Horizontal plate freezer for freezing articles inside said horizontal freezer during a freezing process comprising: - a plurality of freezer plates forming a stack of freezer plates, where said plurality of freezer plates are arranged substantially horizontal, defining a distance between the freezer plates, where in use articles to be frozen are arranged on one or more freezer plates, - where said stack of freezer plates are arranged between a top frame and a bottom frame, where said top frame is arranged at a horizontal level above the stack of freezer plates, and said bottom frame is arranged at a horizontal level underneath the stack of freezer plates, - at least one intervention unit with at least one engaging device, - at least one displacement device comprising a first end positioned above a topmost freezer plate and a second end connected to said bottom frame, where said bottom frame is moveably connected to the top frame by the at least one displacement device capable of lifting and lowering the bottom frame to a predefined position, where one or more freezer plates rests on the bottom frame, where said engaging device can engage individual freezer plates of said plurality of freezer plates, and displace said engaged freezer plate thereby providing an increased distance between two adjacent freezer plates, and maintain the increased distance during loading and/or unloading of articles to or from said freezer plates, and characterized in that: the engaging device is arranged moveable in a longitudinal direction along said intervention unit(s), whereby the engaging device is lifted and lowered along said stack of freezer plates, where said intervention unit comprises a threaded spindle, where said engaging device is arranged moveably in a longitudinal direction along said threaded spindle, where the intervention unit can hold the engaging device in a predefined elevated position. -
