Description

Technical Field

[0001] This utility model belongs to the technical field of packaging equipment, specifically relating to a rice packaging device. Background Technology

[0002] Rice packaging is an essential step in rice processing. After the rice is hulled and sorted, it needs to be packaged to facilitate transportation and sales. However, existing rice packaging equipment still has some shortcomings that affect production.

[0003] Firstly, existing rice packaging equipment lacks a drying device, which easily leads to the rice becoming damp during the packaging process. A humid environment or packaging materials that are not completely dried will cause the rice to absorb water, resulting in mold, clumping, and reduced quality and taste. Increased moisture content may also breed mold and produce harmful substances such as aflatoxin, threatening food safety. In addition, damp rice is prone to sticking to the packaging equipment, affecting operating efficiency, increasing cleaning costs, and causing economic losses during long-term storage due to its dampness.

[0004] Secondly, rice contains a large amount of dust after hulling and collection, so it cannot be packaged directly and requires dust removal equipment. Dust will affect the color and taste of the rice, making it look dull and impure. After cooking, it may contain impurities or odors, reducing the consumer's eating experience. Dust may contain microorganisms, heavy metals, or other pollutants, and long-term ingestion may harm health. This not only fails to meet food hygiene standards but may also lead to food safety complaints or regulatory penalties. If customer complaints or returns are caused by dust issues, the company will have to bear additional after-sales processing costs, affecting its economic benefits.

[0005] Crucially, rice weevils can infest rice. If not removed before repackaging, weevils' eggs or adults can be mixed into the packaging, leading to pest infestation during storage, reducing the quality of the rice. Insect contamination not only affects the taste but also accelerates mold growth and shortens the shelf life. Furthermore, insect residues may not meet food safety standards, leading to consumer complaints and damaging brand reputation. In the long run, insect problems will increase return rates and economic losses.

[0028] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example

[0030] See appendix Figure 1-5 A rice packaging device includes a shell 1, a discharge pipe 2, a support 3, a partition plate 5, a discharge hopper 6, an insect removal device, a dust removal device, and a drying device. The support 3 is fixedly connected to the shell 1, the discharge pipe 2 is fixedly connected to the shell 1, the partition plate 5 is fixedly connected to the discharge hopper 6, and the partition plate 5 is placed below the discharge pipe 2. The dust removal device includes a fixed base 10, on which a suction motor 11 is connected. The air inlet end and the air outlet end of the suction motor 11 are respectively connected to an air inlet pipe 9 and an exhaust pipe 12. The drying device includes a motor base 13, a fan motor 14, fan blades 15, a fan shell 16, a heating tube 17, and a drying shell 18. The motor base 13 is fixedly connected to the drying shell 18, the fan motor 14 is fixedly connected to the motor base 13, the fan blades 15 are rotatably connected to the fan motor 14, the fan blades 15 are rotatably connected to the fan shell 16, the heating tube 17 is fixedly connected to the drying shell 18, and the drying shell 18 is fixedly connected to the shell 1.

[0031] In this embodiment, the insect removal device includes an insect discharge port 8, a baffle 4, a screen 19, a surrounding plate 20, a connecting plate 21, a connecting shaft 22, a rotary motor 23, and a cam 24. The baffle 4 is fixedly connected inside the housing 1 and is fixedly connected to the insect discharge port 8. The connecting shaft 22 is fixedly connected to the housing 1. The screen 18 is rotatably connected to the connecting shaft 22. The surrounding plate 20 is fixedly connected to the screen 19. The connecting plate 21 is fixedly connected to the screen 19. The connecting plate 21 is in contact with the cam 24. The cam 24 passes through the housing 1 and is rotatably connected to the rotary motor 23. The rotary motor 23 is fixedly connected to the housing 1.

[0032] In this embodiment, the shell 1 is provided with a feeding port 7, the feeding port 7 is provided with a feeding hopper 25, the insect discharge port 8 is provided with a detachable insect discharge plate 29, and the discharge pipe 2 is provided with a valve 28. The feeding hopper 25 and the valve 28 make the feeding and discharging of rice more convenient. After the packaging is completed, the insect discharge plate 29 can be removed to sweep the rice weevils that were sieved out from inside the shell 1 to outside the shell 1.

[0033] In this embodiment, the air intake pipe 9 is equipped with a filter screen 26 to prevent rice from being sucked into the dust removal device and affecting the normal operation of the dust removal device.

[0034] In this embodiment, the housing 1 is provided with a support plate 27. When the rotating motor 23 rotates the protrusion of the cam 24 to the top, the cam 24 contacts the connecting plate 21 and lifts the connecting plate 21. When the protrusion of the cam 24 rotates to the bottom, the cam 24 separates from the connecting plate 21. Under the influence of gravity, the connecting plate 21 falls and is held up by the support plate 27. The screen 19 is rotatably connected to the housing 1 and fixedly connected to the connecting plate 21. The rotation of the protrusion of the cam 24 from top to bottom will cause the screen 19 to vibrate once, causing the rice weevils to be shaken off the mesh of the screen 19, thus completing the insect removal work.

[0035] When the equipment is needed, the rotary motor 23 is started to rotate the cam 24. The cam 24 causes the connecting plate 21 to repeatedly rise and fall. The rise and fall of the connecting plate 21 causes the screen 19 to rotate inside the housing 1 via the connecting shaft 22. The support plate 27 limits the falling position of the connecting plate 21, thus completing the vibration of the screen 19. At the same time, it can prevent the connecting plate 21 from damaging the cam 24 and the rotary motor 23 when it falls. Then, the fan motor 14 and the heating tube 17 on the motor base 13 are started. The fan blades 15 rotate inside the fan housing 16 to blow hot air. The direction of the hot air is fixed by one side of the drying housing 18, thus completing the drying process of the rice.

[0036] When rice needs to be fed into the equipment, it is fed into the feed hopper 25 and enters the shell 1 through the feed inlet 7. The surrounding plate 20 ensures that the rice entering from the feed inlet 7 is concentrated and falls onto the screen 19. The vibration of the screen 19 causes rice weevils to fall from the mesh of the screen 19 onto the baffle 4 and accumulate at the insect discharge port 8. When dust removal is required, the suction motor 11 connected to the shell 1 through the fixed base 10 is turned on. The suction motor 11 sucks out the dust and debris in the shell 1 through the filter screen 26 and the air inlet pipe 9 and discharges it through the exhaust pipe 12, completing the rice dust removal work. When the rice needs to be packaged for the final stage, the valve 28 connected to the discharge pipe 2 is opened. The rice is divided into two parts through the separator plate 5 and discharged from the discharge hopper 6 for packaging. After the packaging is completed, the insect discharge plate 29 is removed from the shell 1 to sweep the rice weevils out of the shell.
