Description

(54 СПОСОБ СУШКИ ЖТЩЕНОГО ШПОНА(54 METHOD FOR DRYING HARDENERED VALVE

Изобретение относитс  к фанерной промшп ленноети, Иввестен способ сушки лущеного шпона в роликовых сушилках с паро вым обогоевом при температуре агентасушки 13D-140 C, Цель изобретени  - ускорить процесс сушки при высоком качестве высушиваемого шпона. Достигаетс  это тем, что сырой шпон предварительно пропускают черев псевдоохихенный слой мелкозернистого инертного материала при температуре 250-270 С. довод  его влажность до 20-25%, а затем выдеохивают в плотных стопа в течение 2-3 часов. Пример. Листы березового лущвного шпона толщиной 1.5 им с начальной влахностыэ 80 помещает в псевдоохихенный слой инертного мелкозернистого-материала при температуре 260 С на 0,3 мин. После этого листы шпона влахностдо 0 укладывают в плотные стопы дла выравыиБани  влашости по площади листов. Врем  выдержки в стопах составл ет 2-3 часа. После выдерживани  в плотных стопах листы шпона пропускают через роликовую сушилку с парсвым обогревом при температуре 130 С. В течение 5 мин листы шпона высыхают до влажности 6%. ПРЕДМЕТ ИЗОБРЕТЕНИЯ Способ сушки лущеного ипона в роликовой сушилке с паровым обогревом при температуре агента сушки 130-140°С, от л и ч а D щ и «с   тем,что, с целью ускорени  процесса сушки при высоком качества высушиваемого шпона, последний предварительно помещают в псевдоохихенный слой мелкозернистого инертного материала при температуре 250-270 С, высушивают до влахности 20-25%, затем выдерхивают в плотных стопах в течение 2-3 часов.The invention relates to plywood industrial networks, and a method of drying peeled veneer in roller dryers with steam wallpaper at an agent drying temperature of 13D-140 C, the purpose of the invention is to accelerate the drying process with high quality dried veneer. This is achieved by the fact that the raw veneer is pre-passed through the pseudo-spinal layer of fine-grained inert material at a temperature of 250-270 C. Its moisture content is up to 20-25%, and then exhaled in a dense foot for 2-3 hours. Example. Birch sheet veneer sheets with a thickness of 1.5, with a starting density of 80, are placed in a pseudo-spinal layer of an inert fine-grained material at a temperature of 260 ° C for 0.3 minutes. After that, sheets of veneer venhnostdo 0 are placed in tight feet for straightening and a bath of moisture on the area of sheets. The exposure time in the feet is 2-3 hours. After keeping in dense feet, veneer sheets are passed through a roller dryer with parsvoy heating at a temperature of 130 C. For 5 min, veneer sheets are dried to a moisture content of 6%. SUBJECT OF THE INVENTION A method of drying peeled ypon in a roller dryer with steam heating at a drying agent temperature of 130-140 ° C, from the h and D a and so that, in order to accelerate the drying process with high quality veneer being dried, the latter is previously placed in the pseudohischeny layer of fine-grained inert material at a temperature of 250-270 C, dried to a viscosity of 20-25%, then vydervayut in dense feet for 2-3 hours.
