Enormous Energy Savings for Packaging Process

Fresh and ready-to-eat salads, vegetable dishes, herbs, and freshly minimize fruit type part of Gartenfrisch Jung GmbH’s product portfolio. The long-established firm has evolved into the German market leader for recent comfort products because of its high quality and experience. Since early 2019, the vacuum provide to its tray sealer packaging machines has been exceptionally energy-efficient following the set up of a central vacuum system by Busch Vacuum Solutions.
Gartenfrisch Jung produces its convenience meals in a modern facility in Jagsthausen, a city within the German state of Baden-Württemberg. To enable it to provide recent raw produce all year spherical, the corporate has its own growers in Germany and Portugal. Cultivation in two different climate zones ensures that the complete product range could be equipped year-round, offered to end customers across Germany by way of supermarket chains and discount stores. The ready-to-eat salads are packaged into bowls beneath the company’s own label, in addition to for third get together brands. Gartenfrisch Jung’s history dates again to 1795. What started out as a small piece of farmland has now transformed into integrated, controlled growers of salads and vegetables and another arm for processing these merchandise. As a family business, Gartenfrisch Jung has been handed from one era to the following ever since it started. The expertise gained consequently has subsequently grown steadily, resulting in the company’s successful improvement and a high quality commonplace of its merchandise. Nowadays, Gartenfrisch Jung processes 120 tonnes of uncooked food every single day. This is equivalent to dealing with 2,000 pallets, which are then delivered to prospects by eighty refrigerated autos.
The ready-to-eat salad dishes (Fig. 1) are packaged on twelve packaging lines with tray sealer packaging machines. In pressure gauge 4 นิ้ว ราคา , these packaging machines were geared up with one rotary vane vacuum pump each, though one machine had two vacuum pumps. These 13 vacuum pumps have been used to evacuate the trays to the required vacuum level prior to sealing. เกจวัดแรงดันน้ำประปา -shift operation is in place on all twelve packaging traces. The vacuum pumps ran constantly throughout these shifts, other than during breaks. During a 3rd shift, the manufacturing amenities are cleaned while all machinery is stationary.
Jochen Neff, who’s in command of expertise at Gartenfrisch Jung, was in search of an alternative vacuum provide, as a result of the heat radiated by the thirteen vacuum pumps was placing a strain on the air con system in the manufacturing services, which are cooled to between 5 and 6 levels Celsius. Furthermore, the vacuum pumps had an installed motor output of over 50 kilowatts. The vacuum experts from Busch Vacuum Solutions analyzed the situation and really helpful a centralized vacuum supply, which could presumably be set up in a non-air-conditioned room exterior the manufacturing amenities.
Because Jung’s comfort merchandise have the best vacuum for packaging at a vacuum degree of four hundred millibars, Busch really helpful utilizing MINK claw vacuum pumps. This kind of vacuum pump has the best effectivity issue out of all mechanical vacuum pumps. This is a result of their contact-free operating precept, which implies that the moving components contained in the vacuum pump do not are available contact with each other. In flip, no oil-based lubrication is required and all maintenance work associated to the usage of oil as an working fluid is eliminated.
Busch designed a vacuum system with three frequency-controlled MINK claw vacuum pumps (Fig. 2), each of which was geared up with a motor with a nominal motor score of eight kilowatts. However, one of the three vacuum pumps is completely on stand-by. Nevertheless, the management system is programmed to ensure that all three vacuum pumps have the identical number of working hours.
Centralizing the vacuum supply enabled the entire put in motor score to be lowered from 50.2 to sixteen kilowatts (Fig. 3) if we assume that two of the vacuum pumps run at 60 Hertz, i.e. maximum energy. This would correspond to a sixty eight % reduction in energy consumption. However, in follow Jochen Neff has found that only one of the two MINK claw vacuum pumps is often in use and that this tends to run at a decreased rotational pace. After several months of use, Jochen Neff has measured average power consumption of 4 kilowatt hours for the complete vacuum supply. This is principally linked to the reality that the twelve packaging traces don’t all always run at most speed and not the entire machines are in use all the time. The demand-based control system then decreases the rotational velocity to reduce the output, meaning that the system solely offers the performance that’s really required. In practice, this equates to power financial savings of over ninety percent for vacuum era.
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 via a network of pipelines. Two upstream vacuum vessels with a quantity of 1,500 liters every ensure that the required vacuum stage is on the market in the packaging chambers as soon as it’s needed within the packaging cycle. Removing the thirteen unique vacuum pumps from the production areas relieved pressure from the air-con system. This meant that the air-con system could probably be turned all the way down to hold the room temperature between 5 and 6 levels Celsius. The savings in vitality prices on account of lowering the air con output have not been measured. However, it can typically be assumed that the change resulted in a big reduction within the vitality consumed by the air con system.
Thanks to the vacuum system’s redundant design, upkeep can be carried out on the individual MINK claw vacuum pumps during production and packaging. MINK claw vacuum pumps are nearly maintenance-free. Maintenance is limited 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 supply for packaging his comfort products.
