Main technology and structural performance of electric heating stirring tank

Electric heating mixing tanks are widely used in food (dairy) products, pharmaceuticals, daily chemicals, beverages, oils, chemicals, pigments and other industries as heating, mixing and sterilization
.

It is especially suitable for small and pilot-scale use in units and scientific research institutions without steam heat source
.

And according to the needs of the process, a fully enclosed structure can be adopted
.

Main technology and structural performance of electric heating stirring tank: 1.
Volume: 50L, 100L, 200L, 300L, 500L, 600L, 1000L～5000L
.

2.
Heating method: The electric heating rod is inserted into the jacket, and the heating is even and there is no cold zone
.

The heat transfer oil or water is injected into the jacket as the heating medium to generate heat energy to heat the materials in the tank
.

3.
Material heating temperature: ≤350℃; material heating time: 20min～90min (depending on process requirements)
.

4.
Temperature control: The thermocouple is used to measure the temperature and the temperature controller is connected to measure and control the temperature (temperature difference ±≤1°C), and the temperature of the material can be adjusted
.

The temperature controller is installed in the electric control box, and the temperature transmission rod is inserted directly to the bottom of the tank, so that the temperature of the material liquid can be indicated even when it is at the lowest position
.

5.
Tank body: The inner surface is mirror polished, and the roughness Ra≤0.
28μm
.

6.
Upper cover: It is two openable movable covers, which are easy to clean.
The inner and outer surfaces are mirror polished (roughness Ra≤0.
28μm)
.

 　　7.
The bottom structure of the inner tank: It is processed into an R angle by spinning, and there is no dead angle after welding and polishing with the inner tank body
.

 　　8.
Jacket form: full jacket, used to add heat transfer oil or water to achieve better heating and cooling purposes during work
.

 　　9.
Thermal insulation material: It is filled with pearl wool, rock wool or polyurethane casting foam to maintain the temperature difference with the outside world and achieve the effect of thermal insulation
.

 　　10.
Surface treatment of the outer shell: mirror polishing or 2B primary color matt or 2B matte matte treatment
.

 　　11.
Stirring device: the top center stirs, and the output shaft of the reducer and the stirring paddle shaft are connected by a looper, which is convenient for disassembly and cleaning
.

 　　12.
Stirring speed: 15~120r/min (constant speed); stirring paddle type: frame type, anchor type, paddle type, turbine type, etc.
(according to process requirements)
.

 　　13.
Equipment configuration: electrical control box, temperature meter, material liquid inlet and outlet, medium inlet and outlet (oil inlet and outlet), vent (oil spill hole),
etc.

 　　14.
Material: the inner tank is SUS304 or SUS316L; the jacket is Q235-B or SUS304; the outer protective shell is SUS304
.

 　　15.
The openings of each inlet and outlet nozzles and the welding of the inner tank body adopt the arc transition of the flanging process, which is smooth and easy to clean without dead ends, and has a beautiful appearance
.
