Feature of product: 
Transmission parts Yuntai ZB type rake Vacuum Dryer using stable, durable cylindrical gear reducer, drive shaft using a bold solid stainless steel shaft, rake made of high strength cast stainless steel rake, rake Vacuum Dryer fully guaranteed in a variety of harsh stable operation of the working environment. Optional heating medium steam, thermal oil, hot water. Apply loose powder and granular material drying. 
ZB type rake Vacuum Dryer Vacuum Dryer is tapping rod for improved adaptation produced machine type in ordinary rake Vacuum Dryer basis. Casing can be added to two or four percussion stick, in order to facilitate rapid drying and pulverizing the material. Optional heating medium steam, thermal oil, hot water. Suitable for easy adhesion reunion before drying, after drying loose material. 
ZB type rake Vacuum Dryer's paddle rake Vacuum Dryer ordinary rake Vacuum Dryer binding paddle drier heat transfer area, the characteristics of fast drying rate, appropriately modified to produce the machine type. In addition to all ordinary rake drier specific advantages, since the built-in hollow paddle, mixing ribbon, rake drier than normal have a stronger Drying capacity, dry strength doubled, discharge speed. Optional heating medium steam, thermal oil, hot water. For high solvent content that requires quick drying simultaneously mixed charge; for solvent-containing material has obvious advantages. 
ZB type rake Vacuum Dryer Double ribbon rake Vacuum Dryer is adaptive for improved machine type produced by ordinary rake Vacuum Dryer basis. In addition to all ordinary rake drier specific advantages, since the built-in positive and negative double ribbon forced continuous turning, mixing, drying of the material during difficult reunion, caking, applies to those easy to join, agglomeration of loose material vacuum drying. Also as mixer apply. Optional heating medium steam, thermal oil, hot water. Apply loose powder granular materials synchronization is complete drying and blending. 
ZB type arm rake Vacuum Dryer is adaptive for improved machine type produced by ordinary rake Vacuum Dryer basis. Top device can quickly fully open, so that the material discharge speed and cleaning no dead ends to create clear conditions. Optional heating medium steam, thermal oil, hot water. It applies to poor mobility, drier variety of materials using the same equipment.

Product Brief: 
ZB type rake Vacuum Dryer rake leaves by means of the central axis, the timing interval reverse rotation, the material is rotated to move forward with the rake leaves on both sides, and with the reverse rotation center remitted by both sides. Since in rake leaves, stirring constantly, when the material and the cylinder wall contact surfaces constantly updated, and is indirectly heated by steam, the inner parts of the wet material continuously vaporized while being vacuum pump promptly withdrawn. Given the high degree of operating vacuum 400-700mmHg, wet parts of lower boiling point, the vapor pressure of the material surface of the wet parts of the machine is much larger than the wet parts of the vapor space of the vapor pressure, beneficial to its internal parts wet evaporation, promotes drying, so as to achieve the purpose of drying. Depending on the product properties and requirements, after a certain drying time, drying the finished product from the lower portion of the cylinder quick opening discharge, typically up to a moisture content of 0.1% to 0.05% (wet). 
Part of ZB type rake Vacuum Dryer mainly by the stirring shaft, cylinder, transmission and sealing devices. The heat required for drying is mainly provided by the agitator shaft and the cylinder jacket. When the heating medium through the device, the heat through the jacket and the agitator shaft on the material is indirectly heated, the moisture in the wet material is heated to vaporize the vaporization of moisture is pumped vacuum system in a timely manner. With the continuous rotation of the agitator shaft, the contact material with the heated surface constantly updated, so that the material evenly heated, so as to achieve good drying effect.

working principle: 
ZB type rake Vacuum Dryer is the use of the material in the water in a vacuum state to reduce the boiling point of the characteristics of drying equipment. ZB type rake Vacuum Dryer indirect heating steam jacket, water evaporation and heat extraction in time. In the drier casing, rake end axis design has a certain angle. Spindle reverse rotation by the forward axial movement of the material in order to facilitate drying and discharging.

Product Features: 
ZB type rake Vacuum Dryer jacket and inner stirring at the same time using the heating mode, heat transfer surface large, high thermal efficiency. 
ZB type rake Vacuum Dryer set stirring, the material in the barrel to form a continuous cycle of state, to further improve the uniformity of the material heated. 
ZB type rake Vacuum Dryer set stirring, allowing smooth paste, paste, paste material drying. 
ZB type rake Vacuum Dryer system horizontal intermittent conduction Drying equipment, for oxidation, easily broken, heat-sensitive type granular powder, paste, paste material drying process, such as Pigment, fuel and intermediates, plastics, resins, inorganic salts, and clay and other drugs.

Product advantages: 
1, uniform drying, to avoid oxidation, overheating, low moisture content of the product obtained, the product does not need to smash particles less demanding material to packaging. 
2, high ZB type rake Vacuum Dryer evaporation intensity, generally evaporate 10-15㎏ (water) / m · h. 
3, ZB type rake Vacuum Dryer no air intervention, condenser load is small, the solvent can be easily recovered materials. 
4, solvent vapor entrainment after the bag filter and no environmental pollution. 
5, ZB type rake Vacuum Dryer small amount of steam, because the vacuum rake drier and more steam through the jacket, the use of steam for heating material, Handled amount of steam consumption per kilogram of finished product is small, typically 1.3 to 1.5㎏ steam. 
6, ZB type rake Vacuum Dryer outlet valve in the cylinder body ball valve without dead ends, easy unloading. 
7, the heat medium can be water vapor, thermal oil, hot water or boiler flue gas. 
8, vacuum rake drier simple, low capacity, low labor intensity. 
9, little material to escape, reducing costs while also improving the environment.
