Problems solved by technology

The traditional condensation process is that the oil-water mixture is condensed through a horizontal straight tube condenser, but due to the short condensation time, the condensation effect is low, and the temperature of the distillate is mostly above 50°C, so that many alcoholic aromatic substances cannot be fully analyzed, and the distillate Low liquid yield

Embodiment Construction

[0017] Attached below figure 1 , attached figure 2 , attached image 3 The present invention will be further described.

[0018] The secondary condensation extraction process of rose essential oil adopts the following steps successively:

[0019] (1) put the rose flowers into the distillation pot 1 for distillation to form oil-water mixed steam with a temperature of 95-100°C; (2) send the oil-water mixed steam into the inner cavity of the closed first-stage condenser 2, and the first-stage condenser The cold water pipe 8 in 2 is connected with cold water, and the oil-water mixer forms a distillate with a temperature of 55-70°C after exchanging heat with the cold water pipe 8; (3) Distillate with a temperature of 55-70°C formed in step (2) The effluent is transported to the secondary condenser 3 through the spiral tube 11 arranged in the secondary condenser 3, and cold water is passed into the secondary condenser 3, and the 55-70°C distillate in the spiral tube 11 After ex...

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.

Description

technical field [0001] The invention relates to the technical field of extraction and production of rose essential oil, in particular to a secondary condensation extraction process of rose essential oil and condensation equipment. Background technique [0002] Rose essential oil is the king of natural plant essential oils, widely used in beauty, body, food, tobacco and perfume cosmetic flavoring agents. Rose essential oil processing is divided into three parts: distillation, condensation, oil-water separation, the key link is condensation. The traditional condensation process is that the oil-water mixture is condensed through a horizontal straight tube condenser, but due to the short condensation time, the condensation effect is low, and the temperature of the distillate is mostly above 50°C, so that many alcohols and aromatic substances cannot be fully analyzed, and the distillate Liquid production is low. Contents of the invention [0003] In order to overcome the defi...
