Description

Technical Field

[0001] The present invention relates to the technical field of food, and particularly relates to a high-nutrition cod puff chips deoiling and drying device and a drying method thereof. Background Art

[0002] Cod is a kind of fish with high protein and high nutritional value. Cod meat is often made into various nutritious foods. Cod chips are a kind of cod meat product. The sliced cod fish mince is fried and puffed by a frying and puffing device to form cod puff chips. After frying and puffing, the cod puff chips will contain a relatively high oil content, be relatively soft, and have poor crispness. At the same time, the excessive oil content affects the health of consumption. Therefore, a deoiling and drying device is needed to deoil and dry the fried and puffed cod puff chips. The cod puff chips are placed on the placement rack of the deoiling and drying device, and the oil liquid is separated from the cod puff chips by gravity and drops, and the blown cold air is used to make the oil contained in the cod puff chips separate from the cod puff chips faster, so that the obtained finished cod puff chips have less oil content and are more crispy and refreshing.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: when the existing deoiling and drying device deoils and dries the puffed cod puff chips, the cod puff chips need to be static, and the deoiling takes a long time. In order to accelerate the deoiling speed, relatively high-pressure cold air is often injected to improve the deoiling efficiency. At this time, it is easy to cause the static cod puff chips to move and collide with each other due to the blowing of the fast-flowing cold air. In the later stage of deoiling, the cod puff chips already have a certain degree of crispness. At this time, it is easy to cause the cod puff chips to collide with each other and break, and thus the integrity of the obtained finished product is poor. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-nutrition cod puff chips deoiling and drying device and a drying method thereof with high deoiling efficiency and high chip integrity in view of the defects and deficiencies of the prior art.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A high-nutrition cod puffed chip defatting and drying device, including a bracket, on which a drying cylinder is movably clamped.

A return spring is provided between the bottom surface of the centrifugal block and the inner wall of the pipe body. A elastic gasket made of silicone material is also provided on the upper surface of the disk body. The elastic gasket is provided with a perforation at the position of the oil discharge pipe.

[0006] Further improvement is: A power motor is provided on the bracket. A power gear is fixedly sleeved on the rotating shaft of the power motor. A driven gear is sleeved on the outer wall of one side of the drying cylinder. The power gear is meshed and connected with the driven gear.

[0007] Further improvement is: A second separation filter cylinder is also fixedly provided on the inner wall of the separation cylinder.

[0008] Further improvement is: A pulling convex block is provided at the end of the placement plate.

[0009] Further improvement is: A horn-shaped expansion pipe is provided on the top surface of the pipe body.

[0010] Further improvement is: An oil removal device is also slidably provided on the separation cylinder. The oil removal device includes a positive magnet slidably provided on the outer wall of the separation cylinder and a negative magnet slidably provided on the inner wall of the separation cylinder.

[0011] Further improvement is: A pull ring is provided on the positive magnet.

[0012] Further improvements are as follows: The positioning device includes a positioning piece disposed at the bottom of the placing plate and attached to the inner wall of the separation cylinder on one side, and a sliding groove integrally formed on the side of the positioning piece close to the separation cylinder. A fixing block with a hemispherical end is slidably disposed in the sliding groove. An external pushing spring is provided between the end of the fixing block and the inner wall of the sliding groove. The positioning device further includes a fixing groove integrally formed on the inner wall of the separation cylinder and capable of cooperating with the fixing block.

[0013] To achieve the above object, the present invention can also adopt the following technical solutions: A drying method for high-nutrition cod puffed chips, which applies a deoiling and drying device for high-nutrition cod puffed chips, includes the following steps:

[0014] Step 1: Remove the air flow pipe of a deoiling and drying device for high-nutrition cod puffed chips, and take out the placing plate, and perform high-temperature disinfection on the placing plate and the separation plate.

[0015] Step 2: Place the puffed cod chips into the separation plate on the placing plate of a deoiling and drying device for high-nutrition cod puffed chips, and put the placing plate with the cod chips into the separation cylinder, and position and fix the placing plate through the positioning device.

[0016] Step 3: Install the air flow pipe at the end of the input cylinder and connect it to the air flow pump, so that the air flow can enter the separation cylinder from the input cylinder through the air flow pipe.

[0017] Step 4: Rotate the drying cylinder at a high speed, and quickly separate the oil on the cod chips through the centrifugal force of rotation, and cooperate with the air flow input by the air flow pipe to dry and crispify the cod chips.

