I. Process flow chart

  1. Bubble Washing:
    Dates are initially washed in a bubble washing system to remove impurities, dust, and any foreign particles.
  2. Brush Washing:
    After bubble washing, the dates may undergo brush washing to further clean and remove any remaining debris.
  3. Sorting:
    The washed dates are sorted to remove any damaged or unripe fruits. This step ensures that only high-quality dates proceed to the next stages.
  4. Steaming:
    Dates are steamed to soften them, making it easier to extract juice and create a smoother paste.
  5. Elevator:
    Steamed dates are lifted using an elevator to the next processing stage.
  6. Pulping:
    The softened dates are pulped, breaking them down into a paste-like consistency.
  7. Date Paste:
    The pulped dates are further processed into a date paste, which serves as the base for syrup production.
  8. Juice Extraction:
    The date paste undergoes juice extraction to obtain the liquid component of the dates.
  9. Decanter Separating:
    The extracted juice is processed through a decanter to separate any solid particles, obtaining a clearer liquid.
  10. Balance Tank:
    The separated liquid is collected in a balance tank, helping maintain a consistent flow for further processing.
  11. Vacuum Evaporation:
    The liquid is subjected to vacuum evaporation, reducing its water content and thickening it into a concentrated syrup.
  12. Dates Syrup:
    The concentrated liquid becomes dates syrup, rich in flavor and sweetness.
  13. Filling and Packing:
    The final dates syrup is filled into containers and packed for distribution. This can include bottles, jars, or other suitable packaging based on the intended market.

It’s important to note that specific details of each step may vary based on the scale of production, the equipment used, and the desired characteristics of the final product. Additionally, quality control measures should be implemented at each stage to ensure the production of high-quality date syrup.
