This automated system efficiently handles key steps such as peeling, chopping, drying, carbonizing, grinding, and mixing the processed materials. By optimizing each stage, the device ensures a high level of precision and consistency, making it ideal for large-scale applications in dye removal.

[0022] Referring to Figure 1, an isometric view of a banana stem-based dye removal agent preparation device is illustrated, comprising a housing 101 positioned on a ground surface and installed with a platform 102 to be placed with banana stems, a touch enabled screen 103 installed on the housing 101, an artificial intelligence-based imaging unit 104 mounted within the housing 101, a pair of robotic arms 105 arranged within the housing 101, a hopper 106 arranged within the housing 101, plurality of motorized rollers 107 installed with side walls of the hopper 106, a blade 108 installed at bottom portion of the hopper 106, a motorized cutter 109 hinged at the bottom portion of the hopper 106, a water chamber 110 positioned underneath the housing 101, a strainer 111 installed within the chamber 110 via a motorized slider.

[0023] Figure 1 further illustrates an incubation container 112 positioned alongside the chamber 110, a first heating unit 113 configured with the container 112, an air blower 114 installed within the container 112, a furnace 115 arranged underneath the container 112, a second heating unit 116 integrated with the furnace 115, a vessel 117 installed underneath the furnace 115, a receptacle 118 configured with the vessel 117, a motorized grinder 119 installed in the vessel 117, a cylindrical body 120 installed underneath the vessel 117, a canister 121 stored with starch solution and configured with the body 120, a motorized agitator 122 configured with the body 120, a mould 123 arranged underneath the body 120 and carved with slots, a Peltier unit 124 configured with the mould 123 and a speaker 125 mounted on the housing 101.

[0024] The proposed device herein comprises of a housing 101 developed to be positioned on a ground surface and installed with a platform 102 to be placed with banana stems. The housing 101 is constructed from a durable material such as, but not limited to stainless steel, aluminum alloys, reinforced polymers or high-strength composites. These materials are selected to ensure the housing 101 provides sufficient mechanical strength and rigidity to withstand the cumulative weight of the internal components and external forces during operation.

[0025] A user is required to press a push button integrated with the device, such that when the user presses the push button, it initiates an electrical circuit mechanism. Inside the push button, there is a spring-loaded contact mechanism that, under normal circumstances, maintains an open circuit. When the button is pressed, it compresses the spring, causing the contacts to meet and complete the circuit. This closure then sends an electrical signal to an inbuilt microcontroller associated with the device to either power up or shut down. Conversely, releasing the button allows the spring to return to its original position, breaking the circuit and sending the signal to deactivate the device.

[0026] The user accesses a touch enabled screen 103 installed on the housing 101 for enabling a user to give input commands for preparing banana stem-based dye removal agent from the banana stems. The touch enabled screen 103 consists of multiple layers, including a transparent conductive layer such as indium tin oxide (ITO) coated glass, which forms the surface that users directly touch. Beneath the layer lies a grid of electrodes, typically made of a conductive material like copper or silver, arranged in rows and columns.

[0027] When the user touches the screen 103, it creates a measurable change in capacitance at the point of contact, altering the electrical field between the electrodes. This change is detected by the controller circuitry embedded within the screen 103, which interprets the position and intensity of the touch. The controller then converts this data into digital signals representing user inputs, which are further processed by an inbuilt microcontroller associated with the device.

[0028] The microcontroller processes the user’s input commands to activate an artificial intelligence-based imaging unit 104 mounted within the housing 101 for detecting presence of banana stems on the platform 102. The imaging unit 104 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the platform 102, and the captured images are stored within a memory of the imaging unit 104 in form of an optical data.

[0029] The imaging unit 104 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and detecting presence of banana stems on the platform 102.

