Automated processes are standard apply in the meals trade. เกจวัดแรงดันเชื้อเพลิง isn’t the one motivation, hygiene also performs a key function in the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to fulfill 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 best drive is chosen to fulfill the high requirements for hygiene in the food industry, we normally suggest our ADVANCED LINE air vane motors. All their external components are created from chrome steel and are impervious to normal cleansing agents. The smooth surface of those air motors is easy to scrub. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no dust, water or different solutions can penetrate the motor. The motors are even resistant to water penetration from generally used cleaning spray techniques. A moist 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 food grade USDA-H1 grease and can be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical data acknowledged 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 purposes, condensation can form in air provide strains. It is subsequently advisable that measures are taken to guarantee that the motor is not positioned at the lowest point 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 additionally concerning the utilization of water separators or dryers in front of the drive. If all this isn’t possible, then we advocate a special coating for those components inside the motor’s interior which are created from chrome steel. This is as a outcome of there is a restrict to using stainless steel for heavy duty, high-speed inner components. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be used within the food industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are endless. I’ll describe a quantity of functions in additional 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 pace 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 energy in 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 sixty three mm.
Another application may be present in grinding mills and conveying methods for grain processing. In this case, the main target is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably explosive environments. You will even find our motors used within the processing of meat, for example 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 wooden 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 software.
Question: What advantages does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the main advantages is its high power 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 important when utilizing a handheld device however of course also for robotic systems where the drive moves with the robot arm.
Heat also leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of power – it does not examine to the hazards of electrical energy. The energy output from the air motor over broad torque ranges is nearly constant. Air motors can subsequently be optimally operated in a large subject of fluctuating hundreds. There is no drawback with load being applied on the air motor till standstill, no damages are incurred. This means it is less apt to stalling. After reduction of the load, it will run again immediately and any variety of successive instances. Air motor power could be adapted just by adjusting the operating stress. The velocity is decreased easily by throttling the air quantity. Throttling provide air is recommended when torque also wants to be significantly lowered. Exhaust air throttling ought to be chosen to minimize back velocity without any serious affect on the torque.
Question: Air motors are often seen to be much less efficient compared to electric motors. Can you comment on this statement?
Answer: Air motors and electrical motors cannot be compared on a one-to-one foundation. The effectivity of a drive all the time is decided by the conditions of the application. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at lowered pace over a protracted time frame to safe the packaging tape. Electric motors can’t be loaded over a protracted time frame with out working the chance of overheating. Therefore, for this packaging machine, an electric motor would need to face up to excessive masses and in consequence would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very totally different story with the air motor: Due to the favourable torque characteristics of air motors, a lower-powered drive will suffice. You might select an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs near idle velocity at 450 rpm under light load. The energy required for this air motor is due to this fact solely 430W. The vitality steadiness of an air motor is seen in a totally totally different mild when you consider that the air motor wanted for this packaging machine would only require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of experience in the field of air motors. They have a extensive range of high quality, globally popular industrial drive options. Are the ADVANCED LINE motors a special resolution for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our standard program has been adjusted to meet the wants of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients profit from long-established dependable drive options for the meals business and medical technology.
