Though we offer removable drum type mixers as standard practice, we also offer design similar to the 2D conventional Blenders.
In this design, the mixing barrel is fixed as the rotating cage and so is non removable. The powder to be mixed is simply filled in this rotating barrel. Such kind of configuration is suitable for single and fixed mixing application. This frees customer from having separate mixing containers.
Typical applications
It is ideal for use in medium to large batch production industries like food/nutrition, pharmaceuticals, metal powder, resin and plastic powder, bakery, spices, concentrates, nuclear fuel and many more applications.
Mixing drum is non removable
- Alphie mixer are also offered as Fixed Drum or Non Removable Container design. As the name suggests, the mixing drum is fixed and so can not be taken out. The powder to be filled has to be charged/loaded in the mixing drum and same is collected from bottom discharge after mixing.
- If the mixing application or ingredients are same and there is no need to change the material – Non Removable Drum design can be used. They are further more suitable for large capacity mixing requirements.
Construction
- Standard mixers are built with structure made from Carbon steel. They are powder coated material after surface preparation.
- We also offer GMP design where all exposed parts are made from Stainless Steel AISI 304 material.
- Mixing Drum material can be Stainless Steel AISI 304 or AISI 316L or any other material required.
Non linear shaft design:
- Both the shafts of mixer are inclined at a particular angle to ensure better homogeneity and easy discharge. Alphie design engineers calculate the discharge angle based on your powder characteristics and Angle of Repose.
Powder loading options
- Powder can be loaded either Manually or using Vacuum Suction System or Conveyor etc. Contact us to work out best solution for your requirement. We also offer customised design.
Safety guard
- All mixers are built with a safety rail guard to protect human from moving parts. The mixer shall stop, if the guard is opened and mixer can not start unless the guard is closed.
- Various guard designs are offered like – fully covered plexi glass construction, guard on wheels etc as per customer requirements.
Fixed stop position –
- After cycle completion, mixer stops at predefined position on its own for easy drum loading and unloading.
Control panel
- Alphie mixers are built with HMI/PLC panel and Variable Frequency Drive (VFD) as standard supply. User can set the Container Speed, Mixing time and Mixing direction.
- Mixer panel is programmed with the ability to set mixing in forward direction for some part of mixing cycle and in reverse direction in other part of cycle time. This is especially beneficial for mixing diverse density material.
- Mixer has Recipe mode, where speed and time can be set with password protection.
- Our control panels are built accordance to CE certification.
Operator Friendly Panel Features
- Mixer automatically stops at home/container loading position following completion of each mixing cycle.
- Actual process times, set speeds and direction of rotation are clearly indicated during mixing cycle.
- Mixing cycle can be paused/resumed at any time without loss of parameters.
- Mixer comes at the pause state when safety guard is opened.
- Operator can resume the batch without loss of parameters when safety guard is closed.
- PLC retains time remaining value upon start-up following power failure and/or e-stop event to resume blending seamlessly.
Life long access to documents from our web server
- QR code pasted on machine name plate for scanning
- Life long access to the technical documents in soft copy
- Access to the Video training instructions
- Download operating manual wiring diagram etc.
Option of mixing in controlled atmosphere using glove box/isolator (+ve or -ve pressure)
- Alphie mixers can be designed and manufactured so the mixing drum can remain in the glove box/isolator and drive part remain outside.
Option of injecting liquid while mixing
- As an optional feature, Alphie 10 can be constructed to have provision to inject liquid in the mixing chamber while mixer is running. A pre defined quantity of liquid at required interval can be inserted in mixing container without stopping the mixer.
Option of control panel with 21 CFR, part 11 compliance
- We can supply mixer for Pharmaceutical industry complying the 21 CFR regulatory requirements.
Medium / Pilot Capacity : All of these models are offered in Powder coated Carbon steel as well as Stainless Steel GMP construction option.

We offer customised volume design and can supply as big as 3000 Ltr of such mixers. Please contact us for more details.
- How much should I fill the material in mixing bottle? It is always good not to fill more than 70% of bottle total volume. We recommend filling upto 40 – 50%. Mixing time increases exponentially when filled more than 50% of volume.
- What should be the correct mixing speed? It is not correct to assume that running at high speed will do fast and better mixing. In many applications, high speed gives adverse mixing results. In normal mixing cases, mixing at 50% of maximum permissible speed should be sufficient to start with.
- Is there any preference on mixing direction? Should i rotate the bottle in clockwise or anti clockwise direction? – There is no preference or rule of mixing direction. You can rotate in any direction suitable to you. However, few of the customers have got better and quicker mixing results when rotated in one direction for half the time and in opposite direction in remaining half batch time.
- How long should I mix? This depends on many variables like % of bottle filled, powder condition etc. However, most applications start getting results in 5 to 15 minutes. Its a myth that more mixing gives better homogeneity.
- Is there any shear force acting while mixing? Alphie mixer runs on the principle of kinematic inversion. So, the bottle does not rotate, but it inverts. So this is theoretically zero shear force mixing.
- Can Alphie be used for liquid mixing also? Yes, Alphie can be used for powder, liquid and suspensions.
- What is the material of mixing drum suitable for my application? As standard, we offer AISI 304 as mixing drum material. For some cases, we can offer AISI 316L or other material also.
- How load the powder in the mixer? Mixers have lid with suitable diameter for powder loading/charging. Mixer stops at pre-defined position and powder can be filled inside using vacuum transfer/from hopper or manually.
- How can I discharge material from the mixer? As a special design feature, mixer drum is designed in such a way that it stops at an angle suitable for complete discharge. By opening bottom buterfly valve, material can be removed and collected in bin/hopper.
- Does big capacity Alphie mixer needs grouting or foundation? Mixers supplied upto 35 Ltr are supplied with self levlling pads. You just keep on flat surface and level it by levelling pads of mixer. Mixers 50 Ltr and above can be grouted.
- Can we add balls in mixing container? Yes, suitable size stainless steel or other material balls can be added. They can be sourced from us also.
- How can I learn more about how to use this mixer? Mixer is supplied with Instruction Manual copy placed inside the tray. Further, a QR code sticker has been placed on the body of mixer near its name plate. Scanning it, will take you to the video of how to use this mixer.
- Do you send CE certificate and other documents with the mixer? Yes, if your mixer is supplied as CE compliance mixer; certificate shall be sent along with the mixer. All mixers are marked with QR code, scanning which you can find all related documents and operating video.
- Can you supply mixer complying CE requirement? Yes, Alphie 10 can be supplied complying the CE requirements.
- I am not staying in India. How can you give me after sales support? Our team is available all the time to respond your query and give online support for any of your queries. Further, we have developed video instruction for most of trouble shooting which customer can do on his own
