Embodiment 1

[0037] This example is a pilot test for the extraction and concentration of Radix isatidis. Take 200 kg of crude extract from the extraction device 1, centrifuge it in a sedimentation centrifuge to obtain a clarified liquid, cool the clarified liquid to 35°C and enter the concentration circulation tank 5, and remove the clarified liquid from the clarified The liquid is pumped into the microfiltration device (the pore size is 2 μm), and the permeate enters the membrane concentration device, and is concentrated in circulation for 20 minutes to obtain the concentrate and water solvent (permeate). The specific analysis results are shown in the table below.

Abstract

The invention discloses an energy-saving concentration process for extracting active ingredients of plants and a concentration device thereof. The process of the invention comprises the steps of solvent extraction, centrifugal separation, filtration and film concentration. The concentration device comprises an extraction device, a centrifugal separation device, a filtration device and a film concentration device which form a closed circulation system. By using a film centrifugal separation technology for replacing the evaporation method of the prior art for concentrating, the concentration device of the invention has the advantages of simple structure and high working efficiency; the active ingredients of plants are concentrated without being heated; compared with the prior art, the energy is saved by more than 90%; and simultaneously, oxidative degeneration and loss of the active ingredients are reduced, the extraction rate is higher, and the quality is better. In the invention, a closed process system of extraction, separation and concentration is formed, and a heat exchange device is arranged in the closed process system, thereby being favorable for improving the utilization rate of heat energy.

Description

Technical field: [0001] The invention belongs to the technical field of biological separation and extraction, specifically relates to the extraction technology of plant active ingredients, and more specifically relates to an energy-saving and energy-saving method for extracting plant active ingredients based on membrane separation technology, which can effectively prevent the loss of oxidative denaturation of active ingredients during the extraction process. Process and its concentration unit. Background technique: [0002] The existing technology for extracting active ingredients of plants is to first place the plants in an extraction tank for heating extraction, usually water extraction or ethanol extraction for one or two times, and the extract is subjected to centrifugal clarification or filtration and then evaporated under reduced pressure to obtain the extract. The water extraction and alcohol precipitation method used in the prior art also needs to evaporate ethanol t...
