air loses and gains heat through convection. The cooling source of the freezer is towards the back. As the warmer air from outside is convected in the cooler air is convected out cooling the food on its way. Eventually the food will just be slightly cooler than its surroundings.

How do blast freezers work?
Blast freezers are designed in many ways for fast freezing various food products such as fish and meat by blowing very cold air upon the products to be frozen for 8 to 24 hours until the frozen product reaches a core temperature of minus 12 to minus 20 C. Blast freezers are operated at minus 40 degrees C or lower. A typical blast furnace consists of a small insulated cabin where strong fans are place right behind or on top of a cooling coil grid which is open in the front or partitioned to ensure air flow through the produce and back to fan suction -the strong gush of cold air hits the product to be frozen racked or hung right in front and the job is done. Blast freezers could have a single door for loading and unloading or with separate doors for the same.

Finding Affordable Commercial Freezers?
When grocery stores and restaurants need storage for their frozen goods, only commercial freezers can get the job done. Commercial freezers vary in design, size, and function. Grocery stores typically only need freezers that store food at thirty two degrees. These freezers are often just larger versions of the freezers that the average consumer use at home. These freezers are often in a box style, which allows for individual freezers to carry certain foods, which makes organization easier. Larger stores can even have entire rooms dedicated to the preservation of food. These commercial freezers are actually built into the buildings, as the entire room is just a giant freezer. Commercial freezers are also used in small businesses, such as ice cream shops. These freezers are often smaller than most commercial freezers, but are still much more powerful than those that we use at home. There are also freezers that are dedicated to to have dual functionality. These freezers have glass doors so customers can see that is in them, and they can still keep the food at the required temperature. These freezers are made to order and are only for commercial use, and are often purchased in bulk so that they may comprise entire aisles in a grocery store. While the commercial freezers that are used in stores are basically larger models than what we have at home, the freezers used in the actual manufacturing of the food are much different. These commercial freezers are very powerful, so powerful that the rooms that they are in have to be labeled as hazardous. These freezers are often called flash freezers. This is because after the food is made, it needs to be preserved as soon as possible to retain its freshness after cooking. These freezers often span multiple rooms and feature large conveyor belts that transport the food. These freezers can instantly freeze food, and drop to temperatures of -120 degrees fahrenheit almost instantly. Freezers are an integral part of the commercial food industry. Without them, food wouldn’t be able to be transported across the nation, and across the country. Commercial freezers range in size and power, but there are several different models that are available for consumer and business use.
