This pig carcass treatment unit is such that a trolley ensured to prevent carcasses from mutual contact and a carcass treatment chamber equipped with at least a downroll-type automatic skinning machine and an automatic halving machine are unitized and the succeeding treatment chambers are also unitized, where appropriate, so as to be collocatable. 屠体同士の接触を防止するトロリーと、少なくともダウンロール式自動皮剥ぎ機と自動背割り洗浄部を備えた屠体処理室をユニット化し、以降の処理室をも必要に応じて、併設可能にユニット化する。 - 特許庁
