Development of installations for the production of concentrated pastes made from fruit - vegetable raw materials

Developed a new system for producing concentrated semi-finished products in the form of pastes for the food industry. Currently, an important task of the food industry is the creation of new products with the aim of improving the structure of the range, saving scarce raw materials, as well as reduce sugar intake; development of product functionality and products with extended shelf life. The use of local non-traditional types of plant materials can contribute to solving existing problems. Fruit and vegetable pastes are a valuable food products which can be used as a semifinished product in the confectionery, bakery, food concentrates industry. Fruit and vegetable purees have a distinct structurally viscous or pseudo-plastic properties and concentration form a very viscous mass. Already in the beginning of the process of concentration, i.e. at a relatively low degree of evaporation that leads to a rapid increase in the viscosity of the concentrate mass and reduce evaporation. With increasing temperature is the burning mass, and also change its color and flavor. Therefore, for the concentration of fruit and vegetable purees, you must use equipment whose design takes into account the possible rheological and thermal problems. The analysis of literary data structures evaporators and studies, we developed a system for producing concentrated pastes of fruit and vegetable raw materials. Developed installation can increase the quality of the finished product due to the intensification of the process of concentration, to reduce material and energy resources, increase productivity.
