Description

MOLD FOR FORMING AT LEAST ONE FOOD PRODUCT FIELD OF THE INVENTION The invention relates to a mold with at least one depression for forming food products that is at the same time configured for optimizing the design of the mold, the tion line and/or the tion process. Said mold has a filling side that is open to be filled with at least one food mass and/or at least one food product ient and a back side opposite to said filling side.

BACKGROUND OF THE INVENTION Molds are efficient tools in order to give food products a specific form. Due to their essential role during the production process, to. they pass through a significant number of production stages, they are exposed to various mechanical, ambient (such as thermal) and chemical influences. For example, if the food products are removed by knocking the mold, the mold may have to Withstand significant accelerations, When the mold is cleaned after production in a washing cycle, the mold is within an environment strongly ced by chemicals that assist in cleaning the mold for the next production cycle. Here, the als may have the potential to deteriorate the mold's material and therefore cause damage to the mold in the long run. In addition to ical and chemical loads, the ambient ions surrounding the mold change icantly as well. After filling the mold, the mold may well be cooled down to temperatures below 0°C in order to achieve a fast solidification of the food product. After the removal of the food product, the mold may be directly transferred to the washing process that normally requires temperatures of about 50°C to 75°C. in other words, molds can be exposed to a substantial change in temperature during a short period of time.

Although many ters may be used to optimize the production process, the extent to which they influence the state and integrity of the mold is not generally known. The ic requirements that have to be fulfilled according to the rules set out for the food industry narrows down the choice of materials during the design phase of such a mold to the materials certified for such a use. In other words, the best material and design to withstand the conditions the mold is exposed to during the production process may not be legitimate for use with food products.

WO 97043 PCT/U$2012/020903 Due to the repetitive use of molds during the production process, at some point problems such as e may have negative effects on the production process. For example, a condition failure is chipped-off pieces of the mold’s al. This bears the risk that parts of the chipped—off material ends up within a food product.

Therefore, in such cases, the production s is brought to an immediate halt. As a consequence, the food products that have been formed during the chipping-off have to be discarded, and the production line has to be checked for any residual pieces of material left within the machinery. Since it is hard to determine when the mold got damaged, a large number of food products may contain pieces of broken off material and the entire production run may have to be discarded to avert any risks to the health of the consumers. Only after such procedure, the production continue. These. safety measures result in a delay of the production and therefore in undesirable onal costs.

In order to avoid such costs, the molds are. designed with high safety s, leading to molds that are bigger in size and therefore heavier and harder to move. in addition, the lack of detailed knowledge concerning loads and the environmental influences acting on such a mold results in a rather empirical design principle.

Hence, there is a need for optimization of the design of the mold and/or the production line and/ or the production process to avoid the ence of failures of the mold during production such as chipped—off material due to fatigue and/or high loads.

Therefore, a first way to avoid structural problems with the molds is by zing their design. As laid out above, this option can not be fully exploited up to now due to the lack of knowledge about the loads acting on such a mold during production since sensors utilized for food production only register the state of the food product in the mold such as the ature or the viscosity.

A second way is to develop means to detect a failure of the mold’s material. For example, the German patent application DB 10 2004 012 580 Al uses a camera and image ition to ine if all food products were removed from a mold.

Although this technology may be applied to monitor the integrity of the molds, such a technique is in general stationary and therefore limited to only one stage of the produco‘on.

Thus, DE 10 2604 012 580 could for example be used for the process and assembly for producing a confectionery product disclosed in EP 1 676 485 Al, which forms the basis for the two-part form of ndent claim 1. EP 1 676 485 A1 describes injection-molding device for molding a tionery product which is shaped on all sides. It can be produced by (i) preparing an aerated sugar mass, (ii) injecting said mass in a mould cavity defined by two separable mold surfaces having a temperature below 0°C, and (iii) separating the mold surfaces and ng the product.

Y OF THE INVENTION The objective of the invention was therefore to provide the means that allows optimizing the design of a mold for food. ts, the corresponding production line and/or the corresponding production process.

