Plantain flour is a powdered food made from green bananas. It is widely used in food processing, nutritional supplements and other industries because of its rich nutrition, unique taste, and easy storage and transportation. How is plantain flour produced? The process of producing plantain flour mainly includes the selection, cleaning, slicing, dehydration, grinding and packaging of plantain. Next, we will introduce in detail how is plantain flour produced.
1. Plantain flour production process
Step ① Material selection and preliminary processing
First, the factory will select high-quality plantain according to the variety and maturity of the plantain. Usually, plantain with low maturity, no pests or damage are selected.
The selected plantain will be sent to the washing equipment for cleaning and disinfection to remove possible pesticide residues and impurities on the surface.
Step ② Peeling and slicing
The cleaned plantain enter the peeling equipment. The peeling process is a very important step in production to ensure that the peeled plantain flesh is clean and intact.
The peeled plantain will be cut into thin slices or small pieces to increase the surface area and facilitate the subsequent dehydration process.
Step ③ Dehydration treatment
Dehydration is one of the most critical steps in the production process of plantain flour. Plantain slice pass through the dryer, which uses hot air to accelerate the evaporation of water, reduce the moisture content, and make the plantain slice dry.
Step ④ Grinding
The dehydrated plantain slice need to be ground into powder by a grinder.
2. Plantain flour production equipment
- Washing machine: used to remove dirt and pesticide residues on the surface of plantain to ensure that the raw materials are clean and hygienic.
- Slicer: can cut plantain into uniform thin slices, which is convenient for subsequent dehydration.
- Dryer: uses hot air to evaporate the moisture in plantain slices, and usually has a temperature control system to avoid excessive temperature from destroying nutrients.
- Grinding machine: grinds the dried plantain slices into fine powder.
- Packaging machine: puts plantain flour into bags according to the set weight, seals and packages.
3. Precautions in the production process of plantain flour
Strict food hygiene management standards should be followed during the production process, and equipment should be cleaned and disinfected regularly to prevent pollution sources from entering the production line.
Quality monitoring and records should be carried out in each link to ensure that the final product meets food safety standards.
