Cryogenic cooling has an array of industrial applications, including hemp and food processing. This course explores the cryogenic process, discusses its applications, combination of approaches and describes current equipment needed to handle liquid nitrogen for successful processing.

Using a Multi-Method Approach to Temperature Control in Food Processing
As two of the most common methods for food preservation, chilling and freezing can be done in a variety of ways. But because cooling tends to be more difficult and more expensive than heating, employing multiple freezing and cooling methods to achieve the desired temperature can provide many benefits. This article explores multiple cooling approaches and their benefits, from energy efficiency and product quality to cost control and operational benefits.

Considerations for Cryogenic Industrial Process Cooling Insulation
Industrial process cooling systems can operate at very cold and even cryogenic temperatures. However, the specification of mechanical insulation in process cooling systems requires considerations beyond temperature. This article discusses several insulation characteristics to keep in mind for cryogenic systems, from insulation thickness to metal jacketing options to compressive strength considerations.

Cryogenic Solutions for Compliant Industrial Hemp Processing
Liquid nitrogen has been used for decades to cool products in the food processing, pharmaceutical and nutraceutical industries, but it is also proving to be advantageous in a relative new arena: the industrial hemp industry. This article discusses how LIN is being used for cryogenic cooling to meet increasing quality and safety requirements for hemp processing.
