Hygienic Systems Industry

Process Design of Sanitary and Hygienic Process Systems

EPIC utilizes an isolated hygienic fabrication shop and a team of highly experienced engineers to design, build and validate hygienic systems. From the first design stages through equipment selection, hygienic systems fabrication, installation and startup, EPIC is committed to properly validating process systems that will meet all applicable standards for years to come.

When validating hygienic systems, EPIC considers the following: proper slope & drainage, microbial elimination, FDA requirements, IQ/OQ standards, 3-A, USDA, cGMP, ASME 9U&R), BPE, API standards.

Hygienic Process System Examples

Hygienic Process  System Design & Fabrication for Multinational Pharmaceutical Company:

EPIC designed and fabricated ten sanitary process systems for a multinational pharmaceutical company that recently announced a $2-billion expansion of their medicine-manufacturing operations. EPIC provided design-build services for two solvent recovery hygienic process systems and eight mixing sanitary process systems. All sanitary and hygienic process systems were designed at EPIC and subsequently fabricated, inspected and Factory Acceptance Tested (FAT) in EPIC’s isolated sanitary fabrication shop.

  • Key Features: special consideration was given to ASME BPE requirements, materials of construction, traceability, hygienic liquids blending, inspection and physical design restrictions, hygienic process skid.

Turnkey Medical Device Assembly Machine:

EPIC designed an automated process to assemble medical devices without human interaction

EPIC designed an automated process to assemble medical devices without human interaction. Our team handled the design, assembly, transport, installation, and integration of the device into our client’s existing manufacturing ecosystem. The completed system assembled several parts of an injectable device into a complete unit in a fully automated hygienic assembly system.

  • Key features:Hygienic assembly and packaging for 20ppm, Custom rotary table, conveyors and loading stations, Custom air control system, machine vision inspection system

CIP System Industrial Automation System Design, Control Modification, & Expansion:

This project posed the unique challenge of re-engineering a faulty control system while ensuring a pharmaceutical grade operating environment. EPIC handled the 8,000 pages worth of documentation, checkout process, and ad validation for the operating environment, and completely redesigned the control system. The result was a fully automated, highly efficient CIP system that increased productivity corrected all control errors, and complied with FDA regulations.

  • Key features: 2 integrated clean-in-place systems, 3 Allen Bradley control panels, InBatch by WonderWare software, validation documentation, hygienic liquids blending

Advantages of Working With EPIC

The advantages EPIC brings to any sanitary or hygienic process systems project include:

  • Experienced sanitary process engineers – We’ve worked as integrators and clients in hygienic manufacturing environments, giving us a better understanding of the complex chemical interactions involved in your process.
  • A dedicated sanitary fabrication shop – Built to fabricate hygienic and sanitary process equipment, our shop is staffed with a team of skilled craftsmen who deliver high-quality work in a controlled manufacturing environment.
  • An in-house quality team – Our QA team inspects every weld and performs system testing before shipment. Our detailed green-tag process ensures every aspect of your project has been reviewed and meets all applicable quality standards.
  • Thorough specification & documentation process – We ensure a safe, quality system ready for validation covering everything from welds to electrical wiring.
  • Proven solutions & a design-build process – This means your process systems maintain tightly specified recipes during production and the high-quality standards expected by the FDA and other regulatory bodies.


EPIC designs, automates and fabricates your custom sanitary process systems with decades of company experience, hygienic systems fabrication, and access to modular systems that get the job done efficiently and accurately. With a single point of contact to keep things moving forward, you will always feel in control as you move through the process.

During project development, we help you address challenges such as:

System design, including:

  • Optimal distributions and feed rates for raw materials using predictive models of unit operations
  • Optimal operating ranges to achieve product CQA through modeling of degradant formation & polymorphs and all other relevant chemical interactions
  • Modeling and calibration of internal process variables such as formula composition, particle size distributions, powder properties, heat transfer, slope-to-drain load, etc.
  • Development of practical controls strategies based on the range of expected manipulated variables, production risks, budget, and safety standards.
  • Refinement of product quality standards and sampling point baselines
  • Finite Elemental Analysis (FEA) upon request

Equipment selection, designed to:

  • Prevent cross contamination
  • Allow for optimal clean-in-place capabilities
  • Promote drainage and discourage bacterial/microbial growth
