New Ideas are Always in the Pipeline

CRYOCONNECT^® RM Remote Monitoring

Production operator monitoring freezer performance

Monitor Freezer Performance Remotely

The CRYOCONNECT^® RM remote monitoring system provides the ability to view real time freezer operation and analyze operational data wherever there is online web access.

Remote Freezer Monitoring

Online Monitoring Provides Real-Time and Historical Data

Operations managers now have online access to freezer data wherever and whenever is most convenient, so freezer operations can be analyzed to maintain optimal performance. The Linde CRYOCONNECT^® RM remote monitoring system uses operational sensors to collect data, then connects the sensor information with line managers, system operators, and, when needed, Linde technicians. The operator interface provides a system overview, letting users see quickly whether the freezer is functioning properly. Not only does the system offer secure remote data access to current operations, but the interface allows customizable graphic reporting and mobile alerts, along with access to historical data. This gives users information to increase the uptime of processing by adjusting and troubleshooting an operation in minutes.

Remote Assistance and More

The CRYOCONNECT^® RM remote monitoring incorporates the ability for Linde’s freezer technicians to “dial into” the system at the specific request of the customer. If the system’s additional information does not provide enough details to solve a technical issue, your operation management team can communicate with our service center and Linde can look at your data to provide further insight. Additionally, an automated monthly email report from the remote monitoring system with summary data is organized into an easily understood format. The automated email reduces the learning curve and lets you begin acting on data right away. As you get more familiar with the system, you can then expand your use of more customizable features.

CRYOLINE^® RC Rapid Crust Freezer

Rapid Crust Freezing for Productivity Improvement

The CRYOLINE® RC rapid crust freezer is a specialized semi-batch unit built for freezing the surface of larger pieces of food products prior to portioning using methods such as slicing or dicing. The CRYOLINE RC freezer is best suited for crust freezing pre-cut deli meat such as ham, sausage, and cooked meat, or portioned whole cuts such as pre-cut steaks. Cryogenic freezing allows very short dwell time with just-in-time operation with the slicer, resulting in space savings. Proper crust freezing helps to preserve product quality by reducing the risk of tears and crumbling while also increasing portioning accuracy due to the firmer product structure.

Liquid Nitrogen is Used to Achieve an Optimum Rate of Heat Transfer

High-velocity nitrogen gas flow is parallel to the product’s transfer pathway and results in a high rate of heat transfer while providing uniform crust freezing across the surface of the products. The nitrogen flow is generated with a centrifugal fan and funnels through tight spaces between products. This funneling creates high-velocity nitrogen gas flow, which effectively takes heat away from the food. In addition, liquid nitrogen is also directly sprayed into the gas stream to maximize the rate of heat transfer. The nitrogen continues to circulate for a given dwell time before exiting the system through an exhaust vent. CRYOLINE RC rapid crust freezer

NITROBOOST™ Supplemental Refrigeration System

Cost-Effective Capacity Optimization

The new liquid nitrogen powered NITROBOOST™ supplemental refrigeration systems give manufacturers the ability to maintain target operating temperatures in their existing mechanical tunnel and spiral freezers (NITROBOOST™ ST) or blast-style freezers (NITROBOOST™ BL). This avoids production downtime and the related temperature issues that occur from high heat loads and exceeding the freezer’s capacity. Made up of heat exchanger coils, using liquid nitrogen, the NITROBOOST systems are compact in size yet deliver substantial additional refrigeration capacity. Small enough to fit within or mounted on existing spiral or tunnel freezers. the systems use liquid nitrogen in closed-loop coils to efficiently and rapidly lower circulating air temperature.

A Boost for the Blast Freezer

Mechanical blast or shock freezers can struggle to reach their target operating temperature in an acceptable amount of time due to inadequate refrigeration capacity. It is often difficult for food processors to address temperature issues, since replacing the freezer or upgrading the mechanical refrigeration system can be very expensive and require weeks of downtime. Added to a blast or shock freezer, the NITROBOOST™ BL system from Linde helps under-performing or overloaded freezers reach the desired operating temperature faster. Processors can now keep products within specific temperature ranges and avoid the need to reduce freezer loading or operate additional hours or shifts.

Mechanical Spirals and Tunnels Also Benefit

The new liquid nitrogen powered NITROBOOST™ ST supplemental refrigeration system gives processors the ability to maintain target operating temperatures in their existing mechanical tunnel and spiral freezers. This can avoid production downtime and the related temperature issues that occur from high heat loads that exceed mechanical freezer capacity. The NITROBOOST ST system detects when the mechanical freezer is trying to reach its target operating temperature and triggers the liquid nitrogen flow to accelerate the cool down process to maintain a consistent operating temperature. The NITROBOOST ST system coils also can be set to defrost at different times relative to the mechanical system to optimize freezer production, defrosting and sanitation schedules.
