Description

Technical Field

[0001] The invention relates to the technical field of grain germination, and in particular to a grain germination method and germination equipment. Background Art

[0002] Germination equipment is a device that can promote the germination of crops such as cereals, which can provide suitable humidity and temperature for crops such as cereals to achieve the effect of promoting germination. Generally, the germination cycle of crops such as cereals is relatively long. Taking the germination of dry brown rice as an example, it usually takes more than ten or even twenty hours for the embryo to germinate after absorbing water and swelling. Therefore, for household germination equipment, usually one device can only complete the germination process once a day, for example, it takes one night to make enough germinated brown rice for one day. When more germinated brown rice needs to be prepared, the household germination equipment is insufficient. Household germination equipment usually uses a filter-shaped rice plate to carry the germinated brown rice, and keeps the germinated brown rice moist by atomized water vapor or spraying liquid. Although the amount of germination can be increased by increasing the capacity of the rice plate, when the amount of germination is large, the atomization or spraying humidification method used by traditional household germination equipment is often difficult to penetrate the brown rice to be germinated, resulting in a less than ideal germination effect.

[0003] In view of this, it is necessary to propose a new technical solution to overcome the shortcomings of the existing technology. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a grain germination method and a germination device, which are suitable for increasing the amount that can be germinated at one time and can ensure a better infiltration effect.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a method for germinating grains, comprising a first step of promoting germination of grains, wherein the first step comprises:

[0008] Wherein, the containing container has a normally open drain port which is kept open, and the normally open drain port is configured as follows:

[0009] In the soaking stage, the water injection flow rate to the containing container is greater than the drainage flow rate of the normally open drain outlet to form the accumulated water; in the germination stage, the accumulated water is discharged through the normally open drain outlet.

[0010] Optionally, during the soaking stage, water is continuously injected into the containing container, and the flow rate of the injected water is not less than the flow rate of water discharged from the normally open drain port.

[0011] Optionally, the grain germination method further comprises a second step of reducing the temperature of the grains during the germination stage, the second step comprising:

[0012] Accumulated water is formed in the containing container to soak the grains in the containing container, and the accumulated water is discharged after soaking for a set time.

[0013] Optionally, the second step is triggered by the following conditions:

[0014] (i) detecting that the temperature of the grain meets a predetermined temperature condition; and / or,

[0015] (ii) The duration of the germination phase meets the preset time conditions.

[0016] Optionally, the cereal germination method further comprises a third step of removing germination odor, the third step comprising:

[0017] forming a reservoir of water in the container to soak the grains in the container, and draining the reservoir of water after soaking for a set period of time; or,

[0018] The grains are rinsed and cleaned by injecting water into the container at a flow rate not greater than the drainage flow rate.

[0019] Optionally, in the process of forming the accumulated water, the water discharged from the storage container enters the circulation water tank, and the water in the circulation water tank is circulated and provided to the storage container.

[0020] Optionally, the water in the circulating water tank is replaced with clean water after the first step and before the second step, and / or after the second step and before the third step.

[0021] The present invention also adopts the following technical solution: a grain germination device, comprising a container for containing materials to be germinated, and a liquid supply device for injecting water into the container;

[0022] The holding container is configured to: form accumulated water so that the material to be germinated is soaked in the holding container, and to discharge the accumulated water so that the moistened material to be germinated germinates in the holding container;

[0023] Wherein, the containing container has a normally open drain port which is kept open;

[0024] Wherein, the liquid supply device is configured so that the flow rate of water injected into the containing container is greater than the flow rate of water discharged from the normally open drain port, so that accumulated water is formed in the containing container.

[0025] Optionally, the containing container comprises an outer barrel and an inner barrel disposed in the outer barrel, the outer barrel is configured to be able to accumulate liquid, and the inner barrel is configured to allow liquid to flow but restrict the passage of the material to be germinated.

[0026] Optionally, the inner barrel includes an inner barrel bottom wall configured as a filter, and the outer barrel includes an outer barrel bottom wall, and the inner barrel bottom wall and the outer barrel bottom wall are spaced apart to form a drainage space therebetween; wherein the normally open drain outlet is provided on the outer barrel bottom wall, or on a portion of the outer barrel side wall that forms a peripheral wall of the drainage space.

