Banana Chips Making Process in Factory: From Raw Bananas to Crispy Snacks

Banana chips are one of the most popular fruit-based snacks in many countries. They are crispy, flavorful, and shelf-stable, making them ideal for both domestic and export markets. In modern food factories, banana chips are produced through a standardized and efficient process to ensure consistent quality, taste, and texture. Below is an overview of the complete banana chips production process in a factory.

1. Raw Material SelectionThe quality of banana chips starts with fresh bananas. Factories typically use unripe, firm bananas because they maintain shape during slicing and frying. Bananas are sourced from farms, inspected, and sorted to remove damaged or overripe fruits.Key requirements:Firm textureUniform sizeNo bruises or rot
2. Washing and PeelingOnce delivered to the processing line, bananas are thoroughly washed to remove soil and impurities. Peeling can be done manually or with semi-automatic peelers depending on production scale.Purpose:Ensure clean, uncontaminated fruit before slicing.
3. SlicingPeeled bananas are fed into a banana slicing machine, which cuts them into uniform slices. Slice thickness is adjustable depending on product requirements.Common slicing types:Round slicesOblong slicesRipple / wavy slicesUniform slicing ensures even frying and consistent crispiness.
4. Blanching or SoakingBefore frying, many factories use:Hot water blanching, orSoaking in salt/turmeric solutionThis step prevents enzymatic browning, enhances color, and improves the chips’ final texture.Benefits:Natural color retentionReduced oil absorptionImproved flavor
5. De-wateringAfter soaking or blanching, excess surface water is removed using:A de-watering machine, orA spin dryerThis step helps reduce oil splashing and promotes uniform frying.
6. FryingFrying is the most important step in making chips crispy. Industrial factories use:Two common frying systemsBatch fryer – suitable for small to medium productionContinuous fryer – used in large-scale factories for automatic feeding, frying, and dischargeFrying features:Temperature typically 160–180°COil circulation system ensures consistent heatAutomatic time and temperature control for uniform crispiness
7. Oil DrainingFreshly fried chips are transferred to an oil-drain conveyor or vibrating deoiling machine to remove excess oil. Proper deoiling enhances taste and extends shelf life.
8. SeasoningOnce deoiled, the chips move to a seasoning drum, where various flavors are added, such as:SaltedSweetSpicyCheeseBarbecueHoneySeasoning is evenly applied as the drum rotates.
9. CoolingBefore packaging, chips must be cooled to room temperature to avoid moisture buildup inside the bag, which could reduce crispiness.Cooling is typically done on a cooling conveyor.
10. PackagingThe final stage is automatic packaging, using pillow-bag or vertical form-fill-seal (VFFS) packing machines.Packaging goals:Maintain freshnessProtect from moistureExtend shelf lifeCommon materials include laminated plastic and nitrogen-flushed packs to keep the chips crisp.

Main Equipment Used in Banana Chips ProductionA typical banana chips factory uses the following machinery:Banana washing machinePeeling equipmentBanana slicerBlanching machine / soaking tankDe-watering machineBatch fryer or continuous fryerOil draining machineSeasoning drumCooling conveyorPackaging machineThe level of automation can be customized based on factory size.

The banana chips making process in a factory is a well-organized flow that includes washing, peeling, slicing, frying, seasoning, and packaging. With the right equipment and process control, manufacturers can produce high-quality banana chips with excellent taste and long shelf life. This standardized production helps factories meet demand from supermarkets, wholesalers, and export markets around the world.
