[0021] The present invention delivers raw materials into a material holding part through a feeding part. When the weight of the raw materials in the material holding part reaches a target weight, a lifting unit drives the material holding unit to descend as a whole, so that the material holding part enters the box body of a cooking unit. When the material holding part is completely accommodated in the box body, the material holding part is immersed in the clean water in the box body. At this time, all the raw materials are immersed in the water, thereby solving the technical problems in the prior art that the dry peppers float on the water surface, resulting in different water absorption efficiencies and uneven rehydration degrees.

[0022] Furthermore, the box body includes an inner layer and an outer layer, wherein the outer layer is wrapped around the outer side of the inner layer, and a closed interlayer is formed between the outer layer and the inner side, and an ultrasonic generator fixed to the inner bottom is arranged in the interlayer.

[0023] Ultrasonic waves are applied during the cooking process to further improve the water absorption efficiency, accelerate the temperature rise of the medium, and shorten the cooking time; after the cooking is completed, ultrasonic waves can also be used to clean the box.

[0024] Furthermore, a vacuum layer is provided inside the outer layer to wrap the outer side of the interlayer.

[0025] Ultrasonic waves are isolated by the vacuum layer to prevent them from causing harm to the human body.

[0026] Furthermore, the material receiving part includes a drum, the drum is rotatably connected to the end cover, and blades are fixed in the drum and arranged parallel to the axis of the drum and protruding in the radial direction of the drum;

[0027] The material holding unit further comprises a first power device, through which the roller is driven to rotate along its own circumferential direction.

The bottom of the first sealing plate cooperates with the U-shaped groove, the sealing protrusion cooperates with the sealing groove, and the surface of the first sealing plate close to the discharge port contacts the groove wall of the U-shaped groove and the outer surface of the sealing block, thereby improving the sealing between the first sealing plate and the discharge port.

[0036] Furthermore, the lifting unit comprises:

[0037] Fourth power unit;

[0038] A connecting frame is connected to the material holding unit and is driven to slide vertically by a fourth power device.

[0039] Furthermore, the lifting unit also includes:

The first limiting column is arranged near the material discharge port, and the second limiting column is arranged near the material feed port. The length of the first limiting column is greater than that of the second limiting column.

[0042] After the rehydration is completed, the fourth power device drives the slide to move upward. When one side of the top of the material holding unit contacts the first limit column, the side in contact with the first limit column stops moving, and the fourth power device continues to drive the slide to move upward. At this time, the connecting frame and the slide rotate relative to each other, so that the material holding unit is tilted as a whole to facilitate the discharge of the raw materials from the discharge port.

[0056] The second sealing part closes the feed port so that the feed part stops feeding the raw material into the material holding part;

[0057] The lifting unit drives the material holding unit to descend as a whole, so that the material holding part enters the box body of the cooking unit. When the material holding part is completely accommodated in the box body, the material holding part is submerged in the clean water in the box body.

[0058] When the material holding part is completely accommodated in the box body, the control unit starts timing, and when the timing reaches a first preset time, the control unit controls the lifting unit to lift the material holding unit out of the box body;

[0059] Based on the water conservation target judgment result, the lifting unit and the material holding unit are controlled to perform actions, including:

[0060] When the calculated result of the water retention rate is less than the preset range of the water retention rate, the lifting unit is controlled to drive the material holding part to descend and enter the box to continue cooking for a second preset time;

[0061] When the calculated result of the water retention rate falls within the preset range of the water retention rate, the first sealing plate is opened.

[0062] The present invention has the following advantages:

[0063] The present invention delivers raw materials into a material holding part through a feeding part. When the weight of the raw materials in the material holding part reaches a target weight, a lifting unit drives the material holding unit to descend as a whole, so that the material holding part enters the box body of a cooking unit. When the material holding part is completely accommodated in the box body, the material holding part is immersed in the clean water in the box body.

