[0002] At present, in the process of batch processing of fish meat, different fish species need to adopt different processing steps and processing methods. The processing of fish meat generally requires the process of cutting, pickling, deodorizing, and packaging. After cutting, it is generally processed by artificial pouring of marinade or other stirring equipment. The most time-consuming part is pickling. The pickling time generally takes at least 5 hours to taste and ensure the shelf life. Artificial pickling not only has high labor costs, but is difficult to catch up with the speed of machine processing, affecting the freshness of meat in time and low processing efficiency. When other stirring equipment is used, the marinade can be sufficient, but the meat is still not good in taste and taste. In the processing process, the most important issue for the quality of fish processing is time. High-quality pickled fish products are to ensure fast processing when fresh fish is fresh to prevent meat rot and ensure freshness. The processing of golden pomfret has fewer bones and the fish meat is fresh and tender, which is deeply loved by people. Its processing method needs a fast and efficient taste processing. Therefore, a new pickling device with automatic heating, spraying, cutting, and conveying is provided, and a pickling processing method for golden pomfret based on the device is provided.

[0014] A method for pickling golden pomfret based on the above-mentioned fish pickling device comprises the following steps:

[0015] S1. Place the cleaned golden pomfret on the placement table, and the telescopic rod drives the adjustment plate to move, and then drives the pressing plate to move vertically downward through the connecting rod and the control rod until the bottom surface of the conveyor belt in the pressing plate contacts the fish;

[0016] S2, while the adjusting plate moves, the push rod pushes the piston member 1 in the piston tube 1, thereby allowing the air in the transmission groove to enter the piston tube 2, so that the piston member 2 drives the clamping plate to clamp the fish and limit the position of the fish;

The outer peripheral surface of the eccentric wheel contacts the lifting plate, thereby driving the salted powder cutting knife as a whole to move up and down along the support rod, so that the knife head cuts or chops the fish. At the same time, the hot air of the hot air blower heats the knife head to quickly dry the surface of the cut fish meat and lock in freshness;

[0018] S4. While the knife head is cutting or chopping, the hot air blower blows the marinade powder in the marinade box and disperses it into the air in the marinade box, and the micro air pump sprays the air with the marinade powder into the hollow part of the knife body through the telescopic tube, and then sprays it on the cut fish meat and the surface fish skin on both sides of the knife head through the spray holes on both sides of the knife head. At the same time, the hot air from the hot air blower further dehumidifies and dries the fish meat.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The processing device of the present invention adopts an internally hollow marinating powder cutting integrated knife, which is connected to the marinating powder cutting integrated knife through a marinating box. When cutting the fish meat, the hot air blower lifts the marinating powder in the marinating box, and cooperates with a micro air pump to spray air with the marinating powder into the hollow part of the knife body, and then sprays the air onto the cut fish meat or fish skin on both sides through the spray holes on both sides of the knife head, so that the cutting of the marinating powder is completed in one piece, and the marinating powder is placed in the interior of the fish meat, which effectively improves the marinating processing efficiency of the fish meat. At the same time, a heating plate is provided on the knife head, and the knife head is heated by the heating plate to always maintain a certain high temperature, so that the cut cross section can be quickly dried and locked while cutting the fish meat. Fresh, with the hot air generated by the hot air blower, the surface of the fish meat and fish skin is auxiliary heated and air-dried, reducing the loss of internal moisture in the fish meat when it is placed for pickling, locking the freshness of the fish meat, and thus achieving effective preservation and rapid pickling; a stepper motor is used in conjunction with an eccentric wheel to drive the salting powder cutting integrated knife to cut the fish meat, and the height position of the salting powder cutting integrated knife can be adjusted by adjusting the angle of each rotation of the stepper motor, thereby achieving the effect of completely cutting the fish meat or incompletely cutting and changing the knife, and at the same time controlling the number of knife cuts to achieve the chopping of the fish meat, further improving the flexibility of the fish meat for different processing or different fish processing needs;

[0021] A limiting mechanism is installed on the adjustment plate. When the pressing plate is pressed down and the adjustment plate moves, the piston movement among the piston tube 1, the piston member 1, the transmission groove, the piston tube 2 and the piston member 2 makes the clamping plate limit and align the position of the fish when the conveyor belt contacts the fish meat, thereby preventing the fish from rotating or shifting in angle, and facilitating subsequent cutting or chopping.

