Ensure top-notch reliability with the best drive for the job

Automated processes are commonplace practice within the food industry. Production efficiency just isn’t the one motivation, hygiene also performs a key role within the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss how to design a drive to satisfy these requirements and incorporate both these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the right drive is selected to fulfill the excessive requirements for hygiene within the food business, we normally recommend our ADVANCED LINE air vane motors. All their external components are made from chrome steel and are impervious to normal cleansing agents. The clean floor of these air motors is easy to wash. The drives are so well 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 proof against water penetration from generally used cleaning spray techniques. A wet setting 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 can be operated oil-free. A energy discount of approx. 10-20% based mostly on the technical data said within the product catalog ought to 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 functions, condensation can form in air provide strains. It is subsequently advisable that measures are taken to guarantee that the motor just isn’t situated on the lowest level within the system and that it can be flushed out with water. Many users take precautionary measures, not only referring to the format of the motor of their system, but in addition concerning the usage of water separators or dryers in front of the drive. If all this isn’t potential, then we advocate a special coating for those elements throughout the motor’s inside which are produced from stainless steel. This is as a result of there’s a restrict to the use of chrome steel for heavy obligation, high-speed internal elements. Insider -called CWL coating provides insensitivity to corrosion.
Question: Do you might have any examples of where your motors can be used in the meals industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals industry functions are infinite. I’ll describe a couple of purposes in more element, such as 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 at the speed of seven-hundred rpm.
We even have the ideal drive for high-torque requirements 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 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of 63 mm.
Another application could be found in grinding mills and conveying methods for grain processing. In this case, the major target is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly explosive environments. You will even find our motors used in the processing of meat, for instance in a semi-automatic meeting 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 subsequently a high-power air motor with compact design is ideally suited to this software.
Question: What advantages 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 main advantages is its excessive 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 dimension. This is especially important when utilizing a handheld system however in fact additionally for robotic methods the place the drive strikes with the robotic arm.
Heat also leaves the air motor chilly. In important settings, compressed air is an unproblematic supply of vitality – it does not evaluate to the hazards of electrical energy. The power output from the air motor over broad torque ranges is nearly constant. Air motors can due to this fact be optimally operated in a large field of fluctuating masses. There is not any downside with load being applied on the air motor till standstill, no damages are incurred. This means it is much less apt to stalling. After reduction of the load, it’ll run again instantly and any variety of successive occasions. Air motor energy could be adapted just by adjusting the working pressure. The pace is decreased easily by throttling the air volume. Throttling supply air is beneficial when torque must also be significantly decreased. Exhaust air throttling ought to be chosen to cut back speed without any serious affect on the torque.
Question: Air motors are often seen to be much less environment friendly in comparability with electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The effectivity of a drive always depends on the conditions of the applying. Let me use this example to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at decreased pace over a protracted time period to secure the packaging tape. Electric motors cannot be loaded over an extended period of time with out running the risk of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand high hundreds and consequently would need to 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 might select 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 near idle speed at 450 rpm under light load. The power required for this air motor is subsequently solely 430W. The energy steadiness of an air motor is seen in a totally different light when you consider that the air motor wanted for this packaging machine would solely require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on many years of expertise within the field of air motors. They have a extensive range of high of the range, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a particular resolution 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 clients benefit from long-established dependable drive options for the food business and medical know-how.
