Description

Technical Field

[0001] The present application relates to the technical field of lutein production, and in particular to an impregnation device for lutein extraction. Background Art

[0002] The existing lutein extraction process uses marigold petals as raw materials, and obtains lutein crystals through extraction, saponification, crystallization, recrystallization, vacuum distillation, filtration, and drying process steps (CN 200710156573.3 discloses high-purity lutein crystals prepared from marigold petals and a production method thereof). The extraction process is to mix marigold petals with an extraction solvent, soak them, and then reduce the pressure to concentrate them to obtain a concentrate for subsequent operations.

[0003] The petals need to be immersed in the extraction process to improve the extraction efficiency. The main equipment of the existing immersion equipment is a pressure vessel extraction tank, in which an organic solvent is added as a carrier, and the organic solvent is immersed in the marigold petals in the pressure vessel extraction tank to extract the effective substances of the material.

[0004] The organic solvent flows into the pressure vessel extraction tank through the solvent collection pipe. One end of the existing solvent collection pipe is blocked and the other end is connected to the pressure vessel extraction tank. Three branch pipes are arranged on the collection pipe at intervals and connected to each branch pipe. When the liquid is discharged, the material in the branch pipe impacts the wall of the collection pipe away from each branch pipe, causing solvent impact wear and solvent corrosion. After long-term use, the thickness of the pipe wall on one side of the collection pipe is reduced, and there is a risk of leakage, which brings serious safety hazards to production.

[0005] Once the manifold leaks, the entire workshop must be shut down, which seriously affects production continuity and output. When the manifold needs to be repaired, all the equipment in the workshop must be dissolved for repair and replacement, which is cumbersome and costly, delaying normal production. Once the manifold leaks, in order to ensure normal production, on-site construction can only be carried out in the workshop, but due to the production site environment, construction is difficult to carry out, which also increases the safety risks of production.

[0006] The information disclosed in the background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in the field.
