INDUSTRY COMPONENT

Drum Shell

Drum shell is the cylindrical outer casing of a rotary blanching machine that contains and rotates fruits/vegetables during heat treatment.

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.
