Problems solved by technology

Spray drying, as one of the most commonly used techniques for encapsulation of fish oils and essential fatty acids, has the main disadvantage that the use of air as the drying gas at high inlet temperatures may lead to oxidation of the oil and thus reduce the shelf life of the powder

Abstract

The invention discloses a novel spray drying system for preventing grease oxidation. The system comprises a hot air system, a material supply system, a spray drying system, a separation and collectionsystem and an emptying system, wherein the hot air system is communicated with the spray drying system and is used for providing hot air for drying materials for the spray drying system; the materialsupply system is communicated with the spray drying system and used for providing raw materials for the spray drying system; the spray drying system is connected with the separation and collection system and is used for conveying nanoparticles obtained after the raw materials are atomized and dried into the separation and collection system; the separation and collection system comprises a cycloneseparator, a material cooling device and a collecting device which are connected in sequence. The device can effectively prevent the grease oxidation phenomenon of the nanoparticles in the spray drying process, is beneficial to prolonging the shelf life of the product, and can lower the loss rate in production.

Description

technical field [0001] The invention relates to a novel spray drying device for preventing grease oxidation, and belongs to the technical field of spray drying devices. Background technique [0002] Spray drying, as one of the most common nano / micro encapsulation technologies for food materials, works by dispersing the material liquid into mist droplets with an atomizer, and then heating the mist droplets with energy to dry them. A drying process to obtain a powdery product. Currently, spray drying technology has been widely used to encapsulate emulsions, enzymes, bioactive peptides and molecules, probiotics and other phenolic compounds, antioxidants, vitamins, minerals, natural food colorants, Omega-3 oils, fragrances, essential oils , antibacterial agents and many other ingredients etc. [0003] Oils rich in long-chain polyunsaturated fatty acids (PUFAs) are known to be highly oxidatively sensitive, and therefore, it is necessary to develop effective conservation strateg...
