Automated processes are commonplace practice in the food business. Production effectivity just isn’t the one motivation, hygiene additionally performs a key position within the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss the means to design a drive to meet these necessities and incorporate both these objectives.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make sure that the best drive is chosen to fulfill the high necessities for hygiene in the meals business, we usually advocate our ADVANCED LINE air vane motors. All their exterior components are produced from stainless-steel and are impervious to normal cleaning agents. The easy surface of these air motors is simple to clean. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no dirt, water or other solutions can penetrate the motor. The motors are even resistant to water penetration from generally used cleaning spray techniques. A wet setting is no 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 may be operated oil-free. A energy reduction of approx. 10-20% primarily based on the technical data acknowledged in the product catalog must 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 form in air provide lines. It is subsequently advisable that measures are taken to ensure that the motor isn’t positioned on the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not only relating to the layout of the motor in their system, but also regarding the utilization of water separators or dryers in entrance of the drive. If all this is not attainable, then we advocate a particular coating for those components throughout the motor’s inside which are created from stainless steel. This is as a outcome of there is a restrict to the usage of stainless steel for heavy duty, high-speed internal components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be used in the meals industry?
Answer: Stirring dough, shifting and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals business purposes are countless. I’ll describe a quantity of functions in more detail, similar to the use 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 even have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of 63 mm.
Another software can be found 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 certified for use in doubtlessly explosive environments. เพรสเชอร์เกจ4นิ้ว will even discover 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 picket skewer via items of meat, onion and pepper. Pressure at the skewer is 38 kg and therefore 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 utilizing an air motor: One of the principle benefits 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 especially significant when utilizing a handheld system however after all also for robotic techniques where the drive moves with the robot arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of energy – it does not compare to the risks of electricity. The power output from the air motor over extensive torque ranges is almost fixed. Air motors can therefore be optimally operated in a large subject of fluctuating hundreds. There is not any drawback with load being utilized on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After reduction of the load, it will run again immediately and any variety of successive occasions. Air motor power can be adapted just by adjusting the working pressure. The pace is lowered easily by throttling the air quantity. Throttling supply air is beneficial when torque also wants to be significantly reduced. Exhaust air throttling ought to be chosen to reduce speed without any severe affect on the torque.
Question: Air motors are often seen to be much less efficient in comparability with electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one foundation. The efficiency of a drive all the time is determined by the circumstances of the application. 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 reduced velocity over a protracted period of time to secure the packaging tape. Electric motors cannot be loaded over an extended period of time without running the danger of overheating. Therefore, for this packaging machine, an electrical motor would want to face up to high loads and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You might 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 near idle velocity at 450 rpm under light load. The power required for this air motor is due to this fact only 430W. The power stability of an air motor is seen in a totally completely different light when you think about that the air motor wanted for this packaging machine would only require a 3rd of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of expertise in the field of air motors. They have a variety of excessive quality, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a particular resolution for meals trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our normal program has been adjusted to meet the wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers benefit from long-established reliable drive options for the meals trade and medical expertise.