[0022] The method for quickly pickling golden pomfret of the present invention realizes effective and quick pickling of fish meat, greatly reduces the pickling time, and simultaneously performs surface drying, freshness locking and cutting of the fish meat during pickling, effectively realizing the freshness-preserving processing of the golden pomfret meat, and can realize integrated processing of conveying, cutting, chopping meat and spraying pickling materials, effectively improving processing efficiency and processing quality.

[0038] A method for pickling golden pomfret based on the above-mentioned fish pickling device comprises the following steps:

[0039] S1. Place the cleaned golden pomfret on the placement table 1, and the telescopic rod 15 drives the adjustment plate 16 to move, and then drives the pressing plate 10 to move vertically downward through the connecting rod 17 and the control rod 18 until the bottom surface of the conveyor belt 14 in the pressing plate 10 contacts the fish;

[0040] S2. While the adjusting plate 16 is moving, the push rod 28 pushes the piston member 1 27 in the piston tube 1 26, thereby allowing the air in the transmission groove 25 to enter the piston tube 2 29, so that the piston member 2 30 drives the clamping plate 21 to clamp the fish, thereby limiting the position of the fish;

[0041] S3, the heating plate 38 heats the knife head 35 to keep the knife head 35 at a certain high temperature. When the fish is transported to the bottom of the salted powder cutting knife 7, the telescopic rod 15 is reset, thereby driving the pressing plate 10 and the clamping plate 21 to reset, and the stepper motor drives the eccentric wheel 22 to rotate. The outer peripheral surface of the eccentric wheel 22 contacts the lifting plate 33, thereby driving the salted powder cutting knife 7 to move up and down along the support rod 23 as a whole, so that the knife head 35 cuts or chops the fish. At the same time, the heated knife head 35 can quickly dry the surface of the cut or chopped fish meat to lock in freshness;

[0042] The stepper motor cooperates with the eccentric wheel to drive the salted powder cutting integrated knife to cut the fish meat. The height position of the salted powder cutting integrated knife can be adjusted by adjusting the angle of each rotation of the stepper motor, so as to achieve the effect of complete cutting of the fish meat or incomplete cutting and changing the knife. At the same time, the number of knife cuts can be controlled to achieve the chopping processing of the fish meat. When the golden pomfret is pickled, 15 short-distance light cuts are used, and then 1 heavy cut is used.

[0043] S4. During the cutting or chopping process of the cutter head 35, the hot air blower 37 works to blow the marinade powder in the marinade box 8 and disperse it into the air in the marinade box 8, and the micro air pump 39 works to spray the air with the marinade powder into the hollow part of the cutter body 34 through the telescopic tube 9. During each cutting, the marinade powder is sprayed on the cut fish meat and the surface fish skin on both sides of the cutter head 35 through the spray holes 36 on both sides of the cutter head 35. At the same time, the hot air from the hot air blower 37 further dehumidifies and dries the fish meat to lock in freshness.

[0044] After testing, the same amount of golden pomfret was pickled at the same time. A method using manual pickling and a mixer and a method using the present device for the pickling process were compared. The pickling time was reduced by 75%. At the same time, the golden pomfret pickled by the present device had a sweeter taste and a stronger golden pomfret gelatin flavor.

[0045] The present invention realizes the chopping, slitting, heating and marinating spraying pickling processing of golden pomfret meat, which greatly reduces the pickling time. At the same time, the surface of the fish meat is dried, the freshness is locked, and the chopping and slitting are performed during the pickling process, thereby effectively realizing the fresh-keeping processing of the golden pomfret meat. Moreover, the integrated processing of conveying, slitting, chopping and spraying marinating can be realized, thereby effectively improving the efficiency of processing golden pomfret.
