We began our journey in September, 1997 and since then, Solids Handling Technologies has grown to become a renowned bulk solids handling consulting firm. We stand

by our motto Expertise, Integrity, Reliability as we pride ourselves on providing bulk solids testing services and practical design recommendations to solve our client’s flow problems. We look forward to providing these services and working with our clients for years to come.


Solids Handling Technologies, Inc. provides testing and consulting services to all bulk solids handling markets.  Flow properties tests are conducted on a Jenike Shear Tester.  Consulting services include the evaluation of bulk solids flow properties and the generation of recommendations for bin and feeder designs to ensure reliable solids flow.

Joseph Marinelli has been providing consulting services since the early 1970’s.  As a former consultant with Jenike & Johanson, Inc., he has years of experience testing solids and designing bins and feeders for reliable flow.  Mr. Marinelli lectures frequently on the topic and has published several articles including a chapter in a chemical encyclopedia and food technology book.

Solids Handling Technologies’ expertise ranges from developing test programs and evaluating test results, to designing bins and feeders to solve complex solids flow issues.  Objective, practical recommendations to ensure reliable material flow are essential to our position as consultants


The field of bulk solids handling was developed due mainly to the work of Dr. Andrew W. Jenike, who pioneered the theory of bulk solids flow.  Working with Dr. Jenike in the early 1970’s provided a strong base and we have been providing consulting services and solutions to solids handling problems since then.

Our primary emphasis is to resolve problems experienced by those industries required to handle bulk solids, such as: chemical, food, plastics, pharmaceuticals, power and many more.

We are committed to providing practical consulting services to clients with difficult solids handling problems.  The scientific approach to the storage and flow of bulk solids that was developed by Dr. Jenike in the 1950’s, is still relevant today.  This approach is the standard today through ASTM for measuring bulk solids flow properties.  We stand by our recommendations having developed a reputation based on reliable, practical solutions to industry problems.


There is a fundamental difference between the customer of a manufacturer and client of a consultant. Having been exposed to both areas of the industry allows a unique approach to our consulting business. Practical solutions are required to solve a client’s problems and our manufacturing experience enables us to provide practical, economical, reliable design recommendations.
