Description

Technical Field

[0001] This invention relates to the field of surimi production technology, specifically to an automatic water-adding device and method for surimi production. Background Technology

[0002] In the production of surimi products, surimi is the core raw material, and its quality directly affects the quality of the final product. In traditional surimi production processes, it is difficult to control the amount of water added during the mixing of surimi and water.

[0003] Previously, workers relied on their experience to roughly determine whether water needed to be added by visually observing the appearance of the fish paste or simply by touching it. This subjective judgment method had a large margin of error. Due to the lack of precise testing methods, it was impossible to know the exact moisture content of the fish paste in real time. If too much water was added, the excess water would seep out during subsequent processing, affecting product shaping and potentially breeding microorganisms, thus shortening the product's shelf life. On the other hand, if too little water was added, the fish paste would lack viscosity, making it difficult to process and shape, which would also reduce product quality.

[0004] With consumers' increasing demands for the quality of surimi products and the growing need for large-scale and standardized production in the food industry, it is necessary to provide an automatic water-adding device and a method for adding water to surimi to meet the need for precise water addition during the mixing and processing of surimi.

[0009] A feed port is provided on the side cover of the middle part of the detection channel, and a discharge port is provided on the side cover of the bottom part of the detection channel. Both the feed port and the discharge port penetrate the side of the mixing drum.

[0010] The bottom end of the side cover is provided with a sealing column, and the outside of the mixing cylinder is fixedly provided with a bottom mounting base. The top end of the bottom mounting base is fixedly connected with a lower hydraulic telescopic rod, and the telescopic end of the lower hydraulic telescopic rod is fixedly connected to the sealing column.

[0011] The upper part of the side cover is provided with an upper hydraulic telescopic rod, the telescopic end of which is fixedly connected to a pressure rod, and the pressure rod is fixedly connected to the top end of the pressure sleeve.

[0012] The pressure sleeve is equipped with a displacement detection component, which includes a filter screen embedded in the bottom of the pressure sleeve. A lifting block is slidably connected inside the pressure sleeve. A lifting guide post is fixedly connected to the top of the lifting block. The lifting guide post passes through the top of the pressure sleeve and is fixedly connected to a top block. The top block is fixedly connected to a conductive sleeve. The conductive sleeve is disposed outside the pressure rod and slidably connected thereto. An induction coil corresponding to the conductive sleeve is provided outside the pressure rod.

[0013] As a preferred embodiment of the present invention, the bottom end of the chassis is fixedly provided with a plurality of support legs.

[0014] As a preferred embodiment of the present invention, the stirring and mixing mechanism includes a drive motor fixedly mounted on the bottom of the chassis, the output shaft of the drive motor extending into the stirring drum and coaxially fixedly connected to the stirring shaft, and a plurality of stirring rods fixedly mounted on the outside of the stirring shaft.

[0016] As a preferred embodiment of the present invention, a return spring is fixedly connected between the top block and the top of the pressure sleeve.

[0017] As a preferred embodiment of the present invention, the top of the mixing drum is provided with a feed hopper, the bottom of the mixing drum is fixedly provided with a discharge pipe, and the discharge pipe is provided with a discharge valve.

[0018] As a preferred embodiment of the present invention, the water adding mechanism includes a water adding cover fixedly installed at the top of the mixing drum, and a water pump is provided inside the water adding cover, with the output end of the water pump extending into the mixing drum.

[0020] A method for adding water to fish surimi using an automatic water-adding device in fish surimi production includes the following steps:

[0021] Step 1: Premixing. After crushing the fish paste raw material, add it into the mixing drum through the feeding hopper. Then, control the water adding mechanism to deliver water into the mixing drum, and control the mixing mechanism to mix the fish paste raw material and water.

[0022] Step 2: Meat content detection of fish paste. Control the upper hydraulic telescopic rod to retract and move the pressure sleeve upward, opening the feed side port. The fish paste enters the detection channel through the feed side port. Then, control the upper hydraulic telescopic rod to move the pressure sleeve downward continuously. The pressure sleeve closes the feed side port on one hand and squeezes the fish paste on the other. The water in the fish paste enters the pressure sleeve through the filter screen, pushing the sealing column upward. The sealing column drives the lifting guide column, top block and conductive sleeve to move synchronously. The conductive sleeve slides outside the pressure rod. The volume of water in the pressure sleeve and the moisture content of the fish paste can be calculated based on the position where the conductive sleeve stops after sliding outside the pressure rod.

[0023] Step 3: After the material is discharged, control the lower hydraulic telescopic rod to retract, causing the sealing column to move down and open the discharge side opening. Control the upper hydraulic telescopic rod to continue extending, causing the pressure sleeve to continue moving down and pushing the fish paste out of the discharge side opening. Under the action of the return spring, the lifting block will push out the water in the pressure sleeve. Then, first control the lower hydraulic telescopic rod to reset and close the discharge side opening, and then control the upper hydraulic telescopic rod to reset, completing the single fish paste moisture content detection work.

[0024] Step 4: Based on the measured water content data of the fish paste, if the water content exceeds the standard, continue to add the crushed fish paste raw material into the mixing drum. If the water content is insufficient, control the water pump to start and automatically add water into the mixing drum according to the water content data.

[0025] The present invention has the following advantages: by setting a mixing mechanism in the mixing drum, the present invention can fully mix the surimi raw material and water. By setting a surimi moisture content detection mechanism, the mixed surimi can be sampled and the moisture content of the surimi can be detected. Based on the moisture content of the surimi, the method of not adding water or automatically adding water can be selected. During the surimi production process, the surimi can maintain a good moisture content, thereby ensuring product quality. Attached Figure Description

[0036] Please see Figure 1-7 An automatic water-adding device for surimi production includes a mixing drum 1, a base plate 2 fixedly connected to the bottom end of the mixing drum 1, and multiple support legs 3 fixedly provided at the bottom end of the base plate 2.

