Abstract

The invention discloses a microwave-assisted extraction device which is characterized in that the device comprises a distillation extraction container and an oil-water separation device, a container cover is arranged at the top of the distillation extraction container, a concave flow guide collector is arranged at the upper part of the distillation extraction container, a liquid collector is arranged below the concave flow guide collector, a sieve plate is arranged below the liquid collector, and a solvent is arranged in a space between the sieve plate and the bottom of the distillation extraction container. The device is small in size, does not need to be externally connected with cooling water, can be put into a microwave oven for use, effectively shortens the extraction time, prevents the bottom pasting phenomenon, reduces the loss of effective components, saves resources, is simple to operate, is convenient and quick, and improves the distillation efficiency.

Description

technical field [0001] The invention relates to a simple and easy-to-operate microwave-assisted extraction device, which can use microwave-assisted steam distillation to extract plant essential oils, plant natural spices, and volatile components of medicinal materials, and belongs to the technical field of efficient and rapid essential oil extraction. Background technique [0002] Essential oils or volatile components of medicinal materials are volatile aromatic substances extracted by physical or chemical methods from the roots, stems, leaves, flowers or fruits of natural plants. Common extraction methods for plant essential oils, plant natural flavors, and volatile components of medicinal materials include steam distillation, solvent extraction, solid-phase microextraction, and extrusion. The steam distillation method is simple to operate, and the volatile substances are taken out by water vapor without destroying the extracted substances. However, the traditional steam d...
