Making fried onions is a systematic and highly automated process. So how to make fried onions?
The main production process includes: peeling → slicing → washing → coating → frying → degreasing → cooling → packaging.
1. Peeling
Equipment: Onion peeling machine
Note:
Choose fresh onion raw materials without disease spots.
The onion size should be relatively uniform to facilitate automated processing.
Be careful to remove onions that are moldy, rotten or severely mechanically damaged.
2. Slicing
Equipment: Onion slicer
Note:
The slice thickness is usually controlled between 1.5~2.5mm. If it is too thick, it will not be easy to fry through, and if it is too thin, it will be easy to burn.
3. Cleaning
Equipment: Bubble Cleaner
Notes:
Wash with clean water for 2~3 minutes, and keep the water temperature at room temperature.
It is recommended to drain after cleaning to reduce the water burden entering the breading machine or frying machine.
4. Coating
Equipment: Coating machine
Common coating materials: corn flour, wheat flour, seasoning mixture, etc.
Notes:
The coating should be even and thin to avoid the heavy coating affecting the taste.
The powder should be dry to prevent clumping.
Seasoning powders such as chili powder, salt, and pepper can be added according to customer needs.
5. Frying
Equipment: Continuous fryer
Note:
The oil temperature must be stable. If the temperature is too high, it will burn easily. If the temperature is too low, it will absorb too much oil.
Use edible oil with high stability (such as palm oil) and avoid frequent replacement.
When frying, it should be conveyed continuously to avoid overlapping and accumulation to ensure uniform frying.
Remove oil residue in time to extend the service life of the oil and keep the fried food golden in color.
6. De-oiling
Equipment: Centrifugal de-oiling machine or vibration de-oiling machine
Notes:
The de-oiling time should be controlled within 20-30 seconds to prevent excessive dehydration from affecting the taste.
De-oiling helps to extend the shelf life, improve the crispness and reduce oil consumption.
Through the reasonable control and coordination of the above steps, as well as the use of fried onions machines, a fried onion product with a crispy outside and tender inside and golden color can be produced.
