Description

[0001] SEMOLINA PURIFIER SIEVE

[0002] Technical Field

[0003] The invention relates to a semolina purifier sieve.

[0004] The invention particularly relates to a semolina purifier sieve in which rigid polyurethane suitable for dry food contact is used as the sieve frame material in order to eliminate the structural, hygienic and operational problems caused by wooden and aluminum frames used in existing techniques and also to increase the performance and efficiency of the sieving systems.

[0005] State of the Art

[0006] Semolina purifier is a sieving and separation device used in flour and semolina production facilities. Its main function is to increase the homogeneity and quality of the product by classifying particles of different sizes. The device usually consists of sieve systems and separates particles according to their size while also removing unwanted foreign materials and dust. This process allows the semolina to be classified into finer or thicker granulations. Semolina purifiers have mechanical systems that operate with vibrating or rotary movements and are designed to optimize the product flow in the production line. These devices are of critical importance to ensure high quality semolina production, especially after the grinding process.

[0007] The frames used in semolina purifiers are manufactured from durable and lightweight materials in order to increase the efficiency of the screening process and to ensure long- lasting use. The frames are generally made of materials such as wood, aluminum or stainless steel. While wooden frames have traditionally been preferred due to their flexibility and ability to absorb vibrations, aluminum and stainless steel frames are widely used in modern systems since they are more durable. However, these materials can create various technical and operational problems during use.

[0008] Wooden frames are subject to structural deterioration over time, such as breakage, deformation and swelling due to environmental humidity. This causes the frame to lose its functionality and causes interruptions in the system. Aluminum frames tend to oxidize, especially in humid and hot production environments. This oxidation both reduces the durability of the frame and puts the hygienic standards of the product at risk. Both types of materials require high labor costs in the production process, which creates a disadvantage in terms of economic sustainability. In addition, the frames used in existing systems usually have a fragmented assembly structure. This design creates a risk of parts breaking off and mixing into the product during operation and threats food safety.

[0009] The increase in frame weight depending on the material type increases the total energy consumption of the sieving system and increases operating costs. On the other hand, filling problems occur during the use of the sieve mesh and these fillings need to be cleaned. The cleaning brushes used in existing products cannot effectively clean the entire sieving area and this situation leads to hygiene problems and blockages in the system.

[0010] The size of the sieving area is a fundamental parameter that determines the capacity of the system, and in the present arts this area is limited to 4,5 mzin wooden frames and 5 m2in aluminum frames. However, by enlarging the sieving area, system performance can be increased, and production capacity can be improved.

[0011] As a result of the research carried out on the subject, application numbered TR2007 / 00027 has been found. Application numbered TR2007 / 00027 relates to the semolina purifier sieve system used in the cleaning and classification of the product and mixed semolina coming from the sieves in flour and semolina factories according to their size and smallness ratio and relates to the aluminum case profiles made of metal-based material so that the said sieve system is more resistant to shaking operations and does not deform easily.

[0012] As a result, due to the negativities described above and the inadequacy of existing solutions on the subject, it has become necessary to make a development in the relevant technical field.

[0013] Object of the Invention

[0014] The invention is inspired by the current situation and aims to solve the above-mentioned drawbacks.

[0015] The object of the invention is to eliminate the structural, hygienic and operational problems caused by wooden and aluminum frames used in the prior art, and at the same time to increase the performance and efficiency of sieving systems. The invention proposes the use of rigid polyurethane suitable for dry food contact as a sieve frame material. Polyurethane material will eliminate structural problems such as breakage, swelling and deformation experienced in wooden frames and oxidation problems encountered in aluminum frames, ensuring that the frames are hygienic and durable.

[0016] The lightness of the polyurethane material will contribute to saving energy consumption by reducing the total weight of the system. This offers a significant advantage in terms of both reducing operational costs and supporting environmental sustainability.

[0017] Unlike existing products, the invention aims to produce the main components of the cleaning mechanism in a monolithic structure with the frame. This design will allow the sieving area to be effectively cleaned on a larger surface and will prevent filling problems and ensure that hygiene standards are maintained. In addition, the monolithic structure of the components will reduce the number of parts used during assembly, thus minimizing the risk of parts breaking and mixing into the product.

[0018] By utilizing the engineering and design capabilities of the polyurethane material, the size of the sieving area will be increased, which will provide a significant improvement in the capacity of the system. A larger sieving area will optimize the efficiency of production lines while increasing volume.

[0019] As a result, this invention will provide superiority over present techniques in terms of durability, hygiene, energy efficiency and capacity increase by means of both material selection and design improvements.

[0021] • a body made of polyurethane material suitable for rigid dry food contact, with a hollow frame in the middle,

[0044] A Semolina purifier sieve Detailed Description of the Invention

[0045] In this detailed description, the preferred embodiments of the semolina purifier sieve (A) which is the subject of the invention are described only for a better understanding of the subject.

[0046] The semolina purifier sieve (A) which is the subject of the invention has been developed to be used by being fixed to semolina purifiers (9) which perform the sieving and separation processes in flour and semolina production facilities. The semolina purifier sieve (A) also starts to vibrate with the vibration drive of the semolina purifier (9). There are at least four semolina purifier sieves (A) in a semolina purifier (9) chamber, and in order to remove the semolina purifier sieve (A) from the chamber, the subsequent semolina purifier sieve (A) must be pulled.

[0047] The semolina purifier sieve (A) basically comprises a body (1) which acts as a main structure and elements connected to the body (1 ). The body (1) is made of rigid polyurethane material suitable for dry food contact and is in square or circular shape. The body (1 ) is made of polyurethane material, which reduces weight and increases hygiene. The middle of the body (1) is in the form of an empty frame. The upper surface of the frame edges is defined as the adhering surface (6) and the sieve mesh (10) (sieve net) that will perform the sieving process is adhered to the adhering surface (6) located on the upper side of the body (1 ). The adhering surface (6) provides the determination of the sieving area, and the cross-sectional area has been reduced compared to the prior art. Thus, the sieving area has been increased. In the invention, the width of the adhering surface (6) is at least 2 mm and at most 15 mm.

[0048] There is an internal rib (5) on each of the four corners of the body (1 ). The internal ribs (5) are in a radiused form and provide structural reinforcement of the body (1) against environmental forces. In addition, the internal ribs (5) ensure that the sieved product is collected in the middle area on the body (1 ) due to their form. A discharge outlet (8) is formed on each internal rib (5) and the product accumulations that may occur on the internal ribs (5) are discharged with the discharge outlets (8).

[0049] In the semolina purifier sieve (A) which is the subject of the invention, there is at least one guide shaft (2) fixed between the two opposite edges of the body (1 ). In the invention, there is a brush mechanism (3) which ensures the cleaning of the sieve mesh (10). The brush mechanism (3) moves freely on the guide shafts (2). Thus, the brush mechanism (3) can reach every point of the sieve mesh (10) and perform cleaning.

[0050] In the semolina purifier sieve (A) which is the subject of the invention, there is a direction changer protrusion (4) which is integrated with the body (1 ). The direction changer protrusion (4) enables the brush mechanism (3) to change direction during its movement.

[0051] Thus, the brush wires in the brush mechanism (3) are separated to the right and left.

[0052] In the semolina purifier sieve (A) according to the invention, there is a pulling bracket (7) on the outer surface of one side of the body (1). The pulling bracket (7) allows the semolina purifier sieve (A) to be removed from the semolina purifier (9) and the residual sieve body (1) to be pulled out.
