Self Heating Packaging Technology for Ready to Consume Milk
Current ready-to-consume milk packaging requires external heat sources or microwave access, limiting consumption scenarios and potentially compromising milk quality. Traditional heating methods can lead to uneven temperature distribution, with surface temperatures reaching 65°C while core regions remain cold, creating both safety risks and diminished drinking experience.
The fundamental challenge lies in developing self-heating mechanisms that maintain uniform temperature distribution while ensuring food safety and packaging integrity throughout the heating cycle.
This page brings together solutions from recent research—including non-contact electric heating systems with conductive liquid isolation, integrated DC-powered heating elements with external activation, and USB-enabled temperature control interfaces. These and other approaches focus on creating practical, safe, and user-friendly solutions for on-demand milk heating that maintain consistent quality across varying consumption scenarios.
1. Milk Heating Device with Non-Contact Electric Heating and Conductive Liquid Isolation System
Guangdong Duomi Electrical Technology Co., Ltd., GUANGDONG DUOMI ELECTRIC APPLIANCE TECHNOLOGY CO LTD, 2018
A hot milk device for heating milk or breast milk that eliminates the need for direct contact between the milk container and heating element. The device features an electric heating component, a conductive liquid, an isolation bag, a heating element, and a conductive liquid installed in the isolation bag. The isolation bag provides thermal insulation while maintaining the milk's integrity, eliminating the need for water-soaked packaging. The device enables safe and convenient heating of milk or breast milk without the inconvenience of paper packaging and water residue.
2. Milk Carton with Integrated Electric Heating Element and External Activation Switch
XIAOCONG MEI, Mei Xiaocong, 2015
A heating milk carton that enables rapid warming of milk without the need for manual intervention. The carton features a hollow base containing an electric heating element, which is powered by a DC power supply. The heating element is integrated into the carton's body, eliminating the need for external heating sources. The carton's design includes a built-in heating element that can be activated by a switch located on the carton's exterior. This automatic heating system ensures that milk is consistently warmed to the desired temperature, eliminating the need for manual intervention.
3. Milk Carton with Integrated Heating Element and USB-Enabled Control Interface
Hunan Nanshan Pastoral Co., Ltd., HUNAN NANSHAN ANIMAL HUSBANDRY CO LTD, 2015
Autonomous milk cartons with integrated heating and dispensing capabilities through USB connectivity. The cartons utilize a proprietary heating element integrated into the carton design, allowing for automatic temperature control and precise milk heating. The cartons also feature a USB-enabled interface for remote monitoring and control of the heating element, enabling users to schedule and automate milk heating sessions.
