DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] See also Figure 1-Figure 9In an embodiment of the present invention, a mechanically supercharged oil heat exchange steam recondensation frying and drying device comprises a box body 1 and an oil drum 2 arranged in the box body 1, and a retaining ring 3 is arranged on the oil drum 2, and also comprises: a frying basket 5, which is movably arranged in the box body 1 and connected to a rotating drive mechanism and a lifting drive mechanism installed in the box body 1, the lifting drive mechanism can drive the frying basket 5 to move into the oil drum 2, and the rotating drive mechanism can drive the frying basket 5 to rotate in the oil drum 2; a reciprocating material shifting mechanism, wherein a plurality of groups are arranged in the frying basket 5, and when the rotating drive mechanism drives the frying basket 5 to rotate in the oil drum 2, the reciprocating material shifting mechanism is triggered, and can perform a shifting action on the material in the frying basket 5; a cover 12, which is movably arranged above the frying basket 5 and connected to two groups of timing trigger mechanisms arranged in the box body 1, and the timing trigger mechanism is triggered when the frying basket 5 passes through the retaining ring 3, and can prompt the cover 12 to move toward the frying basket 5 to close the top of the frying basket 5.

[0033] Among them, it is also necessary to add that the mechanical supercharged oil heat exchange steam recondensation frying and drying device also includes a liquid ring compressor 26 and an oil-water separator 27 arranged on the side of the box body 1, the liquid ring compressor 26 is connected with an air extraction pipe 28 and an oil extraction pipe 29, the air extraction pipe 28 and the oil extraction pipe 29 extend into the box body 1, a mixing delivery pipe 30 is connected between the liquid ring compressor 26 and the oil-water separator 27, and the oil-water separator 27 is also connected with an oil return pipe 31 extending into the box body 1; it should be pointed out that the liquid ring compressor 26 and the oil-water separator 27 are applications of the prior art, and the liquid ring compressor is a centrifugal compressor that uses liquid as a seal and coolant, which is widely used in chemical industry, pharmaceutical, food processing and other fields, and the working principle is based on an eccentrically configured impeller and a liquid (usually water or other liquid) injected into the cylinder. When the impeller rotates and reaches a certain speed, due to the action of centrifugal force, the liquid is thrown out and forms a liquid ring close to the inner wall of the cylinder. A periodically changing crescent-shaped space is formed between the impeller surface and the liquid ring, and this space is divided into several small chambers of different volumes by the blades. As the impeller rotates, the volume of these small chambers will expand and shrink periodically, thereby completing the intake, compression and exhaust processes; the oil-water separator 27 is a device for separating oil and water in sewage. Its main working principle is to use fluid mechanics theory and physical methods to collide and aggregate the oil droplets in the oily sewage through the kinetic energy of high-speed flow, thereby achieving the purpose of oil-water separation.

[0034] During operation, the liquid ring compressor 26 is used to reduce the pressure in the frying chamber and reduce nutritional loss. Water vapor and frying oil enter the liquid ring compressor 26 through the air extraction pipe 28 and the oil extraction pipe 29 respectively, and heat is exchanged and condensed in the liquid ring compressor 26 to form an oil-water mixture. The oil-water mixture enters the oil-water separator 27 through the mixing and conveying pipe 30. After separation treatment by the oil-water separator 27, the separated hot oil returns to the oil drum 2 through the oil return pipe 31 for recycling.

[0035] Specifically, during actual operation, the box door 101 on the box body 1 is opened, the material to be processed is placed in the frying basket 5, and then the box door 101 is closed. After the oil temperature reaches the required level, the lifting drive mechanism moves to drive the frying basket 5 and the cover 12 to move toward the oil drum 2. In addition, when the frying basket 5 passes through the enclosure ring 3 (that is, before the frying basket 5 enters the oil drum 2), the timing trigger mechanism moves to drive the cover 12 to move toward the frying basket 5, so that the cover 12 moves the frying basket 5. The port of the basket 5 is closed to prevent the material in the frying basket 5 from floating up and overflowing from the frying basket 5 after the frying basket 5 enters the oil drum 2, causing losses. During the frying process, the rotary drive mechanism works to drive the frying basket 5 to rotate in the oil drum 2, which is beneficial to the sufficient heat exchange between the material and the frying oil and the evaporation of water. At the same time, the reciprocating material-moving mechanism is triggered to continuously perform the moving action on the material in the frying basket 5, so that the looseness of the material in the frying basket 5 can be improved, the sufficient heat exchange between the material and the frying oil is further improved, and the effect of the drying process is improved.

[0036] After the drying process is completed, the material needs to be discharged. At this time, the lifting drive mechanism drives the frying basket 5 to move toward the outside of the oil cylinder 2. After the frying basket 5 moves into the enclosure ring 3, the rotating drive mechanism increases the rotation speed of the frying basket 5, and uses centrifugal force to deoil the material to reduce oil extraction loss. After the deoiling is completed, the frying basket 5 returns to its initial position, and the timing trigger mechanism drives the cover 12 to move away from the frying basket 5, releasing the closed state of the port of the frying basket 5, so as to facilitate the cooling and discharge of the material.

