[0018] As Figures 1-3 shown, a fish soluble paste enzymolysis device includes a cylinder body 1 which is hollow inside. A feed inlet 2 is opened at the upper part of the cylinder body 1. A feed baffle plate 21 is hinged in the feed inlet 2. A medium cavity 3 is arranged inside the side wall of the cylinder body 1 for storing liquid heat preservation medium. It also includes an electric heating rod 4, a propulsion and circulation mechanism 5 and a circulation and heat preservation mechanism 6. The electric heating rod 4 is arranged inside the medium cavity 3. The propulsion and circulation mechanism 5 is rotatably arranged at the center inside the cylinder body 1 for pushing the fish soluble paste to flow and pushing it from top to bottom and from the center to the outside of the cylinder body 1. The circulation and heat preservation mechanism 6 is arranged on the outer side wall of the cylinder body 1 for the medium to circulate and flow, so that the cylinder body 1 maintains a constant temperature.
[0019] As Figure 2 and Figure 3 shown, in order to increase the circulation and flow of the fish soluble paste inside the cylinder body 1 and make the added degradation enzyme mix evenly with the fish soluble paste, the circulation and propulsion mechanism includes a rotating motor 7, a rotating shaft 8, a screw blade 9 and a baffle plate 10. The rotating motor 7 is arranged at the center of the upper wall of the cylinder body 1. One end of the rotating shaft 8 is fixedly connected to the output end of the rotating motor 7. The other end of the rotating shaft 8 is rotatably arranged at the center of the inner bottom wall of the cylinder body 1. The screw blade 9 is wound around the outer side wall of the upper part of the rotating shaft 8. The baffle plate 10 is fixedly connected to the outer side wall of the lower part of the rotating shaft 8. The outer side wall of the baffle plate 10 is provided with a flared opening from top to bottom. The rotating motor 7 drives the rotating shaft 8 to rotate, so that the screw blade 9 and the baffle plate 10 rotate synchronously. The screw blade 9 pushes the fish soluble paste to flow downward and impacts the baffle plate 10. The fish soluble paste flows along the outer side wall of the baffle plate 10 and gradually disperses from the center to the outside, hitting the inner side wall of the cylinder body 1. With the continuous pushing of the subsequent fish soluble paste, the fish soluble paste circulates from top to bottom and from the center to the outside inside the cylinder body 1, making the fish soluble paste mix evenly with the degradation enzyme and increasing the fluidity of the fish soluble paste.
[0020] As Figure 2 and Figure 3As shown in the figure, in order to achieve constant temperature of fish soluble paste and maintain enzymatic hydrolysis activity, medium water is added into the medium cavity 3 inside the side wall of the cylinder body 1. The circulation heat preservation mechanism 6 includes a water pump 11 and a connection box 12. The connection box 12 is fixedly connected to the bottom edge of the cylinder body 1. The water pump 11 is fixedly connected to the bottom wall of the connection box 12. The water outlet end of the water pump 11 is communicated with the inside of the connection box 12. An inlet pipe 13 is connected between the water pumping end of the water pump 11 and the bottom of the outer side wall of the cylinder body 1. A circulation pipe 14 is connected between the side wall of the connection box 12 and the upper wall of the cylinder body 1. The medium at the bottom of the medium cavity 3 is pumped through the inlet pipe 13 to the upper end of the cylinder body 1 for the flow of the medium. After the electric heating rod 4 is started, the medium in the medium cavity 3 is heated up. At the same time, the inlet pipe 13 connected to the water pump 11 is driven to pump the medium at the bottom of the medium cavity 3. The water pump 11 is a high-temperature water pump 11, which is suitable for pumping high-temperature liquids. It circulates from the upper part of the medium cavity 3 through the connection box 12 and the circulation pipe 14, realizing the circulating flow of the medium in the medium cavity 3 and keeping the medium evenly at a constant temperature.
[0021] As Figures 2-4 shown in the figure, in order to increase the fluidity of the fish soluble paste inside the cylinder body 1 and avoid impurities from depositing at the bottom of the cylinder body 1, a pressure cavity 15 is opened inside the bottom wall of the cylinder body 1. An air pump 16 is provided at the center of the bottom wall of the cylinder body 1. The air outlet end of the air pump 16 is communicated with the pressure cavity 15. Through holes 17 are opened on the inner bottom wall of the cylinder body 1. The through holes 17 are arranged in an array at equal intervals. Rubber valves 18 are provided in the through holes 17. The air pump 16 pumps external air into the pressure cavity 15, squeezing the rubber valves 18 to extrude air bubbles through the array of through holes 17, impacting the fish soluble paste upward and increasing the fluidity of the fish soluble paste.
[0022] Among them, a discharge pipe 19 is connected through the side wall of the cylinder body 1 to communicate with the medium cavity 3. A solenoid valve 20 is provided at the port of the discharge pipe 19, and the discharge of the discharge pipe 19 is controlled by the opening and closing of the solenoid valve 20.
[0023] During specific use, the operator opens the feed baffle 10, adds fish soluble paste into the barrel body through the feed port 2, disassembles the inlet pipe 13 to pump external medium water into the medium cavity 3. When the medium inside the medium cavity 3 is filled to the same height as the liquid level of the fish soluble paste, the inlet pipe 13 is connected to the outer side wall of the cylinder body 1, so that the inlet pipe 13 and the circulation pipe 14 form a circulation outside the medium cavity 3, and the electric heating rod 4 is powered on to uniformly increase the medium temperature;
[0024] The rotation motor 7 is started to drive the rotation of the rotating shaft 8, so that the spiral blade 9 and the baffle 10 rotate synchronously. The spiral blade 9 pushes the fish soluble paste to flow downward and impacts the baffle 10. The fish soluble paste gradually disperses from the center to the outside along the outer side wall of the baffle 10 and impacts the inner side wall of the cylinder body 1. With the continuous pushing of the subsequent fish soluble paste, the fish soluble paste circulates from top to bottom and from the center to the outside inside the cylinder body 1, making the fish soluble paste mix evenly with the degradation enzyme and increasing the fluidity of the fish soluble paste;
[0025] Meanwhile, the air pump 16 extracts external air into the pressure chamber 15, squeezing the rubber valve 18 to extrude air bubbles through the array of through-holes 17, impacting the fish soluble paste upward, increasing the fluidity of the fish soluble paste, and maintaining the fluidity of the fish soluble paste.
[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
