Abstract
Description
Technical Field
[0001] This patent relates to a fish meat grinding device for crushing and grinding fish meat with bones and fins into fish paste. Background Technology
[0002] To process products such as fish balls, fresh fish meat needs to be crushed and ground into fish paste (or fish slurry).
[0003] CN107136188A discloses a multifunctional fish paste grinding and processing device, including a support, a fixed sleeve, a funnel, a first motor, a first rotating shaft, a first grinding wheel, a second motor, a second rotating shaft, a second grinding wheel, a connecting frame, an electric push rod, a connecting block, a pressure sensor, and a metal sensor. This multifunctional fish paste grinding and processing device has an ingenious structure, powerful functions, and simple operation. By using this device, fish meat can be processed by first extruding and then grinding, so that the fish meat is in a fully ground state. However, due to the use of the first and second grinding wheels, the output per unit time is low, and the processing accuracy requirements of the first and second grinding wheels are very high.
[0004] CN111264602A discloses a compact fish chopper for processing fish balls, including a base. A connecting shaft is rotatably mounted on the side of the power unit near the chopping tank. One end of the connecting shaft passes through the power unit and is connected to a first driven gear. The other end of the connecting shaft is equipped with a fine reamer. A coarse reamer is rotatably mounted on the power unit. One end of the transmission mechanism is connected to the coarse reamer. This design utilizes both fine and coarse reamers, allowing large pieces of fish meat to be first chopped into smaller pieces by the coarse reamer before being chopped by the fine reamer, thus avoiding damage caused by the fine reamer directly impacting the large pieces of fish meat. However, by using only fine and coarse reamers, it is essentially unable to process the fish meat into a finely minced fish paste.

It is easy to use, has high processing efficiency, and the fish meat grinding device has a simple structure, easy parts processing, and no wear on the stationary and moving discs, so it can be used for a long time.
[0007] The technical solution adopted in this patent is as follows:
[0008] A fish grinder has an extruding conveying chamber and a grinding chamber in a casing, the lower part of the grinding chamber has a discharge port, the casing has an inlet port for feeding fish, which is communicated with the extruding conveying chamber; the grinding chamber has a static disc fixed on the casing, a dynamic disc coaxial with the static disc and rotating relative to the static disc under the drive of a grinding power driving device; the central part of the static disc has a plurality of through holes for connecting the extruding conveying chamber and the grinding chamber, the extruding conveying chamber has an extruding device for extruding the fish so that the fish enters the space between the static disc and the dynamic disc through the through holes; the central part of the dynamic disc opposite to the static disc has an arc-shaped blade, the edge part of the static disc opposite to the dynamic disc has grinding edges arranged in the circumferential direction of the static disc and the dynamic disc, and the grinding edges have stoppers arranged in the circumferential direction; when the dynamic disc rotates, the arc-shaped blade pushes the fish entering the space between the central part of the static disc and the dynamic disc to the edge part, and the fish entering the space between the edge part of the static disc and the dynamic disc is ground and then falls through the discharge port.
[0009] The fish grinder has an angle of 10-30° between the grinding edges and the radial direction of the static disc and the dynamic disc.
[0010] The fish grinder has a scraping plate fixed on the outer periphery of the dynamic disc and extending into the space between the outer periphery of the static disc and the casing.
[0011] The fish grinder has a screw auger as the extruding conveying device.
[0012] The fish grinder has the screw auger, one end of which is rotatably supported on the static disc, and the other end of which is connected with an extruding conveying power driving device arranged on the casing; the inlet port is communicated with the upper part of the other end of the screw auger away from the static disc.
[0013] The fish grinder has the screw auger, one end of which is rotatably supported on the static disc, and the other end of which is connected with an extruding conveying power driving device arranged on the casing; the inlet port is communicated with the upper part of the other end of the screw auger away from the static disc.
