NutriPure, industrial pasteurizers for Food Pasteurization
Our industrial continuous pasteurizer, NutriPure, efficiently processes ready-to-eat meals, fruit jars, and prepared foods.
Using microwave technology for food pasteurization, this highly flexible continuous system combines fast processing, instant start-up and thermal repetability. It preserves food quality without additives while extending shelf life and ensuring food safety compliance.
Two pasteurization systems tailored to your needs:
NutriPure Flex: High-capacity continuous production
NutriPure Batch: Process development, validation (R&D), and occasional production
SAIREM offers standard and customized solutions for your specific process and production requirements
Key advantages of our Industrial Pasteurizers

Advanced industrial systems for food pasteurization
NutriPure Flex
Industrial continuous pasteurizer
The NutriPure Flex pasteurizer is a flexible modular tunnel system. Our ranges provides efficient continuous microwave heating with flexible power configurations from 24 kW to 180 kW.
Wide Packaging Compatibility:
The industrial microwave pasteurizer handles diverse container types—cardboard trays, thermoformed plastic, paper, wood, glass jars, and pouches.
Processing versatility:
- Pasteurization only
- Combined cooking and pasteurization in a single line
Our industrial pasteurization system adapts to your recipe requirements, production constraints and container formats.
Key features
- Tunnel length: 4 m to 18 m depending on configuration
- Product lanes: 1 to 6 lanes for parallel processing
- Choke height: adjustable from 40 to 100 mm to fit product dimensions
Our pasteurization systems handle diverse applications with capacities adapted to each product and process.
Capacities examples:
- Cooking and pasteurization of RTE meals: from 200 to 500 kg / h
- Pasteurization of already heated ready-to-eat meals: 900 kg/h
- Cooking and pasteurization of fruit jars: 2 t/h
NutriPure Batch
Low capacity or occasional processing
The NutriPure Batch pasteruization system is designed for process development, validation (R&D), and occasional production requirements.
Ideal for food manufacturers developing new recipes, conducting shelf-life studies, or producing small batches, this system provides the same microwave pasteurization technology as industrial lines in a compact, laboratory-scale format.
Key features
- Compact batch configuration for R&D and pilot production
- Precise process control
- Packaging compatibility
