Assessing product properties for optimal heat exchanger performance
In every situation where a heat exchanger is required, the combination of products and service fluids, application, temperature and other variables will be different. Understanding these properties ensures the correct heat exchanger is supplied. For example, high fouling materials may require a scraped-surface unit. Having adequate information will also ensure that the heat exchange process does ...

The benefits of heat regeneration in heat exchanger systems
Heat exchangers which employ heat recovery or regeneration should not be confused with ‘regenerative heat exchangers,’ which are a specific type of heat exchanger. What we mean by heat regeneration at HRS is the recovery of as much surplus heat (or cooling capacity) as possible after the primary function of the heat exchanger has been performed. This can then be reused to either ...

Preventing product contamination with double tube plate heat exchangers
Ensuring product safety is the number one priority for any producer of pharmaceutical products, and a key aspect of this is avoiding contamination during production. Design and construction plays a key role in achieving this, and the heat exchangers used for processes such as pasteurisation and sterilisation are no exception. There are three main elements to preventing contamination occurring in ...

Removable Plate Heat Exchanger
The removable plate heat exchanger is mainly composed of heat transfer plate, sealing gasket, pressure plate at both ends, clamping bolt, bracket, flange or bushing, and ground foot. Heat transfer plate is the main component of heat exchanger. Generally, corrugated heat transfer plate is made of herringbone. According to the different fluid medium, the material of heat transfer plate is ...

Advantages of plate heat exchanger
1. The heat transfer coefficient of plate heat exchanger is higher than that of other heat exchangers. When designing plate heat exchangers, some special corrugates are designed on the plates. Never underestimate the role of these corrugates. They can make the fluid flow with strong turbulence at very low flow rates. The self-purification effect of turbulence can prevent fouling. The heat ...

Choosing the Right Heat Exchanger for Food Processing
All but the most basic heat exchangers are created to a bespoke brief, designed to take into account the material/s being heated or cooled, the heating or cooling medium, the amount of product being processed, product velocity, risk of fouling and a host of other factors. However, over the years some standard design types have emerged (as well as more specific types) and understanding the ...

The Role of Heat Exchangers in Apple Juice Processing
While heat treatment is important in ensuring the safety of apple juice through pasteurisation or sterilisation, for some products heat plays an important role in the production process itself. The physical and chemical properties must be considered when they are juiced and processed. Sugar content is typically around 11%, while dry matters vary between 13 and 20 % depending on variety and ...

Case study - Air-to-air heat exchanger provides plant heat and big savings
OVERVIEW A food processing facility installed a new Regenerative Thermal Oxidizer (RTO) for odor control from its roasting operation. The oxidizer was designed for 95% thermal rate of efficiency and included supplemental fuel injection (SFI) which is used during low VOC loading conditions, to help save fuel cost. The customer was looking at additional ways to further reduce their operating ...

Classification and characteristics of belt dryer
Depending on the flow form of the drying medium, the number of layers of the conveyor belt, and the temperature of the heating medium, the belt dryer can be divided into different types. According to the flow form of the drying medium, it can be divided into a through-flow belt type and a horizontal airflow belt type. According to the number of conveyor belt layers, it can be divided into ...

Multiple uses for heat exchangers in brewing
There are numerous uses for heat exchangers in breweries, from cooling, pasteurising and fermenting products, through to efficiently dealing with waste streams such as yeast slurry. Compared to other methods of heating, heat exchangers can be much more energy efficient, providing both environmental and economic benefits. One of the first uses of heat exchangers in brewing is for rapidly cooling ...

Experts in combustion control - Expert Paper
Fired heaters are integral to hydrocarbon processing (HP). Specifically designed for the reaction of fuel and air to produce extremely high gas temperatures, heaters transfer this energy to potentially highly flammable process fluids via heat exchangers. They consume large quantities of fuel, produce large quantities of emissions and are a potential safety hazard to personnel and plant. However, ...

The Engineering Behind Shell and Tube Heat Exchangers and Their Benefits
Shell and tube heat exchangers are used for the flow of in-line heating and cooling. The innovative design allows the movement of fluids through the tubes and exterior shell delivering changeability. The movement of fluid can be run in a counterflow, cross flow, or parallel mode. The flow of the fluids can not be reversed, so the development of dirty pockets is then eliminated during the ...
