[0001] DESCRIPTION

[0002] MACHINE FOR PRODUCING FISH FEED IN POWDER FORM Technical Field of the Invention

[0003] The invention relates to a fish feed production machine having spraying and drying processes that enable the production of feed in powder form in suitable sizes and shapes for feeding aquarium fish, particularly small ornamental fish.

[0004] State of the Art

[0005] Fish feed is a specially formulated nutrient used for feeding fish in both natural and artificial aquatic environments. These feeds, developed to provide the basic nutrients required by fish, are presented in different forms (flake, granule, tablet, live feed, frozen feed, etc.) depending on the species, age, and specific requirements of the fish. The feeds prepared for aquarium fish, fish used in aquaculture, or fish living in natural environments play a critical role in ensuring healthy growth and development of fish. Fish feed helps fish grow healthily by ensuring balanced and adequate nutrition. Fish obtain all the nutrients they need in aquarium conditions or that are not available in their natural habitats through these feeds. A properly formulated feed ensures that fish receive essential nutrients such as proteins, fats, carbohydrates, vitamins, and minerals in balanced proportions. Balanced nutrition contributes to the resistance of fish against diseases and to their longevity.

[0006] Fish feed is also important in aesthetic terms, as it helps fish maintain their natural and vivid colours. This feature is particularly critical for aquarium fish and is achieved by means of special pigments contained in the feeds. In addition, fish feed is formulated with high protein content in order to increase reproductive performance. During the breeding period, the additional nutritional support required by fish is provided by means of fish feed. Providing a sufficient energy source enables fish to remain active and maintain their daily activities. Furthermore, fish feeds contain essential nutrients such as vitamins and minerals, strengthening the immune system of fish and making them more resistant to diseases. Properly formulated feeds are easy to digest and contribute significantly to maintaining water quality by reducing environmental pollution. Thus, fish feed has vital importance both for fish health and for the balance of the aquatic ecosystem. Various machines and processes are used to produce fish feed. Fish feed production is generally carried out for large fish, namely for use in cage aquaculture. These systems, which are of large dimensions, have complex structures and process procedures. These systems operate on the extruder principle, and by adjusting the sizing moulds and blades, the feed produced according to the type of fish varies in diameter between 2 mm and 12 mm. Systems designed for cage aquaculture cannot be used in the same way for aquarium fish. The sizes of the feeds produced in these systems are quite large and cannot be consumed by aquarium fish. In such cases, feeds produced for large fish are manually crushed into smaller sizes, that is, into powder form. However, these large feeds are reduced to powder form without considering the suitability of their ingredients for aquarium fish. Although crushing large feeds for aquarium fish is a correct approach in terms of consumption, the content of the feed produced for cage fish (protein, vitamin, fish oil, etc.) may not be suitable for aquarium fish.

[0007] Although various proposals and applications have been developed for fish feed production machines in the state of the art, these developments are not sufficient. Some applications concerning inventions developed for this purpose are given below. In the invention disclosed in the application numbered JPH04267852A in the prior art, the production of soft dry pellets with good palatability for fish, having a large diameter (>10 mm), and suitable for fish farming, is described as being achieved easily and with high efficiency. Adry pellet raw material for fish farming, mixed with starch, is combined with an expanding agent, fed into an extruder, the starch in the raw material is gelatinised, and the raw material is extruded through a die hole of the extruder having a diameter of >10 mm into the atmosphere, expanded and granulated, thereby producing large-diameter (>10 mm) dry pellets for fish farming.

[0008] The invention disclosed in the application numbered CN209331159U found in the prior art relates to a machine that enables the production of feed in larger sizes for mixed-culture fish. It is described that the products are mixed, passed through crushing rollers, and subsequently through cutting blades to obtain smaller sizes or powder form.

[0009] Fish feed production machines are found in the prior art. However, the fish feed production machines in the prior art remain inadequate due to reasons such as the production systems have high hourly production capacities, complex process operations, and large dimensions, which therefore require a large area for installation of the production machines; the feeds produced for large fish are not suitable for aquarium fish; there is no direct production offish feed in powder form; the large-sized fish feeds produced are reduced in size for aquarium fish by means of additional machines such as mincing or crushing machines; during the reduction process, feed losses occur; the feed reduction processes are complex and require a high amount of human labour; the content of feeds produced for large fish is not suitable for aquarium fish; the materials required for the feed content are weighed manually; deficiencies occur in the control of the feed content; errors arise in the mixing ratios due to the manual mixing of the feed mixture; unpleasant odours spread to the surroundings because the feed mixture mixing chamber is open at the top; and the feed mixture is either adequately or inadequately cooked.

[0010] As a result, due to the drawbacks mentioned above and the inadequacy of current solutions regarding the subject matter, a development in the relevant technical field has become necessary.

