I started this thread on the old site. Continuing it over here.

I was in a rush because my son was coming to town and I didn’t want him to find 7 bags of bud in the freezer. So I did 2 batches in 2 hours. If I had time for a a 4th and 5th wash I would have gotten more hash. I’m still washing in a bucket and agitating with a paint stirrer, until I find the right washing machine. I sieved with 190u and 45u bags only. I’ll try drying this batch with my home-made freeze drying setup in a separate post. For now it’s frozen.

Have you seen people using vacuum cleaners to dry fresh froze hash? Sounds kind of funny, but it seemed to have worked I think it will take a terp hit though.

You got the better of that batch Mara, forget the 4th-5th washings 
Nice yummy looking brick there, is it a mix of straight cultivar stuff?
Maybe change the sieve grades though? I have a Bubble Bowl dry ice kit I use for hashing which starts at 160um, into 120, then 90… 120 catches the bulk of material, 90 a variably small slice, past that it’s usually just dust…
What grades does your b’bags kit have? …slipping a middle grade between the 190 and 45 might be beneficial…
The BBowl kit isn’t very efficient, but I don’t really care… because the dry ice tends to make material brittle, over-processing is always a concern… I love this method because it preserves the terp’s so well!
I’m always amazed at how variable the textures can be… A few cultivars seemed unbindable, to “dry”, simply would not adhere together. 
A few were just the opposite, like half set epoxy, so oily soft they needed to be put on a bud bed or it’d just melt through the screen!
Had some very taffy-like stuff too, a trip to feel

Yeah, bubble bowls are not super efficient, but they definitely preserve the Terps very well!
It definitely depends on the strain, but I normally do a three minute shake in collecting in the bowls and then I shake onto a platter until I see a hint of color, but I’m real conservative.
I like high quality, so there’s quite a bit of medicine left in the material. I spread the work material over my aluminum trays and let them dry. I have a fan to move air around but not directly pointed at the aluminum trays. Once or twice a day I will go and stir the material to even the drying.
Once it dries I will run all the material through Decarb and infused cycles until it’s all done. I take the oil from one infusion and use it on the next infusion And add fresh to make up from the loss of the first. I limited to two infusions, the initial infusion and two additional. The oil does get stronger with each infusion, but anything past 3 infusions really makes too strong of a tasting oil. And that strongness is mainly chlorophyll. And this doesn’t have enough time to decompose.
It works fine in making edibles or adding to your coffee.
I wish somebody would start making bubble bowls again! I think it’s an easier and far less messier way that more people could experience making their own hash from their home grown.

The little brick in the first post was dry sift from my Trim-Bin that I pressed in a Rosineer 1.5” x 1.5” pre-press. It was a mix of strains that accumulated over a year or so. Very nice.
I got the set of 5-gallon bags in 8 meshes from Gutenberg ($50). They threw in the small square of 220u mesh which is handy for collecting the results. It’s stretched across the wife’s embroidery hoop (red hoop in the first batch of photos). I started with 190u and 45u based on a Frenchy Cannoli article or maybe video. He recommended that combo for people who are going to mix the different grades together in the end anyway (190 to catch the bud, and 45 gets most sizes of trichomes).

Yes, I saw a couple of videos where they put a vacuum cleaner hose under the 220u collection screen to suck water out to shorten the drying process. I tried it with the wife’s vacuum cleaner. It did remove some water, but pulling the hose off the screen bounced some hash onto the floor. I’m hoping that using a vacuum pump hooked up to a vacuum chamber in the deep freeze will get rid of the moisture quickly while preventing oxidation.

Were bubble bowls for making dry sift?

No they were made to use with dry ice and fresh froze buds.
I would love to be able to do I ice water hash. I really don’t have a place that I can bring the temperatures down and still have Relative ease of access to water. And I think kinda even more importantly, I’m just not gonna deal with Drying that wet hash without the proper dehydrator, especially with the amounts that I would do.
Now, some say that they have had success in drying their ice water hash in a Cannatrol. I’d have to see it done before I would attempt it.
But realistically, i’m probably not going go that route until I build my grow room in my shop. With that set up I’ll be able to control the temperature and have easy access to water. If I’m going to go to the trouble of buying a dehydrator, then my wash setup is gonna nice also.
The dry ice does produce a very high quality product, either Temple Balls or in live rosin. The hash only has to dry out being cold and the atmospheric moisture condensing on it.
Clean up pretty easy too!

Hey @Mara_Cachafa , good to see you over here. I am curious about your diy freeze drying setup. If you do a thread on it, I will be there. I have tried it with food, and it did not work well, but I didn’t spend a lot of time with it. One thing that I found is that with my rotary vane vacuum pump, the moisture quickly contaminated the oil, which was a pain because the drying process was so slow. Would love to see how you set this up.

Yup, trim and buds… I break the dry ice up into small pieces, this seems help reduce the powdering effect that happens with dry ice and agitation. You can sift a bit longer and get more material out.

Oh, and of course it is really nice to see you over here too. This place is coming together.

My setup is a rotary vane pump like they use for refrigeration, hooked up to a vacuum chamber in the deep freezer. The first time I ran it, it filled the basement with an oil mist, so I need to vent it outside before I crank it up again. I used to have a bigger oil-less vacuum pump with graphite vanes that I used for drying balsa core in fiberglass boat hulls. That would have been ideal, but it’s long gone. It was a $500 pump, but I got for $0.10 a pound at my friend’s junkyard!

I solved the oil mist problem by making a foam adapter which fit over the outlet, and also had a smaller hole into which I stick a section of garden hose. I lead the hose into a flush toilet, pushing it far enough to get past the trap, and all the oil mist goes out the sewer vent. This handles the freeze drying issue because my freezer is only 15 feet or so from the downstairs laundry/bathroom. If I need to use the pump in my shop, I lead the hose out a window through an insert of styrofoam that the window slides closed on.
The problem with the freeze drying effort is that doing food takes a long time, and automating the pump is hard. No matter how hard I try there is always a very slight loss of vaccuum, and that means that the pump needs to be controlled by a vaccuum switch. If as sometimes happens, the pump fails to start (sometimes the initial resistance overcomes the inital torque, not often, but it happens), the pump locks with power on and no rpm, so no pumping, and more importantly, no fan cooling. So far, I have not figured out a solution that protects the pump from overheating if it locks up, or dealing with serious water contamination of the oil. I am not sure I will chase this any further than I have. The ideal would be a different pump design with no oil, and zero chance of lockup, but that ain’t gonna hoppen due to price.
