Automated processes are standard follow in the meals industry. Production effectivity isn’t the only motivation, hygiene also plays a key role in the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to fulfill these requirements and incorporate each these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is selected to meet the excessive requirements for hygiene within the food industry, we usually suggest our ADVANCED LINE air vane motors. All their exterior components are created from chrome steel and are impervious to regular cleaning brokers. The clean surface of those air motors is straightforward to clean. The drives are so properly sealed with durable 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 resistant to water penetration from commonly used cleaning spray techniques. A wet surroundings isn’t any concern for this motor. It may even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless 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 information stated within the product catalog should 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 applications, condensation can form in air supply strains. It is therefore advisable that measures are taken to make sure that the motor just isn’t situated on the lowest point in the system and that it can be flushed out with water. Many users take precautionary measures, not solely regarding the structure of the motor of their system, but additionally concerning the usage of water separators or dryers in front of the drive. If all this isn’t attainable, then we advocate a particular coating for these parts throughout the motor’s inside that are produced from chrome steel. This is because there is a restrict to using stainless-steel for heavy responsibility, high-speed internal elements. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you have any examples of where your motors can be used in the food industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade applications are endless. I’ll describe a number of applications in additional element, similar to the use of 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 pace of seven hundred rpm.
We also have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of areas. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software could be found in grinding mills and conveying systems for grain processing. In this case, the focus is on dust generation 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 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 items of meat, onion and pepper. Pressure on 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 electrical motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the principle 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 3rd of its dimension. This is particularly important when utilizing a handheld gadget but in fact also for robotic techniques where the drive strikes with the robotic arm.
Heat additionally leaves the air motor cold. In important settings, compressed air is an unproblematic source of power – it doesn’t examine to the risks of electrical energy. The energy output from the air motor over wide torque ranges is nearly constant. Air motors can therefore be optimally operated in a wide area 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 less apt to stalling. After discount of the load, it will run once more instantly and any number of successive instances. Air motor energy can be adapted just by adjusting the operating pressure. The velocity is decreased smoothly by throttling the air volume. Throttling supply air is really helpful when torque must also be considerably lowered. Exhaust air throttling must be chosen to scale back velocity without any critical influence on the torque.
Question: Air motors are sometimes seen to be much less efficient compared to electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. pressure gauge 10 bar of a drive at all times depends on the circumstances of the appliance. Let me use this example to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at lowered speed over a long time frame to safe the packaging tape. Electric motors cannot be loaded over a protracted time period without operating the chance of overheating. Therefore, for this packaging machine, an electric motor would want to withstand high masses and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You might 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 speed at 450 rpm under light load. The power required for this air motor is therefore only 430W. The vitality steadiness of an air motor is seen in a very totally different light when you think about that the air motor wanted for this packaging machine would only require a third of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of experience within the field of air motors. ไดอะแฟรม have a variety of excessive quality, globally in style industrial drive options. Are the ADVANCED LINE motors a special solution for meals industry 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 prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects profit from long-established reliable drive options for the food business and medical technology.
