Definitions

  • the invention relates to a biscuit production method, in particular to a production assembly comprising the step of giving a decorative shape applied to the baked biscuit that travels in a conveyor.
  • Baked food products made of dough are generally obtained by mixing grain flours such as wheat or starch-based mixtures thereof and various excipients with water and subjecting to various processes in weight ratios according to a predetermined recipe to form a plastic shapeable dough.
  • an additional dough auxiliary body is usually provided the color of which is changed with a coloring agent such as cocoa, malt, and caramel and the auxiliary body having a different color is added to the biscuit dough by methods such as co-injection or like to form a pattern.
  • WO2018096420 discloses an apparatus for printing various graphical elements to the biscuit body by applying a food grade ink. Accordingly, a printing station having an edible ink print for example any type of letters, marks, numbers, etc. to the upper surface of a layer that completes the final appearance of a biscuit.
  • the biscuit is manufactured from a dough of two different colors. It is also disclosed that the biscuit body can be manufactured from different biscuit dough of different colors in a multi-layered structure.
  • NL1020104C2 discloses a method for preparing a baked product provided with letters, numbers, a logo, a decoration or similar marking baked in a cooking zone.
  • the method discloses the process steps of preparing, optionally raising the dough, portioning by measuring, optionally applying a filler and baking by placing a carrier such as conveyor or cooking tray that delivers it into an oven until a ready-made baked product emerges and marking via infrared laser by a laser marker.
  • the object of the invention is to rapidly apply a decorative pattern to the by-product cooked in the biscuit production process.
  • the invention relates to a biscuit production method, comprising a process step of supplying a biscuit piece cooked in an oven from an outlet of the oven to a carrier assembly.
  • the production method also comprises the process steps of resting of the hot stamp from a support wall the stamping temperature of which is selected between 150°C and 350°C against the biscuit piece whose the outer periphery temperature in an outer periphery is set to a value between 40-200°C on the carrier assembly in a forming position until a crispy region is formed; disconnecting the support wall from the outer periphery, and cooling the biscuit piece. It is possible to apply rapidly a desired crispy region form onto the biscuit with the hot stamp resting against the biscuit piece came out of the oven.
  • the crispy region is obtained by removing the moisture at the part that the hot support wall rests against and increasing the porous structure locally in the outer periphery of the biscuit piece.
  • the stamping temperature is selected close to the upper values of the range, it is detected that darkening occurs in the crispy region such that a mark is made. At lower ranges, the color differences are too low to be perceived visually.
  • the temperature of the support wall is selected between 150 and 200°C and the forming position is taken when the temperature of the outer periphery falls between 80°C-150°C after the oven outlet of the biscuit piece.
  • the temperature of the outer periphery of the biscuit piece has not yet reach the room temperature, when forming application is mad to the outer periphery at a stamping temperature selected higher than the temperature of the outer periphery, it is surprisingly detected that the crispy region reduces the cracks at the region applied in the outer periphery of the biscuit. This reduces the wastage that may occur, especially when giving a plastic shape to the biscuit after baking.
  • the circumferential wall delimiting the support wall applies a pressure at the outer periphery of the biscuit piece so as to form a neck.
  • the moisture ratio of the biscuit piece at this stage is kept more than 5%.
  • the opening in the form of ring of the circumferential wall whose diameter is narrower than the biscuit piece ensures that the biscuit piece plastically deform by extending to both sides along the opening so as to give neck inwards and surround from the outwards.
  • a preferred embodiment of the invention comprises the process steps of fitting of the outer edge to the outer periphery so as to apply pressure with being arranged in a ring form and forming an outer frame circumferentially delimiting the top part.
  • the stepped outer frame prevents the top part from breaking or cracking from the edges as part of the hardened part.
  • a ring-shaped chamber whose base is the outer frame can be obtained.
  • a preferred embodiment of the invention comprises the process step of applying an edible filler onto the outer frame by a depositor.
  • the stepped outer frame allows the filler to circumferentially surround the top part. Further, due to the fact that the stepped outer frame is part of the crispy region, thermal stress-induced micro-cracking due to thermal differences during the application of the filler is prevented.
  • a preferred embodiment of the invention comprises the process step of heating the support wall to the stamping temperature before the forming position via a electric heating element adapted on the hot stamp. In this way, it is possible to adjust the support wall in a controlled way in the mark forming position to a predetermined temperature range. Energy losses are reduced.
  • support wall comprises a projection extending to face the periphery of the biscuit and in the forming position, the projection applies pressure to the outer periphery so as to form a cavity of the crispy region when the biscuit piece rests against the outer periphery.
  • the cavity is formed without cracking since it is heated at the same time while the outer periphery is shaped by pressure and has a reinforced wall in the biscuit piece as a part of the crispy region.
  • an edible filler preferably containing chocolate is filled into the cavity by a depositor.
  • the hardened part of the cavity has a smaller porosity than the other part of the outer wall and prevents micro-cracks in the wall due to thermal differences when the edible filling falls on the hot biscuit wall and shortening the shelf life of the biscuit piece by absorbing the oil or moisture contained in the filling over time.
  • a preferred embodiment of the invention comprises the process steps of providing the biscuit piece on a conveyor belt advancing at the outlet of the oven and advancing the hot stamp in a relative movement by a lifting arm so as to apply vertical pressure to the top part in correspondence with the horizontal advancing movement of the biscuit piece.
  • an edible filling is trapped inside the biscuit piece and the outer periphery edges are arranged in a rounded disc-like form.
  • biscuits having such forms are produced with known biscuit dough recipes, they may form wastage by cracking and breaking on the edges during transportation and packaging. However, it is made possible to prevent breakages by for example, strengthening the edges by forming a ring form close to the outer edges of the biscuit pieces.
