It needs effort to keep a seed in good condition for a long spell of time. Seed cleaning equipment is a facility used to prepare seeds for safe storage with minimum risks of micro-organism action. This tedious process of chaff removal has been made easy using simple technologies as discussed below.
This requires a series of machines like gravity tables, air screeners, magnet to trap any pieces of magnetic metals, cylinder separators among others. These facilities are widely used to process seeds from crops such as barley and maize. Nevertheless, it is not possible to get a single equipment for seed cleaning that can work satisfactorily on all types of seeds.
In choosing the type of equipment for seed cleaning consider things such as the capacity of the machine in removing the specific plant remains on the seeds and the size of the specific seeds to be prepared. A good machine is one that accepts a wide range of seed sizes and this is achieved through use of screens of various sizes. Such facilities minimize the costs of operation.
A machine with one or two working elements is known as a simple machine while a complex machine is one with several normally including fans, screens and cylinder sorters. Due to the complexity of this procedure, there is need to have the screens with dimensions. Incorporating calibrations on the different screen sizes will help simplifying the input stage on the machine as various native seeds will have their own sizes. There are also mobile and stationery machines.
The machine operation is affected by the changes in width, length and thickness of the seeds. It is also influenced by the aerodynamic properties, surface conditions, the shape of the seed and its specific weight.
This technology is a low cost initial investment. It is also economical in maintenance with most parts readily and easily made available. There are no worries in searching for the spares and in some situations they are provided with extra for replacement.
There are very simple techniques deployed in the removal of dust and discarded materials from grains. Non-vital particles are easily taken away using effortless means. The process uses different ways of threshing and sorting through screens and airflows.
No matter how normal some seeds may appear, they may be non-viable for to be used since they have loss of weight. This can be due to immaturity, underdevelopment or feed by predators. Such cannot be separated by screening and thus necessitates airflow. Airflow is done through winnowing or aspiration. Winnowing is a technique which uses flowing air in a horizontal manner in such a way that heavy particles are separated from light. Aspiration is the use of vertically flowing air that suspends the light particles in form of a column.
Ultimately, it is important to note that the process can be harmful to human health and use of safety attire like dust masks, heavy boots, leather gloves is recommended. Plastic tubes and other containers of different sizes may also be used. Good ventilation is also required.
