• information

A yogurt processing line is a series of equipment and machinery used to produce yogurt in a large-scale production setting. The line typically includes various stages and processes, such as milk reception, milk storage, pasteurization, homogenization, fermentation, cooling, flavoring, filling, packaging, and labeling.

Milk Reception: Raw milk is received and tested for quality before it is stored in designated tanks.

Milk Storage: Milk is stored in temperature-controlled tanks to maintain its freshness and quality.

Pasteurization: The milk is heated to specific temperatures to kill harmful bacteria while preserving beneficial enzymes and nutrients.

Homogenization: The milk is then homogenized to ensure a consistent texture and prevent separation of cream.

Fermentation: The milk is inoculated with live cultures of bacteria (such as Lactobacillus bulgaricus and Streptococcus thermophilus) and incubated at controlled temperatures to allow the fermentation process to occur.

Cooling: Once the desired fermentation time is reached, the yogurt is cooled to stop the fermentation process and stabilize the product.

Flavoring: Flavors, fruits, or other additives are added to the yogurt to enhance taste and texture.

Filling: The yogurt is filled into individual containers, such as cups or bottles, through automated filling machines.

Packaging: The filled containers are then sealed, either by heat-sealing or using lids, and prepared for further processing.

Labeling: The containers are labeled with product information, including nutritional facts, ingredients, and branding.

Quality Control: Throughout the process, quality control measures are implemented to ensure that the yogurt meets the desired standards for taste, texture, and safety.

Storage and Distribution: The packaged yogurt is stored in appropriate conditions before being distributed to retailers or consumers.

Data

Composition of yoghurt fermentation system.

Yoghurt fermentation system includes: online culture addition system, ultra-clean fermentation tanks system, aseptic air system,flexible cooling system and matched pipes, valves,instruments and control programs, etc.

online culture addition system

The online culture addition system adopts the ultra-clean culture online addition method, which includes culture adding tube that
can fit different types of cultures and an aseptic filter air positive pressure protective cover that reaches a 100-level purification level

ultra-clean fermentation tanks system

The ultra-clean fermentation tanks system mainly refers to the fermentation tanks and auxiliary configuration to be used in the yoghurt fermentation process

Flexible cooling system

The flexible cooling system mainly includes a large channel low flow rate plate and a constant temperature water system. Through this system, the fermented yoghurt can be cooled to about 20,and the cooling temperature difference less than 5dT, which can
minimize the damage of the yoghurt viscosity, which can achieve better post-fermentation effect.

Aseptic air system

Aseptic air system includes SUS304 bracket, including degreasing and dewatering filter, activated carbon filter, coarse filter,sterilizing filter, steam filter; compressed air pressure reducing valve, steam pressure reducing valve, pressure gauge,temperature probes, etc., this system can be steam sterilized and CIP cleaned.It is used for the protection of micro positive pressure in the tank during the fermentation process, which can prevent the materials in the tank from being contaminated
by the outside enviroment.

Yogurt Processing Line installation and debugging


The installation and debugging of a yogurt processing line is a complex process that involves several stages to ensure the equipment functions optimally, maintains hygiene standards, and adheres to food safety regulations.



Below is a general guide on how this process typically unfolds:

1. Site Preparation• Clearance and Cleaning: The installation area must be cleared of any debris and thoroughly cleaned before the equipment arrives. This includes sanitizing the floors, walls, and ceiling.• Infrastructure Check: Verify that the site has appropriate water supply, drainage, electricity supply (including voltage compatibility), and ventilation systems in place.

2. Equipment Unloading and Placement• Unpacking: Carefully unpack each piece of equipment, inspecting for any damage during transportation.• Placement: Position the equipment according to the layout plan provided by the manufacturer or engineer. Consider workflow efficiency, ease of maintenance, and accessibility for cleaning when deciding on the placement.

3. Assembly and Installation• Assembly: Follow the manufacturer's instructions to assemble the various parts of the processing line. This may involve connecting tanks, pumps, homogenizers, pasteurizers, fillers, and packaging machines.• Piping and Wiring: Install the necessary pipelines for milk supply, water, steam, and cleaning solutions. Also, wire the electrical components, ensuring all connections are waterproof and conform to safety standards.

4. Calibration and Alignment• Equipment Calibration: Calibrate instruments such as temperature sensors, flow meters, and timers to ensure accuracy.• Alignment: Ensure all machinery is properly aligned to prevent leaks, reduce wear, and promote efficient operation.

5. Utility Connections• Water and Steam: Connect to the water supply and steam generator, making sure all connections are leak-proof.• Refrigeration System: If applicable, connect the cooling system to maintain the required temperatures for fermentation and storage.

6. Sanitization and Sterilization• Cleaning: Thoroughly clean all equipment before use, using appropriate cleaning agents.• Sterilization: Sterilize the entire system to eliminate any potential contaminants, following industry guidelines.

7. Testing and Debugging• Trial Run: Conduct a trial run of the entire processing line without actual product to check for any mechanical or operational issues.• Debugging: Identify and fix any problems encountered during the trial run. This may include adjusting settings, tightening connections, or replacing faulty parts.• Product Testing: Once the system is operating smoothly, conduct a test production run with a small batch of yogurt to assess product quality and taste.

8. Optimization and Training• Process Optimization: Fine-tune the process parameters for maximum efficiency and product quality.• Staff Training: Train the operating staff on the proper usage, cleaning, and maintenance procedures for each piece of equipment.

9. Documentation and Compliance• Documentation: Record all installation, testing, and calibration data for future reference and compliance purposes.• Compliance Check: Ensure the installation adheres to local health and safety regulations, as well as industry-specific standards .