[0011] The Aim of the Invention

[0012] The most important aim of the invention is to enable the mixing, cooking, spraying, and drying processes of the feed mixture to be carried out in a single compact and portable machine. Thus, a large area is not required for the installation of the machine.

[0013] Another aim of the invention is to allow easy adjustment of the feed mixture spraying head. Thus, it becomes possible to produce feed in powder form in the desired sizes. Another aim of the invention is to ensure precise adjustment, with 2% accuracy, of the content suitable for the fish for which the feed will be produced, by means of an automation system. Thus, the feed content can be produced precisely and without error in accordance with the desired composition.

[0014] Another aim of the invention is to prepare the feed mixture in an enclosed chamber. Since all of the feed mixture materials are mixed in an enclosed chamber, the spread of unpleasant odours to the surroundings is prevented. Another aim of the invention is to perform the cooking process of the fish feed mixture by using hot steam under constant pressure to achieve a homogeneous mixture of the feed contents. Thus, the contents are cooked homogeneously.

[0043] Description of the Invention

[0044] The invention relates to a fish feed production machine having spraying and drying processes that enable the production of feed in powder form in suitable sizes and shapes for feeding aquarium fish, particularly small ornamental fish.

[0045] The invention mixes the products contained in the feed content while cooking them at a desired temperature value by means of an automation system, thereby bringing the feed mixture into a semi-liquid (boza / pudding-like) consistency. Subsequently, the continuously mixed feed mixture is sprayed onto a heated drying belt (13) by means of the nozzle head (16). The feeds dried on the drying belt (13) reach the packaging section at the end of the drying belt (13). During the drying stage of the feed mixtures, a high-pressure spraying method is used, which contributes to the reduction of feed size.

[0046] In general terms, the invention is designed in a modular structure that comprises all the processes required for feed production. The machine that is the subject of the invention produces aquarium fish feed in powder form within the desired size ranges. In the relevant machine, the raw material filling, weighing and mixing, liquid addition, spraying, and drying processes are all performed fully automatically by means of a user-controlled automation system.

[0047] By means of its pressurised spraying system (12), the invention provides the production of fish feed in powder form suitable for consumption by very small-sized fish. Since the machine system has an enclosed structure, no negative effects such as the spread of odour or steam to the environment occur. In addition, since all products are subjected to filling, weighing, and mixing processes within a single chamber during the mixing processes, the raw materials are mixed homogeneously, thereby effectively meeting the nutritional values required for feeding aquarium fish.

[0048] The invention comprises a chassis (1) made of pipes, on which all components of the machine are mounted; a filling hopper (2) which is a closed chamber of conical structure in which all solid and liquid ingredients required for the production offish feed in powder form are accumulated, mixed, and cooked, thereby ensuring that the fishfeed mixture is homogeneous and contributing to the flow system; a solid feed inlet (3) located on the filling hopper (2), which enables the solid raw-material ingredients required for fish feed production to be placed into the filling hopper (2), the inlet having an elliptical mouth and being inclined to facilitate a wide product flow; a liquid feed inlet (4) located on the filling hopper (2), which enables the liquid raw-material ingredients required for fish feed production to be placed into the filling hopper (2), the inlet being in the form of a pipe and having a connection flange at its upper part to allow the attachment of a special flow line as desired by the user; a hot steam line (5) made of insulated pipes and provided with a connection flange, which supplies steam to the system to enable the raw materials inside the filling hopper (2) to merge and to release the vitamins contained in the raw materials; a mixing auger (6) having a solid shaft at its centre and helical blades on its upper part, which ensures that all components inside the hopper are mixed homogeneously after steam is supplied to the system; a servo motor (7) of servo type, used to drive the mixing auger (6), whose rotational speed can be adjusted through the speed-control feature within the automation system; a load cell (8) positioned on the side parts of the filling hopper (2), which determines the weight of the products added to the filling hopper (2) and operates in integration with the automation system; a control unit (9) connected to the automation system, which automatically controls all components forming the system (such as the servo motor (7), load cell (8), and drying belt (13)) and is configured according to all features desired by the user; a vacuum pump (10) that provides vacuum to transfer the fish-feed mixture inside the filling hopper (2), which has been mixed into a liquid or paste-like consistency, to the spraying system (12); a transfer pipe (11) which, by means of the vacuum pump (10), transfers the fish-feed mixture in liquid or paste form from the filling hopper (2) to the collection unit (17) located at the upper part of the spraying system (12); a spraying system (12) comprising six nozzle heads (16) that spray the liquid or paste-like fish-feed mixture onto the drying belt (13) in very small sizes (in powder form); a collection unit (17) located at the upper part of the spraying system (12), which collects the liquid or paste-like fish-feed mixture coming from the filling hopper (2) and delivers it under pressure through a conical compression and spraying nozzle at the outlet part to spray it onto the drying belt (13); a nozzle head (16) which sprays, under pressure, the liquid or paste-like fish-feed mixture reaching the collection unit (17) at the upper part of the spraying system (12) onto the drying belt (13) through a conical compression and spraying nozzle situated at the outlet part, and on which nozzles with different micron sizes can be mounted as desired; a drying belt (13) which is a conveyor-belt system onto which the liquid or paste-like fish-feed mixture from the spraying system (12) is sprayed; a heating fan (14) which generates hot air for the closed drying system to dry the fish-feed mixture advancing on the drying belt (13) and blows the generated hot air into the closed drying system; and an upper belt cover (15) positioned above the drying belt (13), serving as insulation and ensuring that the hot air supplied to the system is retained within it.

