Root vegetable processing Root vegetables cover a number of different products including potato, carrot, beet root, celery root and parsnip. Many of them form a nutritious and inexpensive part of the diet, and in recent years their industrial processing has become more widespread.
Cabinplant can provide complete lines for the processing of IQF root vegetables with capacities ranging from 1 to approx. 10 t/h.
A typical processing line consists of: - Reception of raw material
- Stone trap for removal of stones to avoid damage to peeling machines and slicing/dicing machines
- Washing of raw material to avoid dirt in the peelers, to improve the peeling result and to reduce machine wear
- Peeling by steam peelers or abrasive peelers
- De-skinning
- Washing of peeled roots and recirculation of water to reduce water consumption
- Manual inspection to reject roots with spots, etc.
- Slicing or dicing to improve blanching performance
- Sliver removal to reject small pieces and to improve quality of the finished product
- Accumulation to improve infeed to the blancher
- Blanching and cooling to maintain taste, colour and vitamins in the product after freezing
- Draining of water
- Scanning of roots by a colour sorter or laser scanner
- Freezing
- Grading, typically into 3 sizes
- Weighing and packing. In most cases, the roots are packed in bulk and stored in cold storage until they are ready for packing into catering packaging or retail packaging, e.g. bags.