The holding container can be placed in and taken out of the body relatively freely without considering the alignment problem with the body. This greatly facilitates the movement and placement of the holding container after filling the heavier holding container with the material to be germinated;

[0030] 3. By injecting water while flowing out, the material to be germinated is immersed in the flowing liquid, which can make the immersion more complete and the heat transfer more uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0046] See also Figures 1 to 7As shown, the present invention provides a method for germinating grains and a grain germination device 100, and in particular, relates to a commercial or industrial germination method and device. Compared with household germination equipment, the commercial or industrial grain germination equipment 100 can germinate a larger amount at one time. The amount of grain that can be germinated at one time by household germination equipment can usually meet the needs of a family for one day, for example, it can meet the amount of three meals for 5 people at most; while the amount of grain that can be germinated at one time by commercial or industrial grain germination equipment 100 can meet the needs of communities, streets or even a larger range, and the germinated products can be sold to achieve commercial purposes. Taking brown rice germination as an example, the amount of grain that can be germinated at one time by household germination equipment is, for example, about 1-2 liters, while the amount of grain that can be germinated at one time by commercial or industrial grain germination equipment 100 is, for example, more than 5 liters, more than 10 liters, or even more than 20 liters. Of course, the present application does not specifically limit the amount of grain that can be germinated at one time by the grain germination equipment 100, and the above description only introduces the application scenario of the grain germination equipment 100. The germination method described in this application can also be used for small amounts of sprouted products such as home germination equipment.

[0047] See also Figures 1 to 3 As shown, in this embodiment, the grain germination device 100 includes a body 1 and a door 2, the body 1 and the door 2 enclose a chamber 101, and the container 3 is filled with materials to be germinated and placed in the chamber 101 for germination. The grain germination device 100 can realize water injection and immersion, drainage of the materials to be germinated placed in the chamber 101, and in some embodiments, it can realize water temperature control, environmental temperature control in the chamber 101, etc., and in some embodiments, it can realize operations such as automatic addition of materials to be germinated and stirring of the materials to be germinated.

[0048] See also Figures 4 to 7 As shown, the holding container 3 includes an outer barrel 31 and an inner barrel 32 disposed in the outer barrel 31, the outer barrel 31 is configured to contain liquid, and the inner barrel 32 is configured to allow liquid to flow but restrict the passage of the material to be germinated. In this embodiment, the outer barrel 31 is used as a container capable of storing water, and the inner barrel 32 is used as a water filtering container capable of containing the material to be germinated, and the cooperation of the two can facilitate the immersion of the material to be germinated and the discharge of the liquid; in some other embodiments, the holding container 3 is only set as an outer barrel 31, which can also achieve immersion and discharge, but compared with the above preferred inner and outer two barrels solution, its drainage is inconvenient.

[0049] See also Figure 5As shown, the outer barrel 31 includes an outer barrel side wall 311 and an outer barrel bottom wall 312, and the outer barrel side wall 311 is also provided with a handle for conveniently lifting the outer barrel 31. A drain outlet 3120 is provided on the outer barrel bottom wall 312. In the present embodiment, the drain outlet 3120 is a normally open drain outlet that remains open. In other words, the drain outlet 3120 is not provided with a valve structure that can be closed. Of course, in other embodiments, the drain outlet 3120 may be provided with a valve structure for closing the drain outlet 3120. As for how the drain outlet 3120 in the present embodiment is kept open to store water for soaking the material to be germinated, it will be described in detail later. Please refer to Figure 3 and Figure 4 As shown, the grain germination device 100 includes a support for supporting the holding container 3, and the support is provided with a plurality of pointed convex support parts 11 to prevent the drainage port 3120 from being blocked. The pointed convex support parts 11 are in contact with the outer barrel 31 of the holding container 3, so that the drainage port 3120 can be prevented from being blocked by the support and affecting drainage. In this embodiment, the support includes a plurality of triangular prism-shaped support ribs, which are in a plurality of line contacts with the bottom surface of the outer barrel 31, and will not block the drainage port 3120.

[0050] See also Figure 6 and Figure 7 As shown, the inner barrel 32 includes an inner barrel side wall 321 and an inner barrel bottom wall 322. At least the inner barrel bottom wall 322 is configured as a filter, so that the liquid flows through and the material to be germinated remains in the inner barrel 32. In this embodiment, the inner barrel side wall 321 is also configured as a filter, which can speed up the flow of liquid. The inner barrel bottom wall 322 is also provided with a support foot 3221, and when the inner barrel 32 is placed in the outer barrel 31, the support foot 3221 is supported on the outer barrel bottom wall 312. The support foot 3221 can be assembled on the inner barrel 32 by welding or by connecting means such as screws and buckles, which can realize supporting the inner barrel 32 compared to the outer barrel 31, so that the inner barrel bottom wall 322 and the outer barrel bottom wall 312 have a spacing. As a modified embodiment, the support foot 3221 can also be set on the inner surface of the outer barrel bottom wall 312 of the outer barrel 31, or be set near the lower part of the outer barrel side wall 311 of the outer barrel 31 and extend into the outer barrel 31.

