Yes, You can use kitchen oven to dry (a small amount of) plant materials for biomass assessment after connecting thermometers or any accurate temperature measuring tool to define the degree at which you dry. Thanks
Drying has many purposes.
If you are drying the biomass to prepare for other tests; e.g. for ultimate analysis, then there are standard methods that can be used. In many works by others, ASTM are referred to; e.g. ASTM E1756-08(2015), for which the biomass is dried at 105 degree Celsius. Hence, if the kitchen oven that you're using can maintain this temperature, then it'll be fine. Otherwise, it is feared that higher temperature may cause material disintegration or reactions (though not visible to the eyes).
If your drying is intended for tests such as gasification or combustion, then the kitchen oven may be fine as long as the biomass material is not experiencing disintegration or reactions. In other words, the temperature should be just enough to remove water from the biomass. Drying under the sun can also serve the purpose although slow.
Dear Evans Kyei,
Gamal B. Abdelaziz,
Shaharin Anwar Sulaiman,
Yes definitely you can use it,
But temperature measuring has much importance, according to your desired standards and conditions.
Through a drying process, moisture can be largely removed from biomass. The result is a reduction in the weight of the biomass. This leads to a reduction of the processing costs, as well as of the costs for storage and transport. The dried end product is frequently used as a plant nutrient or it can be used as a fuel.

Thanks.
Yes, biomass can be dried without a lab oven, but experiment results will likely change depending on drying method. Plant sugars (carbohydrates) change dramatically between fresh and dried. Subsequently, the type of biomass of original carbohydrates (fresh sample) will produce different results than open-air fan drying with low humidity which can also be different than if using a microwave oven, conventional gas, electric, biomass oven, freeze drying, irradiation drying, or using industrial heat.
One example for effects of drying, see Houghton, Tracy P., et al. https://bioenergy.inl.gov/Journal%20Articles/The%20effects%20of%20drying%20temperature%20on%20the%20composition%20of%20biomass.pdf.
Carefully select uniform sample of biomass since plant components, harvest timing and biomass preparation methods change results. Results can vary greatly. See example two (dry matter analysis), example three (harvest timing), and example four (preparation and extraction) of my patent (U.S. # 8,641,910) "Systems and Processes for Producing Biofuels from Biomass," by Gary Wietgrefe http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=95&f=G&l=50&d=PTXT&s1=Wietgrefe&p=2&OS=Wietgrefe&RS=Wietgrefe.
For microwave drying, see Smith, Megeen, C. https://journals.uair.arizona.edu/index.php/jrm/article/viewFile/7625/7237.
Irradiation drying see Chen, N.N., et al.Article Far-infrared irradiation drying behavior of typical biomass briquettes
.Evaluate heat sources, for example see Hanning Li, et al. https://research.ncl.ac.uk/pro-tem/components/pdfs/EPSRC_Thermal_Management_Sheffield_Journal_paper_2_Biomass_Drying_Jan_2011.pdf.
Vented forced convection oven is preferred but you can use kitchen oven with heat transfer mechanism natural convection and radiation. It is slower and less accurate but accepted when connecting suitable temperature and weight measurement instruments.
Yes, this is possible, however you will need to calibrate to ensure you work with the set temperatures. you should also note that the set of experiments being considered should be treated under the same confitions
Thanks to all of you for your useful comments. I have learned a lot from them. It looks like most of the recommendations fit the kind of biomass measurements I want to do (i.e simple drying and weighing of the dry matter) so I will definitely try it out with the kitchen oven. Thanks to all of you once again.
Hi Evans Kyei ! Could you tell me if it worked well? I'm wondering the same as you, so learning from your experience would be great!
if the temperature of kitchen oven is research 105 0C, it is used , if temperature below 105 0 C, it is not used
Thank you Murwan khalid Sabahelkhier
Please can you explain how to define the temperature 105 C?
Why 105?
It is easily use thermometer for chick temperature in side kitchen oven
Thanks but this is not my speach
I mean why below 105 you can not use it? Why above 105 you can use it? Why 105 specially
Sir Evans Kyei How much time (in mins. or hrs.) did you follow to dry your biomass materials? We also have to assess a biomass, however, we also cannot access a lab oven. Your response is truly a help for us. Thank you!
