[0025] Example
[0026] A processing method of dehydrated tomatoes includes the following steps:
[0027] (1) Select tomato raw materials and eliminate defective products in tomatoes: rotten, green and immature tomatoes, straw, metal, hair and other foreign objects;
[0028] (2) Ultrasonic cleaning and peeling: Put the selected tomatoes in saturated salt water containing gravel with a diameter of 1.5 to 2.0 mm, and apply ultrasonic waves to the saturated salt water using a piezoelectric ultrasonic generator. The frequency and sound intensity of the ultrasonic waves are They are 25KHZ~50KHZ and 1.5~3W / cm 2 , The duration is 60 to 150 seconds, then take out the tomatoes and rinse with water;
[0029] (3) Blanching and cooling: blanch the washed and peeled tomatoes with hot water at a temperature of 95~100℃ for 5 minutes, then remove them and place them in cold water to cool;
[0030] (4) Machine cutting: Use a cutting machine to cut the blanched tomatoes into cubes;
