Dill Extraction Plant

A dill extraction plant is a specialized facility designed to extract essential oil from the seeds and/or aerial parts (leaves and stems) of the dill plant (Anethum graveolens). Dill oil is known for its fresh, herbaceous, slightly sweet aroma and is widely used in flavoring foods, as well as in pharmaceuticals, perfumery, and aromatherapy for its digestive and calming properties.

The most common method of extraction in such a plant is steam distillation. In this process, cleaned and dried dill seeds or herb parts are placed in a distillation chamber. Steam is passed through the plant material, vaporizing the essential oil. The oil-laden steam is then cooled in a condenser, and the essential oil is separated from the water in a collection vessel. The final oil is filtered and stored in airtight, light-resistant containers to preserve its therapeutic and aromatic qualities.

Modern dill extraction plants are equipped with stainless steel distillation units, boilers, condensers, separators, and precise temperature and pressure control systems. These facilities follow GMP (Good Manufacturing Practices) and often meet food or pharmaceutical-grade standards. The two main types of dill oil are dill seed oil, which contains high levels of carvone, and dill weed oil, which is richer in compounds like limonene and phellandrene. The plant's design ensures efficient oil recovery, hygiene, and safety during production.
