Grain Grinding Machines (grain mills/crushers) are core equipment in the food processing industry, widely used for precision processing of various grains, condiments, and functional foods. Below are their main applications and technical features:

1. Staple Food Processing

(1) Flour & Rice Powder Production

◆ Applications:

- Wheat grinding (high/low gluten flour)

- Rice milling (rice flour, rice cake ingredients)

- Multigrain blended flour (oat + buckwheat composite)

◆ Technical Requirements:

- Multi-stage grinding (crushing → fine milling → classification)

- Low-temperature processing (<45°C to preserve B vitamins)

◆ Representative Equipment:

- Roller mills (capacity: 5-20 tons/hour)

- Air-classifying mills (ultra-fine rice powder >300 mesh)

(2) Breakfast Cereal Processing

◆ Applications:

- Cornflake/oatmeal base material crushing

- Instant cereal powder (hot water soluble)

◆ Innovative Process:

- Expanded micro-grinding (improves solubility)

2. Condiment & Ingredient Production

(1) Spice Processing

◆ Applications:

- Superfine grinding of chili, pepper, cinnamon (200-500 mesh)

- Blended seasoning grinding

◆ Technical Challenges:

- Preventing essential oil loss (low-temperature closed system)

- Avoiding cross-contamination (food-grade stainless steel)

(2) Sugar & Salt Refining

◆ Applications:

Ultra-fine grinding of rock sugar/brown sugar (for baking)

Homogenization of low-sodium salt particles

◆ Special Design:

Anti-caking jet milling (with silica additive)

3. Functional Food Ingredient Processing

(1) Plant Protein Powder

◆ Applications:

- Soy protein isolate (80-100 mesh)

- Pea protein micronization (improves solubility)

◆ Key Process:

- Wet ultrafine grinding of defatted soybean meal

(2) Dietary Fiber Extraction

◆ Applications:

- Precise classification of oat β-glucan

- Fruit pomace (apple/orange peel) recycling

◆ Equipment Innovation:

- Enzymatic-assisted grinding technology

4. Snack Food Manufacturing

(1) Nut Butters & Spreads

◆ Applications:

- Colloid mill refining for peanut/almond butter

- Primary crushing of cocoa beans (chocolate原料)

◆ Fineness Control:

Particle size ≤20μm (smooth texture)

(2) Crisps & Puffed Foods

◆ Applications:

- Whole potato powder (for chips)

- Extruded corn flour

◆ Process Integration:

- Crushing → mixing → extrusion production line

5. Special Food Processing

(1) Infant Complementary Food

◆ Applications:

- Organic rice cereal (additive-free fine grinding)

- Fruit/vegetable powder (freeze-dried + low-temperature milling)

◆ Safety Requirements:

- GMP-compliant, 316 stainless steel materials

(2) Medical Nutrition Products

◆ Applications:

- Hypoallergenic rice flour (enzyme-treated)

- Tube-feeding nutrition powder (ultra-homogenized)

Technical Standards for Food-Grade Grinding

Industry Trends

Smart Technology:

- Real-time particle monitoring + auto-adjustment

Customization:

- Modular design (quick-change discs/sieves)

Energy Efficiency:

- High-frequency vibration milling (40% less energy)

Conclusion

From traditional flour to functional foods, Grain Grinding Machines are driving the food processing industry toward precision and nutrition. Future developments will focus on:
Nutrient retention (e.g., cryogenic grinding)
Clean label (reducing additives)
Flexible production (small-batch multi-variety switching)
