摘要:
Active pharmaceutical ingredients can be separated from their excipients by dissolving a pharmaceutical product (e.g. tablet, pill) into a solvent, then running the solution through an acoustophoretic device. Standing waves are used to separate the excipient from the active ingredient dissolved in the solvent.

A method of extracting recovering oil from vegetable material in which oil bearing material is heated and subjected to sonication at least one frequency above 400 kHz, removing a first yield of oil by decanting and subjecting the retained material to centrifugal separation to separate out a second yield of oil. Preferably the raw vegetable material is passed through a screw press and the obtained material is heated and subjected to the ultrasonic treatment and then allowed to settle for a predetermined period before decanting the oil layer. Preferably two frequencies above 400 kHz are used, one below 1 MHz and the second from 1 MHz. There are many potential transducers arrangements possible for producing standing waves.

The present invention provides an extraction method that either does not use emulsifiers, organic solvents, and the like or can reduce the amount used of emulsifiers, organic solvents, and the like. In addition, the extraction method of present invention can also efficiently extract various components from various materials to be extracted, and can highly maintain potency and the like of the extracted components, in particular if the components are active agents. Furthermore, the extraction method of present invention has excellent safety. The extraction method of present invention is achieved by bringing materials to be extracted into contact with liquid containing ultra fine bubbles for extraction treatment. The ultra fine bubbles utilized during the extraction process preferably have a mode diameter of 500 nm or smaller and a concentration of 1,000,000 or more per 1 ml of liquid.

There is provided a process for producing fine particles of an organic compound by a continuous-type poor solvent precipitation method which is capable of rapidly and uniformly dispersing an organic compound-containing solution in a large amount of a poor solvent, thereby more readily producing fine particles of the organic compound having a volume-average particle size of not more than 1 μm. In the process for producing fine particles of an organic compound, the poor solvent in which the organic compound is hardly soluble, is continuously mixed with the organic compound-containing solution prepared by dissolving the organic compound in a good solvent which is miscible with the poor solvent and in which the organic compound is readily soluble, while irradiating an ultrasonic wave thereto.
摘要:
In order to dislodge our bubbles from particles e.g. cut cylindrical fibers, as they enter a confined liquid body through a surface, a small portion of the liquid body near the surface is vibrated and the particles are funneled into the liquid body through the surface by means calculated to subject each particle to about the same amount of vibration. By preference this includes funneling the particles onto the central region of a submerged, perforated plate. The particles vibrate to the periphery of the plate and fall into the gap between the plate and the confining walls of the liquid body. In a counter current liquid extraction system, liquid may pass up through the plate perforations.

A plant oil extraction system may include a reservoir tank, an agitator tank, a boiler tank, a condenser unit, and a vacuum chamber. The reservoir tank may hold a solvent to be used in the system process. The solvent may be deposited into the reservoir tank through a fill port. A pump may transfers the solvent from the reservoir tank to the agitator tank. The agitator tank may hold dry plant matter. The agitator tank may separate oil from the plant matter by use of solvent where the mixture of solvent and plant oil drains to the boiler tank. The boiler tank comprise of a tank stack (condenser) used for separating extracted plant oil from the solvent by boiling off the solvent and a vacuum chamber used to extract residual solvent from the oil.

Described herein are systems, methods and embodiments associated with the use of biomass for generating a preparation that can be used in manufacture of a personal care product. The described embodiments include collection of evidence of toxic cyanobacteria presence within biomass. Upon identification of biomass containing toxic cyanobacteria, embodiments describe processing of the biomass which will ultimately lead to the preparation. Thereafter, regardless of the initial presence of toxins, once the biomass is processed, the preparation can be safely used within a personal care product.

Provided is a novel method for extracting nutrients, toxins and drugs from a solid sample, comprising adding a solvent such as hexane and isopropanol to said sample, subjecting the sample and solvent to ultrasonic energy, subjecting the sample and solvent to heat, then removing the solvent liquid fraction from what remains of the sample.Also provided is an apparatus for performing said method in an automated manner.
摘要:
The present invention describes a method and apparatus for aqueous extraction of chemical compounds from solid material in which the solid material is entrained in an extraction liquid phase that flowed around immersed sonotrodes emitting radial or focused high energy ultrasonic waves. A significant increase in extracted material and decreases in extraction time is observed.
