Abstract: A moistening method for tobacco stems comprises 1) preparing a hydrated humectant for tobacco stem, 2) placing cut tobacco stems in the hydrated humectant to form impregnated cut tobacco stems; 3) taking out and drying the impregnated cut tobacco stems; the hydrated humectant for tobacco stem is a saline aqueous solution of AnB, the AnB is NaH2PO4, potassium gluconate or oxalic acid, and each one of the AnB has a weight-percent concentration of 0.05 wt % to 5 wt %.

Abstract: A full-automatic dynamic tobacco moisture analysis climate chamber comprises an enclosed constant-temperature constant-humidity cabin, which is communicated with an air temperature and humidity processor to form an air circulation loop; a weighing platform is disposed inside the constant-temperature constant-humidity cabin, a sample delivery hanger is hung inside the constant-temperature constant-humidity cabin, at least one placement carrier is disposed below the sample delivery hanger, a sample vessel is placed on the placement carrier, the sample delivery hanger is further connected to a drive mechanism outside the constant-temperature constant-humidity cabin and the drive mechanism drives the sample delivery hanger to perform operations, to place the sample vessel on the weighing platform for weighing.

Abstract: The present invention relates to the field of tobacco, and more particularly to a use of a saline aqueous solution as a hydrated humectant for tobacco stem. The present invention provides a use of a saline aqueous solution as a hydrated humectant for tobacco stem, and the saline aqueous solution is an aqueous solution of AnB, wherein the cation A is selected from one of potassium, sodium, ammonium, and hydrogen, the anion B is selected from one of hydrogen phosphate, dihydrogen phosphate, oxalate, lactate, citrate, malate, gluconate, and acetate, and n is a positive integer. The hydrated humectants in the present invention has the effect of taking part in a substitution reaction with calcium pectate inside the tobacco stems to generate a hydrated calcium salt, thereby preventing escape of water molecules, reducing evaporation and dissipation of moisture, and achieving a desirable moistening efficacy.
