MEPS 530 Project Study 1 Heated-air Hopping Layered dryer
CHAPTER 1
Introduction
Some farmers who don’t have irrigation system, plant rice during rainy season so, they have the difficulty of drying their grains after harvest. Aside from these, drying the grains under sunlight takes longer time, more effort in handling to the drying site, scraping or ricking, guarding from animals, collecting after drying, and another is that the possibility of the grains to be mixed with stones, leaves of tree, and dust in road drying and field drying.
There are many designs of grain dryer existing. Basing on the design, the researchers gather the advantages and focus the disadvantages of each design. And one major problem of some design is that the uneven drying of grains due to the thickness, steadiness of the grain and uneven distribution of heated air to the grain.
Finding ways for that problem, the researcher develop a new design that could dry the grains evenly, the grains are moving while drying and even distribution of heated air. Heated-air hooping layered dryer is a Mechanical Device that reduces rice grain moisture content into a safe level for storage and for milling purposes. It is simple, can consume small areas upon construction and can dry rice grains in a moderate mass in tons per hour. It can be use personally or privately especially for those farmers who have large harvest because it can be erected inside the house. Using this device makes the grains ready for storage and milling in a convenient time, no worries and less effort.
General Objectives
This study generally aims to make a hopping layered dryer that can consume small area, medium size and medium capacity that could be used in homes and could compete to the performance of the existing grain dryer preferably use now a days.
Specific Objectives
1. To be able to determine the power requirement of the electric motor to be use.
2. To be able determine the diameter and distance between pulleys for belt length and speed reduction.
3. To be able to
