Description
Technical Field
[0001] The utility model relates to the technical field of milk replacer processing, in particular to the field of milk replacer drying, and specifically refers to a milk replacer dryer with automatic temperature control. Background Technique
[0002] Milk replacer is a stable product made from high-quality milk source products, plant proteins and other raw materials through modern processing technologies such as atomization and emulsification. As a substitute for cow milk and goat milk, it contains nutrients such as energy, protein, macro and trace elements required for the growth and development of young animals such as calves and lambs. In the drying process of milk replacer, spray drying towers are usually used for drying. Spray drying towers are drying equipment widely used in the fields of chemical industry, food, medicine, etc. Its working principle is to disperse the liquid into fine droplets through a sprayer, contact with hot air, and quickly evaporate the water through heat transfer and evaporation to obtain dry powder or granular products.
[0003] However, the existing milk replacer dryers have many deficiencies in temperature control. Traditional milk replacer dryers mostly rely on manual experience or simple temperature controllers to adjust the internal temperature. This method is not only inefficient, but also difficult to ensure the temperature stability during the drying process, and it is easy to cause inconsistent quality of milk replacer. For example, if the temperature is too high, the milk replacer may be scorched or its quality may decline due to overheating; if the temperature is insufficient, it may lead to incomplete drying, affecting the shelf life of the product. Secondly, the temperature detection devices in the existing dryers are often directly exposed to high-temperature hot air, which will affect the accuracy of temperature detection. The direct impact of the hot air flow may cause the temperature detector reading to be too high or fluctuate, thus unable to truly reflect the temperature condition inside the dryer. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the utility model provides a milk replacer dryer with automatic temperature control, which realizes automatic temperature monitoring and adjustment inside the dryer to ensure that the milk replacer is always within the optimal temperature range during the drying process.
[0005] The utility model is realized through the following technical solutions. A milk replacer dryer with automatic temperature control is provided, including a housing. An inlet pipe is installed above the housing, and the inlet pipe extends into the housing. An atomizing nozzle connected to the inlet pipe is installed inside the housing. The housing is communicated with a plurality of hot air pipes, and the hot air pipes are connected to a heating device. A plurality of connecting rods are installed on the inner wall of the housing, and a housing is fixedly connected to the end of the connecting rod far away from the inner wall of the housing. A temperature detector is installed inside the housing. The temperature detector is electrically connected to a control center, and the heating device is electrically connected to the control center. An outlet is opened at the lower end of the housing, and a reciprocating screen is installed inside the housing, and the reciprocating screen is located above the outlet.
[0006] In this utility model, the milk replacer liquid is discharged into the shell through the liquid inlet pipe, heated by a heating device, and the hot air is blown into the shell through the hot air pipe. The atomizing nozzle can atomize the liquid, and the atomized liquid exchanges heat with the hot air to form milk replacer. The temperature detector can detect the temperature inside the shell. The design of the housing enables the temperature detector to be installed inside the housing, thus preventing the temperature detector from being directly blown by the hot air and affecting the detection effect. The temperature detector transmits the detected temperature to the control center, and the control center controls the temperature of the hot air produced by the heating device, thereby controlling the temperature inside the shell. The screen can isolate the non-powdered liquid above the screen. When the liquid falls onto the screen, it will contact the powder to form balls and cannot fall below the screen, thus ensuring the quality of the milk replacer.
[0007] As an optimization, the housing includes a top cover and a mounting frame. The top cover is conical, the mounting frame is fixedly connected below the top cover, and the lower end of the mounting frame is open. The temperature detector is installed on the inner wall of the mounting frame. With this optimized solution, the conical design can reduce the accumulation of materials at the top of the housing and reduce the cleaning difficulty.
[0008] As an optimization, the reciprocating screen includes a screen slidably connected to the shell. The rear end of the screen is hinged with a rocker. A sealing shell is installed at the rear end of the shell. A driving motor is installed inside the sealing shell, and a rotating disk is fixedly connected to the output shaft of the driving motor. There are protrusions on the rotating disk, and the rear end of the rocker is rotatably connected to the protrusions. With this optimized solution, the screen can reciprocate back and forth in the shell in the front-rear direction, so as to screen out the dried milk replacer.
[0009] As an optimization, a three-way hopper is installed at the lower end of the liquid inlet pipe. The three-way hopper has three liquid outlets, and an atomizing nozzle is installed at each of the three liquid outlets. With this optimized solution, the milk replacer liquid can be sprayed more evenly in the dryer, improving the atomization uniformity and drying efficiency.
[0010] As an optimization, the hot air pipes are divided into several groups. Each group of hot air pipes is distributed along the up-down direction of the shell, and several hot air pipes in the same group are distributed along the circumferential direction of the shell. With this optimized solution, this layout ensures that the hot air can enter the dryer internally in all directions and evenly, further improving the heat exchange efficiency and drying uniformity.
[0011] As an optimization, the temperature detector extends horizontally, and the sensor of the temperature detector is located at the center of the mounting frame. With this optimized solution, it can more accurately reflect the actual temperature inside the dryer, improving the accuracy of temperature detection.
[0012] The beneficial effects of the present utility model are as follows: By installing a temperature detector and a control center and electrically connecting them to the heating device, the present utility model realizes automatic temperature monitoring and regulation inside the dryer, which can ensure that the milk replacer powder is always within the optimal temperature range during the drying process, avoiding quality degradation caused by overheating or incomplete drying caused by insufficient temperature, thus improving product quality and drying efficiency.

