IMMERSE
Products and packaging which are susceptible to damage can be immersed in water, and are processed under a carefully controlled pressure profile. Water also provides an excellent heat transfer medium. The process is therefore suitable for glass jars and bottles, flexible pouches, semi-rigid punnets and soft packaging e.g. Polypropylene (PP) and High Density Polyethylene (HDPE) bottles. Water immersion with rotation is recommended for products where the colors and flavors are heat sensitive (e.g. milk-based drinks). Water immersion is highly energy efficient by recovering the superheated water for use in the next cycle.

SPRAY
Water spray retorts use nozzles to spray a mixture of steam and water onto the packages to transfer the heat. By using specially designed trays and strategically placed nozzles Molenaar retorts achieve excellent temperature distribution and exceptional heat transfer throughout the retorts. Water spray retorts use less water, and they are very efficient in terms of steam consumption. Dynamic over-pressure control continuously adjusts the over pressure, making Water spray retorts suitable for glass containers, plastic bottles, plastic cups, pouches and punnets.
STEAM
Saturated steam is an excellent medium for sterilizing, since condensing steam results in rapid heat transfer. Venting of the retort is done to remove air, which results in an even heat distribution and quick come-up times. Steam, as a processing medium, is ideal for metal cans: both tinplate and aluminium.
