Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of drying devices, and in particular, to a drying device for tomato sauce production. Background Art

[0002] Tomato sauce is a concentrated sauce product made from ripe red tomatoes that are crushed, pulped, concentrated, canned, and sterilized. It is bright red or dark red in color, tastes sweet and sour, and is rich in nutrients. It not only increases appetite but also helps digestion. In addition to lycopene, tomato sauce also contains B vitamins, dietary fiber, minerals, protein, and natural pectin. Compared with fresh tomatoes, the nutrients in tomato sauce are more easily absorbed by the human body. The process of making tomato sauce is not complicated. First, select fresh, ripe tomatoes, wash them, crush them, and pulp them. Then, through heating and concentration, some of the water in the tomato pulp is evaporated to form a thick sauce. Finally, it is canned and sterilized to ensure the hygiene and safety of the tomato sauce.
