Description

Technical Field

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

[0002] In the industrial production of tomato paste, concentration is a key step, aiming to remove water to increase product concentration and extend shelf life. In the prior art, multiple-effect evaporators, forced circulation vacuum evaporators, or heated concentration tanks are commonly used for tomato paste concentration.

[0003] In practice, a multiple-effect evaporator relies on multi-stage steam concentration. The distribution of the heating tubes and the design of the material flow paths result in significant variations in the residence time and heat intensity of the tomato paste in different areas of the evaporator. This is particularly true in areas directly exposed to high-temperature steam, where the tomato paste is particularly susceptible to localized carbonization due to transient high temperatures. This damages heat-sensitive ingredients like lycopene, affecting the product's color and taste.

[0004] While forced circulation vacuum concentrators enhance material flow through a circulating pump, the high viscosity of tomato paste can lead to turbulent dead zones in pipe bends and heating surface corners, resulting in uneven heat transfer and overheating in some areas. Falling film evaporators are limited by the uniformity of the liquid film distribution. When tomato paste contains fruit particles or impurities, this can lead to uneven film thickness, increasing evaporation rate variations and causing localized overheating or insufficient heating.

[0005] The heated concentration tank evaporates the water in the tomato paste through heat exchange between the medium in the jacket and the tomato paste, thereby increasing the concentration of the tomato paste. However, the tomato paste is heated differently at different positions in the heated concentration tank, which can easily lead to uneven heating during the concentration process, affecting the concentration efficiency.