[0018] Step 5: Stop rotating the drying cylinder, make the angle of the stopped drying cylinder the same as that before starting, remove the air flow pipe and take out the placing plate to obtain the finished cod chips.

[0019] After adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0020] The present invention places the fried puffed cod chips on the placing plate. After placing, by rotating the drying cylinder at a high speed to generate centrifugal force, the oil on the cod crispy skin is separated through the centrifugal force, greatly improving the separation speed of the oil on the cod chips, and cooperating with the air flow pumped in by the air flow pipe to make the cod chips quickly crispify, with high deoiling efficiency.

[0021] The present invention separates the oil on the cod chips through the centrifugal force generated by the high-speed rotating drying cylinder, and the cod chips are placed on the separation plate in batches. Then, when rotating at a high speed, a larger air flow can be pumped in through the air flow pipe to greatly improve the deoiling speed, and the cod chips are protected by the separation plate, thereby avoiding the phenomenon that the cod chips are blown by the air flow and accumulate together and are crushed by mutual extrusion, making the integrity of the finished product higher.

[0022] In the process of centrifugally separating grease in the present invention, after the centrifugal rotation ends, the oil liquid cleaning device can be quickly pulled at the same time, and after the machine stops, the oil liquid in the inner cavity of the separation cylinder can be quickly cleaned through the oil liquid cleaning device, avoiding the oil liquid from dripping back onto the cod chips again, with good oil removal effect and higher degree of crispness of the cod chips.

[0031] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0032] Refer to Figures 1-7As shown in the figure, the technical solution adopted in this specific embodiment is as follows: A high-nutrition cod puffed chip deoiling and drying device, including a bracket 1, on which a drying cylinder 2 is movably clamped. The drying cylinder 2 includes an input cylinder 22 and an output cylinder 23. A separation cylinder 21 is provided between the input cylinder 22 and the output cylinder 23. A screen-like placement plate 24 is detachably provided in the separation cylinder 21. A positioning device 25 is provided between the bottom of the placement plate 24 and the inner wall of the drying cylinder 2. The positioning device 25 includes a positioning piece 251 provided at the bottom of the placement plate 24 and fitting against the inner wall of the separation cylinder 21 on one side, and a sliding groove 253 integrally formed on the side of the positioning piece 251 close to the separation cylinder 21. A fixing block 255 with a hemispherical end is slidably arranged in the sliding groove 253. An external pushing spring 254 is provided between the end of the fixing block 255 and the inner wall of the sliding groove 253. The positioning device 25 further includes a fixing groove 252 integrally formed on the inner wall of the separation cylinder 21 that can cooperate with the fixing block 255. The upper surface of the placement plate 24 is provided with a number of separation disks 29. The separation disk 29 includes a disk body 31 provided on the upper surface of the placement plate 24 and a side bar 33 provided at the edge of the disk body 31. A number of air holes 34 are provided on the side bar 33. A number of oil discharge pipes 32 penetrate through the disk body 31. The oil discharge pipe 32 includes a pipe body 321 penetrating through the disk body 31 and a flow dividing plate 323 provided in the pipe body 321. A diversion block 328 with a hemispherical cross-section is provided at the top of the flow dividing plate 323. A contraction block 324 is provided between the inner wall of the pipe body 321 and the side wall of the flow dividing plate 323. A bullet-shaped centrifugal block 325 is slidably and fittingly arranged in the inner cavity of the contraction block 324. A return spring 327 is provided between the bottom surface of the centrifugal block 325 and the inner wall of the pipe body 321. A elastic gasket 36 made of silica gel is further provided on the upper surface of the disk body 31. The elastic gasket 36 is provided with a perforation at the position of the oil discharge pipe 32. The end of the input cylinder 22 is detachably connected with an air flow pipe 5. The cod chips are placed on the separation disks 29 of the placement plate 24 for separation. At the same time, air flow is introduced through the air flow pipe 5. Subsequently, the separation cylinder 21 rotates at a high speed, and the oil on the cod chips is separated by centrifugal force. When in use, the air flow pipe 5 connected to the input cylinder 22 of the drying cylinder 2 is removed. Then, the placement plate 24 contained in the separation cylinder 21 is pulled upward forcefully, so that the fixing block 255 of the positioning device is disengaged from the fixing groove 252. At this time, the placement plate 24 can be taken out, and the puffed cod chips are placed on the separation disks 29 on the placement plate 24, so that the disk body 31 of the separation disk 29 supports the cod chips, and the movement of the cod chips is restricted by the side bar 33. Then, the placement plate 24 is put into the separation cylinder 21, and the positioning piece 251 of the positioning device 25 is fitted against the inner wall of the separation cylinder 21 and pressed downward, so that the fixing block 255 is pressed into the sliding groove 253 and the external pushing spring 254 is compressed to generate elastic force. When the fixing block 255 is moved to the position of the fixing groove 252, the fixing block 255 can be ejected by the external pushing spring 254.Insert the fixed block 255 into the fixed slot 252. At this time, the longitudinal positioning of the placement plate 24 can be carried out, and the transverse positioning is carried out in cooperation with the two positioning pieces 251. Then, connect the air flow pipe 5 to the input cylinder 22 and pump air into it. At the same time, rotate the drying cylinder 2 at a high speed. At this time, the separation cylinder 21 of the drying cylinder 2 rotates at a high speed, which can drive the placement plate 24 and the separation disc 29 and the cod crispy slices on it to rotate at a high speed. The centrifugal force generated is applied to the cod crispy slices, so as to separate the grease on the cod crispy skin through the centrifugal force. The elastic gasket 36 on the separation disc 29 absorbs the pressing force brought by the centrifugal force to the cod crispy slices. At the same time, the side rail 33 is used to limit the displacement of the cod crispy slices. At the same time, the air holes 34 provided on the side rail 33 enable the air pumped by the air flow pipe 5 to pass through the air holes 34 and blow on the cod crispy slices, blowing away the evaporated and rising grease. After the oil liquid is separated from the cod crispy slices, it will be pressed on the disc body 31 by the centrifugal force, so that the oil liquid enters the drain pipe 32 and flows along the pipe body 321 of the drain pipe 32 and is shunted by the shunt plate 323. At the same time, the centrifugal force is applied to the centrifugal block 325 to make it move downward and squeeze the return spring 327. At the same time, a gap is generated between the two sides of the centrifugal block 325 and the shrinkage block 324. At this time, the oil liquid can be discharged outward through the gap under the action of the centrifugal force. When the rotation stops, the centrifugal force disappears. At this time, the return spring 327 can push the centrifugal block 325 upward to re-close the pipe body 321, preventing the oil liquid from flowing back and maintaining the dryness and crispness of the deoiled cod crispy slices. At this time, the separation speed of the grease on the cod crispy slices can be greatly improved, and the air flow pumped by the air flow pipe 5 is used to make the cod crispy slices crispy at a high speed, and the deoiling efficiency is high;

