As we all know, reaction, filtration, and drying are three very important unit operations in the chemical, pharmaceutical, and food industries. Generally, three units of equipment: reactor, filter, and dryer are required to complete. Each of the three unit equipment has its own supporting device. Because of the large area and high cost, the handling or transportation of materials between the units is more troublesome. Not only is labor intensive, but also easy to cause material loss and waste. Inflammable, explosive, toxic or highly toxic materials or non-contaminated biological products, medicines, foods, etc., require airtight operation. At this time, it is more difficult to transport materials between the three devices of reaction, filtration and drying. Sometimes As a result, the whole set of equipment is often unable to operate normally or has high labor intensity, long production cycle, high energy consumption, and low efficiency, which affect product quality.
It is for the above reasons that Wuxi Shuangrui Machinery Co., Ltd. has carried out a lot of design and research and development work, and finally successfully developed the SR-cylinder-cone reaction filtration and drying multifunctional machine. The invention patent number: ZL2017 2 1560677.6. This invention has been realized as a major breakthrough in chemical and biological pharmaceutical equipment technology.
Patented Equipment Vertical Conical Vacuum Dryer（3-in-one）Working Principle
The new cylinder cone filtering, washing and drying three-in-one equipment is a cylinder cone structure. A heating jacket is set on the cylinder and the lower cone to heat or cool the material. A hollow shaft and a transformer are arranged inside the multifunctional machine. The angle-variable lead hollow spiral stirring device stirs, stirs and lifts the material, and pushes the material out when it is discharged. A conical filter device with a more complicated structure is arranged in the lower cone, and a specially designed quick-opening discharge device without dead angle or a pneumatic discharge ball valve without dead angle is arranged at the bottom of the equipment.
In the reaction stage, the reaction material is added from the top. The unique stirring structure can make the material get uniform stirring in the machine, and it can be heated or cooled through the barrel jacket, cone jacket, hollow shaft and hollow spiral blade at the same time. Make the material fully react in the machine. In the filtering stage, the machine can make the material in the machine filter dry by pressurizing or vacuuming, and add washing liquid, so that the material can be automatically repulped and washed in the machine for many times, and then pressed dry after reaching the washing requirements. In the drying stage, the barrel jacket, cone jacket, hollow shaft, and hollow spiral belt heat the materials at the same time and draw a vacuum on the top, and vacuum-sealed the materials for low-temperature drying. After drying, the materials are automatically sealed and discharged.
Patented Equipment Vertical Conical Vacuum Dryer（3-in-one）Process flow
1. Stirring reaction: This machine has a barrel-cone structure, and can be used to heat or cool materials in the machine for constant temperature and timing reaction;
2. Pressure filtration or vacuum filtration: After the reaction, the filtrate is filtered through pressure filtration or vacuum suction. In the filtration stage, due to the good adhesion of the ribbon and the filter medium, the material can be placed in the thin layer of the filter cake. Filter under conditions, with high filtering efficiency;
3. It can be washed and filtered multiple times: After filtering and drying the material, you can add the washing liquid, and perform multiple automatic reaction and mixing with the material in the machine before washing. After the washing and filtering meet the washing requirements, it can be filtered and dried.
4.Vacuum drying and discharging: After the material is filtered and dried, the barrel jacket, hollow shaft and spiral belt are heated at the same time in the drying section, and the material is vacuum-sealed and dried at low temperature by vacuum at the top. After drying, the material is automatically sealed Discharge.

Patented Equipment Vertical Conical Vacuum Dryer Technical （3-in-one）Performance characteristics
1. One machine with multiple functions, can complete various operations such as reaction, extraction, filtration, repeated filtration, washing, and drying in one machine, and directly obtain the finished product.
2. Airtight operation, especially suitable for handling flammable, explosive, toxic or highly toxic dangerous products and fresh food, biological products and medicines that are not allowed to be contaminated.
3. Cylinder jacket, cone jacket, hollow shaft and hollow spiral belt can heat or cool materials at the same time, with high thermal efficiency and low energy consumption.
4. The special mixing screw design can make the materials uniformly agitate the materials in the various stages of reaction, filtration, washing and drying, so that the working efficiency of the whole machine is very high.
5. In the filtering stage, due to the good adhesion and scraping effect of the spiral belt and the filter medium, the material can be filtered under the condition of a thin layer of filter cake, with high filtering efficiency.
6. Simplify and shorten the process flow, occupy a small area, and greatly save plant and equipment investment.
7. Convenient operation, low labor intensity, and good quality of processed products.
