CIMBRIA | TURNKEY | EAR CORN DRYING & PROCESSING | 3 | RECEIVING, HUSKING & SORTING The ear corn is received directly from the field and enters an area for sampling, testing and quality control. RECEIVING AREA The ear corn is tipped directly into the intake pit. The intake pit is equipped with a walking floor for gentle and even transfer of the ear corn into the belt conveying system from where it is conveyed into the husking and sorting area. HUSKING & SORTING A distribution conveyor fills the pre cells above the huskers, from where the ear corn is conveyed to the husking process by means...

EAR CORN DRYING PROCESS Drying of ear corn is a complex process, which in the past traditionally depended on operator experience. Given the high value of good quality seeds the process must be optimized in order to secure quality and minimize energy consumption while at the same time maximizing the plant capacity in a controlled manner using the latest automation systems to monitor, control and finally save all process data. Seed corn is usually harvested as ear corn with a moisture content of 30% to 40% and it subsequently needs to be dried down to 12-13% for safe storage. With such huge...

CIMBRIA | TURNKEY | EAR CORN DRYING & PROCESSING | 5 | SINGLE PASS DRYING The single pass reversing dryer is constructed with two rows of drying bins arranged opposite each other. The area between the bins is used for transport of ear corn out of the dryer. The ventilators blow hot air into the plenum. First upwards through the drying bin and out to atmosphere, later down through the drying bin and out into the atmosphere. Each bin has its own independent heating source and drying ventilator which are installed at the air plenum on the outside of the drying bin. Advantages of Single Pass...

DOUBLE PASS DRYING The double pass dryer is constructed with two rows of drying bins arranged opposite each other. Ear corn is transported from the dryer from shell out doors on the external bin walls of the dryer. The ventilators blow hot air through the bins containing the driest ear corn and into the lower plenums and then upwards through the high moisture bins and out into the atmosphere. The drying bins have a common heating source and drying ventilators which are installed at both ends of the dryer. Depending on the dryer size the double pass dryer is supplied with two or four...

CIMBRIA | TURNKEY | EAR CORN DRYING & PROCESSING | 7 | BOX DRYING AND HEATING SOURCES BOX DRYING Box dryers are mainly used for small batches and loose kernels recovery. The boxes are loaded into the dryer in the front end by a forklift. The box dryers are either for one or two rows of boxes. At the rear end, the heating and fan systems are placed. The distribution takes place via the common air channel in the dryer. HEATING SOURCE For the drying process, we provide heating systems for heating by liquid or natural gas, oil, steam and hot water. HEATING WITH GAS The most common used heating...

Shelling is a mechanical process where the corn kernels are separated from the cob. The shelling process must be done as gently as possible to reduce kernel damage to a minimum. SHELLING The Cimbria sheller operates with a corn on corn shelling action and is equipped with a sturdy steel housing with a forged rotor. The shelled cobs are conveyed to a cob bin for truck load out or to a dump area. PRE-CLEANER A Delta pre-cleaner is used for scalping of corn cobs and other large impurities in the upper screen layer. The lower screen layer is used for sifting smaller particles, soil and broken...

CIMBRIA | TURNKEY | EAR CORN DRYING & PROCESSING | 9 | During the process the corn must be stored for temporary storage and dosing. The silos are integrated into the plant flow for storing of • Shelled corn • Per-cleaned corn • Treated corn • Cob waste When filling the cells, the corn is cascaded at reduced speed in order to prevent damage because of high velocity. The product temperature in the single cells can be monitored continuously and the measurements are logged in the SCADA system. The cells are designed with aeration which facilitates the possibility of ventilation of the single...

In the fine cleaning process, under size as well as over size corn kernels which are not suitable for seed are separated from good FINE CLEANING It is of outmost importance that the corn seed is well cleaned. The Cimbria range of Delta cleaners are able to perform the best cleaning due to vibrator feeder securing an absolute even feeding and distribution on the screens. Moreover the highest % apertures on the market ensure maximum utilization of each square meter of screen. Finally a very efficient airlifting system will remove all light material. FLAT SCREEN GRADING When using a Cimbria...

CIMBRIA | TURNKEY | EAR CORN DRYING & PROCESSING | 11 | In the process of grading by size, seeds can be separated according to the criteria of width and thickness on one hand, and length and particle shape on the other hand. Calibration into different fractions can be made by the use of flat or round screens. WEIGHT SEPARATION The separation by weight is performed on a Cimbria Gravity tabel which efficiently will remove any stones or foreign seeds having the same length and width as the good product but a difference weight. The gravity table uses a fluid bed principle combined with a...
