🧱 Solid or Concentrated Industrial Dishwasher Detergents – Production, Formulation and Properties
Overview:
Solid or concentrated industrial dishwasher detergents are next-generation cleaning formulations designed for high-efficiency and sustainable dishwashing systems.
Unlike traditional liquids or powders, these detergents are produced in solid block or capsule form, providing precise automatic dosing, minimal waste, and enhanced operator safety.
They are widely used in restaurants, hotels, hospitals, catering centers, and institutional kitchens, where high-volume dishwashing requires consistency, hygiene, and cost efficiency.
Their concentrated nature means less packaging, reduced transportation costs, and lower environmental impact, making them an ideal choice for modern industrial cleaning operations.
Solid detergents typically contain high levels of alkaline builders, chelating agents, low-foam surfactants, and corrosion inhibitors, compacted into a stable, water-soluble matrix.
When used in automatic dosing systems, they dissolve gradually, maintaining the correct concentration throughout the washing cycle.
Production and Formulation:
The production of solid or concentrated industrial dishwasher detergents requires specialized processing equipment that ensures chemical homogeneity, moisture resistance, and controlled dissolution.
Typical formulation components include:
-
Alkaline Builders: Sodium hydroxide, sodium metasilicate, and carbonate for pH control and heavy-duty cleaning.
-
Chelating Agents: MGDA, GLDA, or EDTA to prevent scaling and water hardness interference.
-
Low-Foam Surfactants: Nonionic surfactants (ethoxylated alcohols or APGs) for grease and soil removal.
-
Corrosion Inhibitors: Silicates or phosphonates for stainless steel and machine protection.
-
Binders and Solidifiers: Polyethylene glycol (PEG), urea, or sodium sulfate to create a stable solid structure.
-
Stabilizers: Prevent degradation of sensitive components such as enzymes or oxidizing agents.
-
Optional Additives: Mild oxidizers or defoamers for enhanced performance.
Production Process:
-
Dry Blending: Builders, surfactants, and additives are mixed to achieve uniform composition.
-
Melting / Fusion: The blend is heated (40–70°C) and combined with binders for solidification.
-
Molding or Extrusion: The mixture is formed into blocks, capsules, or tablets.
-
Cooling and Packaging: Solid blocks are cooled, wrapped in moisture-resistant film, and sealed for safe storage.
The resulting product is highly concentrated, chemically stable, and easy to handle, ideal for automatic dishwashing systems equipped with solid detergent dispensers.
Properties:
-
Highly Concentrated Formula: Delivers maximum cleaning performance with minimal usage.
-
Controlled Dissolution: Gradual release ensures consistent detergent concentration.
-
High Alkalinity (pH 11–13): Effective for degreasing and soil removal.
-
Low-Foam System: Prevents mechanical interference in dishwashing equipment.
-
Scale and Spot Control: Chelating agents maintain water softness and clarity.
-
Corrosion Inhibition: Protects metal surfaces and machine parts.
-
Thermal and Storage Stability: Resistant to moisture and temperature variations.
-
Eco-Efficient Design: Reduces plastic packaging and transportation footprint.
-
Operator Safety: No spillage or direct contact with corrosive liquids.
-
Automatic Dosing Compatibility: Ensures consistent concentration and cost control.
Summary:
Solid or concentrated industrial dishwasher detergents represent the evolution of professional dishwashing chemistry — delivering high performance, safety, and sustainability.
Their compact, stable form allows automated dosing, waste reduction, and long-term cost efficiency while maintaining excellent cleaning power.
By integrating strong alkalinity, water softening, and corrosion protection, these solid formulations ensure spotless, hygienic, and eco-responsible cleaning across all industrial dishwashing applications.
