    SYSTEM AND METHOD FOR REDUCING PROOFING TIME OF DOUGH AND CONTROLLING GROWTH OF MICROORGANISMS IN THE PROOFING SYSTEM
    TECHNICAL FIELD
    The present Disclosure relates generally to a dough proofing system, and more specifically, to a system and method for reducing the time of proofing and controlling controlling growth of microorganisms in the proofing system.
    BACKGROUND
    Proofing refers to the final rise of shaped bread dough before baking. Proofing occurs during a specific rest period within the more generalized process known as fermentation. Fermentation is a step in creating yeast breads and baked goods where yeast is allowed to leaven the dough. Fermentation typically begins when a viable baker’s yeast or starter culture is added to flour and water. Enzymes in the flour and the yeast create sugars that are consumed by the yeast which in turn produce carbon dioxide and alcohol. A proofing door is a standard equipment in commercial kitchens and factories. The proofing door is a big metal cabinet with racks or a conveyor for trays of dough (e.g. used to make rolls, donuts and loaves of bread). The proofing door maintains a warm and moist environment for yeast to prosper and create perfectly risen baked goods. In traditional proofing ovens, the baking yeast is activated when hot water is mixed with the dough in a temperature range of 35 to 42 degrees Celsius.
    In one approach for proofing, Saccharomyces cerevisiae (i.e., yeast) is activated using light, however, it affects cell growth and ethanol formation of Saccharomyces cerevisiae. For example, red light at a wavelength of 630 nanometers can be used to stimulate cell growth of yeast. However, this slightly inhibits ethanol formation. Further, existing methods for activating Saccharomyces cerevisiae using light file to control growth of microorganisms in the proofing cabinet and / or dough.
    Therefore, in the light of the foregoing discussion, there is a need to overcome the aforementioned drawbacks in existing proofing ovens and methods due to their limitations in controlling the growth of microorganisms in the dough and proofing cabinet while activating the yeast.
    SUMMARY
    The present Disclosure provides a system for reducing the proofing time of dough and controlling the growth of the micro-organism in the proofing system, the system consists of a proofing cabinet consisting of at least one light source for radiating blue light at a wavelength that ranges from 400 to 480 nanometers to stimulate baking yeast in the dough for reducing the proofing time and to control the growth of microorganisms; - reflective surfaces on an interior surface of the proofing cabinet, providing the reflective surfaces on a uniform blue light inside the proofing cabinet; and - a humidifier that supplies steam for maintaining a relative humidity inside the proofing cabinet that ranges between 60 to 95 percent.
    The present Disclosure also provides a method for reducing proofing time of dough and controlling growth of microorganisms in a proofing system, the method comprising - radiating blue light at a wavelength that ranges between 400 to 480 nanometers using at least one light source; - providing uniform blue light inside the proofing cabinet using reflective surfaces; and - supplying steam for maintaining a relative humidity inside the proofing cabinet between 60 to 95 percent using a humidifier.

    DETAILED DESCRIPTION OF EMBODIMENTS
    The following is a detailed description of the present Disclosure and ways in which they can be implemented. While some of the fashion of carrying the present Disclosure has been revealed, those skilled in the art would recognize that other embodiments of carrying the present Disclosure are also possible.
    The present Disclosure provides a system for reducing the proofing time of dough and controlling the growth of microorganisms in a proofing system, the system consists of a proofing cabinet consisting of at least one light source for radiating blue light at a wavelength that ranges from 400 to 480 nanometers to stimulating baking yeast in the dough for reducing the proofing time and controlling the growth of microorganisms; - reflective surfaces on an interior surface of the proofing cabinet, providing the reflective surfaces on a uniform blue light inside the proofing cabinet; and - a humidifier that supplies steam for maintaining a relative humidity inside the proofing cabinet that ranges between 60 to 95 percent.
    The present system thus impairs the proofing time of the dough using blue light by increasing the activity of the yeast and simultaneously slowing down the growth of microorganisms in the proofing system. The proofing cabinet can be adapted for home use or industrial use. The proofing cabinet may be a closed cabinet. The proofing cabinet may comprise darkened plexiglass windows to restrict extrinsic radiation. The proofing system in the present Disclosure consists of the proofing cabinet but also various other parts that may be used, such as plates or conveyor belts. In the present description, when the term proofing cabinet is used, it is to be understood as encompassing all possible parts in the connection to the cabinet.