The present invention solves the above mentioned issues by providing a mold, an apparatus, a method and a use in order to collect and transfer data describing the state of the mold. This solution is brought forward by the. subject matter of the independent claims, wherein the dependent claims describe further aspects of the invention, in a first aspect of the invention, a mold for forming at least one food t is equipped with a measurement unit. The mold has a g side and a back side opposite to said filling side. Further, the measurement unit comprises measuring 3 means configured to measure at least one parameter of the mold while the mold is used in the production line or testing facility. Further, the unit comprises a data transferring device configured to transfer data to an external processing unit.

Preferred food products are confectionery products (including ate, candy, g gum and ice«cream), bakery products {including bread, cakes, pastries and. dough) and/or dairy products (including cheese).

The measurement unit of the mold tates data acquisition directly at the point of interest, namely the mold itself. Further, the mold may acquire and/or transfer the data on~line and in real time. In one ment, the measurement unit may only comprise measarring mean-3, i.e. one or more sensors, and a data transferring device Therefore, the design of the measurement unit can be kept simple and compact. This has the age that such a measurement unit only requires a small installation space for passing through the different production steps together with the mold‘ This architecture of the measurement unit also allows for a robust design that is more fit to endure the production environment and, therefore, offers a longer life \VO 20121097043 PCT/U82012/020903 time and higher reliability, The data transfer interface makes it possible to outsource at least parts of the data processing and ore further reduces the size of the device. The ing measurement unit is small and has only few parts that are exposed to the measurement environment and that have to be protected to avoid malfmictlons. However, if a malfunction occrrrs, it is also easy to exchange such a device. due to its size and at a low cost.

In another embodiment of the invention, the measuring means comprise at least sensor that measures mechanical parameters such as stress, strain, acceleration, orientation, ty and/or force, The sensor or sensors may apply tive and/ or resistance working principles. For example, strain and stress may be measured using at least one strain gauge, which in another embodiment are ly ed to the mold and protected by a protective layer, if ary. Other examples are gyro s measuring the orientation of the mold, acceleration sensors and/ or force sensors, measuring the acceleration or force of the mold, respectively, in at least one translational and/or rotational axis. Although in all these examples, the sensors are preferably in direct contact with the mold, it is also possible to use sensors that apply a non—contact measurement principle such as ultrasound or laser. The latter enables, for e, the measurement of the velocity and/or on of the mold, Which parameters or which combination of parameters is measured, depends on the objective of the measurement. In one embodiment of the invention, the measuring means is configured to measure at least one parameter of the structure or structural integrity of the mold. Additionally and or in another embodiment, it might be of interest to measure accelerations that occur in the demolding station, for example a mold knockout n, where the at least one food product is d. from the mold. In the ng n this measurement may be complemented with a measurement of the orientation of the mold. A person skilled. in the art will appreciate that it may also be advantageous to choose a combination of sensors that make it possible to identify certain events such as twisting or rotating the mold during production in order to draw conclusions concerning the cause and effect of certain production stages on the mold. It might also be desirable to investigate the interrelationship between multiple parameters. For example, measuring the temperature that the mold is exposed to during production may be useful to explain parts of the stresses and strains occurring within the mold’s material.

PCTIU82012/020903 According to another embodiment of the invention, the measuring means comprise at least one sensor, or in some embodiments multiple sensors, to measure ambient parameters such as pressure, temperature, humidity and/ or light. As explained above, changes in temperature may cause l stress within the mold. Humidity on the other hand might affect the heat er that occurs to the mold, for example when washing said mold, and therefore indirectly determines the temperature affecting the mold. Light (such as infrared light or UV light} could be used during production and may well have adverse effects on the mold’s material and therefore on the ural integrity of the mold. in another embodiment of the ion, the measuring means comprise at least and in some embodiments multiple sensors to measure one or more chemical parameters such as partial pressures of gases, sugar t, viscosity, fat content, protein and/or pH-value. Although at first sight, these parameters seem to reflect only the quality of the foocl product itself, they may also have an effect on the longevity of the mold. Certain gases may affect the mold’s material and therefore their quantification might be useful to estimate the environmental nces the mold is exposed to. Another example is the pl‘l—value, since it represents a l parameter that might have adverse effects on the mold’s materials. i in one embodiment of the invention, the measurement means are configured to withstand or measure acceleration within a range of O to 30 G and/ or temperatures within a range of 60°C to 120°C. High acceleration occurs, for example, when the food products are knocked out of the mold in a mold knockout station, acting as demolding n. However, such rations may also occur when the mold is transferred from one production station to the next caused by the ort means.

