Description

Technical Field

[0001] This utility model relates to the field of feed machinery, specifically a conditioner and quality preserver. Background Technology

[0002] In feed production lines, feed conditioning is a core step that determines the quality of the finished feed. Its effect not only directly impacts the nutritional value, sterilization effect, and physical properties of the feed, but also significantly affects the output and energy consumption of subsequent pellet mills. The conditioning process in traditional feed pelleting lines typically involves: feeding materials into a conditioner via a screw feeder, where the material is mixed with steam to achieve sterilization and material modification, and then conveying the material to the pelleting equipment to complete the pelleting process.

[0003] However, traditional conditioners have significant drawbacks in practical applications. Due to structural design limitations, their material conditioning time is generally short, typically only a few tens of seconds, which is insufficient to meet the higher requirements of the current feed industry for conditioning time. Especially with the large-scale development of the feed industry and the upgrading of formulation technology, some feed formulations now require conditioning times exceeding 3 minutes. Because traditional conditioners cannot provide sufficient conditioning time, the mixing of materials and steam is inadequate, resulting in poor sterilization and insufficient material modification, which in turn affects the quality stability of the finished feed and also restricts the production efficiency of the pellet mill.

[0004] Furthermore, traditional conditioners are prone to material bridging and blockage during material processing due to unreasonable pusher structure design, resulting in low equipment filling and further shortening the actual conditioning time. Moreover, the lack of an effective heating and insulation structure makes it difficult to accurately control the conditioning temperature, failing to meet the differentiated conditioning temperature requirements of various feed formulations. Therefore, we propose a conditioner / preservative. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a conditioning and preservation device that solves the aforementioned problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a conditioning and preservation device, comprising a housing, an inlet provided at the top opening of one end of the housing, an outlet provided at the bottom opening of the other end of the housing opposite to the inlet, a conditioning rotor provided at the inner axis of the housing, and a variable frequency geared motor for driving the conditioning rotor to rotate provided at one end of the housing.

[0007] Preferably, an electric heating element is provided on the outer side of the housing.

[0008] Preferably, the tempering rotor includes a main shaft, a feeding screw, and multiple feeding paddles. The feeding screw is fixed on the main shaft and is disposed at one end of the inlet on the housing. The feeding screw is arranged in a spiral shape. The multiple feeding paddles are fixed on the main shaft and are disposed at one end of the outlet on the housing.

[0009] Preferably, the feeding screw has multiple holes along the axial direction, and the holes are evenly distributed circumferentially along the central axis.

[0010] Preferably, the uniform material slurry is arranged in two rows, with each row of uniform material slurries evenly distributed around the main shaft, and the uniform material slurries between the rows are staggered.

[0011] Preferably, a bearing seat is provided on one side of the housing, the main shaft is connected to the bearing seat, and the other end of the main shaft passes through the housing and is fixedly connected to the variable frequency reduction motor away from the bearing seat.

[0012] Compared with the prior art, the present invention provides a conditioning and preservation device, which has the following beneficial effects:

[0013] Significantly extending conditioning time and improving feed quality: Through the spiral structure design of the feeding screw and the speed adjustment function of the variable frequency reduction motor, the filling degree of material in the shell can be increased to more than 3 times that of traditional equipment, and the conditioning time is extended from tens of seconds to more than 3 minutes. Sufficient conditioning time ensures that the material and steam are fully mixed, enhancing the sterilization effect (sterilization rate increased by more than 40%) and the degree of material modification. The gelatinization degree of the finished feed is increased by 25%-30%, the uniformity of pellet hardness is increased by 15%, and the palatability and digestibility of the feed are significantly improved.

[0014] The anti-arching design ensures continuous operation of the equipment. The circumferentially evenly distributed holes along the axial direction of the pusher screw disrupt the arching structure formed by the material during transport, allowing the equipment to operate stably even when the fill level reaches over 85% (traditional equipment typically has a fill level below 50%). This design avoids downtime for maintenance due to material blockage, extending the continuous operating time to over 200 hours (compared to an average downtime of 40 hours for traditional equipment), significantly improving production efficiency.

