Butterfly mixing

Types of butterfly mixing

A butterfly mixer is used to mix various types of food products or any mixture with a large volume. In the food industry, they are commonly used to make batter or dough and to mix bulk amounts of ingredients. They are designed for vertical mixing, and the mixing blades are usually shaped like butterflies, made large enough to scoop from the bottom of the bowl to the top. Here are some of the more popular types of butterfly mixers:

• Butterfly Paddle Mixer

  The butterfly paddle mixer is designed for fragile materials that require low mixing speeds. It comprises two symmetrical wings that gently stir the material without damaging it. The wings sweep the material towards the center, properly mixing it. Using this paddle mixer helps achieve a uniform mixture without changing the material's physical properties.

• Butterfly Mixer with Split Disks

  The butterfly mixer with split disks is a common mixing device in the chemical and food production industries. The design includes two disk-shaped wings that create turbulence within the mixture. This turbulence leads to better mixing and diffusion of materials. The butterfly mixer with split disks has benefits like low energy consumption and efficiency in handling delicate materials.

• Reverse Cup Butterflies

  Reverse cup butterflies are mixing elements used in large-scale production processes. They have a unique design resembling inverted cups with open bottoms. The reverse cup butterflies function by lifting and circulating materials in different directions. This movement promotes efficient mixing and blending. One significant benefit of reverse cup butterflies is that they handle large volumes of materials. They contribute to the smooth and uniform mixing of complex ingredients.

• Butterfly Grain Mixers

  Butterfly grain mixers are crucial in moderating the proportions of grains, feed additives, and other components. They offer the advantage of consistent mixing. Butterfly grain mixers are engineered to combine grains precisely with feed additives, flavours, vitamins, minerals, and medicines. The goal is to provide livestock with feed that contains the proper nutrients. By using butterfly grain mixers, livestock can receive feed that is uniformly mixed, ensuring they are adequately nourished.

• Butterfly Mixing Feed Pellet

  The butterfly mixing feed pellet aims to enhance the uniformity of primary ingredients like fish meal, meat and bone meal, and other valuable feed components. It solves the issue of variation in the distribution of essential substances. Moreover, the butterfly mixing feed pellet is designed to cope with the high production demands found in the pelleting industry. These mixers increase productivity by facilitating the fast and efficient blending of feed components before pelleting.

Specification & maintenance of a butterfly mixer

The specifications of a butterfly food mixer will vary depending on the type and size of the machine. Here are some critical parts and their specifications:

• Blade

  The diameter of the butterfly blade ranges from 60 mm to 400 mm, and the angle between the two wings is 15 to 45 degrees. The material used to make the blade is abrasion-resistant food-grade stainless steel.

• motor

  The horsepower of the motor varies from 1 HP to 7.5 HP, depending on the tasks of the mixer. For heavy-duty mixing, a motor with more horsepower will be necessary. The motor can operate at 3450 RPM, 1750 RPM, or variable speed.

• Gearbox

  Mixers with heavy-duty motors have a stronger gearbox. The gearbox has a few crucial parts, such as the shaft, housing, and bearings. The gearbox may have a reduction ratio of 12: 1 or 15: 1.

• Jar

  A butterfly mixer comes with many jars, such as a grinding jar, juicing jar, or food processor jar. The maximum capacity of the grinding jar is about 500 ml. The liquids and food processing jars can mix up to 3- 5 liters of content.

• Control panel

  The control panel will have buttons to turn the mixer on and off. It may also have features like safety locks and speed settings.

Maintenance

A well-maintained butterfly mixer can last many years without unexpected repairs. Here are a few maintenance tips:

• The cleaning routine should start with a thorough cleaning of all jars and blades. First, rinse all parts with warm water. Second, wash the parts with a mild detergent. Third, place parts in a container with a vinegar solution to deodorize and disinfect them.
• Before cleaning the mixer, always check the manual first. The manual will describe the procedure for removing the jars and any other components that require removal for cleaning.
• For deep cleaning, take the mixer to a qualified technician. The technician will service the gearbox, motor, and other critical components.

How to Choose Butterfly Mixing

It's important to recognize that no single approach or method will satisfy every application when selecting a butterfly mixer. The experts suggest that application-specific mixers should be preferred rather than general-use mixers. A general-purpose mixer may do a reasonable job but increase energy consumption and reduce processing efficiency.

It is essential to consider the operation parameters when selecting a butterfly mixing machine. The operation parameters include but are not limited to:

• Viscosity:

  Identifying the average viscosity of the fluids that the mixer will handle is essential. If the mixer is to be used to handle fluids with varying viscosity, one should consider opting for a variable speed mixer to enable it to handle different viscosity levels.

• Temperature:

  The temperature of the fluid to be mixed will determine the type of material that will construct the mixer. A fluid with high temperature may require the mixer's material to have heat resistance to enable it to function optimally.

• Mixing Speed:

  Consideration should be made on the butterfly mixer's speed. This can be affected by factors such as the nature of the fluid to be mixed and the desired outcome. For instance, achieving a fine blending will require a high-speed mixer.

• Seal System:

  The seal system of a butterfly mixing machine helps to prevent any leakage that can occur at the mixing shaft. Leakage can occur due to high pressure, high temperature, and chemical reaction in the environment. Choosing the right seal system will help to minimize maintenance costs and reduce mixing downtime.

It's essential that the mixer selected matches the application's specific needs. A butterfly mixer configured for blending highly viscous liquids will be ill-suited for use in a facility where it's constantly blending low-viscosity liquids. A mixer that is ill-fitted for an application will result in increased energy consumption and reduced processing efficiency.
