Description

Technical Field

[0001] The invention relates to the technical field of feed processing, in particular to drying equipment for feed processing. Background Art

[0002] In modern agriculture and animal husbandry, the quality of feed directly affects the health and growth efficiency of animals, so higher requirements are placed on feed processing and treatment. Feed processing usually includes multiple links such as raw material selection, crushing, mixing, pressing and drying. Among them, the drying process plays an important role in removing moisture from feed, extending the shelf life of feed, improving nutritional value, and improving the physical properties of feed.

[0003] At present, feed drying equipment mainly includes hot air dryer, spray dryer, fluidized bed dryer, etc. Although these equipment can achieve a certain drying effect in practical applications, there are still some shortcomings, such as: 1. High energy consumption: Traditional drying equipment often consumes a lot of heat energy, which not only increases production costs, but also has a significant impact on the environment. Especially in the context of rising energy prices, it is particularly important to find a more efficient drying method; 2. Uneven drying: When using hot air dryers or fluidized bed dryers, the drying of materials is often not uniform, resulting in some feed being over-dried, while other feeds fail to achieve the ideal drying effect. This uneven drying not only affects the overall quality of the feed, but may also have a negative impact on the health of the animals; 3. Easy to deteriorate: Some feed raw materials contain high levels of fat and protein. Traditional drying equipment can easily cause the nutritional components of the feed to deteriorate at high temperatures, thereby reducing its nutritional value. This has a significant impact on animals that rely on feed as their main food source; 4. The equipment occupies a large area: Many existing drying equipment is large in size and occupies a large area, which is very inconvenient to use for small feed processing plants with limited space, limiting their production capacity; 5. Difficult maintenance: Some drying equipment has a complex structure and high requirements for operation and maintenance, which increases the difficulty of using the equipment and the maintenance cost. For some small and medium-sized enterprises, they cannot afford the high maintenance costs and technical training costs.

[0004] In view of the above problems, the feed industry is in urgent need of a new type of drying equipment to improve drying efficiency, reduce energy consumption, improve drying uniformity, and have better operability and maintainability.

[0005] In summary, the development of a drying equipment for feed processing that is efficient, energy-saving, uniformly dried, and easy to operate will play an important role in improving the overall efficiency of feed processing, reducing production costs, improving feed quality, and promoting the sustainable development of animal husbandry.

In the process of hot air flow circulation, heat energy is lost, so the temperature of the hot air flow entering the drying bin for drying the mixed feed meets the requirements for drying the mixed feed, and because the source of this hot air flow is the drying of meat feed, a small amount of oil components are attached to the air flow, and a small amount of oil components entering the mixed feed can improve the production quality of the mixed feed, and due to the presence of oil, if the hot air flow is not guided to the drying bin to which the meat feed belongs, a thick layer of oil will be attached to the drying bin, resulting in a strong temperature storage capacity of the drying bin, making it impossible to control the drying temperature of the drying bin. Through the above process, the drying system can be helped to dry the feed with stable drying data to ensure uniform drying of the feed. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-13 The present invention provides a technical solution: a drying device for feed processing, comprising a base 1, a limiting frame 2 is fixedly installed on the top of the base 1, the limiting frame 2 is made of metal, and a first drying bin 3 and a second drying bin 4 are arranged in the limiting frame 2;

[0041] A drying equipment for feed processing matches the drying system, and uses an intelligent system for the drying process;

[0042] The first drying chamber 3 includes two support members 5 fixedly mounted on the base 1, and a side sealing plate 6 is welded on the facing surfaces of the two support members 5. An upper shell 7 and a lower shell 8 are detachably mounted between the two side sealing plates 6. The upper shell 7, the lower shell 8, and the two side sealing plates 6 form a closed drying space.

