Abstract

FIELD: food industry. SUBSTANCE: method involves supply of source solution, in the process of formation of grains, into liquid that is in the state of uniform rotation. The solution is supplied through one or several holes. The holes are 3-5 mm in diameter. The grains are transported by gravity through valves, and the processes of cooling and separation of the grains from the liquid are concurrent with the process of drain of the grain-and-oil mixture into a vessel with cooled water. The water in the vessel is also stirred to rotate. The device for implementation of this method has a vessel divided into two parts: the upper part for formation of caviar grains and the lower part. The latter cools the grains and separates them from oil. Both are provided with electric-driven stirrers. The stirrers are vanes mounted in the center of each vat for rotation. They are also provided with transport valves, and the lower one is provide with a valve for drain of oil. The valve is mounted level with the "forming liquid-water", and the vat for the source solution is an open funnel with one or several outlets 3-5 mm in diameter. They provide communication between the funnel and vat. The funnel has several isolated compartments, and one of them is used for filling. EFFECT: simpler method; higher rate of process. 7 cl, 1 dwg, 1 tbl

Description

 The invention relates to the food industry and can be used for the manufacture of spherical grains from food products, in particular for the production of simulated black granular caviar.

 Known methods for the manufacture of simulated fish grain caviar [1, 2] include the preparation of the initial solution from the filler and gelatinous substance, filtering it, forming spherical grains by injection of the initial solution by the pressure of compressed gas into the air gap or directly into the forming liquid located in the tank in stationary state, through metered calibrated holes of small diameter (≈ 0.3 mm), moved in a circle, further cooling of the formed grains, transportation and through a special conduit gear pump or pressure forming the liquid column, separating the beads from the oil, their coloration, washing, salting and flavoring ingredients.

 Devices for implementing these methods for the manufacture of caviar [3] include a thermostatic sealed container for the initial solution, a container with a forming liquid in the form of a narrow vessel equipped with a cooling jacket with a receiving funnel with a heating element in the upper part, and devices for squeezing the initial solution from the container into in the form of a gear pump with a pipeline or a cylinder with compressed gas, a device for the formation of metered droplets of the initial solution and their spraying relatively VISION-forming liquid, grain storage, container for washing the grains from the oil, and the device with conduits for transporting grain.

 The disadvantages of the known methods for the manufacture of fish granular caviar and devices for forming spherical grains are low productivity due to the small outlet for the initial solution, the unstable mode of grain formation, causing a different grain size, i.e., a significant amount of marriage, large dimensions of the devices, the complexity of the process grain formation and device design (pumps, compressed gas cylinders, cooling shirts, transportation devices, etc.), high complexity the operation process of the plants and, as a result, the high cost of the finished product.

 The ones chosen as prototypes are distinguished by a higher technical level: a method for manufacturing simulated black granular caviar from natural products [4] and a device for forming spherical grains from food products [5].

 This method includes the preparation of the initial solution from the filler and the gel-forming substance, the subsequent heating of the solution and its filtration without the use of pressure sources, the formation of spherical grains by squeezing the initial solution from a sealed thermostatically controlled container with a slight pressure of compressed air through calibrated openings into a container with heated in the upper part air layer and forming fluid - vegetable oil, cooling grains in oil and water, transporting their column m liquid forming and separating the grains from the oil, followed by coloring, washing, salting and flavoring dressing.

 A device for implementing this method comprises a sealed supply container with a thermostatic jacket connected to a source of compressed air, a cylindrical vessel with a receiving funnel, a heating element and cooling jackets, between which an annular gap for forming liquid is formed, nozzles placed above the funnel and fixed on the bottom rotary supply container having at least two outlet openings in communication with the supply capacity, a sealed drive a new container enclosed in a cooling jacket and having a pipeline placed therein for transporting grains, a pipeline for maintaining the working level in the funnel of the forming container.

 The disadvantages of the data of the method and device are low (3-10 kg / h) productivity and high complexity of both the process of grain formation and the manufacture and operation of the device. The complexity of the device is due to the presence of a large number of cooling jackets, sealed thermostatic containers, a pressure source, a device for dispensing and spraying drops of the initial solution, transport pipelines. The performance of the installation is limited by the finite number of outlet openings and their small diameter (0.3 mm).

 The aim of the invention is to simplify the method, the intensification of the process and the reduction of its complexity.

