, combined with a compound preservative, the preservation effect is further enhanced, playing a role in anti-oxidation, anti-rot, and pest prevention, significantly extending the shelf life of fruits and vegetables. The fan 14 enhances the air circulation inside and outside the cabinet 1, thereby allowing the preservative liquid sprayed on the fruits and vegetables to dry and form an antibacterial protective layer on the surface of the fruits and vegetables, further improving the preservation effect of the fruits and vegetables.
[0025] Therefore, the xenon lamp 12 sterilizes fruits and vegetables with pulsed light, the preservation liquid is sprayed onto the fruits and vegetables through the preservation circulation pipe, and the fan 14 circulates air inside and outside the cabinet 1 to dry the preservation liquid on the fruits and vegetables. The control panel 16 regulates the xenon lamp 12, the preservation liquid, and the drying time, forming a reasonable and orderly combined system control, thereby leaving a long-lasting antibacterial protective layer on the surface of the fruit and extending its shelf life. This fresh fruit and vegetable preservation cabinet has a simple structure, can efficiently sterilize fruits and vegetables, degrade pesticide residues, and extend the shelf life of fruits and vegetables.
[0026] Optionally, fans 14 are located at the top and rear of cabinet 1. Understandably, this arrangement facilitates air circulation inside and outside cabinet 1, thereby accelerating the drying speed of the preservative solution on fruits and vegetables, allowing a protective layer to quickly form on the surface of the fruits and vegetables, thus promoting freshness. Specifically, there can be four fans 14 at the rear of cabinet 1, two fans 14 at the top of cabinet 1, and four fans 14 on the cabinet door 15. The two top fans 14 can exhaust air outwards, while the other eight fans 14 blow air inwards.
[0027] Optionally, the preservative circulation pipe 13 is located between the shelf 11 and the cabinet door 15, and surrounds the placement entrance of the shelf 11. Understandably, this arrangement facilitates thorough spraying of the preservative solution onto the fruits and vegetables on the shelf 11, thereby improving the preservation effect. The preservative circulation pipe 13 may be square-shaped to match the cabinet body 1.
[0028] Optionally, the shelf 11 has multiple perforated partitions 111, which create multiple storage spaces, each equipped with a xenon lamp 12. Understandably, the multiple perforated partitions 111 facilitate the creation of multiple storage spaces for fruits and vegetables, allowing more of the outer surface of the fruits and vegetables to be exposed for thorough spraying with preservative solution, while also improving air circulation. The xenon lamp 12 in each storage space ensures sufficient pulsed light irradiation of the fruits and vegetables on each layer, resulting in better sterilization. The xenon lamp 12 can be elongated tubular, and four xenon lamps 12 can be installed around the perimeter of each storage space.
[0029] Furthermore, the partition 111 is made of stainless steel. Understandably, this design facilitates a longer service life for the partition 111 and also makes the processing of the perforated areas easier. The perforations in the partition 111 can be in a grid pattern, and the number of partitions 111 can be four.
[0030] Furthermore, the preservative circulation pipe 13 is equipped with a spray head 131 and a liquid inlet 132. The spray head 131 extends into each placement space to spray the fruits and vegetables, and the liquid inlet 132 is located outside the cabinet 1 to replenish the preservative liquid in the preservative circulation pipe 13. Understandably, by extending the spray head 131 into each placement space to spray the fruits and vegetables, it is convenient to ensure sufficient preservative spraying on each layer of fruits and vegetables; the liquid inlet 132 facilitates the replenishment of preservative liquid into the preservative circulation pipe 13. Specifically, the spray head 131 in the top placement space can be located at the top of the cabinet 1, and there can be two of them. The spray heads 131 in each placement space can extend into the placement space from the left and right sides for a certain distance. The liquid inlet 132 can be located at the top of the cabinet 1 and extend into the cabinet 1 to connect with the preservative circulation pipe 13.
[0031] Optionally, the control panel 16 features a xenon lamp mode 12, a preservation liquid mode, and a drying mode. Understandably, these settings facilitate switching between the xenon lamp mode 12, the preservation liquid mode, and the drying mode. Individual modes can be freely selected for use, or they can be used in combination, making the refrigerator more flexible in its use. It is not only suitable for post-harvest preservation of fruits and vegetables but can also be widely applied in agricultural product planting bases, primary processing enterprises, and many other fields. The control panel 16 also allows setting the working time for each operating mode.
[0032] Optionally, the bottom of the inner wall of the cabinet 1 is equipped with a floor drain 17 to receive excess preservative liquid after spraying. The floor drain 17 is connected to the liquid inlet 132. Understandably, the floor drain 17 facilitates the collection of excess preservative liquid, which then flows from the floor drain 17 into the liquid inlet 132 and into the preservative liquid circulation pipe 13, ensuring that the sprayed preservative liquid can be circulated in a timely manner and avoiding waste. The preservative liquid collected by the floor drain 17 can be pumped into the liquid inlet 132.
