Technical Field

[0001] This application relates to the technical field of animal aggregate processing equipment, and particularly relates to an energy-efficient and continuous drying system for aggregates. Background Art

[0002] Fresh livestock and poultry bones are a very important by-product in the meat processing industry. Fresh livestock and poultry bones contain a relatively high proportion of high-quality protein, and bone protein and other bioactive substances can be extracted through technologies such as enzymatic hydrolysis to develop functional foods with specific health functions, such as bone protein products like peptone, bone glue, and gelatin, and health products like chondroitin.

[0003] During the processing of fresh livestock and poultry bones, in the pretreatment stage, the sorted fresh bones need to be cleaned to remove impurities and residual meat, and the cleaned fresh bones need to be dried to ensure the freshness and safety of the fresh bones. However, traditional fresh bone drying technologies have many deficiencies, such as low drying efficiency, high energy consumption, uneven drying, etc., which affect product quality and cannot meet the needs of large-scale production. Summary of the Utility Model

[0004] The purpose of this utility model is to provide an energy-efficient and continuous drying system for aggregates, which can continuously dry fresh bones, improve drying efficiency and product quality, and meet the energy-efficient needs of large-scale production of fresh bones.

[0005] This application is achieved through the following technical solutions, specifically:

In the second drying chamber, the hot air supply device is connected through the air inlet to provide hot air flowing from bottom to top for the second conveyor device to dry the aggregates conveyed on the second conveyor device and remove the moisture inside. The design of this solution enables the aggregates to receive different degrees of heat and air flow treatment at different stages, continuously drying the aggregates, which is conducive to more precisely controlling the drying process and avoiding problems such as over-drying or insufficient drying, thereby improving the drying efficiency and quality.

[0014] The beneficial effects of this application are as follows:

[0015] The solution of this application segments the drying of the washed aggregate by setting up two drying chambers. In the first drying chamber, the first conveying device cooperates with the air blowing device above. During the conveying of the aggregate, the air blowing device arranged above the first conveying device blows gas through a blower and multiple air nozzles towards the aggregate to take away the moisture on the surface of the aggregate. In the second drying chamber, a hot air supply device is connected through an air inlet to provide hot air flowing upward from bottom to top for the second conveying device to dry the aggregate conveyed on the second conveying device and remove the moisture inside it. The design of this solution enables the aggregate to receive different degrees of heat and air flow treatment at different stages, continuously drying the aggregate, which is conducive to more precisely controlling the drying process, avoiding problems such as over-drying or insufficient drying, and thus improving the drying efficiency and quality.

Detailed Embodiment

[0021] The following will be combined with the attached Figures 1-2 The embodiments of the technical solution of this application will be described in detail. The following embodiments are only used to illustrate the technical solution of this application more clearly, so they are only examples and cannot be used to limit the protection scope of this application. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] In view of the problems existing in the prior art in the background art, an embodiment of the present application provides an efficient energy-saving continuous aggregate drying system, as Figures 1-2 shown in the structural schematic diagram. The efficient energy-saving continuous aggregate drying system includes: a feed bin 1, a first drying chamber 2 connected below the feed bin 1, a first conveyor device 3 disposed in the first drying chamber 2, a blowing device 4 disposed above the first conveyor device 3, a second drying chamber 5 connected to the discharge port of the first conveyor device 3, a second conveyor device 6 disposed in the second drying chamber 5, and an air inlet 51 disposed on one side of the outer shell of the second drying chamber 5;

[0023] Wherein, the blowing device 4 includes a blower 42 connected to the upper opening 21 of the first drying chamber 2 and a plurality of air nozzles 41 disposed on the top of the first drying chamber 2; the air inlet 51 is connected to a hot air supply device.

[0024] Specifically, a guide plate is connected between the feed bin 1 and the first drying chamber 2 to reduce the impact and friction when the aggregate enters the first drying chamber 2 from the feed bin 1. The first conveyor device 3 is disposed along the length direction in the first drying chamber 2, and the blowing device 4 is disposed directly above the first conveyor device 3. The blower 42 in the blowing device 4 can spray air through the plurality of air nozzles 41 onto the aggregate conveyed on the first conveyor device 3, so as to blow the moisture and impurities such as grease on the surface of the aggregate to the bottom of the first drying chamber, completing the preliminary drying of the aggregate. The air inlet 51 is disposed at the lower part of the housing of the second drying chamber 5 and is connected to the hot air supply device, so that the hot air enters the second drying chamber 5 through the air inlet 51 and penetrates the second conveyor device 6 from bottom to top, completing the secondary drying of the aggregate on the second conveyor device 6.

[0025] Optionally, in order to ensure that the air blown out by the blowing device 4 can fully contact the fresh bone, an air passage with a specific path can be set on the top of the first drying chamber 2 according to the size of the first drying chamber 2 and the aggregate distribution, and the air nozzles 41 are installed on the air passage to optimize the air flow distribution method to achieve an all-round blowing effect. Further, the air nozzles 41 can be selected as nozzles with adjustable angles to achieve a multi-angle blowing effect. Furthermore, a pressurizing device can be connected in the blowing device 4 to improve the drying effect.

