Description

Technical Field

[0001] This utility model relates to the field of astaxanthin extraction technology, specifically to a device for extracting high-purity astaxanthin from green algae. Background Technology

[0002] Astaxanthin, also known as astaxanthin or astaxanthin flavonoid, was first extracted in 1933 from shrimp, crab, and other aquatic products as a purplish-red crystalline substance. It was later identified as a carotenoid closely related to astaxanthin, hence the name astaxanthin. It is widely found in shrimp, crab, fish, birds, certain algae, and fungi, and is often referred to as "super vitamin E." Astaxanthin's antioxidant properties, coloring properties, and immune-boosting effects are widely recognized. As a natural food additive, it has broad development prospects. Astaxanthin is produced through both natural extraction and chemical synthesis. Chemically synthesized astaxanthin differs significantly from natural astaxanthin in structure, function, application, and safety. Its stability, antioxidant activity, and coloring properties are also significantly lower than those of natural astaxanthin. Therefore, large-scale production generally favors the extraction of natural astaxanthin.

[0003] For example, an astaxanthin extraction device from Haematococcus pluvialis, as disclosed in announcement number CN221964708U, includes an extraction device body. An inlet is fixedly mounted on the top of the extraction device body, and an outlet is fixedly mounted on the bottom. A motor is fixedly connected to the top of the extraction device body, and a controller is fixedly mounted on one side of the extraction device body. A placement groove is opened at one end of the extraction device body. When Haematococcus pluvialis is broken down and flows into the inner wall of the extraction device body, the Haematococcus pluvialis in the mucus is filtered through a filter plate, and astaxanthin is extracted from the mucus of the Haematococcus pluvialis. Simultaneously, by opening the buckle, the rotating plate can be rotated, and a tension belt allows the filter plate to be pulled out from the inner wall of the scraping plate, achieving rapid filter plate replacement and solving the problem of slow filtration caused by filter plate clogging.

[0004] The aforementioned patent enables rapid replacement of the filter plate. However, in actual use, due to the prolonged use of green algae for astaxanthin extraction, the inside of the device needs to be cleaned after a period of use. The device has poor cleaning effect on the inner wall during actual use, and it is inconvenient to disassemble and clean.

[0005] Therefore, we propose a high-purity astaxanthin extraction device from green algae to solve the problems mentioned above. Utility Model Content
