In many industries such as chemical, pharmaceutical, and food, the post-treatment processes of materials such as filtration, washing, and drying have a crucial impact on product quality and production efficiency. The traditional production method often requires multiple unit devices to operate separately, which not only makes the process cumbersome and the equipment occupies a large area, but also easily leads to problems such as material leakage and environmental pollution. Wuxi Shuangrui Machinery Co., Ltd., with its profound technical accumulation and innovative spirit, has developed a fully enclosed four in one washing and drying machine, bringing a new and efficient solution to these industries.
1、 Working principle and process of fully enclosed four in one washing and drying machine
Wuxi Shuangrui Machinery's fully enclosed four in one washing and drying machine ingeniously integrates the functions of crystallization, filtration, washing, and drying. In the crystallization stage, the reaction material is added to the equipment from the top, and through the stirring structure, the material can be thoroughly and uniformly stirred inside the equipment. At the same time, the cylinder jacket, cone jacket, hollow shaft, and hollow spiral blade can simultaneously heat or cool the material, promoting the material to fully react and complete the crystallization process inside the equipment.
Entering the filtration stage, the material is filtered and dried inside the equipment through pressurization or vacuuming. According to different material characteristics and process requirements, the filtration or pressure filtration mode can be flexibly selected, and the filtrate is smoothly discharged from the bottom branch pipe. During this process, some equipment is also equipped with nitrogen back blowing and bubbling technology to further improve the filtration effect. After the filtration is completed, open the bottom pipe and quickly open the sealing plate to ensure that the residual liquid is completely drained.
The washing process is also completed inside the equipment. Inject an appropriate amount of cleaning solution from the central tube, start the stirring device, and mix the filter cake and cleaning solution thoroughly to achieve thorough washing of the filter cake. Through multiple automatic re slurry washes, impurities in the material can be effectively removed to achieve ideal washing requirements, and then the material can be dried again.
The final stage is the drying stage, during which the cylinder jacket, cone jacket, hollow shaft, and hollow screw simultaneously heat the material, evacuate the top, and create a vacuum sealed low-temperature environment for efficient drying of the material. After drying is completed, the material is automatically sealed and discharged in one go, greatly reducing the number of material transfers and lowering the risk of material contamination.
2、 Core Structure and Innovative Design
1. Excellent mixing system: The equipment adopts advanced mixing structures inside, such as S-shaped impellers or variable angle and variable pitch hollow spiral mixing devices. These stirring devices can not only accelerate the cooling and crystallization of materials during the crystallization process, making the cooling of materials more uniform and effectively shortening the cooling time; In the drying stage, it can also ensure that the material fully contacts and exchanges heat with the cavity wall during the flipping process, avoiding local overheating or uneven heating of the material, and improving the drying efficiency and quality. In addition, the cavity inside the stirring blade can be connected to the heating medium through the rotating joint at the shaft end, further enhancing the heating effect on the material.
2. Efficient filtration device: The fully enclosed four in one washing and drying machine is equipped with a high-precision filtration system, such as flat plate sintered mesh filtration or conical filter media. Among them, the effective filtration area of the conical filter medium is significantly increased compared to the flat bottomed equipment of the same diameter, up to three times as much, significantly improving the filtration efficiency. At the same time, the rated thickness of the filter cake is small, and the screw belt stirring mechanism continuously replaces the filter cake, so that the filter cake is always subjected to a stable pressure difference during the filtration process, which can obtain a filter cake with lower moisture content, laying a good foundation for subsequent washing and drying processes.
3. Flexible and diverse heating methods: This device provides multiple heating methods, including half tube or jacket heating of the cylinder, heating device inside the chassis, and hollow blade heating connected through shaft end rotating joints. These heating structures can be combined and used according to actual process requirements, or operated separately to provide precise temperature control for the reaction, crystallization, and drying of materials, meeting the strict requirements of different materials for heating conditions.
4. Fully enclosed and online cleaning and sterilization design: In order to meet the high requirements for hygiene and safety in industries such as medicine and food, the equipment adopts a fully enclosed design, effectively preventing materials from coming into contact with the outside air, avoiding problems such as material oxidation, moisture absorption, and microbial contamination. At the same time, the equipment is equipped with advanced online cleaning (CIP) and online sterilization (SIP) systems, which can automatically complete cleaning and sterilization functions by installing spray balls, connecting pure steam, and adding cleaning solvents without disassembling the equipment, ensuring that the interior of the equipment always maintains a sterile state and complies with relevant standards and specifications such as GMP.
5. Intelligent control system: The fully enclosed four in one washing and drying machine is equipped with an advanced intelligent control system, using PLC controller and touch screen operation interface, which can accurately set and monitor various operating parameters of the equipment in real time. Operators can clearly see the operating status, temperature, pressure, vacuum degree and other parameters of the equipment on the operation interface, and can flexibly adjust them according to actual production needs. The system also has data recording and storage functions, which facilitate traceability and analysis of the production process, further improving the intelligence level of production management.
In short, Wuxi Shuangrui Machinery's fully enclosed four in one washing and drying machine has brought revolutionary changes to the production of many industries with its innovative design concept, excellent performance advantages, and wide application fields. With the continuous advancement and innovation of technology, we believe that this equipment will play a more important role in future industrial production, helping enterprises achieve sustainable development goals of efficiency, environmental protection, and safety.
