Automated processes are standard practice in the meals industry. Production efficiency just isn’t the only motivation, hygiene additionally plays a key position in the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss how to design a drive to meet these requirements and incorporate both these targets.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is chosen to meet the high necessities for hygiene in the meals trade, we normally recommend our ADVANCED LINE air vane motors. All their external elements are produced from chrome steel and are impervious to regular cleansing brokers. The smooth surface of those air motors is straightforward to clean. The drives are so properly sealed with sturdy 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 generally used cleaning spray methods. เกจวัดแรงกด is no concern for this motor. It may even be used underwater as in 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 discount of approx. 10-20% based on the technical knowledge said within the product catalog ought to be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast other features for such applications?
Answer: Yes. In many functions, condensation can form in air supply strains. It is subsequently advisable that measures are taken to ensure that the motor is not positioned on the lowest level within the system and that it can be flushed out with water. Many customers take precautionary measures, not solely relating to the structure of the motor of their system, but also concerning using water separators or dryers in entrance of the drive. If all this isn’t possible, then we recommend a special coating for those components inside the motor’s inside that are made from stainless steel. This is as a result of there is a limit to the usage of stainless-steel for heavy obligation, high-speed inner parts. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you’ve any examples of the place your motors can be utilized in the meals industry?
Answer: Stirring dough, transferring and slicing sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food trade purposes are infinite. I’ll describe a quantity of applications in additional element, such as the utilization 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 velocity of 700 rpm.
We also have the ideal 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 velocity of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of 63 mm.
Another application could be found in grinding mills and conveying systems for grain processing. In this case, the main target is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly explosive environments. You will even discover our motors used within the processing of meat, for example 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 wooden skewer through pieces 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 utility.
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 primary advantages is its high power 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 using a handheld system however in fact additionally for robotic techniques where the drive moves with the robot arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic supply of power – it doesn’t evaluate to the hazards of electrical energy. The energy output from the air motor over extensive torque ranges is nearly fixed. Air motors can therefore be optimally operated in a wide field of fluctuating masses. There isn’t any drawback with load being utilized on the air motor till standstill, no damages are incurred. This means it is much less apt to stalling. After discount of the load, it’s going to run once more immediately and any variety of successive occasions. Air motor power could be tailored just by adjusting the operating pressure. The velocity is lowered easily by throttling the air volume. Throttling supply air is beneficial when torque must also be considerably reduced. Exhaust air throttling ought to be chosen to scale back pace with none critical influence on the torque.
Question: Air motors are sometimes seen to be less efficient compared to 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 depends on the circumstances of the applying. Let me use this instance to elucidate: 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 period to safe the packaging tape. Electric motors cannot be loaded over a protracted time frame without operating the chance of overheating. Therefore, for this packaging machine, an electric motor would want to withstand excessive masses and consequently 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 favourable torque traits of air motors, a lower-powered drive will suffice. You could select 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 pace at 450 rpm under mild load. เกจวัดแรงดันน้ำมันเบนซิน required for this air motor is due to this fact solely 430W. The power stability of an air motor is seen in a totally completely different mild when you think about that the air motor needed for this packaging machine would solely require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on a long time of experience in the area of air motors. They have a variety of high quality, globally popular industrial drive options. Are the ADVANCED LINE motors a particular answer for food 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 satisfy the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established reliable drive options for the meals business and medical technology.
