The working principle and equipment characteristics of the three-in-one vacuum dryer

Three-in-one vacuum dryer, conical filter washing and drying equipment overview
The drying machine integrating vacuum filtration, washing and drying functions is designed and manufactured by absorbing the advanced technology, principle and characteristics of foreign "three-in-one" equipment, and combining with domestic actual conditions. It can replace filtering and drying equipment at the same time, and complete the whole process of filtering, washing, drying and solid unloading in the same equipment.

The three-in-one vacuum dryer can be widely used in pharmaceutical, chemical, pesticide, food and other industries, and is the best equipment for filtering and drying.

It can realize the continuous operation and production of fully enclosed and whole process, and is more suitable for the production of products with sterile requirements and toxic products. It is a complete set of domestic equipment, the overall design is more compact, the structure design is simple and reasonable, and it can completely replace the imported "three-in-one" equipment.

Three-in-one vacuum dryer, conical filter washing and drying machine working principle
The machine is designed as a double-cone tank body, one end is a filter plate, and the other end is a washing and discharge port. Steam or hot water can be passed into the jacket to heat the inner tank.

The tank body is placed on the racks on both sides through the main shaft. One of the two ends of the main shaft is the steam and condensed water interface, and the steam is passed through to complete the heating process, and the other end is the vacuum port, through the vacuum pump or vacuum system, the tank is in a vacuum state, the suction filtration process is completed, and it is pumped away during the drying process. evaporated water vapor. The motor or reducer is also placed in the frame, and through gear transmission, it drives the tank body to rotate forward and backward, so that the material is continuously turned up and down, inside and outside.

During the washing process, the materials can be fully and evenly mixed, and the washing process can be completely completed. During the drying process, the heating surface can be replaced continuously to make the material heated evenly and achieve the purpose of balanced drying. The new filter washing and drying machine has a barrel-cone structure. There are heating jackets on the cylinder body and the lower cone body to heat or cool the materials. There are hollow shafts and variable-angle variable-lead hollow shafts inside the multi-function machine. The spiral stirring device stirs, stirs and lifts the material, and pushes out the material when discharging.

A conical filtering device with a relatively complex structure is installed in the lower cone, and a specially designed non-dead angle quick-opening discharge device or a non-dead angle pneumatic discharge ball valve is installed at the bottom of the equipment.
In the reaction stage, the reaction materials are added from the top, and the unique stirring structure can make the materials be stirred evenly in the machine, and the materials are heated or cooled simultaneously through the cylinder jacket, cone jacket, hollow shaft, and hollow spiral blade. Make the material fully react in the machine. In the filtration stage, the machine can filter and dry the material in the machine by pressurizing or vacuuming, and add washing liquid, so that the material can be automatically repulped and washed several times in the machine, and then pressed dry after meeting the washing requirements.

In the drying stage, the cylinder jacket, cone jacket, hollow shaft, and hollow ribbon heat the material at the same time and vacuumize the top, vacuum-tight and low-temperature drying of the material, and automatically seal and discharge the material after drying.

Three-in-one vacuum dryer, conical filter washing and drying machine Features
1. The integrated design simplifies the process, reduces the loss and improves the product yield.
2. Each sealing point is equipped with double seals, and the sealing material is silicone rubber or fluororubber.


3. The filter material is filter cloth, stainless steel wire mesh sintered or powder sintered plate, metal sintered plate.
4. The chassis is detachable, and the upper and lower flanges are clamped with quick-installed bolts to achieve a sealing effect. The chassis is disassembled with a cylinder or dropped to the ground, and pulled out to clean the filter plate.


5. The tank body can be turned forward and reverse, and the speed can be adjusted arbitrarily between 1 and 10 rpm through the control of the frequency converter. The main rotation includes an automatic brake device.
6. Set cleaning in place, sampling in place and steam disinfection. Prevent product contamination and better meet GMP requirements.


7. Operate in a closed state, the product has no leakage, no pollution, and is suitable for materials with strong irritating odor and toxicity.
8. Operate under vacuum, and have a high evaporation rate at low temperature, especially suitable for drying heat-sensitive materials and easily oxidized materials, and also suitable for materials containing solvents, and can recover solvents.
9. The equipment has compact structure, small footprint and easy operation.


10. The loading capacity is large, and the loading coefficient can reach 30% to 40%.
