Description

Technical Field

[0001] The present invention relates to the field of whole grain processing, in particular to a pre-cooking device for sprouted whole grains, sprouting equipment and a processing method thereof. Background Art

[0002] In the prior art, whole grains refer to grains that have not undergone fine processing, or that, despite milling, crushing, or flaking, retain the endosperm, germ, bran, and natural nutrients characteristic of the entire grain. In other words, whole grains primarily consist of the endosperm, germ, and bran. Consuming whole grains can significantly reduce the incidence of chronic diseases and has become an indispensable food source in the Chinese diet. However, due to the presence of the bran and germ, whole grains are difficult to cook, have a rough texture, and have a short shelf life. Addressing these three major industry issues and achieving automated production is key to the development of the whole grain industry. Because whole grains are hulled, they are more susceptible to microbial growth and odor generation under suitable germination temperature, humidity, and oxygen conditions. Therefore, antibacterial measures are crucial during the germination process. Traditional seed germination equipment lacks effective antibacterial measures and often relies on manual loading and unloading, making it difficult to maintain stable and constant temperature and humidity. Furthermore, prior art methods for germinating whole grains typically require a certain degree of dehydration after germination before sealing. However, this not only increases energy consumption but also makes the dehydrated whole grains difficult to cook and have a rough texture.

[0003] Patents CN103844206A, CN101984852A, and CN105124433A compound / process dried germinated brown rice and dry the rice to produce dehydrated rice. However, the rice grains are easily damaged during the drying process, resulting in significant loss of nutrients and poor edible quality after rehydration. Patent document CN109619421A discloses an industrialized method for producing ready-to-eat germinated brown rice. This method involves first treating the rice to obtain crude ready-to-eat germinated brown rice, then air-selecting the rice to remove debris, resulting in clean, non-sticky, uniformly sized semi-finished ready-to-eat germinated brown rice granules. Finally, the rice is subjected to high-temperature roasting and puffing to obtain the finished product, which resembles traditional rice. This double roasting process not only sterilizes bacteria and enzymes but also ensures that the rice is thoroughly cooked, resulting in a more fragrant finished product. However, it inevitably limits the eating habits of germinated brown rice, which can only be puffed and cannot be steamed or boiled. Summary of the Invention

[0004] The purpose of the present invention is to provide a pre-cooking device for sprouted whole grains, a sprouting device and a processing method thereof, so as to solve the problems existing in the above-mentioned prior art.

[0012] Preferably, the water supply mechanism includes a disc spray pipe for spraying the whole grains in the germination tank and a water collecting pipe for collecting the warm water after spraying. The disc spray pipe and the water collecting pipe are connected, and the disc spray pipe is connected to a pumping mechanism for transporting the collected warm water to the disc spray pipe for spraying.

[0013] Preferably, the germination tank is provided with a stirring mechanism for stirring the whole grains during spraying.

[0014] Preferably, the warm water tank is connected to an ozone generator for regularly introducing ozone into the warm water inside the tank.

[0015] Preferably, the germination tank is connected to a cleaning mechanism for introducing water into the whole grains inside the germination tank before germination, and an overflow port for floating and overflowing impurities is opened on the tank body of the germination tank, and the overflow port is located above the whole grain pile.

[0016] A whole grain processing method is also provided, comprising the following steps:

[0017] Loading: Transfer the whole grains to the sprouting tank;

[0018] Cleaning and soaking: Pour cleaning water into the germination tank, start stirring after the liquid level of the cleaning water is above the whole grains, continue to pour cleaning water, and when the liquid level reaches the overflow port, continue to pour cold water for 3-5 minutes to clean the whole grains, drain the cleaning water, and pour warm water from the warm water tank into the germination tank until the whole grains are covered. After soaking for 2-4 hours, drain the warm water;

[0019] Germination: Soak the whole grains in warm water, drain it, refill it with warm water, start the spray cycle, and stir the whole grains. After 3-5 minutes of spraying, drain the warm water, refill it with warm water after 2 hours, start spraying and stirring, and repeat the cycle until the germination is completed;

[0020] Discharging and draining: the sprouting tank discharges the sprouted whole grains, and inputs the sprouted whole grains into the vibrating screen, vibrates and drains the sprouted whole grains, and evenly inputs the sprouted whole grains into the lifting mechanism to drain the moisture on the surface of the sprouted whole grains;

[0021] Packaging, pre-cooking and sterilization: The sprouted whole grains after the surface water is drained are lifted to the packaging machine hopper for quantitative packaging. The packaged sprouted whole grains are transferred to the high-pressure sterilization mechanism for pre-cooking and sterilization.

