Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a drying chamber in which a transport carrier to which a substance to be dried is adhered is filled and dried while being lowered, a mechanism for separating the dried substance from the transport carrier, and a mechanism for separating the dry substance from the transport carrier. The present invention relates to a drying apparatus that is provided with a nuclear transport device for transporting the carrier to supply it to the drying chamber, and a transport mechanism that transports the transport carrier to the tin transport device while sliding it on the bottom of the drying chamber.

In the above-mentioned drying apparatus, the transport carrier supporting the dry substance takes a path in which it slides into contact with the bottom surface of the drying chamber while being transferred from the drying chamber to the separation mechanism, and the material is carried by sliding contact with the bottom surface of the drying chamber. A situation occurs in which some of the dried substances separated, and the accumulation of dried substances on the bottom of the drying chamber obstructs the smooth transfer of the carrier, leading to malfunction of the entire device and a decrease in the recovery rate of dry substances. It was something that caused

In addition, the dry substances deposited on the bottom surface of the drying chamber and the dry substances pressed against the conveyance carrier are subjected to pressure by the conveyance carrier accumulated and filled in the drying chamber, so that the dry substances, for example, waste sugar Fermented liquid made from secret liquid,
In addition, if the liquid contains thermoplastic substances, such as waste liquid from fermentation and distillation of alcohol from waste sugar concentrate, it will melt under pressure, and the liquid will melt at the bottom or near the top of the drying chamber. There have been cases where not only the conveyance mechanism itself but the entire drying apparatus becomes inoperable due to body blocking.

The present invention has been made in view of the above-mentioned circumstances, and in the above-mentioned drying device, the bottom surface of the drying chamber is formed of a net-like body, so that the conveying mechanism and the net-like body cooperate with each other. The dry substance separated from the conveying light body is taken out through the net-like body into a collection space below, and cooling air is supplied to the net-like body from the collection space side. characterized by something. That is, by utilizing the separation phenomenon of the dry substance due to the sliding contact of the carrier against the bottom surface of the drying chamber, the dry substance is actively separated at this location, and
The separated dry substance is taken out through the bottom of the drying chamber to the collection space below to prevent it from accumulating on the bottom of the drying chamber.
It is possible to avoid accumulation of dry substances during the transport path of the transport carrier, and to improve the recovery rate of dry substances by performing separation processing in advance before the separation mechanism. Although the transition to the blocking phenomenon can be prevented by avoiding the accumulation of dry substances, the bottom surface of the drying chamber is further cooled.
It is expected that the blocking phenomenon will be suppressed to a higher degree, and a drying apparatus that can maintain smooth operation of the apparatus over a long period of time as a whole and has a high drying material recovery rate has been provided.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.
