DETAILED DESCRIPTION OF THE INVENTION

[0004] Conventional biodiesel reactors suffer from inadequate heat control, inefficient mixing, alcohol loss, problems with catalyst handling, and high energy consumption, which limits process efficiency and scalability.

[0005] To overcome the aforementioned limitations, the present disclosure provides an integrated, jacketed batch reactor stirrer for biodiesel production. The device includes a reactor jacket that defines a reaction chamber for the transesterification of neem oil with methanol using a heterogeneous catalyst based on agricultural waste. A cooling jacket surrounding the reactor jacket enables controlled temperature regulation, while a heating coil ensures precise heat input. A motor-driven stirring mechanism ensures uniform mixing of the reactants and the catalyst. A condenser is mounted in the upper section to minimize methanol loss through vapor condensation. The reactor further includes a feedstock inlet and a product outlet for batch operation.The entire setup is mounted on a stable stand, enabling energy-efficient, reliable and scalable biodiesel production with improved process control.

[0006] Fig. Figure 1 shows a front view of an operationally efficient, double-walled batch reactor agitator 100 for biodiesel production. The device includes a vertically mounted, motor-driven agitator positioned at the top to enable rotary mixing within the reactor. A feedstock inlet 102 is provided on the reactor shell for the controlled introduction of neem oil, methanol, and catalyst into the reaction chamber. The reactor shell is held upright by a stand to ensure mechanical stability during operation. A product outlet 104 is located in the lower section of the reactor shell to discharge the reaction mixture after completion of the transesterification process. The front view illustrates the axial alignment and compact, vertically oriented configuration, which is suitable for the controlled batch processing of biodiesel.

[0007] Fig. Figure 2 shows a left-side view of the operationally efficient stirring device 100 for a jacketed batch reactor, illustrating the vertical arrangement of its components. An upper motor assembly 204 is mounted above the reactor to drive the internal stirring motion. A feedstock inlet 202 is provided on the reactor jacket for introducing neem oil, methanol, and catalyst into the reaction chamber. A heating coil 206 is arranged in thermal contact with the reactor jacket 208 to supply controlled heat. The reactor jacket is surrounded by a cooling jacket 210, configured to regulate the reaction temperature by circulating a temperature-regulating fluid. The reactor unit is supported by a rigid stand, which ensures stability during batch operation and provides a compact, thermally regulated configuration suitable for controlled transesterification.

[0008] Fig.Figure 1 shows an isometric view of an operationally efficient stirring device 100 for a double-walled batch reactor, illustrating the three-dimensional arrangement of its components. The view shows a motor-driven assembly mounted on a top cover of the reactor, with a condenser bracket 302 positioned on an upper section to support a condenser as a control element for methanol vapors. A cooling jacket 210 surrounds the reactor jacket to enable temperature control within the reaction chamber. The reactor assembly is supported by a stand 304, which maintains the device in a stable, upright position during operation.The isometric view illustrates the spatial relationship and integrated configuration of the motor assembly, reactor jacket, cooling jacket, condenser mount and stator, demonstrating a compact design suitable for batch production of biodiesel.

[0009] Although the implementation of a system and process for biodiesel production using a heterogeneous catalyst based on agricultural waste has been described with respect to certain structural features and operational aspects, it should be noted that the attached claims are not necessarily limited to the specific components or configurations described.