[0051] Please refer again Figure 4 As shown in FIG. 1 , after the inner barrel 32 is placed in the outer barrel 31, the upper edge of the inner barrel sidewall 321 is higher than the upper edge of the outer barrel sidewall 311. In this way, when the liquid in the container 3 is poured to exceed the upper edge of the outer barrel sidewall 311 and overflows, as shown in FIG. Figure 4As shown by the dotted arrows in the partially enlarged portion, the grains to be germinated floating on the upper edge of the inner barrel side wall 321 can still be blocked by the inner barrel side wall 321 and retained in the inner barrel 32, and will not flow out with the overflow of the liquid.

[0052] Please continue reading Figure 4 As shown, there is a gap between the inner barrel sidewall 321 and the outer barrel sidewall 311, so as to form a surrounding flow cavity 301 between the two to promote the flow of liquid. That is, the diameter of the inner barrel sidewall 321 is smaller than the diameter of the outer barrel sidewall 311, so that when the inner barrel 32 is placed in the outer barrel 31, the inner barrel sidewall 321 is not in close contact with the outer barrel sidewall 311, and a surrounding flow cavity 301 surrounding the inner barrel 32 is formed between the two. The surrounding flow cavity 301 can quickly distribute the liquid to the surrounding of the inner barrel 32, reduce the flow resistance, speed up the flow of liquid, and make the infiltration of the germinated material in the inner barrel 32 more uniform.

[0053] Please continue reading Figure 4 As shown, the inner barrel bottom wall 322 of the inner barrel 32 is configured as a filter, and there is a gap between the inner barrel bottom wall 312 with the outer barrel bottom wall 312 having the drain port 3120, so as to form a drainage space 302 therebetween. The drainage space 302 is formed by supporting the outer barrel bottom wall 312 with the support legs 3221. The arrangement of the drainage space 302 can, on the one hand, prevent the inner barrel bottom wall 322 from directly contacting the outer barrel bottom wall 312, which may result in the drain port 3120 being blocked due to the close proximity of the inner barrel bottom wall 322 and the outer barrel bottom wall 312, and the water flow speed is too slow during drainage, or even the drain port 3120 is blocked and cannot be drained; on the other hand, it can prevent the inner barrel bottom wall 322 from directly contacting the outer barrel bottom wall 312, so that after drainage is completed, some liquid remains in the narrow space between the inner barrel bottom wall 322 and the outer barrel bottom wall 312 due to the surface tension of the liquid, resulting in the poor ventilation at the bottom, which may cause the germinated material at that location to rot and deteriorate easily. In this embodiment, the drain outlet 3120 is opened on the outer barrel bottom wall 312; in other embodiments, the drain outlet 3120 can also be opened on the portion of the outer barrel side wall 311 located below the inner barrel bottom wall 322, that is, the portion of the outer barrel side wall 311 forming the peripheral wall of the drainage space 302. In this way, the drain outlet 3120 can be prevented from being blocked and some impurities can be deposited on the outer barrel bottom wall 312, thereby playing a certain filtering role.

[0054] See also Figure 4As shown, in this embodiment, the holding container 3 has a drain port 3120 that remains open, and the liquid supply device 5 is configured so that the flow rate of the liquid provided to the holding container 3 is greater than the flow rate of the liquid discharged from the drain port 3120, so that the holding container 3 accumulates liquid. By so configuring, there is no need to set a valve structure that matches the drain port 3120 of the holding container 3 in the body 1, so that the holding container 3 can be relatively freely placed in the body 1 and taken out from the body 1 without considering the alignment problem with the body 1, which greatly facilitates the moving and placing of the holding container 3 after the heavy holding container 3 is filled with the germinated material. Moreover, by injecting and flowing out at the same time, the germinated material is immersed in the flowing liquid, which can make the immersion more complete and the heat transfer more uniform. In this embodiment, the grain germination device 100 also includes a circulating water tank 4, and the liquid discharged from the holding container 3 enters the circulating water tank 4 and is circulated to the holding container 3 by the liquid supply device 5. The waste of liquid resources can be reduced by liquid circulation; of course, after one or several soakings, the liquid needs to be discharged from the circulating water tank 4 and refilled with fresh liquid, such as clean water, for the next soaking. The circulating water tank 4 includes a heating device 41, which is used to heat the water in the circulating water tank 4 to maintain it at a set water temperature. Soaking the material to be germinated with water at a set water temperature can maintain the material to be germinated near a temperature suitable for germination to accelerate the germination process. In this embodiment, the heating device 41 is a heating pipe. In this embodiment, the circulating water tank 4 is arranged in the body 1, below the container 3. Since the chamber 101 surrounded by the body 1 and the door 2 is a relatively sealed chamber after the machine door 2 is closed, the liquid with a set water temperature in the circulating water tank 4 can also maintain the temperature environment of the entire chamber 101 within a temperature range suitable for germination.

