Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a stirring device for preparing blueberry lutein ester compressed candy. Background Technology

[0002] The production of blueberry lutein ester compressed candy requires mixing and stirring of raw materials. Existing mixing devices have several shortcomings. Materials tend to adhere to the inner wall of the mixing vessel during mixing, leading to material waste and affecting product yield; some raw materials may clump during feeding, directly entering the mixing vessel and affecting mixing uniformity; traditional mixing devices are inconvenient to clean and maintain, with scrapers and other components difficult to disassemble, affecting cleaning efficiency; the equipment's transmission structure is sometimes complex, and multiple power sources increase the probability of failure and maintenance costs; these factors all affect production efficiency and product quality and require improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of cleaning and maintenance of traditional stirring devices, the difficulty in disassembling components such as scrapers, and the impact on cleaning efficiency. Therefore, this invention proposes a stirring device for preparing blueberry lutein ester compressed candy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stirring device for preparing blueberry lutein ester compressed candy includes a container stirring vessel for holding raw materials for preparing blueberry lutein ester compressed candy. The top of the stirring vessel is equipped with a top cover. An inspection cover that seals the stirring vessel with the top cover is hinged to the outside of the stirring vessel. A power compartment and a feeding channel are fixed to the top of the top cover by welding.

[0006] A drive motor is fixed to the top of the power compartment by bolts, and a stirring shaft extending into the interior of the mixing vessel is fixed to the bottom of the output shaft of the drive motor.

[0007] A detachable sidewall cleaning mechanism is fixed on the stirring shaft and is used to follow the rotation of the stirring shaft to scrape off the residue on the sidewall of the mixing vessel to improve utilization.

[0008] In one possible design, a spiral stirring rod for stirring is fixed to the outside of the stirring shaft by a fixing sleeve and bolts. The detachable sidewall cleaning mechanism includes an L-shaped scraper that can be removed and installed from the inspection cover position and is detachably mounted on the outside of the stirring shaft. A tough plate with a certain deformation capacity is fixed at the end of the scraper where it contacts the sidewall of the mixing vessel.

[0009] In one possible design, two longitudinally arranged supports are fixed to the outer side of the stirring shaft by welding. The lower support and the bottom of the scraper can be disengaged and engaged by a slot, while the upper support and the scraper can be detached and installed by bolts and bolt holes.

[0010] In one possible design, the stirring shaft is fixedly mounted with a drive bevel gear on the outside of the power compartment. A shearing shaft for dispersing and pre-shearing the raw materials in the feed channel is rotatably mounted on the outside of the power compartment via a bearing. A driven bevel gear that meshes with the drive bevel gear is fixedly sleeved on the shearing shaft in the power compartment.

[0011] In one possible design, the shearing shaft is fixed with a plurality of protruding saw teeth arranged in a ring on the outer side of the feed channel to disperse and shear the lumpy material, and the shearing shaft and the feed channel are rotatably connected by bearings.

[0012] In one possible design, the bottom of the mixing vessel is sealed and connected to a discharge channel, and the outside of the power compartment is provided with a maintenance port to facilitate the later inspection and maintenance of the internal components of the power compartment.

[0013] In this application, when the stirring device is in operation, the drive motor starts and drives the stirring shaft to rotate at a certain speed. The spiral stirring rod installed on the stirring shaft rotates accordingly, thoroughly mixing the raw materials such as blueberry lutein ester, sugar powder, and auxiliary materials in the mixing vessel. The rotational motion of the spiral stirring rod generates axial and radial material flow, causing the materials to form a complex movement trajectory within the vessel, thereby achieving uniform mixing.

[0014] Meanwhile, the rotation of the stirring shaft transmits power to the shearing shaft through the meshing of the driving and driven bevel gears. The shearing shaft rotates at a high speed within the feed channel. When the raw material is added from the feed channel, the rotating serrated teeth exert a shearing and impact effect on the material, effectively breaking up any lumps or agglomerates that may exist in the raw material, thus providing preliminary dispersion treatment before the material enters the mixing tank.

[0015] During the mixing process, the scraper rotates together with the mixing shaft. Because the scraper is fixed to the mixing shaft by a support, positioned by a slot at the bottom and secured by bolts at the top, its stability during rotation is ensured. The flexible plate at the end of the scraper moves closely against the inner wall of the mixing vessel under centrifugal force, continuously scraping off the material adhering to the inner wall and returning it to the mixing zone to participate in the mixing process. The flexible plate is made of a material with a certain degree of elasticity, effectively removing residual material without causing wear to the inner wall of the equipment.

[0016] Once the materials are mixed, stop the drive motor. Open the discharge valve at the bottom of the mixing tank, and the evenly mixed material will automatically flow out under gravity. The smooth design and appropriate angle of the discharge channel ensure that the material is completely discharged, reducing residue.

[0017] During routine maintenance, operators can open the inspection cover, remove the fixing bolts above the scraper, and take the scraper out of the slot below for thorough cleaning or replacement. The maintenance port on the outside of the power compartment allows for easy inspection, lubrication, or replacement of the internal drive and driven bevel gears. The feed channel can also be disassembled and cleaned separately to ensure no residual material affects future use.

[0018] Throughout the entire operation, all parts in contact with materials are made of food-grade materials, ensuring product hygiene and safety. Reliable sealing structures are used between all moving parts to prevent contaminants such as lubricating oil from entering the material area. This device achieves an organic combination of stirring, shearing, and cleaning functions through mechanical transmission, improving production efficiency and raw material utilization.

[0019] In terms of improving mixing efficiency, the spiral stirring rod can create a combined axial and radial flow, ensuring thorough mixing of materials within the vessel. The shearing shaft in the feed channel pre-treats the raw materials through high-speed rotating serrated edges, effectively breaking up material agglomerations and resulting in more uniform and thorough subsequent mixing.

[0020] The detachable sidewall cleaning mechanism plays a crucial role in reducing raw material waste. As the scraper rotates with the stirring shaft, the flexible plate at its end continuously scrapes the inner wall of the vessel, causing raw materials adhering to the wall surface to re-participate in the mixing process. This design significantly reduces material residue and improves raw material utilization.

[0021] In terms of equipment maintenance, the inclusion of inspection covers and maintenance ports provides convenience. Opening the inspection cover allows for quick disassembly and cleaning of the scraper assembly, while the maintenance ports facilitate the inspection and maintenance of gear transmission components. This design reduces maintenance difficulty and time costs.

[0022] In terms of hygiene and safety, all parts that come into contact with materials are made of 304 or 316 stainless steel, the scraper end is made of food-grade nylon, and the bearings are made of food-grade polytetrafluoroethylene. These material choices ensure that the entire production process meets food safety requirements.

[0023] In terms of functional integration, a single motor can simultaneously drive both stirring and shearing functions through bevel gear transmission, simplifying the transmission structure and improving equipment reliability. This design ensures both the completeness of equipment functions and controls manufacturing costs.

[0024] In terms of ease of operation, the discharge channel is controlled by a butterfly valve, which is convenient to open and close; the scraper is fixed by a combination of slots and bolts, which not only ensures stability during operation but also facilitates disassembly and cleaning. These designs make the equipment easier and faster to operate. Attached Figure Description
