  1. Enerquip Introduces New Product Line – Compact Heat Exchangers

    Leave a Comment

    MEDFORD – Enerquip, a Wisconsin company that specializes in a wide variety of shell and tube heat exchangers, recently added a new line of compact heat exchangers to meet the growing demand from customers with low flow-rate applications.

    Enerquip has been one of the leading providers of heating and cooling equipment for production plants and the OEM’s and system integrators that support them. The company crafts stainless steel and high alloy shell and tube heat exchangers of the highest quality, with delivery lead-times that are half of the industry standard. The size of Enerquip heat exchangers can range from the size of a loaf of bread up to 10 tons.

    “Until now, we haven’t had an efficient solution for product flow rates from 1 to 10 gallons per minute,” explained Ron Herman, Director of Sales & Marketing. “These scaled down versions of our exchangers utilize smaller tubes that increase tube side velocities and turbulence, while avoiding problems with bypass seen in larger exchangers when they are used at low flow rates.”

    Available in both U-tube and straight tube designs, these space-saving exchangers are easy to clean, are high quality and built to last. Enerquip’s compact exchangers are also ASME code stamped, to provide customers with peace of mind that their product and their people will be safe during production.

    This new product line is perfect for small batch processes, point-of-use streams, or R&D or pilot scale applications where a smaller compact exchanger would be an advantage.

  2. Why floor space is vital for food processing facilities

    Food processing facilities have to ensure the highest safety standards while handling food products for consumption. Bacteria can grow in damp areas or on equipment if it is not properly cleaned. While this all might sound simple and basic enough, floor space is actually very critical to a processing plant’s operations.

    Easily cleanable materials

    The U.S. Food and Drug Administration’s Guidance Regulation report for Retail Food Protection explained that surface characteristics for indoor areas have to be both smooth and cleanable. The report added that areas that are highly prone to moisture such as food preparation areas, walk-in refrigerators, bathrooms or washing areas should have nonabsorbent surfaces for easier cleaning.

    “Walls and ceilings may be constructed of a material that protects the interior from the weather and windblown dust and debris,” the FDA report stated.

    Flooring and spacing

    The factory floor material should be smooth, waterproof and hard with an anti-slip finishing preventing injuries, the Food and Beverage Reporter stated. Additionally, some processing facilities that work with meat cutting should have cutting done in separate rooms to prevent any cross contamination on the facility’s other products.

    “In open food areas in particular, a high performance and functional floor which fulfills the requirements of the HACCP International Food Standard (IFS), those for volatile organic compounds (VOCs) and also workplace safety, forms the basis for quality and high-value products in the meat industry,” said Gary Johnson, business section manager for Performance Flooring, according to the source.

    The spaces in these areas have to be open so workers are able to move around heavy machinery and other large pieces of equipment, comfortably and safely. The open spaces also allow for easier cleaning so stray food products don’t get lost or avoided during cleaning periods.
    Certain pieces of equipment can take up large amounts of space in food processing facilities.

    However, larger critical pieces of equipment like shell and tube heat exchangers can be customized specifically to the facility to create more floor space throughout a manufacturing facility. They can also be mounted vertically, overhead, or in a mezzanine area.

    Handling multiple cleanings

    Flooring and process equipment has to be able to withstand numerous cleanings since sanitary practices are followed each and every day, since food processing facilities are able to build up bacteria quickly.

    “Puddling of cleaning solutions, if allowed to evaporate, may lead to deposits on the surface and ‘water marks’ which can be hard to remove subsequently,” Johnson said, according to Food and Beverage Reporter. “It follows that removal of cleaning solutions and adequate rinsing is required to keep your floor looking its best. Contaminants that could quickly spoil food must be removed with suitable processes in defined cleaning cycles.”

    Proper walkways and spaces

    For food processing facilities, finished food products could be contaminated when exposed to raw products nearby. According to Food and Agriculture Organization of the United Nations, facilities have to create appropriate walkways for unpackaged food and finished products so they do not rest or move around one another.

    To create these types of spaces, customizing heat exchangers to fit appropriately in the facility could clear enough room to make necessary walkways. When it comes to food preparation, sanitation, cleaning and efficient use of floor space are all necessary.

  3. Microbreweries gaining ground in the beer making industry

    In the last decade, the number of microbreweries filling Americans’ pint glasses has skyrocketed. According to the U.S. Brewers Association, 24% ($22.2 billion) of the beer market belongs to microbreweries.

    With the market growing and competition expanding, breweries have to invest in processing equipment that will bring a return on investment. One of the most common pieces of equipment is a shell and tube heat exchanger.

    When using a heat exchanger where two liquids are involved, the heat exchanger uses heat from one fluid in the shell of the exchanger to warm or cool the other liquid in the tubes of the exchanger.

    The main purpose of this in brewing is to kill the bacteria in yeast, one of the main ingredients in beer. The bacteria in most yeasts in the beer need to be boiled first and cooled afterward. Also, the bacteria is known as thermophilic, meaning it can withstand higher temperatures.

    Having a custom shell and tube heat exchanger allows breweries to reach proper temperatures to kill off the bacteria without damaging the state of the product. According to Serious Eats, there is such a thing as “friendly yeast,” which can be introduced to add numerous flavors while breaking down the sugar.

    Heating these products can kill off the appropriate yeast needed to craft beer. According to Brew Like a Pro, cleaning and sanitation is essential for the “cool side” of the beer-making process because the thermophilic bacteria can multiply and double every 20 minutes.

    The brewing process can be greatly affected by the rolling action of the boil. The heating process needs to be relatively precise, which calls for custom heat exchanger solutions.
