A questionnaire related to the wood drying was carried out among wood processing enterprises in Latvia to clarify the main problems and possible differences depending on production capacity and products. Deformation (twist, bow, spring, cupping etc.) during the kiln drying has been identified as the most important problem for all enterprises. Many problems are related to the product area as very often improper drying technology or incorrect drying schedule is used. Others are connected to the organization and control of drying process - optimisation of the drying schedule, energy consumption, kiln control unit, maintenance of measuring equipment, MC measurement, quality control during drying. There is a difference between softwood and hardwood drying in the product and sales area. Considerably more problems are recognized in hardwood drying (hardwood is often used in furniture production and has higher quality demands).
