Improving the technology of obtaining powders from plant raw materials
The demand for powders from plant materials is currently increasing, since all biologically active substances contained in the original fruit, vegetable or berry are maximally preserved in them. Food products created with their addition have a functional purpose, which helps to improve the population and maintain immunity, and are also useful as a prophylaxis for many diseases. The quality of the resulting product is largely determined by the size of the grinding. At the same time, the process of obtaining plant powders of a given degree of grinding is complex in theoretical and applied aspects. The aim of the work was to consider the technology of grinding plant materials into powder with specified sizes of the resulting particles. To increase the efficiency of the process for producing powders, it is proposed to use a two-stage grinding vacuum installation, which includes a disk grinder, a container, a ball mill, and a vacuum particle removal system. Theoretically, followed by experimental justification, the number of knives of the disk chopper of the first stage. A formula is proposed that allows one to analyze the efficiency of grinding plant materials in various plants. A linear law is established for reducing the mass of waste particles from increasing grinding time. For the proposed design of a ball-cylinder conical mill, which is the basis of the installation, a formula is given that specifies the frequency of its rotation.
