Rubber is the main raw material of pressure cooker gasket, and many additives such as vulcanizing agent, antioxidant, activator, filler and colorant are used in the processing. In order to reduce the production cost, some illegal manufacturers add some non-food additives, which are easy to cause food pollution and have adverse effects on the human body during use.
Extended data:
It is best to prepare two aprons at home, one of which is dedicated to cooking oily food, which can prolong the service life of the other apron by 3 to 5 times.
In addition, during the service life of the pressure cooker, we must pay attention to the performance of the five safety components: cover, hole, valve, ring and plate.
1, lid: When closing the lid, both the upper and lower handles should be closed, and then open the lid after cooling.
2. Hole: Before use, check whether the exhaust hole is unobstructed, and the plug cover and thrust valve should be cleaned in time.
3. Valve: The pressure limiting valve shall not be used to pressurize heavy objects, nor shall it be replaced by other items. The venting of the safety valve indicates that the pressure in the pot has exceeded the pressure, so the fire source should be turned off immediately or switched to a small fire.
4. Ring: The sealing ring of the pot cover should be cleaned after each use, wetted before use, and updated immediately in case of aging, air leakage and deformation.
5. Plate: This is a safe low-melting alloy plate after strict calculation. It can never be replaced by any other metal sheet, and food residues can never be attached to the fusible sheet, so as not to affect the heat conduction.
