Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable crisp processing, and more particularly to an equipment and method for processing fruit and vegetable crisps. Background Technology

[0002] Fruit and vegetable crisps are a popular snack among consumers. Their production process typically includes steps such as ingredient selection, cleaning, blanching, quick freezing, vacuum frying, and dehydration.

[0003] In the existing fruit and vegetable crisp production process, there is still room for improvement in the processing steps after blanching and before quick-freezing. Often, the original taste and flavor components of the fruits and vegetables cannot be preserved, and the appearance shrinks to some extent. Currently, there is a lack of an effective method to allow starch and syrup to fully penetrate into the fruits and vegetables to improve the appearance, taste, and quality of the fruit and vegetable crisps. At the same time, there is no equipment specifically designed for this process, resulting in poor processing results in this step and affecting the quality of the final product. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device and method for processing fruit and vegetable crisps.

[0005] In a first aspect, the present invention provides a fruit and vegetable crisping processing device, comprising a sealed processing box, and further comprising:

[0006] A sealing cap is detachably and securely fixed to the top of the sealing processing box;

[0007] The feed inlet is connected to and fixed to the top of the sealing cover;

[0008] An exhaust port is connected to the top of the sealing cover;

[0009] A discharge port is connected to and fixed to the bottom of the sealed processing box, and a first control valve is installed inside the discharge port;

[0010] A pressure regulation component is used to monitor and adjust the pressure inside the sealed processing chamber;

[0011] A temperature control component is used to monitor and adjust the temperature inside the sealed processing chamber;

[0012] A liquid circulation assembly is installed at the bottom of the sealed processing box to drive the circulation of the mixed liquid inside the sealed processing box;

[0013] Fruit and vegetable slices are added to the inside of a sealed processing chamber, which is then sealed and closed. A mixture of starch and syrup is added to the inside of the sealed processing chamber through the inlet. The pressure control component adjusts the pressure inside the sealed processing chamber to a suitable level, while the liquid circulation component is activated to drive the mixture to flow. The temperature control component adjusts the mixture to a suitable level, allowing it to circulate at a specified temperature under the adjusted pressure environment. As the mixture flows over the fruit and vegetable slices, the starch and syrup fully penetrate the fruit and vegetable slices under pressure, enhancing the texture and flavor of the fruit and vegetable crisps and improving product quality.

[0014] Preferably, the pressure regulating component includes:

[0015] An air pump is fixed to the top of the sealing cover;

[0016] The first connecting pipe is fixedly connected to the input end of the air pump;

[0017] An input tube is fixedly connected between the middle of the first connecting tube and the sealing cap;

[0018] The second connecting pipe is fixedly connected to the output end of the air pump;

[0019] The output tube is fixedly connected between the middle of the second connecting tube and the sealing cap;

[0020] Four second control valves are respectively fixedly installed inside the first connecting pipe, the input pipe, the second connecting pipe, and the output pipe;

[0021] A pressure sensor is installed at the bottom of the sealing cover;

[0022] Only the second control valve inside the input pipe and the second connecting pipe is opened, and then the air pump is started, so that the air pump inputs gas into the sealing processing box, thereby pressurizing the inside of the sealing processing box. When only the second control valve inside the output pipe and the first connecting pipe is opened, the air pump is then started, so that the air pump extracts the gas from the inside of the sealing processing box, so that the inside of the sealing processing box is in a negative pressure state, thereby enabling pressure regulation inside the sealing processing box. The pressure sensor can detect the pressure of the sealing processing box.

[0023] Preferably, it further includes:

[0024] A connecting bracket is fixed to the top of the inner wall of the sealing cover;

[0025] The top frame is fixed to the bottom of the connecting frame;

[0026] Multiple intermediate frames are arranged in a vertical array, with the top intermediate frame installed at the bottom of the top frame;

[0027] The bottom frame is installed at the bottom of the middle frame at the very bottom;

[0028] Two cylinders are symmetrically fixed to the outer wall of the sealing processing box, and the sealing cover is moved vertically to open via a telescopic rod;

[0029] The bottom frame and the top of all the middle frames are provided with multiple partition plates arranged coaxially.

