The drawbacks of the device are that the operation of the drying device with a rotating drum, in which a vacuum is created, can be carried out only periodically, and its loading and unloading. are inconvenient and difficult. The field of use of such devices is rather limited, since they are intended only for processing easily bulk, non-sticky lump materials. The material may adhere to the inner surface of the cylinder, thereby creating a layer that prevents heat transfer, and for this reason the coefficient of thermal use of such a device is relatively unacceptable. The rotation of the drum loaded with lumpy dried material requires relatively high energy consumption. The aim of the invention is to increase the reliability of the device. This goal is achieved by the fact that in a device for heat treatment of materials, comprising a hollow body with a jacket, mounted horizontally for rotation, tools for unloading and unloading material, metering devices, a system for supplying and discharging a thermal agent, the hollow body consists of two parts, one of which is an expanding drum, the smaller end of which is provided with an opening on the axis for feeding material into the housing, and the larger one is provided with an eccentric located opening It connects the cavity of the drum with the second part of the body, made in the form of a zigzag tube, and the fact that the expanding drum is a truncated pyramid:,. (truncated cone), and a zigzag-shaped tube in cross section has a polygon (circle). The shirt can be made of separate interconnected pipelines of parts covering the side surfaces of the drum and each of the straight sections of the zigzag tube, or the jacket is a cylindrical vessel for the thermoagent, inside which the housing is located, and the system for feeding and draining the thermoagent contains means for feeding the thermal agent into the housing from the outlet side of the product from the housing; and means for withdrawing the thermal agent from the entry side of the material into the housing. Inside the drum are placed stirring agitators. Dosing devices are located at the places of loading and unloading of material, the loading device being equipped with a feeding screw located between the dosing device and the drum. Figure 1 shows the device, vertical incision along the geometric longitudinal axis; in FIG. 2 is a section A-A in FIG. on fig.Z - section bb on figl; in fig. 4 - section bb In figure 1; in fig. 5 is a variant of the device, whose areas due to complete isolation from each other can be in different conditions by supplying a heating or cooling medium and creating a vacuum, a vertical section; in fig. 6 is the same, and the device can be heated and / or cooled both from the inside and from the outside in FIG. .7 - the same, and the devices are equipped with a container with a pulsator containing a cooling medium; on phi 8 - the same, and the device contains a closed container with steam and operates under vacuum; in fig. 9-13, combinations of cross sections of the drum and the zigzag tube are possible.
