What Are The Stages of Frying Onions?

What are the stages of frying onions? Depending on different production requirements, the processing flow will be different. Here we will introduce some main production processes.

1. Raw material preparation

Choose fresh onions of uniform size and intact skin. Remove dirt and impurities to ensure that the raw materials are clean.

2. Root cutting and peeling

Root cutting

Use special root cutting equipment to trim the top and bottom of the onion for subsequent processing.

Peeling

Peeling is a key step. Modern factories often use automatic peeling machines to quickly remove the onion's skin through high-pressure air, reducing manual intervention and improving efficiency.

3. Cutting

Depending on the product requirements, the onions are fed into the cutting equipment. Slicing or dicing can precisely cut the onions into the required shape and thickness, ensuring uniform specifications of the finished product.

Slicing: used to make fried onion rings.

Dicing: suitable for fried onion cubes for seasoning.

4. Breading

This step is not necessary, but some manufacturers bread their onions to add a crunchy coating or enhance flavor.

5. Deep frying

Automatic deep frying machine are usually used to ensure that the oil temperature is stable, usually between 160°C-180°C, for the best frying results. The onions are evenly fed into the machine during the frying process. The onions are quickly fried at high temperatures, the water is evaporated, and the surface becomes golden and crispy. After frying, excess oil is removed by de-oiling equipment to improve the taste and health attributes of the product.

6. Cooling and Packaging

After frying, the onions are cooled by cooling belts to avoid moisture accumulation or packaging deformation caused by high temperature. After cooling, the onions are sent to the packaging line to extend the shelf life and keep the fresh taste.

The production process of frying onions fully reflects the efficiency and refinement of modern food processing. If you are interested in the production equipment in this process, please contact us.