[0049] The invention has a much smaller and more compact structure compared to systems that produce feed for large fish. With the reduction in system size, the production costs of the machine have decreased, the machine has been made portable, and the need for a large area for production has been reduced.

[0050] There are many types of aquarium fish. Depending on the content of the feeds consumed by fish, variations may occur in their colours and shapes. By means of the invention, the feed mixture is prepared in the filling hopper (2) by weighing the feed ingredients with 2% precision using the automation system. In addition, the temperature, pressure, and humidity values of all added components are continuously monitored by sensors, and when necessary, adjustments are made through the control unit (9) connected to the automation system, thereby ensuring that the fish-feed mixture is obtained at the desired values.

[0051] In the system, the control unit (9) connected to the automation system, which has been designed for the user to control the machine in the most effective way, includes the on-off and emergency stop buttons of the machine. In addition, the screen showing important parameters such as the weight of the products added to the system, the internal temperature of the filling hopper (2), and the internal temperature of the drying belt (13) system, is also located on the control unit (9). The speed-control button, by which the speed of the drying belt (13) is adjusted, is also located on the control unit (9). While the user provides the general control of the machine through the control unit (9) connected to the automation system, they can also adjust the system according to their own preferences.

[0052] The invention is designed as a modular system in a compact structure. The main structure of the system is formed by the chassis (1 ) made of 060 mm pipe. The chassis (1) is reinforced with intermediate supports and designed to carry the equipment mounted on it. At the beginning of the process, the section where the raw-material products and liquid additives are combined and mixed is the filling hopper (2). The filling system consists of the solid feed inlet (3), into which solid products such as fish meal are added; the liquid feed inlet (4) with a DN50 pipe, through which liquid additives can be added; and the hot steam line (5), through which hot steam is supplied for the cooking process of the mixture. The temperature of the mixture inside the filling hopper (2) is continuously monitored by the temperature sensors located in the filling hopper (2) through the control unit (9) connected to the automation system. The filling hopper (2) is continuously weighed in real time by means of two load cells (8) with a sensitivity of 0.001 kg. In addition, a mixing auger (6) is provided in the filling hopper (2) to ensure that the mixture inside becomes homogeneous. The mixing auger (6) is driven by the servo motor (7), which can be adjusted to the desired rotational speed. All sensors and electronic components in the system are monitored through the control unit (9).

[0053] In the invention, after the raw materials in the fish-feed formulation are added to the filling hopper (2), mixed, cooked, and weighed, they are transferred from the lower part of the filling hopper (2) to the spraying system (12) by means of a stainless-steel transfer pipe (11) using a blower-type vacuum pump (10) with high suction power. The fluid raw material transferred to the spraying system (12), which consists of six nozzle heads (16), is sprayed at high pressure onto the drying belt (13). The spraying heads (16) ensure that the liquid product coming from the filling hopper (2) is sprayed in powder form through its conical inner structure and specially designed outlet nozzle. The drying belt (13) maintains the drying section between the upper belt cover (15) and the drying belt (13) at a constant temperature by means of two resistance-type heating fans (14) operating at the desired temperature value. The material dried on the drying belt (13) is collected from the discharge outlet and / or optionally proceeds to the next process stage (the packaging system).

