Preparation process and device of vitamin D3 microcapsule powder

Abstract

The invention relates to a preparation process and a preparation device of vitamin D3 microcapsule powder. In the preparation process, VD3 oil, sunflower seed oil or corn oil, medicinal starch, maltodextrin, modified starch, white sugar, calcium phosphate and 2,6-di-t-buty-4-methylphenol (BHT) are used as main raw materials. The preparation process and the preparation device are reasonably improved and optimized, the production time is greatly shortened and the whole production process is controlled; through layer-by-layer drying and step-by-step recycling, the prepared vitamin D3 microcapsule powder has smooth and flat surface, and the safety, the fluidity, the mouth feel and the water solubility of the vitamin D3 microcapsule powder are greatly improved; the waste of resources is reduced, the continuous large-scale production is implemented, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of production of vitamin D3 microcapsule powder, in particular to a preparation process and device of vitamin D3 microcapsule powder. Background technique [0002] In the production process of vitamin D3 microcapsule powder, spray drying and microcapsule coating are the two most critical technical steps, which directly affect the safety, fluidity, taste and water solubility of the product. The microcapsule wall material refers to the shell material used to coat the core material during microencapsulation, also known as encapsulation material, capsule material, and shell material. Most of the materials that can be used as microcapsule wall materials are inert polymeric natural polymers, semi-synthetic polymers and synthetic polymer materials. Among them, natural polymer materials have the advantages of non-toxicity, good film-forming properties, and good stability, and are widely used, but their mechanical s...

AI Technical Summary

Problems solved by technology

For the selection of microcapsule coating materials, leather gelatin or animal gelatin is mostly used in traditional techniques. Although coating can also be completed to a certain extent, and the cost is relatively low, leather gelatin and animal gelatin often contain more Harmful substances such as cadmium, arsenic, and aflatoxin have been unable to meet the current product safety and hygiene standards

In addition, gelatin-coated products have poor fluidity and poor water solubility, especially not conducive to cold water diffusion and poor release, which greatly affects the use effect of the product

[0003] In addition, granulation spray is a commonly used technical method. Spray granulation inevitably involves product coating. The quality of the coating effect mainly depends on the coating material and drying technology. How to disperse the material particles as homogeneously as possible , complete heat and mass transfer in an instant, avoid material sticking or sticking to the wall, and complete drying is a technical problem faced in this field. The combination of spraying and drying technology in the traditional process is relatively simple, resulting in product coating. The stability is poor, and the product particles are not uniform enough

At present, most of the production equipment of vitamin D3 microcapsule powder is unreasonable due to the unreasonable structural design, so that the vitamin D3 microcapsule powder cannot be fully dried during the production process, resulting in defects such as uneven particle size and sticky particles, which affect the product. The quality and efficiency of continuous production, it is difficult to achieve effective recycling of coating components scattered in granulation, sieving, drying and other processes, resulting in a large waste of resources
