Automated processes are normal practice in the food industry. Production effectivity is not the only motivation, hygiene additionally performs a key function within the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to meet these requirements and incorporate each these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is selected to satisfy the excessive requirements for hygiene within the food trade, we often advocate our ADVANCED LINE air vane motors. All their exterior components are produced from chrome steel and are impervious to regular cleansing agents. The smooth surface of these air motors is straightforward to scrub. The drives are so well 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 immune to water penetration from generally used cleaning spray techniques. A moist environment is not any concern for this motor. It can even be used underwater as within the case of many stirring functions. pressure gauge ไท วัสดุ are lubricated with meals grade USDA-H1 grease and could be operated oil-free. A power discount of approx. 10-20% based on the technical data said within the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor must boast different features for such applications?
Answer: Yes. In many purposes, condensation can type in air supply strains. It is due to this fact advisable that measures are taken to guarantee that the motor isn’t positioned at the lowest level within the system and that it may be flushed out with water. Many customers take precautionary measures, not solely relating to the layout of the motor in their system, but in addition concerning the utilization of water separators or dryers in entrance of the drive. If all this isn’t attainable, then we suggest a particular coating for those parts throughout the motor’s interior that are created from stainless-steel. This is because there is a restrict to the use of stainless-steel for heavy responsibility, high-speed inner elements. 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 food industry?
Answer: Stirring dough, transferring and slicing sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business functions are endless. I’ll describe a couple of functions in more detail, similar to the usage 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 seven-hundred rpm.
We also have the best drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of areas. The 900W high-torque motor with a nominal pace of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of 63 mm.
Another utility may be present in grinding mills and conveying methods for grain processing. In this case, the main target is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in doubtlessly explosive environments. You will even find 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 picket skewer by way of items 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 software.
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 only a fifth of the mass of an electric motor, or a 3rd of its measurement. This is particularly vital when using a handheld gadget however of course additionally for robotic systems the place the drive moves with the robot arm.
Heat additionally leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of vitality – it doesn’t examine to the risks of electricity. The power output from the air motor over wide torque ranges is kind of fixed. Air motors can due to this fact be optimally operated in a large area of fluctuating loads. There is not any problem with load being utilized on the air motor till standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it’ll run once more instantly and any variety of successive occasions. Air motor power can be adapted just by adjusting the operating strain. The velocity is decreased smoothly by throttling the air volume. Throttling supply air is beneficial when torque should also be considerably reduced. Exhaust air throttling must be chosen to scale back pace without any critical influence on the torque.
Question: Air motors are sometimes seen to be much less efficient compared to electrical motors. Can หลักการทํางานของpressuregauge touch upon this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The efficiency of a drive at all times is dependent upon the circumstances of the applying. Let me use this example to clarify: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at lowered pace over a long period of time to safe the packaging tape. Electric motors cannot be loaded over a long time period with out running the risk of overheating. Therefore, for this packaging machine, an electrical motor would need to withstand high masses and consequently would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally totally 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 velocity of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs close to idle speed at 450 rpm under gentle load. The energy required for this air motor is subsequently only 430W. The vitality stability of an air motor is seen in a completely different gentle when you consider that the air motor needed for this packaging machine would solely require a third of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on a long time of expertise in the field of air motors. They have a broad range of excessive quality, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a special answer 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 commonplace program has been adjusted to fulfill the wants of our customers.