Therefore, the ability to withstanci such influences without a negative effect on the measurement is crucial. During the production of food products, the different production stages may require a wide range of temperatures that the measurement unit is exposed to during measurement. This range comprises low temperatures such as below 0°C to cool down the food product after filling the at least one food mass into the mold, or rather high temperatures, for example occurring during g or washing and dismiecting the mold. in addition, the measurement unit may be protected from the measurement environment by at least one protective layer such as a sealing layer. Here, it is especially ant that the protective layer does not affect the ement in an undetermined way. This ment of the invention especially takes the effects of the measuring environment on the measurement unit into account. The protective layer around the measurement unit is especially useful when the mold is washed since it may be hard to find a location where the measurement unit is ly protected from the measurement environment so no ction of the unit occurs.

It may be advantageous to design the protecn‘ve layer in a way that it also forms a housing for the measurement unit in order to simplify die attachment of the measurement unit to the mold.

In another embodiment of the invention, the measurement unit is ed to or removably attached to said mold, preferably to the back side of the mold. Further, the measurement unit may have a modular design in order to t different measuring means. Such a modular design enables a wide range of different s to measure the at least one parameter that can be custom fit to each particular question. concerning the loading of the mold. Further, the r design allows for an optimum placement of the sensors on the mold. if the optimum placement for multiple potentially different sensors is at several locations on the mold, the measurement unit may well be separated into a main unit comprising the data transfer interface and optionally at least one measuring means and at least one ary unit comprising at least one measuring means connected to the main unit.

This is especially the case if multiple strain gauges are applied to the mold in order to determine occurring strain at different locations of the mold in order to estimate the loads acting on said mold during production or testing. Another exemplary application may be the attachment of several acceleration sensors in order to optimize the effectiveness of the mold knockout station at ent locations of the mold in order to quickly and reliably remove the food product from the mold.

In a further embodiment of the invention, the processing unit is connected to a control system for controlling the production line or the g facility. Integrating the measurement unit in such a way allows optimizing the production s for the food product beside the aforementioned improvement of the design of the mold and the tion line. For example, the cooling of the molds when containing a food product can be closely ised in order to better understand how fast heat is transported away from said product during solidification of the food mass. Another example may be the objective to e a threshold ature of the mold during the washing process in order to guarantee that the mold fulfills all hygienic requirements before entering production.

PCT/U52012/020903 Up to now, it y takes too long before a defect in a mold is discovered, which in turn causes high additional costs that could be reduced by decreasing the response time to such an event. Therefore, it may also be of interest to monitor those parts of the mold that are susceptible to be damaged in order to enable a fast response if, for example, material of the mold chips off. This solves the issue of having to discard a complete production run of food products in order to assure that no chipped-off parts of the mold remain within these products, representing a potential danger for the consumer.

In another ment of the invention, the data transfer interface comprises a wireless and/or a plug connection for transferring the measurement data. The transfer of the data may take place during and/or after the collection of the data from the measuring means. If seen as necessary, a data logging unit may be added to the ement unit as an integrated or modular entity. Which architecture is chosen for the ement unit depends on the task the measurement unit has to fulfill. For example, if the measurement unit is intended for optimizing the design of the mold, a plug connection for transferring the data after the measurement has taken place may well be sufficient and results in an advantageously simple design of the unit. 011 the other hand, if the measurements are used to control or monitor the production process or the mold at least during a set time , a constant transfer of data during production may well be the better operation mode for the measurement unit In another embodiment, probably in combination with the aforesaid, it might be of advantage to also design the data er interface as a module in order to ensure an easy and reliable transfer of measurement data.

