For wiping fruits and berries without a stone, as well as a sulphated cherry with a bone having a small spherical shape, wiping machines are used for rubbing fruit and berry puree.
Received after wiping sulfited fruits and berries bargaining in preparation for the production process as well as the usual applesauce or fruit-berry puree.
Dry applesauce; Dry apple puree (apple powder) is pre-soaked in cold water for 2-3 hours to facilitate its dissolution.
Then, the rest of the water is added to the mixture so that the liquid purée also has 12-15% of dry matter, and the mass is thoroughly mixed.
The resulting liquid apple puree is subjected to a double rub through sizas with a diameter of cells of 1,5-2 mm and with a cell diameter of not more than 1 mm on the wiping machines. The wiped reconstituted puree is immediately sent to the production for use because of its weak microbiological resistance.
Fruit podvarki and supplies. Dense fruit and berry preparations - cooks, supplies, - preheated or diluted with sugar syrup, then wipe through a sieve with a cell size of not more than 3 mm.
Fresh fruits, fruits in syrup, candied. Fresh grapes, used for finishing cakes and pastries, are cut off from the brush before being put into production, washed on a sieve with water, separating spoiled and damaged berries.
Fresh tangerines release from the membrane and divide into wedges.
Fruits in syrup recline on a sieve and cut into slices with a knife to the desired size, or for crushing is passed through a machine-type grinder.
Candied fruit is carefully scanned, removed in case of detection of twigs, stems and accidentally caught foreign objects, cut into slices of the required size or crushed on the machine if candied fruits are used in chopped form.
Dried fruits (raisins, prunes, etc..). Raisins, prunes and other dried fruits should be moved with the removal of twigs, pedicels and foreign impurities and washed in clean water on sieves or in a car.
Cleaning and washing of raisins can be made on a special raisin cleaning machine consisting of a trough-shaped metal casing, a stationary grating drum and a paddle shaft with screw blades and hair brushes. To trap metallic impurities in the charging part of the machine, permanent magnets are installed.
