Dried potatoes and other dried vegetables

1. Scope and Applicability

This PCR covers the factory production of dried potatoes and other dried vegetables represented by the exact CPC-classified Tiangong product flow Dried Vegetables. It applies to vegetables dried from a succulent state by one declared artificial-dehydration route, including freeze-drying, or by one declared route combining sun-drying with artificial dehydration. Products may be whole or cut into a declared form. Each foreground data package shall preserve the vegetable identity, product form, incoming and finished-product moisture basis, pretreatment, drying technology, packaging state, and net-mass basis.

The PCR does not treat incompatible drying technologies as one interchangeable route. A dataset shall represent one declared route and technology configuration. A production mix may be constructed only from separately modelled route datasets with documented production shares; it shall not merge route-specific inventories into a single unqualified unit process.

Excluded products are potato flour, meal, powder, flakes, granules, and pellets classified separately from CPC 21393; vegetables preserved principally by freezing, vinegar or acetic acid, sugar, canning, fermentation, or another non-drying method; ready-made meals; dried fruits; cereal grains; mature dried pulses and legumes; dried spices; and products whose vegetable identity or drying route is not declared. Downstream distribution, preparation, consumption, and end-of-life are outside this foreground factory-gate dataset, although a downstream lifecycle model shall add them when required by its goal and scope.
