Pick Heaters has been an industry leader for over 75 years. Read about applications, technical information and best practices provided by our experts.
Pick Heaters used a unique approach to meet the requirements of a specific customer and in the process hit upon a system design with an unprecedented degree of utility. The system has since been duplicated and adapted for numerous other customers with similar needs.
One effective method to consider for processing heated pet food products or supplements is through the use of the Direct Steam Injection (DSI) System.
When considering a new process line, production facilities should examine the type of Direct Steam Injection Heater used. Many think of the jet cooking equipment as simply a high shear device, but that couldn’t be further from the truth, and when maximizing production, high shear isn’t always the best approach.
The challenges of heating fluids and providing a steady hot water supply are important to a wide range of industry types, and there are many solutions that engineers employ to meet those challenges. Not all solutions are equal, however; following a selection path designed to save up-front costs may not always be the best strategy. There are numerous factors to consider, including ones that may be less obvious.
The limits to indirect heat exchange examined in Part 1 become more significant as greater temperature or pressure is required for heat and hot water applications. In many cases, the solution for design engineers is to opt instead for direct steam injection (DSI).
Among the most important aspects of any food, beverage or pharmaceutical processing operation is the ongoing assurance of sanitary equipment. Effective cleaning is the best defense against product contamination — something to be avoided not only for health and safety reasons, but also for its ability to impact brand perception and raise the specter of lawsuits and product recalls.
Most brown grease from waste traps has historically ended up as landfill, but recognition of its value for production of fertilizer, biodiesel and other products, as well as more stringent EPA regulations, are driving a trend of brown grease recycling.
Sanitization is critical to food production. Food production machines need to be sterile, or the food could potentially become contaminated. There are many ways to ensure food safety, and among them is direct steam injection (DSI).
Food production is a process that must be hygienic from start to finish. From the utensils to the equipment to the packaging, everything needs to be clean to ensure that the product will be fresh and sanitary for the customer. One of the most important steps of this process is gas injection, which is used to both manufacture and package food.
The most common method of transferring energy with steam is indirect heat exchange, which has a significant drawback. Due to the pressure drop as the condensate exits the trap, some portion is inevitably lost to flash evaporation. As the condensate is lost, system efficiency is impacted. There is an alternative method that is ideal for high-pressure systems: direct steam injection (DSI) which achieves 100% heat transfer efficiency.
Steam still has an important role to play in jacketed heating, but a Direct Steam Injection (DSI) Heater provides the most precise and energy-efficient method for heating the jacket water to the desired temperature.
Customers have many choices for heating water, liquids or slurries, but Direct Steam Injection (DSI) Heaters should be at the top of the list of options for these challenging applications.
Steam is capable of transferring a large amount of heat to materials used in food and beverage processing, and it can be precisely controlled to within narrow temperature ranges. It can be applied directly to the materials being heated (through direct steam injection or DSI), or it can be applied indirectly through the use of heat exchangers that incorporate plates or tubes to segregate steam and process fluid.
A Direct Steam Injection System can rapidly and accurately maintain temperatures for processing difficult materials, such as wastewater, and thereby increase the efficiency and reliability of the anaerobic digestion system.
While digging through the Pick factory archives the other day, I came across a 14-page pamphlet titled Industrial Water Heating – Methods and Means. The booklet covered the basic methods of providing hot water for industrial uses. It also explained the difference between heating water through direct steam injection and the in...
An ongoing challenge faced by food industry customers is maintaining a reliable, yet safe plant sanitation system. This means making sure that all areas of the plant have hot water at the required temperatures regardless of load. Precise temperature control at the necessary volume needs to be available whether during peak load clean-...
Previously, we compared two methods of heating water for plant sanitation, both involving DSI (direct steam injection). While the use of individual steam-water mixing tees offer many conveniences, there are some shortcomings with efficiencies and safety. The Pick alternative is the installation of a centrally located, Variable Flow h...
In this last in a series of Pick Blogs covering methods of heating water for plant sanitation, we take a look at direct contact hot water heaters. These systems typically incorporate a cylindrical stack with an internal diffuser near the top, a burner section and a water collection reservoir at the bottom. Water is sprayed onto the diffuse...
