Description

The invention relates to the field of processing industry, in particular to small-sized equipment, and can be used in enterprises for the processing of berries.

Currently, there are small-sized destemmers on the grape processing equipment market, each machine differs in the design features of the working chamber and the type of working body. Such a variety causes difficulties with the correct selection of equipment for destemming grapes, existing designs have the following disadvantages: complexity of operation and maintenance, low efficiency of destemming, manual unloading of ridges, high power costs and high content of tannins in the must.

Known device "Malka with a destemmer for grapes" patent for utility model No. 158469 publ. 01/10/2016, containing a body with a loading hopper, a crusher for berries, which is two rollers with horizontal ribs, a shaft on which the blades are installed, a mesh sieve made in the form of a half-cylinder, a tray for collecting pulp and juice.

The disadvantage of this device is that the movement of berries inside the destemmer is difficult and leads to clogging, since the unloading of the ridges is not provided, it is required to stop the equipment and clean the ridges manually. The square shape of the tray impairs washing and cleaning after the technological process, product residues will get stuck in the corners of the casing.

The closest in technical essence is the "Device for grinding food media" RF patent No. 2054272 publ. February 20, 1996, containing a body with a loading hopper, a tray for removing the wiped mass and for removing the unwiped mass.

The disadvantages of this device are the narrow technological capabilities due to the complete wiping of the loaded raw material without separation into fractions, which excludes the possibility of cleaning the raw material or separating seeds, seed chambers or films from slices.

The objective of the proposed technical solution is to develop a device for kneading grapes and separating the ridges from them.

The problem is solved by the fact that a device for kneading bunches of grapes and separating ridges from them, containing a body with a loading hopper, a crusher for berries, which is two rollers with horizontal ribs, a shaft on which the blades are installed, a mesh sieve made in the form of a half-cylinder, a tray for collecting pulp and juice, characterized in that it is equipped with a pumping auger for brushes with berries and an unloading auger for combs, a tray for unloading combs, a tray for pulp, which is installed at an angle of natural slope for draining juice and pulp.

In FIG. 1 shows a general view of a device for kneading grapes and separating ridges from them. In FIG. 2 - side view in section, where 1 - hopper, 2 - box, 3 - fixed roller, 4 - movable roller, 5 - shaft, 6 - electric motor, 7 - axle, 8 - return spring, 9 - gear wheel, 10 - shaft, 11 - blades, 12 - mesh sieve, 13 - gear wheel, 14 - pulp tray, 15 - ridge collection tray, 16 - blowing auger, 17 - unloading auger.

The device for kneading bunches of grapes and separating the ridges from them contains an upwardly expanding hopper 1 mounted on support bars on the box 2. Under the exit from the hopper 1 there is a device for kneading berries, which is two rollers with horizontal ribs 3 and 4. Horizontally stationary roller 3 rigidly connected to the axis of the shaft 5 and an electric motor 6 is fixed at its end. The horizontally movable roller 4 is fixed on the axis 7 pressed by a clamping device mounted on one of the support bars, with a return spring 8, which, using a screw with a nut, regulates the gap between the gear wheels 3 and 4. A gear wheel 9 is installed on the shaft 5. 10 - a shaft, devices for separating the ridges, on which the blades 11 are installed in a spiral, the injection coil 16, the unloading 17. The shaft 10 is placed in a mesh sieve 12 made in the form of a and curved outward upper edges, fixed in the box 2. On the shaft 10, a gear wheel 1 is installed 3. The diameter of the gear wheel 9 is significantly larger than the diameter of the gear wheel 13. The gear wheels 9 and 13 are interconnected, for example, by a chain drive. Below the body 2, a pulp tray 14 is installed, and a tray for collecting ridges 15 is installed on the side of the destemmer.

The device works as follows. Bunker 1 is loaded with bunches of grapes. The electric motor 6 rotates the shaft 5, causing the roller 3 to rotate. roller 4 is engaged with it, it also starts to rotate. During rotation, rollers 3 and 4 grab the grapes, knead them and feed them into the mesh sieve 12 of the device for separating the ridges. Because shaft 5 is connected to shaft 10 through gears 9 and 13 by a chain drive, shaft 10 starts to rotate, and due to the difference in the diameters of gear rings 9 and 13, shaft 10 rotates at a significantly higher speed than shaft 5. Rotating, shaft 10 is driven by a screw 16 grabs the combs with berries and pushes them to the blades 11, the blades 11 tear off the berries from the combs and crush them, the mass of the combs with berries moves forward due to the blades. Crushed berries, falling into the sieve, fall through it and fall into tray 14, set at an angle for draining juice and pulp, and peeled ridges are pushed further with the help of an unloading auger 17 and removed into the tray for ridges 15.

The claimed device for kneading bunches of grapes and separating the ridges from them is easy to manufacture and operate, multifunctional. It can be widely used in the processing of berries in enterprises of small productivity.
