Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, specifically to a phased array precision controlled ultrasonic fryer and method. Background Technology

[0002] Ultrasonic frying technology has been widely used in the food processing field because it can improve the oil convection efficiency and reduce the oil absorption rate of food through the ultrasonic cavitation effect. However, existing similar equipment still has obvious technical defects, which are illustrated below: 1. Utility model application No. 202022195164.8 discloses an ultrasonic fryer, including a housing. An ultrasonic groove and an ultrasonic transducer are provided at the bottom of the housing. The ultrasonic groove and the ultrasonic transducer are connected. A heater and a heating tube are provided above the ultrasonic groove inside the housing. The heater and the heating tube are connected. A partition is provided between the ultrasonic groove and the heating tube. An oil tank for holding oil is provided above the heating tube inside the housing. A wire basket for holding food is provided in the oil tank. The utility model also includes a control panel on the housing for controlling the ultrasonic fryer. The ultrasonic waves and ultrasonic transducers in this utility model can save the frying time of food and make the fried food taste good and not greasy.

[0003] However, this utility model also has the following drawbacks: (1) It only uses a single food basket for simple filtration, and the residue can easily penetrate the filter plate and be deposited at the bottom of the oil storage tank. In addition, the number of ultrasonic transducers is small and the distribution is fixed, and the ultrasonic field strength is uneven, which cannot meet the frying requirements of different materials.

[0004] (2) Foods with high density usually need to be stirred. If they cannot be stirred effectively, they are prone to uneven heating due to food accumulation, which can cause some food to be overcooked on the outside and undercooked on the inside. This new type of food does not provide a reliable stirring device.

[0005] 2. Utility model application No. 202421527858.9 discloses an ultrasonic fryer, comprising: a housing, an ultrasonic groove inside the housing, an oil pot inside the ultrasonic groove, and a hollow plate fixedly installed on the top of the housing; by activating an electric push rod to retract, a linked L-shaped plate slides and moves downward inside the hollow plate, causing a flipping plate on the sliding plate to extend into the oil pot; by activating a motor, the motor drives a disc to rotate, causing the sliding plate to rotate on the disc and slide on a grooved plate, causing the grooved plate to rotate on the L-shaped plate, thereby flipping the fried food. Simultaneously, by rotating the sliding plate on the disc and sliding it on the grooved plate, the position of the flipping plate on the fried food can be changed, making the fried food heated more evenly, thus achieving the purpose of automatic flipping of the fried food, effectively avoiding the harm caused by splashing high-temperature oil droplets, and reducing safety hazards.

[0006] However, this utility model also has the following drawbacks: (1) The stirring method involves the constant contact of the fried food with a turning plate outside the oil pot, which promotes the continuous movement of the fried food. Due to the lack of intelligence of the mechanical equipment, it is not possible to effectively control the force and angle of stirring the fried food like a human. This can easily cause the fried food to break and crumble, resulting in food waste and oil pollution, and affecting the appearance of the final fried food.

[0007] (2) Its ultrasonic system is still in a fixed working mode and cannot adjust the ultrasonic field according to real-time working conditions (such as material distribution and temperature changes), resulting in local overheating and scorching of the material or incomplete cooking inside.

[0008] Furthermore, existing ultrasonic transducers are mostly concentrated in a single location, resulting in incomplete ultrasonic field coverage and poor field adjustment flexibility. This makes it difficult to achieve precise frying control for materials of different shapes and distributions, thus limiting the stability of frying quality. Therefore, there is an urgent need to design an ultrasonic fryer with precise ultrasonic field control capabilities, efficient residue handling functions, and the ability to control food displacement to achieve a stirring effect without damaging the food, thereby overcoming the shortcomings of existing technologies. Summary of the Invention

A sealing ring is provided on the inner edge of the outer surface of the rectangular frame, and multiple threaded holes are provided on the outer edge of the outer surface of the rectangular frame. The back plate of the drawer-type slag collection plate has connection holes corresponding to the threaded holes. The drawer-type slag collection plate is detachably and sealed to the oil storage tank by fixing bolts that pass through the connection holes and are screwed to the threaded holes. The bottom of the drawer-type slag collection plate has several first filter holes. A door is provided on the side wall of the machine body opposite to the drawer-type slag collection plate. The bottom of the oil storage tank is an inclined surface, and an oil drain pipe is connected to one end of the bottom of the oil storage tank. A valve is provided on the oil drain pipe.

