Seed irradiation is carried out with a cavity resonator by a continuous electromagnetic field at a wavelength of I 12 ± 0.1 cm. The specific power of the high-frequency radiation is 0.80 kW / kg. The sowing qualities of seeds are determined according to GOST.

0 seed n, but there is a decrease in seed germination with respect to the control (Table 3).

In the range of specific power exposure -. The microwave energy 0.3–0.8 kW / kg, the magnitude of reduction in seed germination is almost the same (9–10%), a. With the specific power of the microwave power of 1.1 kW / kg, the magnitude of the reduction in germination increases dramatically (up to 18%). therefore

0 it is advisable to limit the upper range of the specific power of the microwave energy of 0.8 kW / kg. The lower face and a of the specific power of the microwave power of s.ui (has no significant value,

5 however, reducing it to less than 0.3 kW / kg is undesirable, the current as this will increase the processing time and, consequently, limit the performance of the microwave installation during microwave disinsection.

0 An increase in the upper limit of the temperature range of the microwave heating of seeds above 75 ° C) is impractical, since this leads to an additional decrease in the hc similarity of seeds.

5 In table. 6 shows the data for microwave reset with such modes.

In order to preserve the similarity of the seeds after the CP.Ch-de-schenskii predalggags the technological operation of intensive oh-donipipe seeds flow with

cooling rate greater than or equal to the speed of the SBS-nagreps. This condition is satisfied if the cooling of the seed wire in a suspended (pseudo-oxy;:;; gnn) state. It was established experimentally that the seeds of legumes are in suspension at a flow rate of 5-7 m / s and a specific air flow rate of 0.1-0.2 m3 / s per 1 kg of seed.

A decrease in the lower limit of the cooling parameters leads to a violation of the suspension of seeds in air flow and to a deterioration in the uniformity of cooling of the entire seed mass. Increasing the upper limit of the cooling parameters also disrupts the weighting of the seeds in the air flow, and there is a danger of damage to the seed wall of the working chamber.

The maximum upper temperatures of the seeds after cooling to 30-35 ° C are determined by the fact that at these temperatures, even with prolonged exposure, there is no significant effect on seed germination. Limit reduction

seed temperature after cooling within positive temperatures also has no significant effect on seed germination,

In tab. 7 shows the modes of microwave processing and the main results of the disinsection of pea seeds from the pea weevil by the proposed method, i.e. the microwave heating followed by cooling to a temperature of 35 ± 1 ° C 19 ± ° C.
