Peanut Oil Stock Material Flow Test

Comments Off on Peanut Oil Stock Material Flow Test

Many ingredients used in the food industry have a high oil or moisture content. This can lead to caking, arching, bridging and ratholing. It can also cling to vessel walls, which could lead to spoilage and cross-contamination. AirSweep can resolve these issues quickly and efficiently—as seen in this peanut oil material flow test.

The Setup

Peanuts oil stock was poured into a bin with a 4” diameter discharge. Humidity levels in the plant were 53%.

The AirSweep System

Four AirSweep VA-06 units, placed 90 degrees apart

Challenge

The peanut oil stock was mixed with water, and then packed with a wooden block. Tests showed very sluggish material flow. The bin discharge was completely clogged, and hammering only released a few clumps.

The AirSweep system was switched on. The powerful air nozzles swept the peanut oil back into the flow stream, and in less than 20 seconds, the vessel was completely cleared of material.

Corn Bran Fibre & Corn Germ Meal Material Flow Test

Comments Off on Corn Bran Fibre & Corn Germ Meal Material Flow Test

Food manufacturing plants often deal with powders and bulk materials that have a high tendency of packing, bridging, arching and ratholing. What kind of flow aid can break material blocks and promote first-in/first-out flow, to prevent delays and food spoiling issues?

AirSweep pneumatic flow aids are especially effective for material blocks for problematic flow issues in the food industry—as proven in this Material Flow test for Corn Bran Fiber and Defatted Corn Germ Meal.

Corn Bran / Corn Meal: Applications

Corn bran and defatted corn germ meal are used in many baked goods, processed meats, dairy products, and condiments. It is added as a flour substitute or fat mimetic, or to increase the product’s fiber content. It is often mixed with other flours and milk proteins.

AirSweep USDA-accepted Flow Aids

The AirSweep USDA models are engineered to meet the strict safety and sanitation standards that food plants must follow. The powerful bursts of air break through material blocks and ensure continuous on-demand flow. The nozzles shut close after each pulse to prevent material feedback and contamination.

AirSweep is safe…. and powerful. See it for yourself with the Corn Bran and Corn Meal material flow test. You can also read how AirSweep helped an agribusiness company used the AirSweep to improve their bulk bag filling system.

Recycled Material Flow Test

Comments Off on Recycled Material Flow Test

During the manufacturing process, scrap material that has either been rejected or trimmed off can be collected and sent back to the grinder. Reusing recycled material is good for the environment and the bottom line – but it does pose a material flow challenge.

Any recycled material has a heat history that affects its physical, chemical and flow properties. Bridging, arching, ratholing are common. However, many flow aids are unable to activate this bulk material. Fluidizers do not have the pressure or volume. Vibrators can cause it to settle and compact. Air cannons are too expensive to operate round-the-clock, and the recoil can cause long-term damage to the vessel.

AirSweep can help provide smooth, first-in/first out on-demand flow of all bulk solids, including recycled material. Watch proof of the flow in this video.

Comments Off on Powdered Hydrated Lime Material Flow Test

Hydrated lime is a surprisingly versatile material, used to make both bricks and better tortillas.

Lime is used to make sugar and purify sugar from other sources like maple. It is added to milk to produce butter or convert it into skim milk. It can be added to whey to form calcium lactate, which can be used for other products. Lime is also used to treat waste materials and to manufacture refractory bricks.

AirSweep pneumatic material flow aids are very effective for bulk powders and materials like hydrated lime. Watch the video to see how the AirSweep system can help prevent material blocks and promote on-demand material flow.

Powdered Hemp Material Flow Test

Comments Off on Powdered Hemp Material Flow Test

Hemp is a versatile material that is used in many kinds of commercial and industrial products. The fibers are woven into fabrics that are used for clothes, shoes, bags or furniture. Thicker fibers are used in mulch or animal beddings.

Hemp is also used in the construction industry. Hemp and lime blocks are used for insulation. Hemp walls are also gaining popularity as a “green building material” because they are durable and allow a natural flow of air, thus decreasing energy consumption.

The uses for hemp are growing, but what can keep it flowing? AirSweep is one of the best pneumatic flow aids for bulk materials like hemp. Watch the video to see how the powerful air pulses clear the vessel in seconds.

Gypsum Pebbles Material Flow Test

Comments Off on Gypsum Pebbles Material Flow Test

Gypsum is used in the cement industry as a hardening retarder. It’s also made into dry walls, since its natural moisture content makes it the first line of defense against building fires.

However, gypsum rocks need to broken down before they’re added to other materials. However, like many heavy bulk solids, they can interlock and get stuck in the vessels. This can be very problematic for mineral processing plants that work with tons of material.

This gypsum pebble material flow test shows how the AirSweep system can help prevent material blocks. This set-up uses the AirSweep VA-51, which is ideal for large bins, silos, hoppers, chutes, mixers, and other vessels. You can also read about how AirSweep helped a mineral processing plant improve their productivity by 3000%.

AirSweep is a powerful pneumatic flow aid that can be used for practically any kind of material, vessel and industry. The high pressure, high-volume, 360° bursts of compressed air cut through material blocks and effectively solve ratholing, bridging, arching, caking and other flow issues without damaging the vessels.

This material flow test shows how quickly AirSweep flushes bulk solids like ground oat hulls from a vessel. Increasing the pressure can also speed up the process for fast, reliable, on-demand flow.

Fish Powder Material Flow Test

Comments Off on Fish Powder Material Flow Test

Most flow aids aren’t effective for heavy, moist materials. Rubber fluidizing discs only work for light powders, vibrators can actually pack and condense the material, and hammers and agitators do more damage on the vessel walls. However, this material flow test shows how AirSweep can swiftly and safely solve the problem.

The Setup

Fish meal powder was poured into a vessel with a 4” diameter discharge, in a plant with humidity levels of 40%. The material already showed signs of caking and sticking while it was being handled.

The AirSweep System

Four AirSweep VA-06 units, placed 90 degrees apart

Challenge # 1

We compared the effect of hammering the vessel and using an AirSweep. Hammers only released small clumps. The material plugged the vessel outlet, and there was sticky residue on the vessel walls. AirSweep swept the vessel completely clean in just a few pulses.

Challenge # 2

Water added to the fish meal mixture, turning it into a sticky paste. The AirSweep cleared the bin with less than 10 pulses.
