Rose essential oil and rose pure dew extraction equipment

Abstract

The invention discloses extraction equipment for rose essential oil and rose hydrosol which mainly includes a distillation still, a steam conduit, a condenser and an oil-water separator, wherein, the distillation still is connected with the oil-water separator by the steam conduit and the condenser; the lower end of the interior of the distillation still is provided with a steam heating coil; and the upper part of the steam heating coil is provided with a transverse plate sieve which can be opened freely. An adsorption plant is arranged between the top of the distillation still and the steam conduit and internally filled with active ceramic rings serving as an absorbent. The extraction equipment of the invention has the advantages of simple operation, convenient use and high production efficiency, and can greatly enhance the quality of the rose essential oil and the rose hydrosol.

Description

Technical field: [0001] The invention discloses a production equipment for extracting rose essential oil and rose pure dew from roses. Background technique: [0002] At present, the production equipment used by most rose essential oil and rose pure dew production enterprises adopts the method of directly passing water vapor into the distillation kettle to heat and distill the mixed roses and water. This kind of production equipment has the following aspects Problems: (1), the pressure steam temperature is usually between 110 ~ 145 ℃, such high temperature steam can easily cause partial overheating of roses, resulting in the destruction of nutrients, and produce peculiar smell and impurities, affecting the aroma of rose essential oil. At the same time, Pressure steam brings in a lot of water during the heating process, which affects the concentration and quality of rose water; (2), during the cooking process of roses in water, a lot of nutrients will dissolve in water, and th...

[0002] At present, the production equipment used by most rose essential oil and rose pure dew production enterprises adopts the method of directly passing water vapor into the distillation kettle to heat and distill the mixed roses and water. This kind of production equipment has the following aspects Problems: (1), the pressure steam temperature is usually between 110 ~ 145 ℃, such high temperature steam can easily cause partial overheating of roses, resulting in the destruction of nutrients, and produce peculiar smell and impurities, affecting the aroma of rose essential oil. At the same time, Pressure steam brings in a lot of water during the heating process, which affects the concentration and quality of rose water; (2), during the cooking process of roses in water, a lot of nutrients will dissolve in water, and these substances will decompose and destroy when encountering high temperature in water , produce peculiar smell and enter rose essential oil and rose pure dew, thereby affecting product quality; (3) Most of the production equipment does not install adsorption devices, and a few production equipment with adsorption devices use activated carbon as the adsorbent. Because the activated carbon particles are too small, After a period of use, it is easy to stick and block the steam pipe, so the activated carbon needs to be replaced frequently; in addition, the adsorption capacity of activated carbon is too strong, and the loss of rose essential oil is great; (4), during the cooking process of roses in water, they will disintegrate and become fine powder shape, it is easy to block the drainage holes at the bottom of the still, resulting in poor drainage

[0003] The problems in the above aspects make the rose essential oil extracted by existing rose essential oil and rose hydrosol extraction equipment often poor in quality, with serious loss of top fragrance and heavy color, high impurity content in the oil, and defects such as not pure fragrance; the extracted rose Pure dew has hot smell, rust smell and other peculiar smells, and the quality of the product is not high