[0030] The top frame, middle frame, and bottom frame can be spliced ​​and assembled to form a movable wire mesh frame. Multiple partitions are set inside the bottom frame and middle frame. Both the movable wire mesh frame and the partitions are mesh structures that allow liquid to pass through, so that the mixed liquid can pass through freely. This allows the fruit and vegetable slices to be distributed inside the movable wire mesh frame of each layer to disperse the fruit and vegetable slices and prevent them from piling up together, which would prevent the mixed liquid from fully contacting the fruit and vegetable slices and thus affect the processing effect of the fruit and vegetable slices.

[0031] After the cylinder is started, it can drive the sealing cover to move vertically, which in turn drives the movable mesh frame to move vertically, so that the movable mesh frame moves upward and moves out of the sealed processing box. Then, the staff can load and unload the fruit and vegetable slices.

[0032] Preferably, it further includes:

[0033] Multiple first threaded ends are respectively fixed to the top of each of the intermediate frames and the top of each of the bottom frames;

[0034] Multiple second threaded ends are respectively fixed to the bottom of the top frame and the bottom of each of the middle frames, and the second threaded ends are threadedly matched with the first threaded ends;

[0035] The threaded connection between the first and second threaded ends allows the top frame to be threadedly connected to the middle frame, adjacent middle frames to be threadedly connected, and the middle frame to the bottom frame to be threadedly connected. This threaded connection allows adjustment of the distances between the top and middle frames, adjacent middle frames, and the middle and bottom frames. For fruit and vegetable slices of different thicknesses, the distances can be adjusted to be greater than the thickness of the fruit and vegetable slices but less than their width. This ensures that the fruit and vegetable slices only move under the flow of the mixed liquid, without tumbling or piling up. Furthermore, the coaxial arrangement of multiple rings of fruit and vegetable slices, separated by partitions, prevents them from piling up in the corners of the movable frame under the flow of the mixed liquid, thus avoiding the accumulation of fruit and vegetable slices.

[0036] Preferably, the liquid circulation assembly includes:

[0037] A circulating pump is fixed to the bottom of the sealed processing box;

[0038] The inlet pipe connects the output end of the circulating pump to the side wall of the sealing processing box;

[0039] The outlet pipe connects the input end of the circulating pump to the side wall of the sealed processing box;

[0040] After the circulation pump starts, it drives the flow of the mixture, causing the mixture to flow along the trajectory of the sealed processing box, the outlet pipe, the circulation pump, the inlet pipe, and finally back into the sealed processing box. This circulation of the mixture helps maintain its uniformity and avoids sedimentation that could affect the processing effect on the fruit and vegetable slices.

[0041] Preferably, the temperature control component includes:

[0042] A temperature control box is fixedly connected between the liquid inlet pipe and the output end of the circulation pump;

[0043] The heater and condenser are both fixed to the top of the temperature control box;

[0044] A partition plate is fixed inside the temperature control box, dividing the interior of the temperature control box into a heating chamber and a cooling chamber;

[0045] Multiple heat pipes are fixed inside the heating chamber and the cooling chamber, respectively, and the heat pipes are connected to the heater and the condenser, respectively.

[0046] The monitoring box is fixedly connected between the outlet pipe and the input end of the circulation pump;

[0047] A temperature monitor is fixed inside the monitoring box;

[0048] The temperature monitor can detect the temperature of the mixture flowing through its interior. When the temperature is lower than the specified temperature, it controls the heater to start, which heats the heat pipe connected to it, thus heating the mixture flowing through the heating chamber. When the temperature is higher than the specified temperature, it controls the condenser to start, which cools the heat pipe connected to it, thus cooling the mixture flowing through the cooling chamber. This allows for the detection and regulation of the mixture's temperature.

[0049] Preferably, it further includes:

[0050] Multiple sets of spiral channels, the spiral channels are arranged in a group and arranged in a circumferential array, and each set of spiral channels is opened at the lower end of the first thread end;

[0051] The first connecting pipe has one end fixedly connected to the side wall of the connecting frame and the other end fixedly connected to the connecting box. When the sealing cover is sealed and connected to the sealing processing box, the connecting box is connected to the liquid inlet pipe.

[0052] The spiral channel is located at the lower end of the first threaded end, so that when the mixture enters the sealed processing box through the inlet pipe, it enters the connecting frame through the connecting box body and the first connecting pipe. Then it flows along the channel formed by the first and second threaded ends after the threaded connection. When flowing through the channel formed by the first and second threaded ends, the mixture flows into each layer of the movable mesh frame along a spiral trajectory under the action of the spiral channel. This makes the mixture flow evenly and spirally into each layer of the movable mesh frame, which is conducive to the mixing and contact of the mixture with the fruit and vegetable slices, thereby improving the processing effect of the fruit and vegetable slices.

