Fresh and ready-to-eat salads, vegetable dishes, herbs, and freshly reduce fruit type a half of Gartenfrisch Jung GmbH’s product portfolio. The long-established firm has evolved into the German market chief for contemporary convenience products thanks to its quality and expertise. Since early 2019, the vacuum provide to its tray sealer packaging machines has been exceptionally energy-efficient following the installation of a central vacuum system by Busch Vacuum Solutions.
Gartenfrisch Jung produces its comfort meals in a contemporary facility in Jagsthausen, a town in the German state of Baden-Württemberg. To enable it to provide contemporary uncooked produce all yr round, the company has its personal growers in Germany and Portugal. Cultivation in two totally different climate zones ensures that the whole product vary may be equipped year-round, sold to finish users across Germany by way of supermarket chains and low cost shops. The ready-to-eat salads are packaged into bowls under the company’s own label, as well as for third celebration brands. Gartenfrisch Jung’s history dates back to 1795. What began out as a small piece of farmland has now remodeled into built-in, controlled growers of salads and vegetables and one other arm for processing these merchandise. As a family enterprise, Gartenfrisch Jung has been handed from one technology to the next ever since it started. The experience gained as a result has due to this fact grown steadily, resulting in the company’s successful development and a prime quality commonplace of its merchandise. Nowadays, Gartenfrisch Jung processes a hundred and twenty tonnes of uncooked meals daily. This is equal to handling 2,000 pallets, which are then delivered to customers by eighty refrigerated autos.
เกจวัดแรงดันเชื้อเพลิง -to-eat salad dishes (Fig. 1) are packaged on twelve packaging traces with tray sealer packaging machines. In the past, these packaging machines have been outfitted with one rotary vane vacuum pump each, although one machine had two vacuum pumps. These 13 vacuum pumps had been used to evacuate the trays to the required vacuum stage previous to sealing. A two-shift operation is in place on all twelve packaging strains. The vacuum pumps ran constantly all through these shifts, aside from during breaks. During a third shift, the manufacturing facilities are cleaned whereas all equipment is stationary.
Jochen Neff, who’s in control of expertise at Gartenfrisch Jung, was on the lookout for an alternative vacuum provide, as a result of the warmth radiated by the thirteen vacuum pumps was placing a pressure on the air conditioning system within the manufacturing facilities, which are cooled to between 5 and 6 levels Celsius. Furthermore, เกจวัดแรงดันน้ำ had an put in motor output of over 50 kilowatts. The vacuum specialists from Busch Vacuum Solutions analyzed the situation and recommended a centralized vacuum supply, which might be arrange in a non-air-conditioned room outdoors the production amenities.
Because Jung’s comfort merchandise have the perfect vacuum for packaging at a vacuum level of 400 millibars, Busch recommended utilizing MINK claw vacuum pumps. This kind of vacuum pump has the very best effectivity factor out of all mechanical vacuum pumps. This is a result of their contact-free operating precept, which implies that the moving elements contained in the vacuum pump do not are out there in contact with one another. In flip, no oil-based lubrication is required and all maintenance work related to the utilization of oil as an working fluid is eradicated.
Busch designed a vacuum system with three frequency-controlled MINK claw vacuum pumps (Fig. 2), each of which was outfitted with a motor with a nominal motor ranking of eight kilowatts. However, one of the three vacuum pumps is solely on stand-by. Nevertheless, the management system is programmed to guarantee that all three vacuum pumps have the same variety of working hours.
Centralizing the vacuum provide enabled the whole put in motor rating to be lowered from 50.2 to 16 kilowatts (Fig. 3) if we assume that two of the vacuum pumps run at 60 Hertz, i.e. most energy. This would correspond to a sixty eight percent reduction in energy consumption. However, in follow Jochen Neff has discovered that only one of many two MINK claw vacuum pumps is often in use and that this tends to run at a reduced rotational speed. After a quantity of months of use, Jochen Neff has measured common energy consumption of four kilowatt hours for the entire vacuum supply. This is mainly linked to the reality that the twelve packaging traces don’t all at all times run at maximum velocity and not the entire machines are in use on a regular basis. The demand-based management system then decreases the rotational pace to minimize back the output, meaning that the system solely provides the performance that is really required. In apply, this equates to energy financial savings of over 90 p.c for vacuum technology.
The new centralized vacuum system was put in in April 2019 and has been in use every since. It is related to the packaging machines by way of a network of pipelines. Two upstream vacuum vessels with a quantity of 1,500 liters every make positive that the required vacuum stage is available within the packaging chambers as soon as it is needed in the packaging cycle. Removing the 13 unique vacuum pumps from the manufacturing areas relieved pressure from the air-con system. This meant that the air con system could be turned right down to hold the room temperature between 5 and 6 levels Celsius. The financial savings in energy prices as a outcome of decreasing the air con output have not been measured. However, it might possibly typically be assumed that the change resulted in a big reduction within the energy consumed by the air con system.
Thanks to the vacuum system’s redundant design, maintenance could be carried out on the individual MINK claw vacuum pumps throughout production and packaging. MINK claw vacuum pumps are practically maintenance-free. Maintenance is restricted mainly to the annual preventive change in gear oil. This is carried out by a Busch service technician. With the centralized vacuum system, Jochen Neff has created a extremely energy-efficient, dependable and economical vacuum provide for packaging his convenience products.
