Abstract
The invention relates to a secondary condensation extraction process and condensation equipment for rose essential oil. The secondary condensation extraction process comprises the steps as follows: formed oil-water mixed vapor firstly enters the inner chamber of a closed primary condenser for condensation so as to form distillate with the temperature of 55-70 DEG C; then the distillate with the temperature of 55-70 DEG C is transported to a secondary condenser for secondary condensation through a spiral pipe spirally distributed inside the secondary condenser, so as to form distillate with the temperature of 25-35 DEG C; the distillate with the temperature of 25-35 DEG C is finally transported to an oil-water separator, so that the rose essential oil is obtained finally. According to the invention, through two-time condensation, the oil yield of the rose essential oil is increased to 0.028% from 0.024%, which is obtained by using a horizontal type straight tube condenser for condensation, the output rate of the rose essential oil is improved, ingredients such as trans-oxidation rose, cis-oxidation rose, alpha-terpilenol, beta-phenethyl alcohol, 2,7-dimethyl-1-octanol and geraniol formate in fresh roses are separated out effectively, so that the quality of the rose essential oil is improved, and the ingredient range of the rose essential oil conforms to international rose essential oil standards.

Embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the present invention will be further described for accompanying drawing 3.
This Flos Rosae Rugosae quintessence oil time condensation extraction process adopts following steps successively:
(1) fresh rose flower is dropped into to still kettle 1 and distilled, the oil mixing with water vapour that formation temperature is 95-100 ℃; (2) oil mixing with water vapour is sent in the inner chamber of first-stage condenser 2 of sealing, the cold water pipe 8 in first-stage condenser 2 is connected cold water, the distillate that after oil-water mixer and cold water pipe 8 heat exchange, formation temperature is 55-70 ℃; (3) distillate that temperature step (2) formed is 55-70 ℃ is delivered in secondary condenser 3 by the spiral tube 11 that is arranged on the helical disk cloth in secondary condenser 3, pass into cold water in secondary condenser 3, the distillate that after ℃ distillate of the 55-70 in spiral tube 11 and cold water heat exchange, formation temperature is 25-35 ℃; (4) distillate that is 25-35 ℃ by temperature is delivered to water-and-oil separator 5 and finally obtains Flos Rosae Rugosae quintessence oil.Oil mixing with water vapour becomes the high temperature distillate of 55-70 ℃ after by first-stage condenser 2, the spiral tube 11 of flowing through again afterwards in secondary condenser 3, because spiral tube 11 is spiral, therefore the flow through distance of high temperature distillate in spiral tube 11 increases, the heat exchanger time length of side, thereby can make the high temperature distillate finally become the low temperature distillate that temperature is 25-35 ℃, the temperature of distillate makes the oil yield of Flos Rosae Rugosae quintessence oil bring up to 0.028% by 0.024% of the horizontal straight tube condenser condenses of employing after separating by water-and-oil separator 5 after reducing again, and the condensation time short-range missile of traditional technology causes the distillate temperature more than 50 ℃, a lot of alcohols aromatoising substances can't fully be separated out.And, by after 2 condensations, because the distillate condensation effect is good, the distillate temperature is low, thereby the geraniol in Flos Rosae Rugosae quintessence oil becomes 40%-45% by original 48%-55%, and Geraniol becomes 10%-15% by original 15%-20%.And with respect to traditional technology, trans rose oxide, cis rose oxide, а-Terpineol 350, bata-phenethyl alcohol, 2, the compositions such as 7-dimethyl-1-octanol and geraniol formate are effectively separated out, and the Flos Rosae Rugosae quintessence oil quality is improved, and composition range meets international Flos Rosae Rugosae quintessence oil standard.
