Description

Technical Field

[0001] The utility model relates to the technical field of aquatic feed production, in particular to an aquatic feed puffing device. Background Technique

[0002] With the development of China's aquatic aquaculture industry towards regularization and large-scale production, the requirements for aquatic feed are getting higher and higher. On the one hand, attention should be paid to grasping the content of each nutrient component in the feed. On the other hand, the puffing process of the feed should be strictly controlled to help fish or shrimp better ingest and digest the feed, thereby increasing the yield.

[0003] To improve the quality of feed, a feed puffing machine is used in the production of aquatic feed. During the puffing process, the feed raw materials will be treated under high temperature and high pressure, making the internal structure of the feed particles loose and porous. In this way, it is beneficial to the penetration of moisture and enzymes, improving the digestibility and stability of the feed. However, since the working principle of the puffing machine is to convert mechanical energy into heat energy, and the food is extruded and cooked by the heat generated by the rotation of the machine, thereby increasing the volume of the food. The puffing process involves complex processes such as high temperature and high pressure, and water evaporation. Therefore, steam will be discharged during the discharging process, and after the water vapor scatters, it will come into contact with the puffing machine itself and the surrounding equipment, resulting in the accelerated aging of the puffing machine itself and the surrounding equipment. For this reason, an aquatic feed puffing device is proposed. Summary of the Utility Model

[0004] Based on the above description, the utility model provides an aquatic feed puffing device, which solves the problem that when using the existing feed puffing machine to produce aquatic feed, due to the lack of steam treatment during discharging, it is easy to cause the accelerated aging of the factory equipment.

[0006] A bracket, which is erected on the ground and supports the puffing body;

[0007] A steam treatment mechanism, which includes a machine cover and a cooling water tank arranged in parallel on the bracket, as well as a heat exchange tube and a drainage component. Among them, the heat exchange tube is placed in the cooling water tank and is spiral. One end of the heat exchange tube is connected to the machine cover through the drainage component, and the other end is provided with an outlet pipe passing through one side of the cooling water tank. The drainage component is installed on the machine cover. When the steam is drained through the drainage component, the steam at the discharging port of the puffing body will pass through the heat exchange tube, enabling this steam to be converted into liquid through heat exchange and cooling means.

[0008] On the basis of the above technical solution, the utility model can also be improved as follows.

[0009] Further, the cooling water tank has an upper opening to connect the space inside the cooling water tank with the outside. The liquid in the cooling water tank is water. The spiral diameter of the heat exchange tube increases sequentially from top to bottom and is immersed in the water.

An inlet pipe penetrating into the hood is arranged at the inlet end of the suction fan, and a conduction pipe communicating with the heat exchange tube is arranged at the outlet end of the suction fan.

[0011] Further, a refrigeration component is also included. The refrigeration component is arranged on one side of the cooling water tank and is used to cool the liquid in the cooling water tank.

[0012] Further, the refrigeration component includes a thermoelectric cooler. The thermoelectric cooler is detachably connected to one side of the cooling water tank. A cold guide plate located in the cooling water tank is arranged at the cold end of the thermoelectric cooler to cool the liquid in the cooling water tank, and a fan is arranged at the hot end of the thermoelectric cooler.

[0016] Further, the bracket is composed of four groups of legs and a support plate, and the four groups of legs are symmetrically distributed in pairs at the bottom of the support plate.

[0017] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0026] In the prior art, since the working principle of a feed puffing machine is to convert mechanical energy into heat energy, and the food is extruded and cooked by the heat generated by the rotation of the machine, thereby increasing the volume of the food, and the puffing process involves complex processes such as high temperature and high pressure and water evaporation, steam will be discharged during the discharging process.

[0027] To prevent the steam from dispersing and contacting the puffing machine itself and its surrounding equipment, and to prevent the accelerated aging of the puffing machine itself and its surrounding equipment in the factory due to steam, this application designs an aquatic feed puffing device, as Figure 1As shown in the figure, an aquatic feed puffing device in this embodiment includes a puffing body 1, a bracket 2, and a steam treatment mechanism 3. The puffing body 1 is a feed puffing machine in the prior art, mainly used for making aquatic feed, and its structure will not be elaborated here. The bracket 2 is erected on the ground and provides a support surface for the puffing body 1 and the steam treatment mechanism 3, that is, the bracket 2 supports the puffing body 1 and the steam treatment mechanism 3. As for the steam treatment mechanism 3, it is used for guiding and heat-exchanging and cooling the steam, avoiding the dispersion of the steam, and converting the steam into liquid, so as to reduce the accelerated aging of the aquatic feed puffing device itself and its surrounding equipment.

[0028] It should be noted that the bracket 2 is composed of four sets of legs and a support plate. The four sets of legs are symmetrically distributed in pairs at the bottom of the support plate, and the above-mentioned puffing body 1 and steam treatment mechanism 3 are both arranged on this support plate.

[0029] To facilitate understanding of how the steam treatment mechanism 3 completes the above-mentioned guiding and heat-exchanging and cooling treatment, the position and structure of the steam treatment mechanism 3 are described correspondingly here. Specifically, as Figures 1-4 shown, the steam treatment mechanism 3 includes a machine cover 31, a cooling water tank 32, a heat exchange tube 33, and a guiding component. The machine cover 31 and the cooling water tank 32 are arranged side by side on the bracket 2 and are both detachably connected to the bracket 2 by bolts. There is an inner space in the cooling water tank 32. In this way, the heat exchange tube 33 can be placed in the cooling water tank 32, and the inner space stores liquid for subsequent heat-exchanging and cooling. One end of the heat exchange tube 33 is connected to the machine cover 31 through the guiding component, and the other end is provided with an outlet pipe 34 passing through from one side of the cooling water tank 32. The guiding component is installed on the machine cover 31.

