The new type of filtration washing and drying machine has a cylindrical cone structure, with heating jackets installed on the cylindrical body and lower cone to heat or cool the material. The multifunctional machine is equipped with a hollow shaft and a variable angle and variable lead hollow spiral stirring device to stir and lift the material, and push it out during discharge. A conical filtering device with a complex structure is installed inside the lower cone, and there is a specially designed blind spot quick discharge device or blind spot pneumatic discharge ball valve at the bottom of the equipment.

In the reaction stage, the reaction material is added from the beginning, and the unique stirring structure allows the material to be uniformly stirred inside the machine, and heated or cooled simultaneously through the cylinder jacket, cone jacket, hollow shaft, and hollow spiral blade, allowing the material to fully react inside the machine. In the filtration stage, this machine can filter and dry the material through pressure or vacuum filtration inside the machine, and add washing solution to automatically re slurry and wash the material multiple times inside the machine. After meeting the washing requirements, it can be compressed and dried again. In the drying stage, the cylinder jacket, cone jacket, hollow shaft, and hollow screw simultaneously heat and vacuum the material, and perform vacuum sealed low-temperature drying on the material. After drying, the material is automatically sealed and discharged.

At present, China's chemical industry uses equipment such as centrifuges, plate and frame filters, and vacuum filters to filter and separate materials. Most of these devices have single functions, high labor intensity, and significant material loss during operation. What is more noteworthy is that these devices are generally operated in an open manner, which can easily cause pollution to the environment and harm the health of operators. There are also some problems with the use of drying equipment, particularly the incomplete recovery of solvents and insufficient dust collection devices. Some production enterprises adopt open-air drying methods, which are not conducive to the economy or the environment, affecting product quality and must be improved as soon as possible.

(1) One machine is versatile and can complete various operations such as reaction, extraction, filtration, repeated filtration and washing, drying, etc. in one machine, and directly obtain finished products.

(2) Sealed operation is particularly suitable for handling flammable, explosive, toxic, or highly toxic dangerous products, as well as fresh food, biological products, and drugs that are not allowed to be contaminated.

(3) The cylinder jacket, cone jacket, hollow shaft, and hollow screw simultaneously heat or cool the material, with high thermal efficiency and low energy consumption.

(4) The special stirring spiral design enables uniform stirring of materials at all stages of reaction, filtration, washing, and drying, resulting in high overall efficiency of the machine.

(5) In the filtration stage, due to the good adhesion and scraping effect between the screw belt and the filter medium, the material can be filtered under the condition of thin layer filter cake, resulting in high filtration efficiency.

(6) Simplify and shorten the process flow, occupy a small area, and greatly save investment in factory buildings and equipment.

(7) Easy to operate, low labor intensity, and high-quality processed products.

The filtration washing and drying machine is widely used in the fields of pharmaceuticals, food, pesticides, chemical engineering, etc. In response to some defects found in the long-term production and use of the flat three in one, a multifunctional cylinder cone filtration washing and drying machine has been successfully developed to achieve continuous fully enclosed processes such as material filtration, washing, drying, sterilization, and unloading. From structural design to application, it closely follows the corresponding regulatory requirements of the pharmaceutical industry and has been maturely applied in many pharmaceutical companies.

The conical three in one dryer is a drying equipment that integrates drying, cooling, and screening functions, mainly used for drying and processing powdered or granular materials. This device is widely used in industries such as chemical, food, pharmaceutical, and feed due to its compact structure, easy operation, energy efficiency, and other characteristics.
