摘要:
An expanding apparatus supplies an expanding agent to an impregnating vessel, and continuously supplies and discharges a material, e.g., a tobacco material to and from the impregnating vessel through a valve while pressure-increasing or pressure-decreasing the material, thereby continuously expanding the material. The expanding agent supplied to the impregnating vessel, the valve, and the like is recovered and, air, an impurity gas, or the like mixed in it is removed. Thereafter the expanding agent is pressure-increased to a high pressure and supplied to the impregnating vessel and the valve again.
摘要:
An expanding apparatus continuously expands a material, e.g., a tobacco material and supplies gaseous carbon dioxide as an expanding agent to an impregnating vessel by an expanding agent supply to maintain a predetermined impregnating pressure. The material is continuously supplied to the impregnating vessel by a material supply while increasing the pressure of the material. The material is continuously discharged from the impregnating vessel by a material discharge while decreasing the pressure of the material. The expanding agent supply has a heat exchanger to perform heat exchange between carbon dioxide to be supplied to the impregnating vessel and a coolant, thereby cooling carbon dioxide. The state of carbon dioxide to be supplied to the impregnating vessel is controlled in accordance with the temperature or the like of the tobacco material discharged from the impregnating vessel, so that carbon dioxide is effectively impregnated and no dry ice is formed in the material discharge or the like.

An expanding apparatus of this invention includes a preparatory vessel that is supplied with material of agricultural origin, for example, tobacco material. The tobacco material in the preparatory vessel is supplied to an impregnation vessel through a convey pipe. Carbon dioxide having an impregnation pressure is supplied to the impregnation vessel so as to fill the same. A booster mechanism is associated with the convey pipe to increase the pressure of carbon dioxide around the tobacco material to a pressure substantially equal to the impregnation pressure in the impregnation vessel when the tobacco material is supplied from the preparatory vessel to the impregnation vessel. The tobacco material impregnated in the impregnation vessel is discharged to a blow pipe through a delivery pipe and is expanded by means of a heating medium generated in the blow pipe. A debooster mechanism is associated with the delivery pipe to reduce the pressure of carbon dioxide around the tobacco material to a pressure substantially equal to the pressure in the blow pipe when the impregnated material is discharged from the impregnation vessel to the blow pipe.
摘要:
An oral tobacco product which includes a tobacco pouch obtained by wrapping tobacco particles made from a tobacco material in a wrapper, the tobacco pouch allowing a user to take in tobacco components of the tobacco particles via saliva, when put in the user's mouth, and an outer wrapper individually wrapping the tobacco pouch therein. The outer wrapper has liquid impermeability and is provided with a lug for the user.

A stator of a dynamo-electric machine includes core pieces obtained by laminating iron plates divided in a circumferential direction per pole-tooth unit and having projecting and recessed engaging parts at their dividing faces, and then welding the iron plates by laser at their inner and outer peripheries. A winding part is formed around each pole-tooth unit of the core pieces. A predetermined number of the core pieces are bonded into the loop, with the projecting and recessed engaging parts engaged with each other and rigidly welded at outer peripheries of bonding faces by laser in a laminating direction.
