Description

II

Изобретение относитс к оборудованию дл обработки чайного листа и может быть использовано в чайной промышленности .The invention relates to tea leaf processing equipment and can be used in the tea industry.

Над более близким решением к изобретению по технической сущности и достигаемому результату вл етс известное устройство дл обработки чайного листа, включающее неподвижный цилиндрический корпус с загрузочным бункером и установленным в нем нагнетающим шнеком с уменьшающимс шагом и увеличивак димс диаметром вала в направлении пере мещени продукта Г - 1 Above the closer solution to the invention by its technical essence and the achieved result is a known device for processing tea leaf, comprising a stationary cylindrical body with a hopper and a delivery screw installed in it with decreasing pitch and an increase in shaft diameter in the direction of product movement G - 1

Недостатками известного устройства вл ютс мала производительность и чрезмерное измельчение всей чайной массы .The disadvantages of the known device are low productivity and excessive grinding of the entire tea mass.

Цель изобретени - повышение эффективности разрушени листовой массы без измельчени грубых стеблей.The purpose of the invention is to increase the efficiency of destruction of leaf mass without grinding the coarse stems.

Поставленна цель достигаетс тем, что устройство дл обработки чайного листа, включающее неподвижный цилиндрический корпус с загрузочным бункером и установленным в нем нагнетающим шнеком с уменьшающимс шагом и увеличивающимс диаметром вала в направлении перемещени продукта, снабжено подпружиненным в осевом направлении шнеком дл одновременного скручивани и разгрузки, установленным соосно с нагнетающим шнеком, с образованием камеры сжати и скручивани листовой This goal is achieved in that the device for processing the tea leaf, comprising a stationary cylindrical body with a hopper and a delivery screw installed therein with decreasing pitch and increasing shaft diameter in the direction of product movement, is provided with an axially spring-loaded screw for simultaneous twisting and unloading installed coaxially with the injection screw, with the formation of the compression chamber and the twisting of the sheet

10 массы, причем на торцовой стороне скручиваюше-раэгрузочного Егаека выполнены дугообразные рифы.10 mass, and on the front side of the twisting-eegarek Egaek made arcuate reefs.

При этом на внутренней поверхности корпуса по его длине выполнены рифы At the same time, reefs are made on the inner surface of the hull along its length.

15 полукруглого сечени .15 semicircular section.

На фиг. 1 схематично изображено устройство дл обработки чайного листа, разрез; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 shows schematically an apparatus for treating tea leaves, a slit; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

Claims

The device includes a stationary cylindrical body 1 with a hopper 2 and an injecting screw 3 installed in it, strengthened on shaft 4 by means of bearings 5 on support 6. Screw 3 has a smart step and an increased shaft diameter in the direction of product movement, while the gap between the surface the housing 1 and the apex of the screw auger 3 remain constant. On the inner surface of the housing 1 along its length, the reefs of 7 semicircular sections are filled out. Coaxially with pumping the screw 3 on the shaft 8, a spring-loaded spring 9 auger 10 is installed for simultaneous twisting and unloading with the formation of the compression chamber 11 and the skid 4 IBANi sheet mass. On the front side of the screw 10, the grooved reefs 12 are made. The rotational speed of the screw 10 is controlled by the speed box 13 and adjusted so that the pressure in the sheet mass created afterwards in the chamber 11 is enough to crush the sheets and crush them. A nut 14 serves to move the screw 10 to the right or left. The device operates as follows. The tea leaf through the hopper 2 enters the housing .1, the winch with the screw 3 and, gradually surrendering, is moved to the chamber 11 compressed. In the chamber 11, the tea mass passes through the gaps in the support b and there, still squeezing, even on (|: it melts. When a certain size is reached, screw 10 turns on, which, by means of reef 12, twists and crushes the tea To adjust the degree of compression of the tea mass, both the volume of the chamber 11 and the speed of rotation of the screw 10 are changed, selecting their relative values. The spring 9 is designed to automatically maintain the volume of the chamber 11 and the pressure in it within the prescribed limits. The treatment of tea leaves as compared to limestone 1M allows for an increase in the yield of small fractions by 23-25% with the number of destroyed cells 95-98%, which gives an increase in the highest and first grades of tea by 10%. sheet, including a stationary cylindrical body with a hopper and installed in a non-injecting screw with a decreasing pitch and increasing shaft diameter in the direction of product movement, characterized in that aces without grinding coarse stems, it is provided subspace shnennym screw axially for simultaneous twisting and unloading mounted coaxially with blowing screw to form the compression chamber and twisting leaf mass, and on the front side of the wringing-razrruaomnogo screw reefs formed arcuate.

2. The device according to claim 1, characterized in that on the inner surface of the hull along its length there are reefs semi-circular. Sources of information taken into account in the examination 1. UK patent No. 1092479, cl. A 23 F 3/00, 1967.
