RU214894U1 - Device for obtaining granules of simulated caviar - Google Patents

Abstract

The utility model relates to the food industry and can be used in the production of a product that imitates granular caviar. The technical result obtained in the claimed solution is to obtain granules with a size in the range from 0.35 mm to 3.0 mm, having a round surface, on the installation with minimal labor and high productivity. The achievement of the technical result is facilitated by the fact that the installation has an encapsulation unit, which includes a disperser, rotating which creates a centrifugal force that ejects the raw material through the holes in the disperser only due to this force. The raw material is fed into the disperser in a weak stream. In this case, the formation of the droplet size depends on the size of the holes. The raw material, having passed the holes, is ejected through the air to the CaCl fixer. Having formed in the air in the form of a ball, drops, falling, fall into the fixer.

Description

The utility model relates to the food industry and can be used in the production of a product that imitates granular caviar.

Known installation and method for the production of algin caviar [Storozhilov Victor Fedorovich, Storozhilov Sergey Fedorovich, Semionenko Petr Nikolaevich, "Installation for the production of algin caviar", RF Patent No. water, feed mixing nozzle, first suction pipe, first pressure pipe, stabilizer tank, second pressure pipe, second pump, second suction pipe, pressure tank, settling tank, equalizing siphon, additional pipe for continuous pellet output, pellet output pipe, sump, dispensing nozzles, second treated water supply line, pellet sieve, pickling tank, third treated water supply line, second sump, finished product outlet line and finished product collection tank and two-part pressure line.

The only operation where manual labor is used is the movement of the pellets into the salting tank. In the tank of the original product, into which a preservative (sodium benzoate) is added and polysaccharides are introduced, in particular alginic acid salts, sodium alginate, calcium alginate, agar, and so on, water enters through the first prepared water supply pipeline. Using a mixing nozzle, the initial product is prepared, which is fed to the pressure tank with the help of the first pump through the first pressure pipeline, from where it enters the granulator settling tank through the dispensing nozzles. From the granulator, the granules enter a pallet equipped with a sieve. During such transportation, the granules are not subjected to deformation and damage, so the final product is of high quality. In this case, the second pump removes excess calcium chloride solution from the first and second trays. Excess calcium chloride solution is returned to the granulator settling tank, increasing the amount of solution to the required level.

Due to the installation of an additional pipeline in the upper part of the settling tank, the outlet of which is located above the pallet, it is possible to improve the quality due to a more intensive withdrawal of granules from the settling tank and at the same time reduce the energy consumption of the granulator during operation.

Improving the quality of the final product and the productivity of the installation is also facilitated by the fact that the second pipeline for supplying prepared water is connected to the settling one.

In nozzles with cone-shaped inner holes installed directly on the bottom of the pressure tank, the outlet holes are not clogged, since the polysaccharide solution easily slides along the inclined inner walls of the nozzle and does not stick to them. Drops of the polysaccharide solution are evenly separated and enter the settling tank, which ensures a high quality end product.

The disadvantages of the device include high complexity, high labor costs for obtaining the product and the impossibility of obtaining granules with a size of less than 0.7-0.8 mm.

A known method of obtaining food granular caviar [Kim I.N., Kim G.N., Maksimova S.N. "Method of obtaining food granular caviar", RF Patent No. 2264133 dated 06/03/2004].

The method of obtaining caviar is carried out by extrusion granulation in a standard device, which is two pipes located one inside the other. The filler is fed through the inner pipe, and the solution of the gelling agent - simultaneously through the outer pipe of the device for molding granules. At the outlet of the device, the filler droplets are enveloped in a gelling agent solution, which forms a surface film (shell) and enters the liquid medium. The resulting granules are separated, washed with 10.0-15.0% aqueous sodium chloride solution for 10-15 minutes. The washed granules are subjected to cooking with a protein water-oil emulsion (taste emulsion) containing table salt, flavoring, aromatic and coloring substances, and sent for pasteurization.

The disadvantages of the device include the instability of the size of the granules and the impossibility of obtaining granules smaller than 1 mm.

