The conveying system includes a conveying chamber in which the conveying path is arranged. At least one component of a conveying mechanism for conveying the material to be conveyed is arranged outside the conveying chamber. The conveying mechanism includes a traction drive having at least one traction element by means of which carrying elements can be moved in order to convey the material to be conveyed. The carrying elements are arranged in the conveying chamber and protrude through a through-opening out of the conveying chamber. Inside the conveying chamber and/or in the region of the through-opening, the surfaces of the carrying elements are at least partially provided with a thermal insulation material. ## Claims ### Claim 1 A conveying installation for conveying a material along a conveying path, comprising: a conveying chamber through which the conveying path passes; and at least one component of a conveying mechanism for conveying the material arranged at least outside the conveying chamber; wherein the conveying mechanism has a traction mechanism drive with at least one traction mechanism by which carrier elements are movable in order to convey the material; wherein the carrier elements are arranged in the conveying chamber and protrude out of the conveying chamber through at least one passage opening; wherein at least parts of the conveying installation at least within at least one of the conveying chamber and in a region of the passage opening are at least partially provided with a thermal insulation material; wherein at least one of: surfaces of the carrier elements at least within at least one of the conveying chamber and in the region of the passage opening are at least partially provided with a thermal insulation material, and at least one container for receiving the material for conveying is arranged on at least one of the carrier elements; wherein at least one of a surface and an inner surface of the container is at least partially provided with a thermal insulation material; wherein a secondary chamber is provided which is connected to the conveying chamber by the at least one passage opening; and wherein the carrier elements protrude through the at least one passage opening into the secondary chamber and the at least one traction mechanism is arranged in the secondary chamber. ### Claim 2 (depends on 1) The conveying installation as claimed in claim 1, wherein a separating surface between a surface of the conveying chamber within the conveying chamber and at least one adjacent outer surface of the conveying chamber is at least partially provided with the thermal insulation material. ### Claim 3 (depends on 1) The conveying installation as claimed in claim 1, wherein the surfaces of the conveying chamber are at least partially provided with the thermal insulation material toward an environment. ### Claim 4 (depends on 1) The conveying installation as claimed in claim 1, wherein surfaces of the carrier elements outside the conveying chamber are not provided with a thermal insulation material. ### Claim 5 (depends on 1) The conveying installation as claimed in claim 1, wherein surfaces of the carrier elements outside the conveying chamber are at least partially provided with a thermal insulation material. ### Claim 6 (depends on 1) The conveying installation as claimed in claim 1, wherein the secondary chamber has a fluid atmosphere differing at least one of physically and chemically from a fluid atmosphere in the conveying chamber. ### Claim 7 (depends on 1) The conveying installation as claimed in claim 1, wherein at least one of the conveying chamber and the secondary chamber are part of an installation housing and the installation housing has at least one fluid inlet and at least one fluid outlet and, apart from the at least one fluid inlet and the at least one fluid outlet, is designed to be fluid-tight or approximately fluid-tight. ### Claim 8 (depends on 1) The conveying installation as claimed in claim 1, wherein the carrier elements at least partially separate the conveying chamber from the secondary chamber, in which the at least one traction mechanism is arranged. ### Claim 9 (depends on 1) The conveying installation as claimed in claim 1, further comprising one of a fluid infeed and a fluid circuit system, the one of the fluid infeed and the fluid circuit system comprising the secondary chamber configured for conducting a fluid through the at least one passage opening between the secondary chamber and the conveying chamber. ### Claim 10 (depends on 1) The conveying installation as claimed in claim 1, wherein a fluid circuit system is not provided. ### Claim 11 (depends on 1) The conveying installation as claimed in claim 1, wherein surfaces of the carrier elements are at least partially provided with the thermal insulation material on their top side and their bottom side. ### Claim 12 (depends on 1) The conveying installation as claimed in claim 1, wherein surfaces of the secondary chamber are connected to the conveying chamber via thermally insulated surfaces. ### Claim 13 (depends on 12) The conveying installation as claimed in claim 12, wherein the thermally insulated surfaces limit a heat input into an atmosphere of the secondary chamber.
