The Rademaker industrial Bread production line is designed for medium to large scale industrial bread manufacturers. From tin breads to high water absorption artisan breads and from pre-fermented to 'green' doughs. Flexibility and fast production changeovers are guaranteed thanks to the unique modular design and the various mobile units. Compared to dedicated industrial bread lines, this results in a shorter Return On Investment, that makes the Bread production line the most desired industrial bakery line in the market. The Bread production line is developed to produce a wide variety of bread products for a medium scale bakery to any industrial bakery. Capacities ranging from 500 to 9,000 kg per hour, consistently produced hour by hour, day by day, and year by year.


WORKING WIDTHS


600 mm | 800 mm | 1,000 mm | 1,200 mm


Thorough tests in the Rademaker Technology Center (RTC) are performed in order to determine the exact positive effects of the improved dough homogeneity on the final product weight accuracy. Subsequently the resulting benefits for the Cost Of Ownership are assessed by details calculations based on actual (plant) bakery circumstances.

https://rademaker.com/our-equipment/bread-line


EFFECT ON COST OF OWNERSHIP - The Rademaker industrial Bread production line

Product accuracy can have a significant effect on the overall cost price for production. In general the cost price contribution of the so-called “give away” or product overweight is normally in the range of 20 – 30% of the total added cost of a bread sheeting & make-up line (excluding baking and packing). With the improved accuracy, the added cost of the “give away” portion of the bread sheeting & make-up line can be dramatically reduced. Cost of Ownership (CoO) calculations show that a total cost reduction of up to 15% can be achieved depending on the type of dough. From this investigation it is safe to conclude that the Rademaker industrial Bread line is not only creating a higher quality product but can also seriously boost your profit.

https://books.google.co.in/books?id=c5yMHputGh4C&pg=PA745&lpg=PA745#v=onepage&q&f=false

Handbook of Food Process Design

Jasim Ahmed, Mohammad Shafiur Rahman

John Wiley & Sons, 27-Feb-2012 - Technology & Engineering - 1600 pages

In the 21st Century, processing food is no longer a simple or straightforward matter. Ongoing advances in manufacturing have placed new demands on the design and methodology of food processes. A highly interdisciplinary science, food process design draws upon the principles of chemical and mechanical engineering, microbiology, chemistry, nutrition and economics, and is of central importance to the food industry. Process design is the core of food engineering, and is concerned at its root with taking new concepts in food design and developing them through production and eventual consumption.

Handbook of Food Process Design is a major new 2-volume work aimed at food engineers and the wider food industry. Comprising 46 original chapters written by a host of leading international food scientists, engineers, academics and systems specialists, the book has been developed to be the most comprehensive guide to food process design ever published.

Starting from first principles, the book provides a complete account of food process designs, including heating and cooling, pasteurization, sterilization, refrigeration, drying, crystallization, extrusion, and separation. Mechanical operations including mixing, agitation, size reduction, extraction and leaching processes are fully documented. Novel process designs such as irradiation, high-pressure processing, ultrasound, ohmic heating and pulsed UV-light are also presented. Food packaging processes are considered, and chapters on food quality, safety and commercial imperatives portray the role process design in the broader context of food production and consumption.

How to create a robust bakery supply chain

By Dan Riley19 July 2023


Utilising AI in critical areas such as monitoring raw material quality can help reduce rework and recalls by over 50%, asserts Chand, with savings for larger businesses running into the hundreds of thousands of pounds. Better tech tools can also impress and retain employees, an important consideration for an industry struggling to secure top talent.


According to Chand, digital solutions have enabled TraceGains customers to reduce sourcing and supplier approval time by 50%, and fulfil 75% of resourcing needs. It has also helped increase business by 50% during Covid, improve delivery times and accuracy through cleaner supply chain data, and cut product development time by 75% through digitalisation of aggregated data.


Looking into visibility

As Chand flagged, Joris Kolff, senior director for food & beverage at Aptean also believes data and technology is vital; providing businesses with the tools and insights they need to quickly adapt to a changing marketplace and navigate disruption, improve process efficiency, and offer a holistic view of operations.


This can be achieved through implementation of food-specific software solutions such as Enterprise Resource Planning (ERP), Product Lifecycle Management (PLM) and Manufacturing Execution System (MES), which “close that critical gap” by collating a company’s data into one system.

Energy Industrial Engineering in a Bread Making Company


2021


FLOWERS FOODS: 40-YEAR OLD BAKERY CONVERSION PRIORITIZES ENERGY AND WATER PERFORMANCE

BACKGROUND

Flowers Foods operates 46 bakeries that produce a wide range of products for retail and foodservice customers. Its Lynchburg, Virginia, bakery has been in operation for more than 40 years. To meet the increasing demand for Dave’s Killer Bread (DKB) organic products in the Mid-Atlantic market, Flowers Foods converted Lynch bakery into a state-of-the-art, energy-efficient, sustainable bakery. The Flowers engineering team incorporated many energy and water efficiency technologies into the design of the Lynchburg bakery.  Based on five months of operational data, the production line upgrades are delivering an energy savings of 22.6% and water savings of 64.1%, and the company plans to implement many of the same technologies and practices at its other 46 manufacturing facilities and over 900 warehouses.


