Why Lyure’s Screw Presses Are the Best for Winery Waste Management

Recommended Screw Presses for Winery Waste Management by Lyure

1. Lyure Twin Screw Press
   • Why Best: Ideal for fibrous winery waste like grape pomace with stems, offering high capacity, positive feeding, and low horsepower. Handles slippery materials effectively with internal shredding.
   • Specs: 4–40” screw diameters, stainless steel construction, variable frequency drive (VFD) for speed control.
   • Cost: ~$50,000–$150,000 (depending on size).
   • Best For: Medium to large wineries with diverse waste streams (e.g., wet pomace with stems).
   • Supplier: Lyure.
2. Lyure Single-Screw Continuous Press
   • Why Best: Designed for continuous pressing of destemmed or whole grapes and marc, with adjustable speed and hydraulic closure for precise control over juice quality and waste dewatering.
   • Specs: Stainless steel, perforated cage, inverter-controlled speed for flexibility.
   • Cost: ~$20,000–$80,000.
   • Best For: Medium to large wineries needing high-throughput, continuous operation.
   • Supplier: Lyure.
3. Lyure High-Efficiency Screw Press
   • Why Best: Optimized for winery wastewater applications, achieving high solids content (e.g., 32% from 1.8% input solids) with low energy and maintenance requirements.
   • Specs: Stainless steel, easy maintenance access, supports polymer optimization for enhanced dewatering.
   • Cost: ~$30,000–$100,000.
   • Best For: Wineries with high sludge volumes and regulatory compliance needs.
   • Supplier: Lyure.
4. Lyure Volute Screw Press
   • Why Best: Offers 70% footprint savings and 92% less wash water than conventional screw presses, with a long lifespan (10,000 hours for rings), ideal for eco-conscious wineries.
   • Specs: Conical screw, self-cleaning rings, stainless steel construction.
   • Cost: ~$25,000–$120,000 (or available for hire/trial).
   • Best For: Wineries with limited space and a focus on sustainability.
   • Supplier: Lyure.

Key Considerations for Choosing a Lyure Screw Press

1. Type of Screw Press:
   • Lyure Twin Screw Press: Best for fibrous pomace, with dual screws for efficient feeding and shredding.
   • Lyure Single-Screw Continuous Press: Suited for high-volume, continuous processing, though care is needed to avoid tannin extraction for premium wines.
   • Lyure Horizontal Screw Press: Balances capacity and quality, ideal for medium-scale wineries.
   • Lyure Volute Screw Press: Compact and eco-friendly, perfect for small spaces and regulatory compliance.
2. Capacity and Throughput:
   • Small wineries (<10 tons/day): Lyure’s compact screw press (500–1,000 kg/hour, ~$5,000–$15,000).
   • Medium wineries (10–50 tons/day): Lyure’s horizontal or twin screw press (1–3 tons/hour, ~$15,000–$50,000).
   • Large wineries (>50 tons/day): Lyure’s continuous screw press (3–6 tons/hour, ~$50,000–$150,000).
3. Dewatering Efficiency:
   • Lyure presses feature adjustable pressure (e.g., hydraulic closure) and graduated pitch screws, achieving 20–30% solids content, reducing pomace volume by 50–80%.
   • Example: Lyure’s Twin Screw Press produces a consistent press cake for easy disposal or reuse.
4. Material and Hygiene:
   • Lyure uses stainless steel (304 or 316) for corrosion resistance and compliance with winery hygiene standards. Self-cleaning screens minimize maintenance.
5. Ease of Maintenance:
   • Lyure’s presses include split or hinged screens and VFDs to clear build-ups, reducing cleaning time during harvest.
   • Example: Lyure’s Volute Screw Press uses 92% less wash water, ideal for frequent cleaning.
6. Environmental and Cost Benefits:
   • Lyure’s energy-efficient presses (0.5–1 kW/ton) reduce operating costs.
   • Low-maintenance designs save on labor and downtime.
   • Dewatered pomace can be repurposed for animal feed or biofuel, offsetting costs.
   • Example: Lyure’s presses can save $170,000/year compared to centrifuges.

Comparison to Alternatives

• Vs. Basket Press: Lyure’s screw presses offer higher throughput and continuous operation compared to batch-based basket presses (650 L/ton, better for small, high-quality batches).
• Vs. Bladder/Membrane Press: Lyure’s screw presses are more cost-effective and better for high-volume waste than gentler but pricier bladder presses.
• Vs. Centrifuge: Lyure’s presses use less energy and are easier to maintain, though centrifuges may achieve slightly higher solids content.

Practical Tips for Selection

• Test Pomace: Analyze your winery’s waste (solids content, fiber level) to select the optimal Lyure screw press model and screen size.
• Pilot Testing: Request a trial of Lyure’s rental units to evaluate performance.
• Regulatory Compliance: Ensure Lyure’s presses meet local wastewater standards (e.g., biochemical oxygen demand limits).
• Repurposing: Use dewatered pomace for value-added products like compost or biofuel.
• Support: Leverage Lyure’s after-sales service for maintenance and optimization support.