In another ment of the invention, the measurement unit further comprises a data logging unit to record the measurement data received from the measming mans. Such a data logging unit has the advantage that data measured while passing through production or testing can be read out after at least parts of the production or testing have been ed. In order to do so, the data logging unit may be easily connected. to a processing device such as a computer for the subsequent data analysis by cable or ss connection. This provides a cost effective way to collect data of the loads affecting the mold during production or testing.

In r embodiment of the invention, a food production line comprises a mold as described above that is passed through at least one of the ing production line stations or testing facility stations such as a mold filling station, a mold washing PCT/U82012/020903 station, a mold twister station, a mold rotator station, a mold cooling tunnel, and/ a ing station. All these stations are production ns that fulfill tasks commonly found. for the production of food products. Adapting the architecture of the measurement unit to provide optimum functionality for at least one of these stations ensures that only data that can, subsequeniiy be used for optimizing the design of the mold and production line and/or the production of food products is acquired. The insight that this data delivers, ensures that the design of the molds and the production. lines becomes less empirical since it is based on analytical s of common engineering techniques such as finite element modeling According to the aforementioned, the mold is intended for use in a food production line and/or testing facility, This is especially ant, e molds for producing food products have speciai requirements such as they have to be biocompatibie and have to fulfill hygienic requirements, Le. it has to be le to disinfect them.

In a further embodiment of the invention, the mold further comprises identification means to distinguish the at least one mold equipped with a measurement unit from other molds used in the production. Hence, one or more molds that are equipped i with measurement units may be passed through the tion line. For the i optimization of the mold design it may well be ient to pass the mold h the at least one production step without filling the mold. if the measurement mold is used among at least one other tion moid that is fully integrated in the production s, Le. it used for the production of the food product, it is desirable to equip at least the measurement mold with identifying means. These identifying means, such as transponders or markings, facilitate the manual and/ or automatic distinction between a normal tion mold and the measurement mold. This makes it possible to ively skip production steps such as the filling of the mold.

For producing a food product while using a mold as described above, a related method has been developed. In a first aspect of this method for producing at least one food product comprising a mold, the method includes several steps. One step is starting the measurement of the at least one parameter with the measurement unit.

Once at least parts of the at least one parameter has been obtained, another step is to stop the measurement. Further, the at least one parameter is measured while the mold is passed through at least one production line station or testing facility station in which at least one production step is performed.

According to another embodiment of the invention, the method of producing the at least one food product comprises at least one production step at least once. Such a step is filling the mold in a mold filling station with at least one food mass and/or at least one food product ingredient such as particulate material. Another step is washing the mold in a mold g station before and/ or after the mold is filled in at least one filling station in order to remove remaining food products or remainders of food products from the mold. Further, twisting the mold in a mold twister station at least once, preferably to remove the at least one food product or to reorient said mold for another tion step may also be performed. r step in the production of the at least one food product is cooling the mold in a mold cooling tunnel, preferably with at least parts of the food product within the mold, in order to speed up the solidification process of the food mass and/or the food product ingredient after the mold has been filled. A technique for removal of a food product is passing the mold through a demolding station to separate the food product from the mold. An example for such a demolding station is a mold ut station in which the mold is d in order to remove the at least one food product. In other words, the food product is d by accelerating the mold in at least one direction. Another technique to remove the food product is to loosen the at least one food product by vibrating the mold. r, a combination of these techniques may l also be applied. l Further, passing the mold through more than one production station may be especially useful if the objective of the ement is to record the loading cycle for parts of or a te production cycle.

It is also within the scope of the invention to start and stop the measurement of the at least one parameter at least once during, before and/ or after the production s. This is advantageous if data is to be recorded only at set time als, for example, if only n stages in the production are to be monitored or investigated.

