The potato blanching machine is designed for rinsing potato chips or fries on French fries production lines and potato chips production lines. By treating the potatoes with hot water or steam at high temperatures, the internal enzymes are inactivated and the surface is softened, thus preparing them for subsequent processes such as cutting, frying or freezing. In addition, blanching kills certain bacteria and ensures the safety of vegetables and fruits. LONKIA offers a wide range of vegetable blanching machine models and can design and develop vegetable and fruit blanching machines according to customer needs and requirements for processing lines of different sizes.

Working Principle of Potato Blanching Machine
The core function of the potato blanching machine is to heat treat potatoes after slicing or cutting to improve their color, texture and processing stability. The potato blancher creates a high-temperature hot water environment by heating water in a tank to a set temperature (generally between 80°C and 100°C), providing the necessary conditions for potato blanching.
During processing, the potatoes are fed into the hot water for a short period of time. Due to the low density of potato chips, easy to float on the water surface, for which the vegetable blanching machine is equipped with a special pressure mechanism, which can gently press the floating potato slices into the water, to ensure that the hot water can be fully contacted with each piece of material, so as to achieve a more uniform bleaching effect. The general bleaching time is controlled between 1 and 2 minutes, and the time can be adjusted according to the actual process requirements.
In the blanching process precipitation of starch will be deposited at the bottom of the equipment, the potato blanching machine is designed with a starch centralized collection function, easy to follow up the use or processing, improve resource utilization.
Types of Industrial Blanching Machine
There are usually two types of blanching machine. One is continuous potato blanching machine. The machine can be operated continuously, the material is continuously rinsed on the conveyor belt through the hot water tank, the rinsing is even, high efficiency, suitable for large-scale vegetable and fruit processing production line. The second type is spiral blanching machine. Spiral blanching machine is equipped with a spiral propulsion structure inside, the material travels along the spiral path in the hot water, suitable for rinsing all kinds of vegetables, seafood and so on. You can tell us the materials you need to bleach, we will recommend the most suitable bleaching equipment for you.
