This innovative Pasteurizer, Roaster and Briner allows processors to prioritize product quality while maintaining a validated kill step for food safety. It enables customizable brining and roasting to meet specific product requirements.
Unmatched Quality and Consistency
CoolSteam® Black empowers food processors with precise control, excellent product quality, and standardized results. Whether pasteurizing, brining, or roasting, the system ensures every nut undergoes uniform processing, yielding unparalleled consistency and shorter processing times.
Ready to Pack Product
Ready to pack cooled product; no need for additional refrigeration.
Eliminate Product Handling
The system's design eliminates the need for product handling between all enclosed processing stages, offering a ready-for-packaging product without any outside contact.
Force Convection High-Velocity Air
Precision Roasting® harnesses Forced Convection, a principle akin to the rapid hot air circulation in an air fryer, to achieve efficient nut roasting and pasteurization. This approach ensures uniform temperature distribution, minimizing cold spots and enhancing heat absorption.
-
Consistency: Forced convection guarantees even cooking throughout the product bed, producing uniformly pasteurized and roasted product. The CoolSteam design team utilizes computational software to optimize fan-generated airflow, ensuring comprehensive coverage and a crispy outer layer.
-
Faster Processing: Continuous hot air circulation accelerates pasteurization and roasting processes, significantly reducing processing time compared to traditional methods.
-
Crisp, Moisture Neutral Texture: Forced convection aids rapid moisture evaporation, leading to the coveted crispy texture vital for achieving ideal crunchiness and flavor.
Pre-conditioning step ensures tree nuts maintain their natural crunch and texture by gradually increasing product temperature, preventing internal or external condensation.
Preheat
Cool
Cooling stage ensures nuts are brought below 80°F, facilitating seamless retail or bulk distribution packaging.
Roast / Dry
CoolSteam® Black's Precision Roaster utilizes forced convection for accurate drying or roasting, maintaining consistent results without over- or under-roasting.
Utilizing all-natural low-temperature steam. The CoolSteam pasteurization technology achieves a 5-Log Reduction of pathogens for a validated kill-step
Pasteurize
Continuous 5-Step flow
CoolSteam® Black features distinct steps that make it the preferred choice for pasteurizing and roasting tree nuts. The system can be tailored to specific customer needs, including stand-alone systems. The system's versatility allows processors to decide which zones to include. Exit, CoolSteam® Black reduces complexity for processors and streamlines equipment needs by replacing multiple units from different brands (utilizing multiple vendors) with a single, comprehensive system and one local service team.
Brine
The Intraflow Briner, uniformly applies salt brine continuously, easily accommodating salted or unsalted products during the same process with no external product handling.
Product Applications
Consistently Excellent Product Quality. Proven on the Most Sensitive Nuts. Validations for Almonds, Pistachios, Seeds, Walnuts, Cashews, Macadamias, Pecans. Thanks to its integrated Intraflow briner and conveyance capabilities, it easily accommodates both salted and unsalted products, roaster or raw pasteurized.
Intraflow Briner
Laitram Machinery’s Intraflow Briner is a unique brine application system that can be used as pass-through conveyance for non-salted products during pasteurization and roasting.
Intraflow creates a continuous product flow between CoolSteam Pasteurizer and Precision Roaster, eliminating additional material handling through conveyance, transfer points, or oscillating conveyors as is needed with traditional drum brine applicator systems.
-
Intraflow utilizes a counter-flow process to consistently apply salt brine in each trough for even, full coverage on each nut.
-
Tree Nuts never sit stagnant in Intraflow. The product's constant movement through the system ensures consistent and even coverage. The nuts are de-watered and transported directly to the roaster.
-
All controls, including auger speed and salt brine flow rate, are integrated into one easy-to-operate control panel. Real-time feedback and data are captured in one-second intervals.
-
Cleaning and sanitizing the augers is easy with an automated CIP cycle that utilizes high-pressure nozzles to clean the Intraflow Briner.
Briner Operating Principle
The product Cascades from the Pasteurizer Belt Directly into the Briner. The brining solution is supplied from the Brine Mixing Skid.
The brine skid consists of a mixing and holding tank to create customized brining solutions for any product recipe.

What Our Clients
Say About Us
Red River Foods installed a Laitram pasteurization system at our Richmond facility to serve as a critical kill step prior to roasting. The equipment has performed reliably and consistently, providing effective protection against foreign organisms while integrating seamlessly into our existing processing flow.
One of the most valuable features of the system is its flexibility. The pasteurizer allows us to precisely control temperature, time, and processing conditions based on nut type and size. This enables us to either roast or dry product as needed by adjusting roaster settings, while maintaining consistent quality outcomes. The control panel is intuitive and user-friendly, making day-to-day operation efficient for our team.
Laitram worked closely with us to customize the belt design to accommodate smaller productssuch as pine nuts. While the standard design is typically suited for larger pieces, their team modified the belt to ensure proper airflow and performance for our specific needs. The stainless steel construction supports both durability and food safety requirements.
Cleaning and sanitation are straightforward. The integrated belt cleaning system allows for easy application of soap or sanitizer, which simplifies routine maintenance and supports our food safety protocols.
In addition to the equipment itself, our experience working with Laitram has been excellent. Their team is both proactive and responsive, with strong communication throughout installation and ongoing operation. The safety features of the machine are also outstanding, including safeguards that prevent access to components while temperatures remain unsafe.
Overall, the Laitram pasteurization system has met our operational, safety, and quality expectations, and the partnership has been a positive and professional experience.
