[0026] After mixing the ingredients described in Table 1 at 60°C, homogenize under a homogeneous pressure of 70MPa to form a uniform emulsion, then keep warm at 90°C for 3 minutes, and sterilize; then use a high-pressure pump to spray the emulsion through an atomizing spray gun Turn into liquid droplets and spray into the preheated boiling drying bed. The atomization pressure of the pressure atomization is 1-2MPa. The bottom of the boiling drying bed is pre-installed with 100Kg lactose. The drops meet the lactose in boiling fluidized state, and are wrapped and dried by lactose. At the same time, lactose is continuously added to the boiling drying bed, and the dried material is continuously sucked out from the boiling drying bed and sieved to obtain arachidonic acid. Oil microencapsulation products. The separated lactose is sent back to the fluidized drying bed through the conveying system for reuse.

Under the action of hot air at 40°C, the atomized droplets meet the powder embedding material in a boiling fluidized state, and are wrapped and dried by the powder embedding material. At the same time, vacuum feeding equipment is used to continuously replenish lactose and tricalcium phosphate powder into the fluidized drying bed, and continuously suck the materials from the fluidized drying bed into the fluidized bed for...

[0036] The ingredients described in Table 3 were mixed and emulsified at 60°C, homogenized under a homogeneous pressure of 80MPa to form a uniform emulsion, and then kept at 90°C for 3min and sterilized; The flow rate is sent to the centrifugal spray drying tower with a built-in fluidized bed for centrifugal atomization. The atomization speed is 2000-3500r / min. The inlet air temperature of the tower is 180°C. At the same time, lactose is added to the spray drying tower at a speed of 65kg / h, and the material is continuously discharged from the outlet of the built-in fluidized bed at a speed of 100kg / h, and is sieved through a 120-mesh sieve to separate Arachidonic acid oil microcapsules, the separated lactose is returned to the drying tower through the conveying system for reuse.

Abstract

The invention relates to a microcapsule preparation method and a product thereof. The microcapsule preparation method is characterized by comprising the following steps that: the powder embedding material is put into a drying device in advance, and is kept in a suspension or boiling fluidized state under hot blast, and is lactose or lactose composite powder; and meanwhile, the emulsified liquid which is prepared from core materials, emulsifier and water is atomized into liquid drop to be sprayed into the drying device, the atomized liquid drop is contacted with the powder embedding material which is in the suspension or boiling fluidized state and is wrapped by the powder embedding material, meanwhile, particles are formed by the drying of the hot blast, and the microcapsule product is obtained after separation. The method adopts the lactose or lactose composite powder as the powder embedding material, the prepared microcapsule takes the single particle as the main part, and the particles are more regular in shapes, are not adhered with one another, have better stability, better liquidity and higher safety at the same time.

Description

technical field [0001] The invention relates to a preparation method of microcapsules and products thereof. Background technique [0002] Microcapsule technology refers to the technology of using film-forming materials to encapsulate solids, liquids or gases in them to form tiny containers with a diameter of tens of microns to thousands of microns. The material loaded inside the microcapsule is called the core material (or capsule core material) , The wall membrane of the external capsule is called wall material (or cyst material). [0003] Food nutritional fortification can ensure that people can obtain comprehensive and reasonable nutrition at various stages of growth and development and under various working conditions, meet the normal needs of human physiology, life and work, and maintain and improve human health. However, some fortifiers are unstable, such as vitamins, polyunsaturated fatty acid oils, amino acids, etc., which are easily oxidized and lost when exposed t...
