HYGIENIC DESIGN, RELIABLE SCREENING

Flour Sifter solutions,In line sifter for large capacities at small screen mesh sizes and accurate sieving. Can be used in vacuum  or pressure  conveying systems.


Where are protective screens used?

Protective screens are always used if the safety of the production process or the quality of a product could be endangered by an impurity. Protective screens can therefore theoretically be used at every stage of the process, but there are some typical applications


For the delivery of raw materials and before product storage
Many businesses have their bulk goods delivered by tanker or silo vehicle. So, while the product is being emptied and, for example, put in temporary storage in silos, screens on the tanker can be used for protective screening. These can easily be installed in the vehicle’s conveyor pipe and ensure that contaminants and impurities don’t make it as far as the silos, let alone the production process. Protective screening makes sense at this stage if the product is to be placed in interim storage for a long time so that no biological impurities can spread, for example.

Before the use of raw materials in the production process

Screens placed at this stage serve as protection for the downstream production machinery. They also contribute to a consistent product quality, as many bulk goods cease to be easy to process if they are not of an adequate quality. In this case, protective screening frequently occurs directly after discharge from the silo. As many bulk materials are prone to agglomeration if stored for a long time, protective screening makes sense even if the product was already screened before storage. The agglomerates created are separated by a protective screen after discharge from the silo, and light clumps are even dissolved by the screening.

Often, the raw materials aren’t placed in interim storage but removed immediately from their transport containers, e.g. Big Bags, and fed straight into the production process. In these cases, Engelsmann protective screens can even be integrated directly into the emptying station. This saves valuable installation surface area.

Before packaging the merchandise
It should be ensured that the product is free of all unwanted elements at the latest before the product is packaged or bottled for sale or internal processing. Undetected left-over impurities have a direct effect on the quality of the final product and can, at worst, entail complaints or product recalls.

Why is a protective screen important?
Reliability
As protective screens are usually permanently integrated into the production process, a defective machine can quickly lead to stoppages in production. If a protective screen is used as the “last line of defense” before packaging, production will, at worst, come to a standStill when the protective screening machine breaks down as the quality of the final product can no longer be guaranteed. Engelsmann therefore relies on long laSting machines of a solid construction (made from stainless steel as standard). To avoid downtime, we also emphasize low maintenance constructions with few parts subject to wear.

Throughput performance

If protective screening is implemented before the material feed in the production process, the productivity of the downstream processes depends greatly on what level of throughput the screen attains. If the screen does not achieve the required throughput performance, not enough material will be available for production. The throughput performance of a protective screening machine must be precisely coordinated with the production process so that the right quantity is available at the right time. At businesses where large quantities of bulk goods are processed, protective screens with high throughput performance are often in demand. Therefore, Engelsmann offers various models of protective screens with different throughput performance levels.

HOW DOES SILO SIFTER WORK?


Generally, solid fluids that come in bulk with silobus must be subjected to a control and separation before entering the process.
This is especially important for food processes (flour, sugar). Thus, foreign substances are separated and as a result of this separation, they become ready for use.
One of the types of sieves we have produced is the silobas control sieve for such processes.
While transferring with the help of high pressure (1.00-1.50bar), the product is separated from foreign substances with the help of vibration. All parts that come into contact with the product are certified according to regulation (EU) 1935/2004 or regulation.

Although the sieve is designed to work under pressure, it can also be used in vacuum processes.

We also apply vibration and conical pneumatic screening technologies in your pneumatic transfer processes and silobuses. Thanks to the conical screens in the range of our products which are installed at the highest level of the silos, we prevent ingress of foreign objects into your silos. Foreign materials especially sand, calcite and similar materials in the construction chemicals may give damage to the screws and mixers, other transport equipment of the process. For this reason, the raw material introduced in the process should be screened definitely.
Sieving - Maximum control for optimal results
Companies in the food, feed, pharma and chemical industries are being confronted with increasingly stringent requirements with regard to food safety, quality, tracking & tracing and hazards associated with dust and explosions. So it should come as no surprise that Dinnissen Process Technology is continually searching for the best solutions when it comes to quickly and reliably managing various granulated as well as powdered materials. Effi cient fractionation ensures the highest purity Our sieving technique is based on the use of our centrifugal sieves. The material to be fractionated is brought into the sieving
chamber, where the material is agitated by spinning fi ns. Those fractions which consist of small enough particles pass through the centrifugal sieve, whereas contaminants and larger particles are quickly transported onwards. By varying the rotation speed as well as the diameter of the openings and the path length of the sieve, we can realize any desired sieving result. And our broad range of
accessories and options makes it possible to realize the necessary level of quality, safety and hygiene for any situation.

HYGENIC DESIGN SIEVE

The machine housing and the screens are completely made of stainless steel. A new tangential inlet without screws prevents product from accumulating in the inlet. This makes the inline check sieve the perfect choice for use in the finished product section.

SPECIAL DESIGN SIEVE

The mobile screen is connected between the tanker truck and the silo-loading line using quick-change couplings. Pneumatic conveying can now be started.

The vibratory flatbed screener gently control screens the material with minimum particle degradation. The screen mesh width can be chosen according to the material to be screened. Fine particles surpass the screen, impurities remain on the screen.

After finished operation, the screen can be easily cleaned off by simply tilting up the entire top of the machine, either manually or using a vacuum cleaner.
