Proportioning system, mixer, and continuous former in one compact integrated system.
Our DRC-40 Protein Bar Extruding Line is a fully automatic, compact solution for protein bar production. It includes precise proportioning, uniform mixing, and continuous extruding. This system is suitable for protein powders, grains, nuts, dried fruits, and binders. The integrated design from raw material feeding to formed bars significantly reduces manual handling and improves production efficiency.
This production line is purpose-built for:
Protein bar factories producing high-protein snack bars
Sports nutrition manufacturers with bar product lines
Health food companies requiring consistent bar quality
Functional food producers adding protein and nutritional ingredients
Export-oriented food businesses supplying protein bars to global markets
Its compact design ensures reliable output, consistent bar quality, and space-saving layout—key factors for competitive protein bar production.
This Protein Bar Extruding Line follows a mature, industrial process designed for stable output, consistent product quality, and efficient compact production.
Proportioning → Mixing → Continuous Extruding → Cutting → Packing
The proportioning system precisely weighs protein powders, grains, nuts, and binders according to recipe. The mixer then blends all ingredients uniformly. This ensures consistent quality and nutritional content for every batch.
Mixed material is fed into the continuous former. It extrudes the mixture into uniform bar shapes. Consistent size, precise weight, and firm texture for every single bar. Quick-change dies allow fast product switchovers.
