Background The shikonin is used as naphthoquinone natural pigment extracted from root of radix Arnebiae, has various pharmacological activities such as antiinflammatory, antitumor and wound healing promoting, and can be widely used in medicine, cosmetics and food industry fields. Because shikonin is low in content in lithospermum and is sensitive to heat, research on extraction process and equipment thereof has been an important point of industry. The traditional shikonin extraction device mostly adopts a normal pressure soaking or reflux extraction mode, and a conventional extraction tank usually adopts interlayer heating and can be operated in a closed environment, but the design pressure in the tank is lower, so that the intensified extraction under the high pressure condition is difficult to realize. In order to optimize the extraction efficiency, various improvements appear in the prior art, such as an extraction device capable of rapidly extracting shikonin, which is disclosed by publication No. CN108558633A, and comprises a grinder, an ultrasonic cleaner and an extraction tank, and is provided with a temperature controller to realize accurate temperature control, but the structural design is mainly based on conventional extraction equipment, the extraction temperature can be controlled, but the pressure regulation capability is lacking, the requirement on the temperature and pressure cooperative control in shikonin extraction is difficult to be met, the material stacking mode is simple, a solvent is easy to form channeling in the extraction process, the contact of the material and the solvent affects the full dissolution of active ingredients, and a shikonin oil filtering extraction device disclosed by publication No. CN222250646U is detachably provided with a filter screen in the extraction tank, and a heating device is arranged at the inner edge of the extraction tank to accelerate the oil yield, so that the problems of impure extraction and low oil yield of the existing shikonin the prior art are solved. The device is provided with a filter screen for filtering materials, but the filter structure is of a fixed design, the surface of the filter screen is easy to be covered and blocked by medicine residues in the long-time extraction process, shutdown and disassembly are needed during cleaning, so that the production efficiency is seriously affected, meanwhile, the heating mode of the device is an integral heating mode, the materials at different layers cannot be differentially controlled in temperature according to the extraction process, and multiple requirements of cell wall breaking, solubilization and dissolution and thermal degradation prevention are difficult to be met. In the comprehensive view, the existing shikonin extracting device mainly adopts a single cavity structure, a material stacking mode is simple, solvent is easy to form channeling in the extracting process, so that the material is not uniformly contacted with the solvent, particularly, the shikonin extracting device is difficult to realize rapid wall breaking of internal cell structures for the medicinal materials with harder textures such as shikonin, and is mainly heated by an integral jacket or a single electric heating element during extracting, differential temperature control cannot be carried out on the materials in different extracting stages according to the extracting process, and researches show that shikonin extracting is sensitive to temperature, and multiple requirements of cell wall breaking, solubilization and dissolution and thermal degradation prevention are difficult to be met by single temperature.