DETAILED DESCRIPTION

[0090] The embodiments of the present application are described in detail below. As described in the background technology, the existing dry pepper rehydration equipment usually contains a certain volume of clean water in a container, heats the clean water to a certain temperature through the heating device of the equipment itself, and then transports the dry pepper to the container manually or by a conveying device, and quickly rehydrates the dry pepper by soaking or boiling. However, the above technical solution has the following problems: due to the light weight of the dry pepper, when it is poured into the water, it will float on the water surface, resulting in the upper layer of dry peppers and the lower layer of dry peppers having different water retention rates within a preset time, resulting in uneven rehydration of the same batch of dry peppers.

[0091] Embodiment 1:

[0092] Therefore, in order to solve the above technical problems of the prior art, this embodiment provides a raw material rehydration system, such as Figure 2 As shown, the rehydration system includes a cooking unit 400, a material holding unit 500 and a lifting unit 600. The material holding unit is connected to the lifting unit, and the lifting unit drives the material holding unit to move vertically so that the material holding unit enters and exits the cooking unit.

[0095] A heater 420, which is installed at the bottom of the box 410;

[0096] like Figures 5 to 7 As shown, the material holding unit comprises:

[0097] The material holding part 520 contains a limited amount of raw materials. The surface of the material holding part is provided with mesh holes. When the material holding unit completely enters the cooking unit, the material holding part is submerged by the limited amount of clean water contained in the box body 410. End covers 550 are provided at both ends of the material holding part. The end covers form a seal with the material holding part. A feed inlet is provided at the upper part of the end cover at one end, and a discharge outlet is provided at the lower part of the end cover at the other end.

[0098] A feeding part 540, which is connected to the feeding port, and through which the temporarily stored raw materials are fed into the material holding part;

[0099] The first sealing portion 570, such as Fig. 9 As shown, the first sealing part includes a first sealing plate 571, which is movably arranged at the discharge port, and the discharge port is opened and closed by the movement of the first sealing plate;

[0100] The second sealing portion 580, such as Figure 8 As shown, the second sealing part includes a second sealing plate 581, which is arranged at the connection between the feeding part and the feeding port, and the opening and closing of the feeding port is realized by the movement of the second sealing plate;

[0101] In this embodiment, if Figure 1 As shown, the rehydration system also includes:

[0102] The sensing unit 100 includes a weight sensor, through which the weight data of the material holding part is obtained;

[0103] A control unit 200, which is connected to the sensing unit, the cooking unit, the material holding unit and the lifting unit;

[0104] like Fig.19 As shown, the control unit includes:

[0105] A data collection module 210 collects weight data;

[0106] The rehydration control module 260 obtains the weight data before rehydration, determines the target weight according to the weight data before rehydration, obtains the target weight determination result, and controls the lifting unit and the material holding unit to perform the rehydration action according to the target weight determination result;

[0107] A data determination module 260, which obtains the rehydrated weight data, performs weight change calculation based on the rehydrated weight data to obtain a weight change calculation result, performs data stability judgment based on the weight change calculation result to obtain a data stability judgment result, and then determines the rehydrated weight data based on the data stability judgment result;

[0108] The water retention rate calculation module 220 calculates the water retention rate according to the weight data before rehydration and the determined weight data after rehydration, obtains the water retention rate calculation result, and makes a water retention target judgment based on the water retention rate calculation result, so that the rehydration control module controls the lifting unit and the material holding unit to perform actions based on the water retention target judgment result.

[0109] The working principle of this embodiment is as follows:

[0110] Pour the dried chilies into the feeding part for temporary storage in advance, and inject a certain volume of clean water into the box, start the rehydration system, and the rehydration control module controls the heater to heat the clean water to boil the clean water, open the second sealing plate to connect the feeding part with the material holding part, and the feeding part sends the raw materials into the material holding part. The weight sensor obtains the weight data before rehydration and uploads it to the control unit;

[0111] The data acquisition module in the control unit collects the weight data before rehydration, determines the target weight according to the weight data before rehydration, obtains the target weight determination result, and controls the lifting unit and the material holding unit to perform the rehydration action according to the target weight determination result;

