Frozen vegetable production lines — process chain
A frozen vegetable production line processes fresh vegetables from harvest through cleaning, cutting, blanching, cooling, freezing, and packing. The typical process stages are: receiving and inspection (incoming quality inspection of fresh vegetables); washing and cleaning (rotary drum washers, spray washers — removing field soil, insects, and surface contaminants); preparation (cutting, slicing, or dicing depending on the vegetable and the required product size); size grading (drum or roller graders to sort cut product into size grades); inspection and stone/foreign material removal (vibrating inspection conveyor); blanching (hot water or steam blanching to inactivate enzymes that cause colour and flavour deterioration during frozen storage — a critical quality step; blanch time and temperature must be optimised for each vegetable to avoid over-softening); cooling (rapid chilling after blanching to stop the cooking and reduce the product temperature before freezing); IQF freezing (fluidised bed IQF for peas, corn, and diced vegetables; belt or spiral IQF for larger pieces); metal detection; weighing and packing (into retail bags or bulk cartons); cold storage and distribution. The line must be designed for the specific vegetable species and product specification.
