[0063] The following will be described in combination with the drawingsFigures 1-2 The application is described in further detail.

[0064] The application discloses a fruit and vegetable juice preparation method.

[0065] With reference to Figure 1 , the fruit and vegetable juice preparation method comprises:

[0066] Q1, obtaining and identifying fruit and vegetable information, and calling matched fruit and vegetable juice preparation information from a preset database according to the fruit and vegetable information, and outputting user prompt information.

[0067] The fruit and vegetable information can be the name / image / identification number of the fruit and vegetable, which can be manually input or selected by the user. After obtaining the name of the fruit and vegetable, the information can be identified and called from the database according to the pre-stored information. The fruit and vegetable juice preparation information can be, for example, recipe / formula information, which contains the standard fruit and vegetable feeding amount and the feeding amount.

[0068] The user prompt information includes recommended feeding information, such as water and sugar.

[0069] Q2-1, obtaining the fruit and vegetable feeding amount m1; first, Q1 and Q2 in the embodiment do not refer to steps, but parts; m1 can be detected by a weight sensor installed at the bottom of the juicer (such as a food processor).

[0070] Q2-2, obtaining several of the feeding scheme, general action control scheme, stall handling scheme, and taste control action scheme according to the feeding amount m1 and the fruit and vegetable juice preparation information, and generating a juicing control plan;

[0071] Controlling the juicing equipment according to the juicing control plan; wherein the juicing control plan at least includes the general action control scheme.

[0072] As can be seen from the above, the method can automatically perform feeding, general action control, anti-stall, and taste control action adjustment according to the fruit and vegetable information input by the user, help the user to perfect the juicing control plan, improve the taste of the squeezed fruit and vegetable juice, and improve the use experience of the juicing equipment.

[0073] In the method, the general action control scheme refers to the rotation of the cutter of the juicing equipment in a relatively conventional manner to meet the basic juicing action requirement; specifically, it includes:

[0074] Setting the rotation speed v1 (such as 6500-9000 r / min) and the rotation direction b1 (such as forward rotation);

[0075] Comparing the feeding amount m1 with the standard fruit and vegetable amount m2 in the fruit and vegetable juice preparation information to obtain the ratio w1;

[0076] When w1< the lower limit of the ratio threshold, it is considered that the user's feeding amount is small, and the juicing time t1 (such as 20-30s) is set;

[0077] When the lower limit of the ratio threshold≤w1≤the upper limit of the ratio threshold, it is considered that the user's feeding amount is appropriate, and the juicing time t2 (such as 30s-40s) is set;

[0078] When w1> the upper limit of the ratio threshold, it is considered that the user's feeding amount is large, and the juicing time t3 (such as 40-50s) is set; wherein, t1≤t2≤t3.

[0079] The upper limit of the ratio threshold is 0.5-1, and the lower limit of the ratio threshold is 1-1.5. In this embodiment, the upper limit of the ratio threshold is 0.8, and the lower limit of the ratio threshold is 1.2.

[0080] The above can meet the juicing demand of fruits with more water such as watermelons and tomatoes. When the fruit and vegetable information is identified as low-moisture fruits and vegetables such as apples and carrots, that is, when the fruit and vegetable information is identified as low-moisture fruits and vegetables, the juicing control plan includes a feeding scheme and a general action control scheme, the juicing control plan includes:

[0081] A standard water addition ratio w2 is obtained, the standard water addition ratio w2 is the ratio of the feeding amount m1 to the water amount M1, a feeding scheme is generated according to the feeding amount m1 and the standard water addition ratio w2, and feeding is performed; for example, w2 can be 1:1.5-1:4.

[0082] The rotation speed v2 (8000-10000r / min) and the rotation direction b1 (such as forward rotation) are set;

[0083] The feeding amount m1 is compared with the standard fruit and vegetable amount m2 in the fruit and vegetable juicing required information to obtain the ratio w1;

[0084] When w1< the lower limit of the ratio threshold (such as 0.8), the juicing time t4 (such as 40-50s) is set;

[0085] When the lower limit of the ratio threshold≤w1≤the upper limit of the ratio threshold (such as 1.2), the juicing time t5 is set; (such as 60-70s)

[0086] When w1> the upper limit of the ratio threshold, the juicing time t6 (such as 80-90s) is set; wherein, t4≤t5≤t6.