[0043] A rotating shaft 9 is arranged between the two side sealing plates 6, a bearing at one end of the rotating shaft 9 is installed on the inner side wall of one of the side sealing plates 6, a clamping groove 10 is welded on the outer side wall of the other side sealing plate 6, a motor 11 is fixedly installed on the groove surface of the clamping groove 10, an output end of the motor 11 passes through the adjacent side sealing plates 6 and is fixedly connected to the other end of the rotating shaft 9, a stirring net 12 is welded on the side wall of the rotating shaft 9, the motor 11 is controlled by the drying system, the motor 11 is controlled to run through the drying system, the motor 11 runs to drive the rotating shaft 9 to rotate, and the rotating shaft 9 rotates to drive the stirring net 12 to rotate;

[0044] The rotating shaft 9 is a hollow rod with an inner wall, and an electric heating device is arranged inside the rotating shaft 9. The electric heating device heats the rotating shaft 9 and heats the stirring net 12 connected to the rotating shaft 9 until the feed is dried.

[0045] A filter housing 31 is disposed on the surface of the end portion of the rotating shaft 9 away from the motor 11. A plurality of filter holes 32 are evenly disposed on the surface of the filter housing 31. Part of the filter housing 31 extends out through a nearby side sealing plate 6. An external conveying hole 34 is disposed at the filter housing 31 outside the side sealing plate 6. The filter holes 32 are used to prevent feed from overflowing while ensuring liquid discharge.

[0046] An independent valve 33 is provided at each filter hole 32, and each independent valve 33 is controlled by the drying system;

[0047] The liquid in the drying chamber enters the filter housing 31 through the filter hole 32 and then is discharged through the delivery hole 34;

[0048] The first drying bin 3 and the second drying bin 4 have the same structure. The purpose of setting up two drying bins is to dry meat feed and mixed feed at the same time. The mixed feed is a feed formed by mixing vegetables, grains, and a small amount of protein. Different animals have different feeding needs. Four groups of production mechanisms 13 are fixedly installed on the limiting frame 2. The four groups of production mechanisms 13 have the same structure. The production mechanism 13 includes an auxiliary bin 14. Four upper feed holes 15 are arranged on the auxiliary bin 14. Two lower feed holes 16 are arranged on the top of the upper shell 7 of the two drying bins. The upper feed holes 15 are sealed and aligned with the lower feed holes 16, and the bottom part of the auxiliary bin 14 is fixed to the top part of the upper shell 7. At the same time, the auxiliary bin 14 is also fixed on the limiting frame 2, so that the entire first drying bin 3 and the second drying bin 4 from top to bottom are structurally stable during the drying process;

[0049] A set of unloading components 17 is arranged on each upper feed hole 15, and the unloading components 17 include a control tube 18 sealedly connected to the upper feed hole 15, and the top of the control tube 18 is sealedly connected to the storage tube 19. An intelligent valve is arranged in the control tube 18, and the intelligent valve is controlled by the drying system. The diameter of the control tube 18 is smaller than that of the storage tube 19. This arrangement can reduce the feeding speed when the feed enters the drying bin. Each time the feed is transported into the drying bin, after the drying bin is filled with feed, it is necessary to leave enough feed in the control tube 18 and the storage tube 19. Since the drying bin dries the feed, the water inside the feed evaporates and the volume of the feed shrinks. Leaving enough feed in the control tube 18 and the storage tube 19 can ensure that the amount of feed dried in the drying bin is sufficient each time, thereby improving the feed drying efficiency. Setting the diameter of the control tube 18 slightly smaller can also improve the temperature storage performance in the drying bin.

[0050] The top of the storage tube 19 is sealed and connected to the constant temperature bin 21, the top of the constant temperature bin 21 is sealed and connected to the conical tube 22, a fan 30 is arranged on the top of the conical tube 22, the blowing nozzle of the fan 30 is inside the conical tube 22, and the blowing direction is downward, the top of the conical tube 22 is sealed and connected to the feeding box 23, and a slidable sealing plate 24 is arranged on the top of the feeding box 23. When it is necessary to transport feed into the first drying bin 3 and the second drying bin 4, the sealing plate 24 is opened manually, and then the feed transporting pipeline is inserted into the feeding box 23, and the feed is started to be transported from the feeding box 23. The feed enters the first drying bin 3 and the second drying bin 4 via the feeding box 23, the conical tube 22, the constant temperature bin 21, the storage tube 19, and the control tube 18. After the feed is transported, the feed transport pipe is pulled out, and finally the sealing plate 24 is closed. The feed transport pipe and related equipment are all existing technical structures, and their function is feed pumping, which will not be described in detail here. Each drying bin is equipped with two production mechanisms 13, one production mechanism 13 of each drying bin is used for feed transport, and the other production mechanism 13 is used for gas exchange. All production mechanisms 13 are set to a unified structure. The purpose is that when one of the production mechanisms 13 is damaged, another production mechanism 13 on the same drying bin can be replaced in time to continue feed transport or gas exchange. Compared with different structures to achieve a single purpose, this structural setting can improve the fault tolerance of the equipment;