[0015] Preferably, the box-type filter plate includes a square filter plate body and a surrounding plate located at the top of the filter plate body and forming a cubic structure. Both the surrounding plate and the filter plate body are provided with a plurality of second filter holes. The diameter of the second filter holes is larger than that of the first filter holes. A plurality of spherical protrusions are also evenly distributed between the second filter holes on the filter plate body. The four corners of the bottom end of the filter plate body are respectively provided with support rods along the vertical direction.

[0016] Preferably, the food distribution control component includes four rectangularly arranged lifting components.

One end of the movable seat slides against the inner wall of the oil storage tank. The lower surface of the stepped structure has a groove structure. The lower ends of four support rods are inserted into the corresponding groove structures and slide against the bottom of the groove structure through stainless steel balls.

[0017] Preferably, the heating component is a first heating tube or several second heating tubes coiled on the inner surface of the outer wall of the oil storage tank.

[0019] A method for using a phased array precision controlled ultrasonic fryer includes a food distribution control method and a phased array frying method.

[0020] Preferably, the food distribution control method includes a vertical lifting mode, a repeated tilting mode, and a sequential tilting mode; The vertical lifting mode is as follows: the intelligent controller synchronously controls the operation of four drive motors, and controls the lifting of the box filter plate by forward and reverse rotation, so that the food raw materials located in the box filter plate are at different oil depths or are removed from the oil surface; The repeated tilting mode is as follows: Based on the distribution of food ingredients fed back by the thermal imaging camera, the intelligent controller controls the two drive motors on the side away from the side with more food ingredients to move one end of the box filter plate downward, and the food on the side with more food ingredients slides to the opposite side, promoting food dispersion. By controlling the box filter plate to repeatedly tilt left and right, or repeatedly tilt forward and backward, or by combining left and right tilting with forward and backward tilting, the food ingredients are promoted to be evenly distributed inside the box filter plate. When the image information fed back by the thermal imaging camera reaches the preset standard of the intelligent controller, the intelligent controller uses four drive motors to keep the box filter plate in a horizontal position. The sequential tilting mode is as follows: the intelligent controller first controls one corner of the box filter plate to move downward by a set distance according to the preset intelligent algorithm, and then moves the adjacent corner downward at the same time as the corner moves upward. During this process, except for the corner that moves downward, the other corners all cooperate to keep each stainless steel ball in contact with the bottom of the corresponding groove structure, thereby forming the action of the box filter plate tilting in the direction of each corner in sequence, so as to make the food raw materials in the box filter plate evenly stirred.

