Steam sandwich pot classification: 1, according to the structure is divided into: Tilting sandwich pot, vertical (fixed) sandwich pot structure 2, according to the heating modes: electric heating sandwich pot, steam heating sandwich pot, gas heating sandwich pan. 3, according to the needs of the process using a stirred or without stirring the pot sandwich. 4, according to process requirements adopted with ordinary mixing or stirring with a spatula. Steam heating sandwich pot safe and convenient and efficient one, safe and convenient vapor sandwich pot: pot pot layer sandwich pot (inside the pot) using acid resistant austenitic stainless steel manufacturing, with a pressure gauge and a safety valve, appearance, easy to install, easy to operate, safe and reliable. 2, the heating efficiency: sandwich pot with a certain pressure steam as the heat source (also optional electric heating), sandwich pot with a large heating area, high thermal efficiency, uniform heating, the liquid material boiling time is short, easy to control the heating temperature and so on. Steam sandwich pot Caution: 1, the use of steam pressure, shall not exceed the quota work pressure for a long time. 2, into the steam inlet valve should be opened slowly, until the required pressure has been reached, the cut-off valve at the outlet of the condensate, if fitted traps should always be valve opens; if not hydrophobic, the first valve open until steam overflow valve off small and then the opening degree maintained in a small amount of water vapor overflows. 3, safety valve, according to the user's own use of steam pressure, self-adjusting. 4, steam sandwich pot in use, should always pay attention to changes in vapor pressure, with the inlet valve adjust. 5, stop the intake, the bottom of the pot should be straight cock open mouth, is done over water. 6. Tilting sandwich pot and stirred before class use, should refuel in the rotating parts; agitating member decent sandwich pot on the pot, cooked vegetable oil is recommended; others are used throughout the 30 # - 40 # machinery oil. Steam sandwich pot maintenance: 1, inlet and outlet pipe fittings steam leakage, tighten the nut when the election does not solve the problem, you should add or replace the packing. 2, pressure gauge and safety valve should be checked regularly, if the fault timely replacement and repair. 3, after the gearbox started 50 hours, should be removed to release the oil, washed with kerosene or diesel oil, 30 # - 40 # Clean engine oil, the use of 150 hours, the second oil change, depending on the particular circumstances in the future every 1000 hours using an oil change once. 4, anti-rust oil peel, brushing should be painted outside the pot of paint, water-resistant vinyl recommended X55-3 aluminum paint. 5, steam sandwich pot after 5 years, it is recommended for safety pressure test, carried out after the hydrostatic test intervals, as required throughout the technology sector performed.