[0033] A power motor 3 is provided on the bracket 1. A power gear 4 is fixedly sleeved on the rotating shaft of the power motor 3. A driven gear 6 is sleeved on the outer wall of one side of the drying cylinder 2. The power gear 4 is meshed and connected with the driven gear 6, which is beneficial to output power through the power motor 3 and cooperate with the driven gear 6 and the power gear 4 to make the drying cylinder 2 rotate automatically at a high speed, further improving the automation and deoiling efficiency;

[0034] A second separation filter cylinder 27 is also fixedly provided on the inner wall of the separation cylinder 21, which is beneficial to collect the accidentally dropped cod crispy slices and prevent them from directly falling on the inner wall of the separation cylinder 21 and re-absorbing oil;

[0035] A pulling convex block 28 is provided at the end of the placement plate 24, which is beneficial to better lift the placement plate 24 through the pulling convex block 28;

[0036] A horn-shaped expansion pipe 322 is provided on the top surface of the pipe body 321, which is beneficial to expand the oil collection range of the pipe body 321;

[0037] A fluid removal device 26 is also slidably provided on the separation cylinder 21. The fluid removal device 26 includes a positive magnet 261 slidably disposed on the outer wall of the separation cylinder 21 and a negative magnet 262 slidably disposed on the inner wall of the separation cylinder 21. A triangular scraping ring 263 is provided on the side wall of the negative magnet 262. When the rotation for oil removal ends, quickly pull the positive magnet 261, so that the positive magnet 261 drives the negative magnet 262 to move through magnetic force and drives the scraping ring 263 to move, thereby scraping the oil fluid on the inner wall of the separation cylinder 21 to one side, preventing the oil fluid from dripping onto the cod crispy chips again from a high place after stopping the rotation, with good oil removal effect and higher crispness degree of the cod crispy chips;

[0038] A pull ring 264 is provided on the positive magnet 261, which is beneficial to making the pulling of the positive magnet 261 more labor-saving and convenient.

