Tyvek Use

Can we safely say that tyvek is not going to melt if I pressure-cook it? I'm back to PF Tek today doing small jars for brazilian cubes. And do I need a double tyvek layer?

Are you making Tyvek lids? Just four holes and the vermiculite barrier should keep the brf mixture below it clean.

It is okay to use tyvek for some brown rice flour cake spawn but maybe don't call it PF tek it is confusing.
You can use tyvek filters instead of a dry verm layer, once you've inoculated the jar then you can carry on and follow the remainder of the PF tek.
They will be fine in the PC also.

Thanks, yeah, I was going to use tyvek under the lids of all the brf cake jars just as they go into the pressure cooker. The lids have each four holes for FAE. One central hole in the middle with RTV for inoculation. Is there a problem with that?

So is tyvek only usually used with grains then?

Generally.. it’s really of no use if you’re going to take it off right away after the pc’ing.

Well, no. The idea was not to take it off while pc'ing. What I'd thought to try was keeping the tyvek on, period. Then just using a central RTV injection point in the middle, if that makes sense. If this is not a good idea or an enhancement, please say why. Thanks.

Yeah don't open your jars once PC'd or boiled. Kinda defeats the purpose. But you can use it fun fun. But your gonna need to inoculate through the tyvek and I imagine it is just another area where you can possibly drag a contaminate through the hole with your needle.

Well, as I say, I was going to leave the four holes with the tyvek as air holes only and use a central hole in the middle for inoculation. But from what I'm reading here, the verm contam layer seems generally considered sufficient to keep out contams. But I see why grains are different cos we're not using verm.

Thanks.
