Description

[0002] Dendrobium nobile, a high-end orchid cut flower, is highly sought after in the market for its upright stems, vibrant colors, and long vase life. The post-harvest pretreatment process directly determines its commercial value and shelf life, especially key processes such as stalk hardening, flower opening control, and post-harvest physiological damage repair. Currently, Dendrobium nobile pretreatment generally relies on general-purpose cold storage or simple processing rooms. The pretreatment stage of Dendrobium nobile cut flowers requires strict control of temperature, humidity, and light conditions. However, the current pretreatment environment for Dendrobium nobile cut flowers has the following shortcomings: it does not consider the different maturity levels of Dendrobium nobile cut flowers at the time of harvest and the different processing stages, such as pre-cooling, conditioning, and rehydration, which have different requirements for environmental parameters; all Dendrobium nobile cut flowers are placed in the same pretreatment room after harvesting, and environmental parameters are uniformly adjusted and controlled.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0045] Example 1
[0046] like Figure 2As shown, a pretreatment chamber for Dendrobium officinale cut flowers that can precisely control the environment is provided with partitions 6 in the treatment chamber 1. The partitions 6 are arranged at equal intervals to divide the treatment chamber 1 into several separate pretreatment areas. In this embodiment, the treatment chamber 1 is divided into four pretreatment areas.
[0047] Each pretreatment zone is equipped with a separate temperature control unit for individually regulating and controlling the temperature environment within that zone.
[0048] For example, the temperature control components described above can be a central air conditioning system or a combination of a hot air blower and an exhaust fan to achieve the purpose of temperature regulation;
[0049] like Figure 2 as well as Figure 3 As shown, the temperature control component in this embodiment consists of a heating component and a cooling component;
[0050] like Figure 3 As shown, the heating component is set as underfloor heating 10. Each pretreatment zone is equipped with a separate underfloor heating 10, and each underfloor heating 10 is equipped with a separate control component. The underfloor heating 10 and its control component are existing technologies. Those skilled in the art are able to select between residential and commercial underfloor heating as needed, and know the connection between the components in the underfloor heating system and the installation and control of the control component.
[0051] like Figure 2 As shown, the cooling component includes: a wet curtain 7, with two wet curtains 7 installed in each pretreatment zone, each wet curtain 7 positioned against one of the two side walls of the pretreatment zone; the wet curtain 7 is an existing component, with several honeycomb-shaped through holes on it, and each of the two wet curtains 7 in each pretreatment zone is equipped with an independent water circulation system, with several honeycomb-shaped through holes on the wet curtain 7, forming a water curtain on the wet curtain 7 through the water circulation system; the connection between the wet curtain 7 and the water circulation system is prior art known to those skilled in the art, and will not be described in detail here;
[0052] like Figure 3 As shown, an exhaust fan 9 is installed on one side wall of each pretreatment zone, and an intake fan 8 is installed on the other side wall of the pretreatment zone. The exhaust fan 9 is responsible for exhausting the air in the pretreatment zone to the outside, and the intake fan 8 is responsible for drawing the outside air into the pretreatment zone. The intake fan 8 draws the outside air with a higher temperature into the room. The air flows through the water curtain on the wet curtain 7. The water curtain absorbs the heat in the air, which significantly reduces the temperature of the air entering the room. The cooled air enters the room to achieve the purpose of cooling.
[0053] Each pretreatment zone is equipped with an independent ultrasonic atomization component, and the generated atomized water vapor can regulate the humidity environment within the pretreatment zone;
[0054] The aforementioned ultrasonic atomizing component belongs to the prior art, which converts liquid into micron-sized mist particles through ultrasonic high-frequency vibration; those skilled in the art are capable of purchasing existing ultrasonic atomizing equipment or ultrasonic atomizing components and assembling them into a complete ultrasonic atomizing component; the detailed structure of ultrasonic atomization will not be described in detail here.
[0055] Each preprocessing zone is equipped with an individual, controllable lighting adjustment component to regulate the lighting within that zone;
[0056] For example, the light adjustment component can be set as a shading film on the roof. When the shading film is rolled up, the outside light can fully illuminate the pretreatment room; when the shading film is unfolded and covers the roof, the intensity of the light can be reduced or even completely blocked, depending on the color depth of the shading film.
[0057] like Figure 1 As shown, in this embodiment, a light-scattering film 3 is installed on the roof 2. The light-scattering film 3 can convert direct light into scattered light, which avoids the scorching of flowers and leaves by direct light and shortens the flowering period for Dendrobium officinale cut flowers.
[0058] like Figure 1 As shown, the light adjustment component of this embodiment is installed on the roof 2 of the pretreatment room, including: a light-shielding curtain roller 4 and a light-shielding curtain 5. Two sets of light-shielding curtain rollers 4 are installed on the roof 2 of each pretreatment area. The light-shielding curtain 5 is wound inside the light-shielding curtain roller 4. A counterweight roller is installed on the edge of the tail end of the light-shielding curtain 5. The counterweight roller needs to have a certain weight. When the light-shielding curtain 5 is unfolded, it can help to drive the light-shielding curtain 5 to unfold downwards. The counterweight roller with a certain weight can also prevent the light-shielding curtain 5 from being blown away and rolled up by the wind.
