Description

Technical Field

[0001] This invention relates to the field of agricultural cultivation facilities technology, and in particular to a softened chicory cultivation system and its construction method. Background Technology

[0002] Softened chicory is a bulb product produced through a two-stage cultivation process: chicory root cultivation and shading softening. The first stage involves open-air cultivation of chicory to form fleshy roots, which can then be stored at low temperatures for 4-6 months after harvesting. The second stage involves placing the fleshy roots in a dark environment and softening them in stages and batches using hydroponics, soil cultivation, or vertical cultivation methods. The softening process is completed when the roots are grown for 30-40 days at 85%-95% humidity and 12℃-15℃, or for 20-25 days at 18℃-20℃, forming milky bulbs.

[0003] After obtaining the fleshy roots in the first stage, the stored chicory fleshy roots need to be kept in a low-temperature, high-humidity environment of 0℃~4℃ and above 90% humidity. Due to the characteristic of multiple batches of softening and cultivation after a single harvest, a large quantity of fleshy roots needs to be stored, requiring a large storage space that meets stable temperature and humidity conditions. Simultaneously, due to the uncertainty of market forecasts when selling the bulbs, a certain number of bulbs may not be sold in time. In this case, they need to be temporarily stored at low temperatures to keep them essentially dormant, allowing sufficient time for secondary sales and preventing them from losing their commercial value due to a lack of storage conditions.

[0004] Existing cultivation systems suffer from several drawbacks. First, they cannot easily adjust the softening cycle according to changes in market demand, or require significant energy consumption and high costs, thus lacking adaptability to market changes and failing to maximize profits. Second, existing cultivation systems do not adequately consider low-energy-consumption overall design, which has a substantial impact on daily operating costs. This results in enormous energy consumption for temperature control during the softening process, leading to soaring costs. Furthermore, the strong coupling between the cultivation system and external environmental temperature changes means that the load on heating and cooling equipment is greatly affected by the external environment, causing the entire system to be in an uncertain and volatile state, resulting in poor reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a chicory cultivation system and its construction method. After the cultivation system is built, the temperature of each functional space in the cultivation room can be regulated by storing natural cold and collecting solar heat within the designed system structure framework, thereby solving the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A softened chicory cultivation system includes a cultivation chamber, in which a heat storage section, a cold storage section, and a cultivation section are respectively provided. The cultivation section has multiple partition walls arranged in a U-shape or ring structure from the inside to the outside. The centers of the multiple partition walls are located on the same axis, and a cultivation space is formed between two adjacent partition walls.

[0008] The heat storage section collects heat generated by sunlight to provide a heat source for the cultivation section, while the cold storage section stores cold energy through heat pipes to provide a cold source for the cultivation section. This keeps the various functional spaces in the cultivation room (including the cultivation section, the fleshy root storage room, and the temporary bud storage room, where a portion of the cultivation section can be independently separated as the fleshy root storage room and the temporary bud storage room) within a preset temperature range and forms a temperature gradient. The temperature gradient is set according to the temperature corresponding to the storage of fleshy roots, the temporary storage of buds that have not been sold in time, and the expected softening period of each cultivation part in the cultivation room.

[0009] Furthermore, the system is configured to independently regulate the temperature within each of the functional spaces via the heat source of the heat storage unit and the cold source of the cold storage unit.

[0010] Furthermore, the cold storage section is located at the bottom of the cultivation room, and a water tank is installed in the cold storage section. The cold source stored in the cold storage section is obtained by the evaporation section of the heat rod absorbing the heat of the water in the water tank and gradually forming ice. When the functional space in the cultivation room needs to be cooled, the cold source stored in the cold storage section is put into the required functional space.

[0011] The heat storage unit is located on the top of the cultivation room. Pipes connected to the heat storage unit and arranged in a serpentine pattern are installed in each functional space of the cultivation room, so that the heat source in the heat storage unit flows to each functional space of the cultivation room through the pipes, thereby raising the temperature of each functional space of the cultivation room.

[0012] Furthermore, in southern regions where winter temperatures remain relatively high, all functional spaces within the cultivation chamber are situated on the same plane, with heat pipes positioned at the center of the cultivation chamber. The heat pipes are installed vertically, with their condenser sections extending out of the cultivation chamber to contact the outdoor air, and their evaporator sections placed within the cold storage section.

[0013] Furthermore, in southern regions where winter temperatures remain high, vortex tubes are installed at the condenser section of the heat pipes. The cold air output end of the vortex tubes blows air to cool the condenser sections of the centrally arranged heat pipes, creating a temperature difference between the condenser and evaporator sections of the heat pipes, and causing the local area near the condenser section of the heat pipes to drop below 0°C.

