Description

The invention relates to technological processes associated with grinding fruits and vegetables.

Known grinder of fruits and root crops, containing supports, a cylindrical body, a loading hopper fixed on it with a vibrator-shaker, a drum-type dispenser having a flap valve in the lower neck, a centrifugal rotor with three guide pipes located at an angle of 120 ° relative to each other, an electric motor , while inside the cylindrical body there is a knife body in the form of a truncated sphere formed by arcuate knives, as well as upper and lower discs fixed to each other by means of tie bolts, the knife body is equipped with reflectors, the centrifugal rotor rotates inside the knife body; the protective casing is fixed between the lower disc and the lower part of the cylindrical body, and the container for collecting the crushed product is made individually, located under the unloading holes of the cylindrical body [RF patent for useful model No. 163146. Published on July 10, 2016. Bul. No. 19].

The disadvantage of this device is the high complexity of adjusting the installation of knives relative to the centrifugal rotor, depending on the crushed fruit and vegetable products.

The closest in terms of the aggregate of essential features is a fruit and vegetable chopper, containing supports, a cylindrical body, a loading hopper, a vibrator-shaker, a dispenser with a rocker valve in the lower neck, a centrifugal rotor with guide pipes, an electric motor, a protective casing, reflectors, a container for collecting chopped product, replaceable knife walls with knives, reflectors [RF patent for utility model No. 174962, Published on 11/13/2017. Bul. No. 32].

The disadvantage of this device is the low technological reliability of the structure due to the high probability of clogging the guide pipes with large fruit and vegetable products, which leads to stoppages of the fruit and vegetable chopper in order to clean the guide pipes. The use of guide pipes, which ensure the passage of fruit and vegetable products with a significant variation in size, leads to an increase in the rotating mass, and, consequently, to an increase in engine power and an increase in electricity consumption.

The essence of the invention is as follows.

The objective of the invention is to reduce energy costs for grinding fruits and vegetables.

The technical result is an increase in the technological reliability of the design of the grinder of fruits and vegetables.

The specified technical result in the implementation of the invention is achieved by a fruit and vegetable chopper containing supports, a cylindrical body, a loading hopper, a vibrator-shaker, a dispenser having a flap valve in the lower neck, a centrifugal rotor with guide pipes, an electric motor, a protective casing, reflectors, a container for collecting chopped product, replaceable knife walls with knives, while the loading hopper is additionally equipped with a replaceable sieve installed at an angle towards the opening for the outlet of substandard fruits and vegetables, made in the wall of the feed hopper with the possibility of overlapping with a damper, while the interchangeable sieve is fixed with a lock on the feed hopper, to to which a pitched board is connected by means of a suspension, which ensures the supply of substandard fruit and vegetable products to an additional hopper, and the guide pipes are replaceable, while the diameter of the flow section of each guide pipe corresponds to the size cells of the replaceable sieve.

The essential features influencing the achievement of the claimed technical solution are:

- equipping the loading hopper with a replaceable sieve,

- making an opening in the wall of the loading hopper for the exit of large-sized fruits and vegetables,

- equipping the loading hopper with a flap for closing the opening for the exit of large-sized fruits and vegetables,

- installation of a replaceable sieve with an inclination towards the opening for the exit of large-sized fruits and vegetables,

- fixing the replaceable sieve with a latch,

- attachment to the loading hopper of the pitched board by means of a suspension,

- execution of guide pipes replaceable,

- correspondence of the diameter of the flow area of each guide tube to the size of the cells of the replaceable sieve.

The essence of the invention is illustrated by drawings, where FIG. 1 shows a diagram of a chopper for fruits and vegetables, Fig. 2 - section a-a in Fig. 1, fig. 3 - Drawings of replaceable guide tubes of two standard sizes.

The fruit and vegetable chopper contains supports 1, a cylindrical body 2, a loading hopper 3, a vibrator-shaker 4, a dispenser 5 having a rocker valve 7 in the lower neck 6, a centrifugal rotor 8 with guide pipes 9, an electric motor 10, a protective casing 11, reflectors 12, a container 13 for collecting the chopped product, replaceable knife walls 14 with knives 15, while the loading hopper 3 is additionally equipped with a replaceable sieve 16 installed at an inclination towards the opening 17 for the outlet of substandard fruits and vegetables, made in the wall of the loading hopper 3 with the possibility of overlap with a gate 18 , while the replaceable sieve is fixed with a retainer 19 on the loading hopper 3, to which a pitched board 21 is attached by means of a suspension 20, which provides the supply of substandard fruit and vegetable products to an additional hopper 22, and the guide pipes 9 are replaceable, while the diameter of the flow section of each guide pipe 9 corresponds to the size of the shift cells foot sieve 16.

The chopper of fruits and vegetables works as follows.

Before loading fruit and vegetable products into the loading hopper 3, guide pipes 9 are installed, the diameter of the flow section of each of which ensures the passage of a larger share (at least 50-60%) of the crushed fruit and vegetable products, and a replaceable sieve 16 with cells, the minimum size of which is 10-15% larger than the diameter of the flow section of the guide tube 9, fix the replaceable sieve 16 with the lock 19 on the loading hopper 3. Then start the electric motor 10 to set the centrifugal rotor 8 to the required speed. The shredded fruit and vegetable products are loaded into the loading hopper 3 on a replaceable sieve 16. They include a vibrator-shaker 4. Fruits or vegetables with dimensions smaller than the openings of the replaceable sieve 16 enter the drum-type dispenser 5 and then into the centrifugal rotor 8. By transferring torque by the shaft electric motor 10 centrifugal rotor 8 evenly distributes fruit and vegetable products along three guide tubes 9. As a result of centrifugal force, material is removed from the guide tubes 9 through the knives 15 of the knife walls 14 at a linear speed required for complete cutting. At the same time, fruits and vegetables penetrate through the knives 15, crushed into slices of the required thickness and then through the reflectors 12 and are unloaded into the container 13 to collect the crushed material.

After stopping the grinding of the incoming fruit and vegetable products into the centrifugal rotor 8, open the gate 18 and substandard fruit and vegetable products, i.e. the one that did not pass through the cells of the replaceable sieve 16 enters through the hole 17 along the sloping board 21 into the additional hopper 22.

Then another replaceable sieve 16 with large mesh sizes and another set of guide pipes 9 with corresponding flow sections are installed in a similar way. Substandard fruit and vegetable products from the additional hopper 22 are poured into the loading hopper 3. The process is repeated.

Thus, the declared fruit and vegetable chopper increases the technological reliability of its design.