A known method for producing artificial granular caviar [Vilesov A.D., Vilesova M.S., Zhuravsky E.P., Aizenshtadt N.I. "Food artificial granular caviar and method for its production", RF Patent No. 2148372 of 05/10/2000].

SUBSTANCE: method for producing food artificial granular caviar includes preparing an initial mixture for forming granules, supplying an initial mixture for forming drops, forming granules in oil, separating granules from oil, cooking granules with an emulsion, packing and packaging, and is characterized in that preparing an initial mixture for forming granules carried out in the following order: first, a matrix of granules is prepared, for which gelatin and sodium alginate solutions are mixed, heated to a temperature of 30-60 ° C, then baking soda, powdered milk are introduced into the above solutions, at the same temperature, sequentially and with continuous stirring, egg powder, finely dispersed activated carbon and droplets are formed from the finished initial mixture through a system of dies, and the formation of granules is carried out in vegetable oil in uniform rotational motion, the upper layer of which is cooled to a temperature of 5-10 ° C, the resulting granules are separated from the oil by filtration and produced t culinary processing of granules by dry salting with sodium chloride with the addition of sodium glutamate and then mixed with a protein-oil emulsion, for which a protein-oil emulsion is prepared by mixing solutions of gelatin and sodium alginate, into which finely dispersed activated carbon, sodium chloride, vegetable oil are sequentially introduced , monosodium glutamate, fish paste or fish brine, and then the resulting finished caviar is packaged and packaged.

In addition, the formation of drops from the initial mixture is carried out by the method of vibration exposure.

The method of forming drops from the initial mixture is based on the dynamic method of splitting a laminar jet of liquid mass flowing out of spinnerets of a certain diameter at a certain speed under compressed air pressure.

The disadvantages of the device include high complexity, high labor costs for obtaining the product and the impossibility of obtaining granules with a size of less than 1-1.2 mm.

The closest analogue of the claimed technical solution is the method [Vakhrushev A.I., Maksimova S.N., Voropaeva Yu.A., Poleshchuk D.V., Strizhova M.A. "Method of obtaining an analogue of food granular caviar", Patent of the Russian Federation No. 2422050 dated 06/27/2011].

The method includes preparing an initial mixture for forming granules containing a protein component, sodium alginate, flavoring and coloring substances in a certain ratio. Then produce the formation of granules in a solution of calcium chloride and keeping the granules in a solution of chitosan. The resulting granules are separated from the receiving medium, washed and packaged. EFFECT: invention provides obtaining an analogue of edible granular caviar with a structure and consistency characteristic of natural granular caviar.

In the method for obtaining an analogue of food granular caviar, including preparing the initial mixture for the formation of granules, the formation of granules in the receiving medium, separating the obtained granules from the receiving medium, washing them and packaging the finished caviar, a mixture of the protein component with sodium alginate is taken as the initial mixture, the formation of granules carried out in a solution of calcium chloride, the obtained granules are kept in a solution of chitosan, while the initial mixture contains components in the following ratio, wt.%.

Also, the formation of granules is carried out in a solution of calcium chloride with the addition of chitosan.

In this case, the initial mixture may contain vegetable oil or fish oil.

The finished product is a granular mass consisting of monolithic, jelly-like granules.

The formation of the shell of the granules is carried out when drops of the initial mixture enter the receiving medium containing a solution of calcium chloride. In the process of interaction with the medium, the surface of the drop is covered by the shell, the drop seizes, retaining a spherical shape. Over time, the thickness and strength of the shell increase, the structure of the granules becomes stronger, they do not deform. The granules retain their integrity during their mixing and almost completely imitate the grain of natural fish caviar.

The disadvantages of the device include the instability of obtaining round granules with a size of less than 0.7-0.8 mm.

The proposed utility model solves the problem of obtaining granules of simulated caviar with a size in the range from 0.35 mm to 3.0 mm, having a high quality spherical surface, with minimal use of labor costs and high productivity of 150-160 kg of raw materials per hour.

