DETAILED DESCRIPTION OF THE INVENTION
In Fig. 1 a kitchen appliance, especially a food printer (1) according to the invention is shown. The food printer (1) comprises a housing (10) with an opening (11) for printable food and binder. The housing also comprises an interface, in Fig. 1 shown as a touch display (12), preferably an OLED display. Close to the opening there is also a RFID scanner (13) for identifying the printable food and the receipt if food with RFID tags are used.
The housing (10) also comprises at least one reservoir, preferably more, for the different kinds of printable food that is used, and at least one reservoir, preferably at least two, for the binder. In the embodiment shown in Fig. 1 several reservoir are shown in the form of pipes (16). All the reservoirs are connected to the printer arm (21) and the printer head (22). The reservoirs are filled with printable food and binder through the opening (11).
The housing (10) also comprises a printer arm (21) with a printer head (22), control unit (23), battery (14) and/or a power connection (not shown). The food printer also comprises a network connection, preferably a Wi-Fi connection (15) to the internet for downloading receipt or program updates. The printer head (22), printer arm (21) and control unit (23) is part of a Computer Numerical Control (CNC) food printer. The control unit (23) controls the movement of the printer arm and head as well as controlling what kind of drop the printer head should produce in every moment to create the decided shape or form.
For cleaning and charging the housing (10) is connected to a base unit (50). The base unit comprises a cleaning system (51) for cleaning the printer head (22), power supply (52), and contacts (53) for recharging the batteries (14) in the housing (10).
Fig. 2 shows the housing (10) connected to the base unit (50). This could be done for charging the batteries (14), cleaning the printer head (22), or for storing.
Fig. 3 shows the food printer in use. The housing is disconnected from the base unit and arranged over a plate (100) on which the food is printed. Next to the food printer (close up in Fig. 3a) there are plates (100) with different kinds of printed food, e.g. printed food with a 3D-structure (101), printed food with enclosures (102), printed food with textures (103), and a food printed as a 3D pattern (104).
In Fig 4 the method of printing food is schematically shown. The printer head (22) prints a small drop (31 , 32, 33) of the printable food or binder from the reservoirs. The small drops, one by one leaves the printer head (22) at the same time as the printer head moves. In this way layers on layers can be created and a 3-dimentional shape (or 2 dimensional shape) is built. The amount, spreading and ration between the binder and the printable food at the time, controls the level of stableness of the printed food.
Most kinds of food is possible to us as printable food as long as it is possible to have it in a form suitable to be printed by a printer head, e.g. preferably in a liquid state or close to a liquid state, like gel. As binder gelatine, gluten or sugar can be used. In the embodiment shown alginic acid, a substance extracted from brown algae, in combination with calcium is used. Alginic acid is used in cooking today and is preferred for its simple and abrupt gelation in contact with calcium. In Fig 2 the use of aginic acid (31), calcium (32) and food (33) is shown. The amount, the spreading and the ratio between algin, calcium and the main substance printed at the time, controls the level of stableness of the printed food. It is possible to use different kinds of printable food at the same time.
The housing (10) is primarily made of polycarbonate. The material is applied in three different variations, each providing the right characteristics for the different parts. Transparent polycarbonate is used for the window, black tinted for the lid/display, and white for the body. The robotic printer arm and head is made from aluminum. A blue (O)LED backlight accentuates the processes inside the printer.
The invention is a handy CNC food printer for kitchens from professional to domestic. It autonomously prepares basic and otherwise difficult to create 2- and 3-dimensional parts of meals. It works with a layer-by-layer printing process out of small particles from diverse ingredients.
For beginners and for easy usability of the invention some basic printable food is preferably available in blister packs from the supermarkets. The blister pack comprises the exact amount of ingredients needed and the digital printing instructions, the recipe, for the printer. This is preferably provided in the form of an RFID-chip on the blister pack. For advanced users there is also the possibility to create own recipes or download from other professional users, user groups, or food manufacturers.
The inventin relates to a kitchen appliance, especially a food printer for making 2- or 3-dimentional shapes comprising a housing (10), an opening (11) for printable food (33) and binder (31 , 32), a control unit (23), and a printer head (22), wherein the printer head (22) prints small drops of the printable food (33) and the binder (31 , 32) while moving to build the 2- or 3-dimentional shape. The stableness of the printed food is controlled by the amount, spreading and/or the ration between the binder (31 ,32) and the food (33). The housing comprises at least one reservoir for printable food, and at least one reservoir for the binder. Alginic acid and calcium is used as binder. The housing comprises an interface, preferably comprising a touch screen (12). The housing comprises a rechargeable battery (14) and preferably contacts (16) to recharge the battery.
