BACKGROUND
[0002] The grain processing industry is a vital component of the global food industry, responsible for processing and refining various types of grains such as wheat, rice, corn, barley, oats, and the like. Dehydration or drying is the most tech intensive and sensitive operation in grain processing industries. This is where the food grains are uniformly dried in grain dryer with intermittent tempering. The main objective of a grain dryer is to uniformly dry the grain to a desired moisture level without any damage or alteration to the grain quality, so that it may store, process, or milled further.
[0003] Currently, the most used method for drying grains in the grain processing industry is the use of Double Inlet Double Width (DIDW) centrifugal blowers. These blowers circulate hot air through a drying chamber, where the grains are dried. They are designed to provide a uniform flow of air through the grains to ensure that they are dried evenly. While this method is effective, it consumes significant amounts of heat and electrical energy during the process, resulting in high operational costs, more energy consumption and time consumption.
[0004] Hence, there is a need for an improved air handling system and method for a grain dryer which addresses the aforementioned issue(s).
OBJECTIVE OF THE INVENTION
[0005] An objective of the invention is to provide an air handling system to remove moisture from the grains.
[0006] Another objective of the innovation is to increase the rate of drying and reduce the drying time.
[0007] Yet, another objective of the innovation is to achieve this increased rate of drying using a non-heating method.
[0008] An additional objective of the innovation is to utilize an air handling system to increase the rate of drying.

[0024] Embodiments of the present disclosure relate to an air handling system to remove moisture from the grains is provided. The air handling system includes a housing structure configured to provide support and protection to a plurality of components positioned within the housing structure. The plurality of components includes a polygonal chamber including an air blower. The air blower is configured to generate a laminar air flow by rotating one of a fan and an impeller based on Laminar airflow module (LAM) technology. One of the fan and the impeller is positioned inside the air blower. The direction of the laminar air flow is determined by the position of the air handling system on the grain dryer. The air handling system includes an open surface on the polygonal chamber mechanically coupled to the air blower. The open surface is configured to transfer the generated laminar air flow through a heat exchanger, facilitating positive or negative pressure drying. The heat exchanger is positioned on an inner side of the open surface. The heat exchanger heating the laminar air flow before it enters for drying the grains. The air handling system includes a plurality of louvers arranged on an opposite surface to the open surface. The louvers arranged positioned inside a drying chamber of the grain dryer. The plurality of louvers is configured to suck the laminar air flow into the drying chamber by adjusting the inclination of the plurality of louvers automatically to regulate the laminar air flow rate into the drying chamber. The air handling system includes a variable frequency drive operatively coupled to the air blower. The variable frequency drive is configured to control the laminar air flow rate.
[0025] FIG. 1 is a block diagram representation of an air handling system (100) for a grain dryer in accordance with an embodiment of the present disclosure. The air handling system (100) is used to circulate and control the temperature and humidity of the air that is used to dry the grains in the grain dryer (not shown in FIG. 1). The air handling system (100) includes a housing structure (108) to provide support and protection to a plurality of components positioned within the housing structure (108). The housing structure (108) is made of heat-resistive material. Examples for heat-resistive material include but not limited to stainless steel, ceramic, aluminum and the like. The grain dryer is a machine that is used to dry grains, such as wheat, rice, corn, barley, oats, soybeans, and the like. It works by removing moisture uniformly from the grains to a desired level without altering the quality of the grains.
[0026] Further, the plurality of components positioned within the housing structure (108) includes a polygonal chamber (105). Furthermore, the polygonal chamber (105) includes an air blower (120). The air blower (120) is configured to generate a laminar airflow by rotating one of a fan (not shown in FIG. 1) and an impeller (not shown in FIG. 1) based on Laminar airflow module (LAM) technology. The fan and the impeller is positioned inside the air blower (120). A motor (not shown in FIG. 1) is attached to the air blower (120) and is adapted to provide the required power to drive the fan and the impeller. Laminar airflow is a type of airflow in which air particles move in parallel layers, without crossing over or mixing with each other while traveling. This type of airflow is characterized by a uniform velocity and direction. The direction of the laminar air flow is determined by the position of the air handling system on the grain dryer. A blowing side of the air handling system is connected to the grain dryer, the laminar air flow direction is considered positive. A suction side of the air handling system is connected to the grain dryer, the laminar air flow direction is considered negative.
