A Guide To Powder Handling Solutions for the Food Industry

Powder handling solutions for the food industry impact product quality, integrity, safety, and efficiency. Proper handling leads to uniform mixing, prevents contamination, and maintains hygiene standards. Further, it minimises waste and optimises production processes.

Moreover, careful handling aids in maintaining the flavour, texture, and nutritional value of food products. As the quality standards and regulations are becoming more stringent, effective powder handling solutions must comply with changing safety standards. This will foster consumer trust and brand integrity in a competitive market.

In this blog, we will study powder handling in food production and go through the challenges, quality control and solutions in depth.

A] Common Challenges In Food Powder Handling 

Managing powders in the food industry comes with several challenges. Manufacturers notice difficulty in maintaining consistency as well as moisture and contamination issues. As a result, they prefer pneumatic conveying for powder handling.

1. Consistency

Food powders need to achieve uniformity in terms of particle size. It is important for optimal mixing and food powder processing. If you notice uncertainty in consistency, it can lead to uneven texture and flavour. Further, it will affect consumer satisfaction by degrading product quality.

2. Moisture

It should be noted that food powders are highly sensitive to moisture. Moisture can cause clumping, caking, or spoilage. Excessive amounts of moisture will affect the flowability of the powder, which will be difficult to handle and process.

3. Cross-Contamination

One of the major concerns in the food industry is cross-contamination. When the product has multiple ingredients, the risk of contamination increases. The presence of trace amounts of allergens can even compromise product safety.

B] Importance Of Quality Control 

Quality control is a major aspect of the food sector. It ensures good quality and safe food production. Having a proper QA/QC mechanism will increase the sales rate. It is essential to maintain the current and future demand.

Pneumatic conveyors for the food industry play a crucial role in maintaining the quality and integrity of food products. They take care of the quality throughout the manufacturing process. Maintaining quality results in uniformity in texture and consistency. It ensures each batch of food products receives high quality and proper texture.

Moreover, it preserves the nutritional content, value and taste of the food products. Hence, with the use of advanced powder-handling equipment processing equipment, you can better handle sensitive food materials under optimal conditions, leading to cost savings and improved profitability.

C] What Type Of Powder Handling Solutions Work The Best? 

1. Dilute Phase Pneumatic Conveying

A dilute phase conveying system is also known as a lean phase conveying system. This conveying process is described as the way of vacuum pulling or pressure pushing of the particles that are suspended in air from one place to another. By using high velocity and low pressure, the air-suspended particles are continuously transferred.

Do you want to know how this pneumatic conveying process works? In this process, high-velocity air is employed in the system to suspend and transfer food particles through pipes. The system works seamlessly with grains and light powders. Dilute phase pneumatic conveying systems are considered an economical option for food processing due to their powder conveying systems benefits and energy efficiency.

2. Dense Phase Pneumatic Conveying

A dense phase pneumatic conveying system works in a process where food powders are conveyed in batches with the help of higher pressure and lower air velocities. In this process, food materials are transferred in bulk via an enclosed pipeline.

In general, the velocity of air used is up to 3-14m/s. The system works by slowly conveying powder, which makes it a material-friendly option. Higher air pressure with a low-velocity rate is utilised in the dense phase conveying system to transport materials in a non-suspended form.

The dense phase pneumatic conveying system is an ideal solution to move food products that are scratchy or delicate. This system reduces product deterioration and preserves food quality during transportation.

3. Vacuum Conveying

The process of moving bulk powder materials in a food production factory using suction is known as Vacuum Conveying. The interesting part of this process is it uses the principle of negative pressure and air velocity to transport materials via an enclosed pipe network. It is widely popular in several production applications in the landscape of industrial manufacturing.

Here are the details of their working mechanism: The food powder materials are transferred in a tubing network from the source or pick-up point to the end process. Most vacuum conveying systems transfer products to the vacuum receiver at predetermined time intervals. This makes the process more convenient and easier.

This conveying system generates a negative pressure atmosphere to materials more softly. It precisely handles transferring and recognises high product quality assurance.

4. Positive Pressure Pneumatic Conveying

In a positive-pressure pneumatic conveying system, compressed air is used to push materials down the pipeline during its transport. It is an ideal solution for transferring cohesive powders and irregularly shaped particles.

Positive pressure dilute phase pneumatic conveying systems are commonly utilised to move bulk powder materials from a single source to one or multiple destinations smoothly. The system supports longer distances and higher capacities than vacuum systems.

This specific system uses a positive displacement blower that has either a single or multiple downstream entry points. Each entry point metres product into the conveying lines using a rotary airlock valve, which maintains the pressure differential between the ambient environment and the conveying line.
