    摘要: A liquid nitrogen quick-freezing preservation method for fresh bamboo shoots. The method includes performing a coating treatment on cuts of fresh bamboo shoots, which reduces the moisture loss through the cuts, slows down the degree of lignification of the bamboo shoots, mitigates color changes at the cuts, inhibits excessively fast reproduction of microorganisms at the cuts and prevents invasion of microorganisms from the cuts, so that a decrease in nutritional value is reduced, the deterioration of the appearance quality of the bamboo shoots is mitigated, and the nutritional value and commodity value of the bamboo shoots are maintained. The method further includes an intermittent ultrasonic treatment on the fresh bamboo shoots, so that coating substances form films on the surfaces of the cuts more easily, preventing the fresh bamboo shoots from being eroded by microorganisms and preventing nutrient substances from being decomposed and utilized by the microorganisms.

    摘要: An air composition adjusting device includes: a carbon dioxide separator that separates carbon dioxide from air-to-be-treated to be supplied to a target space; a gas supply path including a high concentration gas supply path through which the carbon dioxide separator communicates with the target space; and a controller that performs a carbon dioxide concentration raising operation of supplying a high carbon dioxide concentration gas, which has a higher carbon dioxide concentration than air-to-be-treated before being treated, to the target space through the high concentration gas supply path.

    摘要: The present invention addresses the problem of providing a novel freezing system and a method for producing frozen ingredients, the system and method being such that the amount of free water after defrosting of the frozen ingredients is lower than with conventional freezing. The present invention solves the above problem by providing an ingredient freezing system comprising two or more freezing units for freezing the ingredient, and a transport unit for transporting the ingredient to the two or more freezing units, the two or more freezing units being configured so as to freeze the ingredient in stages so that the ingredient is frozen at progressively lower temperatures as the ingredient is transported on the transport unit.

    摘要: A carbon dioxide sensor (92) measures the carbon dioxide concentration of inside air. An inside air control system (30) controls the carbon dioxide concentration of the inside air based on a measured value obtained by the carbon dioxide sensor (92). If the measured value obtained by the carbon dioxide sensor (92) returns to a predetermined normal range after falling outside the normal range, the controller (110) of the inside air control system (30) performs a determination operation. The determination operation is an operation for supplying outdoor air to the carbon dioxide sensor (92) to determine whether or not the carbon dioxide sensor (92) is normal.
