Hoe kiest u het beste roerwerk voor uw melksilo

Een roerwerk bevat verschillende onderdelen, zoals lagers, afdichtingen en koppelingen, maar er zijn er die waar u vooral op met letten bij het aanschaffen. De as, bladen en motor zijn drie essentiële onderdelen waarvoor bij elke aankoop andere overwegingen gelden. Verschillende producttypes en productiebehoeften bepalen welke combinatie van deze drie onderdelen u kiest.

Vertical or Horizontal Shaft

Should you install your agitator with the shaft vertical from the top or horizontally from the side? The answer depends on a variety of factors. Generally, horizontal agitators are used for larger tanks while vertical ones work well for smaller ones. The vertical agitator works by exerting downward force on the liquid while horizontal agitators typically work by driving the liquid along straight paths along the bottom of the tank then upward. One of the reasons a food processor might choose horizontal agitators is due to the reduced risk of sheering the product. Vertical agitators have to spin faster to push the liquid to the bottom of the tank so the increased speed may run the risk of deteriorating some of the solids instead of evenly distributing them.

Blade Type

A few common types of agitator blades in the food processing industry include propeller, anchor and paddle blades. The blade type depends on the type of product you are trying to agitate. Molasses will have a different viscosity and density than milk which will require a different type of blade to be installed.  Some blades will require more energy to operate but this is not necessarily a negative as your particular product may not agitate well with smaller blades. Your product, tank size and processing goals each play a role in determining how to choose you blade.

Motor

The choice of an agitator motor is similar to the blade – you must take your product, tank size and processing goals into consideration. There are also a few more things to consider. How much of a load cushion are you allowing for your motor? Are you installing one that will need to use 100% of its load capacity or less? Running a motor at a full load will reduce its efficiency so you should install a motor with a little more power than the load would dictate. You should also consider whether the volume of product within your tank will vary. If you are utilizing less than full capacity in your tank, then the settings on your motor should be adjusted accordingly.

Conclusion

When choosing an agitator, it would be wise to ask yourself what your unique circumstances are and to make a purchase based on that. A good vendor will help walk you through the process and ask question without presuming to know the answer. Click here to chat with one of our experts today.