[0055] The present invention also provides a grain germination method, which can be performed by the grain germination device 100 as described above.

[0056] The grain germination method comprises a first step of causing the grains to germinate, the first step comprising:

[0057] Soaking stage: forming accumulated water in the container 3 to soak the grains in the container 3; and

[0058] Germination stage: draining the accumulated water in the container 3 to allow the grains to germinate in the container 3;

[0059] The container 3 has a normally open drain port which is kept open, and the normally open drain port is configured as follows:

[0060] In the soaking stage, the water injection flow rate of the containing container 3 is greater than the drainage flow rate of the normally open drain outlet to form the accumulated water; in the germination stage, the accumulated water is discharged through the normally open drain outlet.

[0061] The grain germination method provided by the present application adopts an immersion method to soak the material to be germinated, and has a good soaking effect on the material to be germinated; and the immersion and germination are carried out in the same container, and the liquid can be discharged after the immersion is completed to germinate, which is convenient to operate and easy to implement. Moreover, the container 3 adopts a drain port 3120 that remains open, and the water storage immersion and drainage are achieved by controlling the water injection flow rate, so that there is no need to set a valve structure that matches the drain port 3120 of the container 3 in the body 1 of the equipment, so that the container 3 can be placed in the body 1 and taken out from the body 1 relatively freely without considering the alignment problem with the body 1. This greatly facilitates the moving and placing of the container 3 for the heavier container 3 after filling the material to be germinated. In addition, by injecting and flowing out at the same time, the material to be germinated is immersed in the flowing liquid, which can make the immersion more sufficient and the heat transfer more uniform.

[0062] Furthermore, in the soaking stage, the state of the submerged grains is maintained for a preset time; wherein, during the preset time, water is continuously injected into the holding container 3, and the flow rate of the injected water is not less than the flow rate of the water discharged from the drain port 3120. That is, the submerged state is maintained by continuously injecting water; in this process, the injection flow rate can be equal to or greater than the drainage flow rate. When the injection flow rate is equal to the drainage flow rate, the total amount of water in the holding container 3 maintains a dynamic balance, and when the injection flow rate is greater than the drainage flow rate, the excess water in the holding container 3 will overflow from the mouth of the holding container 3. In some embodiments, the preset time is 0.5h to 2h. In the germination stage, the flow rate of the injected water into the holding container 3 is less than the flow rate of the water discharged from the drain port 3120. In this embodiment, the injection of water into the holding container 3 is stopped, that is, the injection flow rate is 0; of course, in other embodiments, water can also be injected into the holding container 3 to ensure that the injection flow rate is less than the drainage flow rate to achieve drainage.

[0063] The grain germination method further comprises a second step of lowering the temperature of the grains in the germination stage, wherein the second step comprises: forming accumulated water in the container to soak the grains in the container, and draining the accumulated water after soaking for a set time. The second step can make the temperature of the wet grains in the germination process uniform.

[0064] Specifically, the grain germination device 100 includes a liquid supply device 5 for supplying liquid to the holding container 3. The liquid supply device 5 is configured to: during the process of soaking the moistened material to be germinated for germination, supply liquid to the holding container 3 so that the holding container 3 accumulates liquid again to soak the material to be germinated, thereby dispersing the heat generated by the material to be germinated during the germination process by the liquid, so that the temperature of each part of the material to be germinated is balanced.

[0065] In the case of germinating a large amount of materials at one time, one of the main difficulties faced by technicians is the difficulty in ensuring uniform temperature and humidity in various parts of the materials to be germinated. The traditional method of spraying or atomizing humidification makes it difficult to penetrate the middle part of the materials to be germinated, and during the germination process, the heat generated in the middle part of the materials to be germinated is difficult to dissipate, which may cause heartburn and rot, resulting in less than ideal germination effect. In order to improve the above situation, the prior art usually changes the carrying method of the materials to be germinated so that the materials to be germinated are as thin as possible, for example, multiple carrying frames are often used to disperse the materials to be germinated; or improve the penetration of the spray device or the atomizing humidification device, such as using high-pressure water, fan-driven atomization or structural improvements to the spray or atomizing humidification device. The above-mentioned prior arts have the problems of complex structure, cumbersome operation, increased cost, etc., and the improvement effect of the problem that the temperature and humidity of various parts of the materials to be germinated are difficult to ensure is also relatively limited.