[0112] After the rehydration is completed, the lifting unit drives the material holding unit to rise. At the same time, the control unit obtains the weight data after the rehydration, performs weight change calculation according to the weight data after the rehydration, obtains the weight change calculation result, performs data stability judgment based on the weight change calculation result, obtains the data stability judgment result, and then determines the weight data after the rehydration according to the data stability judgment result;

[0113] Calculate the water retention rate according to the weight data before rehydration and the determined weight data after rehydration to obtain the water retention rate calculation result, and make a water retention target judgment based on the water retention rate calculation result, so that the rehydration control module controls the lifting unit and the material holding unit to perform actions based on the water retention target judgment result;

[0114] In this embodiment, the weight before rehydration is the weight of the material holding part before the raw materials in the material holding part are steamed, and the weight after rehydration is the weight of the material holding part after the raw materials in the material holding part are steamed.

[0115] In this embodiment, the weight change is calculated as follows:

[0116] Δm=m t -m t-a ;

[0117] Wherein, Δm is the calculated weight change of the raw material after rehydration, in kg; m t The weight data collected at the current time t after the raw material is rehydrated, in kg; m t-a It is the weight data collected at the previous time ta after the raw material is rehydrated, in kg.

[0118] The weight change calculation result is obtained by the above calculation method, and the data stability is judged according to the weight change calculation result. The specific judgment method is as follows:

[0119] Δm <A;

[0120] Wherein, A is the preset stable target weight change data, in kg.

[0121] If it is greater than A, it means that there is still a lot of water in the material holding part that has not been drained out, and it is necessary to wait for the water in the material holding part to continue to drain out;

[0122] If it is less than A, it means that the water in the material holding part has been drained out. At this time, the weight data obtained is the actual weight of the material holding part after the raw material is rehydrated, that is, the determined weight data after rehydration;

[0123] The weight data after rehydration is obtained by the above method, and the water retention rate is calculated according to the weight data before rehydration. The specific calculation method is as follows:

[0124]

[0125] Wherein, B is water retention rate; m t1 The weight after rehydration is determined in kg; m k It is the weight data before rehydration, in kg.

[0126] The calculation result of the water retention rate is obtained by the above calculation method, and the calculated water retention rate is compared with the preset minimum water retention rate;

[0127] When the calculated result of the water retention rate is less than the preset range of the water retention rate, the lifting unit is controlled to drive the material holding part to descend and enter the box to continue cooking for a second preset time;

[0128] When the calculated result of the water retention rate falls within the preset range of the water retention rate, the first sealing plate is opened.

[0129] In this embodiment, the rehydration action includes:

[0130] The second sealing part closes the feed port so that the feed part stops feeding the raw material into the material holding part;

[0131] The lifting unit drives the material holding unit to descend as a whole, so that the material holding part enters the box body of the cooking unit. When the material holding part is completely accommodated in the box body, the material holding part is submerged in the clean water in the box body.

[0132] When the material holding part is completely accommodated in the box body, the control unit starts timing, and when the timing reaches a first preset time, the control unit controls the lifting unit to lift the material holding unit out of the box body;

[0133] The present invention delivers raw materials into a material holding part through a feeding part. When the weight of the raw materials in the material holding part reaches a target weight, a lifting unit drives the material holding unit to descend as a whole, so that the material holding part enters the box body of a cooking unit. When the material holding part is completely accommodated in the box body, the material holding part is immersed in the clean water in the box body. At this time, all the raw materials are immersed in the water, thereby solving the technical problems in the prior art that the dry peppers float on the water surface, resulting in different water absorption efficiencies and uneven rehydration degrees. At the same time, the present invention automatically controls the entire rehydration system through a control unit, thereby realizing the automation of raw material rehydration, reducing labor intensity, and improving the automation and standardization of raw material processing.

[0134] In this embodiment, if Figure 6 As shown, the material holding unit may also include a fixing frame 530, and the material holding part, the first sealing part, the second sealing part and the feeding part are all installed on the fixing frame 530. A box cover 510 wrapped around the outside of the fixing frame is also fixed on the fixing frame. When the material holding part completely enters the box body, the box cover is sealed on the top of the box body, and an air outlet is opened on the side of the box cover.