[0027] In an embodiment, the air handling system (100) may include a dapper with filter. The dapper may be used in conjunction with the filter to control the direction and quality of the airflow. The damper with filter initially sucks the air from a surrounding environment and filters before it enters the air blower (120). Typically, the damper captures all types of impurity particles, and ensures that the air is clean and free from contaminants. The dapper with filter is positioned on the top of the polygonal chamber, from where the air is entering to the air handling system (100).
[0028] The air handling system (100) includes an open surface (122) on the polygonal to transfer the generated laminar air flow through a heat exchanger (124) to facilitate positive or negative pressure drying. The heat exchanger (124) is positioned on an inner side of the open surface (122). The heat exchanger (124) is adapted to heat the laminar air flow before it enters the grain dryer for drying the grains.
[0029] In an embodiment, a steam heat exchanger (124) with fin tubes is used as heat exchanger. The steam flows through the fin tubes and heats the fins, which in turn heats the laminar air that is blown over the steam heat exchanger to dry the grains.
[0030] The air handling system (100) includes a plurality of louvers (126) arranged on an opposite surface to the open surface (122). The plurality of louvers (126) is arranged inside a drying chamber (128) of the grain dryer. The plurality of louvers (126) is configured to suck the laminar air flow from the open surface into the drying chamber (128) by adjusting the inclination of the plurality of louvers (126) automatically to regulate the laminar air flow rate into the drying chamber (128). Consequently, the date of drying of the grains is enhanced. Typically, the rate of drying is defined as the mass of moisture removed from the grain in unit time. It further considers parameters such as the psychrometric conditions of the humid air at drier inlet and outlet, the initial and final moisture content of the grain, the bulk grain porosity, the grain depth, and the heat and mass transfer coefficients. Therefore, by considering the parameters into account, the air handling system is adapted to be efficient and reduces the drying time and increases the rate of drying without using a heating method.
[0031] In embodiment, the inclination of the plurality of louvers (126) is adjusted semi- automatically to regulate the laminar air flow rate into the drying chamber (128).
[0032] The air handling system (100) may be used for both positive pressure drying and negative pressure drying. In a positive pressure drying, the heated laminar air is pushed into the drying chamber (128), increasing the air pressure inside the drying chamber (128). The drying chamber (128) loads the grains for drying. The drying chamber (128) further allows the hot laminar air flow to pass through the grains, thereby removing moisture from the grains. The positive pressure drying helps to prevent dust and other particles from entering the drying chamber (128). It also improves the drying efficiency.
[0033] In a negative pressure drying, the heated laminar air flow is drawn into the drying chamber (128), creating a vacuum effect that pulls the moisture out of the grain. This may also remove moisture content from the grains.
[0034] Depending on the type of drying environment, the present disclosure describes two different approaches for drying the grains. In one approach, a positive air handling system drying approach, the laminar air flow is forced into the drying chamber (128) at a higher pressure than the surrounding environment. This creates a positive pressure drying environment inside the drying chamber (128). In the positive air handling system drying approach the blowing side of the air handling system is connected to the grain dryer, and the laminar air flow direction is considered positive. In another approach, a negative air handling system drying approach, where the suction side of the air handling system is connected to the grain dryer, the laminar air flow direction is considered negative. This creates a negative pressure environment by drawing air out of the drying chamber (128).
[0035] The air handling system (100) includes a variable frequency drive (130) operatively coupled to the air blower (120). The variable frequency drive (130) is configured to control the laminar air flow rate.
[0036] The grain dryer includes an air duct exhaust side. The air duct exhaust side (not shown in FIG. 1) is configured to expel the laminar air flow after passing through the grains in the drying chamber (128). The grain dryer further includes a discharge chamber to remove dried grains from the drying chamber (128).
