Vrieco-Nauta錐形（xíng）真空幹燥機
描述
熱能基本上是轉移（yí）到產品（pǐn）中，通過的夾套容器壁導致（zhì）溶劑或水分殘留蒸發。軌道沿容器壁的旋轉螺杆和有助於蒸汽（qì）逃逸到表麵上，在同一時間（jiān）提供與加熱表麵（miàn）接觸的顆粒在一（yī）個頻繁（fán）交換。
真空係統中的容器保持恒定的（de）真空下，並刪除從容器的蒸氣。幹燥（zào）器上麵安（ān）裝的過濾器中分離（lí）夾帶的（de）灰塵顆粒。

Vrieco-Nauta Conical Vacuum Dryer
Description
Heat energy is basically transferred into the product through a jacketed vessel wall causing solvents or moisture residues to evaporate. A rotating screw orbits along the vessel wall and helps the vapours to escape to the surface, at the same time providing a frequent exchange of particles in contact with the heated surface.
A Vacuum system keeps the vessel under constant vacuum and removes vapours from the vessel. Entrained dust particles are separated in a filter mounted above the dryer.

Features / Benefits
Fast drying times as the mixing screw continuously circulates the product from the bottom to the top of the vessel improving heat transfer conditions.
Final moisture after drying is possible down to 0%.
Low energy consumption.
Gentle to product.
Quick and efficient removal of vapours.
Recovery of pure solvents is possible.
Dried solids are suitable for direct use.
Easy to clean.

Applications
Particularly suitable for final drying of powders, granules, pastes and slurries especially when they are brittle and/or temperature sensitive.