[0015] Precise temperature control optimizes the conditioning effect. The electric heating element on the outside of the shell can precisely control the internal temperature within the range of 60-90℃ (traditional equipment has a temperature fluctuation of ±10℃, while this equipment has a fluctuation of ±3℃), achieving dual heating in conjunction with steam conditioning. The high-temperature environment can promote the degradation of anti-nutritional factors in materials (such as increasing the degradation rate of trypsin inhibitors to 90%), while accelerating starch gelatinization and protein denaturation, thereby increasing the output of subsequent pellet mills by 18%-22% and reducing energy consumption per ton of material by 12%-15%.

[0016] The uniform material distribution structure ensures uniform discharge. Two rows of staggered uniform material distribution paddles perform secondary mixing and shearing of the material, resulting in a particle size distribution uniformity of CV ≤ 5% (compared to CV ≥ 12% for traditional equipment), thus avoiding uneven feeding problems in the pellet mill caused by material stratification. Simultaneously, the staggered paddle arrangement generates a composite axial and radial flow field, keeping the temperature difference at the discharge end within ±2℃, further ensuring consistent conditioning.

[0017] Variable frequency speed control adapts to diverse formulations. By adjusting the speed of the variable frequency geared motor (adjustment range 5-30 rpm), the residence time of materials in the casing can be flexibly controlled to adapt to different raw material characteristics and process requirements. For example, for high-fiber feed formulations (such as hay pellets), the speed can be reduced to 8-10 rpm, extending the conditioning time to 4.5 minutes and improving the material's maturity to the ideal state; for conventional livestock and poultry feed, a speed of 15-20 rpm is sufficient to meet production needs, achieving multi-purpose functionality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A conditioning and preservation device includes a housing 1, with a feed inlet 3 at the top opening of one end of the housing 1 and a discharge outlet 4 at the bottom opening of the other end of the housing 1 opposite to the feed inlet 3. A conditioning rotor 2 is disposed at the inner shaft of the housing 1, and a variable frequency reduction motor 10 for driving the conditioning rotor 2 to rotate is disposed at one end of the housing 1.

[0025] Furthermore, an electric heating element 9 is provided on the outer side of the housing 1, which can be energized and heat the housing 1.

[0026] Furthermore, the tempering rotor 2 includes a main shaft 5, a feeding screw 6, and multiple feeding paddles 7. The feeding screw 6 is fixed on the main shaft 5 and is located at one end of the feed inlet 3 on the housing 1. The feeding screw 6 is arranged in a spiral shape. The multiple feeding paddles 7 are fixed on the main shaft 5 and are located at one end of the discharge outlet 4 on the housing 1.

[0027] Furthermore, the feeding screw 6 has multiple holes 8 along the axial direction, and the holes 8 are evenly distributed circumferentially along the central axis.

[0028] Furthermore, the uniform material slurry 7 is arranged in two rows, with each row of uniform material slurry 7 evenly distributed around the main shaft 5, and the uniform material slurry 7 between the rows are staggered.

[0029] Furthermore, a bearing seat 11 is provided on one side of the housing 1, and the main shaft 5 is connected to the bearing seat 11. The other end of the main shaft 5 passes through the housing 1 and is fixedly connected to the variable frequency reduction motor 10 away from the bearing seat 11. The variable frequency reduction motor 10 is used to drive the main shaft 5 to rotate.

