摘要:
Procédé et appareil de lyophilisation de produits aqueux sensibles à a chaleur sur une base continue, utilisant des tamis moléculaires destinés à séquestrer la vapeur d'eau de sublimation. Au moins deux lits de tamis (45) sont utilisés séquentiellement, l'un des lits étant régénéré à la chaleur alors que l'autre est un adsorbant actif de vapeurs condensables. La production de chaleur est regulée durant la lyophilisation et la régénération des lits peut être effectuée sans l'utilisation d'un gaz de purge. Des avantages de certains types et de certaines grandeurs de tamis moléculaires, dans un procédé de lyophilisation continue, sont discutés.
摘要:
A method of controlling temperature inside a chamber according to a temperature profile which includes a plurality of segments, each of which has an increasing or decreasing temperature period and a subsequent constant temperature period. An operator only needs to inputting a target temperature, a first period, and a second period, one time each, as parameters, for each sub-input-state which is part of an input-state and which is provided for each segment, so that the temperature is varied to match the target temperature for the first period and that the target temperature is maintained for the second period, for each segment.
摘要:
A method and apparatus for freeze drying heat sensitive aqueous products on a continuous basis, utilizing molecular sieves to sequester the sublimating water vapor. At least two beds of sieve (45) are used sequentially, one being heat regenerated while another is actively adsorbing condensable vapors. Exotherm is controlled during freeze drying, and bed regeneration may be accomplished without the use of a purge gas. The advantages of certain types and sizes of molecular sieves, in a continuous freeze drying procedure, is discussed.

A pressure molding apparatus comprises a furnace (4) defining a heating space (6) for accommodating a mold assembly (28) including a mold body (30) charged with a raw material (40) to be molded, and a pressure piston (32) for pressurizing the raw material; heating means (22) for heating the heating space; and load imposing means (54) for imposing a load on the pressure piston to mold the raw material. The load imposing means (54) includes at least one weight means (56) and weight supporting means (58). The weight supporting means (58) is selectively set in a load-free state in which the weight supporting means (58) supports the weight means so that the weight of the weight means is not imposed on the pressure piston, and a load imposed state in which the weight supporting means releases the support of the weight means so that the weight of the weight means is imposed on the pressure piston.

A thermostatic apparatus (1) and a temperature distribution improvement method of the thermostatic apparatus (1) include: an outer tank (11); an inner tank (13) provided inside the outer tank and having an outer peripheral surface forming a jacket structure together with the outer tank (11); a separator (31, 33) arranged inside the outer tank (11) and separating the jacket structure into a plurality of chambers (20L, 20R); and a thermostatic unit (35L, 35R) configured to supply temperature-controlled thermostatic medium (L, R) to each of the plurality of chambers (20L, 20R) separated by the separator (31, 33).
摘要:
A sample treatment system includes a robot that includes a main body with a plurality of arms and a plurality of hand tools to be detachably attached to the plurality of arms, and a treatment instrument for treating a sample is disposed within the reach of the hand tools attached to the plurality of arms. The robot selects and puts on suitable hand tools according to a treatment to be performed on a sample to treat the sample.
摘要:
There is provided a continuous flow type homogenizer. The homogenizer comprises, a tubular container (7) having at upper end thereof an inlet (7c) for introducing tissue to be homogenized and at lower end thereof an outlet (7d) for discharging the homogenized tissue, a pestle (3) disposed freely rotatable in the tubular container with a clearance defined between the inner surface of the tubular container and the peripheral surface of the pestle, a rotation shaft driving means (13) connected to a rotation shaft (11a) of the pestle, a speed setting means for setting the rotation speed of the pestle, and a speed controlling means for controlling the speed of the rotation shaft with a predetermined speed gradient with respect to a speed value set by the speed setting means.
