Description

A kind of energy-saving and water-saving joint material reduces discharging extraction concentration device

Technical field

The utility model relates to a kind of enrichment facility, and particularly a kind of energy-saving and water-saving joint material reduces discharging extraction concentration device.

Background technology

At present, known Chinese medicine, food additives production industry, be to adopt the multipotency jar to endure out soup, precipitate through settling tank, filter filters, inspissator concentrates, carry out successively, multistep is finished liquid extract production, and there is following drawback in this process equipment: 1, decoct medicinal herbs: decoct medicinal herbs with the multipotency jar, be heated to more than the boiling point to extract in chuck with primary steam (Boiler Steam), a jar interior band is pressed, contain in medicinal material and solvent under the low gradient of soluble substance density and extract, the soluble substance dissolution rate is slow, time is long, and leachable is few.In order to improve the yield of leachable, and increase extraction time (2～3 times), increase solvent load to 12～20 times medicinal material amount.Solvent load is big, consume high, organic solvent is expensive, the cost height, and the pharmaceutical factory is with not rising, and many waters are carried, indissoluble or water-fast effective component do not put forward (have only sugar, amino acid, protein and a small amount of glycoside in the Chinese medicine, be dissolved in soluble in water, and alkaloid, biological ketone, terpene, sterol, biotin is all water insoluble and be soluble in organic solvent), it is few or do not contain to contain the drug effect composition in the medicine, so uncertain therapeutic efficacy is cut.Solvent load is big, and the energy consumption height pollutes greatly, and water consumption is big.(in the production of 1T medicinal material, T is a ton, down together); 1 times of solvent load of every increase, just 1T extracts that concentrate more, then many with 1.18T steam (thermal efficiency 85%), produce CO ₂=1.18T80% * 44/12=3.5T (80% burning C) is many with 27T water " 1T * 539 kilocalories/kg ÷ (1 kilocalorie/kg ℃ * 20 ℃) (water temperature rises 20 ℃); 2, concentrate: because Chinese medicine contains carbohydrate, glycoside is many, easily produces foam.The reason that foam produces is: often discharge condensed water in concentrating, vacuum is changed greatly, vacuum improves, and the concentrate boiling point descends, and former concentrated temperature has the boiling point of reaching or surpasses boiling point.At this moment liquid internal fiercely evaporates and the generation steam bubble; Steam bubble rises on the liquid level, because liquid has surface tension, surface tension is during greater than the steam bubble internal pressure, and steam bubble does not break, and a large amount of steam bubbles forms foam.Deal with improperly and just run material, run material and will reclaim, both caused medicine pollution, again contaminated environment.In order to overcome in extract concentrating: 1. solvent load is big, consumes high; 2. the energy consumption height pollutes big; 3. the multipotency jar is two pressure solution devices, has limited the expansion of volume.Many for overcoming concentrated middle foam, the material that run pollute problem more.

Summary of the invention

The purpose of this utility model provides a kind of energy-saving and water-saving joint material and reduces discharging extraction concentration device, it not only reduces solvent load, cut down the consumption of energy, and can make Chinese medicine, the food additives production industry of high energy consumption, high pollution change energy savings, resource-type industry into, remove many, less, poor, random cap, form the monopoly enterprise of ten thousand tons of medicinal materials of inventory 2-4.

Solve the technical scheme of the utility model technical problem: the utility model comprises extractor 5, inspissator 13, return channel 1 and liquid extract collecting tank 14, extractor 5 is by hot condensate line 4, steam pipe 10 is connected with return channel 1, extractor 5 is by extracting clear liquid pipe 8, extract pipe 9 respectively with basin 7, inspissator 13 links to each other, inspissator 13 is by secondary steam pipe 12, steam pipe 10 links to each other with return channel 1, form and extract the concentrated EGR that refluxes, be with extraction, filter, concentrate and carry out synchronously, once finish the cover stainless steel full-sealing device that liquid extract is produced, this device adopts no chuck extractor, do not produce the outer heat-circulation type inspissator resurgent board-like return channel close with the indirect steam temperature of foam with the phegma temperature.

The good effect of the utility model and corresponding technology is: one ton of medicinal material proposes liquid, can reduce solvent load more than 10 tons, saves 11 tons of steam, and 1.83 tons in folding coal reduces CO ₂5.4 tons of discharge capacitys.Can save time, improve concentrate recovery rate 15～20%.
