Types of Mixing Tanks
A mixing tank is an important part of a factory’s production process. It allows workers to prepare ingredients quickly and easily for manufacturing. In addition to reducing costs, it also helps ensure quality standards.
Tanks come in several shapes, sizes and styles. Consider the needs of your business and the available space in your facility. Then, determine whether you want the tank to be jacketed or insulated.
Stainless steel
A stainless steel mixing tank is an enclosed container used to blend different types of materials. It can be fabricated from different materials, but stainless steel is the most commonly used material for such tanks because it is durable and corrosion resistant. It is also easy to clean and sanitize, which makes it ideal for sensitive applications.
Stainless steel is a non-reactive material that does not impart any unwanted tastes or odors to the materials it mixes, which can be very important in industries such as food and beverage production. Its hygienic properties make it an ideal choice for sensitive applications such as pasteurization and fermentation. Its smooth surface also prevents bacterial growth, which can reduce the chances of contamination.
When choosing a stainless mix tank, it’s important to consider the contents, size, and temperature of the liquid. Stainless tanks can be insulated and can be heated or cooled to ensure that the liquid remains at the proper temperature. Additionally, stainless tanks are easier to see through than poly ones, which can be a helpful feature for certain applications.
Stainless steel tanks can be cooled using a variety of methods, including immersion chillers and cold water baths. They can also be injected with chilled water mixing tank or coolant directly to the liquid. This method is especially useful when the tank is storing sensitive products such as dairy or pharmaceuticals.
Vertical cylindrical
The vertical cylindrical mixing tank is a versatile plastic container used for chemical storage, food preparation and many other applications. It’s a durable and strong mix tank that is rotationally molded. It has an open top with a fitted cover and can hold a wide range of chemicals. It’s also easy to clean, and the agitator can be removed for cleaning or replacement.
The geometry of the mixing tank’s head can have a major impact on the effectiveness of the mixing process. Sean Donkin of Cleveland Mixer explains that there are four basic geometries of tank heads: flat, dished, sloped, and cone. Each of these designs offers different advantages and disadvantages. Flat bottom tanks have a solid surface that can help with drainage and offer a good balance between strength, draining performance, and axial flow patterns. Dished heads, on the other hand, offer improved drainage and solids suspension performance, but they require a longer shaft, which can increase mixer cost.
When a agitator is mounted on the side of a vertical cylindrical tank without baffles, it creates a swirling pattern that is inefficient and will not mix well with the liquid. In addition, it puts a heavier load on the mixer’s shaft, which requires more powerful mixing equipment. This is especially true when the ratio of liquid height to tank diameter is less than 0.8. In these situations, it is often more cost effective to install baffles on the tank.
Horizontal cylindrical
A horizontal cylindrical mixing tank is designed to facilitate the process of blending different components or substances. It is used in various industries, such as cosmetics and paint production, to ensure consistent blending of liquids and powdered materials. These tanks are also available in a wide range of sizes, and can be made from a variety of materials, such as stainless steel, glass fiber reinforced plastic, and carbon or Kevlar composites.
The design of the mixing vessel is determined by its purpose and the type of product being mixed. In mixing tanks, baffles are required to prevent rotational motion or vortexing of the mixture. Depending on the viscosity of the material, the position of the baffles may vary. Typically, the lower the viscosity of the material, less baffles are needed.
Other design features that influence the mixing performance of horizontal cylindrical tanks include their shape, agitation devices, and mixer mixing tank supplier mounting location. Generally, dished bottom tanks are preferred due to their neutral geometry for drainage and solids suspension performance, but they require a longer mixer shaft than flat bottom tanks.
Safety considerations for mixing tanks primarily revolve around the prevention of spills and leaks. To minimize the risk of these hazards, proper sealing mechanisms and robust construction materials are used to create these vessels. Reactor safety concerns are more complex, and involve preventing the failure of chemical reactions within the reactor itself.
Rectangular
Rectangular mixing tanks can be used in a wide variety of applications, including wastewater treatment and sewage processing. These tanks are often used in conjunction with coagulation and flocculants to remove contaminants from wastewater. In addition, they are also used in the production of high-quality drinking water. Unlike reactors, mixing tanks are typically designed to operate at ambient or slightly elevated temperatures and atmospheric pressure.
The shape of a tank mixer can make or break your mixing application, so it’s important to understand how tank geometry affects mixing. A few missteps in this area could cause your process to fail and result in unnecessary expenses. To avoid these pitfalls, follow these guidelines for selecting the right tank mixer design for your application.
Tanks with a flat base have a wider surface area and offer more efficient drainage than dished bottom tanks. They are also less expensive to fabricate than cylindrical tanks, but they may not be as suitable for solid suspension as a cone-bottom tank. If you’re working with a rectangular tank, you can install baffles to prevent sediment buildup in the corners of the tank.
Cylindrical tanks are prone to “vortexing” when mixed with a centered, vertical agitator. This phenomenon results in a swirling motion that doesn’t mix the liquid properly. To prevent vortexing, you can use baffles or mount the agitator in an eccentric or oblique position. However, these methods only work to a certain extent and can lead to excessive hydraulic loads that damage the shaft of the agitator.
