Stages of technological process

  • 1

    Receiving

    It is the first stage of the process. The ears of corn from the fields are weighed and unloaded to the intake pit. Then the vibratory feeder carries corn to the belt distribution conveyor and after that to the peeling machines.

  • 2

    Purification and selection

    The ears of corn are peeled on the 12-row husking machines “Power Husker”. Then they get to the sorting tables where the manual sanitary sorting out happens (small-sized, affected with disease or damaged ears of corn go to wastes). After weighing quality ears of corn go to the next stage – drying.

    Drying

    The temperature of drying ears of corn is 36-38 C° (dryer PETKUS MKT-20).The drying process lasts for about 72-120 hours depending on the hybrid structure. Constant control over humidity takes place at this stage. The quantity of samples taken depends on humidity of corn (every 8 hours when humidity is 38%, every 4 hours with 16-20% and every hour with 16% of humidity). The drying process is finished when humidity of the corn ears equals 13%.

    Peeling

    Dried ears of corn get into the sheller (HS60/ 2SC2000 by AEC - combined machine for shelling and preliminary cleaning of corn), the productivity of which is 30 tons per hour. Here corn seeds are separated from the corncob. At this stage small grains and leftovers are removed . After this corn is packed to big bags and taken to the temporary storage.

    Storing

    Grain is stored in big bags in certified warehouses. Minimal storing term is 15 days.

    Calibration

    Calibration line is a set of machines by leading world producers: PETKUS, KAMAS, Westrup, Simotek, with productivity 140 tons per day. At this stage the leftovers and small grains are sifted, while the quality grain is separated in four groups (large round, large flat, medium round, medium flat). The last phase of calibration is the sorting machine where the grain with inappropriate physical characteristics is removed.

  • 7

    Treatment

    It is the process of covering the grain with the treatment substance against disease and pests. In this process we use batch chemical treater CT200 by PETKUS. For grain not to stick together it undergoes the phase of drying completion.

  • 8

    Packing

    Grain is packed on automatic equipment ARODO (GRS), the daily capacity of which runs up to 4 thousand bags. We have a full control of the processing (taking samples from every 5th bag) and packing.

  • 9

    Unloading

    Packed finished grain is transported to certified warehouses, where it is stored before dispatch by logistics department to final consumer.

  • 10

    Laboratory

    Laboratory includes three units: production engineering laboratory, corn laboratory and crop laboratory. LNZ Group lab corresponds to all governmental norms and standards and performs a wide range of modern grain analysis. We plan to perform infotech analysis as well. It will give us the possibility to analyze the whole grain in 1 minute, defining protein, oil, starch, gluten content and moisture.
