Against the backdrop of upgrading consumer health trends, the functional food industry is experiencing explosive growth, and the level of sophisticated processing of raw materials directly determines a product's efficacy, taste, and market competitiveness. Vertical milling machines, with their core advantages of precision, intelligence, and minimal material loss, have become essential equipment in the raw material processing stage for functional foods. Widely applied In the processing of raw materials such as dietary fiber, plant polyphenols, probiotic carriers, and functional starches.

The biggest difference between functional food ingredients and ordinary food ingredients lies in the fact that functional ingredients—such as bioactive peptides, flavonoids, dietary fibers, and more—require extremely precise processing techniques to maintain their efficacy, solubility, and bioavailability. The vertical milling machine, by precisely controlling grinding temperature, particle size distribution, and hygiene standards, perfectly meets the needs of functional food ingredients. The processing requirements of "low temperature, precision, efficiency, and cleanliness" lay a high-quality raw material foundation for subsequent processes such as extraction, mixing, and molding.

Dietary fibers (such as inulin, konjac glucomannan, and wheat bran fiber) are commonly found in functional foods. Of the However, the processing challenge lies in how to preserve the intact structure of the fibers during grinding while simultaneously enhancing their water solubility and dispersibility. The vertical milling machine achieves this by adjusting Stirring shaft Rotational speed can grind dietary fiber materials down to Micro- and nanoscale Ultra-fine granularity with uniform particle size distribution.

Plant polyphenols—such as tea polyphenols, grape seed extract, and curcumin—are the core functional ingredients in health foods. However, their raw materials (tea leaves, grape seeds, turmeric rhizomes) are typically hard and highly resilient, and polyphenol compounds tend to degrade easily under high temperatures and intense light. Taking grape seed processing as an example, a vertical milling machine employs a segmented process involving primary crushing followed by secondary grinding, effectively avoiding the issue of coarse particles remaining unground while fine particles are over-ground—a common problem in traditional single-stage milling. As a result, the ultra-fine ground grape seed powder exhibits a significantly increased specific surface area. Not The subsequent ethanol extraction lays the groundwork, providing technical support for the large-scale production of polyphenol-based functional foods.
