Abstract

The invention relates to the technical field of extraction equipment, in particular to a low-temperature subcritical fluid extraction device. The low-temperature subcritical fluid extraction device comprises a feeding pipe, an extraction tank and a discharging pipe; the feeding pipe is connected to the feeding opening of the extraction tank; the discharging pipe is connected to the discharging opening of the extraction tank; the feeding pipe comprises a feeding pipe body with a closed upper end and an opened lower end, and a feeding rotating shaft arranged in the feeding pipe through a bearing; the upper end of the feeding rotating shaft is connected with a feeding motor for driving the feeding rotating shaft to rotate; a feeding forward spiral and a feeding reverse spiral are arranged on the feeding rotating shaft in the axial direction from top to bottom sequentially; a gap is reserved between the feeding forward spiral and the feeding reverse spiral. According to the device, through the forward and reverse spiral feeding structure, the advantage that continuous material feeding can be realized for uninterrupted extraction is achieved.

Description

technical field [0001] The invention relates to the technical field of extraction equipment, in particular to a low-temperature subcritical fluid extraction device. Background technique [0002] Supercritical CO 2 Extraction is an emerging low-temperature extraction technology for active ingredients, which has CO 2 As a solvent, it is non-toxic, odorless, and non-flammable, and the product has no organic solvent residue; the extraction conditions are relatively mild, and the activity of natural active ingredients can be retained to the greatest extent. However, in order to achieve higher extraction efficiency, supercritical CO 2 The extraction pressure generally needs to be higher than 30MPa, which requires high equipment, and it is difficult to realize continuous production, which requires large investment in equipment and high energy consumption in operation. Due to various problems existing in supercritical extraction technology at this stage, it is difficult to apply ...
