The invention relates to tea fermentation devices and can be used in tea factories of primary processing.

The aim of the invention is to reduce the metal consumption of the device, as well as the implementation of the fermentation process with a large layer of tea leaf,

Figure 1 shows the principal installation scheme for tea fermentation; 2 and 3 - distribution conveyor, respectively v); on the side and on the top, in FIG. 4 and 5 - baking powder layer sheet, respectively, a side view and top.

I The fermentation unit includes an inclined loading conveyor 1, a metal chamber 2, a distribution conveyor 3 located under the discharge part of the loading conveyor 1, the distribution conveyor being located perpendicular to conveyors 4 and 5 inside the metal chamber 2, conveyors 4 and 5 are arranged one above the other in a horizontal plane and are provided with inclined side boards 6 and individual actuators and mechanisms for switching. : - growths (not shown), cleaning devices 7 installed under the discharge part of the conveyors 1,4 and 5, sheet layer baking powder 8 installed above the discharge part of the second conveyor 5, collector with outlets 9 located under the distribution conveyor 3 and in front baking powder 8 tea leaves, connected to the conditioner 10, discharge conveyor 11, located under the discharge part of the conveyor 5 across it.

The distribution conveyor 3 (Figures 2 and 3) includes elements for moving in the form of pins 12, pivotally mounted on a chain 13 Gal l, mounted on guides 14 and located above the pallet 15, which in turn is located between the drums the upper branches of the conveyor, having a slot in the form of a rectangular triangle 1b for gradual spilling of tea as measure. displacement of the mass and its distribution

The baking powder sheet 8 (figure 4 and 5) includes a pair of rollers 17 installed with the rotor

opposite each other, with loosening blades 18 fixed on their surface, located in the schmmat pore e1. An umbrella 19 is arranged on the upper part of chamber 2 for exhausting conditioned air.

The installation works as follows.

The twisted and crushed mass of tea intended for fermentation, using an inclined loading conveyor 1, is fed to the loading part of the distribution conveyor 3, captured by pins 12 and moved on a stationary tray 15, where as the weight of the tea moves, it gradually graduates through the slot 16 and is even the distribution on the loading part of the first conveyor 4. At the same time, as the tea is pushed through the slot, the weight of the sheet is blown and pressed by conditioned air from the collector with outlets 9. During the movement of a certain layer on the conveyor 4, the inclined beads prevent the shredding sheet from spilling on the side edges of the conveyor. In order to increase the working surface of the conveyors 4 and 5, their working body is made of food rubber, the inclined side walls 6 of the conveyors 4 and 5 are also made of food rubber or organic glass.

From the conveyor 4, the tea mass is supplied to the baking powder of the 8 layer of sheet, where it passes between slowly rotating blades 18, loosens, and simultaneously when the tea leaves fall from top to bottom, it is blown with conditioned air from the collector with outlets 9. After passing through the conveyor 5, the weight falls on the discharge conveyor 11 and then to the next process. The bottom surface of each conveyor 4 and 5 and the discharge conveyor 11 is cleaned of stuck tea leaves with the help of cleaning devices 7. The used conditioned air is discharged from the chamber 2 through an umbrella 19.

The speed of the conveyors 4 and 5 is controlled by individual drives and speed switching mechanisms, thereby controlling the duration of the fermentation process, and more time is needed for fermentation and the thickness of the sheet in order to match the raw material after the twisting process. optimal limits. In addition, using individual drives and gearshift mechanisms to ensure forced interruptions in the following technological processes, klch, on the contrary, if the second conveyor of the installation needs to be unloaded depending on the degree of softness of the raw material and the degree of its fermentation.

The production program of the conveyors can be equal or different, so that depending on the need, the duration of the process is reduced or increased with a corresponding change in the sheet layer.

Claims (1)

A tea fermentation plant allows for an even distribution of the fermentable mass of the leaf to Q e. to achieve different speeds on the conveyor's entire surface with poelers as needed, for example, when standing loosening and crushing with conditioned air, to adjust the process duration in accordance with the production program and productivity, to achieve complete mechanization of the fermentation process and ensure continuous production, reduce metal consumption by using a smaller, 20 claims for the number of conveyors with the same performance, which is achieved by increasing the layer tea leaves, to comply with the sanitary conditions of labor, to reduce labor costs per unit of production by 100%, to increase the weighted average score of products by 0.25 points due to the process in the regulation mode. During hot periods of the season, oxidative-enzymatic processes from the beginning of the twisting process occur more intensively. After completion of the twisting process for such, the raw materials require less fermentation time and thickness of the sheet. In this case, the conveyor speed25 thirty 35 A plant for the fermentation of tea, including loading and unloading conveyors, a system for supplying conditioned air to a chamber with horizontal conveyors placed one above another with inclined lateral sides, devices for cleaning each conveyor, and a baking powder for ca. It is based on the fact that, for the purpose of noi bmie-ing, the quality and quality of the final product, it is equipped with a metering distribution conveyor installed in the entrance section of the chamber in which two horizontal conveyors are placed a, the conditioned air supply system is made in the form of a collector with outlets, the outlets of which are located respectively under the distribution conveyor and under the baking powder of the tea leaf, while the latter is located on the inlet section of the lower horizontal conveyor. The ditch increases and, accordingly, the thickness of the sheet layer on the conveyors decreases, which ensures the oxidation of the composite substances of the sheet within acceptable limits. During cold periods of the season, oxidative-enzymatic processes develop slowly from the beginning of twisting, for such a raw material after completion of the twisting process requires more fermentation time and the thickness of the sheet layer, which ensures the oxidation of the composite substances of the sheet within optimal limits. In addition, individual drives and gearshift mechanisms are provided. the achievement of different speeds of the conveyors as needed, for example, with the invention formula on the occurrence of forced interruptions in the following technological processes, klch, on the contrary, when the need arises for unloading the second conveyor of the installation, depending on the degree of tenderness of the raw materials and the degree of its fermentation. is. the achievement of different speeds of the conveyors as needed, for example, with the invention formula Q is. achieving different speeds of conveyors as needed, for example, at 5-20 five 0 five 0 A plant for the fermentation of tea, including loading and unloading conveyors, a system for supplying conditioned air to a chamber with horizontal conveyors placed one above another with inclined lateral sides, devices for cleaning each conveyor, and a baking powder for ca. It is necessary to ensure that, in order to noi bmie-ni the productivity and quality of the final product, it is equipped with a metering distribution conveyor installed on the inlet section of the chamber in which two horizontal conveyors are placed a, the conditioned air supply system is made in the form of a collector with outlets, the outlets of which are located respectively under the distribution conveyor and under the baking powder of the tea leaf, while the latter is located on the inlet section of the lower horizontal conveyor. eight Order 5291/2 Circulation 525 VNIIPI State Committee for Inventions and Discoveries at the State Committee on Science and Technology of the USSR 113035, Moscow, Zh-35, Raushsk nab., A / 5 Fig.Z Subscription
