“…Unfortunately, those criteria rule out many products of greatest interest to papermakers. Larsson and Orloff (2001) found more promising results when using dwell times corresponding to extended nip pressing. Both paper dryness after the nip and the resulting paper strength were judged superior to what was achieved by conventional pressing, then drying.…”

“…Such an arrangement provides volume for the escape and possible condensation of both water and steam from the paper web (Back 1991;Boerner and Orloff 1994;Larsson and Orloff 2001;Lucisano et al 2003). In principle, rapid evaporation of water at the heated surface can be expected to create superheated steam, which then tends to push water and steam through the sheet and out the other side.…”

Prospects for Maintaining Strength of Paper and Paperboard Products While Using Less Forest Resources: A Review

Paper production requires large amounts of cellulosic fiber, whereas the world's forested lands and croplands have a finite capacity to supply such resources. To deal with likely future pressure on forest resources, as well as to hold down costs of materials, publications examined in the preparation of this review suggest that the paper industry will need to implement several concurrent strategies. In particular, the industry can be expected to view recycling as a central part of its activities. Basis weights of various paper-based products can be expected to decrease over the coming decades, and more of the fiber content will be replaced with fillers such as calcium carbonate. Such trends will place intense demands upon chemical-based strategies to enhance the bonding within paper and paperboard. Based on the literature, further progress in reducing the amount of new forest resources used to meet a given set of paper product requirements will require a combined approach, taking into account various fiber attributes, nanostructures, novel concepts in bond formation, and advances in the unit operations of papermaking.

“…Larsson and Orloff [24,25] performed experiments with an MTS laboratory platen press with longer press pulses in the range 32-64 ms. The moisture ratio change increased from 0.6 to 0.8 kg water /kg dry matter when the press impulse was tripled.…”

Drying of paper during 2000-2018 is reviewed. The review includes new drying processes, multi-cylinder dryers, tissue and impingement drying, TAD-drying, infrared drying and energy use for drying of paper. It includes general aspects of infrared dryers but not drying of coated papers. Paper quality aspects, paper shrinkage and paper isotherms are not included. Impingement drying has been the most successful new technology with several applications while others such as impulse drying has not been commercialized mainly due to problems with paper quality parameters. One promising development is the introduction of steel instead of cast iron cylinders with increased heat transfer reducing the number of cylinders. Future research should focus on modeling the internal transport phenomena and to couple these phenomena to paper shrinkage and quality parameters. The influence of the fabric for the drying process needs more attention, understanding the drying process for new components such as microfibrillar cellulose in the stock and reducing energy use and increasing the amount of renewable energies for drying of paper.

“…Beloit research facilities tested a variety of pilot scale configurations, including the addition of a short and regular shoe press and hover press, to eliminate delamination problems . Most recent, test trials have documented an increase in speed and an increase in speed, press dryness, and strength characteristics compared to existing technology (Orloff et al 2000, Larsson and.…”
