[0049] A cooling process for fish intestine production and processing is used by using the cooling device for fish intestine production and processing, and includes the following steps:

[0050] S1: The cooling chamber 2 is erected outside the plate chain conveyor body 1 through the frame 4 and the supporting beam 5; the spray hard pipe 8 is hung on the inner side top wall of the cooling chamber 2 through the top rod 10, and one end of the spray hard pipe 8 is communicated with the water inlet device outside;

[0051] S2: The plate chain conveyor body 1 is started, the placing tray 7 carrying the fish intestines is sent into the cooling chamber 2, the cooling fan 3 is started and runs at a set wind speed through the controller 9, and the fish intestines are cooled;

[0052] S3: In the cooling process, the casing of the fish intestines is moistened by spraying the cooling chamber 2 through the atomizing nozzle 21 on the spray hard pipe 8, so that the casing is prevented from being dry and cracked in the cooling environment;

[0053] S4: The motor 11 is started to drive the ball screw 20 to rotate, the sliding seat 16 is driven to reciprocate along the sliding rod 18 and the ball screw 20, the hydraulic rod 13 is controlled to extend and retract, the sleeve disc 22, the guide rod 23 and the guide ring 33 are driven to move through the L-shaped frame 15, the guide ring 33 is driven to move through the connecting block 24 and the connecting arm 25 to push the abutment 26 and the rubber block 27, the sliding ring 28 is driven to slide along the outside of the extension rod through the guide plate 29 and the connecting rod 31, the rotating sleeves 32 and the flexible fingers 30 on the clamping barrel 19 are driven to reciprocate, the fish intestines in the placing tray 7 are gently pushed to prevent adhesion;

[0054] S5: The condensed water generated in the cooling process is concentrated and discharged through the drain pipe 6 at the bottom of the cooling chamber 2.

[0055] Working principle: when the present application works, first, through the frame 4 of the mounting and the support beam 5, the cooling chamber 2 is stably erected outside the plate chain conveyor main body 1, ensuring that the cooling chamber 2 and the conveying path are in the same direction, then through the top rod 10 of the suspension mechanism, the spray hard pipe 8 is horizontally suspended on the inside top wall of the cooling chamber 2, so that one end of the spray hard pipe 8 extends to the outside of the cooling chamber 2 and is in sealed communication with the external water inlet device, ensuring stable atomization water supply, at the same time, when the fish intestine on the loading tray 7 does not enter the cooling chamber 2, the flexible finger lever 30 of the anti-sticking mechanism is initially in the high position, avoiding interference with the conveyor or the loading tray 7;

[0056] The cooling operation starts inside the cooling chamber 2, the plate chain conveyor main body 1 starts to run smoothly, and the loading tray 7 carrying the hot processed fish intestine is stably conveyed into the cooling chamber 2, until the loading tray 7 completely enters the cooling area, the conveyor keeps uniform forward state, ensuring that the fish intestine is in continuous cooling process, at the same time, through the controller 9 on the outer wall of the cooling chamber 2, three cooling fans 3 are started, according to the fish intestine specifications such as diameter, length and casing type, the output air speed of the cooling fan 3 is adjusted to the appropriate gear, the cooling fan 3 generates cold air from top to bottom, evenly blowing the surface of the fish intestine, quickly taking away the heat of the fish intestine, realizing rapid temperature drop; the external water inlet device is started at the same time, the water flow is distributed to multiple atomizing nozzles 21 through the spray hard pipe 8, the atomizing nozzles 21 atomize the water flow into water mist, which is evenly sprayed on the surface of the fish intestine casing, forming a thin water film, making up for the water evaporation caused by direct blowing of cold air, avoiding the shrinkage and dry cracking of the casing due to rapid loss of water, realizing the synchronous operation of cooling and moisturizing and preventing cracking;

