Blanching Pasteurizer Machine

Connected to the processing line via an elevator, the following blanching pasteurizer ensures potatoes are uniformly blanched throughout the production process, effectively removing slime and excess starch after cutting. This improves cooling efficiency and prepares the potatoes for the final preduster coating step. The machine operates with a typical blanching cycle of 4-5 minutes, featuring an adjustable-speed conveyor belt integrated with an air-cooled system. Its upgraded excitation motor functions within a frequency range of 0-125Hz, allowing low-speed operation to prevent overheating during prolonged use. In addition to blanching, this versatile pasteurizer can serve as a sterilization device thanks to its insulated cover, with adjustable belt speeds and pasteurization times ranging from 4 to 60 minutes. A 60-minute timer operates at 3Hz, while a 4-minute timer runs at 90Hz, providing precise control over processing times. Combining blanching and sterilization functions, this multi-purpose equipment is suitable for a wide range of applications—including blanching vegetables, fruits, and seafood to preserve color, nutritional value, and flavor. Beyond processing potatoes, the customer also uses this machine for leafy green blanching and cooling, as well as pasteurizing dairy products, beverages, canned foods, and for braising and cooking poultry, eggs, and meats. This Italian customer employed this blanching machine as pasteurizer machine for pasteurizing packaged snacks. Constructed with a thickened, one-piece stamped body of 304 stainless steel, the machine is sturdy, durable, and capable of handling heavy loads with ease.

Cooling Machine with Refrigerator

Following pasteurization and blanching, the potato strips and cubes are cooled using an air-cooled water cooling system equipped with a 304 stainless steel heat exchanger. The blanching process lasts 4-5 minutes at temperatures between 0°C and -5°C, after which they are rapidly cooled to -5°C by a water chiller. The upgraded motor operates within a frequency range of 0-125Hz, running at low speed to prevent overheating and ensure stable operation. The 5-meter cooling line, featuring a 20HP Bitzer compressor, water cooling, and a 304 plate heat exchanger, is designed with a custom sunken drain outlet, 2mm thick plates, and an extended overflow pipe for easy connection to the sewer system. This setup enables fully automated production of the entire vegetable blanching, washing, and air-cooling process. After blanching, vegetables are briefly heated and then quickly cooled using the refrigeration unit, which helps preserve their color. Similarly, packaged snacks are rapidly cooled after blanching to eliminate microorganisms, significantly extending their shelf life. The subsequent chiller facilitates rapid cooling, supporting air cooling and packaging, and ultimately achieving fully automated, efficient production.

Vibration Screen Machine

Potato strips and cubes exiting the cooling system pass through a vibration screen machine to quickly remove surface moisture. This rapid moisture removal facilitates efficient subsequent air-cooling by eliminating excess water, ensuring the product retains some moisture without being overly wet. This results in more even preduster coating and stronger adhesion when applying powder coatings. The vegetable vibration screen machine is constructed from thickened, multi-layered stainless steel with a one-piece stamped casing.