[0087] As can be seen from the above, when the fruit and vegetable contains less water, the method corresponds to water addition, and the juicing action is adjusted according to the latest feeding amount, so that the low-moisture fruits and vegetables can be successfully juiced.

[0088] In the method, if the fruit and vegetable is a fruit and vegetable with a relatively hard texture, it is considered that the juicing process is relatively prone to stalling, and therefore it is provided that: if it is detected that the working parameter of the driving unit in the juicing process meets the preset stalling condition, it is determined that the cutter head stalls, and a stalling processing scheme is generated.

[0089] The preset stalling condition includes: continuously detecting the working current of the driving unit (such as the stirring cutter head) in the juicing process, and if the working current is greater than or equal to the set current threshold, it is determined that the cutter head stalls.

[0090] Referring to Figure 2 , the stalling processing scheme includes:

[0091] adjusting the rotation speed to v3 (such as 1000-2000 r / min), v3 < v1, which can be considered as a low rotation speed;

[0092] When the rotation speed of the juicing device reaches v3, the rotation direction is changed to b2, and b2 is different from b1;

[0093] for a duration of T1 (such as 3-5 seconds), the rotation direction is changed to b1;

[0094] for a duration of T1, the rotation direction is changed to b2 again;

[0095] The b1 and b2 switching is repeated multiple times until the working parameter does not meet the preset stalling condition, and the rotation speed of the cutter head returns to the original rotation speed (which is considered to be a high rotation speed).

[0096] For low-moisture fruit and vegetables, the rotation speed and direction can be directly adjusted; and for high-moisture fruit and vegetables, after identifying the stall, water needs to be added to relieve the crushing resistance, and then the rotation speed and direction are adjusted according to the above method. Specifically, if the fruit and vegetable information is identified as a high-moisture fruit and vegetable, before adjusting the rotation speed to v3, it further includes: when the working parameter meets the preset stalling condition, obtaining a stalling prevention water amount M2, and injecting M2 of water.

[0097] Obtaining the stalling prevention water amount M2 includes:

[0098] When w1 < the lower limit threshold of the ratio, set the water amount g1 (such as 50 g);

[0099] When the lower limit threshold of the ratio ≤ w1 ≤ the upper limit threshold of the ratio, set the water amount g2 (such as 60 g);

[0100] When w1 > the upper limit threshold of the ratio, set the water amount g3 (such as 70 g); wherein g1 ≤ g2 ≤ g3.

[0101] In this embodiment, the time for adjusting the stall is not more than 20 seconds by default, and is not counted in the overall cooking time of the fruit and vegetable; after the stall is removed, the original high crushing rotation speed is restored, and the rotation speed increasing rate can be slowly increased or quickly increased.

[0102] The reason why water needs to be added to fruits and vegetables with high water content, rather than those with low water content, when the juicer becomes clogged is because: high-water-content fruits and vegetables, such as watermelon, do not require added water for juicing; adding water during clogging primarily reduces agitation resistance. Low-water-content fruits and vegetables, such as apples, already have water added during juicing; in this case, adding water will not solve the problem of clogging, and the main solution is to rotate the blades in both directions.

[0103] like Figure 3 The document shows the water content of the edible parts of some fruits and vegetables. In this application, high-moisture fruits and vegetables are those with a water content of more than 90% in the edible parts, and low-moisture fruits and vegetables are those with a water content of less than 90% in the edible parts.

[0104] Understandably, timing is required during the juicing process. When high-speed rotation is considered normal, timing is started at high speed and it is determined whether the timing duration is greater than or equal to the predetermined duration. If so, the juicing process ends.

[0105] In another embodiment of this method, considering that the lemon is heated during the stirring process, the activity of the limonene hydrolase in the lemon increases, leading to more bitter substances dissolving in the lemon juice and resulting in a bitter taste; therefore, when juicing fruits and vegetables containing limonene, such as lemons and citrus fruits, the following settings are made: if the fruit and vegetable information is identified as containing limonene, the juicing control plan includes a feeding scheme, and the feeding scheme includes adding sugar, the feeding scheme including:

[0106] Based on the ratio w1, the recommended sugar addition amount m4 and the recommended water addition amount m5 are set, and the actual sugar addition amount m6 is obtained.

[0107] Establish the formula w2=m6 / m4 and calculate it;

[0108] When w2 meets the standard threshold range (e.g., 0.95-1.05), water addition should be controlled using the recommended water addition volume m5.

