In the banana chips processing, removing excess oil is a key link, which not only affects the taste of the product, but also affects the health and quality of the food. Fried banana chips usually have excess oil on the surface after production. If it is not removed in time and effectively, it may cause the banana chips to be too greasy, affecting the consumer experience. So how to remove excess oil from banana chips?
1.Centrifugal deoiling
Principle:
The centrifugal deoiling method uses the high-speed rotation of the centrifugal deoiling machine to subject the banana chips to the centrifugal force during the rotation process. Due to the low density of oil, the oil is thrown off the surface of the banana chips under high-speed rotation. This process is similar to the principle of drying clothes in a washing machine, using centrifugal force to separate liquid from the solid surface.
Operation process:
The fried banana chips enter the centrifugal de-oiling equipment. The machine rotates at a set speed to ensure that the grease can be fully thrown out. After the grease is thrown out, it is discharged through the oil outlet of the machine, and the separated banana chips continue to enter the next cooling and packaging process.
Advantages:
- High efficiency, can remove a lot of grease in a short time, suitable for large-scale production.
- The surface of banana chips is treated evenly, and it is not easy to damage the product structure.
- The grease removal effect is good, and the amount of grease residue on the surface of banana chips is small, which meets the standards of healthy food.
Vibration deoiling method
Principle:
The vibration deoiling method uses a high-frequency vibration device to separate the oil from the surface of the banana chips by mechanical vibration. During vibration, the oil attached to the surface of the banana chips is shaken off and collected through a special oil drainage system.
Operation process:
The fried banana chips are conveyed to the vibration de-oiling equipment. The equipment starts high-frequency vibration, and the frequency is adjusted according to the product type and the amount of oil. During the vibration process, the surface oil gradually separates from the surface of the banana chips through vibration and gravity, and is collected through the oil drainage pipe.
Advantages:
- The equipment has a simple structure and low cost, and is suitable for small and medium-sized processing plants.
- The equipment has relatively low energy consumption and is suitable for energy-sensitive enterprises.
- The processing process has little effect on the physical form of banana chips, and the product damage rate is low.
Both methods have high deoiling efficiency, and the specific method to be selected should be based on actual production conditions.
