The invention relates to a device and a method for mixing material to be mixed. The invention especially concerns the mixing of food products and, in the area of food products, especially drinkable food products.
There are many areas which are concerned with the mixing of materials to be mixed. The following primarily concerns the field of food products, although the invention can also be applied to numerous other areas.
There are mixers, blenders and other means to allow the mixing of food products and ingredients in the private household and in professional kitchens when necessary. The preparation of salad sauces is mentioned as an example. The liquid and solid ingredients are frequently added to a mixing container which can be sealed by a lid. The components are mixed with each other by shaking. In order to improve the thorough mixing, there are containers whose lid contains a fixed rod assembly which protrudes into the interior of the container and promotes the thorough mixing. Mixing containers are also known which comprise a mixing mechanism which is integrated in the lid and can be moved by cranking a hand knob on the upper side of the lid. Such containers typically comprise a spout so that the lid need not be removed.
The preparation of a mixing material 1 to be mixed by means of a stirring staff 2 is shown by reference to
Better mixing results are achieved in that solutions are used which allow overhead mixing. An approach is designated in this case as overhead mixing in which the mixing mechanism 5 is situated at the bottom in a mixing container 6 and in which the mixing material 1 is situated above the mixing mechanism 5.
One example of a typical kitchen mixer 10 which allows overhead mixing is shown in
The cap 8, which accommodates the mixing mechanism 5, is frequently composed of several components which are difficult to mount and dismount. The amount of cleaning work is often very high because it is also necessary to clean the mixing container 6 and the lid 9.
There are also other approaches which allow overhead mixing. Such an approach is illustrated in
The cleaning effort is also high in this solution because the mixing container 6, the lid 15 and the plastic element 16 need to be cleaned.
It is a disadvantage of the known solutions that a number of special parts or appliances is necessary. Aspects such as functionality, variability and flexibility play a major role in the field of food products in particular. It is further important that such appliances should offer easy and complete dismounting capabilities in order to meet the highest possible demands concerning hygiene. It is a further problem of such appliances that they are used especially in kitchens and public areas by several users. Ingredients can thus mingle with each other in an undesirable manner.
It is therefore the object of the invention to provide a simpler approach for mixing, mingling, stirring and even crushing or chopping ingredients or other mixing materials. The respective means shall offer universal use to the highest possible extent and still offer sufficient hygiene for each user.
According to the invention, a completely new approach is used, which is based on the fact that a device with a cup such as a conventional drinking cup is used which comprises only one single (drinking) opening.
Said cup is surrounded by a jacket, which is provided among other things to stabilise the cup. A mixing mechanism is introduced in such a way that the mixing mechanism protrudes into the interior space of the cup, wherein the mixing mechanism is connected to a drive unit or the mixing mechanism can be connected to a drive unit in a separate (e.g. subsequent) step. The mixing mechanism is then rotatably driven by the drive unit in order to provide a mixing material by mixing from an initial filling, which mixing material can be drunk or eaten for example. The mixing mechanism is taken from the interior space of the cup and the cup is separated from the jacket. The cup plus the mixing material disposed in the interior is now ready for consumption.
This approach offers a complete release of the cup for the first time in that the initial filling is provided and the mixing material is offered for consumption after the mixing.
The invention allows for the first time that the customers bring their own cup or purchase a cup with an initial filling for example in order to have it mixed in a special device. The mixing material only comes into contact the interior of the cup and the mixing mechanism.
The invention allows offering completely new business schemes for the first time.
A mixing mechanism which is (fixedly) integrated in a lid is preferably provided in all embodiments. During the introduction of the mixing mechanism into the interior space of the cup, the lid can be used for closing and/or fixing the opening of the cup. The device further comprises a drive device with a receiving region (connecting region) which is formed in such a way that the cup plus jacket and mixing mechanism can be attached to or placed on the receiving region. The stirring mechanism is drivingly connected (preferably in a friction-locked manner) to the drive device during the attachment or placement. When the drive device is activated, it makes the mixing mechanism rotate through the lid. The rotation of the mixing mechanism produces the mixing or mingling of the initial filling which is situated in the interior of the cup.
The device in accordance with the invention allows a large number of new applications which will gain in importance especially in the field of nutrition.
The device in accordance with the invention can be used flexibly and can be cleaned easily.
In accordance with the invention, disposable cups (cups for one-time use) or even thin-walled, film-bag-like cups can be used.
This solution avoids the usual washing of many individual parts of the device that are often difficult to access. Furthermore, the decanting of mixing material for storage or further processing can be avoided because the mixing material is provided in situ, i.e. directly in the cup. The mixing material can be produced, stored and transported in an entirely hygienic manner. Depending on the configuration, no third party has access to the mixing material, which can be relevant especially in the area of high-performance sports and in the professional sports area.
The device in accordance with the invention is especially suitable as a beverage mixer.
The device in accordance with the invention can also be used for example as a kitchen and restaurant application for producing soups, sauces, beverages, shakes, dips, soft drinks etc.
The device in accordance with the invention can be used in the field of sports for preparing fitness drinks, fitness cocktails, fruit juices, power food for athletes etc.
The invention is also suitable for providing baby foods and liquid foods in the hospital area, retirement homes and the like.
New and innovative possibilities for meals are provided by simple handling and by the fact that there are only very few basic elements.
The invention can also be used in other areas where the rapid and easy mixing of components is concerned. The mixing of multicomponent substances such as adhesive or colour substances and the mixing of medications or food supplements must be mentioned in particular.
Further details and advantages of the invention will be described below by reference to embodiments and the drawings.
