Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a germination device for enriching soybean isoflavones. Background Technology

[0002] Existing soybean germination equipment primarily focuses on temperature and humidity control, achieving basic germination conditions through mechanical spraying and heating modules. However, this technology lacks precise control over key parameters such as UV-B irradiation and salt stress environments, resulting in long soybean germination cycles and low efficiency in the synthesis of functional active substances (such as isoflavones). With the growing market demand for functional foods, achieving targeted synthesis of active ingredients through equipment innovation has become a technological bottleneck in the industry.

[0003] Traditional bean sprout machines typically use a constant-intensity UV light source, which cannot dynamically adjust the UV-B irradiation intensity. Experiments show that constant irradiation intensity easily induces photoinhibition effects, leading to excessive oxidation of isoflavone precursors. More seriously, existing technologies face structural contradictions in achieving multi-parameter coordinated control. To simultaneously regulate temperature, humidity, UV irradiation, and salt solution concentration, traditional solutions often employ a split-structure design (independent salt solution tank + light chamber + incubator), resulting in system response delays exceeding 5 minutes and energy consumption per unit increasing to 2.3 kW·h / kg.

[0004] Therefore, there is a need for a soybean germination device that can break through the barrier of using constant intensity ultraviolet light sources for irradiation, dynamically adjust the UV-B irradiation intensity, achieve multi-parameter synergistic control, shorten the germination cycle, increase the isoflavone content in germinated soybeans, and reduce energy consumption.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] See Figure 1This utility model provides a germination device for enriching soybean isoflavones, including a box 1 and a perforated tray 2 disposed inside the box 1. Soybeans to be germinated are placed on the perforated tray 2. An ultraviolet lamp group 3 is disposed above the perforated tray 2. The ultraviolet lamp group 3 emits ultraviolet light of at least UV-B wavelength. A lifting component is provided between the ultraviolet lamp group 3 and the box 1 and / or between the perforated tray 2 and the box 1. That is, the lifting component can be disposed only between the ultraviolet lamp group 3 and the box 1, or only between the box 1 and the perforated tray 2, or both. The lifting component is used to adjust the distance between the ultraviolet lamp group 3 and the perforated tray 2 to meet the ultraviolet light emission requirements. The invention employs various irradiation conditions to broaden its applicability. The chamber 1 is equipped with a spray assembly and a circulating air duct assembly. The spray assembly sprays salt solution into the chamber 1. An air duct control assembly connected to the circulating air duct assembly is located outside the chamber 1. This air duct control assembly regulates the temperature and humidity inside the chamber 1. The invention adopts a closed or semi-closed design and incorporates a UV lamp assembly 3 capable of emitting UV-B wavelength ultraviolet light, meeting the UV-B irradiation requirements of germinating soybeans. Furthermore, the invention achieves closed-loop control of UV intensity, salt concentration, and temperature and humidity parameters, thereby realizing multi-parameter coordinated regulation. Compared to traditional split structures, this invention effectively shortens the germination cycle and reduces energy consumption.

[0029] As an embodiment of this utility model, the hollow tray 2 adopts a multi-layer structure design and is made of corrosion-resistant material, which supports the layered isolation cultivation of soybean seeds. At the same time, the angle of the hollow tray 2 is adjustable, which is conducive to the separation of salt solution from soybeans and avoids the accumulation of salt solution on the surface of soybeans.

[0030] As one embodiment of this utility model, the ultraviolet lamp group 3 includes multiple first ultraviolet lamps and multiple second ultraviolet lamps. The multiple first ultraviolet lamps form a first ultraviolet lamp group, and the multiple second ultraviolet lamps form a second ultraviolet lamp group. The first ultraviolet lamps and / or the second ultraviolet lamps emit ultraviolet light of UV-B wavelength. The first ultraviolet lamps and the second ultraviolet lamps are independently controlled. The two groups of ultraviolet lamps can be used individually or in combination, which facilitates the adjustment of the UV-B irradiation intensity and its uniformity, meets the ultraviolet irradiation intensity requirements of different growth stages of germinated soybeans, and increases the isoflavone content in germinated soybeans. In addition, each ultraviolet lamp can be used independently. The two types of ultraviolet lamps can adopt the following three structures:

[0031] Structure 1: Both the first and second ultraviolet lamps emit ultraviolet light with UV-B wavelength;

[0032] Structure 2: The first ultraviolet lamp emits ultraviolet light of UV-B wavelength, and the second ultraviolet lamp emits ultraviolet light of other wavelengths;

[0033] Structure 3: The first ultraviolet lamp emits ultraviolet rays of other wavelengths, and the second ultraviolet lamp emits ultraviolet rays of UV-B wavelength.

[0034] When structure one is adopted, all ultraviolet lamps emit UV-B with a wavelength range of 280-320nm, which belongs to medium-wave ultraviolet radiation. By controlling the first and second ultraviolet lamps, the irradiance intensity and uniformity of UV-B can be adjusted to meet the ultraviolet irradiance intensity requirements of different growth stages of germinated soybeans and effectively increase the isoflavone content in germinated soybeans. Preferably, the ultraviolet lamp group 3 is arranged in an array, with the first and second ultraviolet lamps arranged alternately, which can improve the irradiance uniformity of soybeans on the hollow tray 2.

