Air screen cleaner diagram

Air screen cleaner.

Processing involved three steps Step 1. Pre conditioning : Isolation of seed from plant parts with which it was harvested e. Pre cleaning Removal of external materials like trash, stones, clods which are either in larger size or lighter in weight. No pre cleaning is required for hand harvested and winnowed seeds. The machineries involved in this operation are,.

Seed lots received from the field are often at high moisture content and contain trash and other inert material, weed seeds, deteriorated and damaged seeds, off-size seeds, etc. Seed processing is necessary in order to dry the seeds to safe moisture level; remove or reduce to the extent possible the various undesirable material, weed seeds, other crop seeds, deteriorated or damaged seeds. Other than this the seed lot heterogeneity in its physical characters like size, colour, shape etc. The seed lot is heterogeneous due to the following reasons. The inherent qualities such as germinability and vigour are exemplified by certain physical characteristics of the seed i. In its common usage in India, seed processing refers to all the steps necessary for preparation of harvested seed for marketing, namely, handling, drying, shelling, preconditioning cleaning, size grading, treating and packaging, etc. Seed Processing Plant Layout Planning Layout plan for construction of a seed processing plant should be carefully planned to ensure that the thorough seed cleaning, upgrading, seed treatment and other seed processing operations are carried out efficiently, without mixing and damaging seed lots, with a minimum of equipment, personnel, time and at minimum cost. The following factors should be considered in planning and designing a seed processing plant:. The key to efficient plant layout is a thorough knowledge of what needs to be done, and sound planning. First, the general sequence of processes involved between the time seeds enter the processing plant and the time they are cleaned, packaged and ready for shipment, must be charted. The sequence of operations depends upon the kind of crop and the initial quality of seed lot, type of contaminants, moisture content of the seed lot, etc.

Spiral separator Separation of seeds based on shape eg. Seed lots received from the field air screen cleaner diagram often at high moisture content and contain trash and other inert material, weed seeds, deteriorated and damaged seeds, off-size seeds, etc. No pre cleaning is required for hand harvested and winnowed seeds The machineries involved in this operation are, Scalper It removes the larger inert matter from jenfoxxx seeds.

Colour separator T he colour separator is used to separate discoloured seed, greatly of lower quality. Height will be kept to facilitate installation of the seed processing equipment and machinery. Scalper It removes the larger inert matter from the seeds. Roll mill To separate smooth seed from rough seed based on the surface texture especially the weed seed Maize sheller 1. These are highly sensitive. Air screen cleaner 1. At any rate, the effectiveness of magnetic separation depends on the components of the seed lot and on the powder and water used in the treating operation. Factors which determine the quality and quantity of seed cleaned include size of the perforations, the precision of the perforation, the angle at which the sieves operate, the amplitude and speed of movement of the sieves and correct cleaning and maintenance of the equipment. Receiving-cum-drying platform This area will be utilized to receive the raw seed and to sun dry small lots of crop seeds. The separator, which classifies seed according to its shape and rolling ability, consists of sheet metal strips fitted around a central axis in the form of a spiral. Stylosanthus B. The following factors should be considered in planning and designing a seed processing plant:. Lab Model As the cylinder revolves, it creates centrifugal force which helps to hold the seed in the indent.

VX Series Pre-Cleaners. Power, kw hp. Up to 7.

No pre cleaning is required for hand harvested and winnowed seeds The machineries involved in this operation are, Scalper It removes the larger inert matter from the seeds. He can thus maintain closer supervision of all operations. Specific gravity separation 2. The orbit of round seed increases with speed on its flight around the axis, until it rolls over the edge of the inner flight into the outer flight where it is collected separately. Rate of vibration of sieve This can be adjusted either to increase or to decrease the speed of the rolling seeds on the screen. Physical characteristics normally used to separate seeds are size, shape, length, weight, colour, surface texture, affinity to liquids, electrical conductivity, etc. Processing area The processing area should be situated between the shed and ventilated storage building. Precautions in handling processing equipment All machine adjustments like the speed, oscillation and duration should be perfect. To scarify the hard seed mechanically to improve the germination of seeds. Surface texture : Rough from smooth surface seed- dodder mill 6. The air column thus stratifies the seed mixture into vertical zones of relative weight with the heavier seed lying on the deck and the lighter seeds lifted up to the top of the seed mass. Seed that differs in colour is detected by the photo cells, which generate an electric impulse. If its colour or shade falls within the reject range, a blast of compressed air deflects the seed and sends it in to the reject discharge spout. A sequence of processing machines to be installed is shown in Fig.