[0053] Preferably, it further includes:

[0054] The turbine is installed inside the connecting frame;

[0055] A connecting shaft is coaxially fixed to the bottom of the turbine;

[0056] A baffle plate is fixed to the bottom of the bottom frame;

[0057] The collection box is fixed to the bottom center of the baffle.

[0058] The second connecting pipe is fixed in a circular array between the side wall of the collection box and the edge of the baffle. One end of the second connecting pipe is connected to the interior of the collection box, and the other end passes through the baffle and connects to its top.

[0059] The drive blade is installed inside the collection box;

[0060] Multiple telescopic connecting rods are rotatably installed inside each of the first threaded ends. After the telescopic connecting rods are connected, they rotate synchronously. The topmost telescopic connecting rod rotates synchronously after being connected to the connecting shaft, and the bottommost telescopic connecting rod rotates synchronously after being connected to the drive blade.

[0061] When the mixture flows through the interior of the connecting frame, it drives the turbine to rotate. The turbine drives the connecting shaft to rotate, which in turn drives the telescopic connecting rod to rotate. The telescopic connecting rod drives the drive blade to rotate, which in turn drives the mixture to flow. This causes the mixture to flow along the space above the baffle, through the second connecting pipe, into the interior of the collecting box, and then flow downwards. As a result, the mixture flows out spirally through the spiral channel and then flows downwards through the edge into the interior of the second connecting pipe, forming a flow trajectory for the mixture. This improves the fluidity of the mixture around the fruit and vegetable slices, thereby enhancing the processing effect on the fruit and vegetable slices.

[0062] Secondly, a method for processing fruit and vegetable crisps is provided, the method comprising the following steps:

[0063] Step 1: Fruit and vegetable cleaning: Sort the fruits and vegetables, select the qualified ones and wash them to remove surface impurities;

[0064] Step 2, Fruit and vegetable blanching: Use hot water blanching or steam blanching to heat the fruits and vegetables to a specified temperature and maintain it for an appropriate time to destroy the enzyme activity in the fruits and vegetables;

[0065] Step 3, sealing the seepage: Immediately after blanching, transfer the fruits and vegetables to the fruit and vegetable crisping equipment. Add the pre-prepared mixture of starch and syrup to the equipment, seal and close the equipment, and pressurize the inside of the equipment through the pressure control component system. Keep the pressure within an effective range and maintain it for a certain period of time to allow the starch and syrup to penetrate into the fruits and vegetables under pressure.

[0066] Step 4, quick freezing of fruits and vegetables: After depressurization, remove the permeation-treated fruits and vegetables from the fruit and vegetable crisping equipment and transfer them to the quick-freezing equipment for quick freezing treatment.

[0067] Preferably, step three specifically includes:

[0068] The starch concentration is 35%, the syrup concentration is 30%, and the temperature of the mixture is controlled at 30°C by a temperature control component.

[0069] Compared with the prior art, the present invention has the following beneficial effects:

[0070] By using the method of this invention, fruits and vegetables are subjected to pressure starch and syrup infiltration treatment after blanching and before quick-freezing. This allows the starch and syrup to fully penetrate into the fruits and vegetables, increasing the texture and flavor of the fruit and vegetable crisps and improving product quality.

[0071] The equipment of this invention can precisely control pressure, temperature and liquid circulation, ensuring process stability and consistency, improving production efficiency and product quality, reducing time, lowering production costs and increasing manufacturing efficiency.

[0079] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0080] like Figures 2 to 6 The illustrated equipment for processing fruit and vegetable crisps includes a sealed processing box 1, and further includes:

[0081] The sealing cover 101 is detachably and securely fixed to the top of the sealing processing box 1;

[0082] The feed inlet 102 is connected to and fixed to the top of the sealing cover 101;

[0083] The exhaust port 103 is connected to the top of the sealing cover 101;

[0084] The discharge port 104 is connected to and fixed to the bottom of the sealed processing box 1, and a first control valve is installed inside the discharge port 104;

[0085] A pressure regulation component is used to monitor and adjust the pressure inside the sealing processing chamber 1;

[0086] Temperature control components are used to monitor and adjust the temperature inside the sealed processing chamber 1;

[0087] A liquid circulation assembly is installed at the bottom of the sealing processing box 1 to drive the circulation of the mixed liquid inside the sealing processing box 1;

[0088] In the existing fruit and vegetable crisp production process, there is still room for improvement in the processing steps after blanching and before quick-freezing. Often, the original taste and flavor components of the fruits and vegetables cannot be preserved, and the appearance shrinks to a certain extent. At present, there is a lack of an effective method to allow starch and syrup to fully penetrate into the fruits and vegetables to improve the appearance, taste and quality of the fruit and vegetable crisps. At the same time, there is no equipment specifically for this process, resulting in poor processing effect in this step and affecting the quality of the final product.

