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

Automated processes are commonplace practice within the meals business. Production effectivity isn’t the only motivation, hygiene also plays a key role within the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to fulfill these necessities and incorporate both these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to make certain that the best drive is chosen to fulfill the high necessities for hygiene within the food business, we often advocate our ADVANCED LINE air vane motors. All their external elements are produced from stainless-steel and are impervious to normal cleaning agents. The easy floor of these air motors is easy to clean. The drives are so well sealed with durable long-life radial shaft seals that no air can escape and equally no dust, water or other solutions can penetrate the motor. The motors are even resistant to water penetration from commonly used cleansing spray systems. A wet surroundings is not any concern for this motor. It can even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A power reduction of approx. 10-20% based mostly on the technical information said in the product catalog should be taken into account when designing drives for oil-free operation.
Question: Does an air motor have to boast other options for such applications?
เครื่องมือวัดความดัน : Yes. In many applications, condensation can type in air provide lines. It is therefore advisable that measures are taken to make certain that the motor is not situated at the lowest point in the system and that it can be flushed out with water. Many users take precautionary measures, not solely referring to the structure of the motor in their system, but in addition concerning the use of water separators or dryers in entrance of the drive. If all this is not potential, then we advocate a particular coating for these parts throughout the motor’s inside that are produced from stainless steel. This is as a end result of there is a limit to using stainless-steel for heavy responsibility, high-speed inside elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you could have any examples of where your motors can be utilized within the food industry?
Answer: Stirring dough, moving and slicing sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are countless. I’ll describe a quantity of functions in additional detail, similar to using 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 pace of seven-hundred rpm.
We even have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within the smallest of areas. The 900W high-torque motor with a nominal speed of 22 rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software can be present in grinding mills and conveying systems for grain processing. In this case, the focus is on dust technology 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 in 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 by way of pieces 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 application.
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 main advantages is its excessive energy density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a third of its size. This is particularly vital when utilizing a handheld system however in fact additionally for robotic methods the place the drive strikes with the robotic arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of energy – it does not compare to the hazards of electricity. The energy output from the air motor over extensive torque ranges is sort of fixed. Air motors can therefore be optimally operated in a wide subject of fluctuating hundreds. 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 again instantly and any variety of successive instances. Air motor energy could be adapted simply by adjusting the operating strain. The pace is lowered smoothly by throttling the air quantity. Throttling provide air is recommended when torque also needs to be considerably decreased. Exhaust air throttling should 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 in contrast on a one-to-one foundation. The efficiency of a drive at all times is decided by the situations of the application. Let me use this instance to explain: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at reduced speed over a protracted time period to safe the packaging tape. Electric motors cannot be loaded over a long time period with out running the risk of overheating. Therefore, for this packaging machine, an electric motor would want to resist excessive 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 beneficial 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 speed of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs close to idle velocity at 450 rpm under gentle load. The energy required for this air motor is due to this fact only 430W. The power balance of an air motor is seen in a totally totally different gentle when you assume about that the air motor needed for this packaging machine would solely require a 3rd of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of experience within the area of air motors. They have a variety of high of the range, globally well-liked industrial drive options. 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 standard program has been adjusted to fulfill the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients profit from long-established dependable drive options for the food business and medical expertise.
