Description

The present invention relates to a technology for producing instant tabletted products and can be used in food, pharmaceutical, chemical and related industries to obtain instant products in the form of tablets, briquettes.

Known instant products for preparing hot or cold drinks such as coffee, tea, soft drinks, and the like. are made in the form of powders or granules. The disadvantages of producing these products in the form of powder and granules are the complexity of dosing the amount of the product to the volume of liquid, the ability to easily disintegrate, and in some cases the duration of the dissolution process. To eliminate these disadvantages, products in the form of a powder or granules are compressed into a finished product in the form of a tablet or briquette. Compression of the product, however, tends to increase the disintegration time of the tablet when mixed with a liquid. To accelerate the disintegration of the tablet in liquid, at least one disintegrating substance is added to its composition. Often, the cleaving agent has undesirable chemical, physiological and organoleptic properties, which makes the product less attractive to the consumer and not competitive in the market.

Closest to the claimed technical solution is the invention RU 2370048, publ. 20.10.2009. The invention relates to molded instant pieces that are made from an instant composition obtained by a method having the steps:

a) preparing an instant composition, wherein the instant composition is powdery, granular or grainy;

b) molding the instant composition, the instant composition, when molded, has a water content of 0.01 to 40% by weight (based on total weight);

c) drying the formed instant composition under vacuum. Moreover, the instant composition contains isomaltulose.

The essence of the invention lies in the fact that vacuum drying an instant composition with a water content of 0.01 wt% or more and 40 wt% or less (based on the total weight) leads to the formation of dry, storageable, shaped instant pieces, which have a porous structure or matrix. This porous structure or matrix can be very well penetrated by a liquid in which the instant product dissolves, whereby the liquid acts like a disintegrating agent in the shaped instant piece. The porosity of the molded instant piece significantly improves the dissolution characteristics, primarily due to the capillary action of the structure. The disintegration time of the shaped instant pieces is greatly reduced compared to tableted, compressed or powdered instant products.

The disadvantages of this invention are that the product composition must be pre-moistened, which implies a preliminary stage of water preparation and the availability of equipment for its preparation and direct moistening of the product composition. In addition, the freeze-drying stage also requires equipment and leads to unnecessary energy consumption. All this complicates the technology and leads to low energy efficiency of the entire process.

The task of the proposed technical solution is to obtain a tableted instant product with a low disintegration time and dissolution when mixed with a liquid without the use of additional disintegrating substances.

This problem is solved due to the fact that the claimed method of obtaining tableted instant products allows you to obtain a developed porous structure, which, when in contact with a liquid, makes it possible to intensify the interaction of the liquid and the product, which will lead to accelerated disintegration and dissolution.

The method includes the following stages: a) preparation of the instantiated composition of the product; b) mixing the instantiated composition with CO ₂ , which is in a solid state of aggregation; c) forming a tablet or briquette of the desired shape and size; d) sublimation of solid CO ₂ and the release of CO ₂ in a gaseous state from the inner layers of the tablet with the formation of a developed porous structure.

The technical result, provided by the above set of features, is to reduce the duration of disintegration and dissolution of the tableted instantiated product upon contact with a liquid.

The method is carried out as follows.

The product in the form of powder or granules is dosed and mixed with CO ₂ , which is in a solid state of aggregation, in the required proportion, depending on the type of instant product. If necessary, a highly volatile binder such as ethyl alcohol can be added to increase the binding capacity of the product particles.

Then there is rapid mixing with a stirrer in order to obtain a homogeneous mixture of powder / granules of the product and CO ₂ , which is in a solid state of aggregation. The mixing speed is selected based on the goal - to minimize the duration of the mixing process so that CO ₂ does not sublimate.

After receiving the mixture, it is dosed into the matrix and pressed. The magnitude of the pressing pressure is selected individually for each product. In the process of pressing, the matrix and the piston are cooled, if possible, to reduce the heat flux to the mixture in order to reduce the loss of CO ₂ from sublimation.

The molded tablet is placed in open air at a temperature of 20-25 ° C. There is a process of sublimation of solid CO ₂ from the inner layers. In the process of sublimation, CO ₂ in a gaseous state leaves the inner layers of the product, forming a porous structure.

The sublimation process can be carried out in a closed chamber and the resulting CO ₂ gas can be captured for further processing.

The resulting tableted instant products due to the developed porous surface have a disintegration rate several times higher than that of tableted products obtained without the use of CO ₂ or with the use of auxiliary disintegrating substances.

Example 1

Components:

Dry mix for obtaining the instant drink "Kissel" in the form of a powder.

CO ₂ in a solid state of aggregation.

The binder is ethyl alcohol with a concentration of 50 vol.%.

Process:

In a pre-cooled dish (down to -20 ° C) was placed 5 g of the instant drink "Kisel" powder, 5 g of CO ₂ in a solid state of aggregation was added and thoroughly mixed until a homogeneous mixture was obtained. Next, a binder component, 0.5 g of ethyl alcohol, was introduced and the mixture was mixed again.

After that, the mixture was fed into the die and pressed with a piston. The pressing force was 100 kgf / cm ² . The resulting tablet was removed from the matrix and left in the open air at a temperature of 20 ° C. Sublimation of CO ₂ from the inner layers of the tablet took place for 20 min.

The duration of disintegration of the tablet in water obtained by this method to obtain a drink was 10-15 seconds. In comparison, a tablet prepared under the same conditions but without addition of CO ₂ followed by sublimation had a disintegration time in water of 2-2.5 minutes.

Example 2

Components:

Instant Beef Broth Blend.

CO ₂ in a solid state of aggregation.

Process:

In a pre-cooled dish (to -20 ° C), 5 g of the mixture was placed to obtain an instantiated beef broth, 5 g of CO ₂ in a solid state of aggregation was added and thoroughly mixed until a homogeneous mixture was obtained.

After that, the mixture was fed into the die and pressed with a piston. The pressing force was 100 kgf / cm ² . The resulting tablet was removed from the matrix and left in the open air at a temperature of 20 ° C. Sublimation of CO ₂ from the inner layers of the tablet took place for 30 min.

The duration of disintegration of the tablet in water with a temperature of 70 ° C, obtained by this method, was 2-2.5 minutes. In comparison, a tablet prepared under the same conditions but without addition of CO ₂ followed by sublimation had a disintegration time in water of 25-30 minutes.

Thus, it can be seen from the examples that the implementation of the present invention makes it possible to obtain a developed porous structure of tableted instant products, which, upon contact with a liquid, makes it possible to intensify the interaction of the liquid and the product, which leads to accelerated disintegration and dissolution.
