The Pick Sanitary Heater injects steam directly into food products, achieving instant transfer of energy. This compact system heats, cooks or sterilizes dairy products, starches, purees, juices, sauces and other water miscible products on a continuous straight-through basis. It can process slurries including bite-size pieces without damage to product texture or consistency. Uniform heat treatment improves product quality and eliminates burn-on and costly maintenance. It can also be used to heat CIP solutions and inject nitrogen into mayonnaise, edible oils and similar products for improved shelf life.