[0037] FIG. 2(a)-FIG. 2(e) are sectional views of a positive air handling system of FIG. 1 in accordance with an embodiment of the present disclosure. The sectional view includes five different views: a top view FIG. 2(a), left-side view FIG. 2(b), front view FIG. 2(c), right-side view FIG.2(d), and isometric view FIG. 2(e) of the positive air handling system. An air blower (120) is housed within a protective structure, and a motor is attached to the air blower (120) to provide the necessary power to drive either a fan or an impeller that is located inside the air blower (120) (as shown in FIG. 2(c)). When the motor is turned on, the fan or impeller rotates to generate a laminar airflow using Laminar airflow module (LAM) technology. This laminar airflow is then directed towards a drying chamber (128) (also shown in FIG. 2(c)), where it will be used to dry grains in a positive pressure environment.
[0038] FIG. 3(a)-FIG. 3(e) are sectional views of a grain dryer with positive air handling system of FIG.2(a)-FIG. 2(e) in accordance with an embodiment of the present disclosure. The sectional view may include a top view as shown in FIG.3(a), left-side view as shown in FIG.3(b), front view as shown in FIG.3(c), right-side view as shown in FIG.3(d), and an isometric view as shown in FIG.3(e) of the grain dryer with the positive air handling system. The grain dryer with positive air handling system includes a positive pressure environment with a drying chamber (128) loaded with grains. The heated laminar air flow generated by the air blower (120), after passing through a heat exchanger (124), is pushed into the drying chamber (128) to increase the air pressure. The plurality of louvers (126) positioned inside the drying chamber (128) are adjusted to regulate the laminar air flow rate into the drying chamber (as shown in FIG.3(b)).
[0039] FIG. 4(a)-FIG. 4(e) are sectional views of a negative air handling system of FIG.1 in accordance with an embodiment of the present disclosure.

Like a positive air handling system, the negative air handling system includes a housing structure (108) that protects a fan or impeller which is driven by a motor. The negative air handling system generates a laminar airflow in a negative pressure environment. When the motor is turned on, the fan or impeller inside the air blower (120) rotates to generate the laminar airflow. The negative pressure environment in a drying chamber (128) allows the moist air to be extracted from the drying chamber, which helps to speed up the drying process. The moist air is then directed to the outside of the dryer (as shown in FIG.4(a)).
[0040] FIG5(a)-FIG. 5(e) are sectional views of a grain dryer with negative air handling system of FIG. 4(a)-FIG. 4(e) in accordance with an embodiment of the present disclosure. The Sectional view may include a top view as shown in FIG.5(a), left-side view as shown in FIG.5(b), front view as shown in FIG.5(c), right-side view as shown in FIG.5(d), and an isometric view (FIG.5(e)) of the grain dryer with the positive air handling system. The grain dryer with the positive air handling system creates a negative pressure environment in the drying chamber. The moist air is extracted from the drying chamber (128) using an air blower (120) and is directed to the outside of the dryer.
[0041] In accordance with an embodiment of the present disclosure, an air handling system (100) and method for a grain dryer is provided. The air handling system (100) includes a housing structure (108) configured to provide support and protection to a plurality of components positioned within the housing structure (108). The plurality of components includes a polygonal chamber (105) including an air blower (120). The air blower (120) is configured to generate a laminar air flow by rotating one of a fan and an impeller based on Laminar airflow module (LAM) technology. One of the fan and the impeller is positioned inside the air blower (120). The direction of the laminar air flow is determined by the position of the air handling system on the grain dryer. The air handling system (100) includes an open surface (122) on the polygonal chamber mechanically coupled to the air blower (120). The open surface (122) is configured to transfer the generated laminar air flow through a heat exchanger (124), facilitating positive or negative pressure drying. The heat exchanger (124) is positioned on an inner side of the open surface (122). The heat exchanger (124) heating the laminar air flow before it enters for drying the grains. The air handling system (100) includes a plurality of louvers (126) arranged on an opposite surface to the open surface (122). The louvers arranged positioned inside a drying chamber (128) of the grain dryer. The plurality of louvers (126) is configured to suck the laminar air flow into the drying chamber (128) by adjusting the inclination of the plurality of louvers (126) automatically to regulate the laminar air flow rate into the drying chamber (128). The air handling system (100) includes a variable frequency drive (130) operatively coupled to the air blower (120). The variable frequency drive (130) is configured to control the laminar air flow rate.
