Principle and application prospect on wood drying of displacement drying;

Before it was calcined to produce nanoscale magnesium oxide, the precipitate was dried to remove its solvent by the following methods: direct drying, displacement drying and surface modification drying.

One of the nonthermal methods of drying and dewatering is displacement drying where solvent is used to "displace" liquid moisture from the wet material.

Zirconium oxide with a particle size of about 20-50 nm was prepared using the replacing solvent drying technique, and was characterized using XRD and TEM.

Performance Evaluation of a Solar Grain Dryer;

Based on the "solar plum drying project" , we studied the drying characteristics of flowers in laboratory , then designed and developed a solar dryer and field experimented aiming at the special material—fresh flowers.

According to the characters of drying requirement of kinds o f wood,the timber drying equipments have been researched and designed to satisfy the timber drying demands of various trees and sizes.

The solar energy-wet removal machine combined drying apparatusconsists of the solar energy heat-collecting system, wet removal machine, dryinghouse and control apparatus and is the drying apparatus operated by combiningnew energy equipment with energy-saving equipment.