[0021] Preferably, the phased array frying method includes the following steps: Step 1: Open the top cover and add a measured amount of cooking oil to the oil storage tank; close the top cover and start the heating component; use the first temperature sensor to determine whether the cooking oil has been heated to the required temperature. Once the required temperature is reached, control the moving seat to rise and fall, and measure the oil temperature at different depths. When the temperature measured by the second temperature sensor is consistent with the temperature measured by the first temperature sensor, it means that the temperature of the cooking oil has been accurately controlled. Step 2: Open the top cover and put the food ingredients to be fried into the oil storage tank; close the top cover and start the repeated tilting mode to make the food ingredients evenly distributed on the box filter plate. Step 3: Start the ultrasonic transducer. Based on the temperature information of the food surface collected by the thermal imaging camera, the intelligent controller controls the corresponding ultrasonic transducer to work through the phased array control module to promote even heating of the food surface. Step 4: After the set interval, pause the ultrasonic transducer and start the sequential tilting mode to ensure that the food ingredients are evenly stirred; then, start the ultrasonic transducer again and repeat the operation; during the above process, the intelligent controller dynamically regulates the oil temperature through the heating component based on the preset threshold of oil temperature. Step 5: Based on the preset time and the food surface temperature information monitored by the thermal imaging camera, the intelligent controller determines that the food is fried and turns off the power of the fryer; Step 6: The operator opens the top cover, uses tools to remove the entire box-type filter plate from the oil storage tank, removes the fried food, and pours out the larger food residues filtered by the box-type filter plate; then, opens the drain pipe to drain the oil and the small residues remaining in the oil storage tank. Step 7: The operator opens the door, takes out the drawer-type slag collection plate, and pours out the smaller residues on the drawer-type slag collection plate; Step 8: After cleaning the oil storage tank, box-type filter plate, and drawer-type slag collection plate, install them separately, close the door and top cover, and prepare for the next use.

[0022] The present invention provides a phased array precision field-controlled ultrasonic fryer and method, which has the following beneficial effects: The present invention achieves the technical effect of efficient residue cleaning, dynamic adaptation of ultrasonic field, and uniform heating of oil by integrating dual-stage residue treatment, phased array ultrasonic field control, controllable uniform heating, and automatic food position adjustment.

[0028] In this embodiment, to facilitate the movement and leveling of the fryer, casters with brakes and four adjustable height support feet 17 can be installed at the bottom of the machine body; the dual-stage residue treatment component is used to filter residues of different sizes to avoid contaminating the cooking oil; the food distribution control component is used to automatically and evenly distribute food ingredients without manual intervention, and to provide uniform stirring when food density is high and prone to sedimentation, avoiding poor food processing due to food accumulation; the phased array ultrasonic component can precisely control the local field strength according to temperature distribution and material state to avoid problems such as burnt exterior and burnt interior and local scorching, further ensuring the frying effect; the material monitoring component 20 is used to monitor the distribution state and heating temperature of food ingredients and provide real-time feedback to the intelligent controller; the intelligent controller is responsible for the automatic operation of the entire fryer.

[0029] Example 2: like Figure 1-3 As shown, the phased array ultrasonic component includes several ultrasonic transducers 7 and an ultrasonic generator. The intelligent controller includes a phased array control module 14. The oil storage tank 3 has a cubic structure. Multiple ultrasonic transducers 7 are arranged in an array on the outer surface of each side wall and the outer surface of the lower end of the cubic structure.

The transducer layout is optimized as follows: 20 transducers are distributed in a rectangular array at the bottom of the oil storage tank (adjacent spacing 5cm), and 15 transducers are distributed in a rectangular array on each of the four sides (adjacent spacing 4cm). The side transducers cooperate with the bottom transducers to ensure that the ultrasonic field covers the entire oil storage tank without dead angles. The transducer vibration end is rigidly connected to the oil storage tank wall to ensure efficient transmission of ultrasonic energy.

Both the surrounding plate 401 and the filter plate body 402 are provided with a plurality of second filter holes 404. The diameter of the second filter holes 404 is larger than that of the first filter holes. A plurality of spherical protrusions 405 are also evenly distributed between the second filter holes 404 on the filter plate body 402. The four corners of the bottom end of the filter plate body 402 are respectively provided with support rods 403 along the vertical direction. The bottom end of the support rods 403 is provided with ball seats 4032. Stainless steel balls 4031 are slidably connected in the ball seats 4032.

[0035] This embodiment provides the basic structure of a two-stage residue treatment component.

[0036] Example 6: like Figure 4-7As shown, the food distribution control component includes four rectangularly arranged lifting components. Each lifting component includes a vertically arranged lead screw 307. The two ends of the lead screw 307 are respectively rotatably connected to mounting plates 302 / 305.