[0035] As one embodiment of this utility model, a lifting assembly is provided between the hollow tray 2 and the box body 1. The box body 1 is provided with a hollow guide column 41, and the hollow tray 2 is provided with a guide rod 42 that moves within the guide column 41. The lifting assembly includes a driving component disposed within the box body 1 and a telescopic rod 43 driven by the driving component. The telescopic rod 43 drives the hollow tray 2 to lift and lower. The driving component can adopt various structures, such as a motor, cylinder, hydraulic cylinder, etc., as long as the telescopic rod 43 can be extended and retracted. The guide column 41 and the guide rod 42 play a guiding role in the lifting and lowering of the hollow tray 2, avoiding the abnormal phenomenon of the hollow tray 2 tilting to one side during the lifting and lowering process, and improving the lifting stability and reliability of the hollow tray 2.

[0036] As one embodiment of this utility model, multiple guide columns 41 and guide rods 42 are provided. The multiple guide rods 42 are evenly distributed on the edge of the hollow tray 2, so that the hollow tray 2 is subjected to uniform force during the lifting process, further improving the lifting stability of the hollow tray 2. Preferably, a horizontally arranged guide plate 44 is provided between all the guide rods 42. The driving end of the telescopic rod 43 is connected to the guide plate 44, that is, the driving component drives the telescopic rod 43 to drive the guide plate 44 to lift and lower, thereby driving all the guide rods 42 to lift and lower synchronously, improving the synchronization between the guide rods 42, and further improving the lifting stability and reliability of the hollow tray 2. Similarly, multiple driving components and telescopic rods 43 can also be used. Multiple telescopic rods 43 act on the guide plate 44, which can increase the driving force of the guide plate 44 and achieve the synchronization between multiple telescopic rods 43. Moreover, when some driving components or telescopic rods 43 fail, the remaining driving components and telescopic rods 43 can still continue to work, maintaining the normal operation of the whole device, reducing equipment downtime, and improving work efficiency.

[0037] As one embodiment of this utility model, the spray assembly includes a plurality of nozzles 51 disposed on the side wall of the housing 1. The nozzles 51 are higher than the upper surface of the hollow tray 2. Preferably, the nozzles 51 are arranged in an array. A liquid storage tank 52 is provided outside the housing 1. The liquid storage tank 52 stores salt solution. A liquid supply pump 53 is provided between the nozzles 51 and the liquid storage tank 52. When it is necessary to spray salt solution into the housing, the liquid supply pump 53 draws the salt solution in the liquid storage tank 52 into the nozzles 51 and sprays it out through the nozzles 51. Preferably, the salt solution in the nozzles 51 is sprayed out in the form of mist.

[0038] As one embodiment of this utility model, an electromagnetic valve is provided between the nozzle 51 and the storage tank 52. The dynamic switching of different salt stress stages is realized by controlling the opening and closing of the electromagnetic valve. The electromagnetic valve and the nozzle 51 can adopt various correspondences, such as one electromagnetic valve controlling one nozzle 51, or one electromagnetic valve controlling a group of nozzles 51, and a group of nozzles 51 includes at least two nozzles 51.

[0039] As one embodiment of this utility model, the housing 1 is provided with a perforated plate 54, which divides the housing 1 into an upper chamber 11 and a lower chamber 12. The nozzle 51 and the perforated tray 2 are both located in the upper chamber 11. The bottom of the lower chamber 12 is provided with a drain outlet. A return pipe 55 is provided between the drain outlet and the storage tank 52. The nozzle 51 sprays the brine into the upper chamber 11. Then the brine passes through the perforated plate 54 into the lower chamber 12 and accumulates. Finally, it is discharged from the drain outlet and enters the storage tank 52, thereby realizing the recycling of the brine. Preferably, the return pipe 55 is provided with a one-way valve and a filter 56. The one-way valve realizes the one-way circulation of the brine from the lower chamber 12 to the storage tank 52. The filter 56 can filter the brine in the return pipe 55 to prevent impurities from entering the storage tank 52 with the brine, ensuring the cleanliness of the brine in the storage tank 52 and ensuring the safety and reliability of the entire circulation process.

[0040] As one embodiment of this utility model, the lower chamber 12 is provided with an inclined liquid guide plate 57. The lower end of the liquid guide plate 57 is adjacent to the drain outlet. The brine entering the lower chamber 12 flows to the drain outlet through the guiding action of the liquid guide plate 57, avoiding the accumulation of brine at the bottom of the lower chamber 12, realizing rapid drainage and improving the circulation efficiency of brine.

[0044] Mode 3: Dehumidification mode.

Then it is heated by the heating module 71, so that the gas is in an unsaturated state and the temperature rises back to the temperature inside the chamber 1. Finally, it returns to the chamber 1, reducing the overall humidity inside the chamber 1 while keeping the temperature inside the chamber 1 constant.
