Description

Technical Field

[0001] This utility model relates to the field of dryers, and in particular to a speed regulating device for a low-temperature roasted grain dryer. Background Technology

[0002] In the processing of baked pet food, a conveyor belt inside the dryer propels the semi-finished pet food forward. During this process, the moisture content of the semi-finished pet food gradually decreases, eventually resulting in a crisp texture. The speed of the conveyor belt determines the time the finished pet food spends in the dryer. Because the finished pet food needs to achieve a certain dehydration rate, if the conveyor belt moves too fast, the baking temperature must be increased, which will affect the texture of the finished pet food. For example, if the semi-finished pet food needs to pass through the dryer in 30 to 60 minutes, to ensure that the moisture content is reduced by about 10% to 15%, the internal temperature of the dryer needs to be raised to 125 to 150 degrees Celsius, resulting in a final pet food that is not crisp. Furthermore, in traditional processes, the speed of the conveyor belt is not adjustable, and the final moisture content of different types of semi-finished pet food can only be controlled by adjusting the temperature, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a speed control device for a low-temperature roasted grain dryer to solve the problems existing in the prior art.

[0004] The present invention provides a speed control device for a low-temperature roasted grain dryer, characterized in that it includes a motor, a transmission module, a chain plate, and a speed control module.

[0005] The motor is installed outside the dryer and is driven by the transmission module to connect to the chain plate; the chain plate is installed inside the dryer; the transmission module spans the dryer, with one end connected to the motor and the other end connected to the chain plate; the motor is driven by the transmission module to connect to the chain plate; the speed control module is electrically connected to the power supply and the motor.

[0006] Furthermore, the transmission module includes a main sprocket, a driven sprocket, and a transmission chain; the driven sprocket is fixed to the output shaft of the motor, and the main sprocket drives the chain plate.

[0007] Furthermore, the diameter ratio of the master sprocket to the slave sprocket is at least 5.5 times.

[0008] Furthermore, the diameter of the master sprocket is 90 mm, and the diameter of the slave sprocket is 495 mm.

[0009] Furthermore, the main sprocket has fewer than 18 teeth.

[0010] Furthermore, the main sprocket has 9 teeth.

[0011] Furthermore, the speed control module is a frequency converter; the frequency converter includes an input terminal and an output terminal; the input terminal is connected to the power supply, and the output terminal is electrically connected to the motor.

[0012] Furthermore, the speed control module also includes a user interaction submodule; the frequency converter also includes a control terminal; the user interaction submodule is electrically connected to the control terminal.

[0013] Furthermore, the user interaction submodule is a touch screen; the touch screen is independently powered and electrically connected to the control terminal of the frequency converter.

[0014] Furthermore, the inverter is model FC-360H1K from Danfoss (China) Investment Co., Ltd., and the touch screen is model MT8103i from Shenzhen Weintek Technology Co., Ltd.

[0015] This invention relates to a low-temperature pet food drying machine. By modifying the transmission ratio of the transmission module and adding an independent speed control module, the speed control device significantly reduces the chain plate's operating speed compared to existing technologies. This extends the time the semi-finished pet food is in the drying machine, thus lowering the baking temperature and ensuring product quality, maintaining a crisp texture. Compared to existing technologies where the same semi-finished pet food requires 80 to 200 minutes of drying time, the internal temperature of the drying machine can be set to 90 to 120 degrees Celsius to achieve a 10-15% moisture reduction. Furthermore, by adjusting the speed control module, the baking process can be dynamically intervened, ensuring consistent pet food product quality. Attached Figure Description

[0022] The specific embodiments of this utility model will be described below with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 2 and Figure 3 This utility model discloses a speed regulating device for a low-temperature roasted grain dryer. In a preferred embodiment, it consists of a motor 1, a main sprocket 2, a driven sprocket 3, a transmission chain 4, a chain plate 5, and a frequency converter 6.

[0024] The chain plate 5 is located inside the dryer 8. The semi-finished pet food is placed on the chain plate 5 and is slowly moved forward inside the dryer 8 by the chain plate 5. During the forward movement, the warm air in the dryer 8 continuously dries the semi-finished pet food, evaporating the moisture and drying it at a low temperature and low speed.

[0025] The chain plate 5 is powered by a motor 1 located outside the dryer 8. A transmission module, consisting of a main sprocket 2, a driven sprocket 3, and a drive chain 4, transmits power from the motor 1 to the chain plate 5, driving its rotation. Specifically, the driven sprocket 3 is fixed to the output shaft of the motor 1, while the main sprocket 2 is connected to the chain plate 5. Power is transmitted between the main sprocket 2 and the driven sprocket 3 via the drive chain 4. The transmission module is installed across the dryer 8, with one end connected to the motor 1 and the other end connected to the chain plate 5. In addition to transmitting power, the transmission module also adapts the operating speeds of the motor 1 and the chain plate 5. Generally, the operating speed of the motor 1 is much higher than the required speed of the chain plate 5; therefore, the main sprocket 2, driven sprocket 3, and drive chain 4 are used to match the speeds.

[0026] To ensure the finished pet food meets standards, the operating speed of the chain plate 5 has an upper limit. Therefore, the diameter ratio of the main sprocket 2 to the driven sprocket 3 must be at least 5.5 times, and the main sprocket 2 must have fewer than 18 teeth. In this embodiment, the diameter of the main sprocket 2 is 90 mm, and the diameter of the driven sprocket 3 is 495 mm, which is 5.5 times that of the main sprocket 2. The main sprocket has 9 teeth.

[0027] Please see Figure 4This invention also includes a speed control module, which is electrically connected to the power supply and the motor 1, and is used to adjust the speed of the motor 1. In this preferred embodiment, the speed control module is specifically implemented as a frequency converter 6 (FC-360H1K from Danfoss (China) Investment Co., Ltd.), belonging to the electrical control part, which includes an input terminal 61, an output terminal 62, and a control terminal 63. The input terminal 61 of the frequency converter 6 is connected to the power supply, and the output terminal 62 is connected to the motor 1. The control terminal 63 of the frequency converter 6 receives control commands from the user interaction submodule, and then sends power from the output terminal 62 to the motor 1 in different modes according to the control commands, thereby controlling the speed of the motor 1. Specifically, the user interaction submodule is a touch screen 7 (MT8103i from Shenzhen Weintek Technology Co., Ltd.), which is connected to the control terminal 63 of the frequency converter 6 via the TCP / IP protocol. The touch screen 7 is independently powered and does not obtain power from the frequency converter 6. The operator can conveniently and remotely adjust the parameters of the frequency converter 6 through the touch screen 7, thereby adjusting the speed of the motor 1.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
