FAQ Regarding Pressure Cooker
A pressure cooker might be profoundly damaged if there is too much water or too little water. There is a possibility of blocking off the valves due to too much food. Again if there is too little water, it might do some severe damage to the metal body of the cooker as well as the fittings also. There are some typical queries about the pressure cooker along with their answers are given below to keep the standard of the pressure cooker up to the mark.
What is the maximum capacity of a pressure cooker normally?
The highest capability of a pressure cooker varies according to the ingredients that are used to make them. We can make two of their classifications as the following:
- Maximum ½ full for foods like rice, grains, fruits and other dehydrated foods– These foods expand more during cooking with pressure and generate more foams. They also generate a lot of bubbles. With high pressure, these bubbles climb and spray out of the pressure cooker through the valves. So we should not fall more than half of these items during cooking.
- Maximum 2/3 full for other items- Other things like meat, stocks, soups, and vegetables generally don’t expand and climb. So, we can fill the pressure cooker up to 2/3 level during cooking these items.
What should people care about the maximum capacity of the pressure cooker they are using?
Maximum capacity is one of the most important safety features of the pressure cooker. This rating is enlisted on the manual to ensure the UL rating of the security. This maximum capacity is applicable for pressure cookers of all sizes, shapes, types and origins. The cause for maximum accidental incidents occurs during the usage of the pressure cookers is the unfamiliarity of the maximum capacity level of the pressure cooker. So, we should be aware of this fact.
How can we figure out the maximum capacity of the pressure cooker that we are using?
Unfortunately most of the times there is no rating on the pressure cooker of the maximum level of their capacity. For those cases, we should fill up the pressure cooker to get some visual feeling with water though it will not obvious to be precise enough. For some example, when the water is just under the attachment of the handle, it might be considered as 2/3 full.
How much rice, grains or beans we can cook with the pressure cooker?
People with less experience of using pressure cooker are mainly concerned about the amount of food items like rice, grains or beans that the pressure cooker can be able to hold up. It solely depends on the size of the pressure cooker. In fact, the amount increases proportionally with the increase in the size of the pressure cooker. For example, if we use 1-liter sized pot, it will contain 2/3 cups of dry rice or ¼ cups of dry beans. But if the size of the pot increases to 3 liters, about 2 cups of rice or 1¼ cups of bean can be accumulated there.
How might the minimum capacity of the pressure cooker be in general?
It is obvious that every pressure cooker needs a minimum level of water to make to operate. If the water is too less then it will damage the materials of the pot and the valves. So every manufacturer usually sets a minimum level of water requirement for the pressure cooker. This minimum capacity depends upon their size and the materials or types of the valve used. In normal sense, a larger sized pressure cooker needs more steam to be operated and for this similar purpose it also needs more water to be boiled up. Again where we normally use spring type valve needs a little amount of steam and also fewer water levels to lift up the valve.
Can we use something alternative liquid instead of water to reach the minimum level of liquid requirement of a pressure cooker?
We can use stock, fruit juice even wine or beer as an alternative liquid instead of the water. But we are not suggested to use any hard liquor. For example, we should not use alcohol as it will be evaporated, and the vapor caused by the boiling of the alcohol might also ignite. So it should be avoided strongly to use it in the pressure cooker.
What are standard and non-standard pressure cookers?
The standard of the pressure cooker indicates the maximum level of pressure at which it can operate successfully. There is no international organization for the setup of a global standard. In America normally “UL Rating” is normally authorized by American Appliance Testing and is used to refer the standard pressure rating of the pressure cooker. According to UL Rating, the standard pressure cookers use 15 psi of pressure or less than that. 15 psi is equal to about 103 kDa. Similarly in Europe people normally use “CE Rating” which indicates the average standard pressure above 0.5 bar to below 50 bars approximately.
How the cooking time is affected by the non-standard pressure?
The cooking time normally depends upon the thickness and density of the foods that are cooked. It needs to cook for more time for the foods that are denser, and thick food items will need more time in short pressure. Normally cooking time is larger for the non-standard pressure cookers but it will be smaller for the standard cookers.
What is the relation between the temperatures of the increase of the pressure cooker?
The pressure inside the pressure cooker increases with the increase of the temperature as their relation is proportional to each other. We will get the maximum temperature during cooking at a particular pressure level.
Is there any way to find out the pressure of a pressure cooker can reach?
The maximum level of pressure that a pressure cooker can normally reach is written on its body in the units of kPa, Psi or bar. There are some types of pressure we should keep in our mind:
- Operating pressure- It is the level of pressure that is used for the cooking of foods by the pressure cooker.
- Valve is releasing pressure- It is the pressure at which pressure releases from the valve out of the pressure cooker.
- Warping pressure- It is the level of pressure at which the components of the pressure cooker deforms normally.
This information might be written on the base for a stove top pressure cooker whereas the rating of valve release pressure is written on the valve or near about this.
