Industrial Hemp Dryer

Step 1: Conveying

Fresh off the field or out of bales, hemp is moved from its staging area by one of several conveying methods depending on the state of the product and the facility. It then passes by magnets to remove any metal that may have been picked up in the field and is fed into the shredder. It is then conveyed once more over a weighbelt, which uses product weight and conveyance speed to control the feed rate of the entire line and precisely meter the shredded hemp into the dryer.

Step 2: Shredding

Shredders ensure consistent particle sizes that can be dried at consistent rates. Shredders are used instead of mills because they slice the product instead of mashing or crushing it. Crushing wet product means two things: particulates get in every crevice and are hard to remove, and the product is compressed, reducing the efficiency of the drying process. Once out of the shredder, product is discharged and conveyed to the dryer.

Inconsistent product means wet spots. Wet spots mean either mold or over-drying product to get rid of them. Product must be homogenized.

Biomass Dryers

hemp drying system

Fluid bed drying is a well-established method in the food processing industry and is just now successfully being applied to hemp. This is because the hemp application is tricky and there are a lot of “moving parts”. Fluid bed dryers operate by passing hemp over vibrating screens while forcing air up through it, suspending the hemp like ping-pong balls over air streams. Because it uses much less heat than tumble dryers you see significantly less product degradation, and because it exposes biomass to much more air per cfm pulled, it uses less energy than belt dryers. A fluid bed system will cost 1/10th – 1/2 the amount to operate than the previous methods, is smaller, is cheaper up-front, and it retains more of all of the desirables. Whereas tumbler and belt dryers collect keef on the equipment and lose it to the atmosphere, fluid bed dryers capture the volatiles and either return them to each batch in real-time or collect them for use. Sizes of machines vary, and the largest dry 10,000 lbs of biomass per hour.

Whole Flower Dryers

Medium size hemp microwave dryer

Microwave dryers operate under vacuum and slowly and evenly heat hemp while gently cycling it with specialized paddles. Because microwaves permeate all the product at once, particle size reduction is unnecessary, making this method ideal for smokeable, whole flower. The largest microwave dryers top out at 1,000 lbs/hr and have a number of benefits related to its ability to hold precise temperatures throughout the entire product with less than a degree variation in temperature. Not only does this allow decarbing of pellets, for example, but it allows terpenes to be pulled and collected based on evaporation point.

CBD/THC Retention

lbs/hr max/unit

Our drying units lead the promotion of our systems by a slim margin. Our separation and packaging systems save tons of man-power and perform BETTER with machine-run product than hang-dried and hand-chopped.

ABM has reliably and consistently elevated [our] ability to maximize performance and subsequent yields from plants to refined goods. We hope to keep them busy enough that none of you competitors can get them on the schedule.

Step 4: Separation

Dried biomass is not only less sticky, allowing it to inherently move more freely, but the more fibrous stalks retain much of their size through drying while the premium product shrinks. Because the size difference between the materials increases, they are mechanically easier to separate. Using specialized sifters, our system can separate premium product from stalks with near-perfect precision, as shown in the slider above.

Step 5: Packaging

In the last step of this continuous process, bulk bag fillers package the dried cannabis into bulk bags, drums, or totes. Surge hoppers are placed above the bulk bag fillers to allow for smooth changing of containers without interrupting the continuous flow of product. Our systems are meant to interface seamlessly with other equipment and perform with minimum labor involvement or interruptions.
