[0002] Feed cookers are one of the key pieces of equipment in the feed processing process. They are mainly used to heat and cook feed raw materials with high-temperature steam, which can kill harmful microorganisms in the feed and ensure the hygiene and safety of the feed. In the existing technology, the steam nozzles are oriented upwards. When the steam is sprayed upwards to heat the feed, the upward resistance is large and the heat loss is serious, resulting in slow cooking and heating of the feed. At the same time, some areas of the feed are overheated and the heating is uneven.

[0003] Therefore, we provide a feed cooker to solve the above problems. Utility Model Content

The vortex section includes a vortex ring, a plurality of air inlets arranged tangentially along the vortex ring, an air channel formed within the vortex ring, and a nozzle for injecting high-pressure gas into the housing. The vortex ring is sealed to the housing. The air inlets are used to deliver high-pressure steam into the housing. The air inlets, the air channel, and the nozzle are connected.

[0008] In some embodiments, the nozzle is arranged circumferentially on the inner side of the vortex ring, the direction in which the nozzle ejects gas on the horizontal plane makes an angle of -0 degrees with the radial direction of the vortex ring, and the direction in which the nozzle ejects gas makes an angle of - degrees with the axial direction of the vortex ring.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the accompanying drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures.

The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] In related technical fields, when feed cookers use steam to cook feed, steam vents are usually set below the feed. Taking advantage of the low density of steam, the steam penetrates the feed layer from bottom to top, thereby achieving heat transfer and cooking of the feed. However, during heating, because the steam passively passes through the feed layer, the heating effect of the feed is not high. Some feed cooking gases are pressurized by stirring the feed and then directly injected into the feed layer from bottom to top. Although this increases the heating speed compared to the former case, after the feed is turned over, the penetrating power of the directly injected air is not strong, which cannot improve the heating efficiency. At the same time, the directly injected steam can cause overheating in a certain area of ​​the feed layer, making it impossible to heat the feed layer evenly.

[0021] During the research process, the inventors discovered that if the steam nozzle is tilted, the tangential deflection angle of the steam nozzle will change the rotational torque and penetrating force of the steam. When the steam nozzle is tilted downwards, the pressurized high-pressure steam penetrates from top to bottom. Compared to "pressing" the feed layer, it has less resistance and deeper penetration. Meanwhile, the condensate flows downwards without re-wetting the feed layer, avoiding localized over-wetting or clumping. This allows heat and moisture to be evenly pressed into the feed layer, achieving uniform heating of the feed and shortening the heating time.

[0022] Based on the above findings, this application proposes a feed cooker that heats the feed layer through an inclined steam nozzle. The steam is ejected along the direction of the steam nozzle and forms a vortex in the chamber. Under the stirring and turning action of the stirring plate, the penetration of steam into the feed layer and the exchange efficiency of temperature and humidity are greatly improved, while making the feed layer more evenly heated.

[0023] The following is for reference. Figures 1 to 8 The feed cooker of some embodiments of this application will be described in detail. The feed cooker of some embodiments of this application includes a box body 1, which is hollow barrel-shaped, and a discharge port 2 is provided on the side of the box body 1. A support 3 is provided at the bottom of the box body 1, and a drive unit 4 is also provided at the bottom of the box body 1. A pressure gauge 5 for monitoring the gas pressure inside the box body 1 is provided at the top of the box body 1. A pressure relief valve 6 is provided on one side of the pressure gauge 5. A feed inlet 7 is rotatably sealed at the top of the box body 1.

[0024] In some embodiments, the stirring unit 8 is disposed inside the housing 1 and is used to stir the food inside the housing 1.

[0025] In some embodiments, the vortex section 9 is used to form high-pressure vortices within the housing 1.

