Calculation of Treatment of Loose Bulky Materials With Ozone-Containing Gas

Abstract

Particularity of treatment of loose bulky materials with gas was analyzed, calculated loss of pressure under their gas treatment. It was ascertained that porosity (pore) of such objects as a layer for seeds of farming crops constitutes approximately 0,4 by capacity. Recommendations were presented on the construction of equipment’s and peculiarity of treatment of layers for seeds and fruit-vegetable products with ozone. KEYWORDS: fruit-vegetable products, ozone-containing gas, loose bulky materials, porosity.

Corona discharge ozonizers with vacuum coatings and their use for processing agricultural products

“…The high voltage was supplied from the high-voltage block via an external high-voltage cable 3 and enters the chamber through sealed high-voltage connectors 2. Voltage up to 25 kilovolts can be supplied through them [11][12][13][14][21][22].…”

“…Noteworthy, air was supplied through pipe 4 from a compressor or fan or oxygen, through a reducer from an oxygen pump. Through the wind tunnel 5, the gas was introduced into the sealed chamber [21][22][23][24]. The wind tunnel 5 was designed for aerodynamic coordination of the air line with the ozonizer chamber (which have significantly different sizes) and provides uniform blowing of highvoltage electrodes, with a smooth increase in the gas flow cross section [17][18][19][20][21][22][23].…”

Through the exhaust pipe, the air-ozone and oxygen-ozone mixture is drawn in by an exhaust fan (not shown in Figure 2) and then through the external exhaust pipe 8 is discharged to a large centrifugal fan of the external exhaust [26][27][28].…”

“…Typically, these devices use cartridges to filter and dehumidify the air. If the cartridge is not changed in time, then the expensive plates of the barrier ozonizer are broken by high voltage and completely fail [21][22][23][24][25]28].…”

“…In a number of cases, it is more expedient to use corona discharge ozonizers for processing such agricultural objects as plant seeds and fruits and vegetables during storage and transportation [17][18][19][20]. This is evidenced by practical studies on the effect of ozone on agricultural products, including electrical ozonation of premises [21][22][23][24][25][26][27][28]. In this regard, it is necessary to conduct comprehensive studies of corona discharges and the possibility of their application for the treatment of plant seeds and other products.…”