[0020] As Figures 1 to 4 shown, an automatic temperature-controlled milk replacer dryer of the present utility model includes a housing 1. The housing 1 extends in the up and down direction. The middle and upper sections of the housing 1 are cylindrical, and the lower section of the housing 1 is rectangular.

[0021] The housing 1 is communicated with a plurality of hot air pipes 9. The hot air pipes 9 are installed on the side wall of the housing 1 and extend into the housing 1. The hot air pipes 9 are divided into several groups. Each group of hot air pipes is distributed along the up and down direction of the housing, and several hot air pipes in the same group are distributed along the circumference of the housing. The hot air pipes are connected to a heating device.
[0022] A number of connecting rods 4 are installed on the inner wall of the housing 1. One end of the connecting rod away from the inner wall of the housing is fixedly connected to a housing shell 5. Each of the four corners of the housing shell 5 is connected to a connecting rod 4. The connecting rod 4 extends obliquely outward from the housing shell to the inner wall of the housing 1 and is fixedly connected to the inner wall of the housing 1. The upper end surface of the connecting rod 4 is conical. A wire conduit is fixedly connected to the front end surface of the housing shell. The wire conduit is hollow and is provided with a heat insulation layer. The wire conduit extends to the outside of the housing.
[0023] The housing shell 5 includes a top cover 52 and a mounting frame 51. The top cover is conical with the cone tip facing upward. The mounting frame is fixedly connected below the top cover and extends in the up and down direction. The lower end of the mounting frame is open. The connecting rod is fixedly connected to the outer wall of the mounting frame. A temperature detector 6 is installed inside the housing shell. The temperature detector is installed on the inner wall of the mounting frame 51 and is fixedly connected to the front inner wall of the mounting frame 51. The temperature detector 6 extends horizontally. The sensor of the temperature detector 6 is located at the center of the mounting frame. A micropore penetrating the mounting frame is opened on the front inner wall of the mounting frame 51. The wire conduit communicates with the housing shell 5 through the micropore. The wire of the temperature detector 6 extends to the outside of the housing 1 through the wire conduit. The temperature detector is electrically connected to a control center. The heating device is electrically connected to the control center.
[0024] An outlet is opened at the lower end of the housing. A reciprocating screen 7 is installed inside the housing. The reciprocating screen is located above the outlet. The reciprocating screen includes a screen 71 slidably connected to the housing. The screen 71 extends in the front and back directions. The screen is slidably connected to the lower section of the housing 1. Guide rails for the screen to slide are fixedly connected to the left inner wall and the right inner wall of the lower section of the housing 1. The front and back ends of the screen extend to the outside of the housing 1. Sealing shells are installed at the front and back ends of the housing. The front and back ends of the screen are located inside the sealing shells. The sealing shells can increase the sealing performance of the housing at the installation location of the reciprocating screen.
[0025] A driving motor is installed inside the rear sealing shell. The driving motor is fixedly connected to the inner wall of the sealing shell and extends in the up and down direction. The output shaft of the driving motor is fixedly connected to a rotating disk 74. The rotating disk is circular. The center of the lower end of the rotating plate is fixedly connected to the output shaft of the driving motor. There are protrusions on the rotating disk. The protrusions are cylindrical and are fixedly connected to the upper end surface of the rotating disk and extend in the up and down direction. A rocker 73 is hinged to the rear end of the screen.

The rocker extends in the front and back directions. The hinge axis of the rocker 73 and the articulated frame 72 extends in the up and down direction. A groove extending in the up and down direction is opened on the lower end surface of the rear end of the rocker. The protrusion is located inside the groove, and the outer wall of the protrusion fits with the inner wall of the groove, so that the rear end of the rocker is rotatably connected to the protrusion.
[0026] During the use of this embodiment, the liquid milk replacer enters the three-compartment hopper 8 through the liquid inlet pipe 2. After being split by the three-compartment hopper 8, the liquid milk replacer is atomized and sprayed evenly inside the housing 1. The heating device sprays the hot air produced through a number of hot air pipes 9 evenly into the housing 1. The milk replacer inside the housing 1 exchanges heat with the hot air for drying. The temperature detector 6 inside the housing 5 can detect the temperature inside the housing 1 and feed the detected temperature back to the control center. The control center controls the output power of the heating device according to the received temperature signal, so as to keep the temperature inside the housing within an appropriate range. After heat exchange, the milk replacer falls onto the screen. The motor operates to drive the rotating disk 74 to rotate. As the rotating disk 74 rotates, the protrusions make a circular motion. The protrusions drive the rocker 73 to displace, so that the screen 71 makes a reciprocating motion, causing the dried milk replacer to fall below the screen. The incompletely dried milk replacer falling onto the screen will agglomerate with the completely dried milk replacer, thus preventing the incompletely dried milk replacer from falling below the screen, and ensuring the quality of the milk replacer discharged from the housing.
