During the production or rework of chocolate, the use of a control screening machine is an important part of the process. This ensures that there are no foreign parts or impurities in the chocolate mass. It is important that the chocolate does not cool down during the entire process and also during the screening process. A constant temperature of approx. 40°C must be maintained during production to ensure the gloss and high quality of the end product. For this application the GKM control screening machine type KTS-VS2 has been further developed. This screening machine is equipped with a double-walled cone through which water with a temperature of 35 - 65°C is permanently circulated to ensure continuous screening of the viscous chocolate mass. Of course, the machine can be equipped with other important features and characteristics for this kind of industry as: A motor support made of stainless steel 1.4301, all kind of food-grade surfaces, etc.. The control screening

More information about our capacitive Solution Capanivo® CN 7 The video shows solutions for difficult challenges. Capanivo® level switches can be used in many bulk solids and liquids as full, demand or empty indicators. The robust probe made of glass fibre reinforced plastic PPS is even suitable for food and resistant to many aggressive media. The Capanivo® can be used in storage and process vessels or in pipes as level switch and backwater detector.

To reduce the noise emission of your screening machine RHEWUM now offers an innovative sound insulation cover. Usually screening machines are not the quietest machines in the production chain. Due to impact bar movements the screen cloth is excited to high frequency vibrations. This, in combination with the product to be screened, causes noise emissions which sometimes have to be reduced. The sound insulation tarpaulin for screening machines provides a quick and uncomplicated solution to this problem. The sturdy, custom-made tarpaulin is covered with an acoustic membrane which damps the sound and absorbs sound energy. The sound power level of the machine can be reduced by 8 dB by attaching the sound-insulating tarpaulin, which corresponds to approximately halving the perceived noise level. The tarpaulin is flexible and easy to bend - which in turn ensures simple and quick installation on the machine. Important maintenance openings remain easy to operate, as the tarpaulin can be opened at the crucial points using robust zips. The short implementation time and the cost-effective

Sesotec’s Flake scan analysis system saves time and money Schönberg, August 2020 The quality of plastic flakes and regrind is crucial in determining whether plastic processors and manufacturers can profitably use and sell plastic recyclate. Depending on how the recyclate will be used, elaborate manual, visual, or thermal sample analyses are often necessary in order to assess the quality of a batch of materials. Sample analyses are also used as a means of evaluating the effectiveness of the recycling sorting process. Such sample analyses are hardly representative, and furthermore require additional resources, costs, and time. Flake scan by Sesotec was developed to help reduce the effort involved in various analysis techniques. In just a few minutes, the device can reliably determine the precise quality of plastic flakes and regrind. The Flake scan analysis system delivers data that can be quickly leveraged to make decisions about whether plastic flakes and regrind are pure enough for profitable use. It can also provide

Screen your ammonium nitrate safely and without risk by using RHEWUM screening technology. Ammonium nitrate is considered to be oxidizing but cannot ignite itself - unless large quantities are close together. Then it starts to work and heats up. The ammonium nitrate catches fire. This releases oxygen and the fire spreads. In fertilizers, it may only be used in mixtures due to its latent danger. But what does this mean for screening? Possible risks that could arise during a screening process of ammonium nitrate are, for example, high dust generation, which can lead to dust explosions and damage to health. In conformity with the ATEX directives RHEWUM screening machines are equipped with a dust-tight housing with connection to a dust extraction system to avoid high dust concentrations. A further risk is the required vibration during screening. All moving parts of a screening machine (e.g. the excitation axles, springs or bouncing balls for cleaning the meshes) which come into contact with ammonium nitrate can potentially cause an effective force. This friction

French animal feed manufacturer gets suitable RHEWUM screening machine for screening of meat and bone meal. Animal meal is often added to animal feed as a source of protein and used as food for pets as well as zoo animals. Under strict conditions, it is also suitable as a fertilizer in agriculture. For the feed capacity of 20 tons of animal feed per hour the customer now receives a screening machine type WA with suitable feeder type SV from RHEWUM which replaces an outdated screening machine of another screening machine manufacturer. The separation is at 1 mm for removing lumps and impurities. The type WA is excellently suited for sieving powder and meal in the finest to medium grain range and can be easily integrated into existing plants. The direct transmission of the vibrations to the screen mesh via powerful electromagnets is not only energy-efficient, but also enables extremely high accelerations of more than 15 g and thus guarantees a sharp separation even when screening fine powders. Further convincing advantages of the Rhewum wa are the high availability and reliability.
