In order to ensure the taste, appearance, shelf life and production efficiency of french fries, the production process of french fries must rely on a series of key technologies. what is the production technology of frozen french fries? The following is an introduction to several technologies commonly used in the production process of french fries.
1. Potato cleaning and peeling technology
The quality of french fries begins with the processing of raw materials. First, fresh potatoes must be cleaned and peeled.
Cleaning technology: A drum cleaning machine is usually used to remove dirt and impurities on the surface of the potatoes through water washing and drum friction.
Peeling technology: Mainstream equipment includes steam peelers and mechanical peelers. Steam peelers use high-temperature steam to quickly soften the skin, and then peel it off through a friction device. This method has low loss and high efficiency, and is a common method used in modern factories.
2. Cutting technology
Cutting potatoes into uniform strips is a key step in french fry processing. The potato strip cutter can adjust the cutting thickness to ensure that each french fry is of the same size, which is conducive to subsequent frying and quick freezing.
3.Blanching technology
The potatoes need to be blanched after being cut into strips. The main purpose is to gelatinize the starch on the surface of the potatoes, prevent oxidation and discoloration, and improve the taste. Blanching is usually carried out in hot water at 85℃~95℃ for 30 seconds to 1 minute.
4. Frying technology
The deep fryer fries the french fries in oil at 170℃-180℃ for 30-60 seconds, forming a thin crispy crust on the surface while keeping the inside raw.
5. Quick freezing technology
Use a quick freezer to quickly freeze the french fries at -35℃~-40℃ to ensure that the ice crystals are small and uniform, and the structure and taste of the french fries are preserved to the greatest extent. Quick freezing technology is essential to extend the shelf life of the product and facilitate transportation and storage.
As the consumer market’s requirements for food quality continue to increase, french fry production technology is also continuously upgrading. Automation, digitalization and intelligent control are gradually becoming the mainstream trend of modern french fry processing factories.
