The invention relates to the confectionery industry, in particular to a method for producing a sugar semi-finished product, and can be used in the confectionery industry in the production of cold candy.

The purpose of the invention is to improve the quality of the semi-finished product,

The method is carried out as follows.

 A sugar-making syrup is prepared at 80-90 ° C with a molasses content of 15-20% and a dry cavern of 70-75%. In parallel, powdered sugar is prepared with a dispersion of crystal particles of 30-50 microns. Pre-mix the sugar-syrup syrup and powdered sugar until a homogeneous suspension is obtained in a ratio of mass parts

sugar-syrup syrup and powdered sugar, respectively, 1: 1 - 10: 3. The resulting homogeneous suspension is sprayed by a pneumatic nozzle at a pressure of compressed air of 0.3-0.4 MPa into the drying chamber of the apparatus, where the modified starch is additionally sprayed to the sprayed suspension in an amount of 5-7% by weight of the finished semi-finished product. The sprayed suspension particles with a dispersion of 30–50 µm, colliding with the particles of the modeled starch with a size of up to 100 µm, form aggregates of 0.9–1.2 mm. The resulting aggregates in the drying chamber are dried to a final moisture content of 0.5-1.0% at a temperature of hot air stream of 170-180 ° C. The finished prefabricated is separated in cyclone from the field.

When reducing salt |; :; ani of sugar pudo in a sugar-free gyro less than 14 (poi; 1: n 1}.; one hundred dis,:. more, and small aggregates of small sizes are formed. When the atom is in excess, the e is yestro ( sugar refill (.yy s: p) for drusen from caxapo3i.i crystals, as a result of which, hyoopa b-inclusion drops of sugar powder crystals can form and that ultimately leads to a reduction in the size of the semi-finished aggregates (20-200 µm). the content of powdered sugar in a syrup over 3:10 (example 5) is undesirable because it reduces the content of the binding substance and (syrup), noebiuja- a polydispersity of sizes and aggregates are reduced if saharopatochny syrup acts as a binder for powdered sugar crystals drusen, the modified starch -. for dry-aggregates of drusen powdered sugar.

Dispersed drops of sugar refractory syrup with inclusions of powdered sugar crystals are aggregated and dried in a mixed air flow with a temperature of 170-180 ° C. Only sbicyujeH aggregates reach the periphery of the drying chamber. They are in contact with the sprayed particles of modified starch at the periphery of the drying chamber. In this case, dry aggregates are enlarged only if they have an adhesive ability with starch particles.

At 170-180 ° C of a hot air stream, dry aggregates are not only dried, but also partially plasticized by the thermoplasticity of an amorphous substance from a sugar-sugar syrup on the surface of powdered sugar crystals. Consequently, partially plasticized dry aggregates, colliding with particles of modified starch, aggregate into larger sizes. At the same time, iodified starch dramatically increases the thermoplasticity (strength) of the aggregates. Thus, a decrease in the content of modified starch in the semi-finished product leads to a decrease in the size of the aggregates, and an increase in the amount of modified starch in it also leads to

reduce the size of the aggregates and increase polydispersity.

If the content of modified starch is less than 5%, it reduces the size of the aggregates of the semi-half (3 briquette due to insufficient binding component, an excess of more than 7% causes a sharp increase in the thermoplasticity of the aggregates and a decrease in their adhesive ability.

Hot air temperature

reduces the thermoplasticity of the amorphous substance of the aggregates, and an excessive temperature rise (over 180 ° C) can lead to the destruction of the aggregates as a result of a decrease in their strength (the size of the aggregates decreases). At a temperature of less than 170 ° C of a hot air flow, the thermoplasticity of the aggregates is insignificant;

and dimensions (less than 300 microns).
