Definitions
- the invention relates to a Cartesian-type three-dimensional (3D) printing device for a food product, as well as an assembly comprising said device and a device allowing solidification of the food product.
- the invention also relates to a method for additive manufacturing of a food product using the assembly according to the invention.
- the invention relates to the field of 3D food printing devices.
- 3D printing consists of manufacturing the final part layer by layer, by aggregating the material using various processes, only where the digital model predicts it.
- 3D printing technologies aggregate their base material by different processes: bonding, polymerization of a monomer powder, selective laser sintering, fusion by the use of an electric arc, etc. They were firstly developed for polymers (resins, plastics) and for metals.
- 3D printing technologies were then transposed to the food industry, using deposition methods by extrusion, by ink jet, by binder projection or even by selective laser sintering. These first three types are today used commercially in the manufacture of food products based on chocolate, meat, fish, fruits, vegetables, or even cereals...
- the Applicant has developed a Cartesian-type 3D food printing device responding to this technical problem, and allowing increased productivity, obtaining food products of any shape, to taste. and with a controlled texture, with an aesthetic similar to traditional processes, and easily cleanable.
- Patent document US 2017/0251713 A1 describes a 3D food printer provided with a removable printing plate in which a piece of food is manufactured. A material (paste) is extradited from a print head and then injected through the print head into a plate. To do this, the plate is placed below the print head and receives the food paste extruded by the print head.
- the 3D food printer also includes a vibration device acting on the printing plate in order to level the material.
- a disadvantage of such a 3D food printer is that it imposes limitations in terms of geometry of the injected viscous materials and deposition speed.
- another disadvantage of the 3D printer described in this document is that it requires the addition of additives in the manufactured food product.
- the 3D food printing device thus aims to take advantage of such a process, while improving the flow of the matrix as well as the reparability and density of the powder, and by reducing the mechanical forces on the head. printing.
- the 3D food printing device further aims to obtain food products manufactured by 3D printing without using additives and without altering the taste and texture of the food products produced.
- the present invention aims to resolve all or part of the disadvantages of the state of the art cited above.
- the invention relates to a Cartesian-type 3D food printing device.
- said Cartesian-type 3D food printing device comprises: a. a removable print tray; b. a print head positioned opposite the printing tray and capable of extruding pasta, said print head moving along two orthogonal axes; vs. a printing plate configured to allow movement of the print head along a third axis orthogonal to the other two axes; d. a powder or food gel supply system configured to allow sequential or regular filling of the printing tray with said powder or said food gel, said powder or said food gel deposited in the printing tray constituting a matrix; summer. a vibration system connected to the printing tray, making it possible to vibrate said matrix in said printing tray.
- the sequential or regular filling of the printing tray carried out by the food powder or gel supply system is created in order to maintain a constant height of powder or gel of between 1 and 20 cm to constitute the matrix and thus maintain a height (level of the matrix) above the printing area, and this layer after layer.
- This system is necessary because the forces created on the print head increase with the quantity of powder or gel in which the head is immersed.
- Sequential filling following the print height allows you to maintain a quantity of powder or gel necessary for the self-repair of the matrix while limiting the forces exerted on the print head.
- Such sequential filling also makes it possible to guarantee that the material injected into the matrix is always in suspension therein.
- the printing tray is kept static while the print head is moving, so as to avoid the maximum amount of movement and potential offset between each printed layer.
- the print head is capable of extruding food pastes having a viscosity of between 10 -1 mPa.s and 10 7 mPa.s.