The company evaluates energy usage at the start of capital projects to ensure that new production lines not only improve productivity and quality but also deliver significant energy savings. As part of the Lynchburg project, Flowers Foods also took advantage of a performance-based grant through the State of Virginia and received $250,000 to cover the cost of the high-efficiency energy and water technologies installed in the plant.


SOLUTIONS

The Flowers engineering team incorporated many sustainability features into the bakery’s new design, including heat recovery, electric blowers in place of compressed air, a new variable frequency drive (VFD) air compressor for the trimming machine, LED lighting, recycling process improvements, and refrigeration upgrades. 808 lights were replaced with LEDs, and a high efficiency 150 hp VFD-equipped air compressor was installed to replace a less efficient 300 hp fixed speed model. The older chillers were replaced with new high-efficiency chillers and a waste heat recovery system was also implemented to increase energy efficiency and reduce process heating costs.

The heat recovery system is integrated internally into the plant’s catalytic oxidizer emission control system. Waste heat from the oxidizer is recovered to heat hot water for tanks, pipe and tank jackets, and ingredient water. The oxidizer recovery system can generate 0.75 MMBtu/hr. of energy at the source and includes an integrated coil and fin heat exchanger used to recover waste heat from the catalytic oxidizer exhaust. The installation includes custom programmable logic controllers (PLCs) and bypass dampers that regulate the exhaust flow rate through the coil heat exchanger, as well as the amount of heat applied to the coil. With the addition of the heat recovery system, two natural gas-fired boilers were able to be removed.

Other energy and water efficiency measures were integrated into the new cooling and refrigeration systems. These included refrigeration system controls that took advantage of variable flow control sequences using VFDs to reduce pumping system energy use. The new air-cooled chiller system uses significantly less water for cooling as well. In addition, new production processes were implemented to reduce water use. For example, the previous production line used a series of tanks that required regular cleaning. The new production line does not need these additional tanks and they were removed. Lastly, the recycling program was improved by installing a baler on location to improve storage and increase revenue from cardboard recycling. These energy-saving projects decreased the energy intensity by 22.6% from 5.2 MMBtu/ton to 4.0 MMBtu/ton in the first five months of operation. Water use decreased by 64.1% from 389.9 Gal/ton to 140 Gal/ton over this same period.

OTHER BENEFITS

The replacement of old lighting with new LEDs not only saved energy, but also improved lighting levels and reduced heat in the bakery. This improved working conditions in the bakery and reduced HVAC energy use. Due to the success of the energy saving measures implemented at Lynchburg, Flowers Foods’ engineering team will continue to incorporate similar technologies when planning facility upgrades and new production lines across its network. With 46 manufacturing facilities and over 900 warehouses, these best practices will make a significant impact on reducing energy consumption.

Food Engineering Innovations Across the Food Supply Chain

Pablo Juliano, Kai Knoerzer, Jay Sellahewa, Minh H. Nguyen, Roman Buckow

Academic Press, 05-Dec-2021 - Technology & Engineering - 516 pages

Food Engineering Innovations Across the Food Supply Chain discusses the technology advances and innovations into industrial applications to improve supply chain sustainability and food security. The book captures the highlights of the 13th International Congress of Engineering ICEF13 under selected congress themes, including Sustainable Food Systems, Food Security, Advances in Food Process Engineering, Novel Food Processing Technologies, Food Process Systems Engineering and Modeling, among others. Edited by a team of distinguished researchers affiliated to CSIRO, this book is a valuable resource to all involved with the Food Industry and Academia.

Feeding the world’s population with safe, nutritious and affordable foods across the globe using finite resources is a challenge. The population of the world is increasing. There are two opposed sub-populations: those who are more affluent and want to decrease their caloric intake, and those who are malnourished and require more caloric and nutritional intake. For sustainable growth, an increasingly integrated systems approach across the whole supply chain is required.


Focuses on innovation across the food supply chain beyond the traditional food engineering discipline

Brings the integration of on-farm with food factory operations, the inclusion of Industry 4.0 sensing technologies and Internet of Things (IoT) across the food chain to reduce food wastage, water and energy inputs

Makes a full intersection into other science domains (operations research, informatics, agriculture and agronomy, machine learning, artificial intelligence and robotics, intelligent packaging, among others)

Dough Viscoelasticity of the Bread-Making Process Using Dynamic Oscillation Method: A Review


ABSTRACT

Bread quality is an important factor to consider before buying it. The bread makers elaborate on them, and they need parameters of quality to obtain the best product. To evaluate the bread quality, there are some methods used, such as bread volume measurement and texture profile analysis. However, there are rheological studies carried out in dough which give an idea of the quality through viscoelasticity evaluation. Oscillatory dynamic studies are used to define the changes in the chemical components in baking. The objective of this review is to report the viscoelastic effects experienced at each stage of the process due to changes in gluten and starch of the dough using the dynamic oscillation method. For example, the elastic moduli (G′) decrease when the protein is damaged in the mixing, fermentation, and baking. On the other hand, tan δ decreases at high temperatures in the oven due to the starch gelatinization and water evaporation, forming a rigid and porous structure characteristic of the bread.
