Description

Technical Field

[0001] This invention relates to the field of food technology, and in particular to a red rice grinding and processing device. Background Technology

[0002] Red rice is pinkish-red, glutinous, with extra-long grains, and has a fragrant aroma. It contains various trace elements. Red rice wine, brewed from red rice, is particularly popular among women because it has a red color similar to red wine, a mellow taste, and a pleasant aftertaste. Experiments have shown that red rice can increase plasma high-density lipoprotein cholesterol (HDL) and improve the body's antioxidant capacity, which is also of great significance in the prevention and treatment of atherosclerosis and other chronic diseases.

[0003] Edible fungi contain bioactive substances such as high-molecular-weight polysaccharides, β-glucose and RNA complexes, natural organic germanium, nucleic acid degradation products, cAMP and triterpenoids, which have important value in maintaining human health.

[0004] Red rice and edible fungi can be combined in food to supplement nutrition; currently, food ingredients are often made into powder products, which are prone to absorbing moisture, especially if accidentally exposed to air, they are easy to absorb moisture and spoil; this is not conducive to bulk sales.

[0039] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below through specific embodiments.

[0040] Example 1

[0041] The steps of the red rice edible fungus nutritional powder preparation method provided in this embodiment are as follows:

[0042] S1. Red rice is ground into powder and then mixed with 2.5 times its weight of water and gelatinized at 80°C for 2.5 hours to obtain a gelatinized product.

[0043] S2 mixes cordyceps, black fungus, and wolfberry in a weight ratio of 2:3:3, adds 2.5 times the total mass of water to the mixture, boils at room temperature and pressure for 1.2 hours, and then filters to obtain an aqueous extract.

[0044] S3 dried the white fungus, made it into powder, added 25 times its weight of water, boiled and kept for 2.5 hours, and then filtered to obtain the white fungus gelatinous substance.

[0045] S4 mixes and homogenizes the gelatinized material, water extract and tremella gelatinous material in a weight ratio of 1:1:1, and then concentrates it to obtain a paste with a water content of 50%.

[0046] S5 mixes the obtained paste, tremella gelatin, sodium alginate, and carrageenan in a weight ratio of 110:80:2:4, and then freeze-dries them to obtain a nutrient powder with a moisture content of less than 10%.

[0047] This embodiment uses a red rice edible fungus nutritional powder made from cordyceps, black fungus, goji berries, red rice, and white fungus. First, a stable cross-linked paste is formed by combining the gelatinized material, water extract, and white fungus gelatinous material. Then, white fungus gelatinous material, sodium alginate, and carrageenan are added to create a certain physical barrier, giving the resulting nutritional powder moisture-proof properties without affecting its solubility. (Since the paste contains 40%-60% water, the water evaporates during freeze-drying, causing the gelatinized material to shrink in volume. Sodium alginate (an adhesive) has certain adhesive properties, allowing it to more completely coat the paste. Simultaneously, I-type carrageenan interacts with calcium ions to form a soft texture.) The elastic gel, after dehydration, forms a gel-like substance that can coat the paste-like material. The main components of the tremella gel-like material are mucin and plant polysaccharides, which also become gel-like after freeze-drying. Combined with sodium alginate (an adhesive) and carrageenan, it can achieve a similar coating effect to cabbage (a layered structure where each layer doesn't necessarily completely enclose the innermost layer, but with many layers, the inner paste-like material is enclosed), forming a physical barrier and providing moisture protection. Furthermore, the outer coating is water-soluble, so the solubility is not affected during the soaking process.

[0048] Example 2

[0049] The steps of the red rice edible fungus nutritional powder preparation method provided in this embodiment are as follows:

[0050] S1. Red rice is ground into powder and then mixed with three times its weight of water. The mixture is then gelatinized at 75°C for 3 hours to obtain a gelatinized product.

[0051] S2 mixes cordyceps, black fungus and wolfberry in a weight ratio of 1:5:2, then adds water three times the total mass of the mixture and boils at room temperature and pressure for 1 hour. After filtration, an aqueous extract is obtained.

[0052] S3 dried the white fungus, made it into powder, added 30 times its weight of water, boiled and kept for 2 hours, and then filtered to obtain the white fungus gelatinous substance.

