A cold plate (also called a holdover plate) is a large tank inside your refrigerator or freezer box filled with a solution that freezes and melts out at a temperature lower than water (20 degrees for a refrigerator, -10 degrees for a freezer). The energy stored in cold plates then provides cooling for 24 hours or more.

Plate freezers are used to freeze flat products, such as pastries, fish fillets, and beef patties, as well as irregular-shaped vegetables that are packaged in brick-shaped containers, such as asparagus, cauliflower, spinach, and broccoli. Plate freezers are commonly used for freezing brick-shaped packaged products.

Refrigeration systems and food freezing There are two main types of freezing system: mechanical (which use a circulating refrigerant to reduce the temperature of air or a liquid which is passed over the food) and cryogenic (which use the direct application of liquid nitrogen or carbon dioxide onto the food).

Rate & Review. A method for food manufacturers to freeze food items, such as poultry and beef, by exposing a food product to liquid nitrogen for a period of 6 to 10 seconds. It is often used to prepare a cooked product for further freezing.

Immersion freezing is often done with liquid nitrogen.

Compared to conventional freezing techniques, the cryogenic method has the following advantages: rapid freezing, inhibition of bacterial growth, limited dehydration, considerable reduction of quantitative losses, good retention of original quality attributes, maintenance of the appearance and taste of the food.

Cryonics procedures may begin within minutes of death, and use cryoprotectants to prevent ice formation during cryopreservation. It is, however, not possible for a corpse to be reanimated after undergoing vitrification, as this causes damage to the brain including its neural networks.

Liquid nitrogen at −196 °C or carbon dioxide at −79 °C is introduced at the outfeed end of the freezer, directly on to the product. The low temperature of the liquid and vaporous nitrogen or carbon dioxide provides rapid freezing, which can improve quality and reduce dehydration for some products.

Boynton Beach company provides ambulance transportation for people who want their bodies frozen in a process called cryonics. Upon death, you can freeze your brain, your head or your entire body. You can be transported by a special vehicle that starts the freezing process immediately.

“There is absolutely no current way, no proven scientific way, to actually freeze a whole human down to that temperature without completely destroying — and I mean obliterating — the tissue,” says Shannon Tessier, a cryobiologist with Harvard University and Massachusetts General Hospital.

Prices with other organizations can be as much as $200,000 or more for whole body cryopreservation and $80,000 for a “neuro” (head-only) option. With CI, a whole body cryopreservation costs as little as $28,000.00, rendering an alternative “neuro” option unnecessary.

7. Ted Williams is without a doubt the most famous cryogenically frozen person (that we know of). But the circumstances surrounding his freezing are a bit controversial.

Cryosleep is “sleeping” or “hibernating” for long periods of time in a controlled environment. Cryosleep is featured in the film Avatar, where Jake Sully and other passengers cryosleep while they travel to Pandora. While cryosleeping, or “in cryo”, a person does not age.
