A must-have in kitchen:the Food Blender
The blender has been and is a popular and kitchen appliance. Foods and liquids placed in it are
blended or chopped based on the speed set by the operator. Today's food blender can chop ice,
make peanut butter, grate cheese, heat soup, and perform many other useful functions.
The kitchen food blender is a motorized small appliance. A blade inside a jar is connected to a motor shaft. By varying current to the motor, the blade's speed is controlled.
Preventive maintenance can reduce the repairs needed to keep a food blender running for many years. The two most important steps an operator can take are not to overload the blender and to keep the seals tight.

ENGINE POWERThe more power in the engine, the more force is generated to the cutting blades. For kitchen stan-dard usage, pick a 1 - 1.5 horsepower machine.
NUMBER OF BLENDER SPEEDSAvailable models offer a range from a single speed up to 14 speeds. Just one or two speed blenders are very easy to operate and are often very du-rable.
CONTAINER MATERIAL AND CAPACITYBlender jars come in 3 types of materials, glass, plastic, and polycarbonate.
Glass blender jars are strong, can withstand a variety of tempera-tures, and are dish-washer safe, but can crack easily.
Plastic containers won't crack when you drop them, but they tend to be more diffi-cult to be cleaned.
Polycarbonate blender jars are sturdy, can handle extreme tem-peratures, and are dishwasher safe. But they are the most expensive type.
