Abstract

The invention relates to the technical field of extraction, and particularly relates to ultrasonic reflux extraction and concentration equipment. The equipment comprises a rack, wherein an ultrasonic extraction tank, an extracting solution intermediate filtering tank, an evaporation and concentration kettle, a condenser and a solvent storage tank are fixedly arranged on the rack; and a feeding hopper is arranged on the upper surface of the ultrasonic extraction tank, the solvent storage tank is arranged on the rack beside the ultrasonic extraction tank, a first liquid suction pump is arranged beside the solvent storage tank, and the liquid inlet end of the first liquid suction pump is connected with a liquid suction pipe extending into the solvent storage tank. Compared with an existing plant extraction and concentration unit, diffusion of effective components in the ultrasonic extraction tank can be accelerated through the arranged ultrasonic vibrator, so that the extraction utilization rate of the effective components is increased; due to the arrangement of a return pipe, the extracted solvent can be repeatedly utilized, and waste of the solvent during extraction of effective components in plants is effectively avoided; in addition, extraction and discharging are convenient, the whole concentration process is high in speed, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of extraction and extraction, in particular to an ultrasonic reflux extraction and concentration equipment. Background technique [0002] The extraction of active ingredients of plant and animal materials is mainly carried out by solvent dissolution and separation and concentration, that is, according to a certain solid-liquid ratio, the materials to be extracted are put into the extraction device together with solvents such as water or other organic solvents. The effective components of the material are extracted at a certain temperature. At present, the traditional plant concentration extraction unit has low efficiency for the active ingredients in plants. At the same time, the concentration tank in the plant concentration extraction unit has uneven heating temperature during concentration, which not only leads to low concentration efficiency, but also uneven heating temperature will cause the temperature...

At present, the traditional plant concentration extraction unit has low efficiency for the active ingredients in plants

At the same time, the concentration tank in the plant concentration extraction unit has uneven heating temperature during concentration, which not only leads to low concentration efficiency, but also uneven heating temperature will cause the temperature of the plant extract in some areas to be too high, while the extraction of some areas The temperature of the liquid is lower, thereby destroying the active ingredients of the plant concentrate to be extracted

[0003] For example, the patent No. CN105709456A discloses an ultrasonic thermal reflux extraction and concentration unit, which includes an electric control device and a vacuum concentration device successively installed on an integrated frame, an extraction device, a solvent recovery device, and a vacuum in the vacuum concentration device. The concentration tank is equipped with a concentration agitator, and the extraction tank of the extraction device is equipped with an agitator and an ultrasonic generator to extract the material forcibly. The solvent recovery device forms a communication pipeline with the extraction device through a pipeline, and the solvent circulates in the unit to reduce the material. For extraction, the oil-water separator can also extract and separate aromatic oil; the ultrasonic heat reflux extraction and concentration unit makes the extraction of active ingredients in plants more fully through ultrasonic extraction, and its reflux setting enables the extraction solvent to be recycled, which greatly saves solvent However, after the ultrasonic extraction in the ultrasonic extraction tank of the device is completed, the plant slag is not easy to discharge, requiring personnel to enter the extraction tank for cleaning, which greatly increases the difficulty of cleaning; When the extract is evaporated and concentrated, the heating effect is uneven and the heat preservation effect is poor. Not only is the concentration efficiency low, but also the heat preservation effect is poor, which will cause a large amount of heat to be emitted during the evaporation and concentration process, which increases power loss and cannot achieve energy saving and emission reduction.
