Abstract

FIELD: food industry.SUBSTANCE: invention relates to means for grinding plastic substances and can be used for grinding food, in particular, meat products. Grinder comprises one or more sets of movable blades and rotary working table. Set of movable blades consists of two blades in the form of cutting knives, and rotary work table is made in form of rotating on axis of flat tabletop, on which products are ground. In each set, blades and movable partitions move along circular reciprocating trajectory to opposite sides along working table along one line with possibility of common cutting of product from center to edge of table at working stroke on fixed working table and synchronous lifting of blades of each set towards center of table with subsequent lowering onto working table. At that, when the blades are lifted and returned to the beginning of the working stroke, the working table is turned to the specified angle to displace the cutting-grinding line from the previous one by the specified angle. Additionally on the working table there are limiters of working space in the form of vertical partitions – two fixed side and two movable partitions fixed on the rotary axis on the non-working side of the blades for returning to the center of the working table of the ground substance, which in the working stroke is moved by blades from the center of the working table to its edges. Mechanism can be driven from geared motor via crank-and-rod mechanism.EFFECT: grinder allows to preserve structure of product due to prevention of crushing or breaking of its structure in process of grinding.1 cl, 17 dwg

Description

The field of technology to which the invention relates: food and non-food industry, cooking at home and at catering, sparing without destroying the structure grinding plastic or non-solid raw materials.

The level of technology: a special independent device operating in a cycle - loading, grinding, unloading.

As analogs it is necessary to consider a screw grinder or blender.

Disclosure of the invention: Cyclic, reciprocating chopper plastic substances. In the future, the device. Intended for: grinding plastic or non-solid food substances of both animal and vegetable origin, as well as non-food substances. The main purpose is to crush without breaking the structure, cutting up to the necessary fraction of meat products. Obtaining the required fraction - the size of the pieces in the finished product is provided by the number of grinding mills - the duration of the processing period, which can be set arbitrarily. The processing, which is sparing without destroying the structure, is ensured by the absence of hard gripping and forcing raw materials in the device through a grid like an analogue of a meat grinder, or multiple chopping - breaking blows with knives moving at high speed destroying the structure of raw materials like an analogue of a blender type. All this allows the device to maintain the original quality of the raw material after grinding - inaccessible analogues. In essence, this invention is the mechanization of the manual method of cooking minced meat that has emerged from use, with the simultaneous use of two ordinary kitchen knives by one person on a conventional cutting board.

The implementation of the invention: Design - the device consists of a rectangular frame body 1 in the shape of a parallelepiped. On the case there is a motor - reducer 2, which rotates the crankshaft 14 through the axis 20. Additionally, the motor - reducer 2 through its internal partially gear gear, performs intermittent specified angular movements of the desktop 4 in the return stroke of the blades 7 acting on the gear 9 of the working axis 9 table 4. The crankshaft 14, rotating - moves the connecting rods 13 the second side of the connecting rods 13 moving along the guides 6 of the carriage 3 is fixed on the axial-rotary lever 10. Persistently-the rotary lever 10 has a complex purpose, when passing the connecting rods and 13 extreme points, the vector of the impact of rods 13 on the thrust levers 10 are reversed, when changing the direction of the influence of the stubborn levers 10 rotate the axes 12 bearing movable end walls 22 and the blade 7, at a given angle. Further rotation of the crankshaft 14, leads to the movement of the carriages 3 that slide on the guide carriages 6. Axes 12, pivoting movable partitions 22 and blades 7 move along with carriages 3 and fixed side partitions limiters of working table 5, necessary for the fact that the crushed raw material does not go beyond the area of the working stroke of the blades 7. To rotate the working table, the device 1 has a sleeve 11, into which the axis 8 of the table 4 enters and rotates in it. To create a constant pressure of the work table 4 to the fixed side partitions limiters of the space of the work table 5, the second purpose of the spring 17 makes it possible to lower the work table 4 to perform the operation of loading raw materials or unloading the finished crushed raw materials. For rigidity and to avoid backlash of the rear carriages 3 from the front carriages 3, they are connected by plates 21. The arc-shaped solid arrow 15 shows the direction of rotation of the crankshaft - it is constant except for the loading - unloading operations of the device - when the rotation is stopped. Solid straight arrows 16 show the upcoming direction of movement of the carriages 3, in the case of when the carriages change the direction of movement two arrows are shown in different directions. The arc-shaped solid arrow 18 shows the upcoming direction of rotation of the pivotal lever 10. The arc-shaped solid arrow 19 shows the forthcoming direction of rotation of the desktop 4.

