Description

Technical Field

[0001] The invention belongs to the field of agricultural product processing equipment, and particularly relates to a bergamot flavonoids extraction device for preparing wine. Background Art

[0002] Flavonoid compounds have a variety of important physiological activities and medicinal values, and have broad application prospects in the fields of food and medicine. In the process of flavonoid extraction, alcohol is often used as an extraction solvent. Experimental studies have shown that the higher the alcohol content, the higher the flavonoid extraction rate ( Fig. 9 ). As a plant resource rich in flavonoids, bergamot has great development potential. The bergamot "prepared wine" developed from flavonoids extracted from bergamot has been widely welcomed in the market in recent years. Therefore, efficient bergamot flavonoid extraction equipment and technology are particularly necessary. However, bergamot coarse powder or fresh bergamot slurry contains a certain amount of water. During the extraction process, part of the water will dissolve in the alcohol, thereby reducing the concentration of alcohol and resulting in a lower extraction rate of flavonoids. This poses a challenge to the efficient extraction of bergamot flavonoids. At present, the existing flavonoid extraction methods are often difficult to effectively solve the problem of the influence of water on the extraction rate when applied to bergamot flavonoid extraction. Traditional extraction equipment cannot control the moisture content in the extraction process well, and cannot guarantee a high extraction rate of flavonoids. In addition, bergamot contains limonin, which will be extracted together during the alcohol extraction of flavonoids, and bergamot flavonoids containing a large amount of limonin will have a heavier bitter taste when used in preparatory wine, thereby affecting the taste of the wine. Therefore, the content of limonin needs to be reduced as much as possible during the extraction process.

[0003] In order to make full use of the flavonoid resources in bergamot, meet the market demand for high-purity and high-extraction rate flavonoids, and reduce the bitterness of bergamot flavonoid liquor, an innovative method or equipment is urgently needed to extract flavonoids in bergamot, ensure the extraction rate of flavonoids, and reduce the content of limonin in flavonoids.

In this application, an extraction bin and a filter element are designed. The inner side of the inner wall is used to place the substance to be extracted, and a row plate is provided on the outer side of the filter element. During the rotation of the filter element, the bergamot residue can be discharged outward, effectively preventing the residue from clogging the filter cotton. A reflux hole is provided on the inner wall, and two streams of water can continuously stir the residue. At the same time, a reverse shear rod is provided on the inner wall, and a tangent rod is provided on the row plate.

The filter element pushes the rubber ring against the lower part of the bin cover. After the circulation part is turned on, water flows out from the lower part of the circulation part, and the solution enters the inner side from the outer side of the inner wall. Under the joint action of the solution and pressure, the filter element is further urged to be close to the lower part of the bin cover, thereby ensuring that the water flow ejected from the outer filter hole has a certain pressure, making the stirring more sufficient. 3. Based on the characteristics of the above-mentioned technical effects 1 and 2, the filter element is divided into inner and outer tubes, and water-absorbing silica gel is placed on the outside. During the solution circulation process, the silica gel particles can absorb the moisture absorbed by the alcohol from the debris, ensuring a high concentration of alcohol, and thus making the flavonoids in the bergamot debris have a high extraction rate; diatomaceous earth ceramsite has a small adsorption capacity for flavonoids, but a strong adsorption capacity for limonin, which can reduce the content of limonin in the flavonoid extract, and the bitterness of the flavonoids will be reduced after the flavonoids are used in the drinking wine; therefore, the scheme of the present application can effectively improve the taste of bergamot flavonoid wine.