[0014] Furthermore, in northern regions where winter temperatures drop below 0°C, all functional spaces within the cultivation chamber are on the same plane, with heat pipes arranged around the outer perimeter of the cultivation chamber; and the heat pipes are installed vertically, with their condensation section in contact with outdoor air and their evaporation section placed in the cold storage section.

[0015] Furthermore, the cultivation room is equipped with a lifting passage in the center for people and goods to enter and exit; an air flow channel is fixed to the outer edge of the lifting passage, and the air exchange between the inside and outside of the cultivation room is controlled by opening and closing the ventilation window at the top of the air flow channel.

[0016] Furthermore, the partition wall is configured to be constructed using a double layer of concrete fabric, with polyurethane foam or other lightweight insulation material filling the space between the two layers of concrete fabric.

[0017] Furthermore, hooks are arranged at preset intervals on the upper part of the concrete fabric so that the concrete fabric is clamped by the hooks; through nails are arranged between the two layers of concrete fabric according to a preset area, and the through nails are distributed in a triangular wave shape or in a sine or cosine wave shape.

[0018] The present invention also provides a construction method for a cultivation system, applied to the above-mentioned cultivation system, comprising the following steps:

[0019] S1. Excavate a construction space at a preset location that can accommodate the cultivation room. The construction space is a cavity formed by the space excavated below the ground level and the space above the ground level. The earthwork of the part of the cavity above the ground level is formed by the dike formed by piling the earthwork excavated in the construction space along its circumference.

[0020] S2. In southern regions where winter temperatures remain relatively high, the cold storage unit should be located in the central area of ​​the bottom of the cultivation chamber, excavated to a sufficient depth to achieve a suitable volume and store adequate cooling capacity. A lifting channel and a surrounding airflow channel should be installed above the cold storage unit. The remaining spaces in the cultivation chamber, at the same level as the top of the cold storage unit, should be designated as the cultivation section, a fleshy root storage chamber, and a temporary bud storage chamber. In northern regions where winter temperatures drop below 0°C, the cold storage unit should be installed around the outer edge of the cultivation chamber. The bottom of the cold storage unit can be level with or slightly lower than the bottom of the rest of the cultivation chamber. A lifting channel and a surrounding airflow channel should be installed in the central area of ​​the cultivation chamber. The remaining spaces in the cultivation chamber should be designated as the cultivation section, a fleshy root storage chamber, and a temporary bud storage chamber.

[0021] S3. Use double-layer concrete cloth to construct partition walls in the cultivation section, and fill the space between the two layers of concrete cloth with polyurethane foam or other lightweight insulation materials to form a cultivation space with a U-shaped or ring-shaped structure.

[0022] S4. A cooling pool is installed below the ground level of the cultivation space. The bottom and sides of the cooling pool are waterproofed. The cooling pool is separated from the cultivation space by a floor that serves as radiant cooling.

[0023] S5. Arrange the heat pipes in the center of the cultivation room or around the outer perimeter of the cultivation room; install the heat pipes vertically, with the evaporation part placed in the cold storage part and the condensation part extending out of the cultivation room and in contact with the outdoor air. In the case of southern regions where the winter temperature is still high, vortex tubes are installed at the condensation parts of each heat pipe, and the cold air output end of the vortex tube blows air to the condensation parts of each heat pipe to cool them down, so that the local area near the condensation part of the heat pipe is below 0°C.

[0024] S6. A heat storage unit is set above the cultivation unit, and heat is transferred between the heat storage unit and the cultivation space through a solenoid valve and a serpentine pipe arrangement. A high-density brine pool is set inside the heat storage unit, and a high-transmittance PC sun panel is set at the top of the heat storage unit.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] (1) This invention independently regulates the temperature of each functional space in the underground cultivation chamber by storing natural cold energy and collecting solar heat through the setting of cold storage and heat storage sections. Each functional space in the cultivation chamber includes not only cultivation sections with independently adjustable temperatures (thus determining the softening period), but also fleshy root storage chambers and temporary bud storage chambers, thus eliminating the need for additional cold storage and transportation links; using the excavated soil as a cofferdam reduces the excavation depth of the cultivation chamber, reducing the amount of work and construction costs; at the same time, it utilizes the constant temperature characteristics of the underground environment to minimize the operating cost of the cultivation system with extremely low energy consumption;

[0027] (2) Heat is stored in the form of water and cold is stored in the form of ice. By dissolving a certain amount of ice in water, the temperature of the water in the cooling pool is adjusted, thereby adjusting the radiative cooling. Since there is a temperature gradient in each functional space of the cultivation room and the required temperature is different, each functional space in the cultivation room can independently achieve its own temperature control purpose by radiating different amounts of cold in this way, while also utilizing the characteristic of water having a large specific heat capacity;

[0028] (3) By utilizing the spatial temperature gradient characteristics, the functions of storing fleshy roots, temporarily storing buds, and adjusting the different softening cycles of various cultivation parts can be realized. This allows for the control of the start time, softening cycle, and market launch time of softening cultivation according to market demand, thereby maximizing economic benefits.