[0026] The solution of this application performs segmented drying on the washed aggregates by setting up two drying chambers. In the first drying chamber 2, during the conveyance of the aggregates, the blowing device 4 disposed above the first conveying device 3 blows gas through the fan 42 and multiple air nozzles 41 towards the aggregates to carry away the moisture on the surface of the aggregates. In the second drying chamber 5, the hot air supply device is connected through the air inlet 51 to provide hot air flowing upward from bottom to top for the second conveying device 6 to dry the aggregates conveyed on the second conveying device 6 and remove the moisture inside them. The design of this solution enables the aggregates to receive different degrees of heat and air flow treatment at different stages, continuously drying the aggregates, which is conducive to more precisely controlling the drying process, avoiding problems such as over-drying or insufficient drying, and thus improving the drying efficiency and quality.

[0027] Continue to refer to Figure 2 , in one implementation, the first conveying device 3 includes a mesh belt conveyor; the high-efficiency energy-saving continuous aggregate drying system further includes: a funnel-shaped water storage tank 22 and a drain port 23 disposed at the bottom of the first drying chamber 2.

[0028] Specifically, the mesh belt conveyor can provide good support for the aggregates, preventing the gas pressure blown out by the air nozzles 41 from being too large and flushing the aggregates off the conveyor belt; and the mesh belt conveyor can allow the moisture on the surface of the aggregates to pass through the conveyor belt. It should be understood that in order to ensure the stability of the first conveying device 3, a mesh belt conveyor made of corrosion-resistant materials such as stainless steel or special alloy can be used. The funnel-shaped water storage tank 22 can effectively collect the moisture blown off the surface of the aggregates by the air, preventing it from overflowing everywhere and causing environmental pollution or equipment corrosion. A drain port 23 is provided at the bottom of the water storage tank 22, and the collected moisture can be smoothly discharged out of the system through a connecting pipe to keep the inside of the first drying chamber 2 clean and dry.

[0029] Continue to refer to Figure 1 , in one implementation, the top of the second drying chamber 5 is set to be arc-shaped; the high-efficiency energy-saving continuous aggregate drying system further includes: a suction device 7 connected to the top opening of the second drying chamber 5.

[0030] Specifically, the suction device 7 is used to timely discharge the humid and hot air generated in the second drying chamber 5 to prevent the humid and hot air from accumulating in the second drying chamber 5. The top of the second drying chamber 5 being set to be arc-shaped can guide the accumulated water vapor, further preventing the humid and hot air from accumulating at the top and dripping condensed water droplets onto the aggregates directly below, causing pollution. The types of equipment for the suction device 7 can be induced draft fans, dehumidifying fans, or circulating fans, etc., and this application does not limit this.

[0031] Continue to refer to Figure 1, in one implementation, the second conveying device 6 includes: a conveyor belt 61, transmission shafts 62 disposed at both ends of the conveyor belt 61, a drive motor 63 disposed on the support legs 52 of the second drying chamber 5, and a belt pulley 64 connecting the transmission shafts 62 and the drive motor 63.

[0032] Specifically, in this embodiment, the second conveying device 6 composed of the conveyor belt 61, the transmission shafts 62, the drive motor 63, and the belt pulley 64 ensures the stable and continuous transmission of the aggregate in the second drying chamber 5. By adjusting the rotation speed and power of the drive motor 63, precise control of the aggregate transmission speed can be achieved, so as to meet the drying requirements of aggregates of different sizes and types. In addition, on the basis of this embodiment, in one implementation, a support platform 53 for supporting the drive motor 63 is welded on the support legs 52. The welding and fixing method of the support platform 53 further ensures the stability and safety of the drive motor 63 during operation.

[0033] Continue to refer to Figure 2 , in one implementation, at least one observation window 54 is provided on one side of the outer shell of the second drying chamber 5.

[0034] In this embodiment, in order to facilitate the operator to monitor the drying situation in the second drying chamber 5 in real time, such as the flow state of the aggregate, the drying progress, and possible abnormal situations, etc., a plurality of observation windows 54 are provided on one side of the outer shell of the second drying chamber 5. Optionally, the observation window 54 is made of a transparent and high-temperature resistant material, such as tempered glass or high-temperature resistant resin, etc.

[0035] Continue to refer to Figure 2 , in one implementation, the high-efficiency energy-saving continuous aggregate drying system further includes: a discharging device 8 connected to the discharge port of the first conveying device 3 and the feed port of the second conveying device 6.

[0036] Specifically, in order to ensure that the aggregate can smoothly transition from the first drying chamber 2 to the second drying chamber 5 for further drying treatment, and reduce the loss and pollution of the aggregate during the transfer process, this embodiment also provides a discharging device 8 between the discharge port of the first conveying device 3 and the feed port of the second conveying device 6. The discharging device 8 can be an inclined guide plate or a discharging wheel.
