Farmer Invests $15 Million in Dairy Equipment

Here is a really inspiring story of a small producer investing in a state of the art technology and getting support from the Industry – it should give us all the faith to tackle what seems out of reach.


Food Stuff SA brings you news on the latest Food Trends - Homsek delivers the dairy difference.jpg

Basically Anton Homsec has built a dairy farm over the last eight years that now produces 20 000l and buys in 80 000 litres per day to feed his dairy that includes his latest investment in a state of the art aseptic bottle packaging plant.

The growth is based on a 2001 contract Anton secured from Woolworths, South Africa’s high end food retailer. The contract was based on a herd of Ayrshire cows that are raised and maintained without the use of any hormones. The successful marketing of this product put Homsec in the position to be able to invest R150-million in a totally new aseptic milk format for the South African market, an HDPE bottle.

Woolworths agreed to change to a bottle based system because

The international long-life milk trend is definitely in favour of plastic. The layered bottle is ideally suited to optimal UV protection, it’s recyclable, there are many decoration options and the bottles can be any shape or design. They’re also easy to open, reclose and handle; and also relatively inexpensive to produce.

The story details the suppliers of equipment and bottles and how they supported Homsec in the installation and commissioning of the plant in a farm area 20 km north of Bloemfontein.


Food & Process Engineering Technology – Free Online Information

I, as a chemical engineer, am really excited to find a book like this on line and easily usable.

The book is on SCRIBD which has been called the youtube of documents. Although posters on SCRIBD can make their posts downloadable this one does not, so you can only stream it.

The clip below tries, but fails, to show the blend between quantitativeness and practicality.

Rather, if you are interested in Food Processing and brining comprehensive calculation into it go and see the book.

The Chapters are titled.

    • Problem Solving Tools: Dimensions and Units, Algebraic Equations, Graphs and Coordinate Systems
    • Mass and Energy Balances: Conservation of Mass, Conservation of Energy
    • Physical Properties of Food and Biological Materials
    • Textural Properties of Food and Biological Materials
    • Fluid Flow: Fluid Characteristics, Fluid Statics, Fluid Energy Balance (Bernoulli Equation), Fluid Friction Loss, Pumps and Fans, Non-newtonian Fluids
    • Heat Transfer: Conduction, Convection, Radiation, Heat Exchangers, Thermal Properties
    • Thermal Processing
    • Psychrometrics
    • Drying and Dehydration: Equilibrium Moisture Concepts, Drying Theory and Models, Drying Applications
    • Refrigeration: Equipment sizing, Refrigeration load, cooling time
    • Biological Product Preservation: Deteriorative Mechanisms, Storage Fundamentals, Thermal Sterilization and Preservation

I am not sure how this book is able to appear online, but since its there why not have a look! Either click the clip above to open in your browser or click below to stream here.

How To Brew Beer According To GEA

GEA the multination food and brewing equipment company has a sophisticated presentation of how beer is brewed.

The presentation consists of 17 pages which represent Unit Operations in the brewing process. Each page has short and simple text explaining the process, clickable animations of processes, photographs of real equipment, links to suppliers and often a link to related expanded information.

The presentation is controlled through forward and backward links or a flowsheet like summary of the brewing process.

Although this is of course a tool to advertise GEA and its business it is informative and gives a view of the state of the art in brewing.


South Africa – Apple Orphans?

I have often complained about Apple, iTunes and the App Store in South Africa.

We pay more for our iPhone and get practically nothing! We are unable to communicate easily with Apple and it seems like the local representatives are not much better informed.

This clip of the countdown to 1 billion apps downloads really illustrates the point well, at least on the App Store side!

clip from South African app store



Yes that’s right the most downloaded free application in South Africa is bubblewrap! and Powerboat Challenge the most downloaded paid app. Not because of the limit of our dexterity or intellect but because we do not have a games category in the App Store!

Please Apple!


We also don’t have any other iTunes content – only the crippled app store and the 8GB 3G iPhone costs US$ 540! I sometimes wonder why they manage to sell!


International Food Science & Technology Congress – SA 2010

Organic Food Sales Slump – What of Other High Cost Trendies?

As this Blog said but some people tried not to see, the sales of organic foods have slumped drastically in the UK, falling a fifth in a year.

Actually this was inevitable but the question it raises is what of the other trends in the Food Industry that cost extra such as

    • convenience foods
    • nutriceuticals
    • ethical foods such as FAIRTRADE
