A unique membrane unit was launched in the experimental workshop of the Educational and Experimental Plant of the VGMHA named after V.I. Vereshchagin. It was developed by a Vologda manufacturer of technological equipment for the food industry according to the technical design of Vladimir Shevchuk, Associate Professor of the Department of Technological Equipment.
Membrane processes are widely used in the dairy industry. They are used to concentrate liquid dairy products and separate them into fractions.
The new installation is universal and allows for ultrafiltration, nanofiltration and reverse osmosis processes. The cascade of high-pressure pumps creates the necessary pressure, under the action of which the separation of the components of the dairy raw materials occurs on the rolled polymer membranes. Automation, membranes and other components are predominantly domestic production.
Today, Russian enterprises use foreign installations, but, as a rule, they are very expensive to purchase and maintain, they have very high productivity, which is not always needed, the press service of the Vologda GMHA reports.
“There are practically no such installations on the Russian market. It partially consists of imported components, but thanks to its creation, we have ideas for its modernization, improvement, and a complete transition to the domestic component base, – said Vladimir Shevchuk, – We want to carry out some hydrodynamic calculations in order to improve the flows in this installation , we plan to slightly change its scheme, abandon some components, and thus reduce its cost so that it is as reliable and easy to operate as possible.”
In the Vologda State Medical Academy, in particular, the membrane unit is used to produce lactose-free and low-lactose milk, as well as food lactose. Recall that at the end of 2021, a research team led by Associate Professor of the Department of Technological Equipment Vladimir Shokhalov won a state scientific grant of the Vologda Region in the amount of 2,100,000 rubles. The money was allocated for the implementation of “Development of technology for lactose-free milk and food lactose based on scientific research on membrane and enzymatic processes for processing dairy raw materials.”
