Second, the company is strong in technology, equipment technology, debugging and drug production debugging experience The product by the experienced engineers to be responsible for the design and technical responsibility, and is very familiar with the pharmaceutical production, design in the full consideration of the requirements of the production process such as Heat transfer, mass transfer, mixing, drying, sterilization, spraying and other mechanisms, in the structure to take appropriate measures to meet the pressure, temperature, medium, corrosion, sealing, safety, interlock and fault system, Pharmaceutical production requirements. Filtration, washing and drying equipment has long been restricting the development of China's pharmaceutical industry, the domestic strength of the manufacturers are imported Switzerland, Germany, France, Italy and other foreign equipment, but due to equipment technology, equipment failure, maintenance is not in place and expensive spare parts All the reasons, resulting in the production is not normal or downtime, are now invited to help companies to analyze and solve. So it is a great understanding of the shortcomings of foreign models in the design of the company's models of improvement and innovation are very helpful, making the company's products in the structure and technology than other companies more advantages.

Third, stirring the structure and performance of the blade filter, washing and drying equipment, the principle of operation, the main process for the mixing, washing, flat material, filtration, drying and discharge. These functions and performance are closely related to the working conditions of the paddle blades, so the design and manufacture of the blade is the core technology of the machine. The company has a variety of blade fluid working state experimental means and consider a variety of different drug specific gravity, viscosity, wet weight on the mixing blade, spindle, motor, reducer, rack and other aspects of the impact of optimization equipment. So the equipment in more than five years, in the use of manufacturers in the production process than the reliability and effectiveness of foreign models to be stronger, such as the German model stirring blade effect is poor, put on the company double S-type strong heat transfer paddle Leaves, the effect of prominent.

Fourth, the vertical tank is both a closed container, but also a variety of parts and components installed, in addition to its sufficient strength and stiffness, the processing accuracy requirements are also high. Tank (different diameter) from the thickness of 14 ~ ~ 20mm SS316L (or SS304) by the rolling plastic processing, the outer wall of the use of foreign advanced heating structure of the honeycomb sandwich, the heating area, heat transfer effect than ordinary Single-layer jacket and half-tube structure sandwich better. Compared with the specifications of foreign equipment, heating up, the temperature along the wall evenly. According to the user to reflect, in increasing the production capacity, the drying time does not increase, the effect is good.

Fifth, the tank after welding, the tank body wall, chassis sealing surface, the upper and lower end of the overall machining. The company has the tank diameter of up to 3200mm, the processing depth of 2100mm machining capacity (maximum production of 9m2 equipment), such a large diameter and bulky parts, must be large vertical machine tools for processing, the processing of difficult. Its structural design and machining accuracy directly affect the quality of the machine, which is currently no domestic manufacturers to do. So the domestic manufacturers often appear different from the tank and the tank heart, stirring paddle wall, the machine is not vertical sealing caused by failure and other issues, which are related to the tank processing methods and technology, which is one of the quality advantages of the Company.

Six, the main mixing shaft seal structure The company has three mechanical seals and a double packing box sealed structure, according to different production process requirements to choose the appropriate one: mechanical seal structure:

1, dry double-sided mechanical seal (sterile, with bellows protection)

2, wet double-ended mechanical seal (sterile, with bellows protection)

3, dry double-sided mechanical seal (industrial, no bellows protection) spindle seal is to prevent the outside air and particles into the tank to ensure that the tank is not contaminated, while preventing flammable and explosive gas leakage caused by production safety threats, Ensure that the drug meets key requirements for GMP requirements.

The company's mechanical seal design using a special structure, its characteristics are:

1, machine sealing, static ring with a special material to match, more commonly used than SiC SiC more durable.

2, the machine has a media cavity, can be online cleaning, sterilization, disinfection, in the case of spindle heating can be cold nitrogen cooling, to prevent uneven temperature and adverse effects, so that reliable operation.

3, machine seal According to the use of different requirements, the spindle and the blade connection with the upper and lower telescopic multi-layer bellows (sterile and oral type), and a no bellows and can be up and down the spindle structure (industrial).

4, the company's industrial double-packing box spindle seal, which is characterized by: double-layered PTFE filler by the screw fastening and a spring to prevent the filler after the leak, in the two packing box between the other nitrogen gas sealed cavity, To prevent flammable and explosive gas leakage, the sealing pressure higher than the tank. This sealing structure has a unique advantage, unlike the general stuffing box, which is the company's technical advantages.

Seven, the discharge valve is sterile and industrial two kinds of the company's valve is the company's patent, the valve with hydraulic cylinder to open, close and safety interlock, complex structure design, manufacturing high precision, especially on the (SS316L, SS304, Hastelloy-22 Titanium Alloy, etc.) are selected according to the different materials. Seat and spool for the metal to metal wire seal (also known as hard seal), can also be used soft seal. Hard seal welding special alloy, improve the sealing performance and extend the sealing life, the valve body without dead ends easy to clean, through the special hinge can open the spool for cleaning and disinfection, the use of polytetrafluoroethylene bellows will be isolated from the sterile cavity , Will not contaminate the drug. The valve body and the tank can be connected after the steam sterilization, in line with GMP requirements.
