<p>PURPOSE:To enable safe freezing processing of fruits, etc., in a germ-free state, by blending nitrogen gas in a freezing chamber with pressurized air from an air compressor, filtering and sterilizing the blend gas, introducing the gas into a germ-free chamber and keeping the gas under a higher pressure than atmospheric pressure. CONSTITUTION:This device is provided with a germ-free chamber body 11 formed into a tunnel shape, work gloves 36 attached to openings formed on both sides of the germ-free chamber body 11, a partition wall 30 formed at the inlet of the germ-free chamber and a circulation flowing water passage (C) of disinfecting.washing water for transferring disinfected washed agricultural and marine products.fruits from the outside of the germ-free chamber under the partition wall 30 into a germ-free chamber (B). A freezing chamber (D) by liquid nitrogen is connected to the outlet of the germ-free chamber and the nitrogen gas in the freezing chamber (D) is blended with pressurized air by an air compressor 27, filtered.sterilized and then introduced into the germ- free chamber (B) to keep the germ-free chamber (B) under a higher pressure than atmospheric pressure. As a result, fruits, marine products, etc., can be safely frozen and processed in a germ-free state.</p> |