[0026] In this embodiment, the hollow barrel-shaped box 1 is used to hold feed and perform steaming operations. The drive unit 4 meshes with the transmission gear 83 at one end of the stirring shaft 81 of the stirring unit 8. The stirring shaft 81 and the box 1 are rotatably connected, so that the rotation of the drive unit 4 can drive the transmission gear 83 to rotate, which in turn drives the stirring shaft 81 to rotate. This allows the stirring unit 8 to continuously tumble the food in the box 1 by means of the stirring base 82, completing the stirring operation. The vortex unit 9 is provided with air channels 93 and 94 for accommodating steam, and the nozzles 94 and 94 are... The vortex rings 91 and 94 are arranged diagonally downwards. When multiple nozzles 94 and 94 spray high-pressure steam, the steam rotates around the barrel wall, forming a "tornado"-like vortex that penetrates the feed layer. Compared with traditional steam directly hitting the feed layer, this method can transfer more of the temperature and humidity contained in the steam to the feed. At the same time, because the stirring part 8 is constantly turning the feed layer, it increases the mixing area between the feed and the steam, "twisting" the steam into the feed layer, avoiding local overheating of the feed, and transferring the heat and moisture contained in the steam to the feed, thereby increasing the heating speed and shortening the cooking time.

[0027] refer to Figure 1 , Figure 7 and Figure 8 In some embodiments, the stirring part 8 is rotatably disposed inside the housing 1. The stirring part 8 includes a stirring shaft 81, a stirring base 82, and a transmission gear 83. Both ends of the stirring shaft 81 pass through the housing 1, and the axis of the stirring shaft 81 is on the same straight line as the axis of the housing 1. The stirring shaft 81 and the housing 1 are rotatably connected. The stirring base 82 is constructed on the outer side of the stirring shaft 81. The stirring base 82 is used to stir the food in the housing 1. The bottom end of the stirring shaft 81 is connected to the transmission gear 83. The transmission gear 83 meshes with the drive part 4. The drive part 4 is used to drive the stirring part 8 to rotate.

[0028] In this embodiment, the stirring shaft 81 of the stirring unit 8 can rotate around the same axis as the housing 1, and is engaged with the drive unit 4 through the transmission gear 83. Preferably, in this embodiment, the drive unit 4 is a motor.

[0029] In Example 1.

[0030] refer to Figure 3 , Figure 5 and Figure 7In some embodiments, a vortex section 9 is provided in the middle section of the box body 1. The vortex section 9 includes a vortex ring 91, a plurality of air inlets 92 arranged tangentially along the vortex ring 91, an air channel 93 formed in the vortex ring 91, and a nozzle 94 for injecting high-pressure gas into the box body 1. The vortex ring 91 and the box body 1 are sealed together. The air inlets 92 are used to deliver high-pressure steam into the box body 1. The air inlets 92, the air channel 93, and the nozzle 94 are connected. The vortex ring 91 is located in the middle section of the box body 1 and its horizontal height is higher than the height of the feed layer in the box body 1. By introducing high-pressure steam into the air inlets 92, the high-pressure steam is ejected from the nozzle 94 along the air channel 93 in the vortex ring 91.

[0031] refer to Figure 6 In some embodiments, the nozzle 94 is arranged circumferentially on the inner side of the vortex ring 91, and the angle between the direction of the gas ejected by the nozzle 94 on the horizontal plane and the radial direction of the vortex ring 91 is 15-30 degrees, and the angle between the direction of the gas ejected by the nozzle 94 and the axial direction of the vortex ring 91 is 15-25 degrees. In this embodiment, preferably, the angle between the direction of the gas ejected by the nozzle 94 on the horizontal plane and the radial direction of the vortex ring 91 is 20 degrees, and the angle between the direction of the gas ejected by the nozzle 94 and the axial direction of the vortex ring 91 is 20 degrees.

[0032] In this embodiment, the combined setting of the angle of the nozzle 94 on the horizontal plane and the angle along the axial direction makes the gas ejected from the nozzle 94 form a certain angle along the barrel wall of the box 1, thereby causing the air inside the box 1 to form a vortex inside the box 1.

[0033] In some embodiments, at least two nozzles 94 are provided; preferably, in this embodiment, four nozzles 94 are provided.

