Commercial freeze dryers, also called lyophilizers, are machines that remove moisture from products to preserve them. The process works by freezing the product and then lowering the pressure around it, allowing the ice to change directly into vapor without passing through a liquid phase.
This technique is widely used in industries like pharmaceuticals, food, and biotechnology. It helps maintain the structure, nutrients, and flavor of the product while extending its shelf life. Commercial freeze dryers are designed for large-scale operations, making them more powerful and efficient than smaller, lab-scale models.
