Horizontal Spiral Drum Washer for Fur Leather

Product Overview

The Horizontal Spiral Drum Washer for Fur Leather sets a new standard in leather processing equipment, combining gentle material handling with exceptional cleaning efficiency. Designed specifically for fur and leather substrates, this industrial washer features a unique cascade drum design with optimized perforation patterns that deliver 500G water extraction while preventing fiber damage or hair loss. The horizontal configuration with spiral flighting ensures continuous, uniform processing of hides and furs, reducing manual handling and improving batch consistency. Constructed with 304 stainless steel frames and 316L stainless steel contact surfaces, the washer meets the strict hygiene requirements of modern leather production facilities. With processing capacities ranging from 50 to 500 kg/batch and adjustable cycle times (10-45 minutes), it accommodates various leather types while achieving 99% impurity removal efficiency – critical for high-quality tanning and finishing results.

Product Features

Innovative Drum Design

The patented cascade drum features:

Specialized bulge geometry that increases water extraction by 30% compared to conventional drums

40% more perforations per unit surface area for enhanced liquid exchange

Smooth, rounded edges to prevent hide tearing or fur matting

Spiral flighting with variable pitch to control material residence time

Precision Cleaning System

Multi-stage spray manifolds with adjustable pressure (0.2-0.6MPa)

Temperature-controlled wash zones (30-60°C) with ±2°C accuracy

Chemical injection system with proportional dosing (0.5-5% concentration)

Counter-current flow design reducing water consumption by 40%

Gentle Material Handling

Variable drum rotation speed (3-12 rpm) to match material sensitivity

Soft-start/stop functionality to prevent sudden material movement

Automatic load balancing for consistent processing

Programmable cycle profiles for different leather/fur types

Durability & Hygiene

Fully welded stainless steel construction with IP65-rated electrical components

Sloped surfaces for complete drainage and easy cleaning

CIP-compatible design with rotary spray balls

Corrosion-resistant hardware suitable for alkaline cleaning solutions

Applications

Fur Processing

Raw fur cleaning (removing dirt, blood, and soluble proteins)

Wool-on hide preparation for sheepskin and lambskin

Fur dyeing preparation (uniform moisture conditioning)

De-greasing of fatty furs (beaver, otter) prior to tanning

Leather Production

Beamhouse operations (soaking and liming assistance)

Deliming and bating preparation

Post-tanning washing (removing excess tannins)

Finishing pre-treatment (uniform moisture adjustment)

The washer's ability to reduce final moisture content to 15-20% significantly shortens drying times in subsequent processing stages, increasing overall production throughput by up to 25%.

FAQ

How does it prevent fur damage?

The drum's specially designed flights and controlled rotation speed (3-6 rpm for delicate furs) ensure minimal fiber agitation while maintaining effective cleaning. The rounded perforation edges eliminate snagging points.

What water consumption rates can be expected?

The counter-current system uses 8-12 liters per kg of material depending on soil load, significantly lower than the 15-20 liters/kg consumed by conventional washers.

Can it handle different leather types?

Yes, programmable cycle profiles allow optimization for:

Delicate skins (sheepskin, goatskin)

Heavy hides (cowhide, buffalo)

Exotic leathers (crocodile, ostrich)

Wool-on products requiring special care

What maintenance is required?

Weekly inspection of spray nozzles for clogging, monthly lubrication of bearings, and quarterly inspection of drum perforations for wear. The system includes diagnostic software to alert operators to potential issues.

Is it compatible with cleaning chemicals?

The 316L stainless steel construction is compatible with all standard leather processing chemicals including acids, alkalis, and surfactants. Chemical dosing systems are material-compatible with corrosive agents.
