CIMMA cryogenic grinding plants: achieve amazing pulverizations with liquid nitrogen

Cryogenic grinding plants made by Cimma use liquid nitrogen to drastically cool raw materials during the size reduction process. This controlled temperature abatement, including effective pre cooling, maintains room temperature conditions or lower to avoid degradation. This is particularly effective in the processing of thermoplastics with low-temperature glass transition and other temperature sensitive materials, preserving their intrinsic properties such as molecular structure, biological activity, and aromatic characteristics. This ensures superior quality of the final product and minimizes degradation.

“Evaluate the performance of materials in the presence of heat. With CIMMA cryogenic grinding, dedicated technologies meet maximum efficiency for outstanding results, adding value to your raw materials.”

Sectors of excellence: agrochemical, food and chemical, and new frontiers

Cryogenic grinding has ideal applications in areas such as agrochemicals, where the integrity of active ingredients, often sensitive to ambient temperatures, is critical to the final product; food, for processing seeds, spices, volatile flavors, and delicate ingredients such as vitamins and essential oils, keeping their organoleptic profile intact even when oils and fats tend to adhere in lumpy masses; and chemicals, for pulverization of substances that have a low softening point. In addition, this technology is expanding into new frontiers such as the recycling of polymeric materials.

Dedicated technology and efficiency: a winning combination for the superior quality of your products

Cryogenic grinding with liquid nitrogen not only improves fragility but also protects materials from overheating by making them more susceptible to grinding, thus optimizing the grinding process. This significantly reduces energy consumption compared to traditional methods. The careful temperature control avoids the risk that materials adhere in lumpy masses, preserving the desired particle size and homogeneity. This results in an efficient process that respects the delicacy of your raw materials, ensuring unparalleled final product quality and paving the way for new formulations and applications.
