Definitions

  • the invention relates to a wafer machine for production of relatively small series of wafers, rather one at a time, given a command from a user or the personnel at a point of purchase.
  • a point of purchase may be a kiosk, a gas station, or a traffic terminal.
  • Wafers are typically fresh goods and provide a most crispy crust when being newly fried and appear to have the best quality at that time. Wafers loose quality relatively rapidly and loose their crispiness of the crust, and become soft and sticky.
  • the unpredictable production rate might suggest that one may prepare wafer mixture of sufficently large volume to meet the peak demand, but problems would arise if the expected demand should not occur, because one would have to store unused wafer mixture for a relatively long time so the quality of the stored wafer mixture would decrease to such a degree that a desired quality (with respect to taste, crust, flavour and hygiene) of the wafers then produced, may not be achieved, or in which unused wafer mixture must be frozen to avoid undesired bacterial growth in the mixture or in which unused mixture simply has to be poured out at the end of the day.
  • a waste problem may also arise when pouring out unused wafer mixture due to the risk of blocking the outlet pipe.
  • Prior art in the field For catering production-ready wafer mixture may be delivered as frozen blocks. Such wafer mixture blocks must be taken out the day before use. Such frozen blocks have the disadvantage that they require freeze refrigeration during transport and frozen storage in the users catering kitchen. Moreover condensation on the frozen block due to humidity in the air will occur if it is unpacked during melting, and the mixture becomes undesiredly watered out.
  • Norwegian patent 314381 "Machine for automatic production and purchase of water based on prepared raw materials" and belonging to the applicant, comprises a powder container for dry wafer powder and a powder volume measurement device for delivering dry wafer powder to a mixing container using a control unit, and a valve for liquids or a pump for provision of a liquid to the mixing container, and a stirring mechanism for mixing the dry wafer powder and the fluid to a wafer mixture.
  • NO31 381 does not solve the requirement for a sufficiently precise measurement of dry wafer powder and liquid to a wafer mixture.
  • NO314381 does not solve the problem arising after each preparation and discharge of wafer mixture in that remains must be removed and the mixing container and the whisk must be thoroughly cleaned to maintain hygienic conditions in the apparatus.
  • an apparatus as defined in the attached patent claims, in which said apparatus is arranged for producing one or more wafers and in which said apparatus comprises a wafer iron having an upper and a lower frying plate with heat elements, and an actuating device arranged for opening the wafer iron for adding wafer mixture and for adding the batch of wafer mixture to the wafer iron in order to fry the wafer mixture into a produced wafer, thereafter to open the wafer iron to remove the produced wafer, with a batch preparation container arranged for receiving wafer powder comprising dry wafer powder with flour and other dried ingredients from a powder container, and liquid added from a liquid line (14) in which the invention is characterized by the following features: that the batch preparation container is arranged on a weighing cell for measuring of a desired mass comprising dry wafer powder and liquid for mixing of the wafer mixture; a whisk driven by a motor and arranged for being moved or rotate in the wafer mixture to mix the wafer mixture;
  • Fig. 1 shows a front view of a cabinet having an upper raw material compartment for being dry, and a separate, lower chamber called a process compartment, in which mixing, frying and cleaning is conducted.
  • Fig. 2 is a front wiew illustrating the upper raw material compartment separately, having a powder container and a nozzle for adding water and flushing, providing dry wafer powder and water, respectively, to the process compartment.
  • Fig. 3 shows a front view of the process compartment in which powder is batch measured into the batch and mixing container, and in which the flushing nozzle adds a desired amount of water, in a preferred embodiment in a desired number of small impacts, until the desired amount of dry wafer powder mixture in the batch measurement and mixing container, hereafter called the batch container.
  • actuators for horizontal and vertical movement of the batch container with a wafer iron with corresponding actuator, and an outlet for drain water.
