Introduction to Gas-assisted Injection Molding - Makenica
Liquid nitrogen (LIN) is used in innovative cooling and freezing technologies. LIN is an effective and convenient refrigerant due to its availability, low cost, and inert properties. It is also a practical cryogen for most low-temperature applications because of its extremely low boiling temperature (–195.8°C) and … Visa mer Several cooling techniques take advantage of LIN’s refrigeration capabilities in batch or continuous processes. 1. direct surface (semi-indirect) cooling (Figure 1a). LIN provides cooling via a single … Visa mer LIN refrigeration enables cryogenic milling and grinding to pulverize, to micron- or submicron-sized powders, materials that would otherwise be … Visa mer Cryopelletization is a low-temperature technique for manufacturing pellets that are most often spherical or semi-spherical and range from 0.5 mm to 5 mm in diameter (4). It is often used to pelletize heat-sensitive … Visa mer Lyophilization, or freeze-drying, dehydrates thermally sensitive materials (e.g., proteins) by freezing the material with LIN, followed by controlled sublimation under vacuum. Materials may be freeze-dried to … Visa mer WebbMost injection molders require 99% nitrogen (N2) for their applications. Nitrogen membrane generator systems are effective to approximately 99%, while the PSA … Webb14 jan. 2015 · January 14, 2015. For more than a half century, liquid nitrogen has been used to freeze and chill food products. In the food industry, liquid nitrogen is used most often to power tunnel or spiral freezers for the final food preservation before it is packaged and shipped.
