Cold-storage incubators that are easy to disassemble and assemble may become the development trend of the future. An experiment on the effect of cold-chain transportation was performed on an assemble-able cold-storage incubator with pleurotus ostreatus (oyster mushrooms). During the experiment

the temperatures of the air

the center of the pleurotus ostreatus

and the cold-storage agent in the incubator were tested; then

the heat-leakage rate from the gaps in the cold-storage incubator assembly was determined. Meanwhile

the pleurotus ostreatus were sampled every 30 hours to make a sensory evaluation and the nutritional indicators were tested to judge the effect of the cold-chain transportation. The results show that

in an ambient temperature of 25 ℃

it takes 56 hours for the coolant to completely liquefy

which is eight hours less than that estimated. This means that the required coolant amount

which can be adjusted by a factor-correction method

was actually larger than the estimation. Moreover

the heat-leakage rate from the gap increased to 12.97%

which was thought to be a bit larger proportion. Thus

it is necessary to improve the assembly process of the assemble-able cold-storage incubator. In addition

the commodity and nutritional value of pleurotus ostreatus are rarely reduced during cold storage. When the values after 60 h were compared with those at the beginning

the sensory evaluation scores

the soluble-solids content

the soluble-protein content and the vitamin C content had dropped by 3.53%

5.9%

4.2% and 9.96% respectively.
