Abstract

The invention relates to the food industry, to the canning and wine-making industry, namely, to devices for loosening grape marc. The purpose of the invention is to increase reliability in operation. In the device for loosening grapes on each of the rolls 3 installed in the outlet of the hopper, the rods 8 are fixed. The rods 8 fixed on one of the rollers are located along the length of the roll in the middle between the rods 8 of the second roll 3. The ratio of pitch between the rods 8 m along the length of the rolls 3 and the pitch of the helix of the scourge 6 on the shaft 5 is 2: 1. Grape squeezes are crushed by rods 8 into pieces with a size corresponding to the spacing between the rods 8. The crushed mass enters the cavity of the perforated cylinder and is caught by the whips 6 of the shaft 5. The capture of pieces of material by the whips 6 occurs ;; thanks to the ratio (8c / 5cG) (2/1). The husks are loosened intensively by interacting with the whips 6 and rotating; they are cylinder 4. The holes of the perforations of the cylinder are filled in such a way that they allow the seeds of the grapes to pass.

The invention relates to the food industry, to its canning and wine-making industry, namely to devices for loosening grape marc,

The purpose of the invention is to increase reliability in operation.

FIG. 1 schematically shows a device for grape pomace opening, a longitudinal section; in fig. 2 shows section A-A in FIG. one,

A device for loosening grape husks includes a housing I, a hopper 2, in the outlet of which a pair of rolls 3 is installed, a perforated cylinder 4 in housing 1, mounted inside shaft 5 with scourges 6 fixed on shaft 5 to form a helix. At the bottom of the device, under the perforated cylinder 4, a discharge screw 7 is placed. On each of the rolls 3 radially, in pairs symmetrically and with an equal step along the length of the roll 3, the rods 8 are fixed. The rods 8, fixed on one of the rolls, are located along the length of the roll in the middle between rods B of the second roll. The ratio of the pitch between the rods 8 along the rolls 3 to the helix pitch of the location of the scourges 6 on the shaft 5 is 2: 1. The holes of the perforation of the cylinder 4 are made so that they allow the passage of grape seeds. There is a discharge chute 9 in the device case in the area of the end part of the perforated cylinder 4. There is a discharge side 10 in the bottom of the device housing in the area of the discharge part of the screw 7. Rolls 3 , perforated cylinder 4, shaft 5 and screw 7 are driven (not shown).

The device works as follows.

The pressed grape marc is fed into the hopper 2 and is directed to the rolls 3 rotating in the opposite direction. In this case, the rolls 3 with the rods 8 crushed the material into pieces with a size corresponding to half the step between the rods 8 along the length of the rolls (Sc./2). The crushed mass enters the cavity of the perforated cylinder 4 and is captured by the whips 6. shaft 5. The shaft 5 with whips 6, rotating at a high angular velocity, loosens the material in

account of the presence of centrifugal forces. The capture of pieces of material by the whips 6 is due to the correspondence of the ratio (Sc./S, S) (2/1). This ratio is justified by the fact that if (Sc / S /) (2/1), then pieces of material pass between adjacent scourges 6, located on the generator shaft 5, and are not subjected to centrifugal force and, consequently, intensive loosening. If (S | j / S (/ -) (2 /), then the efficiency of loosening and separation of seeds decreases as it is difficult to loosen large pieces of material with whips 6 in the zone of perforated cylinder 4, For normal operation of the shafts 3 with st rzhn E 8 and the shaft 5 with 6 mi bkcha- limiting parameter is the pitch of the helical line arrangement on pests ScT shaft.

As a result of intensive disintegration of the husk by the whips 6 and the rotating cylinder 4, the seeds are separated from the husks and through the openings of the cylinder 4 enter the cavity of the discharge screw 7, which moves them, and through the discharge port 10 are unloaded from the device. The remaining part of the Marc due to the screw-like arrangement of the scourge 6 on the shaft 5 moves along the axis of the cylinder 4 and through the tray 9 is sent to the next processing operation. one

By making rolls with

the rods and the release of the ratio of the pitch between the rods along the rolls 3, the helix pitch of the scourge on the shaft 5 equal to 2: 1, as well as the choice of the size of the perforated cylinder with the condition of the grape seed passage in them increases the reliability of the device and more complete separation of seeds from marc that are later widely used in the food, feed and other industries of the national household.
