Buying a blender: which design and features are right for your household?

A blender should finely purée smoothies, process soups and sauces, or chop ingredients. In practice, however, unsuitable purchases are often caused not by insufficient wattage, but by an unsuitable design, containers that are too small or components that are difficult to clean. Before buying, it is therefore worth considering how you will actually use the appliance.

Common blender buying pitfalls

1. Wattage is equated with actual performance

A high wattage initially describes the appliance’s electrical power consumption. On its own, it does not indicate how evenly the appliance blends or how well the blades, container shape and motor control work together. For frozen fruit or ice, the blade geometry, a suitable pulse function and the operating time permitted by the manufacturer are also important.

2. Capacity is misjudged

The container size does not always correspond to the maximum usable liquid capacity. For example, the container supplied with the Ninja Professional Blender holds 2.1 litres, but the stated maximum liquid capacity is 1.9 litres. A 0.6-litre blending cup is also better suited to a single serving than to a family household.

3. Cleaning and material specifications are overlooked

Permanently fitted blades or difficult-to-reach joins can make cleaning more challenging. So look for removable parts, clear information about dishwasher suitability and food-safe materials. The description BPA-free blender should refer to the components that come into contact with food, rather than being applied indiscriminately to the entire appliance.

The most important criteria when buying a blender

Jug blender, hand blender or personal blender?

The design should suit how you intend to use it:

• Jug blender: Suitable for larger quantities, smoothies and frozen ingredients, and depending on the model, a blender with an ice-crushing function. The container sits on a motor base, which requires more worktop space.
• Hand blender: A hand blender can be used directly in a saucepan or a suitable container. This is practical for soups, sauces, purées and baby food. Accessories such as a whisk or chopper expand its versatility.
• Personal blender: A personal blender or smoothie maker usually works with a smaller cup, which can sometimes be used directly as a drinking container. This is ideal for single servings, commutes and smaller kitchens.
• Hand mixer: A classic hand mixer with beaters is primarily designed for dough, cream and whisking egg whites. A model with an additional blending attachment is more versatile, but does not automatically replace a large jug blender.

Motor, speeds and operating time

Do not compare wattage alone. The following are also relevant:

1. Speed settings: Several settings allow you to adapt the appliance more precisely to soft fruit, nuts, sauces or coarse mixtures.
2. Pulse or turbo function: Short bursts can be useful when chopping ingredients and crushing ice.
3. Operating limits: According to the product information, some models must not be run for more than 60 seconds at a time. If you are blending several batches, allow breaks for the motor to cool down.
4. Safety lock: The appliance should only operate when the container and attachment are correctly secured.

Blades, containers and cleaning

Stainless-steel blades are common among the models mentioned. What matters is whether they are approved for the intended use. Ice, hard ingredients and dry foods should only be processed if this is permitted in the instruction manual.

Dishwasher-safe parts are helpful when it comes to cleaning. The motor unit, cable and plug must never be immersed in water. Sharp blades should only be handled by the designated plastic or holder section.

Hot food requires particular care: not every kitchen blender is suitable for boiling liquids. The Ninja Professional Blender and the nutribullet Pro specifically warn against hot liquids. Before preparing soup, therefore, check the temperature limit for the model in question.

Practical tips for safe operation

• Cut larger ingredients into smaller pieces before blending and observe the maximum fill mark.
• When using a personal blender, add liquid according to the instruction manual before adding hard or frozen ingredients.
• For hot food, only use a model whose instructions explicitly permit it.
• Unplug the appliance before changing attachments, cleaning it or removing the blades.
• Clean removable parts as soon as possible after use and only wipe the motor unit with a damp cloth.
• Keep blades, cables and small parts away from children.

Frequently asked questions about blenders

Which blender is suitable for smoothies?

For single servings, a smoothie blender or personal blender with a drinking cup is practical. For several people, a jug blender with at least around 1.2 to 1.5 litres offers more flexibility. For frozen fruit or ice, look specifically for a stated ice-crushing function.

Can you purée soup with a hand blender?

A hand blender is generally suitable for soups and sauces, provided the model and the container being used are designed for this purpose. With hot liquids, temperature limits and splash protection must be observed. The blending shaft should be immersed deeply enough to reduce splashing.

How much electricity does a blender use?

Consumption depends on the power rating in watts and the actual operating time. A 1000 W appliance running for one minute uses approximately 0.017 kWh in theory. Short blending intervals, suitable portion sizes and breaks can reduce both consumption and strain on the motor.
