Continuous spray dryer for permeate powder
Efficiently transform liquid whey and milk into high-quality, non-caking, and non-hygroscopic permeate powders with seamless integration into your production line, optimizing powder functionalities and reducing energy consumption.

Processes Permeate Powders with Precision and Efficiency
The Tetra Pak® Spray Dryer Prolac is engineered to transform liquid permeates from cheese and milk into high-quality, food-grade permeate powders. Specializing in creating non-caking and non-hygroscopic powders, this spray dryer employs a continuous operation process that incorporates spray drying, crystallization, and advanced filtration. Designed for integration in full production lines, it supports capacities from 3 to 8 tonnes of powder output per hour, offering flexibility for dairy producers and whey processors. The system boasts energy efficiency by utilizing a straight tube air distributor and heat recuperator, minimizing electricity consumption. Constructed with hygienic materials, it complies with food safety standards and includes modular components like crystallization belts and shaking beds for versatile functionality. Tailored to handle the challenges of sticky permeates, the Prolac ensures optimal performance with minimal maintenance due to its Clean-In-Place (CIP) system and robust design.