  • the invention includes a biscuit production assembly, comprising an oven cooking a biscuit piece and a conveyor belt carrying the cooked biscuit piece supplied from an outlet of the oven.
  • the biscuit production assembly also comprises a support wall provided on the conveyor belt; a projection extending from inside of the support wall to outwards; and a hot stamp having a electric heating element adapted to the support wall so as to heat the projection to a stamping temperature between 150°C and 350°C, preferably 180°C.
  • the hot stamp applies thermal treatment by resting against the outer periphery from the top part of the biscuit piece at the outlet of the oven and a line is formed on the heated biscuit wall, which is visually different from the other parts and strengthened so as to increase the structural strength by reducing the crystal structure in a way that can create a moisture and oil barrier.
  • a preferred embodiment of the invention comprises a depositor which is provided on the conveyor belt at a distance from the hot stamp and arranged to apply an edible filler containing chocolate to the biscuit piece from the top part.
  • Depositor ensures that final product includes two different components by applying an oil based filler, for example chocolate to the region that the hot stamp strengthened by the hot stamp with resting against the outer periphery.
  • Figure 1 is a schematic view of a representative embodiment of the biscuit production method according to the invention.
  • Figure 2 is a perspective view of a representative embodiment of a biscuit having a thermal print mark, which is produced by the method according to the invention.

  • a flat and ring-shaped inner rim (27) abutting against the circumferential edge (25) fits to the flat face of the support wall (24) at a distance surrounding the projection (23).
  • a lifting arm (26) in the form of a flat bar carries from its lower end the support wall (24) by rising vertically from its opposite face.
  • the lifting arm (26) is at the end of a robot arm (not show) and carries the support wall (24) such that it follows the spacer (41) thereon with which it is aligned by making a relative movement according to the speed of the conveyor belt (52).
  • An electrical electric heating element (21) is adapted to the hot stamp (20) so as to raise the stamping temperature (T d ) of the metal support wall (24) to 180°.
  • a lifting arm (26) in a forming position abuts against the biscuit piece (40) to apply a force providing a plastic deformation from the top part (44) by travelling with a first relative speed (v1) both forward such that it follows the biscuit piece (40) and towards a outer periphery (42) in a downstream direction.
  • This force is selected as 0.1 N.
  • the electric heating element (21) heats the hot stamp (20) and the hot stamp (20) provides a pressure with a pre-stress from the circumferential edge (28) to the top part (44).
  • the top part (44) is significantly filled to the support wall (24) by means of the plastic deformation from the outer periphery (42) by providing a neck (35), until it contacts with the inner rim (27).
  • the lifting arm (26) travels with a much lower speed that the speed of approaching to the biscuit piece (40).
  • having a crack on the outer periphery (42) is provided by arranging the support wall (24) approximately 80-100°C warmer than the biscuit piece (40).
  • Hot stamp (20) with a temperature set to 180°C applies high temperature from the outer edge (25) to the top part (44) by the projection (23) and the circumferential edge (28).
  • the biscuit piece (40) both minimizes the porous structure by reducing the moisture and deforms by means of the Maillard reaction in the parts to which high temperature is applied, due to the high sugar contents that it contains and it forms a crispy region (30) having a higher resistance to breakage.
  • the crispy region (30) includes a ring structure with two steps formed by the joining of an outer rim (34) and an inner rim (34) coaxial therewith and having a narrow diameter with the neck (35), and a cavity (32) the depth of which is created by projection (23) entering inwards at the center of the top part (44).
  • the crispy region (30) that the hot stamp (20) creates on the biscuit piece (40) is seen in perspective.
  • the cavity (32) is a depression formed by the projection (23) at the top part (44) in the form of a rounded star.
  • the cavity (32) is surrounded by both the inner rim (36) and the adjacent concentric outer rim (34) in a ring form at a radial distance.
  • a base (46) of the biscuit piece (40) is in a planar form such that it provides a fixed placement on the conveyor belt (52).
  • the hot stamp (20) applies heat to the biscuit piece (40) until it forms the crispy region from the contacting parts by means of the electric heating element (21), by being placed on the top part (44).
  • the hot stamp (20) is applied onto the top part (44) with a stamping temperature (Td) of 180°C for 5 seconds.
  • the lifting arm (26) travels at the first relative speed (v1) both in the downward direction and in the travelling direction of the conveyor belt (52) and thus the production continues on the moving conveyor belt (52) without interruption.
  • the hot stamp (20) differentiates from the support wall (24) by browning the outer periphery (42) with which it contacts.
  • a pressure can be applied onto the biscuit pieces (40) on a tray or conveyor belt (52) only by means of the up and down movement of the lifting arm (26) without sliding to any side.
  • the lifting arm (26) lifts the hot stamp (20) over the biscuit piece (40) by means of a forward and upward movement at a second relative speed (v2). With this, the biscuit piece (40) is cooled to a filling temperature between 40-80°C on the conveyor belt (52). Subsequently, a depositor (60) positioned on the upper part of the conveyor belt (52) and comprising a filler (62) made of hot chocolate covers the crispy regions (30) with the filler (62). The crispy region (30) prevents the cracking against the thermal stresses provided by the depositor (60) and created by the temperature difference between the outer periphery (42) and the filler (62) of different temperatures.
  • the depositor (60) forms a middle part (64) of the filler (62) by completely filling the cavity (32).
  • the depositor (60) aligned with the outer rim (34) forms a circular edge part (66) of the filler (62).
  • the cooled filler (62) solidifies and is fixed on the outer periphery (42).
