Procedure and equipment for anaerobic seed dressing

The subject matter of the invention relates to a method and facility for anaerobic seed dressing, especially of barley and wheat kernels, against smut fungus (Ustilagojc

The pathogenic organisms of the fungal disease which are found within the seeds are very difficult to destroy, since at the same time as they are destroyed, the biological vertebrae of the seeds could perish or be damaged. So up to the present day physical methods have proven to be better than chemical ones, and thermal pickling is one of them. In the thermal process, the seed is either prewetted first for a period of 4 hours and at a temperature of 28-30 ° C and then dressed in warm .Vasser at 50 ⁰ C for 7-10 minutes, or it is single-phase in the water of Pickled 47 ⁰ C for 2 hours.

Since the seeds come into contact with water for 2-4 hours comes, the seed takes on great moisture during dressing and must then be dried for a long time. Also is

this method is very sensitive to stalling a very narrowly limited heating temperature. With a lower Tetipe temperature than necessary, the effect is insufficient; if the desired temperature is exceeded, the oil is damaged.

However, some methods of anaerobic seed dressing are more advantageous against iJrand fungus disease (tstilago). Before the anaerobic Dressing the seed is initially wet with. »Water to to raise their moisture content. The moistened seed is then placed in a closed room without admission of air pickled at a certain temperature for a certain period of time. In our own research it became clear that with anaerobic Dressing a regular dependence between seed moisture with the pickling process, pickling temperature and the period of time required for complete pickling, «Earlier Anaerobic pickling methods used long-term wetting similar to the thermal pickling method, A disadvantage of this process is a high absorption of Moisture from the heat and cumbersome drying. The seeds cannot be sown after dressing without drying will.

The invention is based on the object of a new method and a new device for anaerobic dressing of the seeds of barley and wheat based on a quick and effective uptake of wet by the seed under negative pressure, a short-term wetting of this seed and a quick changeover of its temperature to the dressing temperature by the

The process-related solution of anaerobic heating according to the invention is based on the fact that the oamen are introduced into a ui'ucku.ef äß the heating pad, whereupon negative pressure is set in the vessel and through the action of the liter pressure the aainen evenly suck up the .wetting liquid and become then warmed to the heating temperature.

To manage suction or pressure side «The unit enables the filling and emptying of the vessel 1 with water by means of the pipeline 6 from the iNiässungslösungigkeitsgefäß 7 in total in a fraction of the time required for the actual heating. This is of great importance, as the whole seed is brought to the same moisture level at once and at the same time same temperature is heated, creating conditions be created for good effectiveness in the total amount of seed. To withdraw the products of the anaerobic process is below the vessel 1, a fermentation closure 9 with a valve 10 and a Huslaßstutzen 11 for emptying the dressed seed is appropriate.

The device works as follows:

The seed is filled into the vessel by means of the nozzle. That The vessel is then hermetically sealed. By means of a compressor, negative pressure is formed in the vessel in such a way that through the tap setting 5 the Kohrleitung 3 is under suction of the compressor. By opening the valve 8 on the rtasserrohleitung 6 fills the vessel quickly with water of the desired temperature from the wetting liquid container 7, the tap 5 is closed. When the filling is complete, the valve 8 is closed and the seed continues to grow exposed to the action of water. Then the compressor 4 is set in motion and by means of the sewing 5, the pipeline 3 is connected to the pressure side of the compressor 4, and the valve s open. Even before the complete development

emptying the water from the vessel 1, the tap 5 is closed, so that the air from the compressor 4 does not flow through the moist seed and thereby change the seed temperature. The residual overpressure removes the raucous water that still remains and immediately afterwards the valve 8 is closed. The vessel is thereby closed and the rtasser that is served by the If the surface of the seed trickles down and would collect at the bottom of the vessel 1, it gradually flows through the fermentation seal 9 after opening the valve IO from the vessel. This valve remains until this time, i.e. during the filling, wetting and emptying closed. The fermentation seal 10 closes an air inlet into the vessel the end. A thermometer is used to determine the internal temperature of the container observed, but thermometers can also be used, which are attached to different * places. iAfter completion During the actual process, the dressed seed is removed from the vessel through the outlet nozzle 11.

To increase the performance of the pickling device, it is possible to put the pressure vessel 1 and several auxiliary pickling tanks in batteries compiled to use. The moistened and tempered seed from the pressure vessel is diverted into these vessels to expose them to the pickling process. Auxiliary pickling vessels do not have to be set up for pressure, it is completely sufficient if they can be hermetically sealed and with are provided with a fermentation lock.

The seeds which are dressed in accordance with this invention can

be sown directly in the event that the pickling in the time before Sowing is carried out because the seed is a proportionately has low humidity.

The pickling process of this invention was carried out with a major one The amount of grain has been tested in practical trials and its advantages over other methods have been fully confirmed. The seed that was pickled in this way was perfect fire fungus free. i ^ in perfect effectiveness of the pickling process is very important because with the previously known λίβ-methods, did not guarantee full effectiveness, it could lead to the formation of new ßrandpilzrassen, which differ are resistant to other imperfect pickling processes. The pickling process according to the ί invention gives a Complete prerequisite, the Brandi disease completely out of the v.elt to create. This fact presents another benefit compared to other pickling processes. tmrch the results Practical tests have confirmed that a seed which has been dressed in this way will remain free of disease for years to come and further pickling was no longer necessary.
