Freeze Dryers and Vacuum Dryers

It is impossible to overstate the significance of freeze dryers in the current bubble hash method. Cannabis growers, as well as businesses in the food, pharmaceutical, and many other industries, depend on freeze drying. Products that are freeze-dried have several advantages for businesses, including a longer shelf life and product variety. It is not ideal for businesses, especially those who create bubble hash and ice water hash, to use air drying, which was the conventional method of drying bubble hash in the past.

As a result, some opt to speed up the procedure. Although this adjustment frequently yields favorable results, it is not exactly freeze drying, leaving producers caught between two useful but frequently ineffective techniques.

The main difference between vacuum drying and freeze-drying is that vacuum drying eliminates the freezing stage, which can result in compromised product quality.

What Is Freeze Drying?

The technique of lyophilization, often known as freeze drying, involves freezing perishable goods to remove the water. A freeze dryer is an essential component in the cannabis industry for creating dry ice water hash or bubble hash.

First, the material is frozen inside the freeze dryer. After that, the dryer's internal pressure is reduced while heat is gradually supplied. The source material's frozen water can change from a solid to a gas without becoming a liquid thanks to the heat. Sublimation is the name of this procedure. After that, there is another drying process.

Overall, traditionally, freeze drying is a three-step process:

Freezing: Considered the most important step by many, the material is frozen below its triple point, or the temperature and pressure where the sublimation curve, fusion curve, and vaporization curve intersect.

Primary Drying: The sublimation phase, which lowers the pressure while adding heat inside the freeze dryer, This step can take a good deal of time as it removes the vast majority of the water in the material.

Secondary Drying: Referred to as the adsorption phase, this is where water molecules are removed from the material.

While effective, a full freeze-dry cycle on pharmaceutical-grade lab equipment usually is a two- to three-day process. Its slow process leaves some producers turning to shorter freeze-drying methods, sometimes totaling less than a day. While it may seem like this is suitable, some believe that this is actually closer to vacuum drying.

What Is Vacuum Drying?

When making bubble hash or ice water hash, timing is important. Therefore, even though many businesses explore freeze drying, the vacuum drying procedure frequently receives preference from these businesses.

Reduced pressure during vacuum drying decreases the machine's temperature. These procedures enable the material to dry considerably more quickly than would normally be possible via a good freeze-drying process. Producers can use the method to hasten production while preserving energy. In principle, the strategy enables a business to reduce energy costs and turnaround times for items, enabling them to make cost savings and generate more money overall.

Like freeze drying, vacuum drying is a three-step process that includes a freezing phase followed by a sublimation step and then a secondary drying phase. Virtually all Harvest Right freeze dryers dry via vacuum drying, not freeze drying.

Consider This…

The technique of producing dry hash is currently being thoroughly investigated. There is still much to learn about the techniques and technology employed to produce its effects. Since the technology is still in its infancy, we anticipate that this learning process will last a while until we completely comprehend the procedure and its optimal approaches. Producers must be aware of the best procedures for their industry in the meantime and be ready to change if necessary.

Therefore, even though producers may be able to get greater results by lengthening their dry durations, some may assert that the one-day or less procedure is adequate for the manufacture of bubble hash and ice water hash.
