Rotary Fruit and Vegetable Blanching Drum

Product Specifications

Technical details and manufacturing context for Rotary Fruit and Vegetable Blanching Drum

Definition

A rotary blanching drum is a critical component in fruit and vegetable processing lines that ensures uniform heat treatment through continuous rotation. This component facilitates enzyme inactivation, color retention, and microbial reduction while maintaining product texture. It integrates into larger blanching systems where precise temperature control and consistent product movement are essential. Industrial manufacturers supply these drums to food processing equipment OEMs for integration into complete processing lines. The drum is typically constructed from stainless steel 316L or food-grade polypropylene, with material grade options including 304 and 316L per ASTM A240. Key parameters include drum diameter (800–2000 mm), drum length (2000–6000 mm), rotation speed (2–12 RPM), material thickness (2–5 mm), maximum load capacity (500–3000 kg), operating temperature range (0–100 °C), operating pressure (0.1–0.4 MPa), drive power (1.5–7.5 kW), electrical supply (380–480 V AC, three-phase, 50/60 Hz per IEC 60038), ingress protection rating (IP54–IP65 per IEC 60529), and weight (1500–5000 kg). These values are reference ranges and must be confirmed for the specific model and application. The drum is designed for continuous operation, with rotation ensuring even heat distribution and preventing clumping. It is suitable for use in hot water or steam blanching processes. For procurement, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The drum rotates continuously, tumbling produce through hot water or steam. This ensures even heat distribution across all product surfaces, preventing clumping and promoting uniform enzyme inactivation. The rotation speed is adjustable within 2–12 RPM to suit different product types and processing requirements. The drum's internal flights or baffles (if present) aid in gentle product movement. The heating medium (water or steam) is maintained at the required temperature, typically up to 100 °C, with pressure up to 0.4 MPa. The continuous tumbling action also helps in reducing processing time and improving throughput. The design allows for precise control of residence time and temperature, which are critical for achieving consistent product quality.