[0014] The fish grinder has two parallel screw augers, the screw augers have opposite screw directions; the other ends of the two screw augers away from the static disc are connected with two transmission gears engaged with each other, and one of the transmission gears is engaged with a driving gear in the extruding conveying power driving device.
[0015] The fish grinder has a gap of 0.01-0.05mm between the grinding edges on the static disc and the grinding edges on the dynamic disc in the axial direction.
[0016] The fish grinder has the shell comprising the detachably connected shell one and shell two; the static disc is fixed on the shell one, and the extrusion conveying cavity is on the shell one; when the shell one and the shell two are connected together, the shell one and the shell two enclose the grinding cavity; and the dynamic disc is rotatably arranged on the shell two.
[0017] The fish grinder has the end of the grinding edge close to the center part in an inclined shape.
[0018] The fish grinder has the fish with fish bones and fish spines.
[0019] Compared with the prior art, the patent has the following advantages:
[0020] (1) The static disc and the rotating dynamic disc do not contact, and the two are basically not abraded, and can be used for an indefinite period of time.
[0021] (2) The grinding edges on the static disc and the dynamic disc are arranged at intervals, and the relative rotation of the dynamic disc and the static disc causes the fish (including fish bones and fish spines) to continuously enter the grinding edges between the dynamic disc and the static disc from the grooves (including the dynamic grooves and the static grooves) between the grinding edges, and the fish with fish bones and fish spines is repeatedly extruded, torn and ground, until the fish paste (surimi, fish pulp) with a fineness of not more than 200 microns is formed after the fish paste comes out from the edge part between the static disc and the dynamic disc, and then falls from the discharge port.
[0022] (3) The grinding edges on the dynamic disc and the static disc are located at the edge part with a larger area rather than the center part, and the processing efficiency is extremely high, and the dynamic disc and the static disc do not contact, and the rotating speed of the dynamic disc can be higher, so that the yield per unit time can be larger.
[0023] (4) The grinding edges form an angle of 10-30° with the radial direction of the static disc and the dynamic disc, that is, the grinding edges are arranged in a left-handed (counterclockwise) or right-handed (clockwise) manner. The left-handed (counterclockwise) arrangement means that the same grinding edge is counterclockwise from the outer periphery to the center along the radial direction. The right-handed arrangement means that the same grinding edge is clockwise from the outer periphery to the center along the radial direction. When viewed from left to right (or from right to left) along the axial direction, the arrangement direction of the grinding edges on the dynamic disc and the static disc is opposite, and the rotating direction of the dynamic disc is the same as the direction of the grinding edges on the dynamic disc, that is, if the grinding edges on the dynamic disc are arranged in a clockwise manner, the grinding edges on the static disc are arranged in a counterclockwise manner, and the dynamic disc is rotated in a clockwise manner; if the grinding edges on the dynamic disc are arranged in a counterclockwise manner, the grinding edges on the static disc are arranged in a clockwise manner, and the dynamic disc is rotated in a counterclockwise manner. In this way, the fish (including fish bones and fish spines) is better torn and ground under the action of the dynamic disc and the static disc, and is continuously pushed to the edge part.
[0024] (5) The spiral auger belongs to the prior art. The end of the spiral auger close to the static disc is rotatably supported on the static disc, improving the stability of the rotation of the spiral auger, and simplifying the structure.
[0025] (6) The cutting knife can cut off fish meat, fish bones, fish bones, etc. The small fish meat after cutting enters the grinding chamber for better grinding effect.
[0026] (7) The fish bones and fish bones can be ground. When using the device, the fish bones and fish bones are not removed, and the whole fresh fish is removed from the inner organs and fish head. The spiral auger can extrude, transport and preliminarily grind the fish meat with fish bones and fish bones. Through the through hole, it is sent into the grinding chamber for crushing and grinding. The fish meat, fish bones and fish bones are crushed and ground into fish paste (surimi, fish paste). The fish paste is a food, which can not be felt in the mouth. BRIEF DESCRIPTION OF DRAWINGS