  • FIG. 4 shows a side view as seen from the left side of the underlying process compartment portion of the apparatus shown in Fig, 3, such as the illustration would be without a side panel.
  • a section of the rear wall of the process compartment with an outline of actuators for vertical and horizontal movement of the batch container for wafer mixture.
  • a motor and a rotating weight cell arranged on this actuator system.
  • the batch container may also be used as a moveable container for filling, weighing, mixing, pouring, washing and flushing may be conducted by means of the same container.
  • FIG. 4 is shown an upper wafer iron in an elevated posture in an oblique angle view (transparent so as to see the behind arranged batch container), and a lower wafer iron in an end view arranged on a frame at the left sidewall (facing the reader in this Figure), with parts of the drain system shown in broken lines.
  • Fig. 5 a shows parts of the image of Fig. 4, with the mobile and motorized rotating batch container arranged on the weighing cell, which further is arranged on the horizontal (inward and outward with respect to the image plane) running actuator, further being arranged on a vertically running actuator.
  • Fig. 5B shows a side elevation view of a wafer iron, here shown the lower wafer iron, with a wafer pattern only indicated.
  • Fig. 6 illustrates a front elevation view of the process compartment in which the weighed batch of wafer mixture is being mixed by means of the whish, and in which the batch container by means of the vertically running actuator is lowered from the water nozzle so as for the batch container to run free of the whisk.
  • the batch container is in this position ready for being moved towards the wafer iron which is arranged aside of the whisk and the water nozzle so as to avoid dripping on the wafer iron both in an open and a closed state.
  • the wafer iron is here opened in that the upper wafer is swung up in order for the lower wafer iron to be ready to receive the wafer mixture from the batch container. Please notice that the outlet is arranged under the whisk and the nozzle in order to receive possible drops when the batch container is elsewhere.
  • Fig. 7 shows the batch container transported to a position over the lower wafer iron and ready to be turned to pour the contents into the lower wafer iron. Highly advantageously the lower wafer iron would start being pre-heated so as for the frying of the wafer's lower side could commence immediately after the wafer mixture arrives in the wafer iron.
  • Fig. 8 shows the batch container pouring the wafer mixture into the lower wafer iron.
  • Fig. 10 shows the evacuated batch container having been run away from the wafer iron and placed below the whisk and the flushing nozzle, whereby the upper wafer iron has been turned down by means of the actuator and being closed on to the wafer mixture so as to shape the upper surface of the wafer in a desired pattern and being fried.
  • Fig. 11 shows the wafer iron being opened through the upper wafer iron elevating the wafer iron. Simultaneously the batch container has been.
  • Fig. 12 shows that the wafer may be taken out of the wafer iron independent of the mixing cup may be run to a lowered position and turned above an outlet.
  • the batch container should be run back to up below the nozzle for each flushing after the washing, particularly from hygienic considerations if no mixture shall be immediately prepared.

  • Fig. 3 shows a front elevation view of the process compartment (200) with a batch measurement- and mixing container (24). Dry wafer powder (8a) is about to be dropped down through the powder channel (216) and being batch measured to a desired amount in the batch- and mixing container (24). The way that the amount of dry wafer powder is determined, is explained below. A flushing nozzle (30) fills in a desired amount of water.

  • the upper frying plate (4b) also named “the upper wafer iron” (4b) in an elevated position in an oblique view
  • the lower frying plate (4a) also named “the lower wafer iron” (4a) in an end view and arranged on a frame on the left sidewall (facing the reader in this figure), and portions of the outlet system.
  • the batch container (24) is arranged on a weighing cell (27) for batch-measuring desired masses of dry wafer powder (8a, 8b) and fluid (12) for blending of the wafer mixture (8).

  • the nozzle head (30) comprises also a ring nozzle (32) for approximately radial flushing of the container's (24) inner wall (25). It may also be advantageous if the whisk is rotated for short periods in order to stir the liquid in the batch container without the fluid to be centrifuged over the edge of the batch container. This is particularly important if there shall only be flushing water in the batch container.
