Description

one

The image refers to devices that are days old and used in the food industry in the processing of tea leaves.

The purpose of the invention is to reduce energy costs and improve the quality of tea by reducing its abrasion.

On fpg. 1 shows a schematic diagram of a tea bag; FIG. 2, section A-A in FIG. I.

The proposed device for drying tea contains a torpus 1, inside of which a perforated inclined drum 3 is installed with the possibility of scattering on a roachik.x 2 from a drive (not shown). The drum 3 is made conical with um. the end of On the inner surface of the drum 3, there are choles 4, the height of which decreases towards the discharge head, in such a way that the edges 3 facing the center of the drum 3 are parallel to the axis of the drum. Inside the drum 3, a device for leveling the layer of the product, consisting of an endless hardening tape 5, an interlocking sprocket 6 and a fixed curved plate 7, is installed eoosno with im.The case 1 N. exhaust air. In the lower part of the housing 1 along the Barbara 3, the razolozheya screw 10 is used for unloading small particles of tea. To guide the air xx, there are partitions 11 and 12 in the device, as well as covers 13 and 14 located on the ends of Corsus I. The device is loaded. 1 by feeding the metering hopper 15 through the nozzle 16, and unloading the dried product through pipe 17.

The size of the gap between the drum 3 and the perforated .rent 5 from the side zag) of the narrow nozzle 16 is 2.5 ... 3 times the length: the first is this gap from the unloading side and the pipe 17

The device works as follows.

The tea to be dried is loaded into the dosing unit 15, from which it flows into the drum 3. At the same time, hot air is fed into the device through the nozzle 8. To the drum 3, the particles of the cup are grabbed by the liasts 4 and are transported into the gap between the perforated drum 3 and the endless perforated tape 5 n |) mechanical flex to level the product layer. Mass of China, rising between rotating horned drum 3 and moving infinite non-surfacing mite 5 and then feeding on oi-i-bath with a tape of 5 ver. The Iloe.ie of this tea mass is again picked up by the chains 4 and HHK. I repeat. Due to the fact that the perforated belt 5 on the curved section and the perforated drum 3 are moving without relative weight, the design is prevented

Feel the condition of rubbing tea mass, which improves the quality of the final product.

In the process of drying, a gradual decrease in the volume of tea mass occurs 2.5 ... 3 times. In order to prevent unjustified consumption of heat-transfer fluid.h when drying and to reduce energy consumption, drum 3 has been made to decrease. the diameter towards the discharge pipe 17 so that the gap between the drum 3 and the non-perforation tape 5 from the side of the loading pipe and the 16 pipe 2.5 ... 3 times exceeds the value of this gap from the discharge pipe 17, which It reduces the volume of the tea mass and creates favorable conditions for carrying out the drying process.

Fine particles of tea, other than others through the perforated belt 5 due to the inclination and movement of the belt 5, are advanced to the discharge end of the device and are discharged through the pipe 17, and that part of the small particles that passed through the perforated drum 3 is semicom 10 fed into the pipe 17. The bulk of the product passes inside the drum 3 and is discharged through the nozzle 17.

This device is used to prevent the abrasion of tea mass and improve the quality of the finished product, as well as intensifying the process while reducing energy consumption due to leveling the layer along the entire length of the device and creating the same conditions for the drying agent (air).

Claims (1)

Invention Formula A superstructure station, including a case, installed in a new type with a possibility of a hardened inclined drum with blades on its inner surface, inlays for loading and unloading and exhausting air, loading and unloading tea, and a device for leveling, expanding The drum along its entire length on the side of the pipe for the supply of air, made in the form of a curved ilastina, characterized in that, with the aim of cutting 1. energy consumption and improving the quality of tea, and with its abrasion, the perforated drum of about. a device for leveling the layer of the toig from the envelope plaster of the bee-point non-perforated tape installed with the possibility of alternation 1, which is the size of the gap between the drum and the perforated mite from the side of the charging pipe in 2.5 ... 3 times the value of this gap on the side of the unloading pipe. 7 / ////////// 2
