Description

The invention relates to equipment for the field of public catering and can be used both in catering establishments and for individual use at home.

A device for wiping food products is known, comprising a loading hopper and a rotating, horizontally arranged cylindrical drum with a perforated wall in which a screw is mounted, as well as a second drum of a similar design, mounted parallel to the first with a clearance relative to it and with counter rotation, and the hopper is reinforced with such so that the outlet is located above the gap.

A disadvantage of the known device is that it only wipes cooked vegetables; during operation, a large percentage of vegetables get into the waste. Thus, raw vegetables and fruits cannot grind this device.

A device for chopping vegetables and fruits is also known, comprising a housing with a lid, a drive rotor installed in the housing and knife blocks, the rotor is made in the form of a drum and is provided with a fixed, rigidly mounted inside its curved plate for pressing the product. In this case, the knife blocks are placed on the side wall of the drum with cutting edges inside it, and in order to reduce product losses by minimizing the gap between the plate and the cutting edges, the fixed curved plate is equipped with a cam mounted on one end to rotate and fix it.

The disadvantages of the known device are that it works poorly, unreliably, with losses of the crushed product. The plate inside the drum presses the product in a limited amount, it takes a lot of time to fix the product with the plate, the extraction of residues is crushed (L

product, which ultimately reduces productivity.

The aim of the invention is to increase the efficiency and productivity of the device, expanding its technological capabilities.

The goal is achieved in that the device for chopping vegetables and fruits comprises a drum with a drive shaft, knife blocks placed inside it, the drum consists of two vertically mounted disks with knife blocks mounted on their inner surfaces, and a horizontal perforated space placed between the disks seagulls, while one of the disks is mounted on the drive shaft and rigidly fastened to the shell, and the other is kinematically connected to the latter to rotate in the opposite direction, moreover, Attached to the shell, it is spring-loaded and mounted with the possibility of its longitudinal movement along the axis of the drum for complete grinding of the product.

The use of a horizontal drum, a system of gears-satellites, a gear made on the drum cover, removable disks with knife blocks, disk holders, springs in the claimed device will increase the efficiency of the device, its productivity, since the design of the claimed technical solution allows abrade vegetables, both raw and boiled, fruits inserted into the drum in any quantity in one cycle without loss of the crushed product, and removable disks with a different set of knife blocks - to produce grinding products of various types, sizes, particles of the crushed product.

The technical and economic efficiency of the claimed technical solution in comparison with the prototype is as follows. In the known technical solution, the plate installed inside the cylindrical drum does not allow to clamp a large amount of the processed product at the same time, the fastening of this product is unreliable, which is why the product placed in the drum is torn out. In addition, it does not completely wear out the product, which must be removed from the drum, which takes time. Consequently, the performance of the device is reduced, while the efficiency of the operation is reduced.

In the claimed technical solution, the abrasion of the product is carried out simultaneously with knife blocks on both sides, the amount loaded in

the drum at the same time the product is limited only by the dimensions of the drum itself. In addition, the product placed in the drum is abraded to the end.

The inventive device can be used for other technological operations, for example, for squeezing juices from fruits, for rubbing cooked vegetables, if the device uses disks of different designs without knife blocks, change the rotation speed of the drum and use a mesh and a cover with a hole below to exit the product. Therefore, the technological capabilities of the device are expanding.

On the slider 14, the middle 15 and left 16 are rigidly fixed with vertical struts, externally covered by a casing 17 and fastened rigidly between themselves by stitches 18 (Figs. 1 and 28). On the middle vertical strut 15 there are sockets in which gears-satellites 20 are mounted on bearings 19 (Figs. 1 and 6). These gears-satellites 20 are driven into rotation by a gear-cover 21 connected to them in a kinematic pair, mounted on the grooves 22 located on the left end of the drum 3 (Figs. 1, 4 and 5). During its rotation, the gear cover 21 abuts against the stop rollers 23 mounted on the middle post 15 (Fig. 1). In the center between the gears of the satellite gears 20, also in the nest on the middle strut 15, on the bearing 24 and in engagement with the teeth of the gears of the cover 21, the gear 25 is fixed kinematically connected to the gears of the satellite gears 20 and rotated to the side. opposite to the rotation of the drum 3 with the disk 9 and the knife blocks 10. The gear 25 has an opening with grooves-slots in which the shaft 26 is mounted with the slots 27 of the holder 28 with the possibility of movement (Fig. 1 and b). The holder 28 has slots 29 in which the left vertical disk 9 with the knife blocks 10 is mounted. The movement of the holder 28 with the disk 9 is carried out by means of springs 30 fixed at one end to the left vertical strut 16 and the other end to the ring 31 mounted freely on the splined shaft 26 of the holder 28. The shaft 26 is also provided with an abutment 32 to limit the movement of the holder 28 so that the disks 9 with the knife blocks 10 do not engage with each other after completely abrading the food product placed in the drum 3 and is equipped with a nut. Outside, the left end face of the spline shaft 26 of the holder 28 is covered by a cap 33. A container 34 is installed under the drum 3. On the middle vertical wall 15 are all sockets, with bearings 19 mounted there with gears-satellites 20 and a bearing

24 with gear 25 closed by a cover 35 (Fig. 1).