  • a frying plate (4a) or "a half part of a wafer iron” is arranged on a heat conductive paste (41) on a first metal plate (43) having an electrical resistive heat foil (5a) arranged on the rear side, resting against an insulating plate (45), preferably made of ceramic paper, further arranged on a second metal plate (47), all arranged on separation pieces on through rods on a third mounting plate (49).
  • the upper iron or frying plate (4b) has a shape corresponding to the shape of the frying plate (4a) for being combined to envelope and shape a fried wafer, and is correspondingly built up and arranged generally upside-down, and arranged rotating.
  • the upper wafer iron (4b) is moved by an arm to a moment arm on an axle on an electrical motor.
  • the purpose of arranging an aluminium plate upon the heat element is that the aluminium plate conducts heat in a sufficient degree through to the plate, while the frying plate (4a, 4b) may be exchanged without having to exchange the heating element. Likewise one may exchange the heating element without rejecting the frying plate.
  • This is advantageous for large entity use, and may divide the parts costs nearly by half when repairing the wafer irons.
  • a considerable problem with the known art is that the wafer iron is hot during long periods of time, often continuously. Then the fat from the previously fried wafer will remain in the iron while the power of the iron continues to burn the fat.
  • the release properties of the fat are degraded and becomes worse by time, and then the wafer may attach and part of it may remain stuck after a time, a feature that requires thorough cleaning and thus interrupted production.
  • the heat element requires large power, rather between 2000 and 3000 Watt in the preferred embodiment, a power that from an economical point of view should be essentially reduced in consumption. It is thus an essential moment not to let the heat elements in the wafer irons being turned on in a continuous mode.
  • the control device is connected so as to turn off the iron after about 60 seconds or some other period of time whereby it is expected that the wafer is finished frying and shall be taken out, and cools the iron in that the fan (290) extracts heated air.
  • control device connects the current to the resistive heat film (5a) so that the iron is heated during about 15 seconds while the mixture is blended, and the mixture is poured in when the iron is sufficiently hot.
  • the iron we use a power of about 1400 W per frying plate (4a, 4b), that is above and below, altogether about 2800 W for frying of one wafer in the wafer iron.
  • the control device uses separate current control of the lower and upper irons. The lower frying plate is heated firstly because it receives the mixture first, thus requiring more energy earlier.
  • the current is connected for the upper frying plate's (4b) heating film (5b) so as for the upper frying plate to be sufficiently hot when it is rotated and shut down towards the wafer mixture that has already become poured down into the lower wafer iron and has spread and started frying on one of the sides.
  • the method for frying wafers A method according to the invention for producing one or more wafers (2) by means of an apparatus with a wafer iron (4) having at least an upper and a lower frying plate (4a, 4b) with heat elements (5a, 5b), and an actuator (6) arranged for opening the wafer iron (4a, 4b) for filling of wafer mixture (8) and for closing said wafer iron for frying the wafer mixture to the finished wafer (), and thereby to open the wafer iron (4) for taking out the finished wafer (2), is characterized by the following steps: firstly, wafer mixture blend comprising dry materials comprising dry wafer mixture powder with flour (8a) and other dried wafer ingredients (8b) are fed from a powder container (10) to a batch container (10) as shown in Fig.
  • a supply of liquid (12) may take place to said batch container (24) from a liquid line (14) as shown in Fig. 3.
  • the liquid line may extend from a separate tank, but according to the preferred embodiment the liquid line leads from an ordinary water supply if the liquid is just fresh water.
  • One problem that arose during the testing of the prototype of the apparatus is that there is a contradiction between flushing of the batch container in order to conduct cleansing, and supply of water for batch-measurement of a correct mixing relationship in the batch container (24). During the flushing it is required to hav a certain pressure of the water sufficient for wafer mixture remnants to be dissolved and torn off from the wall of the batch container and the stirrer.