    One light source is a light emitting diode (LED). In another embodiment, the maximum distance at which at least one light source is arranged to be located from an application area (eg area where the dough is placed) is determined based on the intensity of the blue light that is emitted by the least one light source. The maximum distance at which at least one light source is arranged to be located may be modified in order to maintain the desired light intensity inside the proofing cabinet. In one embodiment, the system may comprise a lamp assembly that comprises at least one light source. In one particular embodiment, at least one light source can be located at a minimum distance of 6 centimeters from the dough when the system is in use.
    In an embodiment, a range of wavelengths of blue light is optimally selected to stimulate the baking yeast in the dough for reducing the proofing time and controlling the growth of the microorganism. The humidifier may be controlled based on the size of the proofing cabinet, the desired relative humidity to be maintained inside the proofing cabinet and the amount of steam that is supplied into the proofing cabinet over a period of time.
    According to another embodiment, the system further comprises at least one of - at least one light sensor for detecting an intensity of light from a surface of a dough or a surface of a proofing cabinet; - a humidity sensor for measuring the level of humidity inside the proofing cabinet; - a temperature sensor for measuring the temperature inside the proofing cabinet; and - an exhaust fan for maintaining the temperature inside the proofing cabinet under 46 degrees Celsius.
    The system may thus comprise only one of the above, or any combination of the above listed components. For example, the system may consist of a light sensor and a humidity sensor or a light sensor and a temperature sensor and an exhaust fan. Likewise, the system may comprise a humidity sensor and a temperature sensor, a humidity sensor and an exhaust fan or a temperature sensor and an exhaust fan. In addition, the system may comprise a light sensor, a humidity sensor, and a temperature sensor, or a light sensor, and a temperature sensor, an exhaust fan, and a temperature sensor. In the most preferred embodiment, the system comprises all of the above, i.e. a light sensor, a temperature sensor, a humidity sensor and an exhaust fan.
    The system may also comprise more than one of the components above, for example two, three, four or more humidity sensors and / or two, three, four or more temperature sensors and / or two, three, four or more exhaust fans.
    At least one light sensor may be arranged at the top portion inside the proofing cabinet, the top portion being defined when the proofing cabinet is in use. The at least one light sensor may also be placed at the bottom of the proofing cabinet or at the level of the plate that accommodates the dough. The least one light sensor can be arranged at any appropriate location inside the proofing cabinet to measure the light intensity from the surface of the dough. When more than one light sensor is used, they may be located at a similar level with respect to the height of the proofing cabinet or at different levels. For example, there may be one sensor in the top part, one in the bottom part and one in the middle part of the proofing cabinet. The at least one light sensor may be arranged at a height of the dough (i.e., the height at which the dough is placed for proofing) for measuring the light intensity (i.e., light sensor data) inside the proofing cabinet. The at least one light sensor may continuously detect the light intensity inside the proofing cabinet from the surface of the dough and the surface (e.g., disinfecting surface) of the proofing cabinet. The light sensor data may be measured to reflect the light intensity from the surface of the dough or the surface (i.e., the disinfectant surface) of the proofing cabinet.
    In one embodiment, the humidity sensor is placed near the surface of the dough to measure the level of humidity inside the proofing cabinet. The exhaust fan may maintain the temperature inside the proofing cabinet under a certain pre-set limit which depends on the use of the proofing cabinet. For example, the pre-set limit may be 46 degrees Celsius. The exhaust fan limits the temperature by exhausting excessive hot air from the proofing cabinet. The exhaust fan may exhaust the hot air from the proofing cabinet when the temperature inside the proofing cabinet exceeds 46 degrees Celsius, as measured by the temperature sensor. This may be arranged to be performed automatically or manually by a user.
    The system may further comprise a carbon dioxide sensor for measuring the level of carbon dioxide inside the proofing cabinet. The system may further measure the relative speed of a proofing cycle.
    According to another embodiment, the system further comprises a microcontroller that is communicatively connected to at least one light source, the humidifier, the least light sensor, the humidity sensor, the temperature sensor and the exhaust fan, once the Microcontroller is configured to perform at least one of - controlling the intensity of the blue light based on the light sensor data measured from the surface of the dough, maintaining the intensity of the blue light at between 0.5 to 50 milliwatts per square centimeter inside the proofing cabinet during a proofing cycle; controlling the humidifier based on the size of the proofing cabinet, the desired relative humidity to be maintained inside the proofing cabinet and the amount of steam that is supplied to the proofing cabinet over a period of time; and - activating the exhaust fan when the temperature inside the proofing cabinet exceeds 46 degrees Celsius.
