Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to an agglomerated instant granule spray dryer. Background Art

[0002] A spray dryer is a type of continuous atmospheric pressure dryer. It draws ambient air through a blower and into an air heater, raising the air temperature to approximately 160°C before feeding it into a drying tower. The liquid material to be dried is pumped into an atomizer by a pressure pump. The liquid is sprayed out as a mist and mixes with the hot air. The material particles absorb the heat, instantly evaporating the water and forming a powder that falls downward. Coarse particles fall into the conical bottom of the drying tower and are discharged. This dryer is suitable for drying heat-sensitive liquids, suspensions, and viscous liquids, such as milk, eggs, tannins, and pharmaceuticals.

[0003] Before the product is formed, the materials need to be stirred to obtain raw materials. Then, due to the high humidity of the raw materials, they need to be dried in a spray dryer before being sent to the next process.

[0004] When the existing spray dryer is working, the material is directly introduced into the spray dryer manually. Some materials are in a state of stratification and agglomeration, and direct introduction affects the quality of the finished product. Utility Model Content

[0024] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides an agglomerated instant granule spray dryer, comprising a spray dryer body 1, a material processing tank 2 and a support leg 3. The top of the material processing tank 2 is fixedly connected to a drive motor 5 through a mounting frame, the bottom end of the drive motor 5 is fixedly connected to a drive gear 6, the outer wall of the drive gear 6 is meshed with a transmission gear 7, and the outer wall of the top end of the transmission gear 7 is connected to an auxiliary rotating rod 9 through a transmission belt 8.

[0028] The top ends of the transmission gear 7 and the auxiliary rotating rod 9 are both provided with pulleys adapted to the transmission belt 8 , and one end of the connecting rod 11 away from the auxiliary rotating rod 9 is fixedly connected to the auxiliary stirring teeth 12 .

[0029] The top of the auxiliary rotating rod 9 is rotatably connected to the top of the inner wall of the material processing tank 2. The outer wall of the auxiliary rotating rod 9 is fixedly connected to a connecting rod 11. The bottom and upper surfaces of the connection between the connecting rod 11 and the auxiliary rotating rod 9 are provided with a shaft sleeve 13. The outer wall of the auxiliary rotating rod 9 is sleeved with a heating resistor 14, and the outer wall of the heating resistor 14 is sleeved with a corundum protective shell 15. The use of multiple sets of auxiliary rotating rods 9 and heating resistors 14 ensures more uniform mixing and heating of the materials.

[0030] The corundum protective shell 15 can provide good protection for the heating resistance wire 14 and ensure that the heat on the heating resistance wire 14 can be quickly transferred to the material processing tank 2.

[0031] The top ends of the heating resistor wire 14 and the corundum protective shell 15 are both fixedly connected to the top of the inner wall of the material processing tank 2, while the bottom ends of the heating resistor wire 14 and the corundum protective shell 15 are both rotatably connected to the top of the shaft sleeve 13. The coordinated use of the heating resistor wire 14, the corundum protective shell 15, and the shaft sleeve 13 ensures that the heat from the heating resistor wire 14 is evenly and quickly transferred to the interior of the material processing tank 2 without affecting the stirring effect provided by the auxiliary rotating rod 9. This ensures that the temperature of the material in the material processing tank 2 matches that of the interior of the spray dryer body 1, does not affect the normal drying operation of the spray dryer body 1, and improves operating efficiency.

[0032] Example 2

[0033] like Figure 1-5 As shown, based on Example 1, the present invention provides a technical solution: preferably, the bottom end of the driving motor 5 is fixedly connected to a central stirring rod 10 located inside the spray dryer body 1.

[0034] The bottom end of the auxiliary rotating rod 9 is rotatably connected to a support frame 16 , and the outer wall of the support frame 16 is fixedly connected to the inner wall of the material processing tank 2 .

[0035] The top of the support leg 3 is fixedly connected to the outer wall of the material processing tank 2, while the bottom of the support leg 3 is fixedly connected to the outer wall of the spray dryer body 1. A feed hopper 4 is fixedly connected to the top of the material processing tank 2. A temperature monitoring device is installed on the material processing tank 2 to monitor the temperature of the material inside the material processing tank 2 in real time. Once the temperature reaches the appropriate range, matching the temperature inside the spray dryer body 1, the material processing tank 2 is opened and the material is transferred to the spray dryer body 1 for subsequent processing.

[0036] The following is a detailed description of the working principle of the agglomerated instant granule spray dryer.

[0037] like Figure 1-5As shown, when in use, the material is put into the material processing tank 2 through the feed hopper 4, and then the drive motor 5 is started, so that the drive motor 5 drives the central stirring rod 10 to stir the material, and at the same time, drives the transmission gear 7 to rotate through the drive gear 6, and the transmission gear 7 drives the auxiliary rotating rod 9 to rotate through the transmission belt 8, and the auxiliary rotating rod 9 drives the connecting rod 11 and the auxiliary stirring teeth 12 to rotate, so that the material in the material processing tank 2 is fully stirred and mixed. At the same time, while the auxiliary rotating rod 9 stirs the material, the heating resistance wire 14 is energized and started to preheat the material. Since the heating resistance wire 14 is inserted into the material as a whole, the heat generated by it can be quickly and fully transferred to the material.

[0038] It should be noted that, in this article, the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or still includes elements that are inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element. The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