[0109] When w2 is less than the standard threshold range, the predefined proportional coefficient k1*m5, which is less than 100%, is used to obtain a new water addition amount, and water addition control is performed.

[0110] When w2 is greater than the standard threshold range, the predetermined proportional coefficient k2*m5, which is greater than 100%, is used to obtain the new water addition amount, and water addition control is performed.

[0111] If the fruit and vegetable information is identified as containing limonene, the juicing control plan also includes a taste control action plan; the taste control action plan includes:

[0112] Rotating at the rotating speed v3 (such as 5000~6000 r / min) for a time length T4 (such as 2~5s), stopping the juicing action for a time length T5 (such as 2~3s), and then rotating at the rotating speed v3 for a time length T4 again; after the cycle N2 (such as 2~4) times, rotating at the rotating speed v4 (such as 8500~10000 r / min) for a time length T4, stopping the juicing action for a time length T5, and then rotating at the rotating speed v4 for a time length T4 again; after the cycle N3 times, the juicing is ended; wherein, v4>v3;

[0113] wherein, the cycle number N2 is n4, and n4 is greater than 0;

[0114] The calculation method of the cycle number N3 comprises:

[0115] When the ratio lower threshold value≤w1≤the ratio upper threshold value, the cycle number N3 is n5 (such as 2~5 times);

[0116] When w1

[0117] When w1>the ratio upper threshold value, the cycle number N3 is n7 (such as 7~10 times); wherein, n7>n5>n6.

[0118] The ratio upper threshold value is 0.5~1, and the ratio lower threshold value is 1~1.5; in the embodiment, the ratio upper threshold value is 0.95, and the ratio lower threshold value is 1.05.

[0119] In the taste control action scheme, the cutting is first performed at the lower rotating speed v3 to reduce the temperature rise, thereby reducing the activity of the bitter principle hydrolytic enzyme in the lemon; and then the crushing is performed at the higher rotating speed v4 to ensure the juicing function.

[0120] If the fruit and vegetable information is identified as the fruit and vegetable class containing the lemon bitter principle, the juicing control plan further comprises a taste control action scheme; the taste control action scheme comprises:

[0121] Rotating at the constant rotating speed v5 (such as 8000~9000 r / min) for a time length T2 (such as 2~5s), stopping the juicing action for a time length T3 (such as 2~3s), and then rotating at the constant rotating speed v5 for a time length T2 again; after the cycle number N1 times, the juicing is ended;

[0122] The calculation method of the cycle number N1 comprises:

[0123] When the ratio lower threshold value≤w1≤the ratio upper threshold value, the cycle number N1 is n1 (such as 2~6 times);

[0124] When w1

[0125] When w1 > the upper limit threshold of the ratio, let the number of cycles N1 be n3 (e.g., 9 to 15 times); where n3 > n1 > n2.

[0126] Based on the above settings:

[0127] 1) A non-bitter lemon juice can be prepared by a high-frequency short-time grinding method to prevent the temperature of the blades and food inside the cavity from rising too high due to long-term high-speed stirring, which would increase the activity of the bitter enzyme in lemon and cause more bitter substances to dissolve in the lemon juice, resulting in a bitter taste.

[0128] 2) By detecting the weight of fresh lemons used, the system recommends a reasonable amount of sugar to users. Compared with a single recipe specification, the amount of sugar added is adjusted in real time according to the standard ratio of lemons to sugar, which better meets the actual needs of users.

[0129] 3) Based on the actual weight of lemons and the amount of sugar added by the user, analyze in real time and automatically match the appropriate amount of water to avoid the lemon juice being too sweet or too sour due to the user not adding sugar according to the recommended amount.

[0130] This application also discloses a fruit and vegetable juice preparation system.

[0131] The fruit and vegetable juice preparation system includes:

[0132] The information acquisition module is used to acquire information about fruits and vegetables and the amount of fruits and vegetables fed into the system, m1.

[0133] The processing module is used to retrieve the matching information required for juicing fruits and vegetables from a preset database based on the fruit and vegetable information, and output user prompts.

[0134] Furthermore, it is used to generate a juicing control plan by obtaining several of the following based on the feeding amount m1 and the information required for fruit and vegetable juicing: feeding scheme, general action control scheme, stall handling scheme, and taste control action scheme; and to control the juicing equipment according to the juicing control plan; wherein the juicing control plan includes at least the general action control scheme.

[0135] The juicing control plan has been described in the embodiments of the aforementioned method, and therefore will not be repeated here.

[0136] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
