What is a plate evaporator?

They are pretty similar to a plate heat exchangers. They have large surface areas. It's used for removal of liquid containing in food and in beverages. The real definition is by the css.


What will happen to juicy vegetables letf on a plate in a freezer for a long time?

They will dry out, but not in a good way. They would be freezer-burned rather than freeze-dried.


How cold is a regular piece of ice?

Its temperature would be a maximum of 0°Celcius. Typical temperatures depend on where it's from. For example, a deep freezer might have its thermostat set to -20°C, in which case the temperature of the ice would be extremely close to -20°C when removed from the freezer. It would start warming up from that moment on. A regular piece of ice sitting on a plate (ready to use) would be about -2 to 0°C

What is the temperature of iron in room?

The temperature of the sole plate of an electric iron depends on the setting of the number of "dots".Three dots or hot iron. Maximum sole plate temperature of 200 °C.Two dots or iron at moderate temperature. Maximum sole plate temperature of 150 °C.One dot or iron at low temperature. Maximum sole plate temperature of 110 °C.Nevertheless the accuracy of the sole temperature in relation to the iron setting is the responsibility of the iron manufacturer.

Can you give me a tecnical description of the refrigerator?

In short, a refrigerator is a heat pump, thus the heat is pumped from the inside compartment of the refrigerator and released outside. A refrigerator consist of three active parts, a compressor, condenser and a evaporator, the compressor is pumping the refrigerant that is in a vapor form to a higher pressure so that it can change to a liquid form, but because of the high temperature generated in the compression stage and the friction of the gas through the tubes, it is not possible to liquefy until its cooled down. That is the purpose of the condenser, it is made up of a long metal tube that is coiled and covered with a heat sink to help get rid of the heat, that is the black plate at the back of the refrigerator, the liquid refrigerant is then passed through a dryer/filter to remove any sediments and possible moisture from the refrigerant then through a thin copper tube that is called a capillary tube, to the evaporator, that is the plate at the inside back of the refrigerator, in the older type single door refrigerators it is the freezing compartment at the top.Because of the much lower pressure in the evaporator the liquid refrigerant immediately start to evaporate back to a vapor form, taking the heat out of the refrigerator inside compartment and returned to the compressor for recycling. The temperature of the refrigerator is controlled by switching the compressor on and off by means of a thermostat, where the sensor of the thermostat is connected to the evaporator. At the highest point of the superheat (superheat is the difference in temperature between the inlet and outlet side of the evaporator).


How long does it take for a hot plate to cool?

It depends on the ambient temperature, and the mass, composition and temperature of the hotplate.


How many amps are needed for a freezer?

You need to look at the rating plate on the freezer. My Kenmore upright freezer draws 5.0 A. Look for a number followed by the word amps or something like 5.0 A.


What unit does a hot plate measure in?

* A hot plate should measure temperature because when you use it, it will boil because of the heat coming up. Since there is heat, it measures temperature.
