Hot reflux extraction enrichment equipment is currently use more extraction enrichment facilities.
Hot reflux extraction unit product features:
1, combining the existing extraction and reflux extraction, enrichment equipment to extract extracted diacolation and type three principles, combined with external heat circulation enrichment technology, the extraction and enrichment process focused on one device at the same time;
2, concentration of secondary steam was into the extracting tank as a new heat extraction, maintain the extraction of the extraction tank temperature;
3, extraction tank of steam into the return condensation into hot condensate falling into the extracting tank, as a new solvent evenly to the medicinal materials, a new solvent by medicinal material layer from top to bottom, dissolve the medicinal materials to extract soluble substance in the tank bottom, eliminate cold heap, herbs extraction.
Extract into the concentrator, continuously reduce the concentration of the extracting tank liquid is poor, maximizing effective into yield;
Because of low solvent consumption, less concentrated liquid, extraction and enrichment process time is short, to save energy.
The use of hot reflux unit attention:
1, the applicator should be determined by verifying the medicinal materials supply, hot reflux extraction principle determines the inventory than multi-purpose extraction tank inventory;
2, according to the concentration of liquid reflux time to start.
Reflux time soon to extract low concentration will extend the effective extraction time, return time is too late, extract concentration saturation is bad for the extraction of effective components, also waste energy.
Should after extraction (boiling) 1 h, condensed the part of the liquid in the tank, flowing back and timing.
Note that extract should rule out the air in the tank when the pot boiling, or tank will produce pressure;
3, want to control the temperature of the backflow, don't too low.
To control the temperature of the extracting tank at the same time, try to keep constant temperature, cold (90 ℃) less impurity, good clarity, heat with high efficiency, clarity is poor.
Boiling purpose is to strengthen the solution of the diffusion and osmosis, boiling, though can again in a short period of time the concentration of a solution of narrow difference, but will make many macromolecular impurities dissolution;
4, to determine the extraction enrichment time.
Excessive extraction separation will add to extract the impurities to the late increase the difficulty, the time is too short to extract incomplete, waste of raw materials (should be in the process of extracting test solution concentration).
Traditional Chinese medicine extraction enrichment should be it is worth noting: when the multi-function extractor process operation, medicinal herbs can be formed at the bottom of the extracting tank cold heap, decrease the extraction of effective components, a waste of medicinal materials.