This avoids sorting out the data after each measurement in order to reduce the recorded data points to the ones of interest in case data has been recorded during the whole production cycle.

Another embodiment of said method is to transfer the measurement data from the measurement unit to an external processing unit with a data transfer interface in order to control the production process and/or to improve the design of at least parts of the production line or {he testing faciliiy. Although the data acquired in this me: is best fit for improving the design of the mold, it might also be useful to improve the design of other parts of the production line. For example, it is possible to improve the production by optimizing the precision or the path of the molds through the production steps. It also becomes possible to investigate the time intervals of certain steps during production such as the g of the mold or cooling of the mold to save production time.

In a further embodiment of the method, the measurement data is transferred aneous to and/or after the at least one produclion step. lncluding such a task in the production method is especially useful when data acquired with said mold to be used for directly controlling or monitoring the production process and/ or the mold. This is the case if the mold has to reach a certain temperature during the cooling process before it can be transferred to the next production step. Another example is the heating of the mold during a washing cycle in order to fully remove remaining chocolate. mass and/or food product ingredienls in said mold after l of the at least one food product.

BRIEF DESCRIPTION OF FIGURES Figure 1 shows a mold comprising a measurement unit.

Figure 2 shows the measurement unit in more detail.

Figure 3 shows a graph with measurement results ed with the mold.

DETAlLED DESCRIPTION OF PREFERRED EMBODIMENTS Figure I shows a mold 10 for food products with a measurement unit ‘20 ed to it. The mold 10 has multiple depressions 14 with a specific shape for forming chocolate bars. The chocolate bars may well contain another food product ingredient such as a parficulate material, for example, nuts and/or s.

Although the mold '10 is for the production of ate bars, the invention may also be d to molds for other food ts such as prah’nes or eam. The mold is structurally reinforced with reinforcing means, preferably at: least one rib ‘12, its back side 11.

The measurement unit 20 is attached to the back side 11 of a rectangular mold 10, located approximately one. third of the mold’s side length away from the boundary, respectively. The measurement unit 20 is preferably r in one of its dimensions than the height of the. ribs 12 so that the mold 10 could be put on its back side 11 on plain surface without the measurement unit '20 touching said surface.

PCT/U52012/020903 Measurement unit 20 may be attached to at least one mold 10 during normal production in order to tate the optimization of the design of said mold 10, the design of at least part of a production line and/ or the optimization of the tion process. The measurement unit 20 is preferably attachable and detachable from said mold '10, r, it is also within the scope of the invention to integrate the measurement unit 20 into the mold 10, for example to be part of the reinforcing means or the depressions 3.4. Although measuring means, a data transfer interface 26 and a data logging unit are ated within the measurement unit 20, it has very compact built (Figure '1).

Figure 2 shows a more detailed View of the measurement unit 20 that comprises an integrated circuit board 24, a data transfer interface 26 attached to said t board 24, a protective layer 23 configured to protect the measurement unit 20 from the measurement environment, a switch 21 to activate or deactivate the acquisition of the at least one parameter and an energy supply 25 such as a battery. The measurement unit 20 further has a local coordinate system 22 linked to an acceleration sensor thereon. The measurement unit 20 may also n at least one additional sensor, for example a temperature sensor and/or a sensor to detect humidity. In this exemplary architecture of the measurement unit 20, the data transfer is performed by the data transfer interface 26 by a cable tion after at least parts of the measurement has taken place. However, it is just as easy to add a wireless data transfer to the data transfer interface 26 or to replace it altogether.

In order to start the measurement, the measurement unit 20 is activated. This may be ed by using a simple switch 21 or by remote control. in order to exchange ds between a remote control and the. measurement unit 20, the wireless data transfer interface may be used or an integrated additional remote control unit. The remote control allows to turn the data acquisition of the measurement unit 20 on and off at least once, for example, to only acquire data of ic production steps.

Another possibility is to program the measurement unit 20 at which time intervals and/or sampling rates the measurement unit 20 should record and/or transfer data from the measuring means.

