Claims16
A process for the preparation of sterilized plant matter comprising the steps of:
- a. treating coarse chopped plant matter with heat to achieve dehydration;
- b. compression filling airtight fiber reinforced plastic bags with the still heated dehydrated plant matter;
- c. injecting high pressure steam into the heated dehydrated plant matter while in the bag, the size of the bag being such that the high pressure steam can completely and sufficiently penetrate through the heated dehydrated plant matter to attain temperatures sufficient to achieve sterilization;
- and
- d. sealing the bag whereby the temperatures in the bag are maintained for sufficient time duration to achieve sterilization, and condensing steam is absorbed by the dehydrated plant matter to create vacuum conditions in the bag.