[0029] (4) By utilizing the cold storage unit to store cold energy and the heat storage unit to store heat energy, the system can provide cold and heat energy for temperature regulation of various functional spaces in the cultivation room at any time and in any place. Moreover, since the cold and heat energy are designed in one go, that is, after the system is constructed, no additional costs will be incurred in subsequent operation, thereby reducing daily operating costs.

Detailed Implementation

[0037] The technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0038] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] Example 1

[0040] In this embodiment, as Figures 1 to 2As shown, a cultivation system is provided that is suitable for southern regions where winter temperatures are still relatively high. The system includes a cultivation chamber 100, which is a cavity formed by a space excavated below ground level 200 and a space above ground level 200. The dike 300 formed by the space above ground level is formed by piling up the excavated soil below ground level to reduce the loss of cold air in the space above ground level of the cultivation chamber 100 and to reduce the amount of soil that needs to be excavated.

[0041] The cultivation chamber 100 includes a cold storage section 101, a cultivation section 102, and a heat storage section 103. The cold storage section 101 is located at the central axis of the bottom of the cultivation chamber and extends vertically downwards to achieve a larger space within a relatively small planar area. The cold storage section 101 is a relatively enclosed space containing a water tank (not shown in the figure). Heat pipes 1011 are installed vertically, with their tops (condensation sections) extending out of the cultivation chamber and in contact with the outside air, and their bottoms (evaporation sections) placed in the water tank of the cold storage section 101. As the heat pipes 1011 rapidly transfer heat, the water in the cold storage section gradually turns into ice.

[0042] The heat pipe 1011 is filled with a low-boiling-point medium. Whenever the outside air temperature is lower than the temperature at the bottom of the heat pipe 1011, the medium, driven by the temperature difference, transfers the heat absorbed from the evaporation section to the top. After contacting the cold outdoor air, the condensation section releases heat and condenses into liquid, flowing back to the bottom. This cycle repeats, dissipating the heat in the cold storage section 101 to the ground surface, gradually lowering the temperature of the water pool inside and causing it to freeze into ice blocks. The ice blocks stored in the cold storage section can be accessed at any time through the ice collection port 1012. The stored cold energy can control the temperature of each functional space within the cultivation chamber 100 (including the cultivation section, the fleshy root storage chamber, and the temporary bud storage chamber), achieving a cooling effect in each functional space.

[0043] In southern regions, winter temperatures are often above 0°C. Therefore, it is necessary to centrally install vortex tubes (not shown in the figure) next to the condenser section of the heat pipes, and to blow air from the cold air output end of the vortex tubes to cool down the condenser sections of each heat pipe, so that the local area near the condenser section of each heat pipe is below 0°C. This creates a temperature difference between the condenser section and the evaporator section, causing the heat pipe 1011 to work and gradually turning the water in the water tank of the cold storage section 101 into ice.

[0044] like Figure 1As shown, the cultivation section 102 is located in the peripheral space above the relatively enclosed cold storage section 101. Multiple partition walls 1021 with a U-shape or ring structure are arranged sequentially from the inside to the outside. The centers of the multiple partition walls are located on the same axis, and a cultivation space 1022 is formed between two adjacent partition walls 1021. In the cultivation space, the chicory fleshy roots to be softened can be placed in a multi-layer three-dimensional shelf manner to soften them in a suitable temperature range.

[0045] Furthermore, a cooling pool 1023 is installed beneath the floor of the cultivation space 1022. The cooling pool 1023 is isolated from the cultivation space 1022 by the floor, thus forming a relatively sealed chamber. Simultaneously, an ice inlet 1024 is provided on the floor of the cultivation space 1022. When ice stored in the cold storage section 101 is taken and added to the cooling pool 1023 through the ice inlet 1024, the water temperature is adjusted by melting the ice, thereby regulating the amount of cold radiated into the cultivation space.

[0046] This method of adjusting temperature by adding ice to water can also be used to generate high-pressure mist through atomizing nozzles for temperature and humidity control during the storage of fleshy roots, preventing them from freezing below 0°C. Similarly, it can be used for the temporary storage of unsold buds.

