Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a raw material grinder for processing L-carnitine coffee powder. Background Technology

[0002] L-carnitine coffee powder is a health drink that combines L-carnitine and coffee. This drink is usually designed to provide the energizing effect of caffeine and the benefits of L-carnitine, which may help increase metabolism and fat burning. In the processing, grinding coffee beans is a very critical step in the production process, which directly affects the taste and quality of the final product.

[0003] Patent CN212346290U discloses a coffee grinder. This patent uses a rotating stirring tooth and a guide plate to facilitate the entry of coffee beans between the upper and lower blades, preventing clogging at the feed inlet. Furthermore, when grinding harder, larger coffee beans, the rotating stirring tooth and guide plate can initially break them down before feeding them between the upper and lower grinding blades for fine grinding. This design reduces the grinding intensity of the upper and lower grinding blades, increasing their lifespan. However, this patent still has some shortcomings in practical applications. The single grinding chamber design, while meeting basic grinding needs, limits the amount of coffee beans that can be processed at one time, making it difficult to adapt to the needs of large-scale production and continuous processing. Additionally, when dealing with coffee beans of varying sizes and hardness within the same batch, a single grinding parameter cannot accommodate all situations, potentially leading to over-grinding of some beans while under-grinding others, affecting the quality and taste of the final product.

[0004] Therefore, a raw material grinder with a dual grinding chamber design for processing L-carnitine coffee powder is developed to improve production efficiency and product quality. Utility Model Content

[0005] In order to overcome the shortcomings of existing single-grinding chamber designs, such as limited production capacity and uneven grinding when processing large quantities of coffee beans, this utility model provides a raw material grinder for processing L-carnitine coffee powder with a dual-grinding chamber design.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a raw material grinder for processing L-carnitine coffee powder, comprising a base, on which symmetrically distributed grinding chambers are arranged. Each grinding chamber has a fixed support ring inside, and each support ring has several guide rods slidably arranged on it. The guide rods collectively house a filter cylinder. A servo motor is mounted on the upper end of each grinding chamber, and a rhomboid rod is connected to the output shaft of the servo motor. A rotating rod is connected to the rhomboid rod via a key, and multiple grinding heads are mounted on the rotating rod. The grinding chambers are collectively connected to a connecting pipe, and the bottom end of the connecting pipe is connected to and communicates with a collection frame located in the lower part of the base.

[0007] To further explain, the lower part of the grinding chamber is tapered.

[0008] To further explain, each of the grinding chambers is equipped with a motor on its outer side, and a transmission gear is connected to the output shaft of the motor. Each filter cartridge is fitted with a gear ring that meshes with the transmission gear. A scraper is slidably mounted on the gear ring. The upper end of the scraper is in close contact with the surface of the filter cartridge, and the lower end is in contact with the inner wall of the conical area of ​​the grinding chamber.

[0009] To further explain, a convex ring is fixedly connected to the top of the scraper rod, and a contact ring that engages with the convex ring is provided at the top of the filter cylinder. The surfaces of the convex ring and the contact ring are designed with an inclined plane and the inclined plane has a certain angle. A return spring is sleeved on the guide rod, and the two ends of the return spring are respectively connected to the support ring and the filter cylinder.

[0010] To further explain, each of the grinding chambers is equipped with a material collection hopper at the top.

[0011] To further explain, each of the grinding chambers is provided with a protective shell on its outer side, and the motor is located inside the protective shell.

[0012] To further explain, the side of the base that contacts the ground is provided with an anti-slip pad.

[0013] Compared with the prior art, the present invention has the following technical effects: 1. By setting up two independently operating grinding chambers, the device can process more coffee beans at the same time, which significantly improves the output per unit time. It is particularly suitable for large-scale production environments. Moreover, each grinding chamber is equipped with an independent grinding device, which can automatically adjust the grinding parameters according to the characteristics of coffee beans, ensuring that the coffee beans are subjected to uniform shear force and friction during the grinding process, thereby obtaining consistent fineness and improving the quality of the final product.

[0014] 2. The motor drives the transmission gear to rotate, which in turn drives the toothed ring outside the filter cartridge to rotate. The scraper rotates along the surface of the filter cartridge and the inner wall of the conical area of ​​the grinding chamber, which can effectively scrape off the attached coffee powder, prevent clogging and clumping, and ensure that the powder flows smoothly through the connecting tube into the collection box.

[0015] 3. The interaction between the return spring and the convex ring and the contact ring enables the filter cartridge to vibrate up and down, increasing the friction between the filter cartridge and the grinding head. This helps to grind the coffee beans more thoroughly, improving the grinding effect. At the same time, it makes the coffee beans more evenly distributed in the filter cartridge, avoiding local over-dense or over-sparse areas, ensuring that each coffee bean is evenly ground during the grinding process, thus improving the consistency and quality of grinding.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0024] Example 1: Please refer to Figures 1-4A raw material grinder for processing L-carnitine coffee powder includes a base 1. An anti-slip pad 21 is provided on the side of the base 1 that contacts the ground. The anti-slip pad 21 increases the friction between the base 1 and the ground, preventing the equipment from sliding or tilting during operation and ensuring the stability and safety of the equipment. The base 1 is provided with symmetrically distributed grinding chambers 2, achieving a dual grinding chamber design. Each grinding chamber 2 has a collection hopper 19 at its top, which effectively concentrates the added coffee beans into a filter cartridge 3. A support ring 4 is fixedly installed at the upper part of each grinding chamber 2. Six guide rods 5 are slidably installed on each support ring 4. Six adjacent guide rods 5 are connected together to form a filter cartridge 3. A servo motor 6 is installed at the upper end of the grinding chamber 2. The servo motor 6 can precisely adjust the rotation speed according to the size, hardness and required fineness of the coffee beans to ensure the efficiency and uniformity of the grinding process. A diamond-shaped rod 7 is connected to the output shaft of the servo motor 6. A rotating rod 8 is connected to the diamond-shaped rod 7 by a key. Three grinding heads 9 are mounted on the rotating rod 8. The grinding heads 9 contact the inner wall of the filter cylinder 3 and grind the coffee beans through friction. The lower part of each grinding chamber 2 is conical and is connected to a connecting pipe 10. The bottom end of the connecting pipe 10 is connected to and communicates with a collection frame 11 set in the lower part of the base 1 for placing a container for collecting coffee powder. The conical design helps guide the powder through the connecting pipe 10 into the collection frame 11.

