Rotary spray sterilization retorts are primarily suitable for packaged foods that require uniform, efficient thermal sterilization and have a certain degree of fluidity or consist of solid-liquid mixtures. The core applicable categories include:

1. Canned Foods: Such as canned meats, canned fish, and canned fruits. The rotation prevents sedimentation of the contents, while the spray ensures even heat distribution.

2. Sauces and Soups: Such as tomato sauce, jam, thick soups, and condiments. Rotation aids in stirring, preventing localized overheating or insufficient sterilization.

3. Beverages: Especially juices with pulp or particles, tea drinks, and dairy beverages. Rotation prevents pulp sedimentation, achieving uniform sterilization.

4. Porridge and Ready-to-Eat Dishes: Such as mixed congee (e.g., eight-treasure porridge), vacuum-packed corn, and beans. Rotation prevents clumping of grains or beans, ensuring sterilization effectiveness.

5. Retort Pouch Foods: Meat products, poultry, and aquatic products packaged in retort pouches. Spray heating is highly efficient, and rotation provides more even heating.

Its advantage lies in the movement of food during sterilization through rotation, combined with superheated water spray, which can significantly shorten sterilization time and better preserve the food's flavor, color, and texture.
