Frozen French Fries Production Line

The main process of the quick-frozen French fries production line is briefly described as follows:
(1) Presetting of raw materials In order to extend the processing cycle, potato raw materials must be stored for a long time. After long-term storage of raw materials, their sugar content and nutritional components will change to a certain extent. Therefore, a certain period of recovery treatment must be carried out before processing to make the ingredients of raw materials meet the processing requirements.
(2) Desilting cleaning is mainly to remove sediment and foreign matter on the surface of potato raw materials.
(3) Peel and separate the potato skins and spray the color protection solution to prevent oxidative browning on the surface of the peeled potatoes.
(4) Trim The peeled potatoes are manually trimmed to remove the unremoved potato skin, bud eyes, unevenness and green parts.
(5) Cut into strips According to different specifications, cut the potatoes into square strips, and the strips are required to be neat and straight.
(6) Fractional separation of short strips and debris generated during processing to improve yield.
(7) Dehydration and drying adopts a mesh belt drying and dehydration device to remove the surface moisture of french fries and prepare for the next frying process.
(8) French fries are fried in hot oil for a short time, then fished out, and the excess oil is filtered off, so that the unique potato aroma of french fries can be fried.
(9) Quick-frozen fried french fries are pre-cooled and sent to quick-freezing equipment for deep-freezing and quick-freezing, so that the crystallization in the French fries is uniform, which is convenient for long-term freshness-keeping storage and maintaining the original flavor.
(10) Bag-by-bag refrigeration can be carried out manually or by automatic equipment. During the packaging process, the time should be shortened as much as possible to avoid moisture absorption and thawing of quick-frozen french fries, which will affect product quality. Refrigerate immediately after packaging.
