French fries are a kind of food made from potatoes, cut into strips and deep-fried. It is one of the common fast foods and is popular all over the world. Many of you know that French fries are Potato Chips in English, and Americans call them French Fries. Do you know how French fries are made? Here will show you frozen french fries manufacturing process.
The industrial batch production process of French quick-frozen fries is as follows:
- Drum preliminary screening: In order to remove mud, small rocks and other debris in the field, the newly unearthed potatoes have to go through a preliminary drum screening before being sent to the processing plant.
- Potato size selection: The washed potatoes go through a vibrating grid conveyor belt, and the small ones are shaken onto the conveyor belt below. The potatoes with different sizes are divided into two conveyor belts.
-
Washing and peeling: potatoes are cleaned and peeled by a potato washing and peeling machine.
-
Manual screening: Manual screening of rotten bad potatoes and potatoes that have not been completely peeled.
- Cutting French fries: The peeled potatoes enter the slicer and are cut into small grids of French fries, then fall into the water-containing assembly line and transport to the rinsing line.
-
Rinsing: The cut fries enter the high-pressure bubble cleaning machine to rinse the mucus on the surface. Before fries, the fries should be soaked in water for a while to remove the starch, so that they will not be oxidized and discolored by the air
- Blanching: The cleaned French fries are blanched in the blanching machine to inactivate the oxidase in the fries, prevent color deterioration and accelerate dehydration.
- Water cooling at room temperature: Transport the blanched French fries to a conventional washing machine for cooling at room temperature.
- Vibration draining: After pre-cooling, the French fries enter the vibrating drainer to remove excess water.
- Frying: Put French fries into soybean oil at 187 degrees Celsius for pre-frying
- De-oiling: The French fries that have just come out of the pan still carry oil, and the oil on the French fries is drained through a special conveyor belt with holes.
- Quick-freezing: After pre-cooling, the quick-freezing is carried out by a quick-freezing machine. The quick-freezing temperature is controlled below -36 degrees to ensure that the core temperature of the potato product drops to below -18 degrees within 18 minutes.
- Packaging: Control the weight scale of the weighing pan, and automatically enter the packaging funnel every time 4 kg of frozen French fries are dropped. The quick-frozen potato products should be quickly bagged and boxed.
-
Refrigeration: bagging. The products after packing are stored in the cold storage at -18°C.
