Description
(1) technical field
The utility model relates to a kind of preparation facilities of high-purity tea polypenols.
(2) background technology
Tea-polyphenol (Tea Polyphenols) is the general name of polyphenols in the tealeaves, comprises flavanol compound, anthocyanin class, flavonoid, flavonols and phenolic acids etc.The content of tea-polyphenol in tealeaves is generally at 15%-20%.Tea-polyphenol has very strong antioxygenation, and its resistance of oxidation is synthetic antioxidant BHT, BHA 4-6 a times, is 6-7 times of VE, and the 5-10 of VC times, and consumption is few: 0.01-0.03% can work, and does not have the potential toxic side effect of synthetics; And theine has provide protection to pigment in the food and vitamins, makes food keep original color and luster and trophic level in a long time, can effectively prevent the corruption of food, edible oils, and can eliminate peculiar smell.
The traditional method of preparation tea-polyphenol mainly is divided into following three classes from tealeaves.
1. solvent-extraction process floods tealeaves with polar solvent, then leaching liquid is carried out liquid-liquid extraction and separates, and concentrates at last and obtains product.Suitability for industrialized production mainly adopts this method at present.It is that leaching liquid entered evaporator tower evaporation separation after raw material tealeaves was put into the extractor dipping, then through the extraction tower extraction, through bleacher decolouring, concentrated, the lyophilize of thin-film evaporator, obtains finished product successively.Stop up easily in this cover production equipment production process, inefficiency, and the cost height, yield is low, impurity is many.
2. ion precipitation method precipitated metal tea-polyphenol makes it separate with trimethyl-xanthine, and this method has been used the deleterious heavy metal of human body is made precipitation agent, so, reach the requirement of food and medicine industry with the product difficulty of this method production.
3. post separates preparation method gel column, adsorption column and ion exchange column method.Adopt post to separate preparation method, the tea-polyphenol yield is between 4%～8%, and purity can reach 98%, but the column packed material is very expensive, and will obviously be not suitable for suitability for industrialized production with multiple and a large amount of organic solvents during drip washing.
Some problems of the equal ubiquity of above traditional method and drawback, product can't be in the requirement of all satisfying foodstuff additive and pharmaceutical industries aspect security, price and the purity.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of preparation facilities of high-purity tea polypenols is provided, and its cost is low, yield is high, impurity is few, pollution-free, suitable suitability for industrialized production.
The purpose of this utility model is achieved in that a kind of preparation facilities of high-purity tea polypenols, it is characterized in that: it comprises extractor, first surge tank, first step strainer, relay tank, the scraper plate thickener, treatment tank, setting tank, second stage strainer, bleacher, concentration tank, second surge tank, third stage strainer and drying tower, described extractor, first surge tank, first step strainer, relay tank, the scraper plate thickener, treatment tank, setting tank, second stage strainer, bleacher, concentration tank, second surge tank, the setting of connecting successively of third stage strainer and drying tower.
The preparation facilities of the utility model high-purity tea polypenols, described concentration tank are rotating scraper evaporator.
The preparation facilities of the utility model high-purity tea polypenols, described drying tower are spray-drying tower.
The beneficial effects of the utility model are:
The preparation facilities of the utility model high-purity tea polypenols, through three filtration treatment, product impurity is few, the purity height; Adopt the scraper plate thickener to replace conventional retort, adopt rotating scraper evaporator, susceptible to plugging defective when having overcome conventional productions, the production efficiency height, waste little.Adopt spray-drying tower to replace conventional lyophilize, the efficient height, and save cost.Compare with conventional production process equipment that its cost is low, yield is high, impurity is few, pollution-free, be fit to suitability for industrialized production.