[0089] This embodiment of the invention can solve the above problems. The specific implementation method is as follows: Fruit and vegetable slices are added into the interior of the sealed processing box 1, and then the sealed processing box 1 is sealed and closed. A mixture of starch and syrup is added into the interior of the sealed processing box 1 through the feed port 102. The pressure control component is used to adjust the pressure inside the sealed processing box 1 to a suitable level. At the same time, the liquid circulation component is activated to drive the mixture to flow, and the temperature control component is used to adjust the mixture to a suitable level. The mixture circulates at a specified temperature under the adjusted pressure environment. When the mixture flows through the fruit and vegetable slices, under the pressure environment, the starch and syrup fully penetrate into the fruit and vegetable slices, increasing the taste and flavor of the fruit and vegetable crisps and improving the product quality.

[0090] As an optional embodiment, the pressure regulation component includes:

[0091] Air pump 2 is fixed to the top of sealing cover 101;

[0092] The first connecting pipe 201 is fixedly connected to the input end of the air pump 2;

[0093] The input pipe 202 is fixedly connected between the middle part of the first connecting pipe 201 and the sealing cover 101;

[0094] The second connecting pipe 203 is fixedly connected to the output end of the air pump 2;

[0095] The output tube 204 is fixedly connected between the middle part of the second connecting tube 203 and the sealing cover 101;

[0096] Four second control valves are respectively fixedly installed inside the first connecting pipe 201, the input pipe 202, the second connecting pipe 203, and the output pipe 204;

[0097] A pressure sensor is installed at the bottom of the sealing cover 101;

[0098] Only the second control valve inside the input pipe 202 and the second connecting pipe 203 is opened, and then the air pump 2 is started, so that the air pump 2 inputs gas into the sealing processing box 1, thereby pressurizing the inside of the sealing processing box 1. When only the second control valve inside the output pipe 204 and the first connecting pipe 201 is opened, the air pump 2 is then started, so that the air pump 2 extracts the gas from the inside of the sealing processing box 1, so that the inside of the sealing processing box 1 is in a negative pressure state, thereby enabling pressure regulation inside the sealing processing box 1. The pressure sensor can detect the pressure of the sealing processing box 1.

[0099] As an optional embodiment, it also includes:

[0100] The connecting bracket 304 is fixed to the top of the inner wall of the sealing cover 101;

[0101] The top frame 301 is fixed to the bottom of the connecting bracket 304;

[0102] Multiple intermediate frames 302 are arranged in a vertical array, with the top intermediate frame 302 installed at the bottom of the top frame 301;

[0103] Bottom frame 303 is installed at the bottom of the bottom middle frame 302;

[0104] Two cylinders 305 are symmetrically fixed on the outer wall of the sealing processing box 1, and the sealing cover 101 is moved vertically to open by means of a telescopic rod;

[0105] The bottom frame 303 and the top of all the middle frames 302 are provided with multiple partition plates arranged coaxially;

[0106] The top frame 301, middle frame 302, and bottom frame 303 can be spliced ​​and assembled to form a movable wire mesh frame. Multiple partitions are provided inside the bottom frame 303 and the middle frame 302. Both the movable wire mesh frame and the partitions are mesh structures that allow liquid to pass through, so that the mixed liquid can pass through freely. This allows the fruit and vegetable slices to be distributed inside the movable wire mesh frame of each layer to disperse the fruit and vegetable slices and prevent them from piling up together, which would prevent the mixed liquid from fully contacting the fruit and vegetable slices and thus affect the processing effect of the fruit and vegetable slices.

[0107] After the cylinder 305 is started, it can drive the sealing cover 101 to move vertically, thereby driving the movable mesh frame to move vertically, so that the movable mesh frame moves upward and moves out of the sealed processing box 1, and then the staff can load and unload the fruit and vegetable slices.