The set technical problem is achieved by the fact that the device includes a hopper, in the upper part of which a coagulant supply pipeline is mounted, made with the possibility of its continuous flow down the walls of the hopper, and in the upper part of the alginate supply pipeline. In the lower part of the hopper there is a branch pipe for removing granules, in the center of the upper part of the hopper there is a bushing made with the possibility of rotation by means of a servo drive through the bearing assembly, with holes for spraying the alginate entering it through the rotary joint into the coagulant, while the holes are formed by the intersection of spiral slots, made on the outer side of the sleeve and slots on its inner side. The slots on the inside of the sleeve can be vertical or helical. The device may include a servo control unit configured to change the rotation speed of the hub. By changing the size of the holes on the surface of the sleeve and the rotation speed, you can get different sizes of eggs.

The proposed version of the device for obtaining granules of simulated caviar is illustrated by the drawings shown in Fig. 1-4.

Fig. 1 is a general view of a device for obtaining granules of simulated caviar.

Fig. 2 is a plan view of a device for producing simulated caviar pellets.

Fig. 3 - a node with a rotating sleeve with holes located on it for spraying alginate into the coagulant.

Fig. 4 - view with holes on the sleeve.

The claimed device in Fig. 1 includes a hopper 1 with inclined walls and a conical bottom without a cover, on the side of which a coagulant supply pipeline 2 is mounted, made with the possibility of its continuous flow down the walls of the hopper 1 and in the upper part the alginate supply pipeline 3 (raw material), and in the lower part placed branch pipe 4 for the removal of granules. In the center of the upper part of the hopper 1 is mounted, made with the possibility of rotation by means of a servo drive 5, controlled by the block 6, through the bearing assembly 7 (Fig. 3) bushing 8, with holes 9 for spraying the raw material entering it through the rotary union 10 into a coagulant, with In this case, holes 9 are formed by the intersection of vertical slots on the inner side of the sleeve 8 and spiral slots on the outer side (an option with internal and external spiral cutting of slots is possible).

Rotation to the bushing 8 is transmitted through the belt pulley 11, which is pressed along the hollow shaft 12 through the washer 13 by the nuts 14 to the tapered roller bearing 15. The tapered roller bearing 15 is installed along the outer diameter in the bearing housing 16, in which the single-row ball bearing 17 is also installed. Sleeve 8 is fixed on hollow shaft 12 through seals 18 and 19, covers 20 and 21 by preloading washer 22 and nuts 23.

The operation of the claimed device for obtaining granules of simulated caviar, shown in Fig. 1 proceeds as follows.

Alginate (raw material) and coagulant are fed through their separate pipelines 2 and 3 to the device. Further, through the rotary joint 10, the raw material enters the rotating sleeve 8 with holes 9 located on it for spraying the alginate into the coagulant.

The control unit 6 sets the rotation speed of the electric servo drive 5, which rotates the sleeve 8 (Fig. 3).

On the inner side of the sleeve 8 there are vertical slots from top to bottom, and on the outer side there are spiral slots (an option with internal and external spiral cutting of slots is possible). When these slots intersect towards each other, holes 9 are obtained (Fig. 4). Drops of alginate, passing through the holes 9, already have the potential energy of rotation, due to the rotation of the sleeve 8. This rotation occurs in a horizontal plane. Due to the internal cut thread, this rotation also receives rotation at an angle. Thus, after separation of the alginate drop from the surface of the sleeve 8, the drop receives a tangential rotation. Under the action of centrifugal forces inside the drop, a sphere of the correct shape and the required size flies to the coagulant (fixer), thereby forming a caviar.

The fixative flows with the flow necessary to prevent the formed eggs from sticking to the walls of the hopper 1. Next, the eggs are separated from the fixative and washed with water.

The advantages of the proposed device are that it is supposed to use low-power pumps, since weak feed flows of raw materials and a fixer are required, as well as obtaining high-quality granules of simulated caviar with a smooth surface and regular spherical shape, with minimal labor costs.
