Description

Technical Field

[0001] The invention relates to the technical field of food processing devices, in particular to a drum powder coating machine with an automatic crushing process for wet powder agglomerates. Background Art

[0002] Currently, drum coating machines are primarily used for coating meat and seafood products such as popcorn chicken, fried chicken, and crispy pork. Because they knead marinades, the mixing of the slurry and powder inevitably results in wet powder lumps during operation. Once wet powder lumps form, they become increasingly agglomerated during the powder circulation process, resulting in a higher defective rate. Subsequent process steps require additional manual screening, increasing labor costs and reducing production capacity. Extended working hours can also lead to machine blockage and poor operation, affecting the coating effect and requiring downtime for processing. This wastes front-end workers' time and reduces work efficiency, while lumps screening also results in significant waste of raw material costs.

[0003] However, as the existing devices are used in production, the shortcomings of this technology are gradually exposed, mainly in the following aspects:

[0004] First, the lumps screened out by conventional powder coating machines during the production process will eventually be thrown away or disposed of, causing waste and increasing production costs.

[0005] Second, the aperture of the vibrating screen of the conventional powder screening device is large. When powder agglomerates during the production process, the material becomes too sticky during crushing, causing blockage during the crushing process.

[0006] Third, the powder leakage distance of conventional roller powder coating machines is too long, and the powder leakage pattern is diamond-shaped. During the production process, the powder on the surface of the coated product is scratched off, thereby affecting the powder coating rate of the product and producing too many defective products.

[0007] Fourth, the powder return device of the conventional roller powder loading machine is a mesh belt, which has a short service life. Over time, the mesh belt will deform, resulting in untimely powder return and accumulation on the mesh belt. Increasing the tension of the mesh belt will easily accelerate the deformation of the mesh belt or cause the mesh belt to be scrapped. Some powder will clump when the mesh belt returns the powder.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

DETAILED DESCRIPTION

[0039] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0040] like Figures 1 to 7 As shown, the drum powder coating machine with the automatic crushing process for wet powder agglomerates comprises a product input device 1 , and an output end of the product input device 1 is connected to a product powder coating device 2 .

[0041] The product powder coating device 2 is provided with a powder discharge port 9 and a product discharge port 10 , and the product discharge port 10 is connected to the product output device 3 .

[0042] The powder discharge port 9 is connected to the agglomeration screening device 4 , which is provided with a powder discharge port and an agglomeration discharge port. The agglomeration discharge port is connected to the agglomeration crushing device 5 , and the output end of the agglomeration crushing device 5 is connected to the product input device 1 .

[0043] The working principle of the agglomeration crushing device 5 is that there are several combined blades rotating at high speed in the agglomeration hopper, and the size of the agglomerates is crushed by the number of loading and unloading blades. After the crushing is completed, the product is transported by the conveyor to the feed port 18 of the input device 1, which effectively reduces the waste of powder and reduces the cost of powder raw materials.

[0044] The powder discharge port is connected to a powder recovery device.

[0045] The product powder coating device 2 includes a rotating and tilted rotating drum 7, a separation drum 8 is fixedly connected to the lower port of the drum 7, a powder discharge port 9 is arranged on the wall of the separation drum 8, and a product discharge port 10 is the lower port of the separation drum 8.

[0046] The powder leakage outlet 9 includes a plurality of long strip powder leakage holes 19 circumferentially arranged on the separation cylinder 8 .

[0047] Several strip-shaped powder leakage holes 19 are arranged obliquely.

[0048] The powder leakage part of the roller 7 is shortened, and the original diamond hole is changed to a long strip, which reduces the friction between the powder-coated material and the powder leakage hole of the roller 7, reduces the formation of lumps, improves the appearance of the product, increases the powder coating amount of the product, improves the product yield, and increases economic benefits.

[0049] The product input device 1 comprises a rotatably arranged product input mesh belt 6 , the discharge port of which extends into the inlet port of the drum 7 .

[0050] The agglomeration screening device 4 includes a vibrating agglomeration screening plate 15 , and a powder recovery belt 16 is rotatably installed below the agglomeration screening plate 15 .

[0051] A vibration motor 13 is also fixed to the side wall of the agglomeration screening plate 15 .

[0052] The agglomeration screening plate 15 is evenly distributed with vibrating screen holes with a diameter of 14 mm. By reducing the aperture of the vibrating screen to 14 mm, the agglomerates screened out along with some dry powder enter the agglomeration crushing device 5 for crushing, thereby reducing blockage in the crushing process caused by the crushing material being too sticky, and reducing the phenomenon of stopping the machine for cleaning due to blockage during the production process, thus realizing continuous online production and greatly improving output. It also reduces the waste of time and labor.

[0053] The powder recovery belt 16 is a belt without holes. It is changed from a mesh belt type to a belt type, which effectively increases the service life and is more convenient to clean. By replacing the small speed ratio reducer, the powder return speed is faster and more conducive to powder circulation. When the mesh belt drags the powder back, it is easy to agglomerate during the powder return process, which affects the powder coating effect and appearance of the product. After changing to a belt type, the powder agglomeration phenomenon will not occur during the powder return process.

[0054] The product output device 3 includes a product output mesh belt 11 rotatably arranged below the product discharge port 10 , and a vibration mechanism for vibrating the product conveying mesh belt is also connected to the product conveying mesh belt.

[0055] The vibration mechanism includes a fixed motor 13, the output shaft of the motor 13 is connected to an eccentric vibration block 12 that frictionally contacts the mesh belt portion located above.

[0056] A recovery hopper 14 is provided below the product output mesh belt 11 to collect the powder that falls from the product output mesh belt 11 .

[0057] The motor 13 is located in the area between the upper and lower parts of the product output mesh belt 11.

[0058] The discharge end of the powder recovery belt 16 extends into the product input device 1 , so as to realize the circulation and transportation of the powder to the product input device 1 .

[0059] The discharging end of the agglomeration screening plate 15 is tilted downward and fixedly connected with an agglomeration outlet tube 17 .

[0060] The agglomerate outlet tube 17 is located above the feed inlet 18 of the agglomerate crushing device 5 .

[0061] The discharge port of the agglomeration breaking device 5 is connected to the feed port 18 of the product input device 1 .

[0062] The recovered powder is introduced into the product input device 1 through the discharge end of the powder recovery belt 16 and the discharge end of the agglomeration crushing device 5. As the powder in the product input device 1 increases, the powder is introduced to the guide roller on the right side by using the product input mesh belt 6 at the bottom. As the powder at the guide roller on the right side increases, the product input mesh belt 6 lifts the powder upward and transports it to the drum.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
