When evaluating a continuous candy cooker, you must prioritize production capacity (kg/h) to ensure it meets your output requirements. Key technical components include the vacuum system efficiency, which is critical for moisture removal without scorching, and PLC control systems (e.g., Siemens or Omron) for precise temperature and timing management. Look for 316L stainless steel for parts in contact with food to ensure corrosion resistance and hygiene, and verify the steam pressure rating of the heating jacket to ensure it aligns with your factory's boiler capabilities.