[0066] The present invention soaks the material to be germinated in an immersion manner, and has a better soaking effect on the material to be germinated; and the immersion and germination are carried out in the same container 3, and the liquid can be discharged after the immersion is completed to carry out the germination, which is convenient to operate and easy to implement; in the germination process, in order to prevent the heat generated by the material to be germinated during the germination process from being unable to be dissipated, especially when the amount of the material to be germinated is large, the heat in the center is difficult to dissipate, which may cause heartburn and rot, the material to be germinated is soaked again during the germination process, so that the heat generated by the material to be germinated during the germination process is dispersed by liquid, so that the temperature of each part of the material to be germinated is balanced, so that a large amount of material to be germinated can also achieve a better germination effect.

[0067] Furthermore, the second step is triggered by the following conditions: (i) the temperature of the grains is detected to meet the preset temperature condition; and / or, (ii) the duration of the germination stage meets the preset time condition. The second step is also the soaking and heat-averaging step, and its purpose is to make the temperature of the material to be germinated uniform, especially to cool down the high temperature inside the germinated grains. In some embodiments, the soaking and heat-averaging step is triggered by detecting the temperature of the grains, which can be specifically detected when the temperature of a certain detection point is higher than the preset temperature, or when the temperature difference of the grains between two detection points is greater than the preset temperature difference, or other conditions based on the detected temperature. In other embodiments, the soaking and heat-averaging step can be triggered according to the duration, which can be triggered every 3 hours or so; in other embodiments, it can also be a combination of temperature conditions and time conditions, such as being triggered when the temperature condition is met, and being triggered by the time condition when the temperature condition is not met.

[0068] The grain germination method further includes a third step of removing the odor of germination, and the third step includes: forming accumulated water in the holding container to soak the grains in the holding container, and discharging the accumulated water after soaking for a set time; or, flushing and cleaning the grains in the holding container with a water injection flow rate not greater than the drainage flow rate. The third step is also a cleaning and deodorization step. There are two ways to clean and deodorize, one is still to clean by immersion and drainage, and the other is to flush, and no water is accumulated to immerse the grains during the flushing process. The odor generated by germination can be reduced by the cleaning and deodorization step. Furthermore, the method further includes adding ozone, wherein the ozone is added to the water used to soak the grains, or is passed into the holding container 3, or is passed into the chamber 101 where the holding container 3 is located. The ozone can be passed in the germination process to participate in the germination process through ozone, play a purification role, and increase the oxygen content in the water to promote the germination process; the ozone can also be passed in the cleaning and deodorization process after the germination is completed, so as to improve the deodorization effect through ozone.

[0069] Furthermore, the water in the circulating water tank 4 is replaced with clean water after the first step and before the second step, and / or after the second step and before the third step. Since the water use in the three steps is relatively long, there is a risk of microbial growth in the water used last time within a relatively long time interval. Therefore, before the water use in the above three steps, the water in the circulating water tank 4 is replaced with clean water to reduce impurity residues and microbial growth. In a continuous circulation soaking process, such as the soaking water absorption and soaking heat soaking processes, the discharged water enters the circulating water tank 4 and is circulated and transported to the holding container 3 to reduce water consumption and avoid water resource waste.

[0070] When using the grain germination device 100 provided by the present invention, first, add the material to be germinated into the containing container 3 outside the machine body 1, and put the containing container 3 containing the material to be germinated into the chamber 101 of the machine body 1; secondly, close the machine door 2, start the grain germination device 100, and inject water into the containing container 3 by the liquid supply device 5. The water flows out while being injected. However, since the amount of water injected is greater than the amount of water discharged, the liquid in the containing container 3 is filled after a period of time. At this time, the water injection flow rate can be maintained or reduced to the same as the outflow flow rate, so that the containing container 3 remains in a filled state for a period of time until the grain to be germinated is ready. The sprout material absorbs enough water and expands; then stop injecting water, and the liquid in the container 3 gradually flows out. After the liquid flows out, the soaked material to be sprouted is germinated in the container 3; during the germination process, the above-mentioned water injection and drainage process can be repeated once or multiple times. This process is to make the temperature of the grains in the germination process balanced by soaking, avoid heartburn and keep the temperature of the grains in various places at a suitable germination temperature; finally, after the germination is completed, use clean water to spray or soak the sprouted material to remove odor; the germination process is completed in this way, open the machine door 2, and take out the container 3.

[0071] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
