Automated processes are normal follow within the food trade. Production effectivity just isn’t the only motivation, hygiene also performs a key position in the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to meet these requirements and incorporate both these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make sure that the proper drive is chosen to satisfy the high requirements for hygiene within the food business, we usually advocate our ADVANCED LINE air vane motors. All their exterior parts are made from stainless steel and are impervious to regular cleaning brokers. The clean 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 options can penetrate the motor. The motors are even immune to water penetration from generally used cleaning spray methods. A wet surroundings is not 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% based mostly on the technical data stated in the product catalog should be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast other features for such applications?
Answer: Yes. In many applications, condensation can kind in air provide traces. เกจวัดแรงดันน้ำมันเครื่อง is due to this fact advisable that measures are taken to make certain that the motor is not positioned at the lowest level within the system and that it might be flushed out with water. Many users take precautionary measures, not only relating to the format of the motor in their system, but also concerning using water separators or dryers in front of the drive. If all this is not possible, then we advocate a particular coating for these parts throughout the motor’s interior which are created from chrome steel. This is as a outcome of there is a restrict to the use of stainless-steel for heavy duty, high-speed inside components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of where your motors can be used in the meals industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food industry functions are infinite. I’ll describe a few applications in more detail, similar 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 pace of seven hundred rpm.
We also have the perfect drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of spaces. 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 63 mm.
Another utility may be present in grinding mills and conveying techniques for grain processing. In this case, the main target is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in probably explosive environments. You will even find 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 picket skewer through 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 utilizing an air motor: One of the main 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 third of its dimension. This is especially important when utilizing a handheld gadget however of course additionally for robotic techniques where the drive strikes with the robot arm.
Heat additionally leaves the air motor chilly. In important settings, compressed air is an unproblematic source of power – it doesn’t examine to the dangers of electricity. The energy output from the air motor over wide torque ranges is type of fixed. Air motors can subsequently be optimally operated in a large area of fluctuating hundreds. There is เกจวัดแรงกด with load being utilized on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it will run once more instantly and any variety of successive occasions. Air motor power may be adapted just by adjusting the operating stress. The velocity is reduced easily by throttling the air volume. Throttling provide air is recommended when torque also wants to be significantly decreased. Exhaust air throttling ought to be chosen to cut back pace with none critical affect on the torque.
Question: Air motors are sometimes seen to be less environment friendly 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. The effectivity of a drive all the time is dependent upon the conditions of the applying. Let me use this example to elucidate: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at decreased speed over a protracted period of time to secure the packaging tape. Electric motors can’t be loaded over a long time period with out working the chance of overheating. Therefore, for this packaging machine, an electric motor would want to withstand excessive hundreds and as a result would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely 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 speed of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle pace at 450 rpm under light load. The energy required for this air motor is due to this fact solely 430W. The energy balance of an air motor is seen in a completely totally different gentle when you assume about that the air motor wanted for this packaging machine would only require a third of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of experience in the subject of air motors. They have a variety of high quality, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a particular answer for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our commonplace program has been adjusted to meet the needs of our prospects.
