MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611009764 A) filed by Swami Vivekananda Subharti University, Meerut, Uttar Pradesh, on Jan. 30, for 'method, and system for liquid concentration using peltier-based thermal control and sample rotation without vacuum.'
Inventor(s) include Dr Dharmendra Kumar; and Prof. Pramod Kumar Sharma.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention involves a liquid concentrator that uses Peltier-based thermoelectric control and integrated sample rotation for vacuum-free evaporation and condensation of liquid samples. The concentrator comprises a single processing chamber with thermal sensors, a dual-mode Peltier module to heat and cool simultaneously, and a rotational module that provides uniform temperature distribution without localized overheating. Using instantaneous sensor feedback to determine dynamic temperature gradient control with dynamic rotation frequency adjustment, the system establishes a controlled evaporation-condensation cycle without the need for external vacuum pumps, chillers, or compressors. A gravity-assisted solvent recovery device captures condensed vapor to provide environmentally friendly solvent reuse options. It also features digital monitoring, alert generation, and data logging to ensure safe and accurate concentration of heat-sensitive materials like natural extracts, biological samples, and analytical formulations. This invention provides a low-cost, portable, and energy-efficient substitute for traditional vacuum-based concentrators."
