Description

Technical Field

[0001] This utility model belongs to the field of fragrance processing, specifically involving a multi-stage grinding and refining device for fragrances. Background Technology

[0002] A spice grinding and refining device is a piece of equipment used to crush, grind, and refine spice raw materials. This device is commonly used in food processing, condiment production, and spice extraction industries. It grinds spice particles into finer particles, which can better release aroma and flavor, or facilitate mixing and subsequent processing.

[0003] Existing spice grinding and refining devices typically consist of a grinding block and a grinding base. During use, the grinding block is rotated by an electric motor to grind and refine the spices. When a large amount of spices needs to be ground, the gap between the grinding block and the grinding base may allow some spices to enter the finished product without being ground. Furthermore, the unground spices mixed into the finished product are difficult to remove, which may affect the quality of the ground product.

[0004] Therefore, to address the issue that the aforementioned powder refining device may allow a small portion of powders that do not meet particle size requirements to enter the finished product pile, a multi-stage powder refining device has been developed. This device utilizes a multi-stage grinding structure consisting of a grinding cylinder and a grinding jar. After the initial grinding of the powders, a fine grinding block performs a secondary grinding, increasing the number of grinding steps and reducing the probability of substandard powders mixing into the finished product. Furthermore, a movable screen structure consisting of a funnel and a sieve can block powders that do not meet the requirements, and the sieve can be removed for re-grinding, further improving the quality of the finished product. Utility Model Content

The fine grinding block 18 is adapted to the fine grinding seat 17. A funnel 3 is threadedly installed at the lower end of the grinding jar 2. A screen 5 is installed inside the funnel 3.

[0026] The output of the first motor 10 can drive the coarse grinding block 12 to rotate, and perform initial grinding on the spices that fall between the coarse grinding block 12 and the coarse grinding seat 8. The output of the second motor 13 can drive the fine grinding block 18 to refine the spices after the initial grinding, thus improving the grinding process. The ground spices can then be sieved through the screen 5. The funnel 3, which is threaded onto the lower end of the grinding tank 2, can be easily disassembled, allowing the screen 5 to be removed and the unqualified spices to be poured into the grinding cylinder 1 for re-grinding.

[0027] Please see Figures 2-3 In this embodiment, a feed pipe 7 is installed on the outer wall of the grinding cylinder 1. One end of the feed pipe 7 is located outside the grinding cylinder 1, and the other end of the feed pipe 7 corresponds one-to-one with the upper opening of the coarse grinding seat 8.

The first motor 10 is started, and the output end of the first motor 10 rotates to drive the coarse grinding block 12 to perform the initial grinding of the spices. After the initial grinding, the spices fall into the fine grinding seat 17. Then, the second motor 13 is started, and the output end of the second motor 13 rotates to drive the fine grinding block 18 to perform the fine grinding of the spices after the initial grinding. After the grinding is completed, the spices fall into the sieve 5. The vibration of the motor accelerates the sieving of the spices by the sieve 5. After the sieving is completed, the spices are collected by the funnel 3 and fall into the container. Finally, the first motor 10 and the second motor 13 are turned off, the container is removed, and the funnel 3 is manually unscrewed to recover the unqualified spices.

[0031] Through the above steps, the output of the first motor 10 can drive the coarse grinding block 12 to perform initial grinding of the spices that fall between the coarse grinding block 12 and the coarse grinding seat 8. The output of the second motor 13 can drive the fine grinding block 18 to perform fine grinding of the spices after the initial grinding. The screen 5 can screen the ground spices, which solves the problem that a small part of the spices that do not meet the particle size requirements may enter the finished product pile when the spice grinding and refining device is used.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