[0057] In the cooling and moisturizing process, the reciprocating mechanism and the anti-sticking mechanism cooperate to solve the sticking problem of fish intestines during cooling and shrinkage. Specifically, the rotation of the motor 11 drives the ball screw 20 to rotate along the rail frame 14. Since the sliding seat 16 is threadedly connected with the ball screw 20 and is slidingly limited with the sliding rod 18, the rotary motion of the ball screw 20 is converted into the reciprocating linear motion of the sliding seat 16 along the length direction of the sliding rod 18 and the ball screw 20. During the movement, the hydraulic rods 13 at both ends of the sliding seat 16 are controlled to extend and retract synchronously. The extending and retracting ends of the hydraulic rods 13 push the L-shaped frame 15 to move downward, and the L-shaped frame 15 drives the sleeve disc 22 to move downward synchronously. The sleeve disc 22 pulls the guide ring 33 to slide along the guide rod 17 stably through the guide rod 23. The connecting block 24 on the outer wall of the sleeve disc 22 pulls the resistance frame 26 through the connecting arm 25, and then pushes the sliding ring 28 to slide horizontally along the extension rod of the guide rod 17. The sliding ring 28 drives the connecting rod 31 to move synchronously through the folding plate 29, and finally makes the flexible finger 30 on the outer side of the rotating sleeve 32 close to the surface of the fish intestines in the placement tray 7. Through the reciprocating movement from top to bottom to both sides, when the flexible finger 30 contacts the fish intestines, the rotating sleeve 32 can rotate freely along the cartridge 19, converting the sliding friction between the flexible finger 30 and the fish intestines into rolling friction. In combination with the soft material property of the flexible finger 30, the fish intestines are gently pushed to make a small displacement in the placement tray 7 without damaging the fish intestines. At the same time, the reciprocating movement of the sliding seat 16 drives the flexible finger 30 to cover the entire area of the placement tray 7, effectively breaking the adsorption force between the fish intestines and the inner wall of the placement tray 7 due to cooling and shrinkage, completely avoiding the sticking phenomenon, and ensuring that each fish intestine is in a complete state.

[0058] During the cooling process, the part of the atomized water mist that has not been completely evaporated will condense into condensed water, flow down along the inner wall of the cooling chamber 2, and finally collect at the bottom of the cooling chamber 2. The condensed water is discharged to the outside through the drain pipe 6 connected at the bottom, avoiding the accumulation of condensed water in the cooling chamber 2, which may cause bacterial growth or affect the cooling effect.

[0059] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.

A cooling process for fish intestine production and processing, using the cooling device for fish intestine production and processing described in claim 3, characterized in that, Includes the following steps: S1: The cooling chamber (2) is erected outside the main body (1) of the plate chain conveyor through the frame (4) and the support beam (5); the spray hard pipe (8) is suspended on the inner top wall of the cooling chamber (2) through the top rod (10), and one end of it is connected to the external water inlet device; S2: Start the main body of the plate chain conveyor (1), send the tray (7) carrying the fish intestines into the cooling chamber (2), start the cold air fan (3) through the controller (9) and run it at the set wind speed to cool the fish intestines; S3: During the cooling process, the casing of the fish intestine is moistened by spraying the atomizing nozzle (21) on the spray hard pipe (8) into the cooling chamber (2) to prevent the casing from drying and cracking in the cooling environment; S4: Start the motor (11) to drive the ball screw (20) to rotate, which drives the slide (16) to reciprocate along the slide rod (18) and the ball screw (20). At the same time, control the extension and retraction of the hydraulic rod (13). Through the L-shaped frame (15), drive the sleeve (22), guide rod (23), and guide ring (33) to move. The movement of the guide ring (33) pushes the abutment (26) and rubber block (27) through the connecting block (24) and connecting arm (25), so that the slip ring (28) slides along the outside of the extension rod. The slip ring (28) drives the roller brush to move through the folding plate (29) and connecting rod (31), so that the rotating sleeve (32) and flexible finger rod (30) on the caliper (19) swing back and forth, gently pushing the fish intestine in the storage tray (7) to prevent it from sticking together. S5: The condensate generated during the cooling process is discharged through the drain pipe (6) at the bottom of the cooling chamber (2).