[0047] The cultivation section 102 forms independent cultivation spaces 1022 with a U-shape or ring structure through the partition wall 1021. Therefore, each independent cultivation space 1022 can adjust the water temperature in the cooling pool 1023 by adjusting the amount of ice added, thereby radiating different amounts of cold to achieve the purpose of independent temperature control.

[0048] The cultivation space 1022 is distributed in a concentric "U" or "ring" structure, with the temperature gradually increasing from the inner to the outer rings in southern regions. This allows the cooling storage unit 101, located in the central area, to radiate cooling energy outwards, creating a positive temperature gradient from the inner to the outer rings. This facilitates the control of storage or cultivation temperatures for chicory roots, adjusting the growth cycle of the bulbs. Each ring can be independently adjusted based on market forecasts, allowing for control over the timing of bulb release according to market demand and maximizing economic benefits. Simultaneously, it enables convenient temporary storage of unsold bulbs without the need for additional cold storage or transportation, saving costs and preventing bulb rot due to substandard temperature and humidity during centralized management.

[0049] Meanwhile, to ensure a stable temperature gradient between cultivation spaces, this embodiment uses double-layered concrete fabric to construct the partition wall 1021, with polyurethane foam or other lightweight insulation materials filling the space between the two layers, thus creating temperature isolation for the cultivation space 1022. Access openings 1025 are also provided on the partition wall to facilitate user access to each cultivation space.

[0050] Furthermore, to ensure better fixation of the concrete fabric, hooks are arranged at preset intervals on the upper part of the concrete fabric so that the concrete fabric is clamped by the hooks. At the same time, through nails are arranged between the two layers of concrete fabric according to a preset area, with the through nails distributed in a triangular wave shape or a sine or cosine wave shape, so that the concrete fabric is firm and does not tilt.

[0051] like Figure 1 and Figure 2 As shown, the heat storage unit 103 is located at the top of the cultivation chamber 102 and is isolated from the cultivation chamber 102 by an air insulation layer 1033, forming a relatively sealed space in the cultivation chamber 102. Simultaneously, the air insulation layer 1033 also serves as a ventilation duct. A brine tank 1031 containing high-concentration brine is installed inside the heat storage unit 103. A high-transmittance PC sun panel 1032 covers the brine tank 1031 at the top of the heat storage unit 103. Sunlight shines through the PC sun panel into the brine tank, heating the high-concentration brine and storing the heat generated by solar radiation in the heat storage unit 103. Because the high-concentration brine has a high density and is closer to the lower layer of the tank water, even after absorbing solar heat, its density remains higher than that of the surface water, preventing vertical convection. Therefore, this high-temperature, high-concentration brine remains in the lower layer of the tank water, and can be obtained from there through valves in the control pipes when the cultivation space requires heat.

[0052] Therefore, a serpentine pipe arrangement 1026 is arranged within the cultivation space 1022, communicating with the lower layer of the pool water in the heat storage unit 103. An inlet valve (solenoid valve) is installed at the pipe inlet. By controlling the inlet valve, the high-temperature brine from the lower layer of the brine pool 1031 flows along the pipe to the cultivation space 1022, raising the temperature within the cultivation space 1022 through heat radiation and convection. Once the desired temperature is reached, the inlet valve is closed, and the water in the pipe flows into a temporary small pool, then is pumped back to the brine pool in the heat storage unit, thus continuing to collect and store heat, achieving a circulation effect.

[0053] Based on this, this embodiment uses a cold storage unit 101 and a heat storage unit 103 to regulate the temperature of the cultivation unit 102 by storing natural cold and collecting solar heat, thereby minimizing the operating cost of the cultivation system with extremely low energy consumption. Simultaneously, it utilizes spatial temperature gradients to store fleshy roots and unsold buds, and to adjust the softening cultivation cycle of each cultivation unit, thus enabling control over the market launch time of commercial buds according to market demand to achieve maximum economic benefits.

[0054] Furthermore, a lifting channel 1027 is provided within the cultivation section 102. This lifting channel 1027 can be designed as an elevator to help users enter and exit the cultivation space. An airflow channel 1029 is provided within the air insulation layer 1033, and a vent 1028 is provided at the top of each cultivation space 1022, connecting the vent 1028 to the airflow channel 1029. Simultaneously, the airflow channel 1029 is circumferentially arranged around the lifting channel and communicates with the air insulation layer 1033, exchanging gases with the outside air to control the humidity and oxygen content within the cultivation space 1022.

