| Hydromatic - Continuous Hydrostatic Steriliser |
 The Stork Hydromatic continuous steriliser 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 sterilising section, where the product is heated to the requisite sterilisation temperature with the help of steam or superheated water. After leaving the sterilising 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.
The hydrostatic principle:
Hydromatics are available in either container-dedicated or super-flexible execution and come in speeds ranging to 2000 containers per minute.

Stork Hydromatic sterilisers operate on the hydrostatic principle, with the pressure of saturated steam in the sterilising zone (red) balancing the weight of two water columns (green) adjacent to the sterilising zone. The sterilisation temperature is directly related to the pressure of the saturated steam. By varying the pressure, the temperature can be controlled. The product containers are conveyed through the machine in carriers fitted between two endless stainless steel chains. An automatic loading and unloading system brings the containers in and out of the carriers. The chain speed is determined by the required sterilisation time, and can be varied as needed.
