Automated processes are commonplace follow in the food business. Production effectivity isn’t the one motivation, hygiene additionally plays a key position in 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 goals.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the proper drive is selected to satisfy the high requirements for hygiene within the meals trade, we often advocate our ADVANCED LINE air vane motors. All their external parts are produced from stainless steel and are impervious to regular cleaning agents. The easy floor of these air motors is easy to wash. The drives are so properly sealed with durable 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 proof against water penetration from generally used cleaning spray methods. A wet surroundings is not any concern for this motor. It can even be used underwater as within the case of many stirring functions. All our ADVANCED LINE stainless-steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A power discount of approx. 10-20% based mostly on the technical data stated in the product catalog ought to be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast other options for such applications?
Answer: Yes. In many applications, condensation can form in air supply traces. It is due to this fact advisable that measures are taken to make sure that the motor is not situated at the lowest point in the system and that it might be flushed out with water. Many customers take precautionary measures, not only relating to the layout of the motor of their system, but in addition regarding the use of water separators or dryers in front of the drive. If all this is not attainable, then we recommend a particular coating for those components within the motor’s interior which are produced from stainless-steel. This is because there’s a restrict to the utilization of stainless-steel for heavy responsibility, high-speed inside elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of where your motors can be utilized within the meals industry?
Answer: Stirring dough, shifting and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food business purposes are infinite. I’ll describe a few purposes in more element, such as the usage of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator at the velocity of 700 rpm.
We also have the perfect drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within the smallest of spaces. The 900W high-torque motor with a nominal velocity of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another application may be found in grinding mills and conveying systems for grain processing. In this case, the primary focus is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in probably explosive environments. You will even find our motors used within the processing of meat, for example in a semi-automatic meeting 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 software.
Question: What benefits does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the principle advantages is its high power density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a 3rd of its measurement. This is especially vital when using a handheld device but after all also for robotic techniques where the drive moves with the robot arm.
Heat also leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of energy – it doesn’t examine to the dangers of electrical energy. The power output from the air motor over broad torque ranges is kind of fixed. Air motors can due to this fact be optimally operated in a wide field of fluctuating hundreds. There isn’t any downside with load being applied on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’ll run again immediately and any number of successive occasions. Air motor power could be adapted simply by adjusting the working stress. The velocity is lowered smoothly by throttling the air volume. Throttling supply air is beneficial when torque should also be considerably reduced. Exhaust air throttling must be chosen to scale back velocity with none serious affect on the torque.
Question: Air motors are often seen to be much less efficient in comparison with electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The efficiency of a drive always is determined by the situations of the applying. Let me use this example to explain: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at reduced speed over a long time period to secure the packaging tape. Electric motors cannot be loaded over an extended time period with out operating the danger of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to high hundreds and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very different story with the air motor: Due to the favourable torque traits 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 under that of the nominal torque, the air motor runs near idle pace at 450 rpm under gentle load. The energy required for this air motor is therefore only 430W. The energy stability of an air motor is seen in a totally totally different gentle when you assume about that the air motor wanted for this packaging machine would solely require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of experience in the field of air motors. They have a wide range of high of the range, 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 many years and our standard program has been adjusted to fulfill the wants of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established dependable drive solutions for the food industry and medical expertise.
