La sanificazione degli stampi microperforati

REGENERATION OF MICROPERFORATED MOLDS

DISCOVER THE PERFECT PROCEDURE TO RESTORE WHEY DRAINAGE CAPACITY AND REDUCE FUNGAL CONTAMINATION

The sanitation of microperforated molds represents one of the most critical cleaning applications in the dairy industry. Several factors contribute to making cleaning procedures difficult or ineffective:

• Polymer material of the molds
• Non-smooth surfaces
• Extended contact time with curd and whey
• Crystallization of salts contained in whey
• Dehydrated protein residues
• Short contact time with the cleaning solution in tunnel washes
• Use of acidic detergents and/or ineffective concentrations due to limitations on phosphate and/or nitrate discharge
• Insufficient or improperly applied mechanical cleaning energy

After several production cycles and ineffective cleaning, the whey drainage flow is often reduced due to the clogging of microperforations by mixed-organic contaminants that develop into biofilm over time. The clogging of micropores caused by biofilm leads to technological issues in cheese production, including shaping, aging, and fungal contamination on the rind.

Thanks to its comprehensive range of detergents for the dairy industry, AEB offers a regeneration procedure for molds that removes both biofilm and mixed-organic contaminants through a shock treatment that avoids using inorganic acids or products harmful to wastewater treatment systems.

REGENERATION PROCEDURE FOR MICROPERFORATED MOLDS

Step 1 - BIOFILM Removal

Prepare a 1.0% solution of the enzymatic detergent REMOVIL EPS
Heat the solution to a maximum of 45°C
Immerse pre-cleaned molds from the tunnel wash, ensuring the solution temperature is between 40 and 45°C
Let soak for at least 1 hour and rinse the molds thoroughly

Step 2 - Elimination of Mixed-Organic Contaminants

Prepare a 5.0% solution using the caustic monophase detergent DAIRY MPV
Heat the solution to 70°C
Immerse the molds treated in the previous step, ensuring the solution temperature is between 60 and 70°C
Add ADDING OX at 1.0% to the cleaning solution
Let soak for at least 1 hour and follow up with an acidic wash in the tunnel.

A straightforward, effective procedure that ensures you achieve the best results for your production.