[0022] Preferably, in the germination step, ozone is introduced into the warm water tank for 20-30 minutes every 6 hours.

[0023] Compared with the prior art, the present invention has achieved the following technical effects:

[0024] First, a drainage mechanism, a packaging mechanism and a high-temperature and high-pressure sterilization mechanism are sequentially arranged along the direction of the processing process of the sprouted whole grains. The drainage mechanism is used to drain the surface moisture of the sprouted whole grains before packaging. The packaging mechanism is used to pack the drained sprouted whole grains into a number of packaging bags. The high-temperature and high-pressure sterilization mechanism is used to perform a high-temperature and high-pressure pre-cooking treatment and sterilization treatment on the sprouted whole grains packaged in the packaging bags. After the surface moisture of the sprouted grains is drained, they are packaged in a number of packaging bags, and then the sprouted whole grains packaged in the packaging bags are pre-cooked and sterilized at a high temperature and high pressure. On the one hand, in the sealed package, the moisture is locked, and the water molecules move violently at high temperature, the cortical fibers become loose, and the internal starch is fully gelatinized. When steamed as a staple food, the taste is softer and the cooking performance is better. On the other hand, all the microorganisms in the packaging bags are killed by the action of high temperature and high pressure, which effectively extends the shelf life of the sprouted whole grains.

[0025] Second, a lifting mechanism for conveying sprouted whole grains is provided between the packaging mechanism and the vibrating screen. The conveying portion of the lifting mechanism is in a gradually rising inclined structure along the conveying direction. When the sprouted whole grains are conveyed from the vibrating screen to the packaging mechanism, the moisture gradually slides downward due to the gradual rise of the whole structure, and the moisture not removed by the vibrating screen slides away from the sprouted whole grains from top to bottom as much as possible.

[0026] Third, the water supply mechanism includes a disc spray pipe for spraying the whole grains in the germination tank and a water collecting pipe for collecting the warm water after spraying. The disc spray pipe and the water collecting pipe are connected, and the disc spray pipe is connected to a pumping mechanism for transporting the collected warm water to the disc spray pipe for spraying. Through the self-circulation generated between the disc spray pipe and the water collecting pipe, the warm water can continuously spray the whole grains, ensuring that the whole grains can be fully heated and improving their own germination uniformity and effect.

[0027] Fourth, the germination tank is equipped with a stirring mechanism for stirring the whole grains during spraying, so that the sprayed warm water can fully soak the whole grains, ensuring that the whole grain pile in the germination tank can be evenly in the germination environment, ensuring the uniformity of the whole grain germination.

[0028] Fifth, the germination tank is connected to an ozone generator that is used to inject ozone into the warm water inside it at equal time intervals. Whole grains are more likely to breed microorganisms and produce odor under germination conditions because they have removed their shells. Regularly injecting ozone can effectively inhibit bacteria and reduce odor.

