Description

Technical Field

[0001] This utility model relates to the field of food processing, and in particular to a food processing raw material drying device. Background Technology

[0002] Drying food ingredients is an important step in food processing, aimed at removing moisture from food to facilitate storage and transportation. The drying process effectively inhibits microbial growth and extends the shelf life of food.

[0003] Chinese Patent Announcement No. CN 220911874 U describes a "drying device for raw materials of fast food processing", in which an air outlet pipe for conveying hot air is installed on the top of the drying barrel, and a fan is added to further transmit the hot air, making the hot air more dispersed, so as to realize the drying operation of food raw materials.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] This drying method involves hot air entering the food raw material pile from the outside. To balance the pressure inside the drying drum, an air outlet is needed. Regarding the location of this air outlet, the bottom position is preferred, based on the location of the air inlet, to ensure that the hot air can penetrate the food raw material pile. However, this can easily lead to the food raw material blocking the air outlet. If the amount of gas discharged from inside is small, it will also directly affect the air intake.

[0006] Therefore, it is necessary to provide a new food processing raw material drying device to solve the above-mentioned technical problems. Utility Model Content

[0026] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 This utility model provides a food processing raw material drying device, which includes a drying barrel 1, an upper end cover 2 fixed to the upper end of the drying barrel 1, a feeding port 3 provided on the upper end cover 2, and a discharging port 4 provided at the lower end of the drying barrel 1.

[0031] A mounting base 5 is also fixed on the upper end cover 2, and it also includes:

[0032] The stirring mechanism 6 consists of a drive unit 61 mounted on the mounting base 5 and a stirring guide unit 62 rotating inside the drying barrel 1. The stirring guide unit 62 includes a second drive shaft 621 rotatably connected to the upper end cover 2 and multiple sets of stirring rods 622 fixed on the second drive shaft 621. The second drive shaft 621 and the stirring rods 622 have communicating cavities inside, and multiple air outlets 623 are provided on the stirring rods 622.

[0033] The intake pipe 8 is fixed on the mounting base 5. The second drive shaft 621 and the intake pipe 8 are connected by a rotary joint 7. The intake pipe 8 is connected to the internal cavity of the second drive shaft 621. A connecting pipe 9 is also fixed on the intake pipe 8.

[0034] It should be noted that this type of drying device still retains a stirring structure. During the drying process of raw materials, stirring is used to prevent the raw materials from piling up, which helps the hot air to penetrate and improves the efficiency of drying the raw materials.

[0035] The stirring and guiding section 62 is the main stirring structure, which includes a second drive shaft 621 and multiple stirring rods 622. Both the second drive shaft 621 and the stirring rods 622 have cavities inside, which can guide the hot air. The stirring rods 622 have air vents 623 for discharging the hot air. Therefore, during the stirring of the raw materials using the stirring rods 622, hot air can also be drawn out from inside the food raw material pile, allowing the hot air to penetrate the food raw material pile better, thereby increasing the efficiency of food drying and making the drying more uniform.

[0036] The intake pipe 8 and the second drive shaft 621 are connected by a rotary joint 7, thereby realizing the connection between the intake pipe 8 and the second drive shaft 621, and also ensuring that the second drive shaft 621 can rotate. A pipe 9 is provided on the intake pipe 8, which is used to connect an external hot air blower, thereby introducing hot air into the cavity inside the second drive shaft 621 and the stirring rod 622.

[0037] During the drying process, the feed inlet 3 can be opened, and at this time the feed inlet 3 can be used as an air outlet to balance the pressure inside the drying drum 1.

[0038] In the embodiments of this utility model, please refer to Figure 3 The drive unit 61 includes a motor 611 fixed on the mounting base 5. The output end of the motor 611 is fixed with a first transmission shaft 612 arranged concentrically. A drive sprocket 613 is fixed on the first transmission shaft 612.

[0039] A concentric driven sprocket 614 is fixed on the second drive shaft 621, and a drive chain 615 is provided between the driven sprocket 614 and the driving sprocket 613.

[0040] It should be noted that when the drive unit 61 drives the second transmission shaft 621 to rotate, the motor 611 can directly drive the first transmission shaft 612 to rotate, which in turn drives the drive sprocket 613 to rotate. The driven sprocket 614 is fixed on the second transmission shaft 621 and is connected to the drive sprocket 613 by a transmission chain 615. Therefore, through the transmission action, the second transmission shaft 621 can be directly driven to rotate, so that the stirring rod 622 can be used to stir the raw materials.

[0041] In the embodiments of this utility model, please refer to Figure 4 The stirring rod 622 is arc-shaped, with the outer arc surface being the surface on which the stirring rod 622 rotates and moves forward, while the vent 623 is located on the inner arc surface. The cross-section of the stirring rod 622 is triangular.

[0042] It should be noted that the stirring rod 622 is designed in an arc shape, and the air outlet 623 is located on the inner arc surface. Therefore, when the stirring rod 622 is used to stir the food raw materials, it can prevent the residue from blocking the air outlet 623 and ensure the normal operation of the drying process.

[0043] The cross-section of the stirring rod 622 is triangular, with its outer arc surface corresponding to one corner. Therefore, the resistance encountered by the stirring rod 622 during rotation is smaller, and the rotation effect of the second drive shaft 621 is better. Its inner arc surface corresponds to a plane, and the area at that position is larger, which can increase the working range of the stirring rod 622 and improve the stirring effect on the raw materials.

[0044] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0045] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
