Automated processes are standard apply within the food trade. Production efficiency is not the only 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 satisfy these requirements and incorporate each these targets.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to make sure that the right drive is chosen to satisfy the excessive requirements for hygiene within the meals business, we often advocate our ADVANCED LINE air vane motors. All their exterior components are made from stainless steel and are impervious to regular cleansing agents. The smooth surface of these air motors is simple to clean. The drives are so properly 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 immune to water penetration from generally used cleansing spray techniques. A moist environment is not any concern for this motor. It may even be used underwater as within the case of many stirring functions. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A energy reduction of approx. 10-20% primarily based on the technical data acknowledged in the product catalog ought to be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In many purposes, condensation can type in air provide traces. It is subsequently advisable that measures are taken to guarantee that the motor isn’t situated at the lowest point within the system and that it can be flushed out with water. Many customers take precautionary measures, not only regarding the format of the motor in their system, but in addition regarding using water separators or dryers in front of the drive. If all this is not potential, then we recommend a special coating for those components throughout the motor’s inside that are made from stainless steel. This is as a result of there is a restrict to the use of stainless steel for heavy obligation, high-speed inner parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you may have any examples of the place your motors can be used within the meals industry?
Answer: Stirring dough, moving and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade functions are countless. I’ll describe a number of purposes in additional element, corresponding to 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 on the speed of seven hundred rpm.
We even 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 pace of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of 63 mm.
Another utility may 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 potentially explosive environments. You will even discover 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 picket skewer via items of meat, onion and pepper. Pressure on 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 advantages 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 principle benefits is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a 3rd of its dimension. This is particularly important when using a handheld device but of course also for robotic techniques the place the drive moves with the robotic arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic source of energy – it doesn’t compare to the hazards of electricity. The energy output from the air motor over wide torque ranges is nearly constant. Air motors can due to this fact be optimally operated in a large subject of fluctuating masses. There is no drawback with load being applied on the air motor till standstill, no damages are incurred. This means it is much less apt to stalling. After reduction of the load, it’ll run again immediately and any variety of successive occasions. Air motor power could be tailored just by adjusting the operating strain. The speed is decreased easily by throttling the air quantity. Throttling provide air is beneficial when torque must also be significantly reduced. Exhaust air throttling must be chosen to reduce pace without any critical affect on the torque.
Question: Air motors are sometimes seen to be much less environment friendly in comparison with electrical motors. Can you comment on this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one foundation. The efficiency of a drive all the time depends on the situations of the applying. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at lowered pace over a protracted time period to safe the packaging tape. Electric motors cannot be loaded over a long time period without running the chance of overheating. Therefore, for this packaging machine, an electrical motor would wish to resist excessive loads and consequently would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You may select an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs close to idle speed at 450 rpm beneath light load. The power required for this air motor is due to this fact solely 430W. The power steadiness of an air motor is seen in a very completely different gentle when you assume 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 replicate on decades of expertise within the area of air motors. They have a broad range of high quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special solution for meals trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our normal program has been adjusted to fulfill the wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established reliable drive options for the food trade and medical technology.
