The idea of combining the functions of various kitchen devices first appeared almost 100 years ago. The American Troy Metal Products company first proposed a prototype of such a device in 1919. Unfortunately, this model was cumbersome, difficult to use and very expensive. Its cost was about $ 200 that was very expensive.
The wide popularity of food processors began in the 70s and remains high for more than 50 years. These models were able to provide high enough efficiency at an affordable price.
Models with functions of a blender, mixer, meat grinder, juicer, etc., usually are classified as a food processor. But today, the functionality of kitchen appliances varies in a wide range. Many separate modern devices often provide advanced functionality due to additional attachments and accessories. They can also qualify as a food processor with limited capabilities. Correct classification of modern kitchen appliances depends on the features of the food processors.
Of course, a choice of optimal food processor primarily depends on its price, functionality and technical characteristics.
The main characteristics.
1. The bowl capacity.
This parameter is one of the main. It directly affects the amount of foods and the dimensions of model.
Choice of bowl capacity depends on the number of family members and required functions.
Modern models have bowls with a capacity from 1 to 7 liters (4 – 30 cup).
Usually, companies indicate an overall volume of bowl. But this value is different from its maximum filling that depends on density and type of foods. For example, the bowl with total volume of 1.5 liters can accommodate about 5 lb of dry products, or 1.5 liters of liquids or 750 grams dough.
Processing a small amount of food in a large bowl is not very convenient and is uneconomical. This aspect is important when choosing the bowl capacity.
The bowl up to 1 liter is well suitable for cooking omelet on 1-3 people.
Bowl with average size from 1 to 3 liters is enough for kneading dough. This capacity is suitable for family of 2-4 people.
The bowls with capacity from 3 liters or more are considered large.
Very often, the bowl has a grading in grams, milliliters, cups or ounces for convenient adding the required amount of ingredients.
1.5-1.7 liters is the most common volume of jar in a blender.
Motor power directly depends by the bowl volume and, accordingly, the amount of processed foods. The following ratios of power and volume are considered optimal: 300 W – 1.5 liters; 400 W – 2 liters; 700W – 3 liters.
The processing duration also depends on the power. Of course, a more powerful model works faster.
Power of compact models is typically about 300 – 400 W, the models of average class have 400-600 W, powerful models provide from 700 to 2000 W.
Number of speeds in modern models varies from 1 to 25. Adjustment of rotation speed is intended for selection of optimal intensity. Speed control is carried out stepwise or smoothly.
Specific speeds comply to different operation modes, eg, function of meat grinder, juicer, blender, etc. This information is indicated in the instructions or on the housing.
Usually, higher speeds are used for crushing food, and low speed – for mixing.
Number of speeds in manual mixer varies from 3 to 9. Some stationary mixers have 16 speeds. Number of speeds affects the cost of model. But as practice shows, only 3-4 speeds are the most popular for everyday use.
Some models have icons-tips for selecting the optimum rotation speed.
Maximum rotating speed reaches 22000 rev / min in modern models. The high rotation speed provides effective and fast shredding the solid foods.
The housing is made of plastic or stainless steel. Plastic is used much more often. This material is an inexpensive, light and fairly durable. Usually, plastic models are available in a wide range of colors.
The housing of expensive models is often made of brushed or polished stainless steel. Matte surface does not retain fingerprints or drops of liquid products what simplifies the care.
Stylish design and durability are main advantages of stainless steel.
The bowl is made of plastic, glass or stainless steel.
Durable transparent plastic is very convenient for visual control. Plastic bowl is lightweight, durable enough and relatively cheap. But plastic is sensitive to mechanical influences.
Glass bowl is mainly used in expensive models. They are made of heat resistant thick glass. Low resistance to shocks is a major disadvantage of such bowls.
Expensive models with elegant design sometimes use bowls of stainless steel or aluminum alloy. They are much more durable and hygienic and have a stylish design. High cost is the main disadvantage of such bowls.
Many models have the compartments in housing for accessories and power cord. The cord length typically varies from 25 to 60 inches. Practice shows that the convenient length is 35 inches and more.
Preset cooking programs.
Many modern models are equipped with the preset programs that provide automation of the cooking process. This video demonstrates the operation of the model with 5 pre-programmed auto menu.