[0135] In this embodiment, if Figure 6 As shown, the feed part includes a feed hopper 541, which is fixed on a fixed frame, and the bottom of the feed hopper is inclined and connected to the feed port, and the top passes through the box cover and extends to above the box cover. A vibration device 542 is provided on the side of the feed hopper, and the feed hopper is driven to shake by the vibration device to accelerate the flow of raw materials to the material holding part.

[0136] In this embodiment, the material holding portion may be cylindrical or cubical.

[0137] In this embodiment, the first and second sealing plates can be opened manually, and the staff can judge the opening and closing timing of the sealing plates according to the data displayed on the display, thereby opening or closing the sealing plates.

[0138] In this embodiment, the preset time is determined by:

[0139] The data table of water retention rate range corresponding to cooking time is input into the rehydration control module, and the rehydration control module matches the calculated water retention rate with the water retention rate range in the data table to obtain a matching result, and controls the re-cooking time according to the matching result. The above data table can be obtained through a limited number of times.

[0140] Embodiment 2:

[0141] To improve the water absorption efficiency of dried peppers, Figure 4As shown, the box body in this embodiment may include an inner layer 411 and an outer layer 412, wherein the outer layer is wrapped around the outer side of the inner layer to form a closed interlayer between the outer layer and the inner side, and an ultrasonic generator 430 fixed to the inner bottom is provided in the interlayer.

[0142] By applying ultrasound during the cooking process, the water absorption efficiency can be further improved, the medium temperature can be accelerated, and the cooking time can be shortened; after the cooking is completed, the ultrasound can also be used to clean the box.

[0143] In this embodiment, a vacuum layer is provided inside the outer layer to wrap the outer side of the interlayer.

[0144] A vacuum layer is arranged inside the inner wall of the box cover.

[0145] Ultrasonic waves are isolated by the vacuum layer, thereby reducing the transmission of ultrasonic waves to the outside and avoiding harm to the human body.

[0146] Embodiment 3:

[0147] In order to improve the cooking efficiency of raw materials and improve the uniformity of raw material rehydration, Fig.12 As shown, the material receiving portion 520 in this embodiment includes a roller 521, which is rotatably connected to the end cover, and a blade 522 is fixed in the roller 521 and is arranged parallel to the axis direction of the roller and protrudes along the radial direction of the roller;

[0148] like Figure 7 As shown, the material holding unit further includes a first power device 560, through which the roller 521 is driven to rotate along its own circumferential direction.

[0149] The first power device can be fixedly mounted on a fixed frame and maintained in connection with the drum via a third pulley mechanism.

[0169] Embodiment 5:

[0170] like Fig.15 As shown, the lifting unit includes:

[0171] Stand 610;

[0172] A fourth power device 660, which is mounted on the top of the stand;

[0173] A connecting frame 630 is connected to the material holding unit and is driven to slide vertically by a fourth power device.

[0174] like Fig.17 As shown, the lifting unit may also include:

[0175] The slide 680 is driven by the fourth power device to slide vertically as a whole, and the slide is rotationally connected with the connecting frame;

[0176] The top frame 620 is integrally arranged above the material holding unit and is fixedly connected to the top of the vertical frame. Fig.18 The top frame shown includes a first limiting column 621 and a second limiting column 622, wherein the first limiting column is arranged close to the discharge port, and the second limiting column is arranged close to the feed port, and the length of the first limiting column is greater than that of the second limiting column.

[0177] After the rehydration is completed, the fourth power device drives the slide to move upward. When one side of the top of the material holding unit contacts the first limit column, the side in contact with the first limit column stops moving, and the fourth power device continues to drive the slide to move upward. At this time, the connecting frame and the slide rotate relative to each other, so that the material holding unit is tilted as a whole to facilitate the discharge of the raw materials from the discharge port.

