Description

Technical Field

[0001] The invention relates to bean product processing equipment, and more particularly to an additive-free full-automatic bean sprout cultivation machine. Background Art

[0002] Beans refer to all leguminous plants that can produce pods. There are many varieties of beans, rich in nutrition, and they are cultivated all over the world. In recent years, beans have become more and more popular due to their high nutritional value and good taste.

[0003] The main nutrients in beans include carbohydrates, proteins and fats, etc. Protein in beans is an important component of beans.

[0004] ① Protein: The content of 8 essential amino acids needed by the human body in bean protein is very reasonable compared with the ideal value recommended by the Food and Agriculture Organization of the United Nations (FAO). Bean protein has a good amino acid composition pattern, rich in glutamic acid, alanine and aspartic acid, and contains high lysine, but low in methionine and tryptophan (sulfur-containing amino acids). Some grains have high sulfur-containing amino acids and low lysine. Therefore, when eating beans, you can appropriately pair them with some grain foods. This can play a role in protein complementation, thereby improving the nutritional value of food.

[0005] ②Fat: Soybeans and black beans have a higher fat content, while other beans besides soybeans and black beans, such as kidney beans, have a lower fat content, but their fatty acid composition pattern is better, mainly polyunsaturated fatty acids, mainly including linoleic acid, linolenic acid, etc.

[0006] ③Vitamins: Beans contain vitamin A, vitamin B, vitamin C, and vitamin E.

[0007] ④Minerals: Different beans contain different minerals. For example, soybeans are rich in iron, while kidney beans contain calcium, iron, potassium and magnesium.

[0008] ⑤Dietary fiber: Beans contain dietary fiber, which has many benefits to the body.

[0009] ⑥ Pigment: Soy isoflavones are a type of flavonoid compound, mainly found in leguminous plants. Flavonoid compounds are a type of plant pigment. Soy isoflavones are a type of secondary metabolite formed during the growth of soybeans. They can make up for the deficiency of insufficient estrogen secretion in women after the age of 30, improve skin moisture and elasticity, relieve menopausal syndrome and improve osteoporosis. The estrogenic effect of soy isoflavones affects hormone secretion, metabolic biological activity, protein synthesis, and growth factor activity, and is a natural cancer chemopreventive agent.

[0010] Beans can be made into various processed foods for consumption. For example, bean sprouts obtained by culturing and germinating beans are a commonly used bean product.

[0011] In order to standardize and scale up bean sprout processing, it is necessary to adopt mechanical and automated cultivation equipment. The technical problem of the bean sprout cultivation machine in the prior art is that the nozzle spraying method is adopted, and there is a problem that the local temperature is too high and affects the growth of bean sprouts.

[0045] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and is not a limitation of the scope of protection, applicability or examples set forth in the claims. The functions and arrangements of the elements discussed can be changed without departing from the scope of protection of the contents of this specification. Various examples can omit, replace or add various processes or components as needed. For example, the described method can be performed in an order different from the described order, and various steps can be added, omitted or combined. In addition, the features described relative to some examples can also be combined in other examples.

[0046] In this embodiment, a non-additive fully automatic bean sprout cultivation machine is provided. Figure 1 FIG. 1 is a schematic diagram of a non-additive fully automatic bean sprout cultivation machine according to the present invention. Figure 1-3 As shown, the additive-free fully automatic bean sprout cultivation machine includes:

[0047] The machine body 100 has a space for accommodating bean sprouts, and a filtering mechanism 200 for carrying the bean sprouts is provided in the space; a spraying mechanism 300 for spraying is provided on the top of the machine body 100, and a drainage mechanism 400 for drainage is provided on the side;

[0048] The filter mechanism 200 divides the internal space of the body 100 into two parts, the upper and lower parts. The filter mechanism 200 is provided with a plurality of through holes connecting the upper and lower parts.

[0049] The spray mechanism 300 includes a top cover 310 disposed on the top of the body 100, a chamber is disposed inside the top cover 310, a spray pipe 320 is disposed on the top cover 310 and connected to the chamber inside the top cover 310, and a plurality of spray holes 330 are disposed at the bottom of the top cover 310 and connected to the chamber inside the top cover 310. Pure water enters the chamber inside the top cover 310 from the spray pipe 320 and is distributed to the plurality of spray holes 330 and then evenly sprayed onto the bean sprouts contained inside the body 100.

