Automated processes are standard follow within the meals business. Production effectivity just isn’t the one motivation, hygiene additionally plays a key role in the meals business. 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 each these objectives.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the right drive is selected to satisfy the high necessities for hygiene within the meals business, we normally recommend our ADVANCED LINE air vane motors. All their exterior elements are produced from stainless-steel and are impervious to normal cleansing brokers. The easy surface of these air motors is easy to wash. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no dirt, water or different solutions can penetrate the motor. The motors are even proof against water penetration from generally used cleansing spray systems. A wet surroundings is no concern for this motor. It may even be used underwater as within the case of many stirring applications. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A energy reduction of approx. 10-20% based on the technical data stated in the product catalog should be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast different options for such applications?
Answer: Yes. In many purposes, condensation can kind in air provide strains. It is therefore advisable that measures are taken to make certain that the motor isn’t located on the lowest level within the system and that it may be flushed out with water. Many users take precautionary measures, not only relating to the structure of the motor in their system, but also regarding using water separators or dryers in front of the drive. If all this is not possible, then we suggest a particular coating for those elements throughout the motor’s interior that are made from stainless-steel. This is because there’s a limit to using chrome steel for heavy obligation, high-speed inner parts. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be used in 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 functions are infinite. I’ll describe a few functions in more detail, corresponding 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 at the velocity 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 within the smallest of areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a starting torque of 585 Nm and has a maximum diameter of sixty three mm.
pressure gauge 10 bar could be found in grinding mills and conveying techniques for grain processing. In this case, the focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in doubtlessly explosive environments. You will even find 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 wood skewer via items of meat, onion and pepper. Pressure on the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this application.
Question: What advantages does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the principle advantages is its excessive power 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 vital when utilizing a handheld device but of course additionally for robotic techniques the place the drive strikes with the robotic arm.
Heat also leaves the air motor cold. In important settings, compressed air is an unproblematic source of vitality – 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 due to this fact be optimally operated in a large area of fluctuating hundreds. There is not 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 reduction of the load, it will run again immediately and any number of successive occasions. Air motor energy may be tailored simply by adjusting the operating pressure. The pace is decreased smoothly by throttling the air quantity. Throttling supply air is beneficial when torque also wants to be considerably decreased. Exhaust air throttling ought to be chosen to cut back speed with none critical affect 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 cannot be in contrast on a one-to-one basis. pressure gauge 10 bar of a drive always depends on the circumstances 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 utilized at lowered pace over a long time period to secure the packaging tape. Electric motors cannot be loaded over an extended time frame without running the danger of overheating. Therefore, for this packaging machine, an electrical motor would wish to withstand high loads and in consequence would need 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 may choose an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs near idle pace at 450 rpm underneath mild 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 completely different mild when you suppose about that the air motor wanted for this packaging machine would solely require a 3rd of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of expertise within the area of air motors. They have a extensive range of top of the range, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special solution for food industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our normal program has been adjusted to fulfill the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our customers profit from long-established reliable drive solutions for the meals industry and medical expertise.
