Process flow and operation points of extraction tank equipment used in cumin essential oil

Cumin seeds, known for their strong aroma, have been used as a seasoning for over 2,000 years. They are primarily used to season meat products but are also used in pickles, sauces, jams, and cheeses. Cumin is a key ingredient in soups, stews, roasted meats, and is indispensable for Xinjiang grilled skewers.

**Main Equipment:**

- Steamer

- Grinder

- Extraction equipment

- Filling machine

**Process Flow:**

1. **Grinding:**

- Grind cumin seeds into a 40-mesh powder.

2. **Distillation:**

- Add 3–4 times the amount of water to the cumin powder for distillation. The water amount significantly affects the oil yield. Too little water can cause overheating and carbonization, while too much water increases oil loss. Distillation under normal pressure for 4 hours yields about 4.5% essential oil.

**Quality Standards:**

- Cumin essential oil is light yellow with a distinct cumin aroma.

**Precautions:**

1. Avoid over-distilling, as it can cause the loss of low-boiling point components, reducing oil quality and wasting energy.

2. To make cumin essential oil, mix 2 kg of essential oil with 98 kg of vegetable oil. For spicy cumin oil, add chili or pepper oil. This oil can be used in various dishes or cold dishes.
