Component Specifications

Definition
The drum shell is a critical structural component in rotary fruit and vegetable blanching systems, consisting of a cylindrical stainless steel enclosure with perforated walls. It rotates on a horizontal axis, facilitating uniform exposure of produce to steam or hot water while allowing drainage of processing liquids. The shell incorporates mounting flanges for drive mechanisms, temperature sensors, and safety interlocks.
Working Principle
The drum shell rotates via an external drive system, creating a tumbling action that ensures even blanching. Heat transfer occurs through the shell's material and perforations, with the cylindrical design optimizing thermal distribution and product flow.
Materials
AISI 304 or 316L stainless steel, thickness 2-4mm, food-grade certified, with corrosion-resistant properties for wet/high-temperature environments.
Technical Parameters
  • Length 2000-5000mm
  • Diameter 800-1500mm
  • Load Capacity 200-1000kg
  • Rotation Speed 5-15 RPM
  • Max Temperature 120°C
  • Perforation Size 3-8mm diameter
Standards
ISO 14159, DIN 11850