[0055] Example 2

[0056] The softened chicory cultivation system provided in this embodiment is suitable for northern regions where winter temperatures are below 0°C, such as... Figures 3 to 4 As shown, the main difference compared to Embodiment 1 is that the cultivation space 1022 is on the same plane, and the heating rods are arranged around the outer perimeter of the cultivation chamber. Furthermore, the heating rods are installed vertically, with their condensation section in contact with outdoor air and their evaporation section placed in the cold storage section.

[0057] By placing heat pipes around the perimeter of the cultivation space, a temperature gradient is created, with a lower temperature on the outer edge and a higher temperature on the inner edge. This temperature gradient allows for the storage of fleshy roots, temporary storage of buds, and regulation of the different softening cycles in each cultivation space. This enables the control of the market launch time of commercial buds based on market demand, thereby maximizing economic benefits.

[0058] In northern regions, where outdoor temperatures are typically below 0°C in winter, and the temperature of the soil beneath the surface is usually higher than that of the outdoor air, heat pipes can operate normally without the need for vortex tubes. This allows the temperature of the water tank in the cold storage section to gradually decrease and freeze, forming ice blocks.

[0059] Furthermore, in the cultivation section 102 of this embodiment, the lifting channel is located at the center, and an air flow channel is fixedly connected to the outer periphery of the lifting channel. The air exchange between the cultivation room and the outside is controlled by opening and closing the ventilation window at the top of the air flow channel.

[0060] Example 3

[0061] This embodiment also provides a construction process for a cultivation system, such as... Figure 5 As shown, it includes the following steps:

[0062] S1. Excavate a construction space at a preset location that can accommodate the cultivation room. The construction space is a cavity formed by the space excavated below the ground level and the space above the ground level. The earthwork of the part of the cavity above the ground level is formed by the dike formed by piling the earthwork excavated in the construction space along its circumference.

[0063] S2. In southern regions where winter temperatures remain relatively high, the cold storage unit should be located in the central area of ​​the bottom of the cultivation chamber, excavated to a sufficient depth to achieve a suitable volume and store adequate cooling capacity. A lifting channel and a surrounding airflow channel should be installed above the cold storage unit. The remaining spaces in the cultivation chamber, at the same level as the top of the cold storage unit, should be designated as the cultivation section, a fleshy root storage chamber, and a temporary bud storage chamber. In northern regions where winter temperatures drop below 0°C, the cold storage unit should be installed around the outer edge of the cultivation chamber. The bottom of the cold storage unit can be level with or slightly lower than the bottom of the rest of the cultivation chamber. A lifting channel and a surrounding airflow channel should be installed in the central area of ​​the cultivation chamber. The remaining spaces in the cultivation chamber should be designated as the cultivation section, a fleshy root storage chamber, and a temporary bud storage chamber.

[0064] S3. Use double-layer concrete cloth to construct partition walls in the cultivation section, and fill the space between the two layers of concrete cloth with polyurethane foam or other lightweight insulation materials to form a cultivation space with a U-shaped or ring-shaped structure.

[0065] S4. A cooling pool is installed below the ground level of the cultivation space. The bottom and sides of the cooling pool are waterproofed. The cooling pool is separated from the cultivation space by a floor that serves as radiant cooling.

[0066] S5. The heat pipes are arranged in the center of the cultivation room or around the outer perimeter of the cultivation room. The heat pipes are installed vertically, with their evaporation part placed in the cold storage part and their condensation part extending out of the cultivation room and in contact with the outdoor air. In the case of southern regions where the winter temperature is still high, vortex tubes are installed at the condensation parts of each heat pipe, and the cold air output end of the vortex tube blows air to the condensation parts of each heat pipe to cool them down, so that the local area near the condensation part of the heat pipe is below 0°C.

[0067] S6. A heat storage unit is set above the cultivation unit, and heat is transferred between the heat storage unit and the cultivation space through a solenoid valve and a serpentine pipe arrangement. A high-density brine pool is set inside the heat storage unit, and a high-transmittance PC sun panel is set at the top of the heat storage unit.

[0068] Therefore, by utilizing the cold storage unit's ability to store cold energy and the heat storage unit's ability to store heat energy, the system can provide cold and heat energy for temperature regulation in various functional spaces within the cultivation room anytime and anywhere. This means it is prepared to regulate temperature at any time using the stored cold and heat energy. More importantly, once this stored cold and heat energy is designed and constructed, no additional costs will be incurred during subsequent operation, thus reducing daily operating costs.

Those skilled in the art can make various modifications or additions to the described embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims. For example, the technical solutions described in this invention only require slight adjustments to the specific growth parameters of certain crops to achieve the cultivation of those crops, such as saffron and certain edible fungi.
