Preparation method of microcapsule plant essential oil

Abstract

The invention relates to a preparation method of microcapsule plant essential oil, which uses dispersing and stirring equipment. The dispersing and stirring equipment comprises a stirring tank, a topcover and a dispersing device, the specific method for preparing the microcapsule plant essential oil by using the dispersing and stirring equipment comprises the following steps of: cleaning the rawmaterials, distilling, extracting, stirring, spray-drying and packaging. The top cover is installed at the top end of the stirring tank, a dispersing device is installed between the inner wall of thestirring tank and the lower end of the top cover, annular grooves are evenly formed in the inner wall of the stirring tank from top to bottom, the dispersing device comprises a rotating motor, a driving rod, a driven rod, a pushing rod, a stirring frame and a supporting sliding rail, and the stirring frame comprises an installation sleeve, protrusions, main stirring rods, auxiliary stirring rods and racks. The mixed liquid in the stirring tank is stirred in multiple directions through the dispersing device until an emulsion is formed, the stirring frame can reciprocate up and down in the stirring process, the stirring range is enlarged, and the emulsifying speed is increased.

Description

technical field [0001] The invention relates to the field of flavor and fragrance industry, in particular to a preparation method of microcapsule plant essential oil. Background technique [0002] Plant essential oils embedded with microcapsule technology can prevent the loss and deterioration of essential oils during storage, and at the same time release slowly during the use stage, and can greatly expand the application fields of essential oils, so they are worthy of widespread promotion. [0003] The preparation of microcapsules is generally divided into chemical methods, physical chemical methods and physical methods in principle, but the principles of chemical methods and physical chemical methods are more or less related to the chemical reactions of substances, and it is difficult to ensure the integrity of the embedded essential oils. The aroma does not change, and the preparation of microencapsulated essential oils by physical methods is very suitable. Among them, th...

AI Technical Summary

Problems solved by technology

However, there are still some problems in the process of emulsification and stirring at present: a. In the case of misoperation, the stirring equipment will start in advance, and the stirring blades rotating at high speed may cut the staff, and the safety during the work is low; b. .During the stirring process, since the installation position of the stirring blade is fixed, only a certain range of mixed liquid can be stirred, the stirring efficiency is the lowest, and it is difficult to ensure the uniformity of liquid dispersion, which affects the emulsification effect
