Description

Cut tobacco cooling and screening machine

Technical field:

The utility model relates to a shredded tobacco cooling and screening machine.

Background technique:

The existing shredded tobacco cooling device in the tobacco industry usually adopts a tunnel-type flow cooler. Forced cooling has a great impact on the quality of shredded tobacco, which will lead to further loss of aroma substances in tobacco. Short-term forced cooling can easily cause uneven moisture content and temperature in shredded tobacco. The bottom layer and surface layer of shredded tobacco have low moisture and low temperature, while the middle layer has high moisture and high temperature. The equipment occupies a large area, high investment, and high energy consumption.

The existing shredded tobacco screening device in the tobacco industry usually adopts a vibrating sieving machine, which is usually installed before flavoring. Screening of shredded tobacco under the condition of high flow rate, due to the frequent contact between a large amount of shredded tobacco and the screen, the shredded shredded tobacco will further increase, the thickness of shredded tobacco stacked on the vibrating sieving machine is high, the screening efficiency is low, and the shredded tobacco cannot be effectively screened point.

Invention content:

In order to overcome the defects of the prior art, the purpose of the utility model is to provide a shredded tobacco cooling and screening machine, which can sieve the shredded tobacco while performing flexible cooling on the shredded tobacco.

The utility model solves the technical problem and adopts the following technical solutions:

A shredded tobacco cooling and screening machine, in which 14-18 star rollers rotating in the same direction are arranged side by side on a frame, wherein the first star roller is directly below the feeding belt, and a shredded tobacco discharge port is arranged under the tail star roller; The first star roller to the space below the tail star roller is provided with a screening vibrating trough, and a screen is arranged in the screening vibrating trough to separate the screening vibrating trough into upper and lower layers, and the end of the lower screening vibrating trough is provided with smoke powder Outlet.

The tobacco powder outlet is located directly below the star roller adjacent to the tail star roller in spatial position.

Among the 14-18 star rollers, the gap between every two adjacent star rollers is equal, and the gap can allow the leakage of shredded shredded tobacco but cannot allow the leakage of long shredded tobacco.

Compared with the prior art, the beneficial effects of the utility model are reflected in:

The shredded tobacco cooling and screening machine of the utility model continuously rolls the shredded tobacco on the star roller, effectively cooling the shredded tobacco during the movement, and the flexible cooling can greatly improve the moisture content and temperature uniformity of the shredded tobacco after cooling, and the shredded tobacco not only has a good loose effect, The cooling effect is even.

The utility model uses the star roller to sort the shredded tobacco. The shredded tobacco passes through the gap between the star rollers and falls into the screening vibrating trough to sieve the shredded tobacco. Since a large amount of shredded tobacco stays on the star roller, the shredded tobacco on the sieve is greatly reduced. The device is installed after the shredded tobacco is dried, and the shredded tobacco still has a certain temperature during the sieving process, so the sieving efficiency is high and the crushing is small.

The shredded tobacco cooling device of the utility model also solves the problems of large occupied area, high investment and high energy consumption of existing equipment, and has the advantages of saving space and reducing energy consumption.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Symbols in the figure: 1 feeding belt, 2 star roller, 3 sieving vibrating tank, 4 sieve, 5 tobacco powder discharge port, 6 shredded tobacco discharge port.

The utility model will be further described below through specific embodiments in conjunction with the accompanying drawings.

Detailed ways:

Embodiment: In conjunction with Fig. 1, the shredded tobacco cooling and screening machine of this embodiment is provided with 14-18 star rollers 2 rotating in the same direction side by side on the frame, wherein the first star roller is directly below the feed belt 1, and the tail star roller The shredded tobacco discharge port 6 is arranged below; the space below the first star roller to the tail star roller is provided with a screening vibrating tank 3, and a screen 4 is arranged in the screening vibrating tank to separate the screening vibrating tank into upper and lower parts. Layer, the end of the screening vibrating trough of the lower layer is provided with a smoke powder outlet 5, which is located directly below the star roller adjacent to the tail star roller in terms of spatial position, that is, directly below the penultimate star roller.

In the specific setting, the driving device of the star roller adopts frequency conversion control, and the speed can be adjusted. The gap between adjacent star rollers can be adjusted according to the material condition. Larger than the size of shredded tobacco and smaller than the size of long tobacco, the screen can be selected according to the specific conditions of the screen with different apertures.

During use, the material is conveyed and dropped by the feed belt 1, and basically falls on the first and second star rollers. When the material passes through the star roller 2, most of the long shredded tobacco cannot fall through the gap between the star rollers, and continues to fall on the star rollers. 2 is transported to shredded tobacco outlet 6 and falls. At the same time, shredded shredded tobacco and a small part of long shredded tobacco fall from between the star rollers 2 onto the screen 4 of the screening vibrating trough 3, and the tobacco powder is screened out and falls into the screening vibrating trough of the lower layer, and is discharged from the tobacco powder The mouth 5 falls, and the shredded tobacco on the screen is collected from the end of the screen to the shredded tobacco discharge port 6 and falls, and enters the next processing procedure together with the long shredded tobacco.
