UNLOADING-LOADING DEVICE FOR HORIZONTAL FREEZING CHAMBERS AND A FREEZING DEVICE WITH UNLOADING-LOADING DEVICE FOR HORIZONTAL FREEZING CHAMBERS Russian patent published in 2020 - IPC F25D31/00 B65G47/82 

FIELD: machine building.

SUBSTANCE: group of inventions relates to unloading-loading equipment of freezing chambers. Device comprises linear chain drives, movable rod rigidly fixed near first end or first end of first chain drive, as well as rigidly fixed near first end or at first end of second chain drive, and feeding device for retraction and extension of chain drives. Freezer comprises one or more horizontal freezing chambers, as well as one or more unloading and loading devices for horizontal freezing chambers, two or more transportation means in form of at least one input conveyor and at least one outlet conveyor adjacent to horizontal freezing chamber, freezing chamber area, containing stack of freezing plates. First chain drive is engaged with the first sprocket, and the second chain drive - with the second sprocket. Axes of rotation of the first and second sprockets are parallel to axis Z, so that during movement of chain drives from retracted position to extended and from extended position into retractable movable rod is located in plane XY, and longitudinal direction of movable rod is parallel to axis X.

EFFECT: prevented deterioration of chain drives.