[0178] In this embodiment, if Fig.17 As shown. The above-mentioned connecting frame can be connected to the slide in rotation through a rotating connecting member 650. The rotating connecting member can be a mechanism in the prior art that can realize the relative rotation of the two parts, such as a rotating connecting shaft, a rotating connecting bearing, etc. The above-mentioned fourth power device includes but is not limited to a servo motor, a stepping motor, a rotating cylinder, etc., which can realize power output.

The above-mentioned slide and counterweight can be slidably connected to the stand through a guide structure to avoid shaking during the lifting process.

[0180] In this embodiment, the sensor unit 100 further includes

[0181] A pressure sensor is installed at the end of the first limit column to obtain a pressure signal of the material holding unit on the first limit column;

[0182] A displacement sensor is used to obtain the rising height data of the material holding unit;

[0183] like Fig.19 As shown, the control unit also includes:

[0184] A travel determination module 230 determines an initial value of the ascending height data according to the pressure signal;

[0185] The slope calculation module 240 calculates the inclination angle of the material holding unit according to the rising height data and the initial value of the height data, so that the rehydration control module controls the lifting unit to perform actions based on the calculation result of the inclination angle.

[0186] When the calculated result of the water retention rate falls within the preset range of the water retention rate, the fourth power device drives the slide to continue to rise. When one side of the upper surface of the material holding unit contacts the pressure sensor, the pressure sensor generates a pressure signal. The data acquisition module of the control unit obtains the pressure signal and the current height data, and uploads the pressure signal to the stroke judgment module. The stroke judgment module sets the current height data as the initial height according to the pressure signal. The fourth power device continues to drive the slide to rise. Since one side of the material holding unit is restricted by the first limit column and cannot continue to move upward, while the other side is not restricted, the unrestricted side of the connecting frame will continue to move upward under the drive of the slide, and at the same time begin to rotate along the circumference of the rotating connecting piece. During this process, the slope calculation module will calculate the inclination angle of the material holding unit according to the rising height data and the initial value of the above-mentioned height data. The calculation method is as follows;

[0187]

[0188] Among them, θ is the inclination angle of the material holding unit, Δh is the difference between the current height of the material holding unit and the height when it contacts the first limit column, in m; l is the distance from the rotation center to the side of the material holding unit where the discharge port is located, in m.

[0189] Among them, Δh is calculated as:

[0190] Δh=h-h0;

[0191] Among them, h is the current height data, the unit is m; h0 is the initial value of the height data, the unit is m.

[0192] The tilt angle of the material holding unit is calculated by the above calculation method, and the calculated tilt angle is compared with the preset tilt angle. When the tilt angle is equal to the preset tilt angle, the lifting unit stops running and the second sealing part opens the discharge port.

[0193] The control unit controls the travel of the slide, thereby realizing the control of the tilt angle of the material holding unit.

[0194] Embodiment 6:

[0195] Based on the rehydration system provided in the above embodiment, this embodiment provides a raw material rehydration method, which uses the above rehydration system, and the rehydration method includes:

[0196] Pour the dried chilies into the feeding part for temporary storage in advance, and inject a certain volume of clean water into the box, start the rehydration system, and the rehydration control module controls the heater to heat the clean water to boil the clean water, open the second sealing plate to connect the feeding part with the material holding part, and the feeding part sends the raw materials into the material holding part. The weight sensor obtains the weight data before rehydration and uploads it to the control unit;

[0197] The data acquisition module in the control unit collects the weight data before rehydration, determines the target weight according to the weight data before rehydration, obtains the target weight determination result, and controls the lifting unit and the material holding unit to perform the rehydration action according to the target weight determination result;

[0198] After the rehydration is completed, the lifting unit drives the material holding unit to rise. At the same time, the control unit obtains the weight data after the rehydration, performs weight change calculation according to the weight data after the rehydration, obtains the weight change calculation result, performs data stability judgment based on the weight change calculation result, obtains the data stability judgment result, and then determines the weight data after the rehydration according to the data stability judgment result;

[0199] Calculate the water retention rate according to the weight data before rehydration and the determined weight data after rehydration to obtain the water retention rate calculation result, and make a water retention target judgment based on the water retention rate calculation result, so that the rehydration control module controls the lifting unit and the material holding unit to perform actions based on the water retention target judgment result;

[0200] In this embodiment, the weight before rehydration is the weight of the material holding part before the raw materials in the material holding part are steamed, and the weight after rehydration is the weight of the material holding part after the raw materials in the material holding part are steamed.