[0054] The invention provides an optimum raw-material mixture by means of a suitable cooking temperature and a simultaneous mixing process. These processes include a heating and mixing system. In addition, the nozzle system, through which the liquefied product is sprayed, is designed to be suitable for producing feed in powder form. Fish meal is added into the filling hopper (2) in the desired ratio. Then, vitamin additives are added according to the type of feed and the characteristics of the fish. Subsequently, a certain amount of water is added to the system in order to achieve the desired consistency. All components added to the system are introduced under the control of the user, depending on the feed content and formulation that the user wishes to create. Since there are aquarium fish species with different characteristics and structures, the determination of the appropriate feed content and the addition of the corresponding components to the system are entirely carried out according to the user’s preferences. After the materials required for feed production are added and the weighing process is completed, hot steam is automatically supplied to the system to initiate the cooking process, and the internal mixing auger (6) of the filling hopper (2) is operated by the servo motor (7) at an appropriate rotational speed according to the weight parameter and temperature value. The mixing auger (6) is driven by the servo motor (7) at a rotational speed automatically determined by the speed control located in the control unit (9) connected to the automation system, according to the system parameters. After the mixture has been stirred for a certain period of time and based on the data obtained from the sensors, the intermediate flap is opened and the vacuum pump (blower) (10) draws the fish-feed mixture from inside the filling hopper (2) through the suction pipe. The extracted fish-feed mixture is conveyed under high pressure through the transfer pipes (11 ) to the spraying head. In the spraying head (12), the fluid fish-feed mixture is sprayed onto the drying belt (13) through a suitable nozzle. The spraying process is continuously repeated according to the rotational speed of the drying belt (13). The spraying system (12) is located within a drying furnace. Here, hot air is blown into the system from both sides by means of two resistance-type heating fans (14). By means of this hot air, the feed mixture sprayed in liquid form is dried. At the end of the drying process, the fine and dried powdered feeds are transferred from the drying belt (13) to the relevant processes.

[0055] In the invention, the raw materials are cooked and mixed in proportions suitable for the formulation of the fish feed to be produced, ensuring that they are cooked while being mixed into a homogeneous structure. Thus, a homogeneous mixture is obtained. For fish feed production:

[0056] - Protein Sources: fish meal, shrimp meal.

[0057] - Vegetable and Animal Oils: canola oil, corn oil, and anchovy oil.

[0058] - Carbohydrates: plant-based carbohydrates such as wheat flour and com flour, which serve as binding agents for the fish feed.

[0059] - Vitamins and Minerals: vitamins A, D, E, K, C, and B, calcium, phosphorus, potassium, iron, magnesium, zinc, prebiotics, and probiotics can be used as raw materials.

[0060] The fish-feed mixture, having a pudding-like consistency, is sprayed onto the heated drying belt by means of the nozzle head in the spraying system (12). The spraying process ensures that the mixture spreads evenly over the surface. The sprayed fishfeed mixture is dried within a closed drying tunnel on a continuously operating conveyor drying belt (13). The drying of the fish-feed mixture is important for obtaining a product in powder form with the desired fineness and uniform shape. Before packaging, the product is dried in the drying system, making it ready for packaging. The produced fish feed is very small in size, ranging between 100 and 500 microns. The dried product, which reaches the appropriate parameters for consumption, is precisely weighed and packaged.

[0061] The machine for producing fish feed in powder form that is the subject of the invention occupies an area of 15 square metres. Therefore, it is a highly compact system that provides space efficiency. Since all processes required for feed production are gathered in a single machine, it provides advantages both in terms of installation space and operating cost.

[0062] The invention enables fish-feed production with a single machine. Efficient production is achieved by combining all the mixing, cooking, and drying processes within a single compact machine. The spraying process ensures that the fish feed produced is very small in size, ranging between 100 and 500 microns. With the pressurised nozzle heads used in the spraying system (12), products of geometrically consistent structure and identical properties are obtained. In this way, homogeneous production is achieved. By means of high-pressure spraying nozzles, the production of feed in powder form at very small sizes (100-500 microns) is achieved. In this way, the feed requirement of very small fish such as ornamental fish is met. When products with different micron sizes are desired, the diameter of the spraying nozzle head (16) can easily be changed, and fish feed can be produced in the desired sizes.

[0063] In the invention, the cooking process inside the filling hopper (2) can be controlled, and the cooking and mixing processes are carried out together. By performing the mixing and cooking processes within the same filling hopper (bunker) (2), the structural properties of the raw materials are fully transferred to the feed, and a homogeneous distribution is obtained. In addition, the drying process is performed within a closed-loop drying system containing a conveyor drying belt (13). The closed-loop drying system comprises the conveyor drying belt (13), the upper belt cover (15), and the heating fans (14). In this system, since spraying is carried out within the closed-loop drying system, the fish-feed mixture can be produced without being affected by external factors and without any deterioration in quality. While the product sprayed in powder form advances on the drying belt (13) within the closed-loop drying system, it is exposed to hot air, its moisture content is reduced, and it is brought into a consumable form. Since the conveyor drying belt (13) operates continuously, homogeneous drying is achieved, and product accumulation is prevented.

[0064] The invention ensures the healthy and balanced feeding of aquarium fish while increasing the efficiency of the production process. In this way, users obtain high-quality feed while also reducing costs and gaining a competitive advantage.