[0030] On detection of banana stems, the microcontroller actuates a pair of robotic arms 105 arranged within the housing 101 for picking and transferring the stems one-by-one in hopper 106 arranged within the housing 101. The robotic arm 105 is able to perform the designated task with high efficiency and accuracy, wherein the robotic arm 105 consists of mechanical joints and actuators, which are controlled by the microcontroller. The actuators allow various degrees of freedom and movement and the joints are actuated by a DC (Direct Current) motor, providing the necessary force and motion to pick and transfer the stems one-by-one in hopper 106.

[0031] once the stems are placed in the hopper 106, the microcontroller actuates plurality of motorized rollers 107 installed with side walls of the hopper 106 to rotate for pushing the stem against a blade 108 installed at bottom portion of the hopper 106 such that stem is peeled. The motorized roller 107 consists of a cylindrical body 120 mounted on a shaft connected to an electric motor. The motor generates torque, causing the shaft and roller 107 to rotate. The rollers 107 are arranged parallel to each other within the hopper’s 106 side walls and are powered in synchronization to ensure consistent motion. As the rollers 107 rotate, the friction between their surface and the banana stem propels the stem toward the blade 108 installed at the bottom. This controlled movement ensures the stem is precisely positioned and peeled effectively.

[0032] The microcontroller synchronously actuates a motorized cutter 109 hinged at the bottom portion to chop the peels. The cutter 109 is powered by a DC (direct current) motor that is capable of converting the electric current provided from an external force into mechanical force for providing the required power to the cutter 109, thus chopping the peels and the chopped peel pieces are collected in a water chamber 110 positioned underneath the housing 101 for cleaning of the chopped pieces.

[0033] A strainer 111 is installed within the chamber 110 via a motorized slider that is actuated by the microcontroller to translate the strainer 111 towards mouth portion of the chamber 110. The motorized slider includes sliding rack and rail, such that the strainer 111 is mounted over the racks that are electronically operated by the microcontroller for moving over the rails. The slider is powered by a DC (direct current) motor that is actuated by the microcontroller by providing required electric current to the motor. The motor comprises of a coil that converts the received electric current into mechanical force by generating magnetic field, thus the mechanical force provides the required power to the rack to provide sliding movement to the strainer 111 towards mouth portion of the chamber 110.

[0034] The microcontroller then actuates a motorized pivot joint configured between the slider and strainer 111 for flipping the strainer 111. The pivot joint is a mechanical component that allows rotary movement around a single axis, wherein the pivot joint is powered by a (Direct Current) motor that is capable of converting the electric current provided from an external force into mechanical force for providing the required power to the pivot joint for flipping the strainer 111 to transfer the pieces in an incubation container 112 positioned alongside the chamber 110.

[0035] A first heating unit 113 is configured with the container 112 that is activated by the microcontroller for maintain an optimum heat within the container 112. The first heating unit 113 consists of a coil such that as current is passed through the coil, the coil becomes hot and produces heat energy. This heat energy of the first heating unit 113 is transferred to the wire thereby heating the patterned wires. The first heating unit 113 is actuated by the microcontroller in order to regulate the temperature of the first heating unit 113 required for allowing drying of the pieces to remove moisture from the pieces for a first pre-set time duration.

[0036] The microcontroller actuates an air blower 114 installed within the container 112 for circulating hot air within the container 112. The air blower 114 consists of an impeller which creates a high-speed airflow, wherein the generated high-speed airflow from the blower 114 to circulate the hot air within the container 112 for allowing even heating of the pieces.

[0037] A first motorized iris lid is configured with the container 112 that is actuated by the microcontroller to open upon completion of the first pre-set time duration for transferring dried pieces to a furnace 115 arranged underneath the container 112. The iris lid comprises of a ring and a blade with multiple protrusions. The ring is fabricated with multiple grooves. The protrusions on the blades engage with the grooves on the ring in order to link the movement of the ring and blades. As the ring rotates, the protrusions move within the grooves to open or close the lid according to the degree of rotation of the ring. The ring is installed with the motor that is actuated by the microcontroller for rotating the ring with a specified speed to regulate the opening and closing of the lid for transferring dried pieces to the furnace 115.