 The goal is achieved in that the process of grain formation consists in the formation of metered drops of the initial solution and spraying them into a stationary forming liquid (or an air gap before it), in the proposed method for the manufacture of simulated black granular caviar from natural products, including the preparation of the initial aqueous solution from a filler and a gel-forming substance, heating the solution and filtering it, the subsequent formation of spherical grains is carried out by batch feeding the initial solution with one or several free (without forced pressure and spraying) jets with a diameter of 3-5 mm into a container with a forming liquid heated in the upper part - vegetable oil, which is preliminarily informed of a uniform rotational movement at a speed depending on the required grain size, and the subsequent ones immediately after the supply of a portion of the solution: transportation, cooling and separation of grains from the forming liquid (oil) is carried out simultaneously - by draining the mixture by gravity into a vessel with rotated water (tap water), which, in order to prevent the grains from sticking together and to better wash them off the oil, is also given a rotational movement, after which the emerging formation fluid is removed through a forming fluid - water, a drain valve, and the grains are directed by gravity to a separation sieve . Further operations: coloring of grains, washing, salting and flavoring is carried out similarly to the prototype.

 The large diameter of the jet of the initial solution and its nature also make it possible to supply the initial solution to the forming liquid simultaneously with its filtration.

 For the same purpose, the proposed device for forming spherical grains from food products, containing a container for the initial solution with exhaust pipes, a container for a forming liquid - vegetable oil, equipped with a heating element in the upper part, a container for cooling and separating the grains from the forming liquid, a separation sieve with a drain tank and pipelines for supplying chilled water and draining the forming liquid, the device is made in the form of a hollow, leaky, divided into 2 (upper and lower) h the part of the vessel, the upper part of which serves as a container for the forming liquid and is installed directly on the lower part filled to a certain level (depending on the volume of oil and grains) with water cooled as a cooler - separator of grains from the forming liquid, and the pipe for the chilled water supply is connected to the lower part of the tank for separating grains from the forming liquid, and the pipeline for separating grains from the forming liquid, and the pipeline for draining the forming liquid is strengthened in the middle part of the latter at the boundary of the forming liquid - water, both containers equipped with electric actuators, made in the form of blades, mounted with the possibility of rotation in the middle part filled with the corresponding capacity of the working medium, and drain valves for unloading grains. In this case, the capacity for the initial solution is made in the form of an open funnel with one or more discharge tubes with an internal diameter of 3-5 mm, communicating the cavity of the funnel with a forming capacity through openings in its lid, located around a circle with a certain distance from the center depending on the speed of rotation activator and the required grain size. The expendable funnel is made in the form of several sections isolated from each other by partitions, one of which is used to refuel the forming tank with oil and therefore has a larger diameter of the exhaust pipe than the others. In addition, in order to ensure the combination of the process of supplying the initial solution to the forming tank and filtering it, the funnel can be equipped with an insert filter mesh.

 The drawing shows the design of the proposed device, section.

 The device consists of a cylindrical hollow vessel, divided into 2 parts: the upper container 1 with forming liquid 2, which is closed by a lid 3 and equipped with a heating element 4 in the narrowed part, and the lower one is a grain cooler-separator 5 from oil. Both tanks are equipped with activators, made in the form of blades 6, mounted on the roller 7 of the electric motor 8 and located in the center of the working medium of each tank. In the lower part of both tanks there are taps 9 and 9 'for unloading grains, and on the side surface of the cooler-separator 5 there is a pipeline with a valve 10 for draining the forming liquid from the tank, located on the dividing line forming liquid - water (after oil inlet with grains) . For pouring chilled water to a certain level (i.e., below the pipeline with a tap 10 by an amount h proportional to the volume of grains), a pipeline with a funnel 11 is provided. In the openings of the lid 3, the tubes for the initial solution 13 are fixed in tubes 12, made in the form of an open funnels, divided by partitions 14 into several isolated sections, one of which is used to refuel the forming liquid, for which the outlet channel 15 has a slightly larger diameter than the others. A filter mesh 16 can be inserted into the funnel. The device is also equipped with a separating screen 17 with a drain tank 18.

 The manufacturing results of 1 kg of simulated granular caviar using the proposed device for the formation of spherical grains are presented in the table. With the indicated size ratios, selected experimentally: the diameter of the jet of the infused stock solution d = 3-5 mm and the linear velocity of rotation of the forming liquid V = 0.2-0.27 m / s, the grain size most closely simulates the grain of natural fish roe, and the percentage defective (deviation from the optimal grain size) is minimal. It does not matter if the initial solution is injected into the forming liquid or into the air gap before it.

 The proposed method for the formation of spherical grains allows you to use (make) the simplest devices for its implementation of almost any size (depending on the required volume of a single portion of the finished grains) - from minimal (portable) to high-performance, stationary.

 Moreover, as shown by the operation of the prototype at home, the specific productivity of the device at the same level of quality significantly exceeds existing analogues, since 1 kg of the initial solution in 1 min passes through each feed channel of the supply funnel (in the prototype - 0.05-0 06 g / min).

 Feasibility study of the use of the claimed invention consists in a significant simplification of the design of the device, therefore, reducing the complexity of its manufacture and maintenance, simplifying and reducing the complexity of the manufacturing process of simulated granular caviar, as well as a multiple increase in the productivity of the device.
