(NIL) KEYWORDS . picasso, tmci, recon, tobacco, sheet, rcb, monique, es, ch, trial, tarragona, asta, hosokawa, micropul, db, grinding OBJECTIVES The aim of this project is to create aniin-house capability for TI.;CI, a reconstituted tobacco process using a different slurry systemto:thalt of RCB, ais requested by TTG kichmond. TheRCB!/' Monique sheet line iniOnnens appeared suitable for attaininy this objective. The project was implemented and now allows for process and prod'uct development trials and production of sheet materials using TMCI technology with various binder systems for liruited peried's of time. It also involves our assistance, together with PM Rictimond, toi Tabacallera SA in Spain for sheet development and the start-up of TI,1CI instal'lations in Tarragona and Cadiz using the PP~~1 binder system. STATU S Based cni the results from the three week trial prograr; in Tarrag,cna, Spain, it was finally arreed between PM, TMCI and 1'abacadera to prepare additional finely grounc: Spanish tobacco ior further development work in Tarragona.on ASTA sheet (1, 2). tis the WILLIAMS roller mill in Cadiz is not yet operational,, the tobacco will be ground at NU WAY Tobacco Company in South Windsor, Connecticut,, USA. Due to some delay in the shipment, the grinding will be done only at the beginning of October 195U. The trials in liarragona are planned for November 1988' As reported earlier, about 350 kg,of the feedstock currently usEd, onRCB%Llon,ique in O'nnenswas sent to HOSOnAtti'AMICROPUL in G'ermany~or some pre-trials in producing a finely ground product in.their pilot plant using,one of their impact mills.

RESEARCH AND DEVELOPMENT, NEUCHATEL - QUARTERLY REPORT Based on these pre-trials, carried'.out in July 1988, we decided' to ship about 5''U00 kg of feedstock to HOSOKAWA in Germany. After contact with R&D Richmond, it was decided~to grind the tobacco to two different sizes. This was discussed with HOSOi<AGdA and accepted by them as being feasible (3). The tobacco was shipped on August 24, 1988, and~will be back in~ Onnens at the beginning of October (3). The trials in Onnens using this finely ground tobacco on the RCB/Monique-TMCI instal- lation are planned for November. REFERENCES (,1)l LUthi-N.