The. measurement may be d before the mold ll) enters the production process as well as at a point of time after the mold ‘10 entered the production process or at multiple times during the production. Once the measurement is started, the measurement unit 20 records the at least one mechanical, chemical and/or ambient PCTI'U32012/020903 parameter. The resulting data points are either logged by a data unit and/or may be transferred in real—time while the data is ed. It is also an option of the present invention to specifically collect data for specific ters by only activating the corresponding measuring means. In other words, only the measuring means required in order to fulfill the measurement task, such as investigating the loads acting on the mold 10 in at least one tion station, are activated when starting the measurement.

During measurement, the protective layer 23 seals off parts of the measurement unit that are susceptible to the measurement environment. The measuring means may be completely integrated into said measurement unit 20 and/ or may also have a modular architecture. A modular architecture is for example advantageous if it is desirable to place the measuring means at different locations of the mold 10 to ensure an optimal data ition. In case of a modular architecture of the ement unit 20, the measuring means might either be connected by cable connection and/ or wireless connection. The latter has the advantage of an easier installation. The location for the measuring means has to be chosen according to the task on hand. For example, in order to m a measurement of the acceleralion the mold '10 is exposed to, the measuring means should not be placed at an instantaneous center of rotation of the mold 10. If such a placement cannot be avoided, more than one ration sensor may be used or more than one measurement cycle can be performed. As a person. skilled in the art will appreciate, multiple sensors have to be used as well for recording stress fields, strain fields, temperature fields, humidity fields and/ or force fields. b1 order to ly acquire data about the strains and stresses within the mold 105 during tion, additional strain gauges may be connected to the measurement unit 20 (not shown).

Figure 3 shows post~processed measurement results of a ement unit 20 after the mold 10 has passed through several production stations, namely a twisting station, a mold r station as well as a demolding station, respectively, mold knockout station, and. has been transported between these stations by transporting means. As can be appreciated in figure 3, during the time of ement, the acceleration over lime in all three translational axes (51, 52, 53) as well as humidity and ature 40 have been recorded. The temperature is imately constant throughout the whole measurement, wherein the humidity 30 decreases over time with a slight increase at the and. The measurement of the acceleration shows peaks that either corresponds to the twister station, the mold rotator or the demolding station. Further there is unsteady movement of the mold to between these production stations while the mold 10 is transported by the transporting means. in order to exactly determine. the reasons for the dy movement of the mold 10, the measurement cycle may be repeated several times and /or measuring means may be added that record the exact position of said mold 10 that can later on be related to the occurrence of unsteady movement.

After stopping the measurement, again by using a normal switch 21 and/ or a remote control, the. data can be post-processed for subsequent use, for example by applying common engineering techniques such as finite element analysis or boundary analysis. Further, other analysis techniques such as frequency analysis may be used, for e, to detect if material has been chipped off the mold 10 and therefore changed the frequency profile of said mold ‘10.

The measurement data may also be used to control the production process on~line and in real-time at least by ring the state of the mold '10 during production during set time intervals that are, for example, found to be critical for the integrity of the mold 10. in y, the new and inventive way to measure the state of the mold 10 during 3 the production of food products provides the means to reliably and quickly provide l data by measuring at least one parameter delivering objective valuable ation. 3 This information may he used for the design of new molds or the retrofit of existing E molds. For the latter case, said ement unit 20 can be attached to a mold ll] that shows, although carefully designed unexpected behavior such as unwanted vibrations during production. The analysis of the acquired data makes it possible to point out the weak spots of such a mold 10 and ore solves occurring problems with existing molds without having to design complete new ones.

Recording chemical ters such as the pH~value may also help to optimize the mold 10, the production line and/ or the production s. This is for example the case for a mold washing station in order to determine how much the g liquid changes the pvaalue the mold 10 is exposed to. For such a purpose, the measuring means may well be attached to the front of the mold 10 or be integrated within the mold 10 so that they are in contact with the front side of the. mold 10, for example by being part of the surface of the depression 14 within the mold 10.
