Description

Tire for roasting unfractionated zhoria or wastewater production waste.

The invention relates to equipment for the production of coffee substitutes and can be used for roasting dried chicory unfractionated by size or wastes of cyclo-drying production in crumbs and fines.

There is a known installation for roasting unfractionated chicory Ш1И of washer-dryer production waste, containing a manual hydraulic press with a form 1 | in the ref.sb.Food industry, series 4 Щ {0servive, vegetable-drying and ripe concentrate industry D983, issue 6, M., TsNIIGEISH, p.).

The disadvantages of this installation are its complex design and low productivity.

Tires for roasting unfractionated zhoria or wastes from a prior art production are not known from the prior art.

The objective of the invention is to simplify the design and increase the productivity of the equipment used.

This problem is solved by the use of a screw plasticizer for processing thermoset materials with fibrous filler, containing a vertically arranged material cylinder with an outlet, a conical loading hopper with a cylindrical neck, along the inner surface of which longitudinal grooves of variable depth with a width are made in the zone of transition of the conical part to the cylindrical neck,

- increasing to connect with adjacent grooves, and increasing towards the material cylinder with a cross-sectional area, a screw with a screw thread, made with a cylinder section located in the material cylinder and a hollow conical section mounted in the loading hopper with the possibility of axial displacement relative to the longitudinal axis material cylinder (USSR author's certificate No. I5I9909, KL.V29S 45 / 46.1989), as a machine for roasting unfractionated chicory or cyclic drying waste dstva.

In FIG. I shows the general view of the machine: in Fig.2 a section of the groove zone; Fig. 3 and 4 grooves with characteristic dimensions.

The tire contains a vertically arranged material cylinder I with an outlet, a conical loading hopper 2 with a cylindrical hole, along the inner surface of which in the transition zone of the conical part in the cylinder neck there are longitudinal grooves 3 of variable depth with a width that increases to connect with adjacent grooves, and increased towards the material cylinder I with a cross-sectional area. The execution of the grooves 3 with an increasing cross-sectional area on the kenic section of the loading hopper 2 (zone P in Figs. I and 2) is achieved by linearly increasing the depth at a constant width and allows better filling of the grooves 3, for example with chicory, ensuring its constant adhesion to the wall of the hopper 2, which prevents it from slipping in the circumferential direction without shifting in the axial direction. On the groove cutting section 3 in the cylindrical neck of the hopper 2 (zone III), the increase in the cross-sectional square foot of each groove 3 is achieved due to

greater cKfpocTH increase in the width of the groove than the rate of decrease in its depth, which allows chicory to pass through the grooves and exit to the material cylinder I without additional resistance to mixing. This simultaneously reduces the load on the turns of the conical section 4 of the screw mounted in the loading hopper 2 with the possibility of axial displacement along the cylindrical section 5 of the screw located in the material cylinder 1, and connected to the drive 6 of rotation by means of a screw thread 7, the profile of which coincides with the profile of the screw thread 8 the cylindrical section 5 of the screw, and fixing by means of two splined joints S and 10 with a different number of splines. The tire also contains receiving chambers II and 12 with hydraulic cylinders 13 and 14 of back pressure mounted at the output of the material cylinder I with the possibility of reciprocating movement in horizontal dances from hydraulic cylinder 15.

When roasting chicory, the machine operates as follows.

Unfractionated sized chopped dried chicory or waste from the circulating dryer production in the form of crumbs and fines from some kind of loading device is fed into the hopper 2. The conical section 4 of the screw rotated from the drive 6 through the cylindrical section 5 and the splined joints 9 and 10 captures the material and mixes it into the area where the cylindrical section 5 of the screw is located. In the upper part of the conical section 4 of the screw (zone I), the chicory particles freely slip relative to each other and to the wall of the hopper 2 due to the lack of sufficient densification.

-

kera 2 increases, and chicory mixes only in the direction of cutting grooves 3 until a seal is reached, at which the adhesion between the particles of chicory will exceed its friction against the screw and the wall of the hopper 2.

In the cutting zone of the grooves 3 on the cylindrical neck of the loading hopper 2 (zone III), an increase in the cross-sectional area of the grooves 3 ensures a free exit of chicory from them and its entry into the material cylinder 1, along which it is transported together with the bulk of the raw material. The cylindrical section 5 of the screw, Directly driven by drive 6.

As chicory is moved by the cylindrical section 5 of the screw along the material cylinder I, it heats up, fries and enters the receiving chamber II. During the set dose, the piston of the counter-pressure cylinder 13 mixes down under the pressure that arose during its formation. When the piston reaches the hydraulic position of the cylinder 13, the rotation drive 6 is automatically turned off, and the receiving chambers II and 12 together with the cylinder 13 and 14 are mixed by the hydraulic cylinder 15 to the extreme right position (dotted line in Fig. I). When the receiving chambers II and 12 are mixed, the molded dose and its pushing out of the receiving chamber II by the piston of the counter-pressure hydraulic cylinder 13. At the same time, a dose is set in the receiving chamber 12, after which the hydraulic cylinder 15 mixes the receiving chambers II and 12 in the left-most position set, in which the ejection of the molded drzn receiving chamber 12 of the hydraulic cylinder 14 and piston set dose receiving chamber II.Dalee cycle repeats.

In practical calculations of constructive design of the hopper 2 in the groove cutting zone 3, the following recommendations should be used for the geometric parameters of the grooves 3. The maximum groove depth 3 N is the minimum width B, the length of the cut on the cylindrical and conical H parts of the hopper 2, as well as the angles of inclination of the grooves 3 on the conical and the cylindrical Y sections of the hopper 2 and the distance a from the connection line of adjacent grooves 3 to their exit to zero depth is chosen taking into account the regularities known for screw plasticizers Lekushe value of the width p aza 3 on the cylindrical neck is determined taking into account conditions:
