Automated processes are commonplace practice within the food industry. Production effectivity just isn’t the only motivation, hygiene additionally plays a key position within the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss how to design a drive to meet these requirements and incorporate each these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to guarantee that the best drive is chosen to meet the excessive necessities for hygiene within the meals business, we usually advocate our ADVANCED LINE air vane motors. All their exterior components are created from stainless-steel and are impervious to normal cleaning brokers. The easy floor of these air motors is simple to scrub. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or different solutions can penetrate the motor. The motors are even resistant to water penetration from commonly used cleansing spray methods. A moist environment is not any concern for this motor. It can even be used underwater as within the case of many stirring applications. เกจวัดแรงดันน้ำมันเครื่อง -steel motors are lubricated with food grade USDA-H1 grease and could be operated oil-free. A power reduction of approx. 10-20% primarily based on the technical information said within the product catalog ought to be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast other features for such applications?
Answer: Yes. In many applications, condensation can form in air provide lines. It is therefore advisable that measures are taken to ensure that the motor isn’t located at the lowest point in the system and that it could be flushed out with water. Many users take precautionary measures, not only regarding the format of the motor of their system, but in addition concerning the utilization of water separators or dryers in entrance of the drive. If all this isn’t attainable, then we suggest a particular coating for those elements inside the motor’s interior which are created from stainless-steel. This is as a end result of there’s a restrict to the usage of stainless-steel for heavy duty, high-speed inside components. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be utilized within the food industry?
Answer: Stirring dough, transferring and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are countless. I’ll describe a couple of functions in additional element, corresponding to the utilization of our ADVANCED LINE air motor in an agitator for the production of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator on the pace of 700 rpm.
We even have the best drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of spaces. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of 63 mm.
Another utility can be present in grinding mills and conveying systems for grain processing. In this case, the primary focus is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly explosive environments. You will even find our motors used within the processing of meat, for instance in a semi-automatic assembly system for the manufacture of kebab skewers. In the skewer unit, two air motors are used to drive belts which pierce a wooden skewer through pieces of meat, onion and pepper. Pressure at the skewer is 38 kg and due to this fact a high-power air motor with compact design is ideally suited to this software.
Question: What benefits does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the primary advantages is its high power density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a third of its dimension. This is especially significant when utilizing a handheld device but in fact also for robotic methods the place the drive moves with the robot arm.
Heat additionally leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of power – it doesn’t compare to the risks of electricity. The energy output from the air motor over broad torque ranges is nearly fixed. Air motors can therefore be optimally operated in a wide subject of fluctuating masses. There isn’t any drawback with load being utilized on the air motor until standstill, no damages are incurred. This means it is much less apt to stalling. After discount of the load, it’s going to run again instantly and any variety of successive instances. Air motor energy can be adapted just by adjusting the operating pressure. The speed is lowered easily by throttling the air quantity. Throttling provide air is beneficial when torque should also be considerably reduced. Exhaust air throttling should be chosen to reduce speed with none severe affect on the torque.
Question: Air motors are often seen to be less environment friendly in comparison with electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The efficiency of a drive all the time depends on the situations of the applying. Let me use this example to elucidate: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at lowered velocity over an extended period of time to secure the packaging tape. Electric motors can’t be loaded over a long time frame with out running the danger of overheating. Therefore, for this packaging machine, an electric motor would need to resist excessive hundreds and as a result would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very totally different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You may choose an air motor with a nominal torque of 15 Nm and nominal speed of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle velocity at 450 rpm under light load. The power required for this air motor is therefore solely 430W. The energy balance of an air motor is seen in a completely completely different mild when you assume about that the air motor needed for this packaging machine would only require a third of the facility of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on a long time of expertise in the subject of air motors. They have a variety of excessive quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular answer for food trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our commonplace program has been adjusted to meet the wants of our prospects.