[0108] As an optional embodiment, it also includes:

[0109] Multiple first threaded ends 401 are respectively fixed to the top of each intermediate frame 302 and the top of the bottom frame 303;

[0110] Multiple second threaded ends 402 are respectively fixed to the bottom of the top frame 301 and the bottom of each intermediate frame 302, and the second threaded ends 402 are threadedly matched with the first threaded ends 401.

[0111] The threaded connection between the first threaded end 401 and the second threaded end 402 allows the top frame 301 to be threadedly connected to the middle frame 302, adjacent middle frames 302 to be threadedly connected, and the middle frame 302 to be threadedly connected to the bottom frame 303. Through this threaded connection, the distances between the top frame 301 and the middle frame 302, between adjacent middle frames 302, and between the middle frame 302 and the bottom frame 303 can be adjusted. This allows for adjustments to the distances between the top frame 301 and the middle frame 302, between adjacent middle frames 302, and between the middle frame 302 and the bottom frame 303 for fruit and vegetable slices of different thicknesses. The distance of 303 is adjusted to different degrees, so that the distance is greater than the thickness of the fruit and vegetable slices but less than the width of the fruit and vegetable slices. This ensures that when the fruit and vegetable slices are between the top frame 301 and the middle frame 302, between adjacent middle frames 302, and between the middle frame 302 and the bottom frame 303, they will only move under the action of the mixed liquid, but will not be turned over and cause accumulation. In addition, the fruit and vegetable slices are placed in multiple rings on the same axis, and the multiple rings of fruit and vegetable slices are separated from each other by partitions. This prevents the fruit and vegetable slices from accumulating in the corners of the movable wire rack under the action of the mixed liquid, thus helping to avoid the accumulation of fruit and vegetable slices.

[0112] As an optional embodiment, the liquid circulation assembly includes:

[0113] The circulating pump 5 is fixed to the bottom of the sealed processing box 1;

[0114] The inlet pipe 501 is connected between the output end of the circulating pump 5 and the side wall of the sealing processing box 1;

[0115] The outlet pipe 502 is connected between the input end of the circulating pump 5 and the side wall of the sealing processing box 1;

[0116] After the circulation pump 5 starts, it drives the flow of the mixture, so that the mixture flows along the trajectory of the sealed processing box 1, the outlet pipe 502, the circulation pump 5, the inlet pipe 501 and finally back into the sealed processing box 1. This drives the mixture to circulate, thereby maintaining the uniformity of the mixture and helping to avoid the situation where the mixture settles and affects the processing effect on the fruit and vegetable slices.

[0117] As an optional embodiment, the temperature control component includes:

[0118] Temperature control box 6 is fixedly connected between liquid inlet pipe 501 and output end of circulation pump 5;

[0119] The heater 601 and the condenser 602 are both fixed to the top of the temperature control box 6;

[0120] The partition plate 603 is fixed inside the temperature control box 6, dividing the interior of the temperature control box 6 into a heating chamber and a cooling chamber;

[0121] Multiple heat pipes 604 are fixed inside the heating chamber and the cooling chamber, respectively, and the heat pipes 604 are connected to the heater 601 and the condenser 602, respectively.

[0122] The monitoring box 605 is fixedly connected between the outlet pipe 502 and the input end of the circulating pump 5;

[0123] Temperature monitor 606 is fixed inside monitoring box 605;

[0124] The temperature monitor 606 can detect the temperature of the mixture flowing through its interior. When the temperature is lower than the specified temperature, it controls the heater 601 to start, which heats the heat pipe 604 connected to it, thus heating the mixture flowing through the heating chamber. When the temperature is higher than the specified temperature, it controls the condenser 602 to start, which cools the heat pipe 604 connected to it, thus cooling the mixture flowing through the cooling chamber. This allows for the detection and regulation of the mixture's temperature.

[0125] As an optional embodiment, it also includes:

[0126] Multiple sets of spiral channels 7 are arranged in a circular array, and each set of spiral channels 7 is opened at the lower end of the first thread end 401.

[0127] The first connecting pipe 801 has one end fixedly connected to the side wall of the connecting frame 304, and the other end fixedly connected to the connecting box 802. When the sealing cover 101 is sealed and connected to the sealing processing box 1, the connecting box 802 is connected to the liquid inlet pipe 501.

