Importance of Proper Drainage in Food Processing Equipment

Drain sanitation is a crucial aspect of food processing equipment. Proper drainage ensures that food products are not contaminated, which can lead to illnesses and other health issues. In this blog post, we will discuss the importance of proper drainage in food processing equipment and how it can prevent contamination and protect the safety of […]

Positive and Negative Displacement

In fluid mechanics, displacement refers to the movement of a fluid within a system or container. This movement can either be positive or negative, depending on the direction in which the fluid is moving. Positive Displacement Positive displacement occurs when a fluid is pushed or moved in a specific direction, such as when it is […]

Types of Elastomer Choices

Elastomers are a type of polymer material that are known for their ability to stretch and return to their original shape. This property, known as elasticity, makes elastomers useful in a wide range of applications, from automotive parts to medical devices. There are several different types of elastomers available, each with its own unique properties […]

The Advantages of Butterfly Valves: Fast, Efficient Flow Control

The Advantages of Butterfly Valves Butterfly valves are quarter-turn, rotary valves that are used in various industries to control the flow of fluids. These valves are named after their distinctive disc-shaped closing mechanism, which is shaped like a butterfly’s wings. Butterfly valves are known for their simple and compact design, making them an ideal choice […]

What is Cleaning out of Place (COP)? How does it differ from Cleaning in Place (CIP)?

Cleaning out of place (COP) and cleaning in place (CIP) are two common methods used to clean industrial equipment and machinery. While these methods may seem similar at first glance, there are actually some important differences between the two. In this blog post, we will explore what COP and CIP are, how they differ, and […]

What is Line Shock?

Line shock is a condition that affects electric utility workers who are working on power lines. It occurs when a worker comes into contact with a live electrical wire, causing a potentially dangerous or even fatal electric shock. Line shock is a serious concern for electric utility workers, as it can cause severe burns, muscle […]

Sanitary Check Valves

A spring check valve is a type of valve that prevents the flow of liquid in a pipe. It can be used to close a process line by regulating the closing pressure. This type of valve uses a spring to exert pressure against the valve’s seat to stop the flow of fluids. The spring then […]

What Causes Pump Cavitation?

Cavitation in a fluid is a phenomenon that occurs when air bubbles in a solution suddenly collapse. This happens because the pressure inside the pump changes, which then creates shock waves. These shock waves cause the components of the solution to get eroded. When the net positive suction head is lower than the net positive […]

Overview of Process Instrumentation

Digital instruments are more complex than their analog counterparts. They rely on the conversion of the data into an electrical signal, which can be viewed on a monitor or other device. Depending on the type of instrument and its operation, digital flow meters can be categorized into various types. Some of these include devices that […]

What is CIP Cleaning?

CIP cleaning is a process utilized for cleaning the interior surfaces of various food and beverage equipment, including tanks, pumps, and homogenizers. This cleaning process is usually carried out using an automated CIP system. However, instead of cleaning the equipment, parts that cannot be cleaned-in-place are often cleaned-out-of-place. This method involves removing components such as […]

4 Types of Heat Exchangers and Applications

Have you ever been driving down the highway and seen smoke drifting up from a smokestack? The truth is, all that smoke is wasted energy that could be used for another purpose. That’s why heat exchangers exist. A heat exchanger allows the heat from a fluid (liquid or gas) to pass through a second fluid […]

3 Types of Homogenizers and Applications

A homogenizer is used in various industrial and laboratory settings to homogenize various types of materials. Many different models are available for different applications. There are many different names for the same equipment. homogenization is done by removing the organelles from the cell. This step is typically performed prior to the analysis of various biological […]

Centrifugal Pumps: Go with the Flow

Centrifugal pumps are used for transporting liquids or fluids. They are sub-class of turbomachinery that convert kinetic energy into hydrodynamic energy. The rotational energy that a pump produces comes from an engine or a turbine. In most cases, the fluid enters the pump along its rotating axis and flows radially outward. This is the reverse […]

What is a Plate Heat Exchanger?

Plate heat exchangers are used for transferring heat between two fluids. They work by covering the fluids with metal plates. This feature helps in the transfer of heat and provides a high temperature response. Plate heat exchangers are commonly used in combination boilers. The high heat transfer efficiency of a small plate heat exchanger has […]

What is a Shell and Tube Heat Exchanger?

A shell and tube heat exchanger is a type of heat exchanger that works by having a set of tubes inside a vessel that’s designed to collect and transfer heat between two fluids. Both the shell and the tubes are designed to work together to provide heat. Application Two fluids, which are separated by their […]

What is a Double Tube Heat Exchanger?

Heat exchangers are devices that transfer heat between two streams of liquid or gas without mixing them. They are known to work by creating a gap between the streams and a physical barrier. A double pipe heat exchanger is a type of heat exchanger that works by using two pipes to carry out its work. […]

What is Vat Pasteurization?

Vat pasteurization, also known as batch pasteurization or the holding method, heats every particle of milk or cream in properly designed and operated equipment, at 145°F (63°C) for 30 minutes*. If the fat content of the milk product is 10 percent or greater, or a total solids of 18% or greater, or if it contains […]
