Heating Plate of Pressure Cooker And Rice Cooker



Pressure cooker are common household appliance in every family. Without exaggerate speaking, electric pressure cooker has become more and more popular due it is getting more and more convenience and safety. Compared to the electric pressure cooker, the lid of the stove pressure cooker is easily jump up if the steam does not release completely.

Aluminum is an essential. Aluminum is the third most common metal on earth, it has great conductivity and lightweight advantages that ideal for construction to cooking appliances to auto manufacturing. Aluminum heating plate is made with aluminum alloy which combined cooper, silicon and other metallic elements. Each heating plate, there are 80% aluminum and 20% heating tube.

Rice cooker and pressure cooker are bias. Rice cooker only can cook rice, soup or water. Pressure cooker has multiple functions, such as cooking pork leg and bean in a short time. Except for their function’s differences, the structure of aluminum heating plate for each are not the same. Following are the differences between rice cooker heating plate and pressure cooker heating plate:


Both heating plates are made with aluminum metal material.

Both aluminum heating plates are a round shape with one or two heating tubes based on the voltage power requirement.

Both have a hole in the middle of the heating plate designed for thermostatic switch. Thermostatic switch is a temperature-operated switch that receives energy from the device’s thermal convection, according to the information from Encyclopedia.


Compared to rice cooker, the voltage of pressure cooker is higher where range from 800W to 1500W or more.

For the safety improvement, pressure cooker’s heating plate is complicated. For example, there are six pillars are added on the outer circle of the heating plate. These pillars are designed for setting spring and iron terminal. Spring and iron terminal are a set of spring switch when the cooking pan is being fulfill with steam pressure, the strong stress will depress down the cooking pan, the installation of spring switch avoids the cooking pan suffering the burn out situation.

Thermostatic switch is different. Thermostatic switch is setting in the core of the aluminum heating plate for either rice cooker and pressure maker. For rice cooker, the spring is being set inside the thermostatic switch. However, there are two springs are installed for pressure cooker’s thermostatic switch. One is inside the switch; the other is installed on the back of the thermostatic switch for bearing capability. Based on the information from Exploratorium, compared to rice cooker, pressure cooker has more than 15 psi atmospheric pressure. Therefore, pressure maker must add addition spring for cooker’s heavy duty.

Pressure cooker has a snap disc thermostat switch for managed thermal. Information from Alternative Heating & Supplies, snap disc thermostat switch is a mechanical thermostat that a bimetal disc controls the thermal expansion and contraction at a set temperature. Snap disc thermostat switch is a controller in order to manipulate the temperature for pressure cooker. When the temperature of every function is fixed, such as function of cooking rice and function of cooking bean, cooking temperature and time is automatic and fixed.

All in all, although aluminum heating plate of pressure cooker have different structure than rice cooker, both are efficiency and useful for every family. Gaosheng Aluminum Company, supplier and partner of Midea & Supor, expertise in manufacturing aluminum heating plate for more than 30 years. Customized aluminum heating plates are accepted.
