Complete Guide to Washing Reusable Drums, Pails, Buckets and IBC Containers
Reusable industrial containers are widely used throughout the global food and beverage industry for transporting and storing bulk ingredients such as edible oils, liquid sugars, syrups, sauces, flavourings and dairy products.
Containers including steel drums, plastic drums, pails, buckets and intermediate bulk containers (IBCs) are essential for modern food manufacturing and ingredient logistics.
As manufacturers increasingly adopt reusable packaging systems, reliable cleaning processes are essential to ensure hygiene, prevent contamination and maintain regulatory compliance.
Industrial container washing systems supplied by Rotajet Systems Ltd are widely used by manufacturers looking to implement reliable drum washing, pail washing and IBC washing processes within food production environments.
This guide explains how industrial container washing works and how automated washing technology allows manufacturers to safely reuse drums, pails and IBC containers while maintaining strict hygiene standards.
Why Container Washing Is Critical in Food Manufacturing
Food manufacturing operates under strict hygiene regulations designed to protect product quality and consumer safety.
Industry standards promoted by the European Hygienic Engineering & Design Group emphasise hygienic equipment design and proper cleaning procedures throughout food processing operations.
International food safety frameworks developed by the Codex Alimentarius Commission also require manufacturers to control contamination risks within production environments.
Reusable containers must therefore be cleaned thoroughly between production batches.
Improperly cleaned containers may lead to:
- allergen cross contamination
- microbial growth and spoilage
- product quality failures
- regulatory non-compliance
- costly product recalls
Modern automated washing systems such as those designed by Rotajet ensure containers are cleaned consistently using controlled wash cycles rather than labour-intensive manual cleaning methods.

Containers Used in the Food Industry
Food ingredients are transported and stored in a wide range of reusable containers depending on batch size, product type and supply chain logistics.
Steel Drums
Steel drums are widely used for transporting food ingredients including edible oils, flavourings and concentrates.
Industrial drum washing machines are designed to clean both the internal and external surfaces of these containers.

Plastic Drums
Plastic drums are commonly used for products such as syrups, sauces and liquid food ingredients.
Because many food products are viscous or sticky, plastic containers often require heated washing systems combined with detergents to remove residues effectively.
Industrial washing equipment supplied by Rotajet includes drum washing machines designed for hygienic food industry applications.
Pails and Buckets
Pails and buckets are used throughout the food industry for transporting smaller quantities of ingredients such as additives, colourings and flavourings.
Automated pail washing machines allow large volumes of containers to be cleaned efficiently while maintaining hygienic conditions.

Intermediate Bulk Containers (IBCs)
Intermediate Bulk Containers are widely used for transporting bulk food ingredients.
Typical food industry applications include:
- liquid sugar
- edible oils
- beverage concentrates
- dairy ingredients
IBCs typically hold 600–1000 litres and require specialised washing equipment capable of cleaning both the internal container and external cage.

Challenges When Cleaning Food Containers
Food ingredients often create complex cleaning challenges that require specialised washing equipment.
Sticky Residues
Products such as syrups, sugars and sauces adhere strongly to container surfaces.
Oils and Fats
Greasy residues require heated wash water and alkaline detergents to dissolve effectively.
Allergen Control
Containers used for allergenic ingredients must be completely cleaned before reuse.
Microbial Growth
Food residues can support bacterial growth if containers are not properly cleaned and dried.
Because of these challenges, automated washing technology such as Rotajet container washing systems is increasingly used across food manufacturing facilities.
Industrial Container Washing Process
Industrial washing machines use controlled cleaning cycles designed to remove residues and sanitise reusable containers.
Typical washing stages include:
1 Product Drain
Residual product is drained from the container before washing begins.
2 Pre-Wash
High pressure water removes loose residues and debris.
3 Heated Detergent Wash
Food-grade detergents combined with heated water dissolve oils, fats and sugars.
4 High Pressure Internal Cleaning
Rotary spray heads deliver pressurised water to all internal surfaces.
5 Fresh Water Rinse
A final rinse removes cleaning chemicals.
6 Container Drying
Air knives or vacuum drying systems remove moisture before reuse.
Modern automated washing systems such as those engineered by Rotajet Systems Ltd provide repeatable cleaning performance across high-volume food production environments.