[0059] The two sets of light-blocking curtains 5 unfold inside the roller 4 and unfold to the sides of the canopy 2 respectively, which can completely cover the canopy 2.
[0060] like Figure 5 As shown, a winding shaft 404 is provided inside the blackout curtain roller 4. The first end of the winding shaft 404 is provided with a driven gear 403 and is rotatably disposed on one side of the blackout curtain roller 4; the second end of the winding shaft 404 is rotatably disposed on the other side of the blackout curtain roller 4.
[0061] Inside the light-shielding curtain roller 4, there is also a drive gear 402, which meshes with the driven gear 403; a motor rotor is set at the center of the drive gear 402, and the drive gear 402 rotates under the drive of the motor 401.
[0062] The light-shielding curtain 5 is rolled up and stored on the winding shaft 404. The driving gear 402 drives the driven gear 403 to rotate in the forward or reverse direction. The driven gear 403 drives the winding shaft 404 to rotate in the forward or reverse direction. The light-shielding curtain 5 unfolds or is rolled up and retracted. When the light-shielding curtain 5 is unfolded, the light intensity entering the pretreatment area can be reduced or even blocked depending on the light transmittance of the light-shielding curtain 5.
[0063] Depending on the maturity and appearance of the Dendrobium officinale cut flowers at the time of harvest, or according to different stages of pretreatment, they are processed in different pretreatment zones. Environmental parameters are regulated separately in each pretreatment zone. Compared with the current undivided pretreatment mode, the environmental regulation and control is more precise, which is conducive to extending the vase life of cut flowers and improving the appearance of the finished product.
[0064] Example 2
[0065] Based on Example 1, Example 1 addresses the problem that the current pretreatment of Dendrobium officinale cut flowers does not involve targeted environmental control and therefore lacks precision. In Example 1, the environmental parameter control in different pretreatment zones is actually set manually. Based on a large amount of data, the environmental parameters suitable for different maturity levels of cut flowers or different pretreatment stages of cut flowers are obtained, and the control is carried out according to these environmental parameters.
[0066] In this embodiment, a biogas sensor and a weight sensor are set in each pretreatment zone; the current state of Dendrobium officinale cut flowers in the current pretreatment zone is monitored in real time. Based on the current state as the reference benchmark, dynamic environmental parameter adjustment and matching are performed on the basis of large model calculation to further improve the controllability accuracy.
[0067] The biogas sensors are deployed at multiple points in the pretreatment area to non-destructively monitor the respiration intensity and ethylene release concentration of Dendrobium officinale cut flowers from multiple directions. Weight sensors are installed on the flower racks, with the weight sensors positioned on the contact surface between the racks and the cut flowers. The biogas sensors and weight sensors are communicatively connected to the input of a microprocessor, and the output of the microprocessor is communicatively connected to the control of the air intake fan 8, exhaust fan 9, and underfloor heating 10 in the temperature control component, the ultrasonic power control unit of the ultrasonic atomization component, and the motor 401 inside the shading curtain roller 4 in the light adjustment component.
[0068] The purpose of monitoring the weight difference of cut flowers by using a weight sensor is to reflect the water loss rate of the cut flowers. By monitoring the respiration intensity and water loss rate of the cut flowers, the physiological state of the cut flowers can be analyzed in real time. Based on the current real-time physiological state of the cut flowers, dynamic environmental parameter regulation can be carried out to adjust the environmental parameters to the optimal parameter combination.
[0069] Example 3
[0070] Based on Example 1, under normal circumstances, the CO2 and O2 regulation in the pretreatment room of Dendrobium officinale cut flowers is carried out by continuous constant atmosphere, that is, a constant amount of CO2 and O2 is continuously introduced over a period of time to regulate the photosynthesis and respiration of the cut flowers.
[0071] This embodiment adopts a dynamic pulse modified atmosphere method, in which a set of dynamic pulse modified atmosphere components are set in each pretreatment zone, which can generate periodic short-term, high-intensity pulse gas; compared with continuous constant modified atmosphere, it has a more obvious preservation effect and can reduce the potential stress of fresh cut flowers caused by long-term exposure.
[0072] The dynamic pulse atmosphere control unit includes:
[0073] An oxygen generator and a carbon dioxide generator are included; the oxygen generator and the carbon dioxide generator are connected to the output of a microprocessor; the input of the microprocessor is connected to a timer; by setting the duration of pulse gas generation and the periodic interval of pulse gas generation, periodic short-duration high-intensity gas pulses are generated, such as generating high-concentration CO2 low-oxygen pulses, which helps the respiration of cut flowers.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
