The Journey from Egg to Powder: A Detailed Manufacturing Process by Aksh Engineering
The transformation of liquid eggs into shelf-stable powder is a multi-step, technologically advanced process designed by Aksh Engineering to preserve nutritional value and functional properties while ensuring paramount food safety and regulatory compliance.
- Egg Reception and Storage:
- Fresh shell eggs are delivered to Aksh Engineering's designed plant and immediately subjected to rigorous quality checks for integrity and cleanliness.
- They are then carefully transferred to controlled-environment storage rooms (typically 4-7°C) to maintain freshness and prevent microbial growth until processing. Aksh Engineering provides guidance on optimal storage solutions to ensure raw material quality.
- Washing and Sanitization:
- Before breaking, eggs are thoroughly washed and sanitized using automated egg washers supplied and integrated by Aksh Engineering. These systems remove dirt, debris, and surface bacteria, minimizing the risk of contamination during breaking. Food-grade sanitizers are often used in this step, followed by a clean water rinse.
- Egg Breaking and Separation:
- This is a critical step performed by highly efficient, automated egg breaking machines. Aksh Engineering integrates robust and hygienic egg breakers that can process thousands of eggs per hour, separating the yolk from the albumen with minimal cross-contamination. Their designs prioritize gentle handling to maximize liquid yield and minimize shell fragments.
- For whole egg powder, separation is not required. For yolk and albumen powder, precision separation is paramount, achieved by specialized centrifugal separators integrated into the Aksh Engineering line.
- The liquid egg products (whole egg, yolk, or albumen) are collected in separate hygienic, stainless steel holding tanks supplied by Aksh Engineering, ready for the next stage.
- Filtration:
- The liquid egg is precisely pumped through fine, sanitary filters integrated by Aksh Engineering to remove any shell fragments, chalaza, or membrane pieces, ensuring a smooth, homogeneous, and clean product. This critical step prevents potential damage to downstream equipment and enhances final product quality.
- Standardization (Optional but Recommended by Aksh Engineering):
- For consistency in the final product's functional properties and solids content, the liquid egg might be standardized. Aksh Engineering can provide mixing tanks and control systems to precisely adjust the solids content or other parameters to a specific level, particularly important for achieving desired functional attributes in the final powder.
- Pasteurization:
- This is a crucial food safety step. Aksh Engineering integrates highly efficient Plate Heat Exchangers for pasteurization. The liquid egg is rapidly heated to a specific temperature (e.g., 60-65°C for whole egg, 55-57°C for albumen) and held for a short, precisely controlled duration (e.g., 2-3 minutes) to kill pathogenic bacteria, particularly Salmonella, without denaturing the proteins excessively.
- Different pasteurization parameters are critical for whole egg, yolk, and albumen due to their varying heat sensitivities, and Aksh Engineering's control systems ensure accurate parameter adherence. Rapid cooling immediately follows pasteurization, often using a regenerative section within the plate heat exchanger for energy efficiency.
- Desugaring (for Egg White Powder, a specialized Aksh Engineering capability):
- Egg white naturally contains glucose, which can lead to undesirable browning (Maillard reaction), off-flavors, and reduced solubility during drying and storage.
- For egg albumen powder, a desugaring step is essential. Aksh Engineering designs and integrates controlled fermentation systems (using specialized tanks, agitators, and aeration systems) that employ either controlled yeast fermentation or enzymatic treatment (glucose oxidase) to convert glucose. This process is meticulously controlled to ensure optimal sugar removal while preserving the critical foaming properties of the egg white.
- Drying: The Core of Aksh Engineering's Egg Powder Plant
- This is the central process where moisture is removed to achieve shelf stability. Spray drying is the predominant method due to its efficiency, speed, and ability to produce a fine, uniform powder with preserved functional properties. Aksh Engineering's deep expertise in spray drying is a cornerstone of their egg powder plants.
- Aksh Engineering's Spray Drying Process: The pasteurized liquid egg (and desugared, if albumen) is atomized into a fine mist inside a large drying chamber, designed by Aksh Engineering for optimal airflow and hygiene. Hot air (ranging from 150°C to 200°C, depending on the product and type of egg powder) is simultaneously introduced, causing rapid evaporation of water from the droplets. The rapid drying minimizes heat degradation, preserving the functional properties and nutritional value. Aksh Engineering customizes the drying chamber dimensions, atomizer selection (Nozzle or Rotary), and airflow patterns to suit the specific egg product.
- Anti-Sticking Design: Egg powder can be highly sticky. Aksh Engineering's spray dryers incorporate advanced anti-wall deposition systems such as pneumatic wall sweepers, vibrators, or precisely designed air brooms to prevent product buildup on the chamber walls. This ensures continuous operation, maximizes yield, and facilitates quick, thorough cleaning.
- Gentle Drying Parameters: Aksh Engineering meticulously calibrates the inlet and outlet air temperatures, and atomization parameters, to ensure the product experiences an extremely short residence time at a relatively low temperature (due to evaporative cooling), protecting the delicate egg proteins.
- Cooling and Agglomeration (Optional, Offered by Aksh Engineering):
- The hot egg powder from the spray dryer is rapidly cooled to ambient temperature to prevent caking, extend shelf life, and ensure optimal flowability for packaging. Aksh Engineering can integrate Vibratory Fluid Bed Coolers for this purpose.
- Sometimes, especially for instantized products (e.g., instant omelet mixes, beverage bases), the powder undergoes agglomeration. This process, often performed in a multi-stage spray dryer or an integrated fluid bed, creates larger, porous particles that dissolve more readily in water, improving handling and user convenience. Aksh Engineering offers these advanced drying solutions when desired.
- Milling and Sieving (if necessary):
- The dried powder may be milled to achieve a uniform particle size and remove any lumps that formed. Aksh Engineering integrates sanitary milling equipment when required. Sieving further ensures consistency and removes any larger aggregates, ensuring final product quality.
- Packaging:
- The final egg powder is typically packed in multi-layered, moisture-proof bags (e.g., Kraft paper bags with polyethylene liners), drums, or bulk containers. Packaging is done in a controlled atmosphere to prevent moisture absorption and oxidation. Nitrogen flushing is often used by Aksh Engineering's integrated packaging solutions for extended shelf life.
- Storage:
- Packaged egg powder is stored in cool, dry conditions, preferably at temperatures below 20°C, to maintain quality and extend shelf life, which can range from 12 to 24 months or even longer depending on the type and packaging.