[0039] The present invention also provides a drying method for high-nutrition cod puffed crispy chips, which applies a high-nutrition cod puffed crispy chip oil removal and drying device, and includes the following steps:

[0040] Step 1: Remove the air flow pipe 5 of a high-nutrition cod puffed crispy chip oil removal and drying device, and take out the placement plate 24, and perform high-temperature disinfection on the placement plate 24 and the separation disk 29;

[0041] Step 2: Put the puffed cod crispy chips into the separation disk 29 on the placement plate 24 of a high-nutrition cod puffed crispy chip oil removal and drying device, and put the placement plate 24 with the cod crispy chips into the separation cylinder 21, and position and fix the placement plate 24 through the positioning device 25;

[0042] Step 3: Install the air flow pipe 5 at the end of the input cylinder 22 and connect it to an air flow pump, so that the air flow can enter the separation cylinder 21 from the input cylinder 22 through the air flow pipe 5;

[0043] Step 4: Rotate the drying cylinder 2 at a high speed, and quickly separate the oil on the cod crispy chips through the rotational centrifugal force, and cooperate with the air flow input by the air flow pipe 5 to dry and crispify the cod crispy chips;

[0044] Step 5: Stop rotating the drying cylinder 2, so that the stopped drying cylinder 2 has the same angle as before starting, remove the air flow pipe 5 and take out the placement plate 24 to obtain the finished cod crispy chips.

[0045] Working principle of the present invention: When the present invention is in use, the air flow pipe 5 connected to the input cylinder 22 of the drying cylinder 2 is removed. Then, the placement plate 24 contained in the separation cylinder 21 is pulled upward forcefully, so that the fixing block 255 of the positioning device is disengaged from the fixing groove 252. At this time, the placement plate 24 can be taken out, and the puffed cod chips are placed on the separation plate 29 on the placement plate 24, so that the plate body 31 of the separation plate 29 supports the cod chips, and the side bars 33 are used to limit the movement of the cod chips. Then, the placement plate 24 is placed into the separation cylinder 21, and the positioning piece 251 of the positioning device 25 is attached to the inner wall of the separation cylinder 21 and pressed downward, so that the fixing block 255 is pressed into the sliding groove 253 and presses the outer pushing spring 254 to generate elastic force. When the fixing block 255 is moved to the position of the fixing groove 252, the fixing block 255 can be ejected by the outer pushing spring 254 and inserted into the fixing groove 252. At this time, the placement plate 24 can be longitudinally positioned, and the two positioning pieces 251 are used for transverse positioning. Then, the air flow pipe 5 is connected to the input cylinder 22, and air is pumped in. At the same time, the drying cylinder 2 is rotated at a high speed. At this time, the separation cylinder 21 of the drying cylinder 2 rotates at a high speed, so that the separation cylinder 21 drives the placement plate 24, the separation plate 29 thereon and the cod chips to rotate at a high speed. The centrifugal force generated is applied to the cod chips, so as to separate the oil on the cod crispy skin through the centrifugal force. The elastic gasket 36 on the separation plate 29 absorbs the pressing force brought by the centrifugal force to the cod chips. At the same time, the side bars 33 are used to limit the displacement of the cod chips. At the same time, the air holes 34 provided on the side bars 33 enable the air pumped by the air flow pipe 5 to pass through the air holes 34 and blow on the cod chips, blowing away the evaporated and rising oil. After the oil is separated from the cod chips, it will be pressed on the plate body 31 by the centrifugal force, so that the oil enters the drain pipe 32 and flows along the pipe body 321 of the drain pipe 32 and is shunted by the shunt plate 323. At the same time, the centrifugal force is applied to the centrifugal block 325 to make it move downward and press the return spring 327. At the same time, a gap is generated between the two sides of the centrifugal block 325 and the shrinkage block 324. At this time, the oil can be discharged outward through the gap under the action of the centrifugal force. When the rotation stops, the centrifugal force disappears. At this time, the return spring 327 pushes the centrifugal block 325 upward to re-close the pipe body 321, preventing the oil from flowing back and maintaining the dryness and crispness of the defatted cod chips. At this time, the separation speed of the oil on the cod chips can be greatly improved, and the air flow pumped by the air flow pipe 5 is used to make the cod chips crispy at a high speed, with high defatting efficiency.
