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.

preparation approach 1

[0019] Take 100kg of chamomile flowers that have been crushed through a 20-mesh sieve, and input them into a continuous countercurrent tubular ultrasonic extractor that meets the national standard of JB / T20126-2009 at a speed of 100kg / h, and input them into Xinjiang Jiepule Biotechnology Co., Ltd. at a flow rate of 800L / h. The produced organic solvent ethanol (95%) was extracted for 45 minutes while maintaining the temperature of the ultrasonic extraction tube at 40°C to obtain the chamomile ethanol mixture; after the mixture was input into the extraction liquid residue squeezing separation device, the residue material and the extraction mixture were separated; The extracted mixture is input into a dynamic circulating low-temperature and reduced-pressure (-0.06MPa) evaporation concentrator, and the temperature is maintained at 45°C. The organic solvent ethanol is evaporated and recovered for reuse. Collect 12 kg of the remaining extract, which is the chamomile flower extract, wi...

[0021] Take 100kg of chamomile flowers that have been crushed through a 20-mesh sieve, and input at a speed of 100kg / h into a continuous countercurrent tubular ultrasonic extractor that meets the national standard of JB / T20126-2009, and input the reverse flow rate of 1000L / h into Tianjin Fuyu Fine Chemical Co., Ltd. The organic solvent ethyl acetate is extracted for 40 minutes at a temperature of 45°C in the ultrasonic extraction tube to obtain the ethyl acetate mixture of chamomile flowers; after the mixture is fed into the extraction liquid residue squeezing separation device, the residue and the extraction mixture are separated; the extraction mixture Enter the dynamic cycle low-temperature decompression (-0.06MPa) evaporation concentrator, keep the temperature at 40℃, evaporate and reuse the organic solvent ethyl acetate, collect the remaining extract 10kg, which is the chamomile flower extract, the yield is 10%.

example 1

[0024] The addition of chamomile handmade soap:

[0025] In the production of handmade soap, after the saponification reaction process is completed, add 0.5-3% of chamomile extract (kg / kg) when the temperature of the saponification solution is maintained at 40-80℃, and stir it evenly at constant temperature and inject it into a molding mold to cool, divide, and package chamomile hand-made soap. The chamomile extract is used in the production of handmade soaps, instead of the use of chemical flavors and pigments in ordinary soaps. After use, the body surface can retain fragrance continuously, which can play a role in whitening, moisturizing, moisturizing, antibacterial, anti-allergic, etc. .

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.
