Moto was a molecular gastronomy restaurant in the Fulton River District of Chicago, Illinois known for creating "high-tech" dishes which incorporate elements such as carbonated fruit, edible paper, lasers, and liquid nitrogen for freezing food. [1] Moto was run by executive chef Homaro Cantu until his suicide in 2015.
Cryogenic IQF freezers immerse the product in liquid nitrogen at very low temperatures, freezing it rapidly while continuously moving the product to avoid block or lump formation. [5] Although this method shows good freezing results, it might lead to higher processing costs per weight of product due to the cost of the liquid nitrogen required.
Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C (68 °F), a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space. In an incident on January 12, 2006 at Texas A&M University , the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed.
This rapid freezing is done by submerging the sample in liquid nitrogen or a mixture of dry ice and ethanol. [6] American inventor Clarence Birdseye developed the "quick-freezing" process of food preservation in the 20th century using a cryogenic process. [7] In practice, a mechanical freezing process is usually used due to cost instead.
Dippin' Dots are stored and transported at –40 degree Fahrenheit (–40 °C), which is colder than most frozen foods require. The company's development of ultra low temperature freezers, proper storage and transportation got the company involved from about 1988 with selling their equipment for other uses, such as preserving microbiological cultures for fermentation.
Typically, a sample is plunged into liquid nitrogen or into liquid ethane or liquid propane in a container cooled by liquid nitrogen. The ultimate objective is to freeze the specimen so rapidly (at 10 4 to 10 6 K per second) that ice crystals are unable to form, or are prevented from growing big enough to cause damage to the specimen's ...
The brand uses brewing technology and flash-freezes it using liquid nitrogen for preservation. [3] The headquarters of Cometeer coffee company in Gloucester, Massachusetts. The company's primary product is single-serve flash-frozen coffee capsules, but it also offers a subscription service that delivers frozen capsules to customers regularly.
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.