[0050] The drainage mechanism 400 includes three drainage holes, each of which is provided with a main valve 410 and two auxiliary valves 420. The main valve 410 is a pressure relief valve. As the amount of water inside the body 100 increases, the pressure of the drainage hole of the main valve 410 increases, so that the water level inside the body 100 is kept at a low level.

[0051] The main valve 410 may be a valve with a pressure relief function in the prior art. This embodiment provides a specific implementation method: a valve plate is provided on the drain hole, and the valve plate is connected to the body 100 through an elastic member. The internal water pressure overcomes the elastic force of the elastic member to open the valve to drain water.

[0052] The elastic parts may include but are not limited to: tendon rope, spring, rubber band.

[0053] The two auxiliary valves 420 are solenoid valves connected to a solenoid valve controller, and the opening is controlled by the solenoid valve controller, so that the valves can be opened for drainage after soaking the bean sprouts or when washing;

[0054] The spray pipe 320 is provided with a spray valve for controlling the spray flow rate.

[0055] The inner edge of the top opening of the body 100 is concave downward to form a circle of steps, and the top cover 310 is embedded in the top opening of the body 100, and the bottom contacts the step on the top of the body 100, and a sealing ring is provided on the step. The embedded top cover 310 can eliminate a gap between the top cover 310 and the body 100.

[0056] The filter mechanism 200 is a mesh plate detachably connected to the body 100 .

[0057] The bottom of the machine body 100 is also provided with a walking mechanism for easy movement, and the walking mechanism can be selected from but not limited to: unpowered walking wheels or powered walking wheels, and the powered walking wheels can be connected to a driving mechanism such as a motor;

[0058] This embodiment provides a bean sprout cultivation method based on the above-mentioned additive-free fully automatic bean sprout cultivation machine:

[0059] First, the tap water is sterilized at high temperature to obtain pure water, and the storage barrels are also sterilized at high temperature;

[0060] Then add the sterilized purified water into the storage bucket, then add a predetermined amount of mung beans into the storage bucket and soak for 4 hours;

[0061] The predetermined amount of mung beans should be in a predetermined ratio to the weight of the purified water added during soaking, for example, the weight ratio of mung beans to purified water is 1:2.

[0062] Then, the soaked mung beans are filtered out and transported to the above-mentioned fully automatic bean sprout cultivation machine;

[0063] Non-toxic pure water at 20-23°C is sprayed out through the spray ports evenly distributed on the cover of the bean sprout machine to provide moisture for the growth of bean sprouts. After the bean sprouts have grown for a predetermined time, they are taken out to obtain bean sprout products.

[0064] The expected growth time for bean sprouts is 4-6 days.

[0065] Under ideal conditions, there is such a relationship in the system of substances in the body 100, within the predetermined time of bean sprout growth:

[0066] C = Q / ΔT, where C represents the average heat capacity, ΔT represents the temperature difference, and Q represents the variable of heat within the temperature difference range of ΔT;

[0067] The total heat released by the bean sprouts inside the body 100 during the growth process is a fixed value. The change in total heat can be calculated from the loss of mass according to the law of conservation of matter. A fixed amount of mung beans can be taken to sprout in a simulated environment to measure the temperature difference, and the mass lost by the bean sprouts can be weighed to calculate the heat variable and the average heat capacity C.

[0068] The above relationship can be transformed to obtain ΔT = Q / C;

[0069] The heat released during the growth of bean sprouts inside the body 100 increases with time, so it can be determined that in order to maintain a constant temperature inside, the amount of spray water per unit time h is proportional to time;

[0070] like Figure 4 As shown, when the machine body 100 contains 100 kg of mung beans, the predetermined heat function graph f(t) released during the growth of bean sprouts is shown in the figure, where the constant coordinate is time t and the ordinate is the heat release speed q;

[0071] Correspondingly, the predetermined spray water flow rate function graph h(t) of the predetermined spray water flow rate V varying with time t is as follows: Figure 5 As shown, the spray water flow rate V reflects the amount of spray water per unit time. The amount of spray water produces a heat dissipation proportional to it, which also represents the speed of heat dissipation.

