PRODUCT OVERVIEW

Low Heat Grinding Built for Product Quality & Consistency

The Terp Preserve Grinder is the leading cannabis grinder available in both the high-capacity PSC-10 and the compact PSC-8 models, supporting different facility sizes, production needs, and output goals while delivering a clean, homogenized grind at scale.

By using a low-heat sifting method, it separates stems without degrading delicate terpenes or cannabinoids. The result is a homogenized, consistent grind that maximizes aroma, potency, and flavor.

Scaling Automation that Works for Cannabis Processing

“Game-changer”

“It’s been an absolute game-changer. The grinder runs at a slow speed and low temperature, which makes a huge difference. It used to take us 45 minutes to grind a 5-pound batch. Now, we’ve brought that down to a maximum of 7 minutes.”

Dakota, Seed of Life

“No real downtime”

“One of the best parts about Hefestus is their customer service. You don’t have to worry about being left hanging, they’ll call you back, and you’ll talk to a real person. If you need a part, there’s no real downtime because they include a full toolbox of spares. And if something else comes up, they’ll overnight it to you.”

“Running hands off quickly”

“Onboarding was extremely simple. Hefestus reached out, gave us an ETA of when the machine would arrive, and shortly thereafter when their team would arrive to onboard. By the end of the first day, my team was running hands off.”