[0037] Please refer again Figure 6 , Figure 7 , Figure 8 as well as Fig. 9The reciprocating material-dispensing mechanism includes a cross bar 6 which is slidably mounted on the frying basket 5 and is arranged along the radial direction of the frying basket 5. Two vertical rods 8 are fixedly mounted on one end of the cross bar 6, and a roller 7 is mounted on the other end. The reciprocating material-dispensing mechanism also includes two sets of elastic support members mounted on the frying basket 5. The elastic support member includes a guide cylinder 9 which is fixed on the frying basket 5 and passes through the frying basket 5. A telescopic rod 10 which is slidably matched with the guide cylinder 9 is inserted into the inner side of the guide cylinder 9. One end of the telescopic rod 10 which is away from the guide cylinder 9 protrudes from the guide cylinder 9 and is fixed to the vertical rod 8. A columnar spring 11 is also arranged on the inner side of the guide cylinder 9. The two ends of the columnar spring 11 are respectively in contact with the inner end of the guide cylinder 9 and one end of the telescopic rod 10.

[0038] Specifically, a connecting plate is fixed at the bottom of the vertical pole 8, the cross bar 6 and the telescopic rod 10 are fixed on the connecting plate, the guide cylinder 9 and the telescopic rod 10 are parallel to the cross bar 6, and the length direction of the cross bar 6 and the telescopic rod 10 is perpendicular to the length direction of the vertical pole 8.

[0039] The cross bar 6 is arranged along the radial direction of the frying basket 5 and is slidably connected to the frying basket 5. One end of the cross bar 6 is located inside the frying basket 5, and the other end is located outside the frying basket 5. Two vertical rods 8 for scattering materials are fixedly provided on the end of the cross bar 6 located inside the frying basket 5, and a roller 7 is rotatably installed on the end located outside the frying basket 5.

[0040] A supporting seat 4 is fixedly mounted on the bottom wall of the oil cylinder 2, the supporting seat 4 is adapted to the frying basket 5, and a plurality of protrusions are equidistantly arranged on the outer wall of the supporting seat 4 along the circumference, and a first inclined surface 401 and a second inclined surface 402 cooperating with the roller 7 are respectively formed on both sides of the protrusions.

[0041] After the lifting drive mechanism drives the frying basket 5 to enter the oil cylinder 2, the supporting seat 4 supports the frying basket 5, and the roller 7 is located between two adjacent protrusions. Subsequently, when the rotating drive mechanism drives the frying basket 5 to rotate, the roller 7 makes a circular motion. When the roller 7 rolls along the first inclined surface 401, it will give way, that is, the roller 7 drives the cross bar 6 to slide toward the outside of the frying basket 5, and the vertical rod 8 moves away from the center of the frying basket 5 along the radial direction of the frying basket 5. Correspondingly, the telescopic rod 10 slides toward the inside of the guide cylinder 9. The cylindrical spring 11 is compressed, and after the roller 7 is separated from the first inclined surface 401, the cylindrical spring 11 will gradually reset, prompting the roller 7 to roll along the second inclined surface 402. During this process, the telescopic rod 10 gradually slides toward the outside of the guide cylinder 9, and the vertical rod 8 moves along the radial direction of the frying basket 5 close to the center of the frying basket 5, and this cycle is repeated. During the drying process of the material, multiple groups of the vertical rods 8 perform reciprocating gathering and expansion movements, which can effectively break up the material in the frying basket 5 and avoid uneven drying due to material agglomeration.

[0042] Please refer again Figure 4 The rotary drive mechanism includes a first drive motor 13 installed in the box body 1, a drive shaft 14 connected to the output end of the first drive motor 13, and a sleeve 15 slidably fitted with the drive shaft 14 through a transmission structure. One end of the sleeve 15 away from the first drive motor 13 is fixedly connected to the center of the bottom wall of the frying basket 5, the cover 12 is slidably arranged on the sleeve 15, and the sleeve 15 is also connected to the lifting drive mechanism.

[0043] In detail, the transmission structure includes two strip-shaped protrusions (not numbered in the figure) formed on the outer wall of the drive shaft 14 and two strip-shaped grooves provided on the inner wall of the sleeve 15. The strip-shaped grooves are adapted to the strip-shaped protrusions, and both are parallel to the central axis of the drive shaft 14.

[0044] The lifting drive mechanism includes an assembly plate 16 movably arranged in the box body 1, and the assembly plate 16 is rotatably connected to the sleeve 15. The two cannot move relative to each other in the axial direction. The timing trigger mechanism is arranged on the assembly plate 16, and the two ends of the assembly plate 16 are respectively connected to a group of threaded driving parts arranged in the box body 1.

