Drying plant (1) for particulate materials comprising: a drying duct (2) which is provided with a substantially horizontal rectilinear starting section (2a), a rectilinear ascending final section (2b) which extends upwards with a predetermined angle of inclination (±) with respect to the vertical, and a curved intermediate section (2c) which joins/ connects the rectilinear starting section (2a) to the rectilinear final section (2b); a hot gas generator (3) designed for supplying to the inlet of the rectilinear starting section (2a) of the drying duct (2) a flow (f) of process gas at high temperature; a particulate feeding device (4) which is structured so as to be able to feed/introduce into the rectilinear starting section (2a) of the drying duct (2) a flow of particulate material to be dried substantially without relevant leaks of process gas from the drying duct (2); and a bypass duct (10) which branches from the rectilinear starting section (2a) of the drying duct (2) upstream of the particulate feeding device (4), and then rejoins the drying duct (2) at the curved intermediate section (2c), so as to feed back into the drying duct (2) the process gas diverted inside it.

摘要:
A method and a device for transferring containers of shredded tobacco to individual feeders of cigarette-making machines. The device comprises a station (5) which can move preferably at right angles to the feeders (3); the station (5) is also provided with means (12a,12b) for gripping, tipping, stacking and unstacking the containers (1a,1b). The containers are arranged at supports (13a,13b) which move parallel to the feeders (3) and at right angles thereto.
摘要:
The present invention relates to a rotary conditioning drum (1) particularly usable for drying tobacco. The drum (1), which comprises heating means such as a gas or oil burner or steam heating means, has, in the latter case, longitudinal heating units which are constituted by bundles of tubes which are connected to a delivery manifold for injecting steam, and has the peculiarity of comprising at least one conveyor element (11), such as a conveyor belt (11), which is movable axially to the drum (1). The conveyor belt (11) is controlled, in its motion, by an external humidity measurement unit (13,14) and by means for controlling the thermal capacity of the drum (1). The drum (1) finally comprises, in the case of steam heating means, means for collecting and recovering the condensate at the tobacco feed side (9). The presence of the movable conveyor belt (11) allows, if the humidity of the tobacco in output deviates from the desired value, to axially move the belt (11) inside the drum (1) to the point at which the tobacco is at the required humidity. It is thus possible to obtain, in an extremely effective manner, a variation in the "useful" length of the drum (1) with a consequent extremely rapid and precise response during transient periods.

The present invention refers to an apparatus (1000) for making a sheet of material comprising vegetable and/or alkaloid substances. The apparatus (1000) includes a roller rolling mill system (100) comprising a plurality of rollers (104a, 104b, 104c, 104d) rotatable around respective rotation axes (Ra, Rb, Rc, Rd) defining a rolling mill path (LP) provided with pressure lines (Nf, Ni, Ne) adapted to substantially press the material so as to provide the latter with a sheet-like shape, and a scraping system (200) configured to engage by contact the working surface (106d) of a transfer roller (104d) along a contact line (Cd) so as to detach said material. Specifically, the scraping system (200) comprises a closed-loop endless scraping band (202) movable at said contact line (Cd) parallel to the rotation axis (Rd) of the transfer roller (104d) by means of an actuating assembly (206).
摘要:
An apparatus is provided for breaking down cigarettes to separate the filter portion from the tobacco portion. The apparatus includes a conveying duct (2) that conveys cigarettes in an orientation such that the longitudinal axes of the cigarettes and the conveying duct are substantially in alignment; cigarette - accommodating means (11) comprising at least one channel, the channel being configured to accommodate a cigarette, such that the longitudinal axes of the cigarette and the channel are substantially in alignment; and means for lining up the channel with the conveying duct, to allow a cigarette to be delivered from the conveying duct to the channel. The apparatus further includes a stopping surface (14) adjacent to the cigarette - accommodating means, the stopping surface being arranged to support a cigarette such that the cigarette remains partly accommodated within the channel. The stopping surface (14) is positioned such that when the cigarette is partly accommodated within the channel and supported against the stopping surface, the filter portion of the cigarette protrudes from the cigarette - accommodating means. The apparatus further includes separation means (21) for separating the protruding filter portion from the tobacco portion.
摘要:
A tobacco cooling device (7), particularly for a tobacco drying system comprising means for the circulation of a process gas at high temperature in a circuit provided with a tobacco drying column and with a device for separating the process gas from the tobacco. The device is adapted to utilize the enthalpy content of the tobacco available downstream of the discharge point of the separation device.