[0051] A number of heating components 25 are fixedly installed on the inner wall of the constant temperature bin 21 from top to bottom. Each heating component 25 is made of a heating wire that surrounds the constant temperature bin 21 on a horizontal plane. Its function is to heat by electricity. An upper valve 26 is set at the top of the constant temperature bin 21, and a lower valve 27 is set at the bottom of the constant temperature bin 21. The upper valve 26 and the lower valve 27 are both controlled by the drying system. Before the production mechanism 13 is used for feed transportation, the drying system drives the heating component 25 to heat, and the constant temperature bin 21 is preheated by the heating component 25. During the preheating process, the upper valve 26 and the lower valve 27 are closed by the drying system, and then the heating component 25 is driven to heat the space of the constant temperature bin 21. The drying system sets the preheating time of the constant temperature bin 21. When the preheating time is reached, the upper valve 26 is opened to transport the feed into the constant temperature bin 21. The amount is quantitative, and its purpose is to fill the constant temperature bin 21. When the constant temperature bin 21 is full of feed, the feed delivery is stopped, and the upper valve 26 is closed. The drying system presets the drying time of the feed in the constant temperature bin 21. When the drying time is reached, the lower valve 27 is opened to deliver the preheated feed to the drying bin. The purpose is to heat the feed. First, remove the stickiness of the feed and disperse the feed to facilitate the feed to enter the drying bin for drying. Second, when the heated feed is delivered to the drying bin, the temperature difference between the heated feed and the temperature in the drying bin is small, so that the feed will not be subjected to a large temperature difference in a short time. A large temperature difference in a short time is easy to cause the loss of nutrients in the feed. Therefore, during the process of feed delivery, the feed is heated in a step-by-step manner to gradually increase the temperature of the feed, and then finally realize the drying process of the feed while ensuring the nutritional value of the feed.

[0052] Several mesh plates 28 are fixedly installed in the storage tube 19 from top to bottom. The mesh holes on the mesh plates 28 are relatively large, which is convenient for the feed to pass through. Since the mesh plates 28 are made of metal, heating wires are arranged inside the mesh plates. The mesh plates are heated by the heating wires to prevent the temperature of the feed entering the drying bin from dropping through the mesh plates 28. At the same time, the mesh plates and the heating components 25 form multiple heat-sealed channels to prevent the temperature in the drying bin from being lost upwards.

[0053] After the feed is transported, the upper valve 26 and the lower valve 27 are both opened to facilitate the feed to freely enter the drying bin;

[0054] A discharge valve 20 is provided at the bottom of the lower shell 8 of the two drying bins. The discharge valve 20 is controlled by the drying system. When the feed in the first drying bin 3 and the second drying bin 4 is dried, the storage box is manually pushed under the discharge valve 20, and the discharge valve 20 is opened by the drying system. At this time, the stirring net 12 continues to rotate, and the dried feed in the first drying bin 3 and the second drying bin 4 is discharged into the storage box through the discharge valve 20;

