Description

Technical Field

[0001] The invention relates to the technical field of food, and in particular to a high-nutrition cod puffed crisp chip 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 flakes are a kind of cod meat product. The cod fish paste cut into slices is fried and puffed by frying and puffing equipment to form cod flakes. After frying and puffing, the cod flakes will contain higher oil content, be softer and less crispy. At the same time, too high oil content affects the health of consumption, and then it is necessary to use deoiling and drying equipment to deoil and dry the fried and puffed cod flakes. The cod flakes are placed on the placement rack of the deoiling and drying equipment, and the oil is separated from the cod flakes by gravity and falls. The cold air blown in is used to separate the oil contained in the cod flakes from the cod flakes faster, so that the obtained cod flakes have less oil content and are more crispy and refreshing.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: the existing de-oiling and drying equipment needs to leave the puffed cod crisps to stand when de-oiling and drying, and de-oiling takes a long time. In order to speed up the de-oiling speed, relatively high-pressure cold air is often injected to improve the de-oiling efficiency. At this time, it is easy to cause the stationary cod crisps to be blown by the fast-flowing cold air and move and collide with each other. The cod crisps in the later stage of de-oiling have a certain degree of crispness. At this time, it is easy to cause the cod crisps to collide with each other and break, and the obtained finished product has poor integrity. Summary of the invention

[0012] A further improvement is that a pull ring is provided on the positive magnet.

[0013] Further improvement is: the positioning device includes a positioning piece arranged at the bottom of the placing plate and with one side in contact with the inner wall of the separation cylinder, and a sliding groove integrally formed on the side of the positioning piece close to the separation cylinder, a fixed block with a hemispherical end slidingly arranged in the sliding groove, an outward push spring is provided between the end of the fixed block and the inner wall of the sliding groove, and the positioning device also includes a fixing groove integrally formed on the inner wall of the separation cylinder and capable of cooperating with the fixed block.

[0014] To achieve the above object, the present invention can also adopt the following technical scheme: a method for drying high-nutrition cod puffed crisps, using a high-nutrition cod puffed crisp deoiling drying device, comprising the following steps: Step 1: dismantle the airflow pipe of a high-nutrition codfish puffed crisp de-oiling drying device, take out the placement plate, and perform high-temperature disinfection on the placement plate and the separation plate; Step 2: placing the puffed codfish crisps into a separation plate on a placing plate of a high-nutrition codfish puffed crisp de-oiling and drying device, placing the placing plate with the codfish crisps into a separation cylinder, and positioning and fixing the placing plate by a positioning device; Step 3: Install the airflow tube into the end of the input cylinder and connect it to the airflow pump so that the airflow can enter the separation cylinder from the input cylinder through the airflow tube; Step 4: The drying cylinder rotates at high speed to quickly separate the oil on the cod slices through the centrifugal force of rotation, and the airflow input from the air flow pipe dries and crisps the cod slices; Step 5: Stop the rotating drying drum so that the drying drum after stopping is at the same angle as before starting, remove the air flow tube and the placement plate to obtain the finished cod fish chips.

[0016] The present invention separates the oil on the cod crisps through the centrifugal force generated by the high-speed rotating drying cylinder, and the cod crisps are placed on the separation disk in batches. When rotating at a high speed, a larger air flow rate can be pumped into the air through the air flow pipe to greatly increase the deoiling speed. The separation disk is used to protect the cod crisps, thereby preventing the cod crisps from being blown by the air flow and piling up in large quantities and squeezing each other to cause breakage, so that the finished product has a higher degree of integrity.

[0017] During the process of centrifugal separation of oil and fat of the present invention, after the centrifugal rotation is completed, the oil cleaning device can be quickly pulled at the same time, and the oil in the inner cavity of the separation cylinder can be quickly cleaned through the oil cleaning device after shutdown to prevent the oil from dripping onto the cod crisps again.

The elastic gasket 36 on the separation plate 29 absorbs the pressure brought by the centrifugal force on the cod slices, and cooperates with the side fence 33 to limit the displacement of the cod slices. At the same time, the air holes 34 provided on the side fence 33 allow the air pumped in by the air flow pipe 5 to pass through the air holes 34 and blow on the cod slices to blow away the evaporated and rising fat. After the oil is separated from the cod slices, it will be pressed on the disc body 31 by the centrifugal force, so that the oil enters the oil drain pipe 32, flows along the pipe body 321 of the oil drain pipe 32, and is separated by the diverter plate 323 is used for diversion, and 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 contraction block 324. At this time, the oil can be discharged outward through the gap under the action of centrifugal force. When the rotation stops, the centrifugal force disappears. At this time, the centrifugal block 325 can be pushed up by the return spring 327 to re-close the tube body 321 to avoid oil reflux and keep the dryness and crispness of the de-oiled cod slices. At this time, the separation speed of the oil on the cod slices can be greatly improved, and the airflow pumped in by the airflow pipe 5 can be used to make the cod slices brittle at a high speed, and the de-oiling efficiency is high.
