Description

Technical Field

[0001] The invention belongs to the field of piglet feed production and application, and in particular relates to high-temperature baking equipment for piglet feed. Background Art

[0002] Piglets refer to piglets from birth to weaning. During this stage, piglets grow and develop very rapidly, but they are also very fragile and susceptible to various diseases. Therefore, raising piglets requires special attention to feeding management and disease prevention.

[0003] At present, the main starch-containing grains in the diet of piglets generally account for about 60% of the diet. Taking corn as an example, more than 70% of corn seeds are starch, of which about 27% are amylose and 73% are amylopectin. Corn starch is densely arranged in the endosperm in the form of starch granules. The starch chains are connected to each other by hydrogen bonds and arranged in an orderly manner to form a crystalline area. Therefore, improving the utilization rate of corn starch is the key to improving the production performance and breeding benefits of livestock and poultry. The main processing methods of corn include crushing, granulation, steam flaking, puffing, baking, etc.

[0004] Baked feed is produced by infrared baking and flake feed process, which mainly consists of three parts, including feed soaking, infrared baking and flake pressing. This process can change the starch crystal structure to the greatest extent, improve the gelatinization degree of baked feed, and prevent the retrogradation of starch in grains.

[0005] At present, infrared baking of grains is mainly carried out by ovens with stirring equipment or tunnel ovens. Ovens with stirring equipment can bake grains more evenly, but they cannot achieve continuous processing and are greatly affected by the size of the oven. Although tunnel ovens can process grains continuously, they can only bake one side separately. Therefore, in order to ensure uniform baking, the paving thickness is generally thinner, which increases production costs. Therefore, how to achieve continuous production and achieve a thicker paving thickness is a problem that needs to be solved at present. Summary of the invention

[0006] Aiming at the technical problems existing in the existing infrared baking of grains, the present invention proposes a high-temperature baking device for piglet feed which has reasonable design, simple structure, convenient transformation and can realize continuous and high-thickness baking.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: the present invention provides a high-temperature baking equipment for piglet feed, comprising a conveyor frame and an infrared oven arranged on the conveyor frame, the conveyor frame comprising a frame and a conveyor belt arranged on the frame, the conveyor belt comprising a horizontal section and a falling section arranged between the horizontal sections, the conveyor belt lowers the height of the horizontal section through the falling section, at least two falling sections are arranged on the conveyor belt, the horizontal section is provided with a receiving box for receiving the falling sections, the bottom plate of the receiving box is inclined downward, a receiving plate is arranged in the receiving box, the receiving plate is inclined upward along the conveying direction of the conveyor belt, a rotating shaft is arranged in the receiving box, the rotating shaft is rotatably arranged in the receiving box, a paddle plate is arranged on the rotating shaft, the paddle plates are evenly distributed on the side walls of the rotating shaft, the end of the paddle plate away from the rotating shaft is arranged in a gap with the bottom of the receiving box, and the paddle plate paddles the feed at the bottom of the receiving box upward.

[0008] Preferably, an arc-shaped groove is provided at the bottom of the material receiving box, and the shift plate is arranged in cooperation with the arc-shaped groove.

[0009] Preferably, the falling section is arranged to be inclined backward along the transport direction of the conveyor belt, and the end plate of the material receiving box close to the falling section is arranged to be inclined in contact with the falling section.

[0010] Preferably, the conveyor belt is provided with three falling sections.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. The present invention provides a high-temperature baking equipment for piglet feed. By improving the structure of the existing conveyor belt, the horizontal conveying is changed to horizontal falling conveying. The falling process is used in conjunction with a paddle to stir the grains, so that the baking surface of the next section of grains is changed, thereby achieving the purpose of uniform baking, thereby increasing the thickness of the feed on the conveyor belt and reducing the production cost.

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1, as Figure 1 to Figure 3 As shown, the present embodiment aims to realize large-scale, continuous and uniform high-temperature baking of feed. Considering that continuous baking can only be achieved by adopting a tunnel-type structure, the present embodiment provides a high-temperature baking device for piglet feed, including a conveyor frame 1 and an infrared oven 2 arranged on the conveyor frame 1. The conveyor frame 1 includes a frame 1 and a conveyor belt 12 arranged on the frame 1. The above structure is a common structure of an existing common tunnel-type infrared oven 2. Therefore, in the present embodiment, it is not described in detail.

