How does the rice cooker shell ensure that daily diets are worry-free?
Release Time : 2025-01-21
The rice cooker shell plays an important role in ensuring daily diet safety. To ensure that the plastic shell does not contaminate food or release harmful substances, manufacturers and regulators have taken a series of measures.
1. Material selection
Food-grade plastic: The plastic shell of the rice cooker is usually made of food-grade plastic materials, such as polypropylene (PP) or polyethylene (PE), which are widely recognized as safe and non-toxic and suitable for environments that come into contact with food.
BPA-free: Avoid using plastics containing bisphenol A (BPA), as BPA may have negative effects on human health. Modern rice cooker shells are usually marked as "BPA-free" to ensure consumer safety.
2. Manufacturing process
High temperature stability: The plastic shell undergoes rigorous testing during the manufacturing process to ensure that it will not deform or release harmful substances in a high temperature environment. The internal temperature of the rice cooker is high when it is working, and the plastic shell needs to be able to withstand this high temperature and remain stable.
Sealing performance: The plastic shell is tightly combined with the metal parts of the rice cooker to prevent moisture and steam from penetrating, avoiding short circuits or damage to the internal circuits.
3. Design and structure
Insulation treatment: Plastic shells usually have good insulation properties to prevent high internal temperatures from being directly transferred to the shell surface, preventing users from getting burned during use.
Anti-slip design: The shell surface may be designed with anti-slip textures to increase friction and improve stability in use.
4. Environmental considerations
Recyclability: The plastic shells of some high-end rice cookers are made of recyclable materials, which contributes to environmental protection and sustainable development.
Low VOC emissions: Choose plastic materials with low volatile organic compound (VOC) emissions to reduce the impact on indoor air quality.
In short, through comprehensive control of material selection, manufacturing process, safety standards, design structure, and precautions for use, the rice cooker shell can effectively ensure the safety of daily diet, so that consumers do not need to worry about health risks during use.