[0053] S4 mixes the gelatinized material, water extract and tremella gelatinous material in a weight ratio of 3:1:3, homogenizes and concentrates to obtain a paste with a water content of 40%.

[0054] S5 mixes the obtained paste, tremella gelatin, sodium alginate, and carrageenan in a weight ratio of 120:70:3:5, and then freeze-dries them to obtain a nutrient powder with a moisture content of less than 10%.

[0055] In this embodiment, the red rice edible fungus nutritional powder is made by blending cordyceps, black fungus, wolfberry, red rice and white fungus. Because the gelatinized material, water extract and white fungus gel are first made into a stable cross-linked paste, and then white fungus gel, sodium alginate and carrageenan are added to form a certain physical isolation, the resulting nutritional powder has moisture-proof properties, but does not affect its solubility.

[0056] Example 3

[0057] The steps of the red rice edible fungus nutritional powder preparation method provided in this embodiment are as follows:

[0058] S1. Red rice is ground into powder and mixed with twice its weight of water. The mixture is then gelatinized at 85°C for 2 hours to obtain a gelatinized product.

[0059] S2 mixes cordyceps, black fungus, and wolfberry in a weight ratio of 3:2:4, adds twice the total mass of water to the mixture, boils at room temperature and pressure for 1.5 hours, and then filters to obtain an aqueous extract.

[0060] S3 dried the white fungus, made it into powder, added 20 times its weight of water, boiled and kept for 2.5 hours, and filtered to obtain white fungus gelatinous substance;

[0061] S4 mixes and homogenizes the gelatinized material, water extract and tremella gelatinous material in a weight ratio of 1:3:1, and then concentrates it to obtain a paste with a water content of 60%.

[0062] S5 mixes the obtained paste, tremella gelatin, sodium alginate, and carrageenan in a weight ratio of 100:90:1:5, and then freeze-dries them to obtain a nutrient powder with a moisture content of less than 10%.

[0063] In this embodiment, the red rice edible fungus nutritional powder is made by blending cordyceps, black fungus, wolfberry, red rice and white fungus. Because the gelatinized material, water extract and white fungus gel are first made into a stable cross-linked paste, and then white fungus gel, sodium alginate and carrageenan are added to form a certain physical isolation, the resulting nutritional powder has moisture-proof properties, but does not affect its solubility.

[0064] Comparative Example 1

[0065] The preparation method of red rice edible fungus nutritional powder is the same as that in Example 1, except that the silver ear fungus gelatinous substance added in step S5 is added in step S4.

[0066] Comparative Example 2

[0067] The preparation method of red rice edible fungus nutritional powder is the same as that in Example 1, except that the silver ear fungus gelatinous substance added in step S4 is added in step S5.

[0068] Comparative Example 3

[0069] The preparation method of red rice edible fungus nutritional powder is the same as that in Example 1, except that the silver ear fungus gelatinous substance is not added in steps S4 and S5.

[0070] To verify the moisture-proof effect of the specific embodiments and comparative examples of the present invention, the following tests were conducted: Test 1

[0071] The moisture content of the red rice edible fungus nutritional powder obtained in Example 1 and Comparative Examples 1-3 was tested after being placed at 40℃ and 95% humidity for 6 hours.

[0072] sample Moisture content Example 1 18％ Comparative Example 1 32％ Comparative Example 2 36％ Comparative Example 3 45％

[0073] As can be seen from the above, the tremella gelatinous substance of this application can improve its moisture-proof effect.

[0074] Experiment 2

[0075] At 25°C, the sample and water were mixed at a weight ratio of 1:25 and stirred at the same speed. The time required for complete dissolution was measured. The standard for complete dissolution was that no obvious solid was visible to the naked eye.

[0076] sample Dissolution time Example 1 Within 10s Comparative Example 1 Within 10s Comparative Example 2 Within 10s Comparative Example 3 15～20s

[0077] As can be seen from the above, the gelatinous substance of tremella can increase the dissolution rate.

[0078] Example 5

[0079] A red rice crushing and processing device includes an air compressor, an air tank, an air pump, a drying filter, a cylinder, an electrostatic generator, and several pipes;

[0080] The air compressor includes an inlet and an outlet, and the dryer filter is installed at the inlet of the air compressor;

[0081] The air storage tank includes an inlet and an outlet, and the inlet of the air storage tank is connected to the outlet of the air compressor via a pipeline;

[0082] The air pump includes an inlet and an outlet, and the inlet of the air pump is connected to the outlet of the air storage tank through a pipe.