[0021] Taking into account the disadvantage of the tunnel oven that the baking surface is single-sided (if an infrared lamp is installed below, there is a risk of leakage), how to make the feed move on the conveyor belt 12 so that uniform baking can be achieved. To this end, in the present embodiment, the conveyor belt 12 includes a horizontal section 121 and a falling section 122 arranged between the horizontal sections 121. The conveyor belt 12 lowers the height of the horizontal section 121 through the falling section 122. The falling section 122 is mainly guided by gears or rollers to make the conveyor belt 12 move obliquely downward. In the present embodiment, the falling section 122 is arranged obliquely backward along the transport direction of the conveyor belt 12. In this way, the feed in the horizontal section 121 falls directly downward instead of moving directly along the falling section 122. The falling of the feed will cause the baked feed to change.

[0022] In order to avoid the feed splashing due to the falling height being too high, and at the same time to better switch the roasted feed (move the feed below to the top), a receiving box 3 for receiving the falling material of the falling section 122 is provided in the horizontal section 121, and a discharge port 31 is provided at the front end of the receiving box (with the transportation direction of the conveyor belt as the front). Since the receiving box 3 is unpowered, in order to avoid the feed from accumulating in the receiving box 3, in this embodiment, the bottom plate of the receiving box 3 is tilted downward, so that the feed can slide downward by utilizing the power of the feed itself.

[0023] At the same time, in order to further ensure the change of the baked feed, a receiving plate 32 is provided in the receiving box 3. The receiving plate 32 is arranged upwardly along the transport direction of the conveyor belt 12. The receiving plate 32 has multiple purposes. One is to reduce the falling height of the feed so that it cooperates with the receiving box 3 to avoid feed splashing. Second, the loading of the receiving plate 32 will produce moving rolling during the falling process, thereby better adjusting the baked feed.

[0024] In order to further improve the adjustment of the roasted feed by the receiving box 3, a rotating shaft 33 is provided in the receiving box 3. The rotating shaft 33 is rotatably arranged in the receiving box 3. A dial plate 34 is arranged on the rotating shaft 33. The dial plates 34 are evenly distributed on the side wall of the rotating shaft 33. In this embodiment, a total of four dial plates 34 are arranged, and the angle between adjacent dial plates is 90°. The dial plate 34 is arranged at a gap between the end of the dial plate 34 away from the rotating shaft 33 and the bottom of the receiving box 3. The dial plate 34 is arranged to dial the feed at the bottom of the receiving box 3 upward. The main reason for dialing upward is that the dialing changes the height of the feed, which may cause the roasted feed to change. Dialing downward will only speed up the sliding speed of the feed on the bottom plate of the receiving box 3. If the rotating speed of the rotating shaft 33 is too fast, the centrifugal force generated by it can be used to swing the feed, thereby better adjusting the roasted feed. Of course, at this time, a part of the receiving plate 32 needs to be above the rotating shaft 33 to prevent the feed from flying around.

[0025] Considering that the adjustment of the baked feed may not be achieved by one adjustment, for this reason, at least two drop sections 122 are provided on the conveyor belt 12. In this embodiment, three drop sections 122 are provided on the conveyor belt 12. In this way, by moving the feed on the conveyor belt 12, the baked feed can be adjusted, and evenly baking can be ensured even when the thickness is relatively thick.

[0026] In order to further adjust the roasted feed, an arc-shaped groove 35 is provided at the bottom of the receiving box 3, and the paddle plate 34 is arranged in cooperation with the arc-shaped groove 35. Here, the paddle plate 34 and the arc-shaped groove 35 are arranged in cooperation, which means that the paddle plate 34 paddles the feed from the arc-shaped groove 35, so that the feed dropped from the receiving plate 32 will be accumulated in the arc-shaped groove 35, and after the paddle plate 34 paddles the feed, the feed in the arc-shaped groove 35 will move further, thereby adding another adjustment space, thereby ensuring the adjustment of the roasted feed.

[0027] Through the above arrangement, the feed required for baking is stirred and adjusted on the conveyor belt 12, thereby ensuring the baking of the lower layer of feed, increasing the baking amount, and achieving the purpose of large-scale, continuous and uniform high-temperature baking of feed.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