[0029] Sixth, the germination tank is connected to a cleaning mechanism for introducing water into the whole grains inside the germination tank before germination, and an overflow port is provided on the tank body of the germination tank for floating up and overflowing impurities. The overflow port is located above the whole grain pile. Therefore, before germination, water is injected into the germination tank so that the floating impurities mixed in the whole grains can float up under the action of the water flow and flow out of the germination tank through the overflow port, thereby ensuring the cleanliness of the whole grains.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The purpose of the present invention is to provide a pre-cooking device for sprouted whole grains, a sprouting device and a processing method thereof, so as to solve the problems existing in the above-mentioned prior art. After the surface moisture of the sprouted grains is drained, they are divided into several packaging bags, and then the sprouted whole grains packaged in the packaging bags are subjected to high-temperature and high-pressure pre-cooking treatment and sterilization treatment. On the one hand, in the sealed package, the moisture is locked, and the water molecules move violently at high temperature, the cortical fibers become loose, and the internal starch is fully gelatinized. When steamed as a staple food, the taste is softer and the steaming performance is better. On the other hand, all the microorganisms in the packaging bags are killed by the action of high temperature and high pressure, which effectively extends the shelf life of the sprouted whole grains.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 3 As shown, a pre-cooking device for sprouted whole grains is provided, wherein the sprouted whole grains are products consisting of young sprouts and endosperm with cortex obtained by sprouting whole grains to a certain extent under certain temperature, humidity and oxygen conditions, and the whole device includes a draining mechanism, a packaging mechanism 13 and a high-temperature and high-pressure sterilization mechanism arranged in sequence along the direction of the processing process of the sprouted whole grains; the draining mechanism is used to drain the surface moisture of the sprouted whole grains before packaging, and preferably it adopts a filter screen or a filter plate and other structures; the packaging mechanism 13 is used to pack the sprouted whole grains after draining the moisture into a number of packaging bags, and preferably it is provided with a packaging machine hopper to quantitatively package the sprouted whole grains, preferably each bag contains 50 to 100g of sprouted whole grains, and an exhaust device is provided to exhaust the sprouted whole grains and package them to form a vacuum packaging environment, and the whole packaging mechanism 13; the high-temperature and high-pressure sterilization mechanism is used to package the sprouted whole grains packaged in the packaging bags The high-temperature and high-pressure pre-cooking and sterilization treatments are carried out, and preferably a high-pressure sterilizer is used. After the high-pressure sterilizer is opened, the packaging bag storing the sprouted whole grains is transported to the interior thereof by the packaging mechanism 13, and then the high-pressure sterilizer is sealed to generate a high-temperature and high-pressure internal environment, preferably the internal temperature is 115°C, the internal air pressure is 0.20MPa, and the packaging belt is continuously acted on for 20 to 25 minutes. After the surface moisture of the sprouted grains is drained off by the entire device, the grains are divided into several packaging bags, and then the sprouted whole grains packaged in the packaging bags are pre-cooked and sterilized at high temperature and high pressure. On the one hand, in the sealed package, the moisture is locked, and the water molecules move violently at high temperature, the cortical fibers become loose, and the internal starch is fully gelatinized. When steamed as a staple food, the taste is softer and the cooking performance is better. On the other hand, all the microorganisms in the packaging bag are killed by the action of high temperature and high pressure, which effectively extends the shelf life of the sprouted whole grains.

[0039] Furthermore, the drainage mechanism includes a vibrating screen 9 for vibrating and draining the germinated whole grains. Since the germinated whole grains require warm water during processing, they are transported out of the germination tank 3 after the germination process is completed with a large amount of moisture. The moisture on the surface of the germinated whole grains is fully vibrated away from the germinated whole grains through the vibrating screen 9 to ensure the dryness of the germinated whole grains. The discharge end of the vibrating screen 9 is connected to the packaging mechanism 13 to transport the germinated whole grains to the packaging mechanism 13.

[0040] Among them, a lifting mechanism for conveying germinated whole grains is provided between the packaging mechanism 13 and the vibrating screen 9, and a scraper elevator 11 is preferably used. The scraper elevator 11 lifts the drained material to the packaging machine hopper for quantitative packaging. A partition is provided at the outlet of the vibrating screen 9 so that the germinated whole grains enter the scraper elevator 11 evenly. The conveying part of the lifting mechanism is a gradually rising inclined structure along the conveying direction. When the germinated whole grains are conveyed from the vibrating screen 9 to the packaging mechanism 13, due to its overall gradual rise, the moisture gradually slides downward, and the moisture not removed by the vibrating screen 9 slides away from the germinated whole grains from top to bottom as much as possible; preferably, an air supply mechanism for air-drying the conveyed whole grains is provided on one side of the conveying part, so that the surface of the germinated whole grains can be dried during transportation, or an air-blown drainage conveyor 12 is provided between the scraper elevator 11 and the packaging mechanism 13 for drainage, and the air-blown drainage conveyor 12 adopts a cold fan to avoid affecting the degree of germination.

[0041] Specifically, in the prior art, the dehydration treatment of the sprouted whole grains for sealing cannot guarantee the taste of the sprouted whole grains, and inevitably causes energy consumption. In another prior art, the whole grains are steamed after vacuum packaging, but a large amount of water still needs to be added during vacuum packaging to ensure the steaming effect. However, after adding water, the sprouted whole grains will inevitably become too soft and rotten under the action of excessive water, which is not conducive to the subsequent different treatment methods of the sprouted whole grains when used as a staple food. In this application, the water on the surface of the sprouted whole grains is fully drained, and only the water absorbed by the interior is sufficient. Then, under high temperature, the water molecules move violently, the cortical fibers become loose, and the internal starch is fully gelatinized, which can not only ensure the softness of the sprouted whole grains to a certain extent, but also ensure the subsequent different eating methods of the sprouted whole grains.

