Description

The invention relates to processing industries, to canning, winemaking and non-alcoholic, in particular to methods and devices for separating juice and wine from coarse suspensions.

The aim of the invention is to increase the efficiency of the cleaning process and the quality of clarified juice and wine by self-cleaning, self-regeneration of crevices, gaps of a perforated surface (grating).

The goal is achieved in that in the method and device for separating juice and wine from coarse suspensions, the feed is provided tangentially, in the form of a thin film pulsating with a frequency of at least 60 pulsations per minute at a depth of not more than 1/10 of the height of the perforated workers chambers, representing the shape of the surface of rotation of the second order: hemispheres

(figure 1), its sections (figure 2, 3); cone of rotation (Fig. 4): its sections (Figs. 5, 6); a semi-ellipsoid of elongated rotation (Fig. 7); its sections (Fig.8.9); a semi-ellipsoid of rotation of the compressed (Fig. 10), its sections (Figs. 11, 12), as well as other varieties of such surfaces, the schematic diagrams of which are not shown.

Mathematically, these surfaces are described by the following formulas:

2) cone of rotation

6) two-sheeted hyperboloid

The gaps of the grating (perforated surface of the working chamber) are through slots with a width of no more than 0.1 mm, which are formed by trapezoidal strips, the sides of which copy the shape of the working chamber created by them, i.e. are the same half-surfaces of rotation of the second order and are located at an angle to the longitudinal axis of the shell.

Improving process performance and cleaning quality of products is ensured by self-cleaning the gaps of the grating by the flow itself, which is supplied tangentially and pulsating in a thin layer, which allows the flow to continuously separate into two parts: a clean clarified liquid that passes through the grating of the grate and is collected under the working chamber and hard particles, which, due to the shape of the working chamber, roll in the direction of its lower part, and the remaining pulsing particles are washed off and moved downward by the next pulsating product stream the one also in the lower part of the working chamber. The solid particles separated and collected in the lower part of the working chamber are then sent in accordance with the developed technology, for example, to a shaker, where they are mixed with pulp and then pressed into a press to extract juice or wine from them or pressed directly in a press together with a glass pulp filed out of stackers.

The method is carried out as follows.

Separated juice from pulp or wine, treated with adsorbents and / or gluing materials, is lodged in a perforated working chamber formed by trapezoidal slats at a height of 1/10 of its height tangentially. The pulsation of the flow is carried out by one

of known methods, for example a flow interrupter. At the same time, at least 60 pulsations per minute are created. Due to this, the liquid passes through slits with a width of not more than 0.1 mm of the lattice (working chamber), and the solid particles remaining on the inside. surface of the working chamber or roll down independently under the action of gravity and its own weight or

0 are washed away from the inner surface by a pulsating flow. The liquid separated from the solid particles is collected separately under the working chamber, and the solid particles accumulating in the lower part of the grating are either mixed with the pulp in the stacker or fed to the pressing together with the draining pulp. Thus, a waste-free technology for clarifying juices and wines with minimal energy costs is realized (practically only one pump and a device are used to create pulsations in the flow). The continuous flow of the initial product does not have shock and vibrating force, unlike pulsating, which does not allow to keep the perforated working chamber constantly clean and tear off solid particles adhering to it from its inner surface. Figure 1, .. 15 shows a General view

0 of the proposed devices in the context to better show the design, as well as cross-sections of the trapezoidal slats forming the working chambers and slots, and their longitudinal view

5 The device for separating juice and wine from coarse suspensions contains a housing 1 for collecting clarified liquid, a nozzle 2 for removing solid particles, a nozzle 3 for removing clarified liquid, a perforated working chamber 4 formed from trapezoidal slats 5, a chamber for supplying the initial product 6 representing in shape a mirrored working chamber and hoops 7

5 forming working chambers.

Example. Grape wort obtained on the instrument-technological lines VPL-20, VPL-20K, VPG-30 and others is fed into the working chamber of the device by a centrifugal pump of the VTsN-20 brand. Between the pump and the device for separating coarse suspensions, a flow breaker of known design is installed, which provides pulsation of the flow with a frequency

5, of the order of 100 pulsations per minute, the direction of the pulsating flow into the working chamber is carried out by chamber 6, which, thanks to its shape, provides a tangential supply of the initial product to the working chamber at a depth of 1/10 of its height,

in the form of a pulsating film, which makes it possible to distribute the flow evenly over the entire perforated surface of the working chamber and significantly increase the productivity of the installation. Suspended grape must, having a size of not more than 0.1 mm, falls through the sieve and collects inside the housing 1, and through the pipe 3 is sent for further processing according to technology, for example, to a separator for final clarification. Coarse suspensions with a size of more than 0.1 mm roll down the inner surface of the working chamber, accumulate in its lower part and are sent through pipe 2 for further processing either to a stacker or to a press.

EXAMPLE 2, Wine material treated with gluing materials, for example bentonite and gelatin (the doses of gluing materials are determined by trial gluing in accordance with the technological instructions) are mixed well, then left for 30 minutes to form flocs (possible and stream processing of wine materials gluing agents), and then the PMN-28 pump is fed through the device to create pulsations to the flow in the chamber 6, and from there tangentially, in the form of a film on the entire inner surface of the perforated working chamber The cells where wine material with solid particles, having sizes up to 30 microns are filtered through a sieve, is collected inside the housing 1 and sent through the pipe 3 for final clarification, either for separation or for filtration. The formed flocs separated from the liquid accumulate in the lower part of the working chamber and are sent through the pipe 2 to either filtration or pressing to extract wine material from them and obtain precipitation with a minimum moisture content (not more than 50%).

In the described method and device for separating juice and wine from coarse suspensions

provides intensification and increase in productivity of the process, as well as improving the quality of clarified products as a result of uniform distribution

flow in the form of a film and self-cleaning perforation of the working chamber due to the tangentiality and pulsation of the initial product. In addition, a virtually waste-free juice processing technology is provided.

and wine materials, clogging of the inter-tray space of the separators with solid particles is eliminated, and thereby the separator operation is achieved almost without disassembly for a very long time

time during the final clarification of products.

The proposed method and device provides an increase in the productivity of the process by 2 ... 3 times compared with

known by similar processes, it is not necessary to periodically clean the perforation of the working chamber, allows to obtain slits with a width of less than 0.1 mm, and are structurally and technologically simple to manufacture.
