I haven't read what Mr. Gage wrote, but he probably meant a vacuum chamber with low pressure to kill the beetles. Not to crush them by force. Here is an article on that process:

Here is what the device Grainpro Cocoon (one of the methods used in the study) had to say happens:

GrainPro Cocoons™ are airtight (hermetic), unsupported rectangular structures made of lightweight UV resistant PVC. The simple two-piece Cocoon consists of a top cover and bottom floor piece joined together with a PVC tongue-&-groove zipper similar to those used to close environmental safety suits. Insects trapped in the bagged grain expire in a matter of days as a result of an increase in carbon dioxide and reduction of oxygen.
