Solving a Persistent Culinary Bottleneck


Traditionally, the application of delicate finishes—such as chocolate, cocoa butter, velvet coating,

and egg wash—on pastries has been a manual, labor-intensive, and often messy process.

Existing solutions in the market were frequently adapted from non-food industrial applications,

leading to significant sanitation difficulties, cross-contamination risks, and inconsistent application quality.


Recognizing this critical need for specialiation, CoatTech leveraged its deep expertise in precision coating and environmental control to develop a superior,

sanitary solution.


The new booth is designed not just to spray, but to manage the entire coating lifecycle with efficiency and hygiene at the forefront.

Innovation in Hygiene and Efficiency


The new CoatTech Spray Booth sets a new industry standard through several key innovations:


1.100% Food-Grade Construction: The entire internal structure and contact surfaces are crafted from premium SUS304 stainless steel, ensuring compliance with the strictest international food safety and hygiene regulations (HACCP).


2.Automated Clean-In-Place (CIP) System: This is the centerpiece of the innovation. Understanding that chocolate and cocoa butter solidify quickly and are notoriously difficult to clean, the booth features a fully automated, integrated hot-water CIP system. High-pressure rotary spray balls ensure thorough cleaning of all internal walls, corners, and the water curtain trough without requiring manual intervention, dramatically reducing downtime and guaranteeing sanitation.


3.Superior Airflow & Overspray Management: The booth features a robust, uniform exhaust system paired with an active water curtain, effectively capturing overspray and airborne particulate, thereby protecting the product quality and maintaining a clean, safe working environment for staff.


4.Adaptability and Scale: Available in large walk-in configurations (3x3m or 4x3m) with a central stainless steel table, the booth enables high-volume, simultaneous spraying of trays of products, enhancing production throughput without compromising on consistency.
