Batch retorts can employ various methods of process delivery. Some of which also utilize overpressure or counter-pressure to help protect the integrity of the container during the process (i.e.: to keep the package from bursting as temperature and pressure builds inside the container during the process). Rigid containers, such as steel cans, can withstand large differences between the pressure inside and outside of the container, and therefore these types of containers typically do not require overpressure. They can be processed in a 100% saturated steam environment without the use of overpressure during the heating phases. On the other hand, more fragile flexible and semi-rigid containers cannot withstand high pressure differentials, so air is introduced into the retort to provide overpressure to maintain package integrity during the process. These types of containers require more sophisticated overpressure process delivery methods such as water spray, water cascade or water shower, water immersion or steam-air type systems. Because air is an insulator, a means of stirring or mixing the process media in the retort is required to avoid cold spots in the machine, thus ensuring good temperature distribution throughout the retort and product load. This mixing is accomplished by the different water flow methodologies mentioned above, or via a fan in the case of steam-air retorts, and/or via mechanical rotation of the insert/drum in the case of agitating style machines.
Our wine bottle washer efficiently cleans the most popular types of bottles currently used, including:
Glass Containers: Ideal for reheating food as they are microwave-safe and don&#;t hold odors or stains. They are often used for storing leftovers, sauces, and jams.
Plastic Containers: Widely used for their lightweight and durable nature. They are great for packing lunches and storing dry goods. However, it&#;s important to check if they are BPA-free and microwave-safe.
Stainless Steel Containers: Durable and resistant to corrosion and stains. They are often used in professional kitchens for storing and preparing food.

Ceramic Containers: Often used for baking and serving, ceramic containers can be beautiful as well as functional. They are microwave and oven-safe, but can be fragile.
Silicone Containers: Flexible and collapsible, silicone containers are great for saving space. They are microwave and dishwasher safe.
Aluminum Containers: Commonly used for takeout food, these are lightweight and good for transporting food. However, they are not typically used for long-term storage due to possible chemical leaching.
