Problems in High Moisture Paddy

Rice is perhaps the grain that has been cultivated for a very long time. It is occupying approximately 9% of the total arable land. It is the second cereal in significance for the human diet, after wheat. It is at present the food base of a two-third population of the world.

Rice is perhaps the grain that has been cultivated for a very long time. It is occupying approximately 9% of the total arable land. It is the second cereal in significance for the human diet, after wheat. It is at present the food base of a two-third population of the world.

It is well known that paddy drying is essential for its safe storage. You can expect a better storability of the paddy if the moisture content is within safe limits. As a rule of thumb, 1 % decrease in the moisture content of the grain doubles the storage life. But drying of paddy is not easy. The high humidity is a serious factor obstructing appropriate drying and storage of grains.

A certain level of moisture content should be maintained in rice and this depends on the time for which it is going to be stored.

  • 18% for 2 weeks
  • 14% or less a month
  • 13% or less for 8-12 months
  • 9% or less for long-term storage

There are many processes of drying:

    1. Field drying: It is done in a field after cutting rice panicles in fields and then stacking them into piles and racks. It is most primitive of them all.

 

    1. Sun drying: This labor-intensive method is preferred by small farmers. This is inexpensive way of drying paddy

 

    1. In-store drying: Paddy is dried during storage by controlling the level of humidity in the air. It is a slow process.

 

  1. Batch dryer: It may lead to uneven drying and usually used by farmers and rice millers.

Storage of high moisture grain is a grave problem farmer facing. Traditional methods of sun drying are still in practice but have sure disadvantages such as

  • unreliability
  • uncontrolled heating of grains
  • thermal stresses leading to grain fissures
  • vulnerability to infestation in open
  • Losses due to birds

Use of mechanical paddy drying offers a number of advantages over old-school methods and some of the benefits are as follows –

  1. Sustaining the quality of paddy
  2. Safe drying even during rain and at night
  3. Convenient control of drying parameters
  4. Significant saving on the labor cost
