Method for extracting chamomile extract by using countercurrent tube type ultrasonic device

Abstract

The invention provides a method for extracting chamomile extract by using a countercurrent tube type ultrasonic device. The method comprises the following steps: picking fresh chamomile flower petals, drying the petals in shade, smashing and sieving the petals by using a sieve with 10-40 meshes, conveying the sieved petals into a countercurrent tube type ultrasonic extraction machine at the speed of 100 kg/h, reversely conveying organic solvent at the flow rate of 500-1000 L/h, performing extraction at the temperature of 25-55 DEG C for 20-60 min to obtain a mixture of the chamomile flower and the organic solvent, conveying the extraction mixture in a liquid slag separation device to be subjected to squeezing and separation at the speed of 20-100 kg/h to obtain a mixture of the chamomile flower extract and the organic solvent; conveying the mixture into a dynamic circulating low-temperature evaporation concentrator, reducing the pressure to -0.06 MPa, performing concentration, maintaining the temperature of 20-55 DEG C, recycling the organic solvent, and collecting concentrated chamomile flower extract.

AI Technical Summary

Benefits of technology

This patented technique involves combining different techniques for efficiently obtaining valuable substances from plants called chamoms' flowers without damaging them or causing harmful side reactions during processing. It achieves this by creating two types of solutions - one solution uses less expensive materials while another approach concentrating certain compounds more effectively on others. By continuously operating these systems under specific conditions, it allows for efficient collection of useful products such as pharmaceuticals, nutritional supplements, flavors, fragrance oils, etc., resulting in improved productivity rates, reduced waste generation, lower cost per unit weight of processed food compared to conventional processes.

Problems solved by technology

This patented technology describes an improved process called CounterCurrent Ultrasound Extraction (CUWE). It involves crushing or breaking up crude carpels containing certain substances like flavors, oils, acids, bases, amino acid derivatives, sugar molecules, polysaccharide polymer chains, polyphenolics, fats, vitamines, mineral salts, phytochemistry agents, enzyme preparations, antioxidants, antihypertensives, hormones, growth factors, nutrients, medicinal compounds, pesticidal compositions, dyes, fragrance products, food colorings, cosmeceuticals, and others. By continuously applying pressure waves with specific frequencies at different locations within the chamber filled with these materials, they break down into smaller particles without losing their original properties. These small fragments then become absorbed throughout the entire volume inside the container during processing.
