  • Hapman Systems Designed to Handle the Job Vacuum Conveyor System

    Major/Minor Dry Material Vacuum Batching System Systems Designed to Handle the Job Vacuum Conveyor System Major Ingredient Handling:  Bulk Bag Unloaders - Each is equipped with a 2 ton electric hoist and pneumatic bag agitation for efficient material   flow. The unloaders have load cells for the accurate, real-time measurement of material flowing out of the FIBC’s   (loss-in-weight). Each bulk bag unloader also contains a bag tie box for full-flow shut-off prior to full bag emptying. Gravimetric Screw Feeders – located at the discharge of each bulk bag unloader, the feeders meter the flow of material to  an accuracy of +/- 1%. Actuated diverting valves open to the percent required to meet the formula call for material.

  • Hapman APPLICATION REVIEW Food Processor

    Overcoming the Challenges of Handling Salt  in Bulk - The Moisture Absorbing Nature of Salt   Italian Food Processor Expands Pasta Line Purchasing in bulk bags or FIBC’s is a cost effective way for most process manufacturers to buy dry bulk materials. The cost of the material per pound is typically less when buying in bulk, storage of raw material requires less floor space, and the handling of bulk bags is more efficient by using fork lifts and bag unloading stations as opposed to operators manually dumping smaller bags into dump sta- tions or hoppers. Some materials can cause unexpected challenges when purchasing in bulk however. The molecu- lar construction of the dry material and its ability to attract moisture from the air and become compacted can create issues for processors. Salt is a compound mineral that can be hygroscopic in some forms resulting in caking and clumping (http://en.wikipedia.org/wiki/Salt).  

  • HAPMAN CASE STUDY Wastewater Treatment

    The Village of Gilberts, IL Achieves Wastewater Requirements with the  Help of Baxter & Woodman’s Innovative Pre-Treatment System Design   Harry Harman, P.E. of Baxter & Woodman, consulting  Engineers, received a call from an official with the  Village of Gilberts in the State of Illinois. The call was  a request for a review of documents from the EPA to  the Village regarding the 5 year renewal of the Village’s  National Pollution Discharge Elimination System (NPDES)  Permit. The Permit, is a set of standards developed by  the Environmental Protection Agency (EPA) for the  management of wastewater contaminant concentrations  allowed to be discharged into streams and rivers by  industry and public wastewater treatment facilities by  cities, villages, and townships. Upon review of the report,  Harry immediately noticed a more stringent limit on the  permissible levels of Barium. There were no treatment  systems available which would remove the Barium without  exceeding the recently enacted Radium limits established  by the Illinois Emergency Management Agency – Division  of Nuclear Safety.

    Find solutions to your toughest handling challenges. It can be tough to convey powders and bulk solids to where you need them. That’s  why Hapman engineers continually find better, more cost-efficient ways to move  materials. Those solutions can help you eliminate:   Bulk material handling systems. Unlike liquid or gaseous systems, the flow dynamics of bulk material systems is not static. Bulk Density and flow  characteristics can change throughout the material handling process creating challenges and process inefficiencies.  Our experienced team can design and build a complete material handling system with integrated controls to save  time and money,  and avoid loss of production. Below are just a few examples of the innovative systems we have  designed and built for customers in a range of industries.

    U.S. Mechanical Engineering Job Outlook

    Experienced and future mechanical engineers take note - The future looks bright. This new Powder & Bulk Solids (PBS) whitepaper examines the the employment outlook for mechanical engineers in the United States through 2024, offering a glimpse at opportunities in the field in the decades ahead. Job creation in the U.S. for roles occupied by mechanical engineers is projected to remain steady through 2024 as changes in population, technology, and manufacturing create demand for MEs with citting-edge knowledge. Some highlights from Powder & Bulk Solids' survey of employment prospects through the early 2020s include: - Nano medicine, nanotechnology, bioengineering/biomedical engineering, smart materials, and renewable energy are predicted to be top emerging fields for mechanical engineers through the 2030s - Space exploration efforts, increasingly undertaken by private companies in the U.S., may also provide new employment opportunities - Architectural, Engineering, and Related Services employed the most mechanical engineers in May 2015 - U.S. News and World Report ranked mechanical engineering as #2 in its Best Engineering Jobs of 2017 list - Growth in the smart materials industry may create employment opportunities Register now for free to download this whitepaper and learn more about the future of mechanical engineering in the United States.

  • Powder & Bulk Solids examines the employment outlook for chemical engineers in North America through the early 2020s.

    North America Chemical Engineering Job Outlook

    Whether you are a seasoned chemical engineer or fresh out of university entering the field, Powder & Bulk Solids' newest whitepaper on the employment outlook for chemical engineers in North America will provide insights on the industries where chemical engineers work, the projected job market moving into the 2020s, and a glimpse at potential hiring trends over the next few years. Though job creation for roles occupied by chemical engineers is projected to remain sluggish in the U.S. through 2024, many new exciting opportunties are arising, fuelling the development of new jobs, and the pending retirement of thousands of baby boomers will open a number of positions. In Canada, thousands of new jobs for chemical engineers are forecasted to be created through 2024. Some highlights from Powder & Bulk Solids' survey of employment prospects through the early 2020s include: - Pharmaceutical and biotechnology firms are increasingly hiring chemical engineers - Chemical engineers remain one of the highest paid occupations among all engineering categories - The engineering services industry employs the most (36%) chemical engineers in the U.S. out of any industry - 37% of new chemical engineering jobs created in Canada through 2024 will result from expansion demand - Global employment of chemical engineers is expected to remain stable through the early 2020s Register now for free to download this whitepaper and learn what the road ahead looks like for chemical engineering employment.

  • Hapman Presents Case Study on Automated Transfer Process

    The Challenge Manually shoveling sand to fill cope and drag boxes  (casting flask) for sand casting is a physically demanding  process for mold makers, who on average shovel 20 tons  of casting sand weighing 100 lbs. per cubic foot into 70-80  molds per day. This demanding operating condition creates  a high level of physical strain on the mold maker’s body.  The result of this strain was a multi-million-dollar-per-year  workers compensation obligation for an aluminum foundry.  The financial impact not only hit the company’s bottom  line but slowed overall worker efficiency. Company leaders  knew that keeping workers safe and healthy was not only  important for their people and profits but also for their  customers. They knew if they could improve productivity  through process improvements, they could reduce lead  times and improve customer satisfaction, which in turn  would continue to grow their business. After many searches  on Google and conversations with various material- handling companies, foundry management discovered  Hapman.
