Extracting and purifying process and apparatus of haw nuclear distilling oil

Abstract

The present invention provides purification process of distilled haw kernel oil and the rotary horizontal dry distilling furnace therefor. Haw kernel is dry distilled in a rotary horizontal dry distilling furnace and the outflow dry distilled fluid is purified through filtering in a filter to eliminate solid impurity, adsorption in a adsorbing column with 70-90 mesh haw kernel carbon black, adsorption in a adsorbing column with 140-160 mesh haw kernel carbon black, deodorizing and decolorizing. The rotary horizontal dry distilling furnace includes a furnace body, a nitrogen inlet pipe, a lead-out pipe, a condensator and a vapor-liquid separator. The present invention can eliminate residual wood tar from haw kernel dry distilled fluid effectively.

Description

field of invention [0001] The invention belongs to the technical field of hawthorn core processing, and in particular relates to a method and a device for extracting and purifying hawthorn core dry distillation oil from the hawthorn core. Background of the invention [0002] Hawthorn is a kind of sour fruit that people like. It can be made into various foods to meet the needs of different tastes. Hawthorn core distilled oil is a viscous liquid extracted from the fruit core of hawthorn after eating. It has unexpected antibacterial, bactericidal and disinfection effects, such as it has relatively strong effects on Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, etc. Strong antibacterial effect, therefore, using hawthorn nuclear distillate oil as raw material to make in vitro skin fungicide or bactericidal soap can not only remove dirt on the skin and decompose oily crusts, but also kill bacteria lurking in the skin tissue. Since hawthorn distilled oil is a pu...

AI Technical Summary

Problems solved by technology

[0003] The hawthorn distilled oil produced from the hawthorn kernel by dry distillation is a black viscous liquid containing carbonized hawthorn kernel particles, so it has a burnt odor, which limits the application and development of the hawthorn distilled oil. For example, in the Chinese patent application CN1060109A, it is mentioned that the core of Shanlihong is dry-distilled to obtain a liquid, and then evaporated and concentrated into a black viscous liquid with a burning smell. Therefore, the dry-distilled liquid involved in this patent application is limited to making solids and liquids. medicated soap

Chinese patent application CN1182538A relates to a method for producing detoxifying and bactericidal agents from hawthorn distilled oil. It collects liquid from two-step dry distillation temperatures of 90-110°C and 200-300°C. The process and device used are all simple dry distillation. Wood burnt odor is also unavoidable

A recent patent application CN1366024A (inventor Shi Yi), the technology of extracting disinfectant by dry distillation of hawthorn core has all been improved in process and equipment, and has achieved certain results, but the obtained hawthorn core distillation oil still has Wood burnt smell, application in medicine disinfection, cosmetics preservation and food preservation is still restricted
