Sunflower Hulls Degradation by Co-composting with Different Nitrogen Sources
Environmental Technology, 2006The decomposition of sunflower hull and its mixtures was examined under mesophilic (M) and thermophilic (T) temperatures during 100 days. Thermophilic conditions were used to define the composting process. Vetch, alfalfa and ammonium nitrate were used as nitrogen co-substrates, in 6 treatments: sunflower hulls alone (C), sunflower hulls plus ammonium ...

Chemical composition of sunflower seed hulls
Journal of the American Oil Chemists' Society, 1971AbstractThe major components of the sunflower seed hull, lipids, proteins and carbohydrates were studied Lipids represent 5.17% of the total hull weights, 2.96% of which is wax composed of long chain fatty acids (C14–C28, mainly C20) and fatty alcohols (C12–C30, mainly C22, C24, C26).

Sunflower Hull Flour as a Potential Dietary Fiber Supplement
Journal of Food Science, 1983ABSTRACT Confectionery hull flour (CHF) and oilseed hull flour (OHF) were evaluated as potential dietary fiber supplements. Analyses included: proximate analyses, neutral detergent fiber, acid detergent fiber, acid detergent ligrdn and buffered acid detergent fiber, water‐ and oil‐holding capacity, pH, cation exchange capacity ...

Separating Kernels and Hulls from Oilseed Type Sunflower Seed
Transactions of the ASAE, 1980ABSTRACT A flowsheet was developed and tested for separating hulled oilseed type sunflower seed into nearly pure kernels and hull fractions. Design of the flowsheet was based on the principles of (a) sizing of seed to remove small seed before hulling in order to minimize passage of unhulled seed through the first separating screen following the huller;

Fermentation of sunflower seed hull hydrolysate to ethanol by Pichia stipitis
Bioresource Technology, 2008Ethanol production from sunflower seed hull hydrolysate was evaluated using Pichia stipitis NRRL Y-7124. The hydrolysate prepared with 0.7 M H2SO4 at 90 degrees C was fermented as substrate in shaking bath experiments at 30 degrees C. In a group of experiments, the influence of various detoxification methods on the fermentability of hydrolysate was ...

EQUILIBRIUM MOISTURE CHARACTERISTICS OF SUNFLOWER SEEDS, HULLS, AND KERNELS
Transactions of the ASAE, 1991ABSTRACTThe equilibrium moisture content (EMC) of sunflower seeds, hulls, and kernels at 10, 25, 40, and 55° C were determined by equilibrating the samples to known relative humidities above saturated salt solutions. EMC of the hulls was higher and EMC of kernels was lower than that of seeds at all temperatures and equilibrium relative humidities (ERH).

Bench-scale Processing of Red-colored Extracts from Sunflower Hulls
Transactions of the ASAE, 1994Extracts were prepared from the hulls of purple-hulled sunflower, then processed using clarification, evaporation, and spray drying. Addition of citric acid to solvent or raw extract substantially reduced pigment yield, probably by precipitation, but the loss was diminished if citric acid addition was delayed until after evaporation or spray drying ...

Fire hazard and heat of combustion of sunflower seed hull pellets
Journal of Thermal Analysis and Calorimetry, 2017This study is concerned with the investigation of the impact of heat flux on the fire hazard and the effective heat of combustion of sunflower seed hull pellets. Pellets produced by pressing common sunflower seed hulls (Helianthus annuus L.) were investigated. The samples were dried on water content of 0 mass% at a temperature of 103 ± 2 °C.

FLASH DRYING IN RELATION TO HULLING OF SUNFLOWERS EED AND OATS
Canadian Journal of Research, 1947A laboratory flash drying unit with continuous feed is described. In tests on sunflowerseed and oats it was possible to lower the moisture content of the hulls several units per cent without appreciably changing the moisture content of the meats. The effect of this change in the moisture distribution between meats and hulls on hulling efficiencies was

Performance of Coated Extra-Large Hulled Confectionary Sunflower Kernels for Precision Planting
Agricultural Research, 2017Extra-large (XL) confectionary sunflower seeds are too large to plant with current precision planters, and a high proportion of seed does not emerge upon planting. Hulling the XL seeds and then coating the kernels has been proposed to improve the viability and plantability of these seeds. Therefore, the objectives were to evaluate the effect of various
