Description

The device relates to microwave processing and can be used in agriculture for the processing of bulk materials, such as seeds of crops before sowing.

A device for microwave processing of seeds is known, which comprises a volume resonator mounted by a dispenser, most of which is connected through the waveguide to the output of a source of electromagnetic microwave energy, moreover, the volume resonator is rectangular and equipped with a hollow dielectric insert in contact with the inner walls, on which alternating longitudinal the axis of the volume resonator pitched trays directed towards each other and having a brochistochron profile, while the lines of symmetry of these trays and lines The symmetries of the waveguide are located in the same plane, and the inlet and outlet openings of the volume resonator are equipped with transverse waveguides (AS USSR No. 1787346, А01С 1/00, 1993, prototype).

The disadvantage of this device is the uneven heating of the processed material and the impossibility of rapid cooling, as this greatly affects the quality of processing.

The objective is to develop a device with the possibility of more uniform heating of the processed material with simultaneous cooling, for example, seeds of crops before sowing.

The technical result is achieved due to the fact that, in contrast to the prototype, the device contains a microwave source, waveguide, hopper, moreover, it is equipped with an obliquely mounted rotating screw pipe, the inner surface of which is made in the form of a spiral of dielectric material and mated through a bearing assembly at the base of the working chambers with a cooler pipe made of a grill. The auger pipe and the cooler pipe are equipped with a gearbox with an engine to drive them into rotational motion.

Figure 1 presents a General view of the device for presowing treatment of seeds. Figure 2 presents a longitudinal section of a pipe-auger.

The device for presowing seed treatment contains a source 1 (Fig. 1) of an ultrahigh frequency connected to the working chamber 2 through a pyramidal horn 3 and a waveguide 4. In the working chamber 2, a rotating screw 5 tube is inclined, the inner surface of which is made in the form of a spiral 7 ( figure 2) from a dielectric material 6, for example fluoroplastic, in which seeds of crops undergo pre-sowing treatment in the field of ultra-high frequency (microwave).

The screw pipe 5 is interfaced through the bearing assembly 11 in the base 12 of the working chamber 2 with a cooling pipe 8 made of a metal grill and located outside the working chamber.

The screw pipe 5 connected to the cooling pipe 8 is rotationally driven by a reducer 9 with an engine 10.

The device is equipped with a loading hopper 13 mounted on the bed 14. The loading hopper 13 is equipped with an engine 15 for driving a conveyor belt 16.

The cooler pipe 8 is connected to a discharge hopper 17, which is equipped with a fan 18 with an engine 19 and a discharge hatch 20.

An absorber 23 is installed on the rear wall of the working chamber 2 to compensate for microwave energy.

Management of the equipment is carried out at the expense of the distribution cabinet 21 and the control panel 22.

A device for presowing seed treatment works as follows.

Pre-moistened bulk material, for example seeds of grain crops, from the hopper 13 with the help of a conveyor belt 16 enters the screw pipe 5, which is located in the working chamber 2. Due to the inclination and rotation of the screw pipe 5, the seeds are moved through its entire length, processed in the microwave field and are heated to the required temperature. Next, the seeds of agricultural crops, for example, grain crops, enter the cooler pipe 8, located outside the working chamber 2 and made of a metal grill 8, cooled by the outside air, which is sucked in by the fan 18 with the engine 19 through the cyclone 17. Due to the air flow, tilt and rotation the screw pipe 5 and the cooler pipe 8 the processed material enters the discharge hopper 17. The speed of passage of the material through the working chamber 2 is controlled by the speed of rotation of the engines 10 and 15.

This device can be easily implemented in agricultural engineering and is used, for example, for pre-sowing microwave treatment of seeds of various crops.
