(1) The heating form is divided into:
1 Indirect heating type rice cooker, the structure is divided into three layers of inner pot, outer pot and pot body. The inner pot is used to hold food, and the outer pot is used to install electric heating elements, thermostats and timers. These electrical components are fixedly mounted on the outer pot and are sealed and sealed. The outermost layer is the pot body, which plays the dual role of safety protection and decoration. The advantage of the rice cooker is that the food is heated evenly, the rice is made up and down, the inner pot can be removed, and the cleaning is convenient; the disadvantage is: the structure is complicated, time consuming, and power consumption is high.
2 Direct heating rice cooker: This rice cooker is characterized in that the electric heating element directly heats the inner pot of the food when in use. Unlike indirect heated rice cookers, the electric heating element heats the water in the outer pot into steam, which in turn heats the food in the inner pot. Therefore, its high efficiency, saving time and power, the disadvantage is that the rice is easy to get up and down inconsistent.
2. From the structural form, there are:
1 Combination rice cooker, there is no fastening connection between the pot body and the electric heating seat, the pot body is placed on the electric heating seat, which can be conveniently removed, which is convenient for cleaning, and can be placed on other heating bodies or on the dining table.
2 integral rice cooker, the electric heating element is directly fixed at the bottom of the pot body, and the whole pot is formed into a whole. Due to the different structure of the pot, the integrated rice cooker can be divided into a single-layer rice cooker, a double-layer rice cooker and a three-layer rice cooker.
3. According to the control method:
1Insulation type, press the power switch when cooking, the power will be automatically disconnected after cooking, when the temperature drops to SMarttags"/>PE="1"TCSC="0"w:st="on">65°C The heat-insulating switch is connected to the circuit again. When the temperature rises to 65 °C, the power supply is automatically disconnected, so that the alternating current is turned on and off to achieve the purpose of heat preservation.
2 Start the insulation type regularly, put the rice and water in the pot, open the timer switch, and start cooking time within 12h. After the rice is cooked, it can be automatically insulated to save energy.
3 computer-controlled, using a computer for program control, so that the rice cooker's work automation program is higher.
The pot material of the rice cooker is ceramic, enamel, aluminum alloy and stainless steel. The inner wall of the inner pot is usually sprayed with a layer of PTFE anti-coke coating, which makes it difficult to paste when cooking and easy to clean.
Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable Welding Neck Flanges.
Lap joint flange is having two components, a stub end, and a loose backing flange. Stub end is butt welded to the pipe and Backing flange freely move over the pipe. The backing flange can be of different material than stub material and normally of the carbon steel to save the cost. Lap flange is used where frequent dismantling is required, and space is constrained.
Furthermore, a standard lap joint flange will typically have a longer hub length in comparison to a slip on flange, but this is often considered unnecessary for many applications.
The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face.
