Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, and in particular to a cork resin extraction device. Background Technology

[0002] Cork resin, an important component of cork, has shown broad application potential in various fields such as food packaging, building insulation materials, and cosmetic raw materials. With the increasing demand for cork resin from related industries, developing efficient and reliable cork resin extraction equipment has become crucial.

[0003] Traditional cork resin extraction methods have many limitations. Early extraction processes often used simple soaking or intermittent stirring extraction, which is inefficient, requires large amounts of solvent, and has a long extraction time. For example, some small-scale workshops simply place the cork raw material in a solvent and let it soak for a long time. This not only results in a low cork resin extraction rate but also extremely low solvent utilization, leading to resource waste and increased costs.

[0004] With the development of industrial technology, some improved extraction devices have emerged. However, these devices still face many problems in actual operation. Ensuring sufficient contact and recycling of the solvent with the cork raw material during extraction remains a technical challenge. While some devices have circulation systems, the lack of effective filtration and anti-clogging mechanisms easily leads to pipe blockages or filter failure. Once the filter is clogged by solid impurities such as cork residue, the circulation of the solvent is hindered, causing the extraction process to be interrupted or its efficiency to drop sharply. This not only affects the continuity of production but also increases the frequency and cost of equipment maintenance. Utility Model Content
