Automated processes are commonplace follow in the meals industry. Production effectivity isn’t the one motivation, hygiene additionally plays a key role in the food trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to satisfy these requirements and incorporate each these targets.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to make certain that the proper drive is chosen to satisfy the excessive requirements for hygiene in the meals trade, we often suggest our ADVANCED LINE air vane motors. All their external components are created from chrome steel and are impervious to normal cleansing agents. The clean surface of those air motors is easy to clean. The drives are so well sealed with durable long-life radial shaft seals that no air can escape and equally no filth, water or different options can penetrate the motor. The motors are even immune to water penetration from generally used cleansing spray methods. A wet environment is not any concern for this motor. It may even be used underwater as in the case of many stirring functions. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A power reduction of approx. 10-20% based mostly on the technical knowledge acknowledged within the product catalog must be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor must boast different options for such applications?
Answer: Yes. In many applications, condensation can type in air supply traces. It is due to this fact advisable that measures are taken to guarantee that the motor isn’t located on the lowest level within the system and that it can be flushed out with water. Many customers take precautionary measures, not only relating to the format of the motor of their system, but also concerning the use of water separators or dryers in entrance of the drive. If all this is not possible, then we recommend a particular coating for those components inside the motor’s inside that are made from stainless steel. This is as a end result of there’s a restrict to using chrome steel for heavy responsibility, high-speed inner elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be used in the meals industry?
Answer: Stirring dough, moving and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business functions are endless. I’ll describe a few purposes in more element, corresponding to using 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 on 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 power within the smallest of spaces. The 900W high-torque motor with a nominal velocity of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of 63 mm.
Another software may 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 licensed for use in doubtlessly explosive environments. You will even discover our motors used within 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 by way of pieces of meat, onion and pepper. Pressure on the skewer is 38 kg and due to this fact a high-power air motor with compact design is ideally suited to this utility.
Question: What advantages 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 primary advantages is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its dimension. This is particularly significant when using a handheld gadget however after all additionally for robotic techniques the place the drive moves with the robot arm.
Heat additionally leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of power – it does not compare to the risks of electrical energy. The power output from the air motor over extensive torque ranges is almost constant. Air motors can subsequently be optimally operated in a wide field of fluctuating masses. There is not any problem with load being applied on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After reduction of the load, it’ll run again immediately and any number of successive instances. Air motor power could be adapted simply by adjusting the working pressure. The velocity is reduced easily by throttling the air volume. Throttling provide air is really helpful when torque must also be significantly lowered. Exhaust air throttling ought to be chosen to reduce speed without any serious influence on the torque.
Question: Air motors are often seen to be much less efficient compared to electric motors. Can you touch upon this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The effectivity of a drive all the time is decided by the conditions of the appliance. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at lowered pace over an extended time frame to secure the packaging tape. Electric motors cannot be loaded over a long time frame without working the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to resist excessive loads and as a result would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very completely different story with the air motor: Due to the beneficial torque characteristics 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 below that of the nominal torque, the air motor runs close to idle velocity at 450 rpm underneath mild load. The power required for this air motor is therefore solely 430W. The vitality balance of an air motor is seen in a totally totally different gentle when you suppose about that the air motor needed for this packaging machine would only require a 3rd of the facility of an electric motor.
Question: DEPRAG SCHULZ GMBH u. เกจวัดแรงดัน . can mirror on many years of expertise in the area of air motors. They have a broad range of prime quality, globally well-liked industrial drive options. Are the ADVANCED LINE motors a special answer for food trade applications?
