Embodiment 1

[0031] according to figure 1 The flow chart of the production process of rose water concentrate is shown. After fresh roses are picked, add 13% salt of fresh flowers and marinate them for 20 days. After mixing with demineralized water at a material-to-liquid mass ratio of 1:2.5, add them to a distillation tank for distillation for 4 h. After the distillate is condensed by the condenser, it enters the oil-water separator to stand still, and the rose water is obtained after the essential oil is separated. Take 50 L of rose water stock solution at room temperature, pass through a microfiltration membrane with a pore size of 0.5 μm to remove suspended particles and bacteria to obtain a microfiltration permeate, and use a nanofiltration filter with a molecular cutoff of 400 Daltons to obtain the microfiltration permeate. The filter membrane is filtered to obtain the nanofiltration permeate, and then the nanofiltration permeate is intercepted by the first-stage reverse osmosis membr...

Embodiment 2

[0033] according to figure 1 The flow chart of the production process of the rose water concentrate is shown. After the fresh roses are picked, add 15% of the flower mass salt to marinate for 30 days, mix it with demineralized water at a material-to-liquid mass ratio of 1:3, and then add it to the distillation tank for distillation for 3 h. After the distillate is condensed by the condenser, it enters the oil-water separator to stand still, and the rose water is obtained after the essential oil is separated. Take 50 L of rose flower water at room temperature, pass through a microfiltration membrane with a pore size of 1 μm to remove suspended particles and bacteria to obtain a permeate, and filter the permeate through a nanofiltration membrane with a molecular cutoff of 500 Daltons to obtain a nanofiltration membrane. Filtrate the permeate, and then pass the nanofiltration permeate through the primary reverse osmosis membrane under the operating pressure of 1~2 MPa. Under the...

Embodiment 3

[0036]After fresh roses are picked, add salt with 17% of the mass of flowers and marinate them for 50 days, mix them with demineralized water at a ratio of 1:4 to liquid, add them to a distillation tank for distillation for 2.5 hours, and the distillate is condensed by a condenser and then enters an oil-water separator for standing , rose water is obtained after the essential oil is separated. Take 50 L of rose water at room temperature, pass through a microfiltration membrane with a pore size of 2 μm to remove suspended particles and bacteria to obtain the permeate, and filter the permeate through a nanofiltration membrane with a molecular cutoff of 600 Daltons to obtain nano Filtrate the permeate, and then pass the nanofiltration permeate through the interception of the primary reverse osmosis membrane under the operating pressure of 1~2 MPa. Under the operating pressure of 4 MPa, it is input into the secondary reverse osmosis system for circulation, and the intercepted liqu...

Abstract

The invention discloses a rose water concentrated liquor processing method, and the method belongs to the field of flower water processing technology. A high-quality rose water concentrated liquor is obtained by performing microfiltration, nanofiltration and reverse osmosis concentration at room temperature on a natural flower water generated in an essential oil extracting process. In the processing method, membrane enrichment technology is firstly applied to concentration of volatile aroma components in the rose water for obtaining of a natural flower water concentrated liquor, and thereby a standardized production of the flower water concentrated liquor is realized. The obtained rose water concentrated liquor has the advantages of being low in energy consumption, less in loss of the aroma components, adjustable in concentration multiple according to production demands, and the like; and therefore the industrial production demand of the rose water is satisfied.

Description

technical field [0001] The invention belongs to the technical field of flower water processing, and in particular relates to a method for processing rose flower water concentrate. Background technique [0002] Rose water is a by-product produced during the extraction process of rose essential oil. After the water phase distilled in the process of steam distillation to prepare essential oil is cooled, the oil and water are separated, and the oil phase is rose essential oil; there are still some aromatic components and water-soluble components in the water phase. Sexual substance exists, that is, rose water. Rose water has anti-allergic, anti-inflammatory, antibacterial and bactericidal effects; it also has the effect of cleaning, tightening and lubricating the skin, and has obvious inhibitory effect on facial fever symptoms caused by sunlight ultraviolet rays. Compared with essential oils, flower water has a large market demand and high product added value, which has importa...