[0072] However, in actual situations, the actual heat function image F(t) may deviate from the predetermined heat function image f(t) due to various factors such as the origin and density during the growth of mung beans. As shown in the figure, the actual heat function image F(t) is compressed in the horizontal direction compared with the predetermined heat function image f(t), that is, the slope of the heat function image F(t) becomes larger. Another possibility is the opposite of the situation shown in the figure.

[0073] This will cause the predetermined constant temperature condition to be broken, because the change in the heat function graph also means that the amount of heat released at the same time has changed, while the heat dissipation generated by the predetermined spray water volume has not changed, which will lead to a rise in temperature (as shown in the figure);

[0074] like Figure 4 As shown, when the horizontal axis corresponds to the time node of 5 minutes, the heat release rate q of the actual heat function image F(t) increases by 800 J / min compared with the predetermined heat function image f(t), and a temperature difference of 0.3°C is generated within the time node of 5 minutes;

[0075] It should be noted that, in the above function graph, the horizontal axis representing time t has 1 minute as one coordinate point.

[0076] Since there is such a formula ΔT=Q / C, by measuring a temperature value at the front and back ends of the time node corresponding to 5 minutes respectively, we can get the temperature difference ΔT5 within the time node of 5 minutes, and then we can calculate the total heat release within the time node of 5 minutes Q5=ΔT5*C, that is, the heat release rate on the vertical axis corresponding to the horizontal axis of the time node of 5 minutes q5=Q5 / t5, t5=1min, which can be simplified to q5=Q5 / 1min.

[0077] More specifically, the above process can be summarized to obtain a method for constant temperature control inside the body 100:

[0078] Initially, a predetermined heat function image f(t) and a predetermined spray flow rate function h(t) are stored;

[0079] Measuring the start and end temperatures of the current minute inside the body 100, and calculating the temperature difference of the current minute;

[0080] Calculate the actual heat release rate in the current minute based on the temperature difference in the current minute;

[0081] Calculate the predetermined heat release rate of the current minute according to the predetermined heat function image f(t);

[0082] Calculate the ratio g of the actual heat release rate to the predetermined heat release rate corresponding to the current minute;

[0083] Correcting the predetermined spray flow rate function h(t) to obtain a corrected spray flow rate function H(t), H(t)=gh(t);

[0084] The spray flow rate is controlled by correcting the spray flow rate function H(t) to achieve a constant temperature inside the body 100.

[0085] Based on such a principle, a control system 500 is designed, including:

[0086] The sensor 510 is used to detect the internal temperature of the body 100;

[0087] The temperature difference calculation unit 520 receives the temperature data sent by the sensor 510 and calculates the temperature difference within the current minute;

[0088] The heat release rate calculation unit 530 receives the temperature difference in the current minute calculated by the temperature difference calculation unit 520, and calculates the actual heat release rate in the current minute;

[0089] The function correction unit 540 receives the actual heat release rate calculated by the heat release rate calculation unit 530, calculates the ratio g of the actual heat release rate to the predetermined heat release rate corresponding to the current minute, and uses the ratio g as a weighted value to correct the predetermined spray flow rate function h(t) to obtain a corrected spray flow rate function H(t);

[0090] The flow controller 550 receives the corrected spray flow rate function H(t) obtained by the function correction unit 540, and controls the spray flow rate by correcting the spray flow rate function H(t).

[0091] The flow controller 550 initially stores a predetermined spray flow rate function h(t). After receiving the corrected spray flow rate function H(t) obtained by the function correction unit 540, the corrected spray flow rate function H(t) replaces the initial predetermined spray flow rate function h(t).

[0092] The result of the correction should be such that the lateral compression ratio of the actual heat function image F(t) compared to the predetermined heat function image f(t) is the same as the lateral compression ratio of the corrected spray flow rate function H(t) compared to the predetermined spray flow rate function h(t).

[0093] Optionally, the flow controller 550 controls the spray flow by controlling the opening of the spray valve.
