Stainless steel double cone vacuum dryer

Description

Double cone vacuum dryer（RCVD） also named conical dryer blender (CDB) is a kind of multi-functional machine of mixing & vacuum drying, it is a batch type fully closed process equipment for solid-liquid separation, vacuum drying of powder & granular solid and low -temperature concentrating of reaction solution, which is widely used in chemical industry, fine chemical industry, foodstuffs industry and pharmaceutical process industry. The excellent corrosion resistance, anti-stick and cleanliness of the glass-lined vessel is especially suitable applicating for material that easy to be oxidized, volatilized, heat sensitive & toxic, not permitted to destroy its crystal in drying process, and the solution should tobe recovering.

Model/Code/Type 304, 316L are chromium-nickel austenitic alloys that common use stainless steel material for SST RCVD/CDB. And polishing finish with mirror inner surface and matte treatment for outer surface special apply in clean production.

WORKING PRINCIPLE

After the wet materials are feed into the vessel of RCVD/CDB, close all the valves and lips on the vessel and then start the vacuum pump; heating the vessel body by jacket pass though the heating media(hot water /steam/ thermal oil); the heat is in contact with the wet material through the inner wall of the vessel body,moisture is evaporated from the wet material, then the vapor is pumped out by the vacuum pump through the vacuum exhaust pipe; since the vessel is in a vacuum and rotating state to make the material constantly turn up and down inside and outside, so speed up the drying speed of the wet material, improve the drying efficiency, and achieve the purpose of uniform drying of the material.

PROPERTY OF COMMON USE SST MATERIAL

Stainless steel  is a group of ferrous alloys that prevents the iron from rusting. Stainless steel's resistance to rusting results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack.

CAUTION

Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary mild steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry.

EFFECTED FACTORS OF RCVD/CDB OPERATION

◆Material Characteristics: Viscosity of material, allowable temperature of material, bulk density of materials, slip angle of material;

◆Heating Temperature & Drying Speed: Heating temperature & Drying speed;

◆Working Pressure of Vessel;

◆Swing Speed of Vessel.
