[0002] With the rapid development of economy and technology, and with the annual increase in labor costs, the taste requirements for meals are getting higher and higher. The taste of meals depends entirely on the skills of the chefs. Can the good taste be stable and can the skills of the chefs be passed on? The market is in urgent need of special cooking equipment that can truly replace chefs to achieve standard, stable, easy to manage, easy to operate and inheritable cooking.

[0003] With the emergence of cooking machines or cooking equipment, cooking machines can now replace manual labor to achieve processes such as stir-frying, adding oil, automatic heating and adding food, and can automatically operate according to important parameters such as set time and temperature.

The cooking machines currently available on the market use salt water, monosodium glutamate water, etc. to dissolve solid seasonings into liquids and then automatically add them to the cooking machine. This method brings extra water, and the finished product has poor flavor and can only be used for large pot dishes with low requirements. However, the disadvantage is that the existing cooking machines cannot automatically add solid seasonings such as salt, sugar, monosodium glutamate, chicken essence and pepper, etc., so the cooking machines cannot achieve fully automated solid seasoning delivery.

[0045] The feeding drive reducer 5 is connected to a spiral structure, which is located at the discharge end of the storage box 2 (i.e., the bottom end of the storage box 2). The spiral structure leads to the interior of the storage box 2. The feeding drive reducer 5 is used to drive the spiral structure to quantitatively transport the seasoning inside the storage box 2. Because the feeding drive reducer 5 drives the spiral structure at the discharge end of the storage box 2, the spiral structure transports the seasoning in the storage box 2 to the conveying pipe 4 through the air shutoff 3. In addition, the feeding drive reducer 5 is connected to a controller (not shown in the figure) for controlling the rotation speed of the feeding drive reducer 5.

[0046] The feed drive reducer 5 is used to drive the spiral structure. When the speed of the feed drive reducer 5 remains unchanged, the pitch of the spiral structure is changed so that the seasoning inside the storage box 2 can be adjusted and quantitatively transported; or the feed drive reducer 5 is connected to a controller for controlling the speed of the feed drive reducer 5. When the pitch of the spiral structure remains unchanged, the speed of the feed drive reducer 5 is adjusted so that the seasoning inside the storage box 2 can be adjusted and quantitatively transported;

[0047] The spiral structure of the present invention is the spiral mechanism 5 disclosed in Chinese patent CN202037725U, and the spiral mechanism 5 disclosed in Chinese patent CN202037725U is arranged at the discharge end of the material storage box 2.

[0054] Example 2

[0055] Based on Example 1, the working principle of the present invention is:

[0056] The spiral structure is driven by the feed drive reducer 5, and the spiral structure quantitatively delivers the seasoning in the storage box 2. The rotary blades in the air lock 3 are driven by the air lock reducer 7 to rotate, and the seasoning in the storage box 2 is delivered to the delivery pipe 4 through the air lock 3. After the seasoning passes through the discharge pipe 9 and the air lock 3, the seasoning is delivered to the delivery pipe 4. Here, the rotation speed of the feed drive reducer 5 and the pitch of the spiral structure determine the metered delivery of the seasoning, and the rotation speed of the feed drive reducer 5 and the pitch of the spiral structure are determined according to the delivery situation.

[0057] The rotating blades inside the air lock 3 rotate to quantitatively transport the seasoning inside the storage box 2 to the delivery pipe 4, and at the same time, the air pump 6 is turned on, and the seasoning inside the delivery pipe 4 is blown to the outside of the delivery pipe 4 by the air pump 6. In this way, the air lock 3 quantitatively transports the seasoning inside the storage box 2 to the delivery pipe 4, and at the same time, the air pump 6 blows the seasoning inside the delivery pipe 4 to the outside of the delivery pipe 4, and no seasoning is stored in the delivery pipe 4, and the seasoning inside the storage box 2 is completely transported to the outside of the delivery pipe 4.

[0058] Example 3

[0059] Based on Example 1, Figure 5 As shown, the air shutoff 3 is replaced by a valve member 11 , and the valve member 11 is disposed between the discharge pipe 9 and the inclined pipe 12 , and the valve member 11 is connected to the discharge pipe 9 and the inclined pipe 12 .

[0060] The valve member 11 leads to the conveying pipeline 4 through the inclined pipe 12 .

[0061] The inclination angle of the inclined tube 12 to the horizontal plane ranges from 30° to 50°, and the inclined tube 12 facilitates buffering of the seasoning in the discharge pipe 9 to be transported into the transport pipeline 4 .

[0062] Figure 5 The working principle is:

[0063] The valve member 11 is opened to drive the spiral structure through the feed drive reducer 5, and the spiral structure quantitatively delivers the seasoning in the storage box 2 to the delivery pipeline 4 through the discharge pipe 9, the valve member 11 and the inclined pipe 12. The valve member 11 is closed, and the air pump 6 is turned on, and the air pump 6 blows the seasoning in the delivery pipeline 4 to the outside of the delivery pipeline 4.

[0064] Example 4

[0065] Based on Example 1 and Example 2, this embodiment provides an automatic metering and conveying method of a powder seasoning automatic metering and conveying device, comprising the following steps:

[0066] Step 1): Put solid seasoning into the storage box 2;

[0067] Step 2): The feed drive reducer 5 is driven to rotate by the controller, and the controller uses a speed fine-tuning method to adjust the speed of the feed drive reducer 5;

[0068] Step 3): convey the seasoning in the material storage box 2 into the conveying pipeline 4.

[0069] Among them, in step 2), the speed fine-tuning method is the following formula (1):

[0070] (1);

[0071] in, The size of the pulse can be adjusted; An operation for adjusting the size of the pulse;

[0072] For positive and negative pulses, is the width of positive and negative pulses per unit time, To adjust the positive and negative pulse width per unit time;

[0073] In order to control the speed of the feed drive reducer 5 by adjusting the positive and negative pulse widths per unit time and the size of the pulse, It is the speed of the feed drive reducer 5.

[0074] Example 5

[0075] Based on Example 4, Figure 6 As shown in formula (1), within a unit time of 1s, there are positive and negative pulses. When the unit time is shortened or increased, the widths of the positive and negative pulses are shortened or increased at the same time. For example, when the unit time is shortened from 1s to 0.5s, the widths of the positive and negative pulses are shortened at the same time. When the unit time is increased from 0.5s to 1s, the widths of the positive and negative pulses are increased at the same time. The size of the positive and negative pulses can be adjusted because the size of the positive and negative pulses is adjusted at the same time. For example, when the positive pulse increases from 3A to 2A, the negative pulse increases from -3A to -2A, and when the positive pulse increases from 2A to 3A, the negative pulse increases from -2A to -3A.

[0076] Since the feed drive reducer 5 is powered by alternating current, the controller controls the rotation speed of the feed drive reducer 5 by adjusting the size and width of the positive and negative pulses.

[0077] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