[0025] First, the container for collecting coffee powder is placed into the collection frame 11. Then, coffee beans of different sizes and hardness are added to the two grinding chambers 2. Under the action of the internal collection hopper 19, the coffee beans are concentrated and guided into the filter cartridge 3. Subsequently, according to the characteristics of the added coffee beans, the speed of the two servo motors 6 is adjusted to control the grinding fineness of the coffee powder by the two grinding heads 9, ensuring that the final product quality meets the requirements. Next, the two servo motors 6 are turned on, and their output shafts drive the diamond-shaped rod 7 to rotate. The rotation of the diamond-shaped rod 7 is transmitted to the rotating rod 8 through a key connection, causing the rotating rod 8 and the grinding head 9 on it to rotate accordingly. As the rotating rod 8 rotates... The grinding head 9 and the inner wall of the filter cylinder 3 move relative to each other, generating shearing and frictional forces. These forces act on the coffee beans, gradually grinding them into fine particles. During the continuous grinding process, coffee powder that reaches a certain fineness will fall into the cone-shaped area below through the holes of the filter cylinder 3, and then be collected in the collection frame 11 through the connecting pipe 10. Larger particles that do not reach the required fineness will remain in the filter cylinder 3 for further grinding. When the two grinding chambers 2 have completed the required grinding time, the servo motor 6 is turned off to stop the grinding process. At this time, the container can be taken out, and the collected coffee powder inside can be taken out for further processing or packaging.

[0026] Example 2: Based on Example 1, please refer to... Figure 5and Figure 6 Each of the grinding chambers 2 has a motor 12 installed on its outer side. A transmission gear 13 is connected to the output shaft of the motor 12. Each of the filter cylinders 3 is fitted with a gear ring 14 that meshes with the transmission gear 13. A scraper 15 is slidably installed on the gear ring 14. The upper end of the scraper 15 is in close contact with the surface of the filter cylinder 3, and the lower end is in contact with the inner wall of the conical area of ​​the grinding chamber 2. Each of the grinding chambers 2 has a protective shell 20 installed on its outer side. The motor 12 is located inside the protective shell 20. The protective shell 20 can effectively protect the motor 12 from the intrusion of external dust, moisture and other impurities, and extend the service life of the motor 12.

[0027] Once the coffee powder is ground, the motor 12 is turned on, and the motor 12 starts running. Its output shaft drives the transmission gear 13 to rotate. The transmission gear 13 meshes with the gear ring 14 on the outside of the filter cartridge 3. When the transmission gear 13 rotates, the gear ring 14 also rotates. As the gear ring 14 rotates, the scraper 15 rotates along the surface of the filter cartridge 3 and the inner wall of the conical area of ​​the grinding chamber 2. At this time, the upper and lower ends of the scraper 15 scrape off the coffee powder adhering to the surface of the filter cartridge 3 and the inner wall of the conical area of ​​the grinding chamber 2, thereby cleaning the filter cartridge 3 and preventing clogging and clumping. At the same time, it removes the coffee powder adhering to the inner wall of the conical area of ​​the grinding chamber 2, ensuring that the powder flows smoothly through the connecting pipe 10 into the collection frame 11.

[0028] Please see Figure 5 and Figure 6 The scraper 15 has a convex ring 16 fixedly connected to its top end. The filter cylinder 3 has a contact ring 17 that contacts and engages with the convex ring 16 at its top end. The surfaces of the convex ring 16 and the contact ring 17 are designed with bevels and the bevels have a certain angle to ensure that the convex ring 16 can smoothly disengage and squeeze the contact ring 17 when it rotates. The guide rod 5 is fitted with a return spring 18. The two ends of the return spring 18 are respectively connected to the support ring 4 and the filter cylinder 3 to provide a restoring force for the filter cylinder 3.

[0029] In the initial state, the filter cylinder 3 is held in a predetermined position by the elastic force of the return spring 18. At the same time, the convex ring 16 is engaged with the inclined surface on the contact ring 17. When the scraper 15 rotates, the convex ring 16 at the top of the scraper 15 also rotates. The rotation of the convex ring 16 displaces the inclined surface on the contact ring 17, causing the convex ring 16 to press against the contact ring 17. This causes the contact ring 17 to move the filter cylinder 3 downward. During this process, the return spring 18 is compressed and stores elastic potential energy. When the convex ring 16 rotates to its original position, the inclined surface re-engages. At this time, the return spring 18 releases its stored elastic potential energy, pushing the filter cylinder 3 to return to its original position. This process is repeated, creating an up-and-down vibration effect of the filter cylinder 3. The vibration increases the friction between the filter cylinder 3 and the grinding head 9, which helps to grind the coffee beans more thoroughly and improve the grinding effect. At the same time, it makes the coffee beans more evenly distributed in the filter cylinder 3, improving the consistency and quality of grinding.

[0030] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
