TS 9591

TS 9591 addresses the general rules for liquid vegetable oil factories and provides a common framework for how this type of production facility is arranged and operated. Vegetable oil production typically involves raw material receiving, cleaning, pressing or extraction, refining, storage, and filling, so the technical and hygienic condition of the plant is important to product quality.

Plant layout and production flow

This standard covers the general rules for liquid vegetable oil factories, focusing on the functional arrangement of production areas, the prevention of cross-contamination between process steps, and the coordination of auxiliary spaces with production. In broader technical practice, facilities for oil processing depend on suitable machinery, cleanable surfaces, proper storage conditions, and an orderly process flow to handle raw materials and finished product safely and efficiently.

Scope boundaries

• Factories producing margarine are outside the scope of this standard.
• General rules for facilities producing animal fats are not included.
• This listing represents a withdrawn edition of TS 9591; the subject remains the general rules for liquid vegetable oil factories.

In practical terms, a standard of this kind helps define the expected organization of a plant, not just the machinery within it. In vegetable oil technology, the separation of crude oil and refined oil, together with tanks, piping, and filling lines, has a direct effect on product flow, quality preservation, and operating efficiency.
