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.

Short seeds are held in the indent until the cylinder turns to the point where the indent is inverted enough for gravity to cause the seed to fall out of the indent. Heavier seeds are good storers and expresses maximum field establishment, air screen cleaner diagram. Each disc contains many under cut pockets.

Screens have been used for centuries to size product and help remove contaminants as it was faster than hand picking. Screen separate by size, typically by width or thickness. Screens can perform three functions, scalp, sift and grade. Scalp screens allow the desired product to fall through the screen, but overwidth or thick contaminants are kept on top of the screen. Sift screens allow the undersized contaminates to fall though the screen but keep the desired product on top of the screen. Grading screens are used to categorize the good product into specific size dimensions. Modern Screen cleaners will usually incorporate scalping and sift screens to deliver three product streams…Oversize, desired product and undersized. The Orion is available in four models offering screens areas of 72 square feet of screen area, 6.

Specific gravity separator Seeds of the same size and general shape can often be separated because they differ in specific gravity or relative weight. Almost all seed must be cleaned by air-screen cleaner before specific specifications can be attempted. Removal of badly damaged, deteriorated, insect damaged crop seed and stones from good seeds. Type of Layouts There are three main types of processing plant layouts: multistorey, single level and combination. 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. Most magnetic cleavers pass the seeds over a revolving drum which has a high intensity magnetic field. Sunflower thresher For removal of seeds from the head 9. The seed separators, elevators, conveyors and storage bins should be so arranged that seeds flow continuously from beginning to end, and yet be flexible enough to bypass a machine or return to a part for re-cleaning. Colour variation may also occur due to immaturity or disease. The seed are then discharged from mixing chamber and brought into contact with a powerful magnet, which removes the iron coated seeds. This machine separates seeds of the same density but of different size and seeds of the same size but of different densities. Materials separated during processing. Skip Navigation.

VX Series Pre-Cleaners.

The principle of floatation is employed here. As the rollers turn up and out, seeds that are rough or have sharp or broken edges are caught by the nap of the fabric covering the rollers. Adjustments 1. Groundnut decorticator To shell the kernel seed from the pods 8. Pre cleaning Removal of external materials like trash, stones, clods which are either in larger size or lighter in weight. You are currently using guest access Log in. The unit consists of a vibrating or rotating screen or sieve having perforation large enough to allow the rough seed pass through readily. Cleaner cum grader The dried seeds should be cleaned and graded with help of a cleaner cum grader. Upgrading machines Based on electrical properties removes Johnson grass from sesamum seeds Specific utility. In lengthier seeds it maintains the size of seed breadth and length. Screen or sieves: Perforated metal sheet with specific size of perforation in which there are two types. The electronic colour sorter views each seed individually with photo electric cells. Surge bins can handle variations in individual machine capacities. Its operations, Seed — rotating disc- centrifugal force — thrown — huller- - suction chamber- removes lighter seeds.
