Abstract

FIELD: food-processing industry. SUBSTANCE: the invention presents a device for comminution of the food vegetable raw materials at production of different purees and juices. The device for comminution of the food vegetable raw materials contains the metal millstones with the abrasive coating applied on their working surfaces and a working area executed in the form of a truncated cone, the runner of which is installed with a capability of motion along its axis of rotation between the upper and lower limiters. On the lower millstone there is a rigidly fixed sieve made in the form of a perforated ring, At that a slider mounted on the shaft of rotation from the side of the runner leans against the upper limiter. On the slider there are pivotally mounted levers, one of the ends of which loosely touches the runner, and on the second end there is a load with a capability of motion along the axis of the lever. The invention allows to intensify the process of the food vegetable raw materials comminution. EFFECT: the device allows to intensify the operation of the food vegetable raw materials comminution. 3 dwg

Description

The invention relates to the food industry and can be used for grinding edible vegetable raw materials upon receipt of a variety of mashed potatoes and juices.

Known devices for grinding plant materials that implement a wide range of physical effects for separating particles of various shapes and sizes from the processed object [1].

Upon receipt of various kinds of vegetable purees and juices, the known devices do not completely destroy the structure of the processed raw materials, which does not allow to isolate the maximum possible amount of dietary fiber and cellular juice.

The closest in technical essence and the resulting positive effect to the claimed is a device with working bodies containing metal millstones with abrasive coatings applied to their working surfaces and a working area made in the form of a truncated cone [2].

The described device due to the application of an abrasive coating on metal millstones allows more deeply destroy the structure of processed food raw materials, separating a greater amount of dietary fiber and juice. At the same time, the lack of the possibility of rapprochement of metal millstones and insufficient clamping of raw materials to abrasive surfaces leads to the fact that, under the action of centrifugal forces, sufficiently large particles of the raw material are removed along with the juice contained in them.

The aim of the proposed technical solution is to make fuller use of crushed plant materials and to increase the consumer properties of the resulting products.

To achieve this goal in a device for grinding vegetable raw materials containing metal millstones with an abrasive coating applied to their working surfaces and a working zone made in the form of a truncated cone, the upper millstone is installed with the possibility of movement along the axis of rotation between the lower and upper limiters, and on the lower a sieve in the form of a perforated ring is rigidly fixed to the millstone, moreover, the upper stopper is supported by a slider mounted on the rotation shaft from the side of the upper millstone, on which it is articulated levers are installed, one of the ends of which freely touches the upper millstone, and on the second a load is installed with the possibility of movement along the axis of the lever.

The technical effect in the claimed device is realized due to the fact that the vertical movement of the millstones relative to each other allows for a more intense impact of working abrasive surfaces on the crushed raw materials by means of an additional clamp. This leads to finer grinding and additional separation of dietary fiber and juice. The presence of a sieve in the form of a perforated ring enclosing the working area allows, on the one hand, to retain large fragments of the separated raw materials in the grinding zone, and on the other hand, to squeeze out the allocated juice. The presence of articulated levers allows you to adjust the clamping force for various types of raw materials and different modes of processing due to the movement of goods along their axis.

In Fig.1 shows a schematic diagram of the device, and in Fig.2 and Fig.3 - cross-section of its horizontal plane in the installation area of the most critical structural elements.

The device consists of an upper metal millstone 1 and a lower metal millstone 2 with an abrasive coating applied on their working surfaces in the form of a binder 7 and abrasive grains 8 and a working zone made in the form of a truncated cone containing a lead-in zone 3 and a grinding zone 4, the upper millstone 1 is mounted on the base 6 with the possibility of movement along the axis of rotation 5 between the lower 9 and upper 10 stops, and a sieve 11 in the form of a perforated ring is rigidly fixed on the lower millstone, and the upper limiter o ert mounted on the side of the upper slider grindstone rotating shaft 12 on which levers 13 are pivotally mounted, one end of which is freely Regarding the metal base 6 of the upper grindstone 1, and the second load 14 is installed movably along the axis of the lever.

The device operates as follows. When the upper millstone 1 with the upper limiter 10 and the slider 12 are removed, the edible vegetable raw material is loaded into the working chamber, including zones 3 and 4, formed by the lower millstone 2 and the sieve 11. On the shaft 5 is placed a metal base 6 with the upper millstone 1, on which as on the lower millstone 2, abrasive grains 8 are installed using a bonding material 7, after which a slider 12 and an upper stopper 10 are installed. The distance of the load 14 is preliminarily adjusted on the axis of the lever 13 depending on the physicomechanical properties and processing conditions from ground raw materials. After loading the raw materials, a drive (not shown) is turned on, which transmits torque through the metal base 6 to the upper millstone 1, which is rigidly fixed on it. The weights 14, under the action of centrifugal force, begin to deviate from the axis of rotation, pressing by means of levers 13 pivotally mounted on the slider 12 to metal base 6 and reporting vertical movement to millstone 1. Edible vegetable raw materials due to the convergence of millstones 1 and 2 are pressed to the working abrasive surfaces and subjected to abrasion by rotating Isya millstones. As grinding under the action of centrifugal forces, the crushed raw materials and the allocated juice are transferred to the sieve 11, through which they fall into the collection tanks. As the vegetable raw materials are ground, millstone 1 gradually approaches the millstone 2. Having reached a certain position, it abuts against the limiter 9, which prevents the contact of two rotating millstones. After the termination of juice separation, the device is disassembled in the reverse order described during assembly, the residual raw materials are removed and reloaded. If necessary, the raw material extracted from the working chamber can be reused, acting as an additional filter for the separated juice.

Using the proposed technical solution will intensify the process of grinding edible vegetable raw materials and ensure its deeper processing with a more complete selection of dietary fiber and juice.
