FEATHRE & BENEFITS

• Intensive Mixing by means of semi-anchor mixer and efficient scraper system.
• Intensity of homogenizing can be regulated by means of adjustable grip between rotor and stator.
• Optimal vertical mixing as well as quick deaeration by means of mixing spiral.
• Clean and aseptic working as no seals in reach of the product.
• Clean air-free work due to vacuum application and closed system.
• Drawing-in of raw material directly into the turbine of the homogenizer by means of special sucking device.
• Vessel with double jacket in stainless steel inside and outside for heating and cooling by means of steam or electricity heated bath.

Anchor Mixer The machine is provided with a slow speed semi-anchor mixer which is fixed with bearings on a rigid column in the center. In order to make the opening of the cover possible, the motor was placed under the machine. There are, however, no seals or bearings in reach of the product. The anchor, which assures an optimal, horizontal mixing of the product is equipped with a moveable teflon scrappers. These can adapt themselves individually to the wall of the vessel and thus guarantee an optimal scrapping of the vessel and a quick temperature exchange between the product and the liquid contained in the double jacket.The anchor feeds product into the high speed disperser blade and ensures that the mixture is constantly in motion. The anchor can be provided with scrapers to remove materials from the interior vessel walls to enhance the heat transfer capabilities of the mixer.         Homogenizer – (High Shear Mixer Rotor / Stator Mixing Impeller) The key to creating finest emulsion is to creat finest possible droplet size. The more the energy in the mix, the smaller the droplet size in emulsion, creating fine emulsion.high shear batch mixer doesn’t simply mix; it emulsifies, homogenizes, solubilizes, suspends, disperses and disintegrates solids. Each mixer, with its precision-engineered Silverson rotor/stator workhead, far outperforms conventional mixers, cutting processing times by up to 90%, improving quality, product consistency and process efficiency. Eliminate agglomerates and fish eyes Create stable emulsions and suspensions Reduce particle size Rapidly dissolve solids Accelerate reactions STEP 1 STEP 2 STEP 3 The high-speed rotation of the rotor blades within the precision-machined mixing workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead. Centrifugal force then drives materials towards the periphery of the workhead where they are subjected to a milling action in the precision-machined clearance between the ends of the rotor blades and the inner wall of the stator. This is followed by intense hydraulic shear as the materials are forced, at high velocity, out through the perforations in the stator and circulated into the main body of the mix. The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead maintaining the mixing cycle. The effect of the horizontal (radial) expulsion and suction into the head is to set up a circulation pattern that minimizes aeration caused by the disturbance of the liquid’s surface.     ROTOR / STATOR MIX HEAD TYPES   The Wetting Head (A) orDisintegrating Head, with large round holes works best for general purpose mixing. This is the most versatile of all the heads, giving an exceptionally vigorous mixing action and rapidly reduces the size of large particles.. Ideal for general mixing applications, its uses also include the disintegration of solids and the preparation of gels and thickeners, suspensions, solutions and slurries. The Slotted Head (B) provides the most popular combination of high shear and efficient flow rate. It is ideal for emulsions and medium-viscosity materials.For the disintegration of fibrous materials such as animal and vegetable tissue, as well as the disintegration and solubilization of “elastic” materials such as rubbers and polymers The Fine Hole Head (C) provides the highest shear possible − at the expense of a slower flow rate. It is most suitable for low-viscosity emulsions and fine dispersions.Provides exceptionally high shear rates ideal for the rapid size reduction of soluble and insoluble granular solids. It is also suitable for the preparation of emulsions and fine colloidal suspensions     Spiral Mixer The purpose of the mixing spiral is to intensify the vertical mixing of the product and thereby ensure a better and quicker de-aeration. The mixing spiral transports the product from the bottom of the vessel to the surface of the vacuum zone, where it is continuously de-aerated.With this triple mixing system a separate or subsequent de-aeration of the system is not necessary, Mixing, Hmogenizing, Heating, Cooling and de-aeration all takes place in one operation. Fluid to pasty products can be processed. The Multi-Homo type Super-Duomixer is also able to quickly disperse considerable quantities so that a fine and completely air-free mixture is produced.We are specialist in mixing and homogenizing systems, batch and continuous production installations and would be pleased to your partner in the planning and construction of your production equipment. Disperser Mixer The blade creates a vortex that pulls in the contents of the vessel to the blades sharp edges. The blade surfaces then mechanically tear apart solids thereby reducing their size, and at the same time dispersing them among the liquid used as the carrier fluid. High Speed Dispersers are ideal for dispersions that are up to a maximum of approx. 50,000 centipoise.
