Product details
1、 Overview
The 'Single Cone Spiral Vacuum Drying Machine' is a widely used vacuum drying equipment in pharmaceutical production in European and American countries. Manufacturers with years of experience in raw material production know the technical advantages of the 'Single Cone Spiral Vacuum Drying Machine', such as optimized mixing system, heating efficiency of dried materials, high-quality and accurately manufactured components, precision of minimum distance between spiral mixing and cylinder wall, reliable and sturdy design, and minimal maintenance. This type of equipment is still blank in China, and the successful development of this drying equipment has greatly improved the equipment level of the domestic medical and chemical industry production.
2、 Typical process of vacuum drying mixing
The working process of the single cone spiral vacuum dryer is batch operation. After the wet material enters the silo, it is dried using a jacket, stirring and heating. By selecting a suitable single cone vacuum dryer (working volume), the required processing capacity range can be achieved. The mixer and mixing screw with an upper drive structure can be disassembled and assembled in sections. Due to the ample installation space, it is suitable for use and maintenance in GMP workshops. At the same time, the single cone spiral vacuum dryer has an efficient drying and mixing capacity 3-4 times that of the double cone vacuum dryer. The material loading rate can work normally at 10% -100%. The cantilever screw mixing can achieve high mixing accuracy. Even under harsh conditions such as adding a small amount of material to a large amount of material, it can be mixed evenly in the dryer. With its unique mild mixing characteristics, even products sensitive to drying processing will not be damaged, and the required driving power is relatively low. The high vacuum design of this dryer has significant advantages for temperature sensitive products, with good thermal conductivity, fast drying, and low energy consumption. The filter directly connected to the dryer can retain dust particles in the processing area. The machine adopts an inflatable sealed hemispherical valve for thorough and convenient unloading, excellent vacuum and pressure sealing performance, no dead corners, easy to clean design, stable performance, and long service life, ensuring that you can continue processing products without any loss. This multi-purpose drying/mixing equipment is the ideal equipment to meet your production needs.
3、 Characteristics:
The fully cantilevered conical stirring spiral shaft fully enclosed system product has soft stirring and good circulation. It uses multiple materials and technologies to achieve safe and reliable sealing. The mechanical shear force is low, the drying time is short, the energy consumption is low, the accuracy is high, the stirring effect is good, the renewability is strong, and there is no pollution gas leakage. It is suitable for the production of various process products. It has a wide range of uses. The speed can be flexibly divided according to the product characteristics (10-100%), and it has no impact on product quality. The use of heated stirring spiral shaft can shorten the drying time. The solid discharge and cleaning liquid discharge have no residue to ensure the safety of the product, operator and production process. The online cleaning is efficient and simple, and the discharge is thorough. It can be flexibly used
4、 Scope of application
1. Products with fluidity: dangerous substances such as powders, particles, crystals, etc
2. Products sensitive to mechanical processing and high temperatures
3. Flammable materials and explosive powders
4. Products that are easily decomposed under oxidation
5. Products contaminated with flammable solutions
5、 Main structure
1. Blender: It is driven by dual motors, dual reducers, and dual axis transmission to perform cantilever shaft revolution and mixing shaft rotation. The mixing shaft is equipped with a specially designed sanitary double end face machine seal.
2. Cylinder body: The cylinder body consists of a head and a conical cylinder body. The head and cylinder body are equipped with jacket heating and insulation, necessary manholes, process pipe openings, sight glasses, stable pressure, long service life, agitator, bottom discharge valve, upper feed valve, and dust filter.
3. Dust filter: The dust filter consists of an insulated and heated outer cylinder, a filter element, a blowback and cleaning device.
4. Mixing screw: The screw itself is conical, and the diameter of the screw thread rises from the bottom to the top. The mixing screw is completely cantilevered to avoid the need for a bottom support bearing, a sturdy central gearbox component, and a top bearing arrangement. The mixing screw has a hollow sturdy central shaft and a spiral scraper continuously welded to the central shaft. The double-sided hollow spiral scraper forms a heating circuit with the hollow central shaft.
5. Machine seal system: The machine seal sealing liquid is used as an external liquid barrier and a safe machine seal indicator system, designed with a thermosiphon cycle or pump cycle and an electric control switch. All mechanical seals of the dryer pass through a common cycle, and the two internal loop systems between the two end face machine seals are connected to an external liquid storage and lubrication sealing liquid storage tank, so as to obtain safe and preventive control of seal integrity through monitoring the liquid level. The mechanical seal product and connecting components comply with GMP standards, and the tank is filled with sterile water liquid for operation. The liquid system that can be circulated and completely emptied operates in accordance with GMP standards.
6. Inflatable sealed hemispherical valve (vacuum dryer feeding and discharging valve): This hemispherical valve is designed to meet the special needs of single cone vacuum dryer feeding and discharging. The valve is manufactured according to precise tolerance standards and combined with special structures to form a good vacuum and pressure sealing environment. The standard inflatable sealed design has no dead corners, is easy to clean, meets GM standards, and can be cleaned online.