[0039] like Figure 5 As shown, the side wall of the movable seat 304 is provided with a second temperature sensor 306 and a wiring conduit 303 extending vertically upward. The second temperature sensor 306 is connected to the intelligent controller via a wire passing through the wiring conduit 303.

[0040] Example 8: Based on the above embodiments, this embodiment discloses a method for using a phased array precision controlled ultrasonic fryer, such as... Figure 1-8 As shown, this includes methods for regulating food distribution and phased array frying methods.

[0041] The food distribution control method includes vertical lifting mode, repeated tilting mode, and sequential tilting mode. The vertical lifting mode is as follows: the intelligent controller synchronously controls the operation of four drive motors, and controls the box filter plate 4 to lift and lower through forward and reverse rotation, so that the food raw materials located in the box filter plate 4 are at different oil depths or above the oil surface; as needed, the food raw materials are placed in hot oil at a certain depth for frying. After frying, the fried food can be lifted above the surface of the cooking oil, and after the oil on the surface of the fried food is drained, the top cover can be opened and the fried food can be taken out.

[0042] The repeated tilting mode is as follows: Based on the distribution of food ingredients fed back by the thermal imaging camera, the intelligent controller controls the two drive motors on the side away from the side with more food ingredients to move one end of the box filter plate 4 downward. The food on the side with more food ingredients slides to the opposite side due to its own gravity. During the sliding process, the food is dispersed. By controlling the box filter plate 4 to repeatedly tilt left and right, or repeatedly tilt forward and backward, or by combining left and right tilting with forward and backward tilting, the food ingredients are evenly distributed inside the box filter plate 4. When the image information fed back by the thermal imaging camera or the ultrasonic ranging sensor reaches the preset standard of the intelligent controller, the intelligent controller uses four drive motors to keep the box filter plate in a horizontal position. The sequential tilting mode is as follows: the intelligent controller first controls one corner of the box filter plate 4 to move downward by a set distance according to the preset intelligent algorithm, and then moves the adjacent corner downward at the same time as the corner moves upward. During this process, except for the corner that moves downward, the other corners all cooperate to keep each stainless steel ball in contact with the bottom of the corresponding groove structure, thereby forming the action of the box filter plate tilting in the direction of each corner in sequence, so that the food raw materials in the box filter plate 4 are evenly stirred.

[0043] like Figure 1-8 As shown, the phased array frying method includes the following steps: Step 1: Open the top cover and add a measured amount of cooking oil into the oil storage tank 3; close the top cover and start the heating component; use the first temperature sensor to determine whether the cooking oil has been heated to the required temperature. Once the required temperature is reached, control the moving seat to lift and lower, and measure the oil temperature at different depths. When the temperature measured by the second temperature sensor is consistent with the temperature measured by the first temperature sensor, it means that the temperature of the cooking oil has been accurately controlled. Step 2: Open the top cover and put the food ingredients to be fried into the oil storage tank 3; close the top cover 1 and start the repeated tilting mode to make the food ingredients evenly distributed on the box filter plate 4. Step 3: Start the ultrasonic transducer 7. Based on the temperature information of the food raw material surface collected by the thermal imaging camera, the intelligent controller controls the corresponding ultrasonic transducer to work through the phased array control module to promote the even heating of the food surface. Step 4: After the set interval, pause the ultrasonic transducer 7 and start the sequential tilting mode to ensure that the food ingredients are evenly stirred; then, start the ultrasonic transducer 7 again and repeat this operation to avoid the food piling up and causing a decrease in frying quality; during the above process, the intelligent controller dynamically controls the oil temperature through the heating components according to the preset threshold of oil temperature. Step 5: Based on the preset time and the food surface temperature information monitored by the thermal imaging camera, the intelligent controller determines that the food is fried and turns off the power of the fryer; Step 6: The operator opens the top cover, uses tools to remove the entire box-type filter plate from the oil storage tank, takes out the fried food, and pours out the larger food residues filtered out; then, opens the drain pipe to drain the oil and the small residues remaining in the oil storage tank. Step 7: The operator opens the door, takes out the drawer-type slag collection plate, and pours out the smaller residues on the drawer-type slag collection plate; Step 8: After cleaning the oil storage tank, box-type filter plate, and drawer-type slag collection plate, install them separately, close the door and top cover, and prepare for the next use.

