Description

The invention relates to kitchen tools and is intended for cutting soft products.

Known similar tools, see.with. USSR No. 1729472 or US Pat. RF №2113980. Some of them work well, but they are difficult and expensive, and they are difficult to wash. Others have a less complex design, but are also less productive, and also difficult to wash.

OPTION 1. This shredder contains a handle in which parallel or fan-shaped knives located below the handle level are fixed at the same level with the blade facing down (hereinafter, all directions are given relative to the conditionally working position of the shredder when it touches a horizontal cutting board with its knives) . See FIG. 12.

To the handle does not interfere with the work, the knives have a corner or T-shape.

To obtain uneven slices of products, the knives can be arranged, as mentioned above, with a fan facing back or forward, and / or can be located at different distances from each other (if the knives are fan-shaped, the distance between them is considered in their middle or along the attachment line in the pen), that is, with different steps.

For the same purpose (so that the pieces stick together less in the salad), the knives can have a zigzag and / or wavy shape, and with a different period of zigzag or wave.

For better cutting of products on an uneven board, the knives can have a rounded, convex shape (like most ordinary knives). But for a flat cutting board, this will only complicate the operator’s work and reduce labor productivity and cutting quality.

For a better distribution of operator efforts, the handle may have a separate emphasis for the thumb, and it is desirable that it “hangs” over the knives, see FIG. 12.

However, the handle can also be vertical, that is, the shredder will resemble a “crush” (rolling pin with an extension below). Which handle to choose is a matter of taste. For a flat cutting board, a handle more inclined at an angle of 10-15 degrees to the horizontal, as in FIG. 1. With such a handle, it is easier for the operator to control the full fit of the knives to the cutting board and easier to control this position.

A shredder may have a ball joint or a Hook joint of limited mobility between the vertical handle and knives (approximately + -5-10 degrees per side). Knives with a vertical handle can have a T-shape (with an inclined handle this is undesirable, since fingers can touch the back of the knives).

The design of the shredder may resemble a regular knife, that is, the blades are molded into a durable plastic or aluminum handle. But another design is possible - more complex, but also more durable - the shredder has one or two transverse knives to which the mentioned knives are attached (one transverse knife is enough, in this case the knives in plan will resemble the letter Ш), and to one of which or a handle is attached to both. See FIG. 3.

In FIG. 1, 2 shows such a shredder, where 1 is the corner knives turned with the blade down, 2 is the handle, 3 is the emphasis for the thumb. To attach the knives there is a traverse 4, which is part of the handle.

In FIG. 3 shows a transverse knife 5 made of thicker steel, to which the knives 1 are attached by contact welding. The transverse knife is attached from above to the plate 6, which is the armature of the handle 2.

The idea of a shredder came about when, because of my haste, I didn’t cut the ingredients for the Olivier salad, but simply crushed the boiled potatoes, eggs, sausage, and sliced pickles with a fork. And even chopped onions. From this it is clear that the shredder works like this: the handle 2 is taken in the hand so that the thumb rests on the stop 3, and with crushing movements, the products are cut into pieces resembling cubes - at first several movements are carried out in one direction, and then in approximately perpendicular direction. The presence of a different step between the knives, the presence of a fan-shaped, wavy or zigzag shape makes the pieces unique in complex shape and size, so that they do not stick together in the salad. But, as always, achieving the maximum result is not always advisable - the presence of waviness and zigzag will increase the sticking of food products between the knives, and will complicate the subsequent washing. Therefore, their feasibility should be evaluated empirically.

The most optimal parameters: the knives are straight, the number of knives is 6 or 7, the distance between the knives is 7-8-9 mm (in the middle - less), the length of the knives horizontally is 60-80 mm, the height of the handle above the cutting board is 30 mm, small is possible fan-shaped knives in 2-3 degrees.

And there is one non-obvious nuance - it would seem that corner knives for reasons of strength can be made almost triangular in the lower part, but in this case it will be difficult for the operator to set the shredder in a position parallel to the cutting board, because it is visually oriented along the visible upper edge of the horizontal section of the knives. Therefore, the knives must have the shape shown in FIG. 1. This shape is easily obtained by cutting without the remainder of a flat workpiece by guillotine or laser cutting.

This shredder not only has good usability and high performance, but, most importantly, it allows you to perform all operations on a regular smooth kitchen board without the need for special covers, containers, devices, etc., and then the shredder is soaked for about half an hour and easily washes with a brush. To clean the shredder from food residues, you can walk with a solid object along the tips of the knives - they will bend slightly, and then straighten sharply, which will cause shaking of the food residues. Or you can turn the shredder upside down with your knives and lightly tap the handle on the edge of the dish.

CUTTING BOARD for option 1. This shredder is intended mainly for making salad from boiled, salted or pickled vegetables and soft sausages - such as Olivier salad, vinaigrette and the like (from canned fish, crab sticks, spinach, green beans, seaweed, Chinese cabbage, etc.). But it can also be used for cutting more durable products - meat, fish without bones, cabbage, etc. To this end, the cutting board has parallel longitudinal grooves of a triangular shape in cross section, and the upper edges of the resulting ridges have teeth. Moreover, it is desirable that the teeth were inclined unidirectional. This will better hold the food and make it easier for the food to slide off the board.

It should be noted that a shredder for working in tandem with such a board cannot have a different step between the knives, fan-like, wavy or zigzag. Knives should only be parallel and at the same pitch.

In FIG. 4, 5 in transverse and longitudinal sections shows such a board, in FIG. 5, inclined teeth 7 are visible.

The shredder works on such a board in a slightly different way - with longitudinal reciprocating movements, the products are cut, not choked. A cross knife in such a shredder is undesirable.

OPTION 2. When grinding products, they can fall off the cutting board under the action of knives. Therefore, this version of the shredder contains a handle in which parallel or fan-shaped knives located below the handle level are fixed with the blade facing downward, the blade of the knives being in the same convex downward facing of an imaginary spherical surface.

The knives, as in option 1, can have different transverse steps, can be wavy or zigzag, and can have one or two transverse knives.

CUTTING BOARD for option 2. This board has the form of a concave spherical surface of the same curvature as the surface in which the blades of the shredder blades according to option 2 are located.

This combination of shredder and cutting board works like this: in any place where the shredder is in contact with the cutting board, with the correct orientation of the shredder, all knife blades always touch the surface of the cutting board without any gap. The presence of a ball joint facilitates the orientation of the shredder (forgives errors up to 5-10 degrees).

In this case, one positive quality of the shredder is lost according to option 1 - no other special devices are required, except for a simple flat cutting board. But another, more valuable positive quality is acquired - if you give the cutting board sufficient curvature and arrange it in the form of a spherical plate with an annular counter, then when preparing one portion of the salad, you can eat it directly from this plate. Perhaps for such a board, a shredder with a vertical handle, or at least with a handle more steeply raised in the back, is more convenient - up to 25-30 degrees (so as not to touch the board and products with the handle and hand). For a vertical handle, a T-shaped knife is preferred.