[0201] Specifically, the weight change is calculated as follows:

[0202] Δm=m t -m t-a ;

[0203] Wherein, Δm is the calculated weight change of the raw material after rehydration, in kg; m t The weight data collected at the current time t after the raw material is rehydrated, in kg; m t-a It is the weight data collected at the previous time ta after the raw material is rehydrated, in kg.

[0204] The weight change calculation result is obtained by the above calculation method, and the data stability is judged according to the weight change calculation result. The specific judgment method is as follows:

[0205] Δm <A;

[0206] Wherein, A is the preset stable target weight change data, in kg.

[0207] If it is greater than A, it means that there is still a lot of water in the material holding part that has not been drained out, and it is necessary to wait for the water in the material holding part to continue to drain out;

[0208] If it is less than A, it means that the water in the material holding part has been drained out. At this time, the weight data obtained is the actual weight of the material holding part after the raw material is rehydrated, that is, the determined weight data after rehydration;

[0209] The weight data after rehydration is obtained by the above method, and the water retention rate is calculated according to the weight data before rehydration. The specific calculation method is as follows:

[0210]

[0211] Wherein, B is water retention rate; m t1 The weight after rehydration is determined in kg; m k It is the weight data before rehydration, in kg.

[0212] The calculation result of the water retention rate is obtained by the above calculation method, and the calculated water retention rate is compared with the preset minimum water retention rate;

[0213] When the calculated result of the water retention rate is less than the preset range of the water retention rate, the lifting unit is controlled to drive the material holding part to descend and enter the box to continue cooking for a second preset time;

[0214] In this embodiment, the rehydration action includes:

[0215] The second sealing part closes the feed port so that the feed part stops feeding the raw material into the material holding part;

[0216] The lifting unit drives the material holding unit to descend as a whole, so that the material holding part enters the box body of the cooking unit. When the material holding part is completely accommodated in the box body, the material holding part is submerged in the clean water in the box body.

[0217] When the material holding part is completely accommodated in the box body, the rehydration control module controls the first power device to drive the drum to rotate and starts timing at the same time. When the timing reaches the first preset time, the control unit controls the lifting unit to lift the material holding unit out of the box body.

[0218] When the calculated result of the water retention rate falls within the preset range of the water retention rate, the fourth power device drives the slide to continue to rise. When one side of the upper surface of the material holding unit contacts the pressure sensor, the pressure sensor generates a pressure signal. The data acquisition module of the control unit obtains the pressure signal and the current height data, and uploads the pressure signal to the stroke judgment module. The stroke judgment module sets the current height data as the initial height according to the pressure signal. The fourth power device continues to drive the slide to rise. Since one side of the material holding unit is restricted by the first limit column and cannot continue to move upward, while the other side is not restricted, the unrestricted side of the connecting frame will continue to move upward under the drive of the slide, and at the same time begin to rotate along the circumference of the rotating connecting piece. During this process, the slope calculation module will calculate the inclination angle of the material holding unit according to the rising height data and the initial value of the above-mentioned height data. The calculation method is as follows;

[0219]

[0220] Among them, θ is the inclination angle of the material holding unit, Δh is the difference between the current height of the material holding unit and the height when it contacts the first limit column, in m; l is the distance from the rotation center to the side of the material holding unit where the discharge port is located, in m.

[0221] Among them, Δh is calculated as:

[0222] Δh=h-h0;

[0223] Among them, h is the current height data, the unit is m; h0 is the initial value of the height data, the unit is m.

[0224] The tilt angle of the material holding unit is calculated by the above calculation method, and the calculated tilt angle is compared with the preset tilt angle. When the tilt angle is equal to the preset tilt angle, the lifting unit stops running and the second sealing part opens the discharge port.