    When a Microcontroller is used, it is preferably communicatively connected to all the different components of the system, in order to automatically control the use of the proofing cabinet or the entire proofing system.
    According to this embodiment, the intensity of the blue light is maintained between 0.5 to 50 milliwatts per square centimeter. The intensity of the blue light may be maintained at 0.5, 1, 5, 7, 10, 15, 20, 25, 30, 35, 40 or 45 milliwatts per square centimeter up to 1, 5, 7, 10, 15, 20 , 25, 30, 35, 40, 45 or 50 milliwatts per square centimeter. According to yet another, an intensity of the blue light is maintained, inside a proofing cabinet, at a level of about 30 milliwatts per square centimeter for activating the baking yeast. The intensity of the blue light inside the proofing cabinet may be controlled over a period of time, preferably by the Microcontroller.
    According to another embodiment, the wavelength of the blue light is between 405 to 480 nanometers. The wavelength of the blue light can be from 400, 405, 410, 415, 420, 425, 430, 435, 440, 445, 450, 455, 460, 465, 470 or 475 nanometers up to 405, 410, 415, 420 , 425, 430, 435, 440, 445, 450, 455, 460, 465, 470, 475 or 480 nanometers.
    According to yet another embodiment, the system further comprises at least one support for the dough made of a material that is transparent to the blue light. In one embodiment, at least one support is a plate, a tray or a conveyor belt on which the dough is placed. The plate or tray may be made of glass or another material that is transparent to the blue light.
    According to another embodiment, the reflective surfaces are made of high diffuse reflectance aluminum composite. The reflective surfaces can also be made of any other suitable material, i.e. a material that has high enough reflectance and that is suitable for the food industry, such as stainless steel.
    According to yet another embodiment, the system further comprises a conveyor belt unit that guides the dough inside the proofing cabinet, comprising at least one sensor for collecting information about production speed and volume analytics during the proofing cycle. The information about production speed may comprise the speed of the system at which the dough is proofed. The information about volume analytics may consist of a quantity of dough that is proofed over a period of time inside the proofing cabinet. The conveyor belt unit may run intermittently during the proofing cycle. The conveyor belt unit may comprise an automatically controlled conveyor belt with photoelectric sensors. In one embodiment, the conveyor belt unit is run through a proofing cabinet like an industrial static intermediate proofer or a spiral proofer.
    The light source of the present system is used to stimulate baking yeast in a dough and to control the growth of microorganisms. These microorganisms can present either in the dough or in the proofing cabinet, coming for example from outside the air. The light source can thus be used, in addition to the proofing cycle, also during the disinfection cycle, while there may or may not be any present in the proofing cabinet. Preferably, there's no dough in the proofing cabinet while the disinfection cycle is running. The system may be automated in such a manner that it can sense when it is empty, i.e. without any dough, and can then run the disinfection cycle during this time. Thus, in one embodiment, the disinfection cycle is initiated or selected after removing the dough from the proofing cabinet. The Microcontroller can increase the intensity of the blue light to disinfect the proofing cabinet.
    Thus, according to yet another, during a disinfection cycle, the Microcontroller is configured to adjust the intensity of the blue light to the disinfect the proofing cabinet based on the light sensor data measured from the disinfected surface of the proofing cabinet, the intensity of the blue light inside the proofing cabinet is maintained at between 10 to 120 milliwatts per square centimeter during the disinfection cycle. According to another embodiment, the intensity of the blue light inside the proofing cabinet is maintained at between 50 and 120 milliwatts per square centimeter during the disinfection cycle. Typically, the intensity of light during the disinfection is higher than during production, i.e.. during proofing of dough. The intensity of the blue light during the disinfection cycle may be maintained from 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110 or 115 milliwatts per square centimeter up to 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105 , 110, 115 or 120 milliwatts per square centimeter.
    According to yet another embodiment, the system further comprises an indicator of at least one of the progression of the disinfection cycle, the progress of the disinfection cycle, the remaining time to finish the proofing cycle, and the remaining time to finish the disinfection cycle. In one embodiment, the indicator is an electronic display.
