syrup

An energy-saving scheme for the production of candied carrots has been developed. The developed scheme includes: washing of raw materials with 1% NaHCO3 solution, reduction of water consumption for blanching, reduction of syrup consumption for saturation of raw materials with sugar. A new drying technology is introduced: candied fruits are dried in a variable temperature mode, namely: in the initial stages with a heat agent at a temperature of 70 0C, at the final stage - with a heat agent at a temperature of 20 0C.

The process of saturation of sucrose particles of pumpkin fruits is considered. An experimental setup for saturation of fruit particles with sugar under conditions of intensive pneumatic mixing was developed. The kinetic dependences of the saturation of candied fruits and changes in the concentration of sugar syrup under various temperatures were obtained. The saturation conditions are compared for various ratios of «candied fruit: syrup». A mathematical generalization confirms the ratio “candied fruit: syrup” selected by the authors of the article.
