Abstract

The invention discloses a conveying device for extraction of taxol by using branches and leaves of Chinese yew. The conveying device comprises a conveying hopper (7), a vacuum suction pipe (10), a support (1), a screening device and an agitating device, wherein the screening device comprises a screen basket (2) with meshes (3), a lifting chain (4) and a vibrating mechanism (5); the agitating device comprises a motor (6), an agitating shaft (9), a middle agitating blade (8) and a bottom agitating blade (11). By applying the conveying device, mechanical and automatic screening, feeding and conveying operation can be realized, thus the labor intensity is effectively reduced, the operation process is simplified, the working efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of paclitaxel extraction, and in particular relates to a feeding device for extracting paclitaxel from yew branches and leaves. Background technique [0002] Taxus has excellent medical value, which is mainly reflected in the extraction of the anticancer substance paclitaxel. Paclitaxel has the function of inhibiting tumor growth, and is a broad-spectrum and highly active anticancer drug recognized worldwide. Due to its unique mechanism of action and remarkable efficacy, paclitaxel has gradually been widely used in the clinical treatment of lung cancer, ovarian cancer, and breast cancer. Paclitaxel resources are scarce and expensive, and its efficient extraction has become the focus of research in the pharmaceutical industry. At present, paclitaxel is mainly extracted from yew plant raw materials. The existing common method for extracting paclitaxel from yew plant raw materials is to first obtain crude pa...
