The Hydromatic continuous sterilizer consists of four or more towers or " legs" , each with a height of up to twenty meters. The first leg serves as a preheating section, in which a hydrostatic column serves as an inlet lock. The second tower comprises the sterilizing section, where the product is heated to the requisite sterilization temperature with the help of steam or superheated water. After leaving the sterilizing section, the product carrier ascends through the hydrostatic cooling leg. With the pressure gradually decreasing and the product gradually cooling, spray water jets provide additional cooling. Finally, the cooling cycle is completed in the fourth tower at atmospheric pressure.
