PT. TIARA SERVICE CENTREHisaka Hot Water Spray Type Retort Sterilizer (RCS) is a high-temperature, high-pressure sterilization system designed for uniform temperature distribution and versatile container compatibility. Through an indirect spray mechanism, heated water is sprayed over product trays, ensuring consistent sterilization across all packages while accommodating air-containing containers that require precise pressure control during the sterilization process.
No variation in temperature throughout the retort chamber ensures consistent sterilization results. The indirect spray system provides even heat distribution across all tray levels, eliminating cold spots and guaranteeing food safety across all products in every batch.
Possible to adapt for air-containing containers such as retort pouches, plastic trays, and semi-rigid packaging. The system provides precise overpressure control to prevent container deformation during high-temperature sterilization.
High-temperature, high-pressure sterilization achieves commercial sterility for low-acid foods. Capable of reaching temperatures above 121°C (250°F) with precise pressure control for various container types.
Accommodates various container shapes and sizes including cans, bottles, pouches, trays, and jars. Quick changeover systems enable efficient production of multiple product types.
The Hot Water Spray Type Retort Sterilizer operates through an indirect spray sterilization process with precise temperature and pressure control:
Products in containers (cans, bottles, pouches, trays) are loaded onto multi-level trays and transferred into the retort chamber.
A predetermined amount of water is introduced into the chamber bottom for circulation through the spray system.
Hot water is sprayed through side-mounted spray nozzles across the tray levels. Steam injection heats circulating water to sterilization temperature (121-135°C) without direct contact with products.
Overpressure is maintained using compressed air to protect air-containing containers from deformation during high-temperature processing.
Products are cooled through indirect water spray circulation while maintaining overpressure. Cooling water can be sterilized to prevent post-process contamination.
Sterilized products are unloaded and transferred to next processing stage (labeling, packaging, warehousing).
Hisaka Hot Water Spray Type Retort Sterilizer is ideal for sterilizing various packaged food products:
Vegetables, fruits, meats, seafood, and ready meals in metal cans.
Sauces, soups, beverages, and liquid foods in glass or plastic bottles.
Flexible packaging for ready-to-eat meals, curries, and Asian cuisine.
Semi-rigid containers for prepared foods, noodles, and complete meals.
Purees, formulas, and specialized nutrition products requiring strict sterility.
Wet pet food in cans, pouches, and trays requiring commercial sterility.
Indirect spray mechanism ensures uniform heat distribution across all tray levels with minimal temperature variation (±0.5°C), guaranteeing consistent sterilization results.
Handles air-containing containers (pouches, trays) with precise overpressure control to prevent package damage.
Rapid heating and cooling cycles reduce total processing time, improving production efficiency.
Recirculation system reduces water consumption and energy costs through heat recovery.
