  1. 1. A presentation on BFRI and BFIDC tour, 2015 Institute of Forestry and Environmental Sciences, Chittagong University 6th Semester, Group-6 Course Title: Saw Milling, Seasoning and Preservation
  2. 2. Contents  Preface  BFRI  Wood seasoning and timber physics division  Wood working and engineering division  Veneer and composite wood products division  Wood preservation division  BFIDC  FIDCO
  3. 3. Preface In our 6th semester B.Sc (hons) in Forestry we have a course titled ‘Saw milling, Seasoning and Preservation of Wood’. To get practical knowledge about this course our honorable course teacher Md. Akhter Hossain conducted a fieldtrip to BFRI and BFIDC on 28 december, 2015.
  4. 4. BFRI at a glance Previous name Forest Products Research Laboratory (FRL) Present name Bangladesh Forest Research Institute (BFRI) Established 1955 Location HQs at Chittagong City Land Area 1100 ha. (including 28 ha. at HQs) Disciplines 11 research Divisions under Forest Management Wing, 06 under Forest Products Wing and 02 Common Services Divisions Field Station 21 with a total area of 1072 ha.
  5. 5. Wood seasoning and timber physics division  Under Forest Products Wing, BFRI. Research Activity:  Physical properties of wood and  Wood seasoning process Achievement:  Invention of wood seasoning solar kiln is the best achievement of this division.
  6. 6. Wood seasoning  Seasoning is the procedure of reducing moisture content at a desired level. Process of Seasoning: 1. Air seasoning 2. Kiln seasoning 3. Solar kiln seasoning Among these three BFRI is now only practicing Solar kiln seasoning.
  7. 7. Solar Kiln Dr. M. A. Sattar invented Solar kiln in 1980. Features of Solar kiln:  The Solar kiln is comprised of a wooden frame superstructure.  The roof has been covered with ordinary thick glass and has an inclination towards the south at an angle equal to the latitude of the location to ensure maximum absorption of solar radiation.
  8. 8. Continue….  The walls have been made with a layer of white transparent polythene sheet or glass.  Corrugated galvanized iron sheet, painted black on both sides have been fixed beneath the glass roof as an absorber of solar radiation.
  9. 9. Continue….  One 24inch diameter fan driven by ¼ horse- power motor has been incorporated for air circulation.  Two vents, one inlet and another outlet, of 8inch*9inch have been provided for the control of the humidity inside the kiln.  Dimension of the kiln: 12ft long, 8ft wide, 9ft high at the north wall and 5.5ft high at the south wall.  Bearing capacity: It can accommodate 125 cft timber of maximum 7.5 ft long.
  10. 10. Physical Properties Machines:  Moisture meter  Universal Testing Machine (UTM)
  11. 11. Continue… UTM Moisture Meter
  12. 12. Continue… UTM: UTM is used for measuring-  Static Bending Test (modulus of rupture and elasticity)  Compression parallel to grain  Compression perpendicular to grain  Nail holding capacity  Cleavage test  Tension perpendicular to grain  Toughness  Shear test
  13. 13. Wood working and engineering division  Under Forest Products Wing, BFRI. Research Activity: 1. Saw milling process 2. Saw doctoring 3. Furniture making and development
  14. 14. Continue Achievement:  They have invented some technologies to produce novelty items from different colored wood gluing together.  One of the special achievement of this division is the invention of technology for using Rubber wood in furniture making.
  15. 15. Wood Preservation Division  Under Forest Products Wing, BFRI. Research activity:  Enhancing durability of wood Achievement:  They have invented BB (Boric acid+Borax), CCB (Copper Sulphate, Sodium di-chromate, Boric acid) solutions for wood preservation.
  16. 16. BB solution Elements:  Boric Acid(H3BO3), Borax(Na2B4O7.10H2O) Ratio for 10% solution:  Boric Acid:Borax=2:2 and 9 times water Use:  Used in the preservation of interior furniture making wood.
  17. 17. CCB Solution Elements: Copper Sulphate (CuSO4. 5H2O), Sodium di-chromate (Na2Cr2O7.2H2O), Boric acid (H3BO3) Ratio for 10% solution: CuSO4.5H2O: Na2Cr2O7.2H2O: H3BO3=2:2:1 Use: Used in the preservation of wood for exterior construction purpose.
  18. 18. Veneer and Composite Wood Division  Under Forest Products Wing, BFRI. Research activity:  Ensuring maximum utilization of less used woods and wood residues  Developing technologies for making furniture from bamboo.
  19. 19. Continue… Procedure of making bamboo furniture:  Splitter: For splitting bamboo into pieces  Four side planner: For resizing bamboo pieces  Seasoning: At 20-25% moisture content level  Treatment: Dipping in BB solution for 48 hours.  Seasoning: At 8-10% moisture content level  Hot pressure treatment: Using urea formaldihyde glue at 150 C temperature heat and 200 psi pressure
  20. 20. BFIDC at a glance Bangladesh Forest industries Development Corporation(BFIDC) was established in 1959. Previous name was Pakistan Forest industries Development Corporation(PFIDC) Headquarter of BFIDC is located at 73 Motijheel Commercial Area, Dhaka-1000. In Chittagong BFIDC is located in Chandgaon.
  21. 21. Continue… Wood preservation division:  In BFIDC, now a days they make revolution by marketing rubber made furniture which have great positive impact on the low supply of wood crisis. Rubber wood is very cheap in market value but with some preservation process it may provide a very good and durable furniture.
  22. 22. Continue…  Wood preservation done by two way. They are:  1.pressure treatment  Establishment:1959- 1960  Pressure: 100 PSI  Time:1-3 hour  Preservative: 10% BB solution  65ft in length and 1200cubic ft lumber can preserve in the cylinder at a time
  23. 23. Continue… Steam Control room:  Cylinder-2  Length-90 ft
  24. 24. Continue… 2.non-pressure treatment  They also preserve the wood by dipping the wood into water mixing with chemical which prevent wood decay and other harmful process when the pressure process is delayed.
  25. 25. Continue… Saw milling division: They have two saw mill of their own .
