Safety valves for Coffee Machines
Safety and Reliability for the Coffee Machine Industry
Safety valves designed to ensure maximum control and regulatory compliance.
Industry Requirements
Copper Products Compliant with MOCA (D.E. 1935/2004)
The use of copper alloys in industrial coffee machines addresses specific needs in the industry, including:
- Thermal conductivity: Copper has excellent heat transfer capabilities, crucial for components such as boilers and heat exchangers, ensuring optimal coffee extraction.
- Production costs: Compared to other materials like stainless steel, copper is more affordable, allowing manufacturers to control costs without compromising performance.
- Ease of processing: Copper is easy to work with, offering greater flexibility in designing and producing complex components for coffee machines.
However, this choice also requires ensuring compliance with regulations, such as MOCA certification, to avoid contamination in the coffee and ensure the safety of the final product.
Where Are Safety Valves Located?
In the coffee machine industry, safety valves (PSV, Pressure Safety Valves) are essential for protecting vessels, such as boilers or pressure tanks in coffee machines, from overpressure that could cause structural damage or pose a danger to the operator. Coffee machines, particularly professional ones, operate with a system that heats water under pressure to extract coffee through the espresso method. During the heating process, the water is brought to very high temperatures, and any accumulation of steam and internal pressure is carefully monitored. If the pressure exceeds the safety limit, the PSV activates automatically, allowing the excess steam to escape in a controlled manner.
Safety valves are typically installed on the boiler or steam storage vessel, and it is common to find them at strategic points in the system to ensure that the entire system is protected. Installing a PSV in coffee machines is critical to prevent explosions or damage to the machine components caused by excessive pressure, while ensuring safe and optimal operation. Additionally, the use of safety valves ensures that the system complies with safety regulations and necessary certifications, protecting both the integrity of the machinery and the safety of the operators.
Challenges and Critical Issues in the Industry
Certified and Economical Materials for Maximum Food Safety
The MOCA certification (Materials and Objects in Contact with Food) is particularly critical for coffee machines, as it ensures that all components in contact with coffee, including safety valves, are safe and do not release harmful substances into the liquid. In an industry where food safety is paramount, this certification ensures that machines comply with European regulations and do not compromise consumer health.
Alongside this compliance, there is an increasing demand for cheap products, often utilizing copper alloys instead of stainless steel to reduce costs and benefit from the physical-mechanical properties of the material. Although copper is a suitable material for many applications, it is not always MOCA-compliant, as it can react with hot liquids or other substances, risking contamination of the coffee with heavy metals or other chemicals.
What is Nuova General's Solution?
Our valves are made with 100% Italian materials, ensuring complete traceability and the highest quality. All components comply with FDA regulations, guaranteeing safety and reliability in contact with food and beverages.
Upon request, we offer MOCA certification (Materials and Objects in Contact with Food), certifying the suitability of the materials, tested in certified laboratories, for use in winemaking and brewing processes. This guarantees maximum protection against contamination while adhering to the most stringent food industry standards.
To meet the growing demand for safety valves that meet the needs of the coffee machine industry, Nuova General has developed a line of brass CW510L "LF" (lead-free), low-lead valves, compliant with MOCA as demonstrated by tests conducted in certified laboratories, ensuring safety and optimal performance in contact with food and beverages.
Certifications and Standards for the Coffee Machine Industry
The MOCA certification (D.E. 1935/2004) is essential for safety valves installed in coffee machines, as it ensures that the materials in contact with coffee or other beverages are safe and comply with European health and food safety regulations. The MOCA certification guarantees that the valves do not release harmful substances into the fluid that comes into contact with the consumer, preventing chemical or physical contamination. For coffee machines, where the quality and safety of the final product are crucial, this certification becomes an indispensable requirement to ensure optimal performance and user protection.
