How to Make Carrot Chips in Factor

In the factory, carrot chips processing production line’s main procedures are material selecting→elevator→cleaning→elevator→blanching→cutting→dehydrating→mixing with sugar→pickling→drying→frying→deoiling→packaging.

Carrot chips’ key processing technologies are frying & drying methods, hot air circulation drying is the traditional drying way, with the strengths of high thermal efficiency and low cost, another typical technology is vacuum frying method which could fast dry carrot and keep carrot’s bright color. These two methods will be discussed together with the rest processing steps of carrot chips.

1. Material Strimming

Equipment: knife, plastic basket.
Choose the fresh and mature materials. Cut off carrots’ tops, bottoms and bad spots with a knife.

2. Quality Inspection

Equipment: elevator, working table.
Check the selected materials and return the materials with rotten spots or green tops back to step 1.

3. Brush Type Washing Peeling Machine


Equipment: 2 brush type washer and peeler machines.
Carrots would be washed and peeled by a machine to remove the dirt on its surface. The combined brushing of two machines could clean carrots’ surface thoroughly.

4. Carrot Cutting


Equipment: carrot slicing machine
The carrots could be cut into different shapes and sizes by our slicing machine, and the sizes are adjustable from 0.5mm to 10mm. In this production line, carrot’s thickness is 3mm. With our multifunctional carrot cutter, the factory can produce slices with perfect outlook, avoid injury to hand cutting and enhance efficiency.

5. Blanching Machine

Equipment: blanching machine.
Temperature: 95-100℃
The elevator will send carrots to blanch until the water is boiled. The worker should inspect the blanching machine for at least 30 minutes each time to prevent carrots from being high temperature scalded.

6. Dehydrating

Equipment: carrot chips dehydrating machine
The dehydrating machine adopts the physical centrifugal method to remove the surface water from carrot slices. Four capacity for you to choose: 8-10kg/time, 15-20kg/time, 25-30kg/time and 35-40kg/time.


7. Sugar Mixing and Pickling

Equipment: carrot mixing machine, carrot pickling machine
Pour the dehydrated slices into mixing machine, then add sugar to mix with the carrot. Next, the carrot mixture needs to be pickled for 1-2 hours. The proportion of carrot and sugar is 15:1 or based on market’s and customer’s requirements.

8. Drying

Natural Gas-Coal-Wood-Heating-Full-Automatic-Multi-Layer-Carrot-Drying-Oven

Equipment: hot air circulation drying oven
Working principle: The machine adopts fan to supply continuous air, then, the air will be sent to the heater to get hot wind, next, the hot air will be blown through air channel into the drying chamber. Hot air dryer has open type drying oven and fully enclosed type drying oven. Please note: the closed type hot air dryer has circulation fan when the hot air has been dried and out from the chamber, it will be inhaled into the channel and sent to the heater to get hot air again.
Place the slices evenly on the trays of drying trolley, after that, pull the trolley into the drying chamber. We have tested that, carrot drying at 75℃ with a hot wind speed of 1 m/s can make the preservation rate of carotene increased by 10.86%. Hot air circulation dryer is suitable for evaporating material’s free moisture in the former phase, carrots’ water content will be quickly taken out from material and exhausted outside by the circulating hot air. What’s more, our machine is equipped with automatic temperature control system, when the temperature reaches the set degree gradually, the heater will temporarily stop working and chamber’s temperature will keep at a constant degree, which can produce a product with uniform quality and with no heat loss. Finally, carrot’s water content could be reduced to around 10%.
Next, in order to improve dried vegetable chips’ flavor and crispness. We will use vacuum fryer to deep process carrot chips in the following step. Drying in advance could largely shorten frying time.

9. Frying

Equipment: vacuum frying machine
Working principle: Frying is a dry process of cooking which does not involve water. Vacuum frying happens at below atmospheric pressure, the boiling point of water reduces. Therefore, the required temperature of frying carrot in vacuum dryer is lower than frying at atmospheric pressure, the frying time gets shortened. What’s more, the oxygen content in the vacuum system is relatively low, oxygen’s oxidation effects on carrot chips could be largely weakened, for example, the harmful effects of fatty acid spoilage and enzymatic browning on chips will reduce.
Place the dried carrot chips into vacuum fryer to get fried. The machine’s vacuum degree could be controlled to 0.08MPa; The oil temperature can be set at 80-85℃; The frying time is depended on carrot variety, frying temperature, and the vacuum degree. A specific way is by observing the bubbles on carrots when they all disappear, the vacuum frying ends. Finally, the oil content of carrot chips is about 35%~40%.


11. Packaging

Finally, the incomplete fragments will be rejected, and the qualified products are sorted by weighing and packaged in the vacuum or Nitrogen-filled packing bags.