[0083] The cylinder includes a main body, a Laval nozzle, and multiple electrode plates. The bottom of the main body is tapered and has a discharge port. The Laval nozzle is located at the top inside the main body and directly above the discharge port, and is connected to the outlet of the air pump through a pipe. The side wall of the main body has a sealable inlet and a pressure relief port. The discharge port is equipped with a discharge valve, and the pressure relief port is equipped with a pressure relief valve. The electrode plates are connected below the Laval nozzle and are electrically connected to the electrostatic generator.

[0084] The device includes a working state, a discharging state, and a cleaning state;

[0085] In the aforementioned working state, the electrode plate carries a positive charge, the feed inlet is closed, the discharge valve is closed, the pressure relief valve releases pressure when the Laval nozzle is not spraying, and the air compressor, air pump, dryer filter, and electrostatic generator are working.

[0086] When the material is discharged, it carries a negative charge, the inlet is closed, the outlet valve is open, the pressure relief valve is closed, and the air compressor, air pump, dryer filter, and electrostatic generator are working.

[0087] During the cleaning state, the system is de-energized, the feed inlet is open, the discharge valve is open, the pressure relief valve is closed, and the air compressor, air pump, dryer filter, and electrostatic generator are operating.

[0088] As described above, the airflow discharged by the air pump impacts the red rice at the bottom of the Laval nozzle impact body, causing the red rice to be partially crushed and producing a certain amount of powder. Due to the airflow, the powder floats inside the cylinder. Due to the electrode plate, electrostatic adsorption occurs, causing some of the red rice powder to concentrate at the nozzle outlet. The next impact from the nozzle carries this powder and impacts the red rice pile again, repeating the cycle. This demonstrates that the powder impacts the red rice, thus increasing the degree of crushing. Therefore, there is no need to add material to the nozzle (existing technologies use the addition of harder materials for auxiliary crushing; however, this application uses a product where adding hard materials would not achieve 100% separation, or achieving 100% separation would be very costly, and there is a risk of users breaking their teeth if they bite on the hard material; therefore, this method of adding hard materials is not used for crushing). This accelerates the crushing process, eliminating the need for additional separation and material feeding, saving costs. To minimize costs, this method uses impact crushing of red rice powder, where smaller particles collide with larger ones. Both experience the same force, but the smaller particles have a larger contact area, resulting in less localized stress on the smaller particles and greater localized stress on the larger ones. This leads to the larger particles being crushed. Although the process is slower, it avoids introducing impurities, which is especially important for food products as removing impurities is tedious and excessive processing can easily lead to spoilage. Furthermore, the pressure relief valve reduces internal pressure and gas density, lowering resistance and enhancing the impact effect and efficiency. The sealable feed inlet ensures that the impact energy remains within the cylinder, preventing energy leakage. During operation, the electrode plates carry a positive charge for easy adsorption; upon discharge, they carry a negative charge to neutralize any positively charged powder, reducing floating powder and facilitating discharge. The cleaning device is de-charged, preventing powder adsorption and simplifying cleaning.

[0089] Furthermore, the end of the electrode plate furthest from the Laval nozzle is folded outwards.

[0090] As can be seen from the above description, by folding the end of the electrode plate outward, the adsorption area can be increased, thereby allowing more powder to be adsorbed, and thus more powder to participate in the impact during impact.

[0091] Furthermore, the cylinder also includes a plurality of rotating cleaning nozzles disposed on the top of the inner wall of the cylinder, and the plurality of rotating cleaning nozzles are evenly distributed around the Laval nozzle as the center;

[0092] The rotary cleaning nozzle operates in both the discharge and cleaning states.

[0093] As can be seen from the above description, by rotating the cleaning nozzle, pre-cleaning can be performed when the device ends its operation, thereby reducing the workload during cleaning.

[0094] Furthermore, the rotary cleaning nozzle is connected via a valve to a pipe between the Laval nozzle and the outlet of the air pump.

[0095] Furthermore, a filter assembly is provided on the pressure relief port.

[0096] As can be seen from the above description, the powder overflow can be prevented by setting up the filter components.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
