Description

Technical Field

[0001] The utility model relates to the technical field of distillation, in particular to a distillation device for preparing synthetic fragrances. Background Art

[0002] Short-path distillation technology is a new type of liquid-liquid separation technology that has developed along with vacuum technology and distillation technology since the 20th century. Different from general distillation technology, rectification distillation separates different components based on the different free paths between light and heavy molecules. Different from ordinary vacuum distillation, rectification distillation is a completely non-equilibrium distillation. It is a gentle separation method with the characteristics of operating under high vacuum, small distance between evaporator and condenser, short heating time, high degree of separation, low operating pressure, and no solvent residue. It has unique advantages in the separation and purification of multi-component heat-sensitive natural materials.

[0003] The distillation instruments currently available on the market are highly homogenized, and all of them are mainly composed of an evaporator connected to a light-heavy component tank, and then a cold trap in series. However, the flavor material is a mixture, in which the boiling points of each monomer substance vary greatly. If the distillation instruments currently available on the market are used, high-boiling point substances are prone to condensation and aggregation in the pipelines and equipment blockage. When encountering different low-boiling point substances, they cannot be separated, and the operation must be repeated many times. Multiple operations and multiple heating are not conducive to the protection of aroma and taste; and in the current distillation and distillation devices, the light group is doped in the recombinant after distillation, and the light group is doped with the recombinant, resulting in impure ingredients. Utility Model Content

[0004] In view of the problems existing in the existing distillation device for preparing synthetic fragrances, the utility model is proposed.

[0005] Therefore, the purpose of the utility model is to provide a distillation device for preparing synthetic flavors, which solves the serious homogenization of the distillation instruments currently available on the market. The main style is an evaporator connected to a light-heavy component tank, and then a cold trap is connected in series. The flavor material is a mixture, and the boiling points of each monomer substance vary greatly. If the distillation instruments currently available on the market are used, high-boiling point substances are prone to condensation and aggregation in the pipeline to block the equipment. Different low-boiling point substances cannot be separated, and multiple operations must be repeated. Multiple operations and multiple heating are not conducive to the protection of aroma and taste; and the current distillation devices, the recombinant is doped with light components after distillation, and the light components are doped with recombinant components, resulting in impure components.

[0016] The secondary distillation reflux structure further comprises a first suction pump connected to the outlet of the light component tank through a conduit, and the output end of the first suction pump is connected to the first reflux interface of the evaporator through a first reflux pipe.

As the composition of natural fragrances is very complex, including a series of compounds from top notes with very low boiling points to heavy components with very high boiling points such as wax, flavonoids, polyphenols, etc., ordinary distillation distiller can only obtain two components, light and heavy, while the distillation device dedicated to flavor materials can obtain four segmented products, namely heavy components, light components, top notes A, and top notes B. At the same time, by adding a jacket to the outside of the heavy component collection tank inside the evaporator and adding an inclined plane, the heavy component products that are easy to condense can be quickly and smoothly collected in the heavy component storage tank.

[0027] A first interface 41 for feeding is provided at the top of the evaporator 4 , and the first interface 41 is connected to the feeding tank 1 through a conduit.

[0028] Condensate at different temperatures is added to cold trap 1 and cold trap 2 to obtain different top fragrance products.

The fourth interface 44 is used for connecting the primary cold hydrazine 5 and the secondary cold hydrazine 6 . The second interface 42 and the fifth interface 45 are used for connecting the heavy component tank 2 and the light component tank 3 .

[0031] The heating area of ​​the evaporator 4 can be from 0.01m 2 ~10m 2 The size of the cooling area is generally about 0.5 to 1.5 times the heating area.