The principle of operation of the device - In FIG. 1 side view, shown - the device is in the position of the end of the stroke, while the blades 7 are lowered onto the working table 4, in fact the blades have finished making the cut, the carriages 3 are extended to the outermost positions. The arrows 16 show that the carriages 3 will change direction. FIG. 2 shows the same position of the device as in FIG. 1 except for the side fixed partition 5 which is not shown for illustrative purposes. FIG. 3, a side view shows the continued operation of the gear motor 2 and the rotation of the crankshaft 14, with the crankshaft 14 starting to pull the connecting rods 13 inwards and which, acting on the pivotal levers 10, rotate the axles 12 bearing movable end partitions 22 and the blades 7. When turning axis 12, - the blades 7 are lifted from the working table 4, and the movable pivoting partition 22 is lowered onto the working table 4. The device is ready for the return stroke. This position, further shown in section in FIG. 8 is a top view, FIG. 11 is a sectional side view; and FIG. 13 is a side view in section. FIG. 4 shows the continued operation of the gear motor 2 and the rotation of the crankshaft 14, the carriages 3 are returning along the guides 6, move the axes 12 to the middle of the table 4, the movable end partitions 22 are lowered onto the work table 4 —and push the raw material stretched by the blades into the center of the table 4 , the blades 7 are raised from the table 4, the table 4 rotates on its axis 8. The rotation of the table 4 occurs only when 4 blades raised from the table 4. In FIG. 5 shows the continued rotation of the crankshaft 14, the end of the return stroke, the connecting rods 13 are retracted and will change direction. FIG. 6 and shows the continued rotation of the crankshaft 14, the connecting rods 13 began to push hard-pivot levers 10, the levers 10 turned along with the axles 12 and lowered the blades 7 on the table 4, the partitions 22 rose from the table - the device is ready for operation, this position is additionally shown in fig. 9 is a top view, FIG. 10 is a sectional view from the end side and in FIG. 12 is a side view in section. FIG. 7 shows the continuation of the rotation of the crankshaft 14, the execution of the working stroke, while the blades 7 are lowered onto the working table 4, the connecting rods 13 continue to push the stop-swivel levers 10 - which are now pushing the carriage 3 along the guides 6 by moving the raised partitions 22 and the lowered blades 7 on the table - Blades make a cut of the substance. Further rotation of the crankshaft 14 leads the carriage 3 to the position shown in FIG. 1. Everything repeats again, repeatedly until motor - gearbox 2 rotates the crankshaft 14. In case the grinding process is over, it will be necessary to stop the motor - gearbox 2 at the end of the stroke, lower it down due to the vertical stroke of the axis 8 in sleeve 11 on spring 17 table 4, lift the blades 7, table 4 due to the spring 17 will rise and lock the blades in a vertical position for the operation of unloading - loading as shown in FIG. 14 and FIG. 15 in the context of the side. For clarity of understanding the operation of the device, the trajectories of movement of the cutting edges of the blades 7 are shown — in FIG. 15, the movement of the left blades 7 and in FIG. 16, the movement of the right blades 7 is a side view, —paths of the trajectory 31 and 41 correspond to the working strokes, the portions of the trajectory 32 and 42 correspond to the preparation for a return stroke — raising the blades from the table, the portions of the trajectory 33 and 43 correspond to the return stroke; to the working stroke, the lowering of the blades to the working table 4, the path section 35 and 45 correspond to the operations unloading - loading.

Notes - two oppositely located blades performing a cut along one line are called a set - blades 7, the number of sets - blades 7 in the device as well as the stroke of the carriages 3, and the dimensions of table 4 will depend on the required performance of the device - in this case the device with two sets is shown - blades 7.

Cyclic, reciprocating chopper plastic substances. Explanatory note.

Cyclic, reciprocating chopper plastic substances - hereinafter device. Application of the device can be found both in every kitchen and in various food industries. The need for an invention arose from the fact that in fact in our time, people are weaning off manual labor everywhere, this process is so important for us as cooking is not circumvented. Personally, I still remember a time when, despite the presence of a meat grinder, minced meat was prepared in a laborious manual way - a person who had the necessary skills and patience took a knife in each hand and made simultaneous cuts on a cutting board in divergent directions in opposite directions, occasionally returning by moving the knives flat stuffing to the center. With this method, the quality of the original product was completely preserved in cooked minced meat, in fact the smallest piece in this minced meat remains a small piece of meat. Currently, the use of meat grinders and blenders leads to the fact that the initial quality of the product is lost, the initial product is crushed, broken down - turns into puree - shaped mass. Naturally, no one will return to the manual method of cooking minced meat, but everyone wants to use high-quality cooked products. Therefore, a cyclic, reciprocating chopper of plastic substances - this is actually the mechanization of the described manual process - can be widely demanded.