[0042] A whole grain germination device is also provided, comprising a germination device and a pre-cooking device for germinating whole grains located on the output side of the germination device. The germination device comprises a germination tank 3 and a warm water tank 2 storing warm water required for whole grain germination. The warm water tank 2 is provided with a water delivery mechanism for inputting warm water into the germination tank 3 at equal time intervals. Preferably, the warm water tank 2 is a sandwich insulation tank, which is electrically heated to a set temperature of 30 to 35°C and maintained at a constant temperature. When the liquid level is lower than the maximum water level, water is automatically replenished and heated to the set temperature, and the operation is repeated; and preferably, the warm water tank 2 is connected to a warm water pipe 4 to transfer the warm water to the germination tank 3. A water pipe 4 is passed into the germination tank 3 to introduce warm water, and the germination tank 3 is provided with a drainage mechanism for draining the water in the tank before the next input of warm water; preferably, a bucket elevator 1 for feeding is connected to the germination tank 3, and the whole grains are lifted to the top through the lower end of the bucket elevator 1. The bucket elevator 1 can automatically lift the whole grains into the germination tank 3, and the feeding speed is frequency-controlled according to the actual processing volume, and an electric butterfly valve 8 is provided at the bottom of the germination tank 3. When the germination is finished, the electric butterfly valve 8 is opened to slowly discharge the germinated whole grains to the drain mechanism, and the discharge amount is controlled by controlling the size of the butterfly valve opening.

[0043] Taking brown rice as an example, white rice, brown rice, and the germinated brown rice of the present invention were steamed separately. The texture analysis results are shown in Table 1: The brown rice had significantly higher hardness than the white rice, while the germinated brown rice of the present invention had significantly lower hardness, with no significant difference in hardness compared to the white rice. The chewiness of the brown rice was significantly different from that of the white rice, while the chewiness of the germinated brown rice of the present invention was significantly lower, with only a small difference in chewiness compared to the white rice. This demonstrates that the process of the present invention solves the problem of whole grains being difficult to steam and having a rough texture.

[0045] Table 1

[0046] Among them, the water supply mechanism includes a disc spray pipe 10 for spraying the whole grains in the germination tank 3, and a water collecting pipe for collecting the warm water after spraying. The disc spray pipe 10 and the water collecting pipe are connected, and the disc spray pipe 10 is connected to a pumping mechanism for transporting the collected warm water to the disc spray pipe 10 for spraying. Through the self-circulation generated between the disc spray pipe 10 and the water collecting pipe, the warm water can continue to spray the whole grains, ensuring that the whole grains can be fully heated and improving their own germination uniformity and effect.

[0047] Furthermore, a stirring mechanism for stirring the whole grains during spraying is provided in the germination tank 3. The preferred stirring mechanism includes a rotating shaft and a stirring paddle 7 connected to the rotating shaft. The stirring paddle 7 is evenly arranged between the top and bottom ends of the germination tank 3. The sprayed warm water can fully soak into the whole grains through stirring, ensuring that the whole grain pile in the germination tank 3 can be evenly in the germination environment, ensuring the uniformity of whole grain germination, and helping the whole grains to contact with oxygen, which is conducive to germination; preferably, the warm water is discharged after the spray self-circulation for 3-5 minutes, and warm water is injected again after an interval of 2 hours, and the spraying and stirring are turned on. The cycle is executed until the germination is completed. The germination time is different for different types of whole grains.

[0048] As a preferred embodiment of the present invention, the warm water tank is connected to an ozone generator for passing ozone into its internal warm water at equal time intervals, and then in the spraying stage, the warm water mixed with ozone is sprayed onto the whole grains in the germination tank again. Whole grains are more likely to breed microorganisms and produce odor under germination conditions because they remove the shell. The mode of regularly passing ozone can effectively inhibit bacteria and reduce odor. Preferably, ozone is passed for 20-30min every 6h during the germination process, which can be automatically controlled by a timer switch. And the passing of ozone is combined with subsequent high-temperature pre-cooking process, 115°C for 20-30min, almost all microorganisms are killed, and the shelf life can reach 12 months at room temperature. Taking brown rice as an example, the results of microbial detection during the shelf life of germinated brown rice are shown in Table 2, illustrating that the ozone disinfection process in the germination process is combined with high-temperature pre-cooking process, effectively inhibits and kills microorganisms, and extends the shelf life of the product, which can reach 12 months.

