Why are magnets placed in the doors of refrigerators?
he magnets keep the door shut and help to form an air tight seal between the door and the refrigerator. Also many many years ago refrigerators did not close with magnets and typically closed using a latch. This caused a major problem, there were incidents in which someone would be throwing away a refrigerator and it would be sitting out at the end of there driveway for example. Neighborhood kids would be playing hide and seek and the old refrigerator looked like an appealing place to hide, what kids did not know was that the refrigerator when shut is air tight and that when latched it cant be open from the inside. There were incidents where kids suffocated hiding in old refrigerators. So there was a movement to make refrigerator doors sealable but without the use of a latch, and that is the other reason refrigerators use magnets to hold them shut.
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.
