OVU-25U Stationary Reinforced

Stationary Grain Cleaning Machine

The stationary reinforced OVU-25U is a grain cleaning machine in the form of a basic cleaning module, from which everything superfluous has been removed, retaining only the key elements of the OVS-25, such as the air and sieve cleaning unit. This design lacks the self-propelled mechanism, chassis, loading, and unloading units of a classic OVS-25, which makes its application entirely justified for modernizing existing grain cleaning complexes (ZAV). Unlike the outdated and inefficient cleaning methods traditionally used in typical ZAV-20, ZAV-40, ZAV-100, and others, this grain cleaning machine will significantly improve cleaning efficiency and also become a cost-effective replacement for obsolete equipment. The high performance of its work is achieved thanks to a series of well-thought-out engineering solutions, among which the following should be highlighted:

• Use of reliable bearing assemblies
• Increased metal thickness in the most loaded zones
• Design of sieve mill connecting rods with a significantly longer service life
• Improved self-cleaning system for the sieves (32 brushes)
• Possibility of individual retrofitting of the machine for specific conditions

More about the stationary grain cleaning machine for ZAV

The basis of the stationary OVU-25U model is the classic and time-tested two-level OVS cleaning system, which effectively combines air and sieve separation and is used in most grain cleaning machines. At the first stage, the unprocessed grain mass fed into the receiving chamber passes through a powerful air stream - the aspiration system separates dust, chaff, light impurities, and trash. After this, the pre-cleaned material enters a block of parallel-operating sieve mills. This unit experiences maximum dynamic loads and is traditionally considered a weak link in machines of this type, so the engineers at Zavod Moroza paid special attention to this element, turning it into a key advantage. We have implemented a modified connecting rod design and increased the overall strength of the unit by using thick metal, which has significantly extended the service life and reliability of this mechanism. Furthermore, to prevent the clogging of openings, especially when working with wet or heavily contaminated grain, the number of brushes for cleaning the sieves was increased to 32 units, which ensures an effective self-cleaning of the system. Thus, these improvements significantly enhance the operation of the grain cleaning machine and fulfill the main goal of ZAV modernization - stable productivity, reliable and uninterrupted operation, and overall high quality of the final product.

Since this grain cleaning machine is designed for operation within high-performance lines, the key priority in its development was given to reliability and endurance. The key structural elements are made of metal with increased thickness - this engineering solution provides high resistance to constant vibrations and mechanical loads, which is a guarantee of a long service life. All shafts and augers are designed for intensive work and are made with a significant margin of safety. Special attention is paid to the bearing assemblies - they are modern and reliable, now featuring an improved design that securely protects them during operation and simplifies maintenance. This approach of reinforcing every problematic element is a direct response to the operational problems of OVS-25 type grain cleaning machines in ZAVs, where an overload or the entry of a foreign object could lead to a critical breakdown and downtime for the entire line. As a result, we get a ready-for-integration cleaning module from the assembly line, which becomes a strong and durable asset, guaranteeing stability and confidence in the operation of your complex for many years to come.

One of the advantages of this basic module, the OVU-25U grain cleaning machine, is its exceptional flexibility and potential for further modernization. Every grain cleaning complex has its unique requirements, so we offer wide possibilities for retrofitting and implementing changes that will improve the productivity of your entire grain cleaning line and, consequently, its profitability. Depending on your technological process, the machine can be equipped with a discharge section (elevator) of the required length to feed the cleaned grain to the necessary height. For farms striving for maximum cleanliness in production, the option to install a high-efficiency cyclone instead of the standard dust separator is provided. However, the flexibility of modernization is not limited to the main units - by individual order, our engineers can adapt other parameters as well: select optimal pulleys and belts to match the speed of your line and grain material, change the overall dimensions for perfect integration into a limited space, or make other design adjustments. This approach allows you to receive an individually configured solution that fully corresponds to your current tasks and has the potential to grow along with your farm.
