Laboratory Three-in-one dryer (Cylindrical cone type)

The laboratory filtration, washing and drying integrated machine adopts a cylindrical and conical structure. Heating jackets are set on the cylindrical body and the lower cone, which can heat or cool the materials. Inside the multi-functional machine, there are hollow shafts and variable-angle and variable-lead hollow spiral stirring devices for stirring and lifting the materials. When discharging, the materials are pushed out. A relatively complex conical filtering device is set in the lower cone. At the bottom of the equipment, there is a specially designed quick discharge device without dead corners or a pneumatic discharge ball valve without dead corners.

During the reaction stage, the reaction materials are added from the top. The unique stirring structure enables the materials to be evenly stirred inside the machine. Through the simultaneous heating or cooling of the cylinder jacket, conical jacket, hollow shaft and hollow spiral blades, the materials can be fully reacted inside the machine. During the filtration stage, this machine can make the material dry through pressure or vacuum filtration inside the machine, and add washing liquid to make the material undergo multiple automatic re-slurry washing inside the machine. After meeting the washing requirements, it can be pressed dry again. During the drying stage, the cylinder jacket, conical jacket, hollow shaft and hollow screw ribbon simultaneously heat the material and create a vacuum at the top to conduct vacuum sealed low-temperature drying of the material. After drying, the material is automatically sealed and discharged.

Performance features of the three-in-one laboratory dryer

(1) Multi-functional in one machine, it can complete various operations such as reaction, extraction, filtration, repeated filtration and washing, and drying within one machine, and directly obtain the finished product.

(2) It has a large operational flexibility and can adjust the operation cycle by regulating the filtration pressure difference, rotational speed, and screw extrusion lead, etc., to adapt to changes in process conditions.

(3) This machine can form a very thin filter cake on the surface of the filter medium or perform filtration without a filter cake. The filtration rate per unit filtration area is very high, so the equipment is small and compact.

(4) Fully enclosed system, with an excellent operating environment, is particularly suitable for handling toxic, flammable, explosive and other dangerous products, as well as fresh and delicious foods, biological products and medicines that are not allowed to be contaminated.

(5) It can both concentrate and filter. Especially when it is necessary to wash the materials, the materials can be concentrated first and then thoroughly washed in a suspended state. Finally, they can be pressed and filtered. This can reduce the handling of materials, minimize waste, and there is no need for slurry during washing, resulting in very high product quality.

(6) It can be used for three operations: reaction, filtration and drying, enabling the functions of the three unit devices to be accomplished on this single device. As a result, the equipment cost, floor space, labor intensity and energy consumption are all significantly reduced.

(7) This machine has low power consumption. The moisture content of the filter cake it extrudes is generally lower than that of the three-in-one plate type, and it is also convenient to operate.
