Description
Technical field the present invention relates to a kind of instrument that extracts Rosa Damascana from rose, specifically a kind of pressure-reduced rectification instrument with rotary evaporation.
The background technology bitter water rose is one of China's four big rose strains, and very high economy, ecology and ornamental value are arranged.For a long time, local method equipment and steam distillation are mainly adopted in the production of attar of rose.The former makes the fragrance loss of attar of rose very big, and with offending smell, and well cuts is a lot, the color and luster muddiness, and easily oxidation is spoiled, has lost the characteristic perfume of attar of rose.Steam distillation, the attar of rose color of distillation is darker, fragrance not just, oil yield is also lower, Water in oil divide and wax more, perfume (or spice) almost without a head, oily smell dashes, have in addition pungent arranged.These problems have had a strong impact on the reputation and the development of bitter water rose.Above-mentioned traditional diamond-making technique all will add 3～4 times of water, and after the distillation, nutritional labeling in the rose and pigment are all destroyed, can not continue to utilize, and the discharge of wastewater of production pollutes environment.The inventor is through for many years development, seek a kind of new technology of extracting Rosa Damascana with the normal temperature low pressure method, the Rosa Damascana fragrance that extracted nature, the content of moisture and wax is extremely low, also can obtain outside the Rosa Damascana such as other serial rose products such as oleoptene, rose absolutes.Isolate Rosa Damascana for rectifying from the thick oil of rose, develop and to adapt to the pressure-reduced rectification instrument with rotary evaporation that satisfies technological requirement.
Summary of the invention the object of the present invention is to provide a kind of simple in structure, evaporation efficiency is high, rectification effect is good pressure-reduced rectification instrument with rotary evaporation, use this rectifying instrument, use the Rosa Damascana that the normal temperature low pressure method extracts, as clear as crystal, the fragrance nature, the moisture and the wax that contain denier, it is more to have overcome traditional attar of rose moisture and wax, easily the spoiled defective of oxidation.
For achieving the above object, the technical scheme that the present invention takes is as follows: a kind of pressure-reduced rectification instrument with rotary evaporation comprises rectifying instrument, condenser; The rectifying instrument comprises muff and the filling extract rectification post that places in the muff, and muff is provided with the import and the outlet of thermal liquid, and filling extract rectification post lower port is equipped with decelerator; Condenser is positioned at the top of rectifying instrument; Condenser comprises housing and places the interior two snake condensers of housing, filling extract rectification post upper port communicates with the housing of condenser, and suction mouth is established in the housing upper end, and material outlet is established in the housing lower end, vacuum cock is housed on the material outlet, and lower housing portion is established condensing water inlet and condensation-water drain.
Decelerator comprises motor, shell, end cap, worm and gear assembly and glass tube; The shell right-hand member is installed end cap, the worm and gear assembly is installed in the enclosure, motor output shaft connects worm screw, worm gear is provided with axially extending bore, installs glass tube in the through hole, and the left end of glass tube is positioned at the housing outside and is provided with the frosted mouth, the right-hand member of glass tube joins by being installed on the sealing shroud and the tube connector that are positioned at the end cap outside, tube connector left end outer wall is equipped with the fixed cap of fixedlying connected with end cap, the end cap right-hand member, and the tube connector other end is connected with filling extract rectification post lower port.
During use, pour the thick oil of rose into round-bottomed flask; The round-bottomed flask outlet is fixedly connected on glass tube; Round-bottomed flask is placed in water-bath; The import and the thermal water source of muff thermal liquid are joined; The suction mouth of two snake condensers is connected with vavuum pump; The cooling water inlet and the cooling water source of two snake condensers join; Open cooling water, open vavuum pump; Start motor then; Because glass tube is packed on the worm-wheel shaft, the worm-wheel shaft rotation drives the round-bottomed flask rotation, about 4～6min, Rosa Damascana drips from the liquid outlet of two snake condensers, the place connects container at liquid outlet, receive Rosa Damascana, round-bottomed flask is remaining to be rose absolute.
Because of round-bottomed flask rotates in water-bath under the at the uniform velocity drive of worm gear, the thick oil of the rose in the round-bottomed flask strengthens with the contact area of round-bottomed flask, accelerates the evaporation rate of the thick oil of rose.
The present invention is simple in structure, the Rosa Damascana fragrance nature of extraction, and the content of moisture and wax is extremely low.The present invention also can be used for other material and extracts.
