Can we quickly cook foodstuffs in hills?
Cooking is the mandate work ever, which we do or need in any way for our survival. In this rapid lifestyle, we opt for different accessories, technologies, and methodologies to decrease the cooking time. Let us discuss basic technical facts and ways to decrease the cooking time.
Modes of heat transfer
Let us begin the discussion with basic modes of heat transfer since boiling occurs when heat transfer from one place to another place, isn’t it?
There are three modes;
Conduction – Heat transfer during physical contact
Convection – Heat transfer due to density difference
Radiation – Heat transfer by electromagnetic radiation
Boiling point
The next important thing is to know the specific temperature requirements, the temperature at which the system boils is the boiling point, however, it does not depend only on temperature but also pressures.
In detail, the temperature at which, when the vapour pressure equals the system pressure or atmospheric pressure is the boiling point. The pressure exerted by the vapour of the content is vapour pressure.
Now, let me answer this blog title (Can we quickly cook foodstuffs in hills?). Actually cooking in hills is difficult (slow) because the atmospheric pressure is low in altitude. Thus, the boiling point of water gets reduced. Sequentially, cooking is difficult on hills.
Pressure cooker
Shall we use a reactor to cook fast? Yes, we can say pressure cooker as a simple domestic reactor. Since it utilizes steam energy and increases the internal pressure within the vessel. Thus, we can able to cook food very quickly using the pressure cooker. We need to ensure that the vessel contains optimum water level because the low water level will not provide sufficient steam and high water level consumes much gas or electrical energy what we use for cooking.
A good rubber gasket is also mandated to avoid steam leakage to conserve the cooking gas/energy. A durable whistle is required to expel excess steam. A proper safety valve is much important to overcome the issue of the explosion.
If the internally developed pressure is very high and due to any blockage in whistle i.e., safety valve (pressure releasing valve) immediately the sealant polymer material (mostly neoprene) from blowdown device will open and avoid explosion, ensure safety as well. In addition, cooker with electroplated bottom conserves heat energy requirement.
Thermal conductivity
Nowadays copper bottom stainless steel vessels are familiar. Do we prefer that type of vessel to cook fast? Yes of course, because of its thermal conductivity. The ability of a material/substance to conduct heat is said to be thermal conductivity.
Simple tips to reduce cooking time
At last, I conclude the discussion with simple tips to cook fast.
- Plan for cooking earlier
- Prepare ingredients earlier
- Cut unwanted things and then wash the vegetables (Conserves water too)
- Use the bowl to put scraps then and there
- Fine cut vegetable boils quickly
- Use wide pan whenever required
