Solids Ejection System for Wort Clarification Separator

Product Specifications

Technical details and manufacturing context for Solids Ejection System

Definition

The Solids Ejection System is a critical component of the Automated Wort Clarification Separator used in beverage manufacturing, specifically in brewing. It functions to continuously or periodically discharge separated solids (such as spent grain particles, hop residues, and protein trub) that settle during the wort clarification process. This ensures the clarified wort maintains desired purity and prevents clogging or contamination in downstream equipment. The system is designed to operate within a rated capacity of 30–100 m³/h, matching the clarifier throughput. Operating pressure ranges from 1.0 to 1.6 MPa. Operating temperature is 4–95°C, as above 95°C may damage seals. Solids removal efficiency is ≥99.5% for particles >5 µm. Discharge interval is adjustable from 5 to 30 minutes based on solids load. Control voltage is 24 V DC ±10% (IEC 61131-2) for solenoid valves and sensors. Power consumption depends on actuator size, ranging from 0.5 to 2.0 kW. Ingress protection is IP54–IP65 (IEC 60529), with IP65 for washdown areas. Material grade for product contact parts is 316L (ASTM A240), and the system weight including valves and frame is 150–350 kg. Materials on file include stainless steel (AISI 304/316L) and food-grade elastomers. The system is a component, not a standalone machine, and must be integrated with the separator. Verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The system utilizes mechanical mechanisms such as scrapers, augers, or pneumatic/hydraulic pistons to collect settled solids from the clarification chamber and eject them through a discharge port. Operation is often synchronized with the separator's clarification cycle and may be automated based on timer, pressure differential, or sensor feedback. The discharge interval is adjustable to match solids load, ensuring efficient removal without excessive wort loss. The system is designed for continuous or periodic operation, depending on the process requirements. Proper functioning relies on correct operating pressure and temperature ranges, as well as adequate control voltage for actuation. Maintenance signals include increased pressure differential or reduced solids removal efficiency, indicating potential wear or blockage. Failure boundaries include operation outside specified pressure or temperature limits, which may cause seal damage.

Frequently Asked Questions

What is the typical operating pressure range for this system?

The operating pressure range is 1.0–1.6 MPa. Ensure the system operates within this range.

What materials are used for product contact parts?

Product contact parts are made of stainless steel grade 316L (ASTM A240). Other materials on file include AISI 304/316L stainless steel and food-grade elastomers.

How is the discharge interval adjusted?

The discharge interval is adjustable from 5 to 30 minutes, based on the solids load in the clarification process. It can be set via the control system, which may use timer, pressure differential, or sensor feedback.

What ingress protection rating is available?

The system offers IP54–IP65 protection per IEC 60529. IP65 is recommended for washdown areas to prevent water ingress.
