Low-temperature reliability of the foamed material The rice cooker filled with the heat-insulating material was placed in a freezer at -20 ° C for 3 days in the refrigerator, and then recovered at room temperature for 30 minutes. Upon inspection, no significant changes were observed in the surface of the rice cooker, and no delamination was observed between the foam and the metal. High temperature aging test of the foam.

The change in thermal conductivity of the foam after two high temperature aging. The above data shows that the thermal conductivity of the foam has decreased after high temperature aging, but it is not obvious. The appearance of the rice cooker filled with the heat insulating material after one round of open aging at 180 ° C for 5 hours.

It can be seen from the above that the foam has better heat resistance and is superior to the central plastic parts which are in direct contact with the inner pot cover. The burning test of the foam (non-national standard test) directly burns the foam on the open flame and the plastic parts on the rice cooker, both of which ignite and continue to burn. The foam physical property test is known from the above data, and the foam fully satisfies the enterprise standard of "polyether compound for rice cooker and foam molding technology". Marketing staff channel consultant heating curve indicates temperature energy-saving rice cooker ordinary rice cooker time Note: Test sample: CFXB40-J56 (220V/700W) From the above test results, the foam in the rice cooker normal working state and abnormal state If there is no open flame, there will be no obvious deformation, weight loss, fire, etc. It is safer and has better heat resistance than the plastic parts used on the rice cooker.

Safety and Hygienic Performance Experiment 800 ml of distilled water was placed in a foaming rice cooker. The water was continuously boiled for 65 minutes, and the remaining water (60 ml) was shaken. The water sample was directly injected into the gas chromatograph for detection. The leftover water was detected by GC/MS, and no abnormal gas was found except for the water vapor. Thermal efficiency experiment (see 5) Thermal efficiency, insulation energy consumption 5 can be seen from 5, the thermal efficiency of the rice cooker increased by 11.4%, the energy consumption during insulation is 0W.h.

Boiled water time and temperature test (see 6) 6 boiling water time and temperature test Note: Test conditions: room temperature 19.5 ° C, water temperature 13.8 ° C, water volume 4.0 L from the above test can be seen, add insulation layer rice cooker from 13.8 The time taken to raise the temperature to 100 °C by °C is 18.02% less than that of the unheated rice cooker; and from 100 °C to 60 °C, the electric rice cooker with the insulation layer is extended by 15.24% compared with the rice cooker without the insulation layer. time. Therefore, the foamed rice cooker significantly shortens the cooking time and saves electric energy. In fact, the rice cooker changes the heating curve of the ordinary rice cooker, thereby achieving the energy saving effect.

The performance analysis uses a rigid polyurethane foam as the insulation layer between the outer casing and the inner pot cover, which greatly changes the performance of the rice cooker.

In the heat preservation stage, the amount of water loss is greatly reduced, and the rice after long-term heat preservation in the rice cooker still has a good taste. From the nutritional point of view (for this purpose, we also visited the nutrition experts of the Food Research Institute), the heating method of the starch in the rice grains is more mature, and the nutrition is more easily absorbed by the human body.
