How are canned tomatoes made?The following are the basic tin canned tomato processing steps to produce high-quality peeled/diced tomatoes:

• Suitable tomatoes are transported to the manual sorting table by flotation;

• Cleaning and manual sorting on the roller belt by personnel;

• Peeling;

• The whole peeled tomatoes are sorted manually on the inspection belt by personnel

• Use a continuous dicing machine to dice the whole peeled tomatoes;

• Drain the diced tomatoes through a vibrating screen device (de-juice);

• Manual or automatic sorting of dice;

• Use screw-type shredder pumps to recover the waste generated by optical and manual sorting, debarkers and debarkers and transport them to the heat exchanger;

• Heat all recycled waste to 90°C in the tube heat exchanger;

• Use a pulper to refine hot waste;

• Concentrate the juice to 8 / 11°Brix;

• According to the customer's instructions, mix the diced tomatoes with the semi-concentrated juice.

To achieve the automation and intelligence level of the canned tomato production line, the relevant canned tomato processing equipment is indispensable. At the same time, related equipment on the tomato canning production line has also benefited from the market. The raw material hoist, washing line, peeling machine, filling machine, can sealing machine, sterilization machine, etc. are all indispensable parts of the assembly line. Improve the level of automated production and reduce the participation of labor. While improving production efficiency, it can also avoid the pollution caused by labor. Tomato washing machine: The tomato washing machine uses the impact force of high-pressure water to push the tomatoes forward, which is hygienic and reliable. It can not only play a cleaning role, but also save electricity.

Tomato washing machine:

Driven by the water in the conveying tank, the tomatoes follow the water flow into the next process. Equipped with spray cleaning device. The ingenious double-layer design allows sand and gravel to settle to the bottom and be discharged.

Tomato peeling machine:

Tomato peeling machine use hot water to remove the skin of tomatoes, and then remove them with a rubber roller (if higher quality products are required, they can be removed by hand).

From here, use positive displacement bulldozers to fill cans and cans. They are weighed (before adding the liquid), sealed, and then sterilized using an autoclave or continuous pasteurizer according to the pH of the liquid.

Manual selection: After peeling, the tomatoes undergo another manual selection, in which the collaborator cannot detect the defects through technology. After that, the selected ones are sent to the packaging line

Tomato filling machine:

Tomatoes are put into the tank through volumetric cans, and the empty container is put into the tank and filled up according to the gram weight of the tank. The cans are manufactured in our metal container factory located in the same factory.

Two-stage sterilization:

the filled cans are placed in a large pasteurization machine under atmospheric pressure, which is equipped with a can rotation device. These machines heat the product to 98°C within a preset time, which varies according to the size of the tank. The core must reach at least 95°C to ensure perfect product pasteurization. In this type of process, a canned rotary pasteurizer must be used, otherwise the heating time will be too long, which will reduce the quality of the finished product.

Finally, the containers are placed in an automatic palletizer for labeling, and bulk goods are prepared and sent to the market.
