Automated processes are standard apply within the food business. Production efficiency isn’t the one motivation, hygiene also performs a key role in the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to satisfy these requirements and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make sure that the right drive is chosen to fulfill the excessive requirements for hygiene in the meals business, we usually suggest our ADVANCED LINE air vane motors. All their exterior elements are made from chrome steel and are impervious to normal cleaning agents. The clean floor of these air motors is easy to scrub. The drives are so properly sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or different solutions can penetrate the motor. The motors are even immune to water penetration from commonly used cleaning spray systems. A wet setting is no concern for this motor. It may even be used underwater as in the case of many stirring applications. All our ADVANCED LINE chrome steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A energy reduction of approx. 10-20% primarily based on the technical knowledge acknowledged within the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast other options 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 sure that the motor is not located on the lowest point in the system and that it may be flushed out with water. Many customers take precautionary measures, not only referring to the layout of the motor of their system, but also regarding the use of water separators or dryers in entrance of the drive. If all this isn’t attainable, then we suggest a particular coating for those parts within the motor’s interior which are produced from chrome steel. This is as a result of there’s a restrict to using stainless-steel for heavy obligation, high-speed internal elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be utilized in the food industry?
Answer: Stirring dough, shifting and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food industry purposes are infinite. I’ll describe a number of purposes in more element, corresponding to using our ADVANCED LINE air motor in an agitator for the production of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator on the speed of 700 rpm.
We even have the best drive for high-torque requirements 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 velocity of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another utility may be present in grinding mills and conveying systems for grain processing. In this case, the focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in doubtlessly explosive environments. You will even find our motors used in 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 through 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 application.
Question: 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 principle advantages is its high power density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its dimension. This is particularly important when utilizing a handheld system however of course also for robotic systems where the drive moves with the robot arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic source of energy – it doesn’t evaluate to the risks of electricity. The power output from the air motor over wide torque ranges is kind of constant. Air motors can subsequently be optimally operated in a large field of fluctuating loads. There isn’t any downside with load being utilized on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After reduction of the load, it’s going to run once more immediately and any number of successive instances. Air motor energy can be tailored simply by adjusting the working pressure. The pace is reduced easily by throttling the air volume. Throttling supply air is recommended when torque must also be significantly reduced. Exhaust air throttling must be chosen to minimize back pace with none critical affect on the torque.
Question: Air motors are sometimes seen to be much less efficient compared to electrical motors. Can you touch upon 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 depends on the conditions of the appliance. 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 applied at decreased speed over a long time period to secure the packaging tape. Electric motors cannot be loaded over a protracted period of time without operating the chance of overheating. Therefore, for this packaging machine, an electric motor would need to withstand high loads and in consequence would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally different story with the air motor: Due to the favourable torque characteristics 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 below that of the nominal torque, the air motor runs near idle speed at 450 rpm under mild load. The power required for this air motor is due to this fact solely 430W. The vitality steadiness of an air motor is seen in a totally completely different gentle when you consider that the air motor needed for this packaging machine would only require a 3rd of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of experience in the field of air motors. They have a extensive range of high quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special resolution for food trade applications?
