How Are Instant Noodles Made in Factory?

Instant noodles, as a quick and convenient food, are loved by consumers of all ages. So how are instant noodles made in factory?
 
In modern instant noodle processing plants, the production of instant noodles typically employs a continuous instant noodle production line process, mainly including the following key steps:
1. Raw Material Preparation and Dough Mixing
The main ingredient of instant noodles is wheat flour, supplemented with water, salt, alkaline water, or food additives. The ingredients are added in precise proportions using an automatic metering system and thoroughly mixed in a dough mixer to create a uniform and elastic dough structure, laying the foundation for subsequent shaping.
2. Rolling and Cutting
The prepared dough is gradually thinned through multiple rolling stages to form a sheet, which is then cut into uniform noodles by a cutting device. This process requires high precision in terms of noodle thickness, length, and consistency, directly affecting the final texture.
3. Steaming and Shaping
The cut raw noodles are placed in a steamer for high-temperature steaming, which gelatinizes the starch and sets the protein in the noodles. This step determines the rehydration speed and texture of the instant noodles when they are steeped or rehydrated.
4. Cutting and Shaping
After being steamed, the noodles are cut and folded or coiled into specific shapes to suit different packaging forms, such as square noodle blocks or round noodle bowls.
5. Frying or Hot Air Drying
Fried instant noodles: The noodle cakes enter a continuous fryer and are rapidly dehydrated at an oil temperature of approximately 150–170℃, forming a porous structure that facilitates rehydration.
Non-fried instant noodles: Dehydrated using hot air drying or vacuum drying methods, which aligns with the trend towards low-fat and healthier options.
6. Cooling, Packaging, and Seasoning
After drying, the noodle cakes need to be fully cooled. They are then packaged together with seasoning powder packets, sauce packets, and vegetable packets using an automatic packaging machine to form the final product.
 

Precautions During Instant Noodle Production:
To ensure the quality and safety of instant noodles, the following aspects require special attention during the production process:
1. Food safety and hygiene control: The production workshop must meet food-grade hygiene standards, equipment must be regularly cleaned and disinfected, and operators must strictly follow hygiene regulations to prevent microbial contamination.
2. Process parameter stability: Parameters such as dough mixing ratio, rolling thickness, cooking time, and frying temperature need to be precisely controlled; otherwise, it can easily lead to the noodles being too hard, brittle, or having an undesirable texture.
3. Oil and energy management: For fried instant noodles, the frying oil needs to be filtered and replaced regularly to prevent oxidation and maintain flavor; energy-saving equipment should also be used to reduce production energy consumption.
4. Product consistency and automation level:
Highly automated production lines help ensure consistent weight, shape, and quality of each package of instant noodles, reducing human error and improving overall production efficiency.
