The processing flow of Dehydrated Tomato Powder is: tomato → washing → picking → crushing → beating → vacuum concentration → sterilization canning
(1) Selection of raw materials
Use fresh, ripe, bright red tomatoes.
(2) Cleaning
Remove sediment, residual pesticides and microorganisms adhering to the fruit.
(3) Select
Remove rotten, diseased, or poorly colored tomatoes.
(4) Thermal crushing
The crushing methods of tomatoes include hot crushing and cold crushing. Thermal pulverization refers to a treatment method in which Dehydrated Tomato is heated to 85°C immediately after pulverization. Since the thermal pulverization method can passivate the pectinesterase and polygalacturonase in the tomato pulp in time, a large amount of pectin substances are retained, and the final tomato product has a high consistency.
(5) beating
The purpose of beating is to remove the skin and seeds from the tomatoes. Double or triple dozen are used for beating. The aperture of the screen of the first beater is 0.8-1.0 cm, and the aperture of the screen of the second beater is generally 0.4-0.6 cm. The speed of the beater is generally 800 to 1200 rpm. The amount of skin residue obtained after beating should generally be controlled at 4% to 5%.
(6) vacuum concentration concentration
The methods include vacuum concentration and atmospheric concentration. Due to the high concentration temperature of atmospheric concentration, the color and flavor of tomato pulp will be reduced when heated, and the product quality will be poor; while the temperature used in vacuum concentration is about 50 °C, and the vacuum degree is above 670 mmHg.
(7) Dehydrated Tomato Granules Dried Tomato Concentrate

There are many drying methods, mainly freeze drying, puff drying, drum drying, foam layer drying and spray drying.
