The automatic food air dryer mainly uses the wind force of the fan to remove the water on the surface of the food, and it also has the function of cooling. The food cooling machine is suitable for high and low-temperature meat and vegetable products after washing or sterilization. After several turnovers, it bears a good drying effect. Meanwhile, the conveying speed of the mesh belt is adjustable. Due to the high pressure and strong cold wind blowing at the upper part, the air drying efficiency is higher than other drying machines. What’s more, it can match with the sterilization line.