    According to another embodiment, the system further comprises a server communicatively connected to the Microcontroller for providing a timing plan for adjusting the intensity of the blue light to disinfect the proofing cabinet (or the proofing system), so the server is optionally configured to monitor disinfection cycles and to store information related to disinfection cycles in a server database. The server may be communicatively connected to the Microcontroller through a network. The server may consist of a server database that is configured to store the timing plan. The timing plan may be pre-configured using the server. The timing plan is a function of a schedule based on which intensity of the blue light is adjusted to disinfect the proofing cabinet. The timing plan may consist of a time period in a day at which the intensity of the blue light is adjusted to disinfect the proofing cabinet. The information related to the disinfection cycles may consist of the time taken by the system to disinfect the proofing cabinet, the intensity of the blue light that is radiated inside the proofing cabinet etc.
    The present Disclosure also provides a method for reducing proofing time of dough and controlling growth of microorganisms in a proofing system, the method comprising - radiating blue light at a wavelength that ranges between 400 to 480 nanometers using at least one light source; - providing uniform blue light inside the proofing cabinet using reflective surfaces; and - supplying steam for maintaining a relative humidity inside the proofing cabinet between 60 to 95 percent using a humidifier.
    According to an embodiment, the method further comprises at least one of - detecting an intensity of light from a surface of a dough or a surface of a proofing cabinet using at least one light sensor; - measuring a level of humidity inside the proofing cabinet using a humidity sensor; - measuring a temperature inside the proofing cabinet using a temperature sensor; and - maintaining the temperature inside the proofing cabinet at 46 degrees Celsius, using an exhaust fan.
    According to another embodiment, the method further comprises at least one of - controlling an intensity of the blue light based on the light sensor data measured from the surface of the dough using a microcontroller, maintaining the intensity of the blue light is maintained between 0.5 to 50 milliwatts per square centimeter inside the proofing cabinet during a proofing cycle; controlling the humidifier based on the size of the proofing cabinet, the desired relative humidity to be maintained inside the proofing cabinet and the amount of steam that is supplied to the proofing cabinet over a period of time using the Microcontroller; - activating the exhaust fan when the temperature inside the proofing cabinet exceeds 46 degrees Celsius using the Microcontroller; - adjusting the intensity of the blue light to disinfect the proofing cabinet based on the light sensor data measured from the disinfected surface of the proofing cabinet during the disinfection cycle, using the microcontroller, then the intensity of the blue light inside the proofing cabinet is maintained at between 10 to 120 milliwatts per square centimeter during the disinfection cycle; - providing a timing plan for adjusting the intensity of the blue light to disinfect the interior surface of the proofing cabinet using a server; and - monitoring disinfection cycles and storing information related to disinfection cycles in a server database.

Thus, for example, any combination of steps listed above is possible and be considered as disclosed in this description.
    In an example, the proofing process is revealed. Initially, dough may be guided into a proofing cabinet through a conveyor belt unit or may be manually placed inside the proofing cabinet. The proofing cycle may be selected from the menu provided in a screen attached to the proofing cabinet. The relative humidity inside the proofing cabinet may be adjusted using a humidifier based on parameters (e.g., temperature, humidity level and carbon dioxide level inside the proofing cabinet and relative speed of the proofing cycle) of the selected proofing cycle. The relative humidity inside the proofing cabinet may be maintained using a system based on humidity sensor data. The humidity sensor data can be measured using a humidity sensor. The exhaust fan can be activated in order to maintain the temperature inside the proofing cabinet when the temperature inside the proofing cabinet exceeds the threshold limit (e.g. above 46 degree Celsius). Preferably, an intensity of blue light inside the proofing cabinet is controlled and measured throughout the proofing cycle. The intensity of the blue light inside the proofing cabinet can be measured using at least one light sensor. The proofing cycle may be completed according to the desired parameters of the selected proofing cycle. In one embodiment, the proofing cycle is completed when the threshold value of the desired parameters is attained.
    In another example, the disinfection process is revealed. Initially, dough and visible dirt are removed from a proofing cabinet. In an over, in conveyor type proofing cabinets, sensors that control a conveyor belt can be programmed to allow the conveyor belt to run only if the proofing cabinet is empty. The conveyor belt is activated and run throughout a disinfection cycle. The disinfection cycle may be selected from a menu provided in a screen attached to the proofing cabinet. An intensity of blue light inside the proofing cabinet can be controlled and measured throughout the disinfection cycle. The disinfection cycle may be ended when the desired light intensity at the application area of the proofing cabinet is attained. In one embodiment, the application area is an area or a cavity inside the proofing cabinet at which the dough is placed for proofing.
