Condition: ready for operation (used), functionality: fully functional, power: 23 kW (31.27 HP), input frequency: 50 Hz, overall weight: 2,850 kg, The Revent VC70A is a vacuum cooler specifically designed for bakery products, enabling very rapid cooling of bread and other products immediately after baking. Unlike traditional cooling on a trolley at ambient temperature or in a cold room, the VC70A creates a controlled vacuum inside the chamber. As the pressure decreases, a small portion of the moisture contained in the product evaporates at a low temperature. This evaporation rapidly removes the heat present in the core of the product, allowing for fast and uniform cooling. This technology therefore significantly reduces the time between the product exiting the oven and the subsequent production steps: slicing, packaging, freezing, or shipping. Revent also states that the process reduces the overall baking/cooling time while improving or preserving the volume, crumb structure, crust, and aromas of the product. It is suitable for both fully baked and pre-baked products. Key advantages: Gusdozy Nv Sjpfx An Ieg - Extremely rapid cooling of products after baking - Significant reduction in cooling time compared to traditional cooling - Possibility of reducing the time spent in the oven for certain products, as residual baking continues during the vacuum phase - Increased oven production capacity - Reduction in the number of trolleys and the space required for cooling - Uniform cooling to the core of the product - Better control before slicing or packaging - Preservation of the volume and structure of the bread - Improved quality of the crust and crumb - Reduced losses and rejected products - Suitable for industrial and semi-industrial production. Technical specifications – Revent VC70A Manufacturer: Revent International AB Model: VC70A Type: Vacuum Cooling System Maximum load: 70 kg per cycle Capacity: 1 trolley Maximum usable space: 820 × 1000 mm Configuration: 1 front door Vacuum pump: 22 kW Power supply: 400 V / 50 Hz / three-phase Rated current: 52 A For some products, the cooling time can be reduced to just a few minutes instead of several tens of minutes with a conventional method. The exact duration naturally depends on the product, its weight, its baking process, and the desired final temperature. In summary: The Revent VC70A is neither an oven nor a conventional cooling chamber. It is a process equipment that rapidly removes heat from the product using a vacuum. It is particularly interesting for industrial bakeries looking to increase oven throughput, shorten the production cycle, and package or process products much more quickly after baking. Machine available for inspection.

Condition: excellent (used), Year of construction: 2020, Ref: 11146 . 2020 Horizon RD-4055 Rotary Die Cut System Efficient production with separator and card stacker for labour saving operation. Features: • Die cutting, waste separation and stacking in one pass for efficient production. • A wide range of applications can be processed such as business cards, greeting cards, labels and light packages. • Maximum 6,000 sheets can be processed. • 21-up round corner business card production can processed at 126,000 cards per hour. Guedpfx Aoz Aklmsn Iog • Simple and easy operation without relying on a skilled operator. • Uniquely designed servo motor controlled ‘Repeat-cut’ feature allows multiple-up cuts from a single up die to minimize die cost. • Ruggedly constructed yet compact compared to normal die cutters. • Various delivery options are available to process a wide range of applications. • Die-cutting and Kiss cutting can be performed simultaneously by using a die which has two different blade heights, ideal for making stickers and labels. • Creasing can be achieved to avoid image cracking. Suitable for boxes, pocket folders and greeting cards which require additional folding processes after die cutting. • Repeat-cut enables the running of multiple up imposed applications with a smaller die to reduce die cost (Up to 8 repeats) Equipped with: TOUCH PANEL: Both setup and control can be done through the intuitive touch screen. After mounting the upper and lower die, the system can be set up by simply inputting sheet size and product size. The graphical illustrations on the screen are simple and easy to understand. FEED SECTION: Vacuum belt feeding enables superior feeding with easy setup and operation. An ultrasonic sensor is used for double feed detection on a wide range of substrates. The optional code reader BR-N4055 enables job separation for easy handling. TRANSPORT SECTION: Sheets are registered by vacuum belt and position is firmly secured with gripper rollers for accurate and consistent register. Servo motor driven gripper rollers ensure the die cut position without effecting processing speed. The optional alignment detection sensor ADS-N4055 detects the alignment error for additional quality control. DIE CUTTING SECTION: Rigid magnetic upper roller and solid lower anvil cylinder ensure high quality die cutting. Uniquely designed die cutting section enables easy and quick die setting.
