In small and medium-sized heating processes such as food processing, pharmaceutical solvents, and chemical ingredient preparation, electric heating jacketed kettles, with their advantages of “instant heating, precise temperature control, and compact footprint”, are gradually replacing traditional steam jacketed kettles and becoming core equipment for small and medium-batch production. They heat the heat-conducting oil (or water) in the jacket through electric heating tubes, indirectly transferring heat to the materials in the kettle, avoiding material burning at the bottom caused by direct contact with the heat source. At the same time, they solve the problems of steam heating relying on boilers and complex pipeline laying. This article will explain the practical knowledge of electric heating jacketed kettles from four dimensions: selection, operation, maintenance, and application, helping enterprises improve heating efficiency and production safety.
1.Selection without blind following: 4 core parameters matching production requirements
When selecting products, it is necessary to require the manufacturer to provide material test reports to prevent 201 stainless steel from being used as a substitute, so as to avoid rusting of the material and contaminating the materials.
2.Volume calculation: Determine based on ‘single batch + reserved space’ to avoid overload
The effective volume of an electric heating jacketed pot is usually 70%-80% of the nominal volume (space needs to be reserved for material boiling and stirring), which needs to be calculated in combination with the daily production batch and process cycle.
3.Power matching: Determine the power based on heating speed and material boiling point to balance efficiency and energy consumption
Power determines the heating speed, which needs to be selected based on the material’s required heating time and boiling point.
4.Additional functions: Select as needed to enhance operational convenience
Select practical additional functions based on production needs and avoid paying for redundant functions:
Maintenance: 4 Key Points to Extend Equipment Life and Reduce Repair Costs
The core vulnerable parts of the electric heating jacketed pot are the electric heating tube, gasket, and temperature controller. Daily maintenance should focus on these components, which can usually extend the equipment’s service life by 2-3 years.
1.Inner Liner Cleaning: A must-do after each use to prevent material residue from causing corrosion.
2.Electric heating tube maintenance: Inspect every six months to prevent scale buildup from affecting efficiency.
3.Seal replacement: Regular inspection to prevent leakage
4.Temperature controller calibration: Calibrate quarterly to prevent temperature deviation