[0045] Further, the threaded drive member includes a screw rod 24 rotatably installed in the box body 1 and a threaded sleeve 25 sleeved on the screw rod 24 and threadedly connected to the screw rod 24, the threaded sleeve 25 is fixed to the assembly plate 16, and a second drive motor 23 is also installed in the box body 1, one end of the screw rod 24 is connected to the output end of the second drive motor 23; it should be emphasized that the first drive motor 13 is a speed-regulating motor, and the second drive motor 23 is a servo motor; during operation, the second drive motor 23 drives the screw rod 24 to rotate forward or reverse, and the threaded sleeve 25 is threadedly matched with the screw rod 24 to drive the assembly plate 16 to rise or fall, and accordingly, the assembly plate 16 can drive the sleeve 15 to slide up or down on the drive shaft 14. During frying, the first drive motor 13 drives the drive shaft 14 to rotate, so that the drive shaft 14 can drive the sleeve 15 and the frying basket 5 to rotate through the strip-shaped protrusion and the strip-shaped groove. During the above process, the rotation speed of the first drive motor 13 is relatively low, so as to avoid the roller 7 and the supporting seat 4 from cooperating too quickly, resulting in the reciprocating frequency of the vertical rod 8 being too high, thereby causing the material in the frying basket 5 to be damaged by the vertical rod 8. After frying, when the frying basket 5 rises into the enclosure ring 3, the rotation speed of the first drive motor 13 increases, so as to utilize centrifugal force to de-oil the material. Therefore, in the specific implementation, the oil level in the oil drum 2 needs to be lower than the bottom end of the enclosure ring 3.

[0046] On the one hand, the rotary drive mechanism can facilitate the centrifugal de-oiling of the material when the frying basket 5 is in the enclosure circle 3. On the other hand, it can drive the frying basket 5 to rotate during the frying process, prompting the reciprocating material shifting mechanism to be triggered. The reciprocating material shifting mechanism performs a shifting action on the material to avoid uneven drying due to material agglomeration, thereby improving the effect of the frying and drying process.

[0047] Please refer again Figure 4 and Figure 5The assembly plate 16 is provided with a horizontal guide groove 1601 symmetrical along the center of the cover 12, and the timing trigger mechanism includes a slider 17 slidably engaged in the guide groove 1601 and a driven column 18 and a follower column 22 respectively fixed on both sides of the slider 17. A follower plate 21 is fixed on the cover 12, and a slide groove 2101 adapted to the follower column 22 is provided on the follower plate 21, and the slide groove 2101 is inclined outward from top to bottom, and the follower column 22 extends into the slide groove 2101 and is slidably connected to the follower plate 21. A limiting plate 20 is also fixed on the inner wall of the box body 1 through a connecting arm 19, and a guide groove adapted to the follower column 18 is provided on the limiting plate 20, and the follower column 18 passes through the guide groove and is slidably connected to the limiting plate 20, and the guide groove includes a connected inclined through groove 2001 and a vertical through groove 2002, and the inclined through grooves 2001 are close to each other from top to bottom.

[0048] When the frying basket 5 enters the oil cylinder 2, the driven column 18 first moves along the inclined through groove 2001 and then gives way, prompting the slider 17 to slide close to the sleeve 15 in the guide groove 1601. Correspondingly, the follower column 22 slides with the driven plate 21 through the slide groove 2101, prompting the cover 12 to slide close to the frying basket 5 on the sleeve 15. After the driven column 18 enters the vertical through groove 2002, the cover 12 completes the closure of the port of the frying basket 5. At this time, the frying basket 5 is located in the retaining ring 3. Subsequently, the cover 12 maintains the closed state of the port of the frying basket 5, and the frying basket 5 enters the oil cylinder 2.

[0049] As another embodiment of the present invention, a frying and drying method is also proposed, using the frying and drying device, comprising the following steps:

[0050] Step 1, placing the material to be processed in a frying basket 5;

[0051] Step 2: The lifting drive mechanism drives the frying basket 5 to move into the oil drum 2, and the timing trigger mechanism drives the cover 12 to close the top port of the frying basket 5;

[0052] Step 3: The rotary drive mechanism moves to drive the frying basket 5 to rotate in the oil drum 2, and the reciprocating material shifting mechanism is triggered to shift the materials in the frying basket 5;

[0053] Step 4: After frying, the lifting drive mechanism drives the frying basket 5 to move into the enclosure circle 3 to perform centrifugal de-oiling on the material;

[0054] Step 5: the frying basket 5 is reset, and the cover 12 releases the sealing state of the frying basket 5 .

[0055] As another embodiment of the present invention, application of the mechanically supercharged oil heat exchange steam recondensation frying and drying device in food material processing is also proposed.

[0056] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