[0037] The mixing drum 1 is equipped with a mixing mechanism for mixing the fish paste raw material and water. The fish paste raw material is a product made by crushing fish meat and fish bones. The side of the mixing drum 1 is equipped with a fish paste moisture content detection mechanism for detecting the moisture content in the fish paste. The top of the mixing drum 1 is equipped with a water adding mechanism. When the moisture content of the fish paste is too high, fish paste raw material is added to reduce the moisture content.

[0038] The fish paste moisture content detection mechanism includes a side cover 9 fixedly installed on one side of the mixing drum 1. The side cover 9 has a detection channel, and a pressure sleeve 16 is slidably connected in the detection channel. The pressure sleeve 16 passes through the top of the side cover 9.

[0041] The upper hydraulic telescopic rod 8 is provided above the side cover 9. The telescopic end of the upper hydraulic telescopic rod 8 is fixedly connected to the pressure rod 17, and the pressure rod 17 is fixedly connected to the top end of the pressure sleeve 16.

[0042] The pressure sleeve 16 is provided with a displacement detection component 23. The displacement detection component 23 includes a filter screen 24 embedded in the bottom of the pressure sleeve 16. A lifting block 25 is slidably connected inside the pressure sleeve 16. A lifting guide post 26 is fixedly connected to the top of the lifting block 25. The lifting guide post 26 passes through the top of the pressure sleeve 16 and is fixedly connected to a top block 27. The top block 27 is fixedly connected to a conductive sleeve 29. The conductive sleeve 29 is disposed outside the pressure rod 17 and is slidably connected thereto. An induction coil corresponding to the conductive sleeve 29 is provided outside the pressure rod 17.

[0043] Specifically, a controller can be installed outside the stirring drum 1. The controller is electrically connected to the conductive sleeve 29 and the induction coil to obtain the position of the conductive sleeve 29 outside the pressure rod 17. The circuit for obtaining the position between the conductive sleeve and the induction coil can use a circuit module from the prior art.

[0044] The mixing mechanism includes a drive motor 11 fixedly mounted on the bottom of the chassis 2. The output shaft of the drive motor 11 extends into the mixing drum 1 and is coaxially fixedly connected to the mixing shaft 12. Multiple mixing rods 13 are fixedly mounted on the outside of the mixing shaft 12.

[0045] A lifting cover 14 is fixedly installed at the bottom of the mixing drum 1. A spiral lifting plate 15 is installed inside the lifting cover 14. The spiral lifting plate 15 is coaxially fixedly connected to the mixing shaft 12. A fish paste passage groove is provided at the bottom of the lifting cover 14.

[0046] A return spring 28 is fixedly connected between the top block 27 and the top of the pressure sleeve 16.

[0047] The top of the mixing drum 1 is provided with a feed hopper 4, and the bottom of the mixing drum 1 is fixedly provided with a discharge pipe 10, which is provided with a discharge valve.

[0048] The water addition mechanism includes a water addition cover 5 fixedly installed at the top of the mixing drum 1. A water pump is installed inside the water addition cover 5, and the output end of the water pump extends into the mixing drum 1.

[0049] A top rod 6 is fixedly installed at the top of the mixing drum 1, and a top plate 7 is fixedly connected to the top of the top rod 6. The upper hydraulic telescopic rod 8 is fixedly connected to the top plate 7.

[0050] When the above-mentioned automatic water-adding equipment for surimi production adds water to the surimi, it first performs a pre-mixing operation. After crushing the surimi raw material, it adds it to the mixing drum 1 through the feed hopper 4. Then, it controls the water-adding mechanism to deliver water to the mixing drum and controls the mixing mechanism to mix the surimi raw material and water.

[0051] Then, the moisture content of the fish paste is tested. The upper hydraulic telescopic rod 8 is controlled to retract, which drives the pressure sleeve 16 to move upward, opening the feed side port 18. The fish paste enters the testing channel through the feed side port 18. Then, the upper hydraulic telescopic rod 8 is controlled to drive the pressure sleeve 16 to move downward continuously. The pressure sleeve 16 closes the feed side port 18 on the one hand, and squeezes the fish paste on the other hand. The water in the fish paste enters the pressure sleeve 16 through the filter screen 24, pushing the sealing column 22 upward. The sealing column 22 drives the lifting guide column 26, the top block 27 and the conductive sleeve 29 to move synchronously. The conductive sleeve 29 slides outside the pressure rod 17. The volume of water in the pressure sleeve 16 and the moisture content of the fish paste can be calculated based on the position where the conductive sleeve 29 stops after sliding outside the pressure rod 17.

[0052] Next, the tested fish paste is discharged, the lower hydraulic telescopic rod 21 is retracted, which drives the sealing column 22 to move down and open the discharge side port 19. The upper hydraulic telescopic rod 8 is extended, which drives the pressure sleeve 16 to move down and push the fish paste out of the discharge side port 19. Under the action of the return spring 28, the lifting block 25 pushes out the water in the pressure sleeve 16. Then, the lower hydraulic telescopic rod 21 is reset to close the discharge side port 19, and the upper hydraulic telescopic rod 8 is reset to complete the single fish paste moisture content test.

[0053] Finally, based on the measured water content data of the fish paste, if the water content exceeds the standard, the crushed fish paste raw material will continue to be added to the mixing drum 1; if the water content is insufficient, the water pump will be started according to the water content data to automatically add water to the mixing drum 1.

[0054] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
