Spirox provides a flour cooling solution when a high temperature reduction of the flour is required and flexibility of flour supply to different production lines is required (on/off). Spirox cools the flour in line by injecting it with liquid CO2 that instantly sublimates. The desired temperature is precision controlled by controlling the flow of CO2. Spirox is an ideal flour cooling system for industrial frozen puff pastry or Danish pastries.