[0038] The microcontroller actuates a second heating unit 116 integrated with the furnace 115 to heat the pieces to obtain carbonized pieces. The second heating unit 116 operates on the same working principle as that of the primary first heating unit 113 disclosed above, thus the second heating unit 116 heat the pieces to obtain carbonized pieces and then the microcontroller actuates a second iris lid configured with the furnace 115 to open for transferring the carbonized pieces to a vessel 117 installed underneath the furnace 115.

[0039] An electronic valve is installed with a receptacle 118 configured with the vessel 117 and stored with clay powder to open for dispensing the clay powder in the vessel 117. The electronic valve comprises of an upper body that serves to hold down all the components present inside the valve including a permanent magnet that is incorporated with a shaft, a thread, a needle, and a seat to carry out the specified function of opening and closing the valve in accordance with the user. A stepper motor equipped with copper coils is used in the electronic valve to ensure smooth movement inside the valve when the clay powder is dispensed in the vessel 117. The valve further includes a holder to hold down all the components aside from the motor and coil to maintain the longevity of the motor and is connected with the microcontroller to dispense the necessary amount of clay powder in the vessel 117.

[0040] The microcontroller then actuates a motorized grinder 119 installed in the vessel 117 to grind the carbonized pieces with the clay to obtain peel powder. The grinder 119 is linked with a DC (direct current) motor to provide the required power to the grinder 119 to move in a direction in order to provide required movement to the grinder 119. The motor comprises of a coil that converts the received electric current into mechanical force by generating magnetic field, thus providing the required power to the grinder 119 for grinding the carbonized pieces with the clay to obtain peel powder.

[0041] The microcontroller actuates plurality of iris pores installed with the vessel 117 to open for dispensing the powder to a cylindrical body 120 installed underneath the vessel 117. The iris pore works by utilizing a motor to control the movement of overlapping, curved blades that form the adjustable aperture. The motor is connected to individual linkage arms attached to the blades. When the microcontroller activates the motor, it generates rotational motion that is transmitted to the linkage arms. This motion causes the blades to move in a synchronized manner either sliding inward to decrease the aperture size or outward to increase, enabling consistent and controlled dispensing of the powder from the vessel 117 into the cylindrical body 120.

[0042] An electronic nozzle is attached with a canister 121 stored with starch solution and configured with the body 120 that is actuated by the microcontroller to open for dispensing the solution within the body 120. The electronic nozzle operates through precise control facilitated by a solenoid valve actuated by the microcontroller. When the microcontroller sends an electrical signal to the solenoid coil, it generates a magnetic field that moves the valve's armature, allowing pressurized solution to flow through the nozzle within the body 120.

[0043] The microcontroller then actuates a motorized agitator 122 configured with the body 120 to rotate for agitating the powder and solution to obtain a slurry. The motorized agitator 122 operates on the principle of rotational mixing using a motor to create a turbulent flow for homogenizing the powder and solution into a slurry. The agitator 122 consists of a central shaft connected to the motor, with blades mounted along the shaft. The motor generates rotational motion that is transferred to the shaft and blades. As the blades rotate, they create shear forces and turbulence within the mixture, ensuring thorough blending of the powder and solution to obtain uniform slurry.

[0044] The microcontroller actuates an electronic spout attached with the body 120 to open for dispensing the slurry in a mould 123 arranged underneath the body 120 and carved with slots. The spout consists of a nozzle, a valve and a motor. The nozzle is designed to guide the slurry into the mould 123 accurately, while the valve, located within the spout, controls the opening and closing to start or stop the flow. The actuator, powered by the microcontroller, generates the necessary mechanical movement to open or close the valve. When the microcontroller sends a command, the motor moves the valve, allowing the slurry to flow through the nozzle and into the mould 123 slots.

[0045] The microcontroller actuates a Peltier unit 124 configured with the mould 123 to cool the mould 123 for solidifying the slurry into multiple tablets. The Peltier unit 124 operates based on the Peltier effect, a thermoelectric phenomenon. The Peltier unit 124 consists of semiconductor materials arranged in a series of alternating n-type and p-type elements. When an electric current is applied to the elements, it results in the transfer of heat from one side of the unit to the other, creating a cooling effect on one side and a heating effect on the opposite side, thus the Peltier unit 124 cool the mould 123 for solidifying the slurry into multiple tablets.