10. The method of using a phased array precision controlled ultrasonic fryer as described in claim 9, characterized in that, This includes methods for regulating food distribution and phased array frying methods; The food distribution control methods include vertical lifting mode, repeated tilting mode, and sequential tilting mode; The vertical lifting mode is as follows: the intelligent controller synchronously controls the operation of four drive motors, and controls the lifting of the box filter plate by forward and reverse rotation, so that the food raw materials located in the box filter plate are at different oil depths or are removed from the oil surface; The repeated tilting mode is as follows: Based on the distribution of food ingredients fed back by the thermal imaging camera, the intelligent controller controls the two drive motors on the side away from the side with more food ingredients to move one end of the box filter plate downward, and the food on the side with more food ingredients slides to the opposite side, promoting food dispersion. By controlling the box filter plate to repeatedly tilt left and right, or repeatedly tilt forward and backward, or by combining left and right tilting with forward and backward tilting, the food ingredients are promoted to be evenly distributed inside the box filter plate. When the image information fed back by the thermal imaging camera reaches the preset standard of the intelligent controller, the intelligent controller uses four drive motors to keep the box filter plate in a horizontal position. The sequential tilting mode is as follows: the intelligent controller first controls one corner of the box filter plate to move downward by a set distance according to the preset intelligent algorithm, and then moves the adjacent corner downward at the same time as the corner moves upward. During this process, except for the corner that moves downward, the other corners all cooperate to keep each stainless steel ball in contact with the bottom of the corresponding groove structure, thereby forming the box filter plate to tilt in the direction of each corner in sequence, so that the food raw materials in the box filter plate are evenly stirred. The phased array frying method includes the following steps: Step 1: Open the top cover and add a measured amount of cooking oil to the oil storage tank; close the top cover and start the heating component; use the first temperature sensor to determine whether the cooking oil has been heated to the required temperature. Once the required temperature is reached, control the moving seat to rise and fall, and measure the oil temperature at different depths. When the temperature measured by the second temperature sensor is consistent with the temperature measured by the first temperature sensor, it means that the temperature of the cooking oil has been accurately controlled. Step 2: Open the top cover and put the food ingredients to be fried into the oil storage tank; Close the top cover and start the repeated tilting mode to distribute the food ingredients evenly on the box-type filter plate; Step 3: Start the ultrasonic transducer. Based on the temperature information of the food surface collected by the thermal imaging camera, the intelligent controller controls the corresponding ultrasonic transducer to work through the phased array control module to promote even heating of the food surface. Step 4: After the set interval, pause the ultrasonic transducer and start the sequential tilting mode to ensure that the food ingredients are evenly stirred; then, start the ultrasonic transducer again and repeat the operation; during the above process, the intelligent controller dynamically regulates the oil temperature through the heating component based on the preset threshold of oil temperature. Step 5: Based on the preset time and the food surface temperature information monitored by the thermal imaging camera, the intelligent controller determines that the food is fried and turns off the power of the fryer; Step 6: The operator opens the top cover, uses tools to remove the entire box-type filter plate from the oil storage tank, removes the fried food, and pours out the larger food residues filtered by the box-type filter plate; then, opens the drain pipe to drain the oil and the small residues remaining in the oil storage tank. Step 7: The operator opens the door, takes out the drawer-type slag collection plate, and pours out the smaller residues on the drawer-type slag collection plate; Step 8: After cleaning the oil storage tank, box-type filter plate, and drawer-type slag collection plate, install them separately, close the door and top cover, and prepare for the next use.
