Embodiment 1

[0039] Embodiment 1: extract peppermint essential oil and hydrosol with device of the present invention, device such as figure 1 , image 3 , Figure 4 As shown, it includes a closeable evaporator 1 with a raw material bed 2 inside. The top of the evaporator is connected to the inlet of a two-stage air pump 3, and the outlet of the air pump is connected to the cold side of the semiconductor refrigeration device. The semiconductor refrigeration device consists of three stages of semiconductor refrigeration. The refrigerators 4 (each refrigerator is a first-stage refrigeration unit) are connected in series, and the flow direction of the cold-side flow is sequentially from the first stage to the third stage. At the cold-side flow inlet of the first-stage to second-stage semiconductor refrigerators, there is a return flow jumper 5 with a valve, which is connected to the hot-side flow inlet of the current-stage semiconductor refrigerator. The outlet of the cold side of the final ...

Embodiment 2

[0041] Embodiment 2: extract peppermint essential oil and pure dew device as embodiment 1, there are 3 stages of semiconductor refrigeration units, at the 1st stage and the 2nd stage semiconductor refrigeration unit hot side outlets, respectively establish inter-stage condensate tank 15 ( See Image 6 ). There are return pipelines with valves from the bottom of the product collection tank to the second-stage condensate tank, and from the bottom of the second-stage condensate tank to the first-stage condensate tank. And the heights of the product collection tank, the second-stage condensate tank, and the first-stage condensate tank are 1.8 meters, 1.0 meters, and 0.2 meters in order, so that the condensate in the three tanks can have sufficient potential difference to flow back step by step , improve the clarity of product cutting, in addition in one or more condensate tanks, add fractionation tower section 15 (see Figure 7 ), the reflux flows in from the top of the tower se...

Description

technical field [0001] The invention relates to a device for extracting active ingredients from plants. Specifically, it uses gas heating, condensation and circulation to extract plant essential oil in stages. Background technique [0002] Plant essential oils, also known as aromatic oils and volatile oils, are important natural spices. In the extraction of plant essential oils, the methods commonly used include distillation, extraction, pressing, leaching, adsorption, etc., among which steam distillation is the most common, and this method often produces components due to hydrolysis, thermal decomposition or other side reactions. Undesirable impurities or damage to effective components, and higher energy consumption. The extraction of plant essential oils by organic solvent extraction not only consumes solvent, but also the extraction solvent may bring impurities into the product. At the same time, equipment for solvent recovery is required, and the device is relatively c...
