Ensure top-notch reliability with the best drive for the job

Automated processes are normal practice in the food trade. Production efficiency just isn’t the one motivation, hygiene also performs a key position within the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss the way to design a drive to fulfill these necessities and incorporate both these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is chosen to meet the excessive requirements for hygiene in the meals business, we often recommend our ADVANCED LINE air vane motors. All their external elements are made from chrome steel and are impervious to regular cleansing brokers. The clean floor of those air motors is easy to clean. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no dirt, water or different options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleaning spray methods. A moist setting is not any concern for this motor. It may even be used underwater as in the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A energy discount of approx. 10-20% based on the technical data stated in the product catalog should be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast other options for such applications?
Answer: Yes. In many functions, condensation can form in air provide strains. It is subsequently advisable that measures are taken to make sure that the motor just isn’t situated at the lowest level within the system and that it can be flushed out with water. Many customers take precautionary measures, not only relating to the structure of the motor of their system, but additionally concerning using water separators or dryers in entrance of the drive. If all this is not potential, then we advocate a special coating for those elements inside the motor’s interior that are produced from stainless-steel. This is because there’s a restrict to the use of stainless-steel for heavy responsibility, high-speed inside components. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you’ve any examples of the place your motors can be utilized in the food industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are endless. I’ll describe a few applications in more element, similar 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 speed of seven hundred 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 areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another software could be present in grinding mills and conveying techniques for grain processing. In this case, the focus is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in probably explosive environments. You will even find our motors used within the processing of meat, for example 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 wood skewer through items of meat, onion and pepper. Pressure on the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this utility.
Question: What benefits does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the primary advantages is its high energy 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 vital when using a handheld device however of course also for robotic methods the place the drive strikes with the robot arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic source of energy – it doesn’t examine to the hazards of electrical energy. The energy output from the air motor over broad torque ranges is almost constant. Air motors can therefore be optimally operated in a wide area of fluctuating masses. There isn’t any downside with load being utilized on the air motor until standstill, no damages are incurred. This means it’s much less apt to stalling. After discount of the load, it’ll run once more immediately and any number of successive times. Air motor energy can be tailored just by adjusting the operating stress. The pace is reduced smoothly by throttling the air volume. Throttling provide air is really helpful when torque also needs to be considerably reduced. ชนิดของpressuregauge throttling should be chosen to minimize back pace with none severe affect on the torque.
Question: Air motors are sometimes seen to be much less efficient compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be in contrast on a one-to-one foundation. The efficiency of a drive always depends on the situations of the appliance. Let me use this example to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at decreased pace over a long period of time to safe the packaging tape. Electric motors cannot be loaded over a protracted time frame with out working the risk of overheating. Therefore, for this packaging machine, an electrical motor would need to withstand high hundreds and consequently would must 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 characteristics of air motors, a lower-powered drive will suffice. You could choose an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs near idle speed at 450 rpm beneath gentle load. The energy required for this air motor is subsequently only 430W. The vitality stability of an air motor is seen in a totally different light when you think about that the air motor needed for this packaging machine would only require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on decades of expertise within the subject of air motors. They have a variety of high quality, globally popular industrial drive options. Are the ADVANCED LINE motors a particular solution for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our standard program has been adjusted to satisfy the needs of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established reliable drive options for the food trade and medical know-how.
