Fresh and ready-to-eat salads, vegetable dishes, herbs, and freshly minimize fruit form a half of Gartenfrisch Jung GmbH’s product portfolio. The long-established company has advanced into the German market chief for contemporary comfort merchandise due 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 foods in a modern facility in Jagsthausen, a city within the German state of Baden-Württemberg. To enable it to supply contemporary uncooked produce all year round, the corporate has its personal growers in Germany and Portugal. Cultivation in two different climate zones ensures that the complete product vary could be supplied year-round, bought to end users across Germany through grocery store chains and low cost stores. The ready-to-eat salads are packaged into bowls beneath the company’s personal label, as properly as for third party manufacturers. Gartenfrisch Jung’s historical past dates again to 1795. What started out as a small piece of farmland has now transformed into built-in, managed growers of salads and vegetables and one other arm for processing these merchandise. As เพรสเชอร์เกจnuovafima , Gartenfrisch Jung has been passed from one era to the next ever since it started. The experience gained as a result has due to this fact grown steadily, leading to the company’s profitable growth and a top quality standard of its merchandise. Nowadays, Gartenfrisch Jung processes 120 tonnes of raw meals every single day. This is equal to handling 2,000 pallets, which are then delivered to customers by 80 refrigerated automobiles.
The ready-to-eat salad dishes (Fig. 1) are packaged on twelve packaging lines with tray sealer packaging machines. In the past, these packaging machines had been geared up with one rotary vane vacuum pump every, although one machine had two vacuum pumps. pressure gauge ยี่ห้อ tk were used to evacuate the trays to the required vacuum degree prior to sealing. A two-shift operation is in place on all twelve packaging lines. The vacuum pumps ran continuously all through these shifts, aside from during breaks. During a third shift, the manufacturing amenities are cleaned whereas all machinery is stationary.
Jochen Neff, who is in cost of expertise at Gartenfrisch Jung, was looking for another vacuum supply, as a outcome of the heat radiated by the thirteen vacuum pumps was placing a strain on the air conditioning system in the production amenities, which are cooled to between 5 and 6 degrees Celsius. Furthermore, the vacuum pumps had an put in motor output of over 50 kilowatts. The vacuum experts from Busch Vacuum Solutions analyzed the situation and beneficial a centralized vacuum provide, which could possibly be set up in a non-air-conditioned room outdoors the production facilities.
Because Jung’s comfort products have the perfect vacuum for packaging at a vacuum level of four hundred millibars, Busch really helpful utilizing MINK claw vacuum pumps. This type of vacuum pump has the very best effectivity issue out of all mechanical vacuum pumps. This is a results of their contact-free working precept, which means that the shifting parts inside the vacuum pump don’t are available contact with each other. In turn, no oil-based lubrication is required and all upkeep work related to the utilization of oil as an operating fluid is eliminated.
Busch designed a vacuum system with three frequency-controlled MINK claw vacuum pumps (Fig. 2), every of which was equipped with a motor with a nominal motor score of 8 kilowatts. However, one of the three vacuum pumps is exclusively on stand-by. Nevertheless, the management system is programmed to make certain that all three vacuum pumps have the identical variety of working hours.
Centralizing the vacuum supply enabled the whole put in motor score to be decreased from 50.2 to 16 kilowatts (Fig. 3) if we assume that two of the vacuum pumps run at 60 Hertz, i.e. maximum power. This would correspond to a 68 p.c reduction in vitality 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 lowered rotational pace. After a number of months of use, Jochen Neff has measured common power consumption of 4 kilowatt hours for the complete vacuum supply. This is principally linked to the reality that the twelve packaging strains do not all at all times run at maximum speed and never all of the machines are in use on a regular basis. The demand-based management system then decreases the rotational velocity to scale back the output, that means that the system only provides the performance that is truly required. In follow, this equates to energy financial savings of over 90 % for vacuum technology.
The new centralized vacuum system was put in in April 2019 and has been in use every since. It is linked to the packaging machines by way of a network of pipelines. Two upstream vacuum vessels with a volume of 1,500 liters every make sure that the required vacuum degree is out there in the packaging chambers as soon as it is needed within the packaging cycle. Removing the 13 original vacuum pumps from the production areas relieved pressure from the air conditioning system. This meant that the air-con system could possibly be turned all the way down to maintain the room temperature between 5 and 6 degrees Celsius. The savings in energy costs on account of reducing the air conditioning output have not been measured. However, it could generally be assumed that the change resulted in a significant discount in the power consumed by the air conditioning system.
Thanks to the vacuum system’s redundant design, maintenance may 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.
