Why are pressure cooker used in cookery?
cooking food faster than conventional cooking
How much do cooking times change when using a pressure cooker instead of a normal pot?
Between cooking with a normal pot and a pressure cooker the difference in terms of time is not much. The pressure cooker can be used depending on the type of food that is cooked.
Why pressure cooker is used for rapid cooking?
To know how a pressure cooker works you must know the physics behind it. The boiling point of water is 100°C. When boiling with in a pot with no cap, no matter how much you heat, it will never go past the temperature of 100°C because of evaporation. Also the vaporized steam is the same temperature of the boiling water. So when you cook with a pot of water this time with a sealed cap, as you try to add more heat by increasing the temp., all that will happen is that the vapor will try to escape but because it is a sealed environment it will not be able to escape resulting in the build up of pressure (or force/area). The temperature and pressure will have a direct proportional relationship so as one increase so does the other. Also steam has 6 times the heat potential when it condenses (changes from gas to liquid state of matter) on a cold food product. The build up of pressure and heat potential are two factors which enable pressure cookers to cook foods faster and more efficiently. In pressure cooker the pressure develops inside the vessel as time goes on. As pressure increases the boiling point of water also increases. Food inside the pressure cooker cooked very fast because of high boiling temperature, means the food is not cooked at 100 C but much higher temperature than 100 C. Rapid S Pressure cookers generally operate at 15psi (~760mmHg) above atmospheric pressure. Since atmospheric pressure is 14.7 psi, the pressure within the cooker is about double the atmospheric pressure. Once the operating pressure is attained, the temperature in the pot stabilizes at the boiling point for water at that pressure, which is about 120 C (248 F) at 2 atmospheres of pressure. Further temperature increase is prevented since the pressure is stabilized by the constant venting of steam from the cooking vessel. If the temperature is raised by only 20 C above open pot boiling, why is the cooking time so much faster? The answer is that cooking results from chemical reactions in the food, and the rate at which all chemical reactions occur depends on the temperature. The temperature dependence of reactions is variable, but a rough rule of thumb is that the rate will double for every 10 C increase in temperature. Therefore the reactions that occur during cooking will occur roughly 4 times faster in a pressure cooker at 120 C, and the food will cook in one quarter of the time.
What is the difference between a pressure cooker and a vacuum pressure cooker?
A pressure cooker uses steam from water to cook food and is usually found in a residential setting. A pressure fryer uses oil to cook the food. Pressure fryers are only found in restaurants and are generally used to fry chicken.
Can griddles be used with pressure cookers?
Of course it will work. The griddle size and the cooker size needs to allow the cooker to sit flat on the griddle to allow efficient transfer of heat. Check griddle temp with cooking thermometer for correctness.
Getting the Most Out of Your Pressure Cooker?
Adding home appliances to your kitchen should make the job of preparing and cooking food easier and faster. A pressure cooker is a great addition to the regular cooking tools that you have and once you know how to use it properly, you really can get a lot of life out of it. All pressure cookers use the same basic principles to cook food, but some are easier to use than others and other features are just cosmetic. Get to know exactly how your cooker works and you can cut down the cook time for your daily meals enough to want to use it every time you cook.One of the best features of a pressure cooker is the ability to cut down the time that it takes for food to cook. The French designed it so that not only will heat cook food that is placed in the cooker, but the steam that is trapped in the machine will also cook the food. This causes the cooking time to be cut in about half because of the increase in heat and two methods that are used at the same time. This method is very fast and needs to be done safely so you must always be present when the food is cooking, unlike a set and leave crock pot where food is cooked slowly over a long period of time.The second way that you are able to get the most out of your cooker is by cutting down on the energy that is required to cook food. You will not have to use a high heat method, because the heat and steam will be working together. Because of the rate at which food will cook, the time and energy spent is also reduced making it an environmentally friendly option. While a pressure cooker might cost you more than a regular pan, you will end up saving money over years of use.The only way to get the most out of your pressure cooker is to use it as often as possible. When you know how to properly use your new kitchen tool, you can use it as often as possible.
What are the main uses for a freestanding gas cooker?

What are examples of specialized equipment used in the food industry and at home?
Could be anything, but my top five are the Microwave Oven, the can opener, the Toaster, the Pressure cooker and a food processor.
How do you cook tamales in a pressure cooker?
Pressure cookers can be dangerous. You have to make sure the seal (gasket) is in good condition and that the valve is working if you are using one you got secondhand. There should be instruction manuals for many pressure cookers on the Internet.Basically pressure cookers build up heat because they are sealed so well. They cook food much faster than a normal pot - You can cook a roast in about 20 minutes. They are also used frequently in canning veggies and other nonacidic foods.There is a pressure gauge on the top. You have to let the pressure go down before opening the pot! Please don't use one until you know what you are doing or your least problem will be a huge mess.First inspect the pressure cooker tharoughly and ensure that there are no damages especially to the gasket and see that it is clean.Next, you also need to ensure that the vent pipe is open and clear for pressure cooker with weighted pressure regulator. Check recipe for specific cooking method and cooking time. If your recipe requires a rack place it to the bottom of the cooker.Add a 1/2 cup water to pot if you're using a cooker that has a weighted system. Add 1 cup for pressure cooker that uses valve system. This should be sufficient for 20 minutes of cooking time.Place the food on rack.With the weighted system cooker remove the regulator then close and secure the lid. The cover handle should be parallel to the body handle. Place the cooker on heat.Once the steam begins to exit the vent pipe, replace the regulator. The weight on top the lid will begin to rock once the cooker reaches cooking pressure.The valve system cooker has markings on the cooker that indicate the pressure levels. Once the indicator is at 15 PSI the cooker is at the standard cooking pressure.Now, lower the heat once the cooker is at the cooking pressure in order to maintain the pressure. Comeback and chek and adjust the heat setting periodically.Use the timer to time the recipe.Once the required time is passed, you can turn off the heat.Next, you need to release the pressure inside by allowing it to reduce on its own.Once the pressure is released the lid can be opened after the removing the regulator.Hope this helps.
Why is it advisable to use pressure cooker at higher altitudes for cooking?
There are some simple facts that will help you understand this one. First, a general rule is that the hotter the source is, the faster heat is transferred into food, and the faster it will cook. (The trick is not to burn the food on the outside.) Second, water in an open cooking vessel cannot get hotter than its boiling point, and the boiling point of water at altitude is lower than it is at sea level. The pressure cooker allows the pressurized water to achieve a higher temperature than it otherwise could, and this makes the device more useful for high altitude cooking.
What is a sentence with the word pressure used as an adjective?
(*Here the noun pressure is not actually an adjective, but an attributive noun or noun adjunct.)When somebody is bleeding, apply a pressure pad to the wound.A pressure cooker is designed to cook food more quickly.