[0128] The spiral channel 7 is located at the lower end of the first threaded end 401, so that when the mixture enters the sealed processing box 1 along the inlet pipe 501, it enters the connecting frame 304 through the connecting box body 802 and the first connecting pipe 801. Then it flows along the channel formed by the first threaded end 401 and the second threaded end 402 after the threaded connection. When flowing through the channel formed by the first threaded end 401 and the second threaded end 402, the mixture flows into each layer inside the movable mesh frame along a spiral trajectory under the action of the spiral channel 7, so that the mixture flows into each layer inside the movable mesh frame in a uniform and spiral manner, which is conducive to the mixing and contact of the mixture with the fruit and vegetable slices, thereby improving the processing effect of the fruit and vegetable slices.

[0129] As an optional embodiment, it also includes:

[0130] Turbine 8 is installed inside the connecting bracket 304;

[0131] The connecting shaft 803 is coaxially fixed to the bottom of the turbine 8;

[0132] Baffle 806 is fixed to the bottom of bottom frame 303;

[0133] The collection box 805 is fixed to the bottom center of the baffle 806;

[0134] The second connecting pipe 807 is fixed in a circular array between the side wall of the converging box 805 and the edge of the baffle 806. One end of the second connecting pipe 807 is connected to the interior of the converging box 805, and the other end passes through the baffle 806 and is connected to its top.

[0135] Drive blade 804 is installed inside the collection box 805;

[0136] Multiple telescopic connecting rods 808 are rotatably installed inside each first threaded end 401. After the telescopic connecting rods 808 are connected, they rotate synchronously. The top telescopic connecting rod 808 is connected to the connecting shaft 803 and rotates synchronously. The bottom telescopic connecting rod 808 is connected to the drive blade 804 and rotates synchronously.

[0137] When the mixture flows through the interior of the connecting frame 304, it drives the turbine 8 to rotate. The turbine 8 drives the connecting shaft 803 to rotate, the connecting shaft 803 drives the telescopic connecting rod 808 to rotate, and the telescopic connecting rod 808 drives the drive blade 804 to rotate. When the drive blade 804 rotates, it drives the mixture to flow, so that the mixture flows along the space above the baffle 806, enters the interior of the collecting box 805 along the second connecting pipe 807, and then flows downward. Thus, after the mixture flows out spirally through the spiral channel 7, it enters the interior of the second connecting pipe 807 downward through the edge, forming a flow trajectory of the mixture to improve the fluidity of the mixture around the fruit and vegetable slices and improve the processing effect of the fruit and vegetable slices.

[0138] A method for processing fruit and vegetable crisps, the method comprising the following steps:

[0139] Step 1: Fruit and vegetable cleaning: Sort the fruits and vegetables, select the qualified ones and wash them to remove surface impurities;

[0140] Step 2, Fruit and vegetable blanching: Use hot water blanching or steam blanching to heat the fruits and vegetables to a specified temperature and maintain it for an appropriate time to destroy the enzyme activity in the fruits and vegetables;

[0141] Step 3, sealing the seepage: Immediately after blanching, transfer the fruits and vegetables to the fruit and vegetable crisping equipment. Add the pre-prepared mixture of starch and syrup to the equipment, seal and close the equipment, and pressurize the inside of the equipment through the pressure control component system. Keep the pressure within an effective range and maintain it for a certain period of time to allow the starch and syrup to penetrate into the fruits and vegetables under pressure.

[0142] Step 4, quick freezing of fruits and vegetables: After depressurization, remove the permeation-treated fruits and vegetables from the fruit and vegetable crisping equipment and transfer them to the quick-freezing equipment for quick freezing treatment.

[0143] As an optional embodiment, step three specifically includes:

[0144] The starch concentration is 35%, the syrup concentration is 30%, and the temperature of the mixture is controlled at 30°C by a temperature control component.

[0145] Example 1

[0155] The working principle of this invention is as follows: Fruit and vegetable slices are added to the inside of the sealed processing box 1, and then the sealed processing box 1 is sealed and closed. A mixture of starch and syrup is added to the inside of the sealed processing box 1 through the feed inlet 102. The pressure control component adjusts the pressure inside the sealed processing box 1 to a suitable level. At the same time, the liquid circulation component is activated to drive the mixture to flow, and the temperature control component adjusts the mixture to a suitable level. This allows the mixture to circulate at a specified temperature under the adjusted pressure environment. When the mixture flows through the fruit and vegetable slices, under the pressure environment, the starch and syrup fully penetrate into the fruit and vegetable slices, increasing the texture and flavor of the fruit and vegetable crisps and improving product quality.