  • One way of solving these problems is to maintain the full water pressure of the flushing nozzle and arrange a separate computer controlled valve for flushing, in addition to arranging a separate water batch-measurement nozzle with a pressure reduction valve and a separate computer controlled valve for batch measuring.
  • a computer controlled valve to a pressure reduction circuit on the water supply line to the existing flushing - and batch measurement nozzle. But this requires more computer control channels in the control device, and computer controlled valves, incurring an expensive and complex solution.
  • a solution to these problems that proved to be much simpler, was to maintain the high pressure so as for the flushing to remain efficient.
  • the batch-measurement cycle of flushing of fluid (12) to the batch container (24) in a series of cycles comprising the following steps: short flushing of water (12) from the nozzle (30) to the batch container (24), short pause for stabilizing the weight cell (27), with subsequent reading off the weight cell (27) for weighing the batch container (24) with contents (8a, 8b, 12), until the weight cell (27) provides a weight indicating that the desired amount of water has been reached.
  • short flushing of water (12) from the nozzle (30) to the batch container (24) short pause for stabilizing the weight cell (27), with subsequent reading off the weight cell (27) for weighing the batch container (24) with contents (8a, 8b, 12), until the weight cell (27) provides a weight indicating that the desired amount of water has been reached.
  • the supply of dry powder mix does not constitute the same problem as the supply of water, maybe due to the lower density and speed of the powder being so small when it is fed out from the powder feeding screw and falls straight into the cup, so that the weight cell is not disturbed by the falling weight or the speed by which the weight increases.
  • mixing of the wafer mixture batch (8a, 8b, 12) takes place by means of a whisk (26) run by a motor (38) for stir-blending the wafer mixture batch to the prepared wafer mixture (8), such as illustrated in Fig. 4. Please notice that the wafer iron is shown in an open state in Figs.

  • the upper wafer iron (4b) is now in a preferred embodiment of the invention turned down using the actuator (6) and closed towards the wafer mixture (8) in the lower wafer iron (4a) so as for the upper side of the wafer to be formed into a desired pattern, and the wafer mixture to be fried to a finished wafer (2).
  • FIG. 11 shows a consecutive opening of the wafer iron in that the actuator lifts the upper wafer iron (4b).
  • the batch container (24) has been elevated to just below the flushing nozzle (30, 31 , 32) for having the walls of the batch container and the central portion of the whisk to be flushed with water, possibly with soap added to the water using a soap batch measurement unit. It is an advantage if the whisk rotates unevenly during the flushing in order for turning several sides to the water jet while keeping the flushed-off mixture moving in the water, and also for itself to contribute to tear off unused wafer mixture from the batch container's (24) wall and bottom.

  • no particular pick-out mechanism for the wafer is made, as it is expected that the machine shall be located at a place with attendants.
  • a pick-out mechanism may run into problems due to somewhat uneven and unpredictable slip properties in the wafer irons, so that the wafer is not guaranteed to be in a correct position to be picked out.
  • the wafer may for example stick half in one iron, and half in the other, and not rest nicely on the lower iron for being picked out. Since there is attendance at the site, and one expects the attendants to control the use of the machine, it appears feasible picking out the wafer manually.
  • An industrial advantage by a preferred embodiment of the present invention is that the apparatus may be connected directly to the water supply network so that no water tank would be required, neither any pump for creating a water pressure, as one would expect the water supply line to provide sufficient water pressure.
  • An other industrial advantage by a preferred embodiment of the present invention is the absence of a mud pit, and that the machine may be directly connected to the outlet network. Both these aspects reduce transport problems, and facilitates a more thorough cleaning without direct regard of the available amount of water.
  • the apparatus considerably lighter and smaller than if it should have been provided with a heavy water tank, rather with 20 liters of water, and a mud tank that should have the same capacity if in worst case all the mixture must be flushed.
  • wafers is used about the desired product.
