Single-effect evaporation crystallization of a biomass enterprise in Jinan
Food industry evaporation and concentration
1）Prospects
Initially, the steam compressor was only used in the dairy industry in the food industry. After several years of development, the application range has gradually expanded to juice, wine, starch, sugar, additives, fermentation and other industries.
In 1978, the MVR evaporator was used in the dairy industry and gradually replace the traditional TVR evaporator equipment to produce full cream milk powder, skim milk powder, and infant formula.
In 1982, it was used to concentrate products such as tomato ketchup, and it was proved by experiments that the MVR evaporator is much more economical than the conventional evaporator.
In 1985,it is used in the application of candy factories.
In 2001, the MVR evaporator was widely used in the production of whey concentrate, milk concentrate, tomato juice, beet juice, grape juice and starch, and compared with the traditional evaporator, it proved that the energy consumption of the MVR evaporator was reduced by one-third.
2）Some factors need to pay attention when the evaporator is applied in the food industry
For most food materials, the organic matter concentration is higher during the evaporation process, the viscosity is higher at high concentration, and the evaporation condition is higher;
For evaporative food materials, the material selection is higher, and the sanitary grade stainless steel is generally used;
Evaporation of food materials generally requires low temperature evaporation, which can easily cause denaturation or decomposition of heat sensitive materials.

Process introduction |
The single-effect evaporator is used as the intermediate link in the xylose production process. The concentrated liquid from the front end after ion exchange and removal of calcium sulfate enters the evaporation process. Because the organic matter concentration of the material is high and the temperature of the material needs to be controlled below 95 °C, the evaporation process selects single effect. The way of evaporation. Due to the enrichment of organic matter in the later stage of evaporation, the material is more viscous. The centrifuge uses a scraper centrifuge (not recommended to use a two-stage piston centrifuge or a vortex centrifuge), and the treatment effect is good. |
