What is An appropriate method for cooling a large quantity of food?
A large quantity of food must be cooled by immediate refrigeration. The refrigerator's temperature should be set as cold as possible and, if practicable, the food to be cooled should be refrigerated on shallow trays or dishes to allow for quick cooling. You could also put your trays of food into the freezer until cold, before covering or sealing and refrigerating.A large quantity of food must be cooled by immediate refrigeration.

Which method is NOT acceptable for cooling hot foods for refrigeration?
You should allow food to cool at room temperature. Putting the food in the fridge or freezer before its temperature lowers to room temperature could result in the food being unsafe to eat.
Where the refrigeration changes in a refrigeration system?
at the metering device before the evaporator
Can packaged yogurt ferment before the expiration date?
If the yoghurt is stored at refrigeration temperature then it is unlikely that this would happen (fermentation microorganisms don't work very well at this low temperature).
How do you determine when enough vapor has entered the refrigeration system before you charge refrigerant liquid?
When the refrigerant saturation temperature increases to 36 degrees F.
How long does butter keep at room temperature before bad?
Butter can last for days at room temperature. But it is not recommended to leave it out for that long.
AC sub cooling reading?
How do you measure Sub-Cooling for a R-22 AC system SUB-COOLING IS THE THE "HEAT BELOW SATURATION". THE SUB-COOLING LEAVING THE CONDENSER IS CALCULATED BY TAKING THE (ACTUAL)CONDENSING TEMPERATURE AND THEN SUBTRACTING (MINUS)THE LIQUID REFRIGERANT TEMPERATURE (USE THE CHART)LEAVING THE CONDENSER.=THE SUBCOOLING. NORMAL SUBCOOLING AT THE CONDENSER OUTLET SHOULD BE 10*F. THIS WILL ENSURE THAT LIQUID WILL NOT FLASH INTO VAPOR BEFORE IT GETS TO THE EXPANSION VALVE, SHOULD THERE BE A SLIGHT INCREASE IN TEMPERATURE OR A SLIGHT DECREASE IN PRESSURE DUE TO A PRESSURE DROP. SUB COOLING INCREASES CAPACITY & PREVENTS FLASH GAS IN THE LIQUID LINE AHEAD OF THE EXPANSION VALVE. I HOPE THIS IS VERY CLEAR, AND HELPS U FIGURE OUT HOW TO MEASURE IT. TODD S.

Do beans need to cool before refrigeration?
No
What is non equilibrium cooling?
For binary alloy cooling, the cooling temperation is a range instead of a fixed line. During the transition (the range), equilibrium of two metals take place at each temperature (temp. decreasing), if the equilibrium finished before going to lower temperature , this is equilibrium cooling. If not, this is the one with the word "non". Check more about binary eutectic system. Just trying to answer.
On a 2000 Chevrolet Malibu what is the normal engine temperature?
The thermostat opens at 195 degrees and the temperature will rise to 232 to 235 degrees before the cooling fan comes on to cool it down.
What an accumulator in refrigeration system?
right before the compressor
What is an ambient food?
Ambient food is food which is kept and served at the same temperature as room temperature. I.e it is food which does not require refrigeration or heating before eating.
