At first you need to cool the food at required temperature and must keep it at the same cool condition inside the fridge to save energy by not opening its door.
Your direction of thinking is exactly correct . cool food first. Keep it for longer time. then you reduce the compressor running time and frequency. then you save energy...good.
Refrigerator Must Open if Used. Despite the model or a technology incorporated of a particular refrigerator, user has to open its doors to store or take out the goods. When the door remains open, warm and moist ambient air will flow in and will mix with the cold air inside the refrigerator. Moisture transfer increases with the number of door openings. If the blower fan is turned on, the flow rate of cold air inside the refrigerator cabin will be accelerated, resulting an out flow to the atmosphere through its square area of the opening thus convective and radiative heat transfer increases. Masjuki et al. (2001) investigated that about 10 Wh increases in energy consumption for each door opening of 150 l refrigerator-freezer. Further, a temperature rise of 10 to 20 degrees of Celsius could beobserved during open door condition.
Refrigerator is one the key electrical appliances which is plugged to the electrical supply round the clock in a common family. It has approximately 15 to 18 hrs of continuous compressor operation time. Hence, a refrigerator consumes approximately 48 to 58 kWh per month as per the previous surveys. Therefore, refrigerator grabs 30 to 50 per cent units of the total monthly electricity consumption.
So what to do...?
I have invented very simple and cost effective system to overcome this. We can save 14% energy from any model. The concept of "Door Screening System"(Patented for 20 years) can save 7 to 12 kWh per month from your refrigerator or bottle cooler.
I'm looking for investor who could join me to keep the world more greener for future generations.

What ways can you use electricity?
The ways that you can use electricity include heating and cooling your home. You can use electricity for things that include cooking, heating water, keeping food cold, and for entertainment.
When cooling food you should use deep pans to bring the temperature down True or False?
False
What is Proper cooling consists of the following methods except?
Proper cooling consists of methods such as refrigeration, ice bath, and blast chilling. Not a proper method for cooling is leaving food at room temperature to cool down.
What mechanisms break down food?
first it's the teeth and saliva. after you swallow the food it is the stomach acids that break down the food.
What all cells need light or blood or electricity or food?
Food and Electricity :) hope it helps!!
When food is swallowed it first passes down?
Esophagus
When cooling down soup what is the time and temperature specification?
The parameters for safely cooling food is the same for all cooked potentially hazardous foods:Within 2 hours, cool from 135F to 70FWithin 4 hours, cool from 70F to 41F
Do the muscles in the gullet help to push the food down to the stomach?
The mouth chew the food first, a muscle at the back of the mouth forces the food down your gullet and the gullet's muscle forces it down into your stomach.
Has food got electricity in it?
No why would it have electricity in it . If it did we would be shocked when we ate it!
What waste can you burn to create electricity?
Food waste can create electricity.
How do humans digest food?
first humans chew the food which the saliva helps you swallow the food then it goes down the trachia which it has muscles that help the food go down to your stomach and then the fun slide
Why is a cooling triangle used in food technology?
Evaporative cooling triangle hat keeps your head cool.
