What is the footprint of the Mesclatore? What size room do you recommend?
The system is 64” L x 48” W x 92” H, and individually the trolleys are 41” L x 31.5” W x 41” H.
The minimum space we recommend for operating the system, not including other ancillaries, is 160” L x 80” W and 8 foot ceiling.
How many pounds can you wash per batch?
If dry trim, 6-8 pounds (3.6kg).
If fresh frozen flower, 44 pounds (20kg) if making a food grade product.
Full Melt's recommended maximum is 22 pounds (10kg).
These are real numbers and not marketing fluff.
How much time does a typical batch take to wash?
Between 45 minutes and 90 minutes, depending on SOP.
How much biomass can you wash in a shift?
This varies considerably based on SOP. Typically, 6-8 batches can be washed per shift. That means as much as 64 pounds of dry trim and 125 pounds of Full Melt Fresh frozen.
What are the yields on the Mesclatore VS other methods or equipment?
Yields are cultivar dependent. The next most important factor is the supply chain and handling of biomass. All things being equal, in some cases, we found the Mesclatore to yield as much as double what hand wash methods yield. This can be attributed to employee fatigue (but possibly other variables as well, all difficult to measure). We usually saw this happen during night shifts with less supervision. Automation removes this variable from the equation without sacrificing quality.
Compared to competitors, we tested the LowTemp Osprey and consistently had 8% higher Yields to rosin. Icextracts, Hashatron and Hashtek, seem to have higher yields to dry hash but not to rosin. This is likely due to the extraction of contaminants and stalks that don’t report when pressing for rosin. We have not tested other systems at the time of writing this article.
How are yields calculated, and what is the most important metric?
Yield is calculated as the weight of dry hash in relation to the feed. This means that if 10,000 grams of fresh frozen flower produced 300 grams of dry hash, the yield is 3%.
However, because contaminants such as particulate and stalks can inflate this number, yielding to pressed rosin is more accurate. Contaminants do not add value to the hash or rosin, just volume or weight to the hash. When pressing for rosin, never does the rosin weight equal to the hash weight. Pressing is both an extraction process and a filtration process. Yield to rosin is a better metric as it mainly eliminates contaminants from the hash. This is why you may see a 70% yield when pressing to rosin, meaning that 30% of the hash likely was stalks or other contaminants.
Therefore, if the final rosin weight is 210 grams, the actual yield from the 10,000 grams of biomass was 2.1% and not 3%, as previously suggested. The lost 90 grams were mostly contaminants and stalks.
Can you recirculate the wash water or is this system only drain-to-waste?
The Mesclatore was designed with re-circulation in mind, and does so effectively. However, if your SOP calls for drain-to-waste this is efficiently achieved.
Why is water quality important?
Water is the extraction medium, both chemically and mechanically. Chemically it extracts terpenes, anthocyanins, and other impurities from the flower. Water is also essential in the mechanical separation of trichomes by creating the conditions for shear to assist in decapitating trichomes. PH, Temperature, and Osmolality of water play critical roles in the process and thus should be monitored and optimized to avoid damaging trichomes. The viscosity of water plays a critical role in decapitation and the power requirements of the agitator. Water is the common factor in all these variables, so understanding its behavior is critical to the process.
