Application filed October 2, 1920. Serial No. 414,258.

To all whom it may concern:

Be it known that I, JACOB DINER, citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain newand useful Improvements in Sterilizing Procquality of the article itself or damaging the container or package holding same.

An additional object-is to provide a process of the character described and for the purpose set forth, which will be expeditious in its application and economical in its cost of operation. f

How these Iobjects are attained will beset forth in the following description taken in conjunction with the accompanying 'drawin ,in which;

igure 1, is a longitudinal section of an apparatus employed in the application ofy the process, and

,Figl 2, is a transverse section of same, taken along the line 2-2, and looking in the direction indicated. m

Referring in detail to the apparatus employed in the process, 10 designates a heating or sterilizing compartment, preferably circular in cross-section and formed with an outer jacket 11, and provided with a closing member 12, which is so constructed and arranged, that when in closed position, it will hermetically vseal the compartment. The

outer wall may be covered with vany suitable n heat resisting material 13, preferably asbestos composition.

The jacket 11, is provided with a conducting pipe 14, by means of which, steam or other expansible heating fluid is allowed to enter the jacket and an outlet or return conductor 15, may be provideddto permit the circulation of the expansible heating duid between the sterilizing apparatus and rthe source of fluld supplyn Suitable thermometers, pressure gages, pet cocksand a blow- `off valve are provided and arranged to communicate with the jacket and the sterilizing compartment. A portable cage, basket or conveyance 16, may be provided to carry the products to be sterilized, and a pan or trough 17, may also be arranged at the bottom of the compartment for the purpose hereinafter set forth.

1n the application of this invention, the apparatus is employed as follows;

The packaged tobacco products to be sterilized are placed within the compartment 10, preferably held within any suitable con- Veyance, as 16, and steam or other expansible fluid is conducted from a generator through the pipe 14, to the jacket 11. The pressure of the fiuid may be fixed before it enters the ljacket or it may be regulated within the heat desired within the compartment may be fixed by the pressure of the expansible fluid in the manner abovedescribed. The degree of heat maintained within the compartment is dependent upon the product contained therein.

The products are thus subjected to this indirect heating process until the sterilization has been completed. rlhe compartment is then gradually cooled and the products withdrawn.

Any chemical, suitable for the purpose, but preferably tri-chloramin, may be employed as a stimulating element to the sterilization process, by placing the same in the trough `or pan 17. The fumes of the chemical, during the heating process, saturate the air within the compartment and thereby enhance thekoperation.

Variousrmodifications to the process herein described may be embodied without departing from the spirit of the invention and it is therefore not intended that this appli-v cation be limited to the particular form described.
