Problems solved by technology

[0003] At present, natural plants are mainly extracted by heating with organic solvents. This method is not efficient, consumes a lot of time and energy, and often not only causes damage to heat-sensitive components in plant materials, but also brings out many impurities, which increases the subsequent separation. Purification process increases consumption and production costs

Embodiment 1

[0059] Embodiment 1: the extraction of oil and fat in chlorella

[0060] 1) Put the mass ratio of concentrated chlorella algae: water = 1:10, open the C-shaped clamp, start the lifting device, pour the mixture into the tank of the homogenizer, the total volume is 2 / 3V of the tank, and then rise tank and seal the tank.

[0061] 2) Start the anchor stirrer at a speed of 80r / min, and at the same time start the circulating water bath, control the temperature of the mixed material in the stirring tank to about 60oC, turn on the rotary blade 11 after 3 minutes, and stir at a speed of 150r / min for 5 minutes.

[0062] 3) Turn on the high-speed shear agitator, set the speed to 15000r / min, and turn on the ultrasonic generator at the same time, the ultrasonic power is 150W, and the frequency is 20KHZ.

[0063] 4) After working for 25 minutes, stop the high-speed shear agitator 9 and the rotary blade 11, set the temperature of the circulating water system at room temperature around 25oC,...

Embodiment 2

[0068] Embodiment 2: the extraction of orange peel essential oil

[0069] 1) Open the C-shaped clamp with the concentrated orange peel 1:15 (mass ratio orange peel: deionized water), start the lifting device, pour the mixture into the tank, the total volume is 3 / 4V of the tank, and then lift the tank body and seal the tank.

[0070] 2) Start the anchor agitator at a speed of 100r / min, and at the same time start the circulating water bath control, the temperature of the mixed material in the mixing tank is about 60oC, turn on the blade 11 after 3 minutes, the speed is 200r / min, and stir for 5 minutes.

[0071] 3) Turn on the high-speed shear agitator, set the speed to 15000r / min, and turn on the ultrasonic generator at the same time, the ultrasonic power is 200W, and the frequency is 20KHZ.

[0072] 4) After working for 30 minutes, stop all parts, first stop the high-speed shear agitator 9 and the rotating blade 11, then stop the high-speed shear and ultrasonic action, open th...

Abstract

The invention discloses an extraction method of a plant active ingredient, which comprises the following steps of: cleaning up the to-be-extracted plant, wherein the mixing mass ratio of the plant to the deionized water is (1:3)-(1:10); starting a lifting device to pour the mixture into a tank body and sealing; starting an anchor agitator, and starting a circular water bath and a rotary blade at the same time; starting a high-speed shearing agitator, and starting an ultrasonic generator at the same time; stopping agitating and the ultrasonic generator, extracting upper-layer petroleum ether, and discharging lower-layer mixture through a discharge port; and performing reduced pressure distillation and concentration of the extraction liquid to obtain the required active ingredient. The method disclosed by the invention quickly damages the cell structure by use of ultrasonic technology and high-speed shearing so that the active ingredient is released, the time is short, the output is high and the energy consumption is low; and a circulating water system is adopted to accelerate the extraction process, the efficiency is improved, and the medicine property of precious Chinese herbal medicine is well maintained.

Description

technical field [0001] The present invention relates to a chemical extraction method, in particular to an extraction method of plant active ingredients, mainly aimed at the extraction of crude oil, and can also separate and extract other water-soluble ingredients. The effective ingredients of the plant are the saturated and Unsaturated fatty acids are widely used in the preparation of biodiesel and in the fields of food and medicine. Background technique [0002] Extracts of plant active ingredients have great economic value, and are widely used in medicine, cosmetics, food and other industries. The extraction of active ingredients from natural plant materials is an important method and link. [0003] At present, natural plants are mainly extracted by heating with organic solvents. This method is not efficient, consumes a lot of time and energy, and often not only causes damage to heat-sensitive components in plant materials, but also brings out many impurities, which incre...
