Peanuts are one of the world’s most versatile legumes, serving as a source of oil, protein, and culinary flavor. Establishing a modern peanut processing line requires careful orchestration of cleaning, shelling, roasting, blanching, and oil extraction stages. Shijiazhuang Xinlu Technology Co., Ltd. offers comprehensive peanut processing equipment that maximizes yield, safeguards product integrity, and supports a range of end-use applications.
Core Processing Stages
Intake and Pre-Cleaning: Bulk peanuts often arrive with dust, stones, and plant matter. Vibrating feeders, destoners, and aspirators work in concert to remove coarse and fine impurities, protecting downstream machinery from damage.
Shelling: Advanced shelling machines employ adjustable rollers and beaters, gently cracking peanut shells without crushing kernels. Multi-stage separation systems then segregate shells from nuts, ensuring minimal kernel damage.
Kernel Grading: Post-shelling, peanuts are graded by size and color via optical sorters. Near-infrared (NIR) sensors detect discolored or defective kernels, diverting them from the premium stream.
Roasting: Continuous belt or drum roasters apply precise heat profiles, achieving uniform roast levels for snack peanuts or peanut butter production. Temperature and dwell-time controls enable consistent flavor development.
Blanching (Optional): Hot water or steam blanching loosens the red skins before mechanical rubbers remove them. Subsequent drying units restore moisture balance for grinding or oil pressing.
Oil Extraction: Screw presses or expeller presses extract peanut oil with adjustable pressure settings. Pre-treatment of kernels—such as flaking—increases surface area and improves extraction efficiency.
Specialized Applications
Peanut Butter Production: After roasting and blanching, nuts enter grinding mills with gradual particle size reduction. Emulsion tanks integrate vegetable oils, stabilizers, and sweeteners as needed. Homogenizing units ensure creamy texture and extended shelf life.
Peanut Snack Lines: Seasoning drums and coating machines apply salt, spices, or sugar glazes uniformly. Cooling conveyors and metal detectors maintain product safety and quality.
Cold-Pressed Oil: For premium, flavor-rich peanut oil, cold pressing at controlled temperatures preserves unsaturated fatty acids and delicate aromatics. Filtration modules then clarify the oil without refining.
Automation and Data Analytics
Integrated SCADA systems capture throughput, energy consumption, and downtime metrics. Dashboards highlight trends in shelling efficiency and oil yield, guiding proactive maintenance and recipe adjustments. Remote monitoring services ensure rapid response to operational alerts.
Shijiazhuang Xinlu Technology Co., Ltd.’s expertise in peanut processing lines supports ventures ranging from boutique artisanal producers to large-scale industrial operations. By tailoring equipment configurations and process parameters, we help clients achieve consistent flavor profiles, regulatory compliance, and cost-effective productivity.
