The First five characteristics of Paddy Rice

Size and Shape

The length of the paddy grain is variable, even inside an assortment, on account of variety in the length of the awn and the pedicel.

 It is thus that the sort of paddy is not controlled by the length of the paddy grain yet by the length of the cocoa rice portion. In sifting, it is vital to watch when the paddy grain will sever its panicle, in light of the fact that the pedicel ought not be a part of the grain, or else it will have a decreased processed rice recuperation through the expansion of "husk" creation. (Belsino, 1980) 

Paddy rice can be arranged in view of the length of the entire cocoa rice grain. 

a. Extra-long paddy with 80 % of the entire chestnut rice parts having a length of 7.5 mm or more. 

b. Long paddy with 80 % of the entire cocoa rice bits having a length of 6.5 mm or all the more, however sorter than 7.5 mm. 

c. Medium paddy with 80 % of the entire cocoa rice pieces having a length somewhere around 5.5 and 6.5 mm. 

d. Short paddy with 80 % of the entire cocoa rice pieces shorter than 5.5 mm.

Angle of Repose

Paddy frames a total cone when it is vertically emptied on a level surface. The point of the side of this cone-formed mass of grain, measured after the stream of grain has totally ceased, is the edge of rest. This point differs for every kind of grain and depends much on the smoothness of the surface of the grain. 

The edge of rest is likewise specifically subject to the dampness substance of the grain. At a dampness content level of 20%, the point of rest for paddy will be more prominent than for dry paddy at 14% dampness content. The point of rest of rice is 450 (paddy rice), 350 (hulled rice), and 300 (cleaned rice). (www.lemanco.com/html/densities.html) 

These properties are critical in the development of mass storerooms and the computation of the measurements of middle of the road holding receptacles of a given limit.

Angle of Friction

The point of rubbing alludes to the edge measure from the level at which paddy grain will begin moving downwards once again a smooth wooden surface with gravity releasing the paddy grain. This contrasts for every kind of grain and normal for the surface, since it depends much on the smoothness. Likewise, the dampness substance of grain affects the point of grating the plot for wet grain is more noteworthy contrasted with dry grain. The coefficient of erosion of rice is 0.4 (paddy rice), 0.364 (hulled rice), and 0.35 (cleaned rice). 

This point of grating is imperative in the development of self-emptying holding containers and mass storerooms. It likewise assumes a part in the development of grain release gushes.

Bulk Density

The mass thickness alludes to the proportion amongst weight and volume of grains. It is typically communicated in kg per HL, Ib/ft3 or kg/m3. The mass thickness of rice is 20-21 Ib/ft3 (paddy rice), 45-49 Ib/ft3 (hulled rice), and 30 Ib/ft3. 

The thickness information are critical in the estimation of the measurement of mass storerooms and middle property containers of given limit. It likewise shows the virtue level of the grains since the nearness of light outside matter diminishes the grain thickness.

Husk Surface

The husk surface is fairly harsh and rough through its high silica content. It is therefore that elastic moves of the hullers wear so quick, that pre-cleaning machines have many parts which habitually should be supplanted, wood screws utilized for paddy transport turn out to be sharp, lift release gushes, particularly twists in spouts and lift containers wear so rapidly, and that parts of the husk suction apparatuses in direct contact with the husk must be repaired or supplanted frequently. (Belsino, 1980) 

In rice processing gear, the harsh surface of the paddy grain contrasted and the smooth surface of the cocoa rice assumes an imperative part in the assurance of particular plan criteria.
