Description

 The invention relates to the field of storage of agricultural products, and in particular to methods of processing root crops of sugar beets before processing.

 The invention is new and has no analogues.

 The method is illustrated in the drawing, which shows a block diagram of the installation used.

 The proposed method is as follows. Beets are laid in kagaty. A permanent magnet 1 and an emitter 2 of an electromagnetic field are installed near it so that the maximum number of lines of magnetic induction of the electromagnetic field penetrates the volume of sugar beet laid in the kagat. During storage of sugar beet, it is exposed to a constant magnetic field, the magnetic induction of which is 0.1 mT, and an amplitude-modulated electromagnetic field with a carrier frequency of 1 kHz and a frequency of modulating oscillations lying in the extremely low frequency range of 3 - 30 Hz for 50 minutes.

 When the unit is turned on, sinusoidal oscillations of the extremely low-frequency range from the output of the generator 3 are fed to the input of the frequency meter 4 and to the input of the generator 5, which generates oscillations of the carrier frequency of 1 kHz and simultaneously produces amplitude modulation of the electrical oscillations. From the output of the generator 5, the oscillations go to the input of the amplifier 6 and from the output of the amplifier, the electric waves go to the oscilloscope 7 to control the waveform and are simultaneously fed to the emitter 2, which is a multilayer coil. As a result, an electromagnetic field is created that acts on root crops.

 During storage of sugar beet root crops, biochemical processes occur in them, leading to the loss of sucrose. These processes are caused by the respiration of sugar beets and the conversion of sucrose into some non-sugars. As is known, the interaction of an electromagnetic field with atoms having paramagnetic properties has a resonant character, and there is a change in the spin orientation of electrons at the last energy levels. As a result of this, the speeds of some reactions slow down, while others accelerate (Kuznetsov AN, Vanag VK. The mechanism of action of magnetic fields on biological systems. Biological series N 6, 1987. S. 814-825).

 Reactions associated with the decomposition of sucrose are slowed down; therefore, the content of sucrose in root cells remains unchanged for a long time. In root crops that were not exposed to an electromagnetic field with the above parameters during storage, the sucrose content in the cells decreased due to normal biochemical processes.

 Exposure to a constant magnetic field, the magnetic induction of which is 0.1 mT, must be performed on the roots of sugar beets when the storage temperature drops to negative values on the Celsius scale.

 Such treatment with an electromagnetic field with the indicated parameters should be carried out every month during the storage period.

 Example.

 One ton of sugar beet, in which the sucrose content averages 17.4%, is placed in the kagat. A permanent magnet 1 and an electromagnetic field emitter 2 are installed near it so that the electromagnetic field penetrates the entire volume of the kagat. Once a month with a shelf life of four months, root crops are exposed for 50 minutes to an amplitude-modulated electromagnetic field with a carrier frequency of 1 kHz and a frequency of modulating oscillations of 18 Hz, while the magnetic induction of the amplitude-modulated electromagnetic field is 0.3 mT. The modulation depth of the amplitude-modulated electromagnetic field is 70%. The inductance of the emitter is L = 0.3 GN. In parallel, from the beets of the same batch lay the kagat and store under the same conditions as the processed one. Before transporting sugar beets to the plant, the sucrose content is determined. As a result, the sugar content in the treated root crops is 17.1%, and in the root crops of the control crop 16.1%. Thus, the loss of sugar in processed root crops is less.

 Using the proposed method can significantly increase the profitability of production, since with minimal energy costs there is a significant increase in sugar yield during processing.