[0055] An extension tube 29 is arranged on the side wall of the conical tube 22 on each group of production mechanisms 13. Before drying the feed, after selecting each production mechanism 13 for conveying feed on the drying, the production mechanisms 13 for not conveying feed on the two drying bins are connected by a hose. The connection method is to seal one end of the hose to the extension tube 29 on one group of production mechanisms 13, and the other end to the other extension tube 29. When the meat feed and the mixed feed are dried, the drying temperature is inconsistent. The drying temperature of the meat feed is high, and the drying temperature of the mixed feed is low. When drying at the same time, the temperature in the drying bin for the meat feed is high, and the internal gas enters the top of the production mechanism 13 of the drying bin where the mixed feed is dried through the hose, and then the accumulated feed is blown away by the fan 30 arranged on the top of the conical tube 22. The hot air flow at the top of the production mechanism 13 is returned to the drying bin for drying the mixed feed to realize the reuse of the hot air flow. In the process of hot air flow circulation, heat energy is lost, so the temperature of the hot air flow entering the drying bin for drying the mixed feed meets the requirements for drying the mixed feed. Since the source of this hot air flow is the drying of meat feed, a small amount of oil components are attached to the air flow. A small amount of oil components entering the mixed feed can improve the production quality of the mixed feed. Due to the presence of oil, if the hot air flow is not guided to the drying bin to which the meat feed belongs, a thick layer of oil will be attached to the drying bin, resulting in a strong temperature storage capacity of the drying bin, making it impossible to control the drying temperature of the drying bin. Through the above process, the drying system can be helped to dry the feed with stable drying data to ensure uniform drying of the feed.

[0056] When the feed is dried, water may seep into the drying bin. At this time, the water seeping out of the drying bin needs to be discharged. If the feed is heated only by the rotating shaft 9, the drying time will be too long, the energy consumption will be too high, and the nutrient loss of the dried feed will be serious. Therefore, before drying the feed, a matching connecting pipe is installed on the bearing of the conveying hole 34. The connecting pipe is sealed and connected to a storage shell with a pump. The pump is remotely controlled by the drying system. The pumping frequency is preset in the drying system. When pumping, the drying system opens the independent valve 33 and drives the pump to suck a small amount of liquid in the drying bin into the storage shell. The liquid accumulated in the storage shell can be processed and used to make mixed feed again.

[0057] When setting the pumping frequency of the drying system, the pumping frequencies of meat feed and mixed feed are different, and different settings are required according to the type of feed.

[0058] Three groups of auxiliary material adding components 40 are arranged on the outside of each storage tube 19. The auxiliary material adding components 40 include a bending plate 35 fixedly installed on the outer wall of the storage tube 19, a lifting rail 36 is arranged on the side wall of the bending plate 35, a cross bracket 37 is slidably connected to the lifting rail 36, a pressure rod 38 is arranged on the cross bracket 37, an auxiliary material storage box 39 is fixedly installed in the end area of ​​the bending plate 35, the pressure rod 38 is snap-fitted and installed in the auxiliary material storage box 39, a material pipe is arranged at the bottom of the auxiliary material storage box 39 to be sealed and connected to the storage tube 19, the material pipe is hidden in the bending plate 35, and the cross bracket 37 has a built-in energy supply system. The energy supply system is controlled by the drying system. The cross bracket 37 is driven to move up and down along the lifting rail 36, and the cross bracket 37 drives the pressure rod 38 to move up and down. When the auxiliary materials in the auxiliary material storage box 39 need to be used, the pressure rod 38 is lowered to squeeze the auxiliary materials in the auxiliary material storage box 39 out, so that the auxiliary materials enter the auxiliary material storage box 39 through the material pipe. The three sets of auxiliary material adding components 40 can add three different auxiliary materials, which are arranged on the outside of the storage tube 19. First, the space inside the storage tube 19 is large, so that the auxiliary materials are prevented from contacting the inner tube wall of the storage tube 19. Second, the storage tube 19 is close to the drying chamber, and the temperature inside it is continuously high, so the auxiliary materials can be heated at a low temperature to prevent the auxiliary materials from solidifying.

[0059] Compared with adding auxiliary materials manually, the method of adding auxiliary materials in this embodiment can avoid the danger of high temperature to labor and is more efficient. Compared with adding auxiliary materials before the feed enters the drying bin, the auxiliary materials can easily volatilize their nutrients in the air. The method of adding auxiliary materials in this embodiment can reduce the amount of auxiliary materials used. It only needs to be added at several time points when the feed is dried to ensure that the nutrition of the feed is sufficient. The role of the auxiliary materials is to supplement the nutrients lost by the feed in the drying bin. By regularly delivering different types of auxiliary materials into the drying bin, insufficient nutrients are lost to ensure that the nutrients do not deteriorate.