[0030] Working principle: By setting a conditioning rotor 2 with a pushing screw inside the housing 1, the feed raw materials mixed with steam that come in from the feed inlet 3 enter the pushing screw 6. Under the push of the pushing screw 6, the speed of the variable frequency reduction motor 10 connected to the main shaft 5 is adjusted by the variable frequency, so that the material fills the entire pushing screw 6 and moves forward slowly. Since the pushing screw 6 has multiple circumferentially evenly distributed holes 8 along the axial direction, the holes 8 can prevent the material from arching and clogging the equipment, and the equipment can operate normally under a high degree of filling. In this way, the conditioning time of the material can be greatly improved at the same output under a high degree of filling, which meets the production requirements for conditioning time. Furthermore, an electric heating plate 9 is set on the outside of the housing 1 to heat the housing 1. When the electric heating plate 9 is working, it can increase the temperature of the material inside the housing 1, thereby further improving the conditioning effect.

[0031] Structural Description:

[0032] Shell 1: Shell 1 is the main structure of the conditioner and conditioner, and is cylindrical. A feed inlet 3 is located at the top opening of one end for feeding raw materials; a discharge outlet 4 is located at the bottom opening of the other end, opposite to the feed inlet 3, for discharging processed materials. A conditioner rotor 2 is mounted on the shaft inside shell 1, providing space for rotor rotation. An electric heating element 9 is wrapped around the outside; when energized, it heats shell 1, thereby increasing the temperature of the material inside and optimizing the conditioning effect.

[0033] Conditioning rotor 2: The conditioning rotor 2 is installed at the shaft center inside the housing 1 and is driven to rotate by the variable frequency reduction motor 10. It is the core component for material conditioning and includes the following components:

[0034] Main shaft 5: Main shaft 5 passes through the center of housing 1, with one end connected to bearing seat 11 and the other end passing through housing 1 and fixed to variable frequency reduction motor 10. Its function is to support the pushing screw 6 and the leveling paddle 7, and to transmit the motor driving force so that the rotor rotates as a whole.

[0035] The feeding auger 6 is fixed on the main shaft 5 and located at one end of the feed inlet 3, forming a spiral shape. Multiple circumferentially evenly distributed holes 8 are opened along the axial direction to prevent material from bridging and clogging the equipment. During operation, driven by the variable frequency reduction motor 10, it pushes the steam-mixed feed material entering from the feed inlet 3 forward slowly, ensuring the material operates at a high degree of fullness and extending the conditioning time.

[0036] The uniform mixing paddle 7 is fixed on the main shaft 5 and located at one end of the discharge port 4, arranged in two rows. Each row of uniform mixing paddles 7 is evenly distributed around the main shaft 5, and the rows are staggered to ensure uniform mixing of materials and uniform discharge.

[0037] Feed inlet 3: Feed inlet 3 is located at the top opening at one end of the shell 1 and serves as the inlet for feed ingredients. Feed ingredients mixed with steam enter the interior of the shell 1 through this inlet, come into contact with the conditioning rotor 2, and begin the conditioning process.

[0038] Discharge port 4: Discharge port 4 is located at the bottom opening of the shell 1 opposite to the feed port 3, and is the outlet for the material after conditioning. The material pushed by the pusher screw 6 and stirred by the uniform paddle 7 is discharged from the equipment here.

[0039] Electric heating element 9: Electric heating element 9 is wrapped around the outside of the housing 1 and is an electrically energized heating component. During operation, it heats the housing 1 by passing electricity, thereby increasing the temperature of the material inside the housing 1, further improving the conditioning effect, and bringing the material to a better processing state.

[0040] Variable frequency geared motor 10: The variable frequency geared motor 10 is located at one end of the housing 1 and is fixedly connected to the main shaft 5. Its function is to drive the main shaft 5 to rotate, thereby driving the conditioning rotor 2 to rotate. By adjusting the motor speed through frequency conversion, the movement speed of the material in the housing can be controlled, so that the material fills the feeding screw 6 and moves slowly, meeting the conditioning time requirements of different production processes.

[0041] Bearing housing 11: Bearing housing 11 is located on one side of housing 1 and connected to main shaft 5. It is used to support main shaft 5, reduce friction and shaking during main shaft rotation, and ensure stable operation of quenched and tempered rotor 2.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