[0042] FIG. 4 illustrates a flow chart representing the steps involved in an air handling method (300) for a grain dryer in accordance with an embodiment of the present disclosure. The method includes providing, by a housing structure, support and protection to a plurality of components positioned within the housing structure in step 310. The grain dryer is a machine that is used to dry grains, such as wheat, rice, corn, barley, oats, soybeans, and the like. It works by removing moisture from the grains to a desired level which preserves the quality of the grains. The air handling system is used to circulate and control the temperature and humidity of the air that is used to dry the grains.
[0043] The method includes generating, by an air blower, a laminar air flow by rotating one of a fan and an impeller based on laminar airflow module technology. One of the fan and the impeller is positioned inside the air blower. The direction of the laminar air flow is determined by the position of the air handling system on the grain dryer in step 320. In Laminar airflow module technology, air particles move in parallel layers, without crossing over or mixing with each other. This type of airflow is characterized by a uniform velocity and direction.
[0044] The method includes transferring, by an open surface on the polygonal chamber, the generated laminar air flow through a heat exchanger, facilitating positive or negative pressure drying. The heat exchanger is positioned on the inner side of the open surface. The heat exchanger heating the laminar air flow before it enters for drying the grains in step 330. In an embodiment, a steam heat exchanger with fin tubes is used as heat exchanger. The steam flows through the fin tubes and heats the fins, which in turn heats the laminar air that is blown over the steam heat exchanger. The hot laminar air flows for drying the grains.
[0045] The method includes sucking, by a plurality of louvers, the laminar air flow into a drying chamber of the grain dryer by adjusting the inclination of the plurality of louvers automatically to regulate the laminar air flow rate into the drying chamber in step 340.
[0046] In positive pressure drying, the heated laminar air is pushed into the drying chamber, increasing the air pressure inside the drying chamber. The drying chamber loads the grains for drying. The drying chamber further allows the hot laminar air flow to pass through the grains, thereby removing moisture from the grains. In negative pressure drying, the heated laminar air flow is drawn into the drying chamber, creating a vacuum effect that pulls the moisture out of the grain. This may also remove moisture content from the grains.
[0047] Depending on positive or negative pressure drying environment, there are two different approaches for drying the grains. In one approach, a positive air handling system drying approach, the laminar air flow is forced into the drying chamber at a higher pressure than the surrounding environment. This creates a positive pressure drying environment inside the drying chamber (128). In a positive air handling drying approach, where the blowing side of the air handling system is connected to the grain dryer, and the laminar air flow direction is considered positive. Likewise, in a negative air handling system drying approach, where the suction side of the air handling system is connected to the grain dryer, the laminar air flow direction is considered negative. This creates a negative pressure environment by drawing air out of the drying chamber.
[0048] The method includes controlling, by a variable frequency drive, the laminar air flow rate in step 350.
[0049] Various embodiments of the air handling system and method for a grain dryer as described above uniformly drying the grains in a grain dryer using Laminar airflow module technology in the air handling system. The Laminar airflow module technology allows for a more efficient and rapid drying process. The laminar airflow is characterized by a uniform velocity and direction, which enables it to pass through the grains more effectively, thereby reducing the drying time. The air handling system uses a non-heating method to increase the rate of drying. The heated laminar airflow generated by the system's heat exchanger facilitates positive or negative pressure drying without requiring additional heat sources. This non-heating method of drying saves energy and reduces operating costs. The air handling system uses an installable air blower unit than standalone DIDW blowers to enhance the rate of drying.
