Description

one

The invention relates to the food industry and can be used in primary factories for drying different types of tea.

The purpose of the invention is to improve the quality of tea by eliminating its abrasion.

FIG. 1 shows a schematic diagram of a device for drying tea, a general view; in fig. 2-section A-A in FIG. t.

The device consists of a body 1, a vertical conveyor 2 consisting of drums 3 and 4, a metal mesh 5 and blades 6. On the side of the working branch of the conveyor 2, the wall 7 of the body is perforated and has a nozzle 8 for air supply, divided by a vertical partition 9 into two sections 10 and 11. The opposite wall of the case is made in the form of a vertical rectangular section 12, divided into HecKaibKo, for example, six sections; 1, 13–18 partitions 19. At the bottom, the duct has an opening 20 for loading tea, Under the lower end of the conveyor 2 and communicating with the pipe 21. A conveyor 22 with a perforated clamp 23 is installed above the conveyor 2. A horizontal screw 24 is located in its lower part, the coils of which are widened in steps decreasing from the loading nozzle 25 to the unloading nozzle 26. In the side walls 27 of the housing 1 there are nozzles 28 and 29 for exhaust air. The conveyor is driven by an asterisk 30.

The device for drying tea works as follows.

The electric drive (not shown) of the conveyor 2 is turned on and air is simultaneously supplied to both sections 10 and 11 of the nozzle 8 and to all sections 13-18 of the air duct 12 and raw tea is fed from the nozzle 25. At the same time, the product moves with a horizontal screw 24 and spills to the edge conveyor 2, is caught by the blades 6 and gradually goes down along the perforated wall 7, where it is poured into the hole 20 of section 13 of the duct 12, is caught by the air moving inside this section, and rises into the vessel 22. Here the air loses speed and is removed to atm. osferu through a perforated krshku 23, and the tea is lowered down onto a rotating auger 24, through which is advanced toward the tube 26 by a certain length and again prosypaets down on the conveyor 2,

Next, tea gradually passes through all sections 14-18 of duct 12 in a similar manner, is dried and discharged from the device, the drying air enters from pipe B, enters the tea layer through the perforated wall 7, and is discharged into the atmosphere using pipes 28 and 29. In section 13-18 duct 12 through the pipe 21 is cooled air.

In the proposed device, a favorable condition is created to maintain an optimal drying mode as the material dries, this is facilitated by the possibility of intensive mixing of the product when it rises through pneumatic tubes and the ability to supply air with different optimal parameters in each vertical section.
