Weight loss during drying During drying paddy grain will loose weight due to loss of moisture: W i = Initial weight [g] W f = Final weight [g] Example: 1000 kg of paddy is harvested at 25% MC and dried down to 14% MC what is the final weight of the dried grain?

Air Drying Characteristics of Apricots

Sulfiting‐drying using 80–1000 ppm SO 2 at any temperature in the range 50–80C was found to be the best treatment Thus sulfite was the major factor in controlling dry apricot quality and would be hard to reduce Drying time was reduced by 50% when apricots were dried at 80C compared to 50C and blanching reduced the time by 10

Relationship between seed moisture content and equilibrium relative humidity (eRH) during seed drying for 20 rice accessions (data shown in Fig 1) All eRH measurements were made at between 208 and 247 C Seeds were dried either immediately in the dry room or initially dried in the batch dryer

Seed Drying Principles Moisture Management and Storage

the seed life is halved Moisture content of seeds is the most important determinant of the life span of seeds In addition low moisture content will not favour the growth of fungi nor insect pests Hence it is of vital importance to dry seeds to low moisture level of 6 - 8% and to store them at low temperature ie at 20 C for short term

Effects of Temperature Light and Seed Moisture Content on

The aim of this study was to investigate the effects of different temperatures light regimes and seed moisture contents on germination of the palm Euterpe precatoria in the Arecaceae family For the study of light and temperature the experimental design was entirely randomized treatments were arranged in a 6 2 factorial scheme [six temperature conditions (20C 25C 30C 35C 20

MOISTURE CONTENT BY THE OVEN

Various methods for measuring the moisture content of wood are described by the American Society for Testing and Materials in publication ASTM D4442 These include two oven-dry methods a distillation and what the standard calls other methods In the solid wood products industry we most often define moisture content on a dry basis

A Guide to Forest Seed Handling

The relationships of seed moisture content on a wet weight or fresh weight basis to seed MC on a dry weight basis and of the equilibrium moisture content of seeds to the relative humidity of the surrounding atmosphere are important in seed processing and are explained on pp 121–125 They are equally important in seed storage

A comparison of methods for drying seeds: vacuum freeze

Drying rates using silica gel or a freeze-drier were comparable but lower water contents could be obtained using silica gel also silica gel was readily available and the daily rental fees made the cost of freeze drying prohibitive thus drying using silica gel was the preferred method Keywords: seed moisture content freeze drying silica

Role of Relative Humidity in Processing and Storage of

The principle underlying this method is the elimination of water from the seed by drying precisely for prescribed duration and temperature The moisture content is expressed as the percentage of the seed dry weight For determining the seed moisture content about 1-2 g seed sample was drawn randomly in three replications of each accession