[0034] In Example 2.

[0035] In some embodiments, the vortex section 9 is fixedly connected to the stirring shaft 81. The vortex section 9 includes a vortex ring 91, an air inlet 92, an air channel 93, and a nozzle 94. The vortex ring 91 is constructed in the middle section of the stirring shaft 81. The air inlet 92 is located at one end of the stirring shaft 81 near the feed inlet 7. An air channel 93 is formed between the hollow space of the stirring shaft 81, the vortex ring 91, and the air inlet 92. The nozzle 94 is connected to the air channel 93. The stirring shaft 81 is a hollow tube. An air inlet 92 is provided at one end of the stirring shaft 81 near the feed inlet 7, and a sealing valve is provided at the other end. Due to the condensate flowing out of the stirring shaft 81, high-pressure steam enters the stirring shaft 81 from the air inlet 92 and is guided along the vortex ring 91 and the air channel 91 before being ejected from the nozzle 94.

[0036] In some embodiments, the nozzle 94 is disposed on the outer side of the vortex ring 91 in the circumferential direction. The angle between the direction of the gas ejected by the nozzle 94 on the horizontal plane and the radial direction of the vortex ring 91 is 15-30 degrees, and the angle between the direction of the gas ejected by the nozzle 94 and the axial direction of the vortex ring 91 is 15-25 degrees. Preferably, the angle between the direction of the gas ejected by the nozzle 94 on the horizontal plane and the radial direction of the vortex ring 91 is 20 degrees, and the angle between the direction of the gas ejected by the nozzle 94 and the axial direction of the vortex ring 91 is 20 degrees.

[0037] In this embodiment, the nozzle 94 is tilted outward in the radial direction. The high-pressure steam ejected from the nozzle 94 impacts the barrel wall of the box 1 and rotates along the barrel wall, thereby forming a vortex inside the box 1.

[0038] In this embodiment, a stacking tray 11 with small holes is provided on the upper inner wall of the box 1. The stacking tray 11 is located below the mixing base 82. The stacking tray 11 is used to stack the feed to be processed. The stacking tray 11 has multiple small holes to drain excess water from the feed during the cooking process. The excess water accumulates at the bottom of the feed under the action of gravity and falls from the small holes, thus preventing the feed from clumping due to excessive moisture during the cooking process.

[0039] In this application, a suitable amount of feed is added into the box 1, and the height of the feed must not exceed the height of the vortex 91, 91. A steam engine is connected to the air inlet 92, 92, and high-pressure steam is introduced. At the same time, the drive unit 4 is started, and the drive unit 4 drives the stirring shaft 81 to start rotating. The stirring shaft 81 starts to turn the feed in the box 1. At this time, the high-pressure steam sprayed from the nozzle 94, 94 starts to rotate around the barrel wall of the box 1 under the constraint of the inclined nozzle 94, 94, thus forming a continuously rotating vortex in the box 1. The rotating vortex steam has a higher penetrating power than the steam that is normally directly sprayed into the feed, and can penetrate the feed layer, so as to transfer more and more temperature and humidity to the feed layer. At the same time, since the stirring base 82 is constantly turning the feed layer, it can prevent the local overheating of the feed layer, transfer more heat to the feed layer, effectively shorten the cooking time, and make the feed more evenly heated.

[0040] The feed cooker of this embodiment eliminates the need for manual cleaning of the grid. A high-speed water jet from the internal cleaning mechanism washes away contaminants collected on the grid surface, reducing manual labor and improving work efficiency. The use of a rotating cage, fixed to and rotating synchronously with the shaft, minimizes the number of mechanical parts, resulting in a simple structure and easy maintenance. A collection box located at the bottom of the unit draws contaminants into the unit and collection box for treatment, further reducing the device's footprint.

[0041] Based on the above embodiments of this utility model, in the absence of explicit denial or conflict, the technical features of one embodiment can be advantageously combined with one or more other embodiments. Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
