Automated processes are commonplace apply within the meals trade. Production efficiency is not the one motivation, hygiene also plays a key function within the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to satisfy these requirements and incorporate each these goals.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is chosen to satisfy the high necessities for hygiene in the food business, we normally recommend our ADVANCED LINE air vane motors. All their external elements are produced from chrome steel and are impervious to regular cleaning agents. The clean surface of these air motors is easy to clean. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no dust, water or different options can penetrate the motor. The motors are even immune to water penetration from generally used cleaning spray techniques. A wet environment is no concern for this motor. It may even be used underwater as in the case of many stirring functions. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and could be operated oil-free. A power discount of approx. 10-20% based mostly on the technical knowledge acknowledged within the product catalog ought to be taken into account when designing drives for oil-free operation.
Question: Does an air motor have to boast other features for such applications?
Answer: Yes. In many purposes, condensation can kind in air supply traces. It is subsequently advisable that measures are taken to make certain that the motor just 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 solely regarding the layout of the motor of their system, but additionally concerning the utilization of water separators or dryers in front of the drive. If all this isn’t attainable, then we suggest a special coating for these elements throughout the motor’s inside that are made from chrome steel. This is as a result of there’s a limit to the use of chrome steel for heavy obligation, high-speed inside elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of where your motors can be used within the food industry?
Answer: Stirring dough, moving and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food industry applications are countless. I’ll describe a couple of purposes in additional element, similar 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 at the speed of seven-hundred rpm.
We also have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of spaces. 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 63 mm.
Another utility could be present in grinding mills and conveying techniques for grain processing. In this case, the major focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in doubtlessly explosive environments. You will even discover our motors used in the processing of meat, for instance 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 picket skewer by way of items of meat, onion and pepper. Pressure at the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this utility.
เกจวัดแรงดันน้ำ4หุน : 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 main advantages is its excessive 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 size. This is particularly significant when using a handheld device but after all additionally for robotic methods where the drive moves with the robotic arm.
Heat additionally leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of power – it doesn’t compare to the hazards of electricity. The power output from the air motor over extensive torque ranges is nearly fixed. Air motors can subsequently be optimally operated in a large subject of fluctuating hundreds. There isn’t any 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 will run once more immediately and any variety of successive times. Air motor power can be tailored simply by adjusting the working strain. The speed is lowered smoothly by throttling the air quantity. Throttling supply air is really helpful when torque also wants to be considerably decreased. Exhaust air throttling must be chosen to scale back pace with none critical influence on the torque.
Question: Air motors are sometimes seen to be much less environment friendly in comparability with electrical motors. Can you comment on this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one foundation. The effectivity of a drive all the time depends on the circumstances 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 decreased pace over a long period of time to secure the packaging tape. Electric motors cannot be loaded over a protracted time frame with out running the danger of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to excessive loads and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs near idle pace at 450 rpm underneath light load. The power required for this air motor is subsequently solely 430W. The energy balance of an air motor is seen in a completely different light when you consider that the air motor wanted for this packaging machine would solely require a 3rd of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of expertise in the area of air motors. They have a wide range of high quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular answer 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 commonplace program has been adjusted to satisfy the needs of our prospects.