[0046] The microcontroller activates plurality of tactile sensors integrated with the mould 123 to detect hardness of the slurry. The tactile sensor detects the hardness of the slurry by measuring the force of contact between the sensor and the slurry. The sensor is typically a small, flat component that is placed against the slurry and then pressed down. As the force of contact increases, the sensor measures the amount of pressure being applied and sends a signal to the microcontroller. The microcontroller then interprets the signal and determines the hardness of the slurry. Upon solidification of the tablets, the microcontroller activates a speaker 125 mounted on the housing 101 for notifying the user to collect the tablets from the mould 123.

[0047] An oxygen sensor is configured within the furnace 115 to detect level of oxygen in the furnace 115. The oxygen sensor consists of a ceramic substrate coated with a material such as zirconium dioxide (ZrO₂) and electrodes made of platinum. The sensor is heated to a high temperature, enabling the zirconium dioxide to conduct oxygen ions. When there is a difference in oxygen levels between the furnace 115 interior and the reference air outside, an electrochemical reaction occurs, generating a voltage across the electrodes proportional to the oxygen concentration. This voltage signal is sent to the microcontroller, which compares the detected oxygen level to a preset threshold. If the oxygen level exceeds the threshold, the microcontroller activates the motorized lid to close effectively cutting off the oxygen supply and preventing over-burning of the pieces.

[0048] Plurality of pneumatic pins are arranged within the slots that are actuated by the microcontroller to extend for pushing out the tablets from the slots. The pin is linked with to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the pin. The pneumatic unit is operated by the microcontroller. Such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the pin and due to applied pressure, the pin extends and similarly, the microcontroller retracts the pin by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension/retraction of the pin in order to push out the tablets from the slots.

[0049] The device is associated with a battery for providing the required power to the electronically and electrically operated components including the microcontroller, electrically powered sensors, motorized components and alike of the device. The battery within the device is preferably a lithium-ion-battery which is a rechargeable battery and recharges by deriving the required power from an external power source. The derived power is further stored in form of chemical energy within the battery, which when required by the components of the device derive the required energy in the form of electric current for ensuring smooth and proper functioning of the device.

[0050] The present invention works best in the following manner, where the user places banana stems on the platform 102 installed on the housing 101. The user inputs commands via the touch-enabled screen 103, which are processed by the microcontroller to activate the imaging unit 104. The imaging unit 104 detects the presence of stems and commands robotic arms 105 to pick and transfer the stems into the hopper 106. Motorized rollers 107 within the hopper 106 rotate to push the stems against the blade 108, peeling them effectively. The peels are chopped by the motorized cutter 109 and collected in a water chamber 110 for cleaning. The strainer 111 in the chamber 110 mounted on a motorized slider that moves towards the chamber’s 110 mouth and flips to transfer the peels into an incubation container 112. The first heating unit 113 and air blower 114 operate synchronously to dry the pieces by circulating hot air for a pre-set time. Once dried, the microcontroller opens the iris lid, transferring the peels to the furnace 115 where they are heated by the second heating unit 116 to carbonize them. Oxygen levels are monitored by the oxygen sensor and the motorized lid closes to prevent over-burning if oxygen exceeds the threshold. The carbonized pieces are ground with clay powder dispensed from the receptacle 118 using the motorized grinder 119. The resultant peel powder is transferred to the cylindrical body 120 where it is mixed with starch solution dispensed by the electronic nozzle. The motorized agitator 122 blends the mixture into the slurry, which is dispensed through a spout into a mould 123 with slots. The Peltier unit 124 cools the mould 123 to solidify the slurry into tablets. Tactile sensors detect tablet solidification, triggering a speaker 125 to notify the user. The microcontroller activates the pneumatic pins to eject the tablets for collection, completing the process efficiently and with minimal user intervention.