[0030] It should be noted that the discharge port of the puffing body 1 is located inside the machine cover 31.

[0031] Regarding the description of the guiding component in the steam treatment mechanism 3, as Figures 2-4 shown, the guiding component includes a suction fan 35. The suction fan 35 is fixed to the machine cover 31 by bolts. An inlet pipe 36 penetrating into the machine cover 31 is provided at the inlet end of the suction fan 35, and a conduction pipe 37 connected to the heat exchange tube 33 is provided at the outlet end of the suction fan 35. In this way, when the suction fan 35 is started, first, the steam can be centrally guided to the conduction pipe 37, and then it enters the heat exchange tube 33 for heat exchange.

[0032] Therefore, when designed in this way, when the steam is guided by the guiding component, that is, when the suction fan 35 is started, first, the steam can be centrally guided to the conduction pipe 37, so that the steam at the discharge port of the puffing body 1 passes through the heat exchange tube 33, and then this steam can be converted into liquid through heat-exchanging and cooling means.

[0033] And it should also be noted that, as Figure 3 and 4 shown, the heat exchange tube 33 is spiral, and its spiral diameter expands sequentially from top to bottom, and it is immersed in the liquid. When the liquid is water, that is, the heat exchange tube 33 is immersed in water, and the material of the heat exchange tube 33 is preferably copper in this embodiment. Of course, it can be understood that the heat exchange tube 33 can also be other heat-conducting materials, such as one of steel, aluminum, nickel, and titanium, as long as the heat exchange requirement is met and the steam can be converted into liquid during heat exchange. The number of turns and height of the heat exchange tube 33 are determined according to the cooling water tank 32 and are not specifically defined here, but the overall height of the heat exchange tube 33 shall not exceed the cooling water tank 32. And each turn of the heat exchange tube 33 has an equal-distance height difference. With such a design, when the steam is converted into liquid in the heat exchange tube 33, the liquid can be discharged into the outlet pipe 34 more smoothly.

[0034] To complete the cutting of the puffed feed, in one embodiment, it further includes a cutting component 5. The cutting component 5 includes a motor, a reducer, a driving shaft, and a cutter. The input end of the reducer is connected to the output shaft of the motor, the driving shaft is installed at the output end of the reducer, and the cutter is fixed on the outside of the driving shaft and is located at the discharge port of the puffing body 1.

[0035] To enable the cut feed to flow out better, as Figure 2 shown, the hood 31 has a discharge port, and a material guiding seat 38 is arranged inside the hood 31. The drainage seat has an inclined surface for guiding the discharge of the puffed aquatic feed extruded by the puffing body 1, so that the puffed aquatic feed extruded by the puffing body 1 can be discharged from the discharge port.

[0036] It should also be noted that, as a preferred solution of this application, as Figures 1-4 shown, the cooling water tank 32 has an open upper end. In this way, the space inside the cooling water tank 32 is connected to the outside world to meet the basic heat dissipation requirement of the liquid in the cooling water tank 32 and ensure that the liquid in the cooling water tank 32 will not be in a high-temperature situation during short-time heat exchange. The liquid in the above cooling water tank 32 is, for example, water.

[0037] Considering that the aquatic feed puffing device in the factory sometimes needs to work continuously for a long time, to ensure that the liquid in the cooling water tank 32 can continuously complete the heat exchange of the steam, for this reason, in one embodiment, as Figure 3 and 4 shown, the aquatic feed puffing device further includes a refrigeration component 4. The refrigeration component 4 is arranged on one side of the cooling water tank 32 and is used to cool the liquid in the cooling water tank 32.

[0038] For further description of the refrigeration component 4, please continue to refer to Figure 3 and 4, the refrigeration assembly 4 includes a thermoelectric cooler 41. The thermoelectric cooler 41 is detachably connected to one side of the cooling water tank 32. A heat conduction plate 42 located in the cooling water tank 32 is provided at the cold end of the thermoelectric cooler 41 for cooling the liquid in the cooling water tank 32, and a fan 43 is provided at the hot end of the thermoelectric cooler 41.

[0039] Regarding the detachable connection between the thermoelectric cooler 41 and the cooling water tank 32, an installation hole is opened on one side of the cooling water tank 32, and the thermoelectric cooler 41 is installed at this installation hole. A corner plate is fixed outside the thermoelectric cooler 41, and a fixing bolt is threadedly connected between the corner plate and the cooling water tank 32, so that the thermoelectric cooler 41 and the cooling water tank 32 form a detachable connection relationship.

[0040] In addition, it should be noted that when direct current passes through an electric couple formed by two different semiconductor materials connected in series, heat will be absorbed and released at the two ends of the electric couple respectively, so as to achieve the purpose of refrigeration. This refrigeration technology is called the refrigeration technology that generates negative thermal resistance. Because it utilizes the special properties of semiconductor materials, when energized, one end will become cold and the other end will become hot, forming a temperature difference, and then realizing the transfer of heat.

[0041] Therefore, since the heat conduction plate 42 is arranged in the cooling water tank 32 and can be in direct contact with the liquid, when the thermoelectric cooler 41 works, through the conduction of the heat conduction plate 42, the liquid in the cooling water tank 32 can be kept in a low temperature state, so that the heat exchange tube 33 can continuously exchange heat, thereby ensuring that the aquatic feed puffing device can cope with the scenario problems of continuous long-term work and handling steam.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
