About PST

Engineering reliability for food processing—starting with grain milling.

We believe food production must become more efficient, more reliable, and more resilient—because the world is changing faster than ever.

Global population continues to grow. Natural resources are under pressure. Supply chains are increasingly fragile. Economic instability and conflict create uncertainty in food availability. In this environment, food processing is not just an industry—it is stability.

PST is an engineering and manufacturing company with 50+ years of industrial experience across automotive, medical, construction, heavy transportation, aerospace, and defense. We have built components and systems for environments where failure is not acceptable—where precision, repeatability, and disciplined quality control are fundamental.

Today, PST is applying that capability to the food industry, starting with grain milling.

Why
Grain Milling?

Grain milling sits at the center of global food supply. Small improvements—less loss, higher stability, better consistency—scale into meaningful impact across thousands of mills and millions of tons of grain.

Yet many critical consumables and process components in milling were designed for a different era. We see clear opportunities where engineering can replace variability with reliability, and where better design can reduce waste while improving operational confidence.

Multisift:
the first fruit of our strategy

Multisift

Multisift is the first product line of PST’s food-industry transformation. It is built to raise standards in milling through repeatability, clean operation, and process stability—validated in real mill environments and refined through continuous improvement.
