Green plantains are the crop with the highest naturally resistant starch content. plantain flour made from green plantains, because of its own characteristics, has the characteristics of high content of resistant starch, gluten-free (gluten), and rich in dietary fiber. It has a good effect on stabilizing blood sugar, helping to lose fat and losing weight, and improving intestinal flora. Resistant starch, as an emerging food material in recent years, has unique advantages in sugar control due to its natural “slow release” characteristics. The excellent performance of plantain powder in sugar control makes it not only edible alone, but also has a wider application in baking and meal replacement. So how to process plantain flour? What processing equipment will be used? Below, we introduce in detail.
1. Plantain Flour Processing Process:
Step 1: Raw material selection
plantains used to make plantain flour are picked and dried before most of their starch is ripened and converted to sugar.
Step 2: Washing
Rinse the plantains with clean water through the bubble washing machine to remove the dust and dirt on the surface of the plantains.
Step 3: Blanching, cooling
Blanch plantains with hot water through a blanching machine, then cool them with cold water for easier and quicker peeling.
Step 4: Peeling
Peel the plantains and remove the silk from the top.
Step 5: Slicing
Put the peeled plantains into the multi-function slicer to complete the slicing process.
Step 6: Color protection
plantains are rich in tannins and enzymes. After peeling and cutting, the flesh is exposed to the air, which can easily oxidize and brown. Therefore, the peeled plantains should be treated with color protection as soon as possible to reduce the color change of plantain slices.
Step 7: Air dry
The color-protected plantain slices are taken out and then passed through an air dryer to dry the moisture on the surface of the plantain slices.
Step 8: Drying
The air-dried plantain slices are conveyed to the dryer through the mesh belt for drying treatment, so that the moisture content is reduced to less than 5%.
Step 9: Grinding
After drying, plantain powder has low water content and strong hygroscopicity. Once exposed to the air, it will quickly return to moisture and agglomerate. Therefore, after drying, it should be ground by a universal pulverizer in time, and ground under dry conditions, but not grind by exposure to air.
Step 10: Packaging
Dried plantain flour should be packaged in time, and the material for packaging plantain flour must have both airtightness and moisture-proof properties, usually aluminum foil composite packaging material, which is sealed and stored.
2. Plantain Flour Processing Machine
According to the above process flow, plantain flour processing equipment mainly includes bubble washing machine, blanching machine, multi-functional slicer, air dryer, mesh belt dryer, universal grinder, etc. In order to improve the level of automation, elevators, conveyors, picking tables, etc. will be added to the equipment room.
