Abstract
The utility model relates to a precipitation filtration system used in a tea polyphenol production process. The precipitation filtration system is characterized by comprising a settling kettle (1) and a bag filter (2), wherein a stirring apparatus (1.2) is arranged in the settling kettle (1), a jacket (1.1) is arranged outside the settling kettle (1), a temperature measurer (1.3) is also arranged on the settling kettle (1), a bending pipe (1.4) is also arranged inside the settling kettle (1) and is connected to one end of a liquid outlet pipe orifice of the settling kettle (1) through a rotating joint, and the other end of the liquid outlet pipe orifice is connected to a liquid inlet of the bag filter (2). The precipitation filtration system used in the tea polyphenol production process has the advantages that the centrifugal setting is abandoned, the energy consumption is low, no bubbles are generated, the material loss is low, the liquid discharging is convenient, the impurity removal is complete, and the slagging is convenient.
Description
Technical field
The utility model relates to the sedimentation and filtration system in a kind of Tea Polyphenols production process.
Background technology
Tea Polyphenols (Tea Polyphenols) is the general name of Polyphenols of Tea, comprises flavanol compound, anthocyanin class, flavonoids, flavonols and phenolic acid class etc.The content of Tea Polyphenols in tealeaves is generally at 15%-20%.Tea Polyphenols has very strong antioxidation, its oxidation resistance be artificial synthetized oxidation preventive agent BHT, BHA 4-6 doubly, be the 6-7 of VE doubly, doubly, and consumption is few for the 5-10 of VC: 0.01-0.03% can work, and without the potential toxic and side effect of synthetic; And theine has protective effect to the pigment in food and vitamins, make food keep in a long time original color and luster and trophic level, the corruption of food, edible oils can be effectively prevented, and peculiar smell can be eliminated.
Prepare Tea Polyphenols from tealeaves, suitability for industrialized production mainly adopts solvent extraction method at present, is about to ethyl acetate polar solvent dipping for tealeaves, then leaching liquid is mixed with water and carries out liquid-liquid extract and separate, makes Tea Polyphenols turn molten to water, finally the concentrated product that obtains.Turn in molten process to water at Tea Polyphenols, in the aqueous solution, can have more insoluble substance, as protein, pectin, leaf green, insoluble tea fiber etc., need to remove, make the solution clarification.The method of removing at present insoluble substance adopts sedimentation centrifuge to remove, and the defect of this removing method is: one, energy consumption is high; Two, can produce a large amount of foams in the centrifugal treating process, loss of material is large; Three, impurity is processed unclean.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of energy consumption is low, non-foam, loss of material are little, the Impurity removal sedimentation and filtration system in the Tea Polyphenols production process thoroughly.
The purpose of this utility model is achieved in that the sedimentation and filtration system in a kind of Tea Polyphenols production process, it comprises sedimentation still and bag filter, be provided with agitating device in described sedimentation still, outer setting has chuck, also be provided with temperature measurer on described sedimentation still, also be provided with bending tube in described sedimentation still, it is connected with the fluid mouth of pipe one end of sedimentation still by swivel joint, and the described fluid mouth of pipe other end is connected with the bag filter inlet.
The bending angle of described bending tube is 30-60 °, is preferably 45 °.
The beneficial effects of the utility model are:
Sedimentation and filtration system in the utility model Tea Polyphenols production process, do not adopt centrifugal setting, and energy consumption is low and can not produce foam, and loss of material is little, and fluid is convenient, and Impurity removal is thorough, residue-discharge convenience.
The accompanying drawing explanation
The structural representation that Fig. 1 is the sedimentation and filtration system in the utility model Tea Polyphenols production process.
Wherein:
Sedimentation still 1, bag filter 2, chuck 1.1, agitating device 1.2, temperature measurer 1.3, bending tube 1.4.
The specific embodiment
Referring to Fig. 1, the utility model relates to the sedimentation and filtration system in the Tea Polyphenols production process, mainly by sedimentation still 1 and bag filter 2, formed, be provided with agitating device 1.2 in described sedimentation still 1, outer setting has chuck 1.1, and slag-drip opening is arranged on bottom, also be provided with temperature measurer 1.3 on described sedimentation still 1, also be provided with bending tube 1.4 in described sedimentation still 1, it is connected with the fluid mouth of pipe one end of sedimentation still 1 by swivel joint, and the described fluid mouth of pipe other end is connected with bag filter 2 inlets.
The bending angle of described bending tube 1.4 is 30-60 °, is preferably 45 °.
In use procedure, open agitating device 1.2, pass into cold medium in chuck 1.1, by chuck is cooling, the interior fluid temperature of sedimentation still 1 is cooled to 40-45 ℃, staticly settle 1-2h, at this temperature, at the bottom of making insoluble impurities be precipitated to still, sedimentation still 1 top clarified solution flows into bag filter 2 by the fluid mouth of pipe and is filtered.When the interior liquid level of sedimentation still 1 is higher, adjust swivel joint, make bending tube 1.4 suspend and hold setting upward, away from bottom sedimentation residue, then along with liquid level reduces, constantly adjust swivel joint, make bending tube 1.4 in the situation that guarantee to draw clarified solution, away from bottom sedimentation residue, guarantee separating effect to greatest extent.