[0049]

[0050] Table 2

[0051] The germination tank 3 is connected to a cleaning mechanism for introducing water into the whole grains before germination. The tank body of the germination tank 3 is provided with an overflow port 6 for floating and overflowing impurities. The overflow port 6 is located above the whole grain pile. Therefore, before germination, water is injected into the germination tank 3 so that impurities and spoiled whole grains mixed in the whole grains can float under the action of the water flow and flow out of the germination tank 3 through the overflow port 6, thereby ensuring the cleanliness of the whole grains. Preferably, the germination tank 3 is also provided with a cold water valve and a cold water pipe 5. After the germination tank 3 is loaded, cold water is injected into the germination tank 3 through the cold water valve and the cold water pipe 5 to serve as a cleaning water flow.

[0052] The essence of sprouting whole grains is the enzymatic hydrolysis process in which a large number of enzymes contained in the whole grains are activated and released, and converted from a bound state to a free state. After sprouting, the nutrients contained in the whole grains are also increased, especially the content of γ-aminobutyric acid is increased by 5-10 times, and the functions of lowering blood lipids, lowering blood sugar, lowering blood pressure, anti-oxidation and preventing Alzheimer's disease are enhanced, and the nutritional value is improved. Moreover, the cellulose, hemicellulose, pectin and other substances in the cortex of the whole grains are partially decomposed into small molecules that are easily absorbed and digested. The sprouted whole grains are easier to digest and absorb, the taste becomes softer, and the cooking properties are improved. The whole grain sprouting equipment of the present invention is mainly composed of a bucket elevator 1, a warm water tank 2, a sprouting tank 3, a vibrating screen 9, a scraper elevator 11, a packaging machine and a high-pressure sterilizer. This set of equipment can realize automatic loading, automatic water supply and cleaning, constant temperature control, automatic timed warm water spraying, timed ozone injection for antibacterial, automatic discharging, drainage and automatic packaging. The production volume of each batch reaches 500-1000kg. According to the production needs of the enterprise, production lines can be added in parallel to realize the large-scale production of sprouted whole grains to meet the needs of the industry.

[0053] A whole grain processing method is also provided, comprising the following steps:

[0054] Loading: transport the whole grains into the germination tank 3;

[0055] Cleaning and soaking: Pour cleaning water into the germination tank 3. Start stirring when the level of the cleaning water is above the whole grains. Continue to pour cleaning water. When the level reaches the overflow port 6, continue to pour cleaning water for 3-5 minutes to clean the whole grains. Drain the cleaning water and pour the warm water in the warm water tank 2 into the germination tank 3 until the whole grains are covered. Soak for 2-4 hours and then drain the warm water.

[0056] Germination: Soak the whole grains in warm water and drain it out. Refill warm water and start the spraying cycle to cover the whole grains and stir them. After 3-5 minutes of spraying, drain the warm water and refill warm water after 2 hours. Start spraying and stirring. Repeat the cycle until germination is complete.

[0057] Discharging and draining: The sprouting tank 3 discharges the sprouted whole grains and inputs the sprouted whole grains into the vibrating screen 9, vibrates and drains the sprouted whole grains and evenly inputs them into the lifting mechanism to drain the moisture on the surface of the sprouted whole grains;

[0058] Packaging, pre-cooking and sterilization: The sprouted whole grains after the surface water is drained are lifted to the packaging machine hopper for quantitative packaging. The packaged sprouted whole grains are transferred to the high-pressure sterilization mechanism for pre-cooking and sterilization.

[0059] Preferably, in the germination step, every interval of 6h is passed into ozone 20-30min in warm water tank 2, passing into ozone and being combined with high temperature pre-ripening process, 115 ℃ of process 20-30min, almost all by microorganisms are killed, and the shelf life can reach 12 months at room temperature. Taking brown rice as example, analyzing the microbial detection results during the germinated brown rice shelf life is shown in Table 2, illustrates that the ozone disinfection process in germination process is combined with high temperature pre-ripening process, effectively suppresses, kills microorganisms, and extends the shelf life of product, can reach 12 months.
