Ideal mixing quality for dry, moist and viscous materials at variable filling levels

The spiral mixing blade of the conical mixer initiates a three-dimensional flow of the mixing goods; creating a helical upward movement on the periphery and downward flow in the center. This blender guarantees very good mixing results and complete discharge. It can be used as powder blender for dry powder, wet suspensions as well as liquids, paste and dough. The vertical mixer can be designed for compliance with FDA and 3-A Sanitary Standards to be used as a sterile mixer and reactor which also meets EHEDG requirements.

Further characteristics of the powder blender and conical mixer

• If the mixing process requires deagglomeration, high speed cutting rotors can be installed.
• The mixing device is driven from the top, using only a single top bearing.
• The conical mixer meets all industry standards for surface finish, including sanitary and pharmaceutical requirements.
• Jacketed and vacuum rated versions are an ideal vacuum dryer or reactor.

Very gentle and best mixing quality for dry, moist and viscous materials at variable filling levels

The spiral mixing blade of the vertical mixer initiates a three-dimensional rearrangement of the mixing goods. This vertical mixer guarantees best mixing results. It can be used for dry powder, wet suspensions as well as liquids, paste and dough.

The vertical mixer can be designed for compliance with FDA and 3-A Sanitary Standards to be used as a sterile mixer and reactor which also meets EHEDG requirements.

Further characteristics of the vertical mixer

• The clockwise driven spiral tools initiate a three-dimensional flow of the mixing goods creating a spiral upward movement on the peripheries and downward flow in the center combined with horizontal cross flows.
• Vertical mixers can be used if a combination of heavy duty and very gentle mixing tasks have to be done subsequently.
• It can be used as powder blender for dry powder, wet suspensions as well as liquids, paste and dough.
• If the mixing process requires deagglomeration, high speed cutting rotors may be mounted.
• For dry, moist and viscous materials. Technical ideal mixing qualities can be guaranteed independent of filling level (10 to 100 % of the net volume), rpm-value of the mixing tools and characteristics of the mixing goods (for example: different bulk densities, particle sizes, flow abilities)
• Each vertical mixing device is driven from the top, using only a single top bearing.
• The twin shaft mixer meets all industry standards for surface finish, including sanitary and pharmaceutical requirements.

Powder mixer with an unconventional mixing chamber

amixon^® has developed an interesting innovation: a single-shaft powder mixing system with comparatively small dimensions. This precision powder mixer is characterized by particularly short mixing and discharging times, amongst other things. It is thus capable of processing large product quantities in a short cycle time.

Ideal mixing qualities and excellent particle protection are achieved in a new way. The mixing container consists of a silo-like container in whose center a large cone is inserted at the bottom. The powder mixer has a smooth, streamlined design and supports the flow process of the mixtures. Helical mixing tools convey the goods upwards in a spiral-like motion. This process takes place along the wall of the container.

Having arrived at the top, the goods slide downwards and are directed to the outside once again by the cone. The homogenization process takes place in the marginal area between the upward screwing and the downward movement. This process is gentle and effective.

After approximately 20 to 30 revolutions an ideal mixing quality is obtained that cannot be further improved in practice. The displacer then lowers itself by a few centimeters, so that the emptying takes place quickly and without residues. The mixer usually discharges into containers, big bags or the storage tanks of a filling machine. If the discharged mixture would land in the middle of the collecting container, a cone of material would form, leading to two disadvantages.

On the one hand, the entire intake capacity cannot be used and on the other, bulk material slopes can cause segregation effects. The mixtures are discharged off-center and segregation-free from the powder mixer described here.

amixon^® has test mixers in the most diverse sizes for process trials. Good results are assured in advance.

amixon^® Gyraton^® mixer for large batches

This large-volume mixer is a new development. It requires only low electrical connected loads. It mixes accurately, effectively and very gently. Gyraton^® mixers are also particularly cost-effective because they require very little installation space. The properties of the mixing goods are irrelevant. Even moist or poorly flowing materials (time-solidifying materials) are homogenized.

The function is similar to all other amixon^® mixers. But the specific energy input is lower with the Gyraton^® mixer. The mixer spiral rotates slowly and conveys the mixed materials upwards. It always touches only a part of the mixing chamber wall. In addition to rotation, the mixer shaft performs a circular path above the mixing chamber floor. The pivot point of the shaft lies in the plane of the gas-tight shaft seal. The entire cylinder surface is tangent to the mixing element spiral. This also applies to the bottom. Mixing takes place without dead space because the base is designed as a calotte. The lower mixing unit arm has the same curvature as the calotte shell.

The mixer shaft is only supported and driven at the top. The shaft sealing is permanently hygienic and gas-tight. The unit shown here can homogenize 70 m³ of mix. This is the content of a 40-foot deep-sea container. This mixer design requires very little installation space.

The mixer can optionally have one or more discharge nozzles.

The advantages that a Gyraton^® mixer offers, are exactly the reasons why amixon^® has developed this type of mixer:

• Gyraton^® mixers work particularly effectively with low motor power and homogenize your mixed materials especially gently.
• very low space requirement, due to the compact design. Most often, high-capacity mixers are located inside the building. Other large mixers have an upright conical mixing chamber. Such large conical mixers also have good mixing characteristics, but they require approximately three times the building height.
  
  To build a production hall correspondingly high is expensive. In addition, it is also permanently expensive if all your mixing goods have to be conveyed three times higher to reach the mixing chamber (large vertical conveyor and permanently higher operating costs).
• Gyraton^® mixers are designed in such a way that they can be transported lying on a low-loader truck, if possible. They are delivered ready-assembled. The height of the low-loader truck including freight is usually less than 4 meters. Freeway bridges can then be passed without difficulty within Europe.
• Gyraton^® mixers have large inspection doors. They can be conveniently inspected and cleaned. One can walk into the Gyraton^® mixers, they can be cleaned wet or dry if desired.
• There is no bearing or shaft seal in the product holdup. Only a shaft seal is present; this is located above the mix. However, this only seals against dust and gas and has an extremely long service life.
• Gyraton^® mixers can be equipped with one or with many discharge fittings. When large-volume homogenization of the mixed goods has taken place, it may be that the goods need to be quickly filled into containers, big bags, sacks or bags. This can be accelerated if there are several filling stations at the mixer.

In the amixon^® pilot plant, such a Gyraton^® mixer is available for tests. The usable volume is 3 m³. From the measurement data that amixon^® obtains during the mixing test, we can calculate very accurate design data for larger Gyraton^® mixers.

Hot/cold and pressure/vacuum reactions for dry, moist and viscous materials

Vacuum mixer-dryers and reactors from amixon® operate with vertically mounted helical blade mixing tools, which rotate at an uniform, close distance inside the mixing space. The small distance between the mixing tool and the wall of the container guarantees ideal heat transmission, particularly as all surfaces that come into contact with the products have a double jacket: the mixing tool shaft, the scoop-type arms and the helical blade. The special shape of the helical blade causes mixing and flow, without compacting or pressing the materials. Not only powders but also pastes and crystalline materials are reliably dried. Sometimes the consistency of the materials changes and viscoplastic phases have to be overcome during drying.

The dryers are manufactured according to the latest EHEDG guidelines as well as in compliance with GMP and FDA and are used for the gentle vacuum contact drying of powders.
