    AI Overview
    A freeze pulverizer (or cryogenic grinder) is a specialized machine that uses liquid nitrogen or dry ice to embrittle materials, allowing them to be ground into fine powders at temperatures typically ranging from
    −70∘
    𝐶
     to
    −150∘
    𝐶
    . It is essential for processing heat-sensitive, sticky, or elastic materials like plastics, rubber, and pharmaceuticals.

    Key Features and Benefits 
    • Embrittlement: Extreme cold changes material characteristics, making them brittle and crispy for easier grinding.
    • Material Integrity: Low temperatures prevent oxidation and chemical changes, preserving the flavor, color, and nutritional value of food and herbal products.
    • Efficiency: Enables the grinding of materials that are difficult or impossible to process at ambient temperatures (e.g., tough fibrous tissues, rubbers).
    • Superior Powder Quality: Produces fine, uniform, and free-flowing powders. 
    Common Applications 
    • Plastics and Elastomers: PET, PE wax, PA, and other thermoplastics that soften during conventional grinding.
    • Food and Pharmaceutical: Spices, herbs, oils, and substances rich in sugar.
    • Biological Samples: Hard-frozen animal or plant tissue (skin, cartilage) often using a laboratory-grade BioPulverizer. 
    Common Types of Freeze Pulverizers 
    • Industrial Cryogenic Pulverizer: Large-scale systems used for heavy-duty, high-capacity grinding.
    • Freezer/Mill (Laboratory): Smaller, often automated devices used to grind samples in sealed vials, such as those from SPEX SamplePrep.
    • BioPulverizer/Bessman Tissue Pulverizer: A specialized, manual tool for small-scale freeze-fracturing of tissue. 
    When choosing a pulverizer, considerations include product type, required particle size, and production capacity.

    How to pulverize frozen tissue?
    Place the frozen tissue piece in the LN2 in the mortar, and let cool for 1 min to get brittle. Then carefully pound and grind the tissue into a fine powder. With a precooled spatula, scrape the powder into a heap and transfer to an Eppendorf tube sitting on dry ice.
