Deciding Which Food Processor To Buy

Are you considering purchasing a food processor? If so, there are a number of things to keep in mind when you make that purchase. Type and cost are probably two of the more important factors that you’ll most likely weight your decision on, but there are other factors like added features, and capacity. The food processor that you buy will be used on a regular basis and can help you achieve great results, but if you don’t buy the one that best fits your needs, chances are you are not going to use to it’s full capabilities.

The biggest decision you’ll have to make when buying a food processor is what type of food processor is best for you. There are a number of different types of processors available on the market including manual, electric, mini, commercial, and baby food processors. Each type has it’s own unique features and functionalities that provide valuable input to your overall process of cooking, but not all of these types may be practical for you depending on what type of goals you are looking to accomplish with your food processor.

If you’re simply looking to chop up a few items for a quick meal and don’t really plan on doing much more than this, then perhaps you may want to consider purchasing a manual processor. These types of processors are capable of shredding, slicing, and chopping vegetables, nuts, and fruits with little physical labor required on your part. You are required to do the work by turning the crank on the processor, but it usually isn’t very time consuming and can be done in a few minutes or less. Manual processors are cheaper in most cases so if you’re also looking to save a little money, this would be your better option.

Chances are you may want to use your processor on a regular basis and purchasing a manual processor may not be the best idea since you might get tired of constantly having to crank the processor. In this situation, an electric food processor may be your better option since all you have to do is press a button and the work is done for you. Because these types of processors are motorized, they are able to shred, slice, and chop vegetables, fruits, and nuts more quickly and more finely than manual processors. This type of food processor is generally a little more expensive than the manual processor, but it processors much more food in a shorter amount of time.

If you’re looking to buy a food processor it’s important that you consider what your intentions are as far as food output goes. If you’re looking to process larger amounts of food on a consistent basis, then you may want to consider buying a more advanced processor that can provide the output that you’re looking for. Otherwise, if you’re simply looking to process food on occasion for a quick meal, then you would probably want to consider downgrading to a less expensive processor that is perfectly capable of handling the task for you. Either way, you’re sure to enjoy the many benefits that food processors have to offer.

Physics Question - Electric Food Steamer?

An electric steamer works in the following way. Add water to the lower compartment, and the steamer changes water to steam. The steam rises through the holes in the base of the food compartment and the food will be steamed.

Broccoli and fish needs 600 kJ to be steamed. The power rating of the steamer is 800 W and specific latent heat of vaporisation is 2.3 x 10^6 J/kg.

a) Calculate the time required for steam the broccoli and fish after the water has reached 100°C.

b) Calculate the mass of water that has been converted to steam during this period of time.

c) Do you think the food will cook faster if it is placed in boiling water instead of using the steaming method? Explain.

d) John commented that the part of the fish near the bottom of the food compartment might be over cooked while the upper part might not be cooked enough. What would you say to him?

Thanks in advance.

a)
1 W = 1 J/s , 600 kJ = 600000 J
The time required = 600000 J / 800 (J / s) = 750 s = 12.5 mins
b)
The mass of water = 600000 J / 2300000 (J/kg) = 0.261 kg
c)
The food will cook slower if it is placed in boiling wate, because the heat transfer rate is better in steamer than in boiling water.
As the steam is condensed, more heat is released due to the latent heat.
d)
It depends on the design of the steamer.
Usually it is thermal homogeneous in a steaming steamer.
