Embodiment 1

[0067] 1. Put the plucked rose petals into the retort, inject water vapor, the first distillation time is 5 hours, then stop the distillation and let it stand for 1 hour. The second pass into steam distillation, distillation time is 3h.

[0068] 2. Pass the distilled steam into the cooling system for condensation to obtain distilled water.

[0069] 3. Pass the distilled water into the oil-water separator. Under low temperature conditions, due to the difference in density, rose essential oil floats on the top and distilled water on the bottom. Rose essential oil is extracted into the essential oil storage container to obtain low concentration rose water.

[0070] 4. The low-concentration rose pure dew obtained above is clarified and decontaminated by a ceramic membrane system to remove suspended solids and insoluble impurities. The pore diameter of the ceramic membrane filter element is 50 nanometers, the channel diameter is 4 mm, and the membrane surface flow rate is 4m / s,...

Embodiment 2

[0073] 1. Put the plucked rose petals into the retort, inject water vapor, the first distillation time is 5 hours, then stop the distillation and let it stand for 1 hour. The second pass into steam distillation, distillation time is 3h.

[0074] 2. Pass the distilled steam into the cooling system for condensation to obtain distilled water.

[0075] 3. Pass the distilled water into the oil-water separator. Under low temperature conditions, due to the difference in density, rose essential oil floats on the top and distilled water on the bottom. Rose essential oil is extracted into the essential oil storage container to obtain low concentration rose water.

[0076] 4. The low-concentration rose pure dew obtained above is clarified and decontaminated by a ceramic membrane system to remove suspended solids and insoluble impurities. The pore diameter of the ceramic membrane filter element is 30 nanometers, the channel diameter is 4 mm, and the membrane surface flow rate is 4m / s,...

Embodiment 3

[0079] The difference from Example 2 is that the dialysis treatment is performed by adding pure water during the treatment process of the ceramic membrane system.

[0080] 1. Put the plucked rose petals into the retort, inject water vapor, the first distillation time is 5 hours, then stop the distillation and let it stand for 1 hour. The second pass into steam distillation, distillation time is 3h.

[0081] 2. Pass the distilled steam into the cooling system for condensation to obtain distilled water.

[0082] 3. Pass the distilled water into the oil-water separator. Under low temperature conditions, due to the difference in density, rose essential oil floats on the top and distilled water on the bottom. Rose essential oil is extracted into the essential oil storage container to obtain low concentration rose water.

Abstract

The invention discloses a hydrolat concentration method and device. The method comprises a hydrolat extraction system, a membrane separation impurity removal system and a membrane concentration system. The method comprises the following steps of 1) putting plant raw materials into a distillation retort, distilling by using steam, condensing the distilled steam into distilled water, and separating essential oil and low-concentration hydrolat by using an oil-water separator to obtain the essential oil and the low-concentration hydrolat which is generated in a form close to colorless distilled water, 2) filtering the low-concentration hydrolat through a ceramic membrane system, and carrying out clarification, impurity removal, sterilization, suspended matter removal, insoluble impurity removal and the like on the low-concentration hydrolat through a ceramic membrane so as to obtain ceramic membrane permeate liquid of the low-concentration hydrolat, and 3) concentrating the ceramic membrane permeate liquid through an organic membrane system so as to obtain high-concentration hydrolat concentrated liquid.

Description

technical field [0001] The invention relates to a method and device for extracting pure dew, belonging to the technical field of plant extraction. Background technique [0002] Hydrosol is called aromatic water or aromatic distilled water, such as rose hydrosol and lavender hydrosol. The solubility of most plant essential oils in water is very small. When steam distillation is used to prepare essential oils in actual production, some plant essential oils and some small molecule aromatic substances will dissolve in water. For example, when preparing rose essential oil, its main aroma components Phenylethyl alcohol will partially dissolve in water to form rose water. Rose Hydrosol is not mixed with any fragrance, moisturizer, preservative, etc. It is a pure natural product, so it is particularly gentle and safe. Rose hydrosol contains a large amount of volatile aromatic components of roses, and its components are particularly complex, with about 300 kinds, mainly including...
