Food Processing Pages With The Apple Look

My posts on this blog for many years have been written on Apple computers and tablets. I am very much an admirer of Apple and its minimalist approach to design of both hardware and applications. They introduced the clean, light and almost austere look to computer screens which has since become a kind of standard part of succesful user interfaces. So I was struck by the new site of Alfa Laval.

Apple Like Website

To me its really beautiful and very Apple like. However at the same time it has some really good content which I am likely to share in future posts. For example this flowchart of a milk pasteuriser

This flowcharts are interactive linking to father information about the equipment including specifications, diagrams and even animation videos.

As usual I need to note that this information is linked to the equipment of Alfa Laval, which I am not passing any judgement on oe recommending. I do, however, believe that the value of clear information like this outweighs the fact it is linked to the supplier

Ice Pigs in Food Processing?

Talking of pigs in a food processing plant brings to mind an abattoir or a plant in a really sad state of cleanliness. However, this pig is actually behind new operations in Food Processing that improve hygine while saving capacity, chemical, product and water. The principle is explained in this video

I remember first hearing of pipeline pigs when the petroleum pipeline from Durban to Johannesburg was installed. This was basically a rigid plug with the diameter of the pipeline that is pumped through the pipeline between two different fluids. The novelty here is a flexible plug which can even separate fluids in a heat exchanger. The second video demonstrates the process although the transition back to process flow is somewhat spoiled by a demo failure.

While both this videos feature the Food Process Engineering company GEA, this is not to imply they are the only or a preferred supplier. The links below are to other online starting points, but it would be wise to approach your suppliers for further information.

Small Scale Popcorn Equipment

Here is a business that can be set up with quality equipment at an affordable cost.

This is a manual oil kettle based popping plant which can produce 55 kg/h from the two poppers. More poppers can be combined with a larger sifting and cooling table. Poppers can also be combined in automated units.

please note this is not a recommendation, only a sharing of information

High Pressure Processing

I have posted information on High Pressure Processing (HPP) before covering the process, linking to a factsheet and describing a product. HPP is a relatively new process that has advantages in the consumer preference for freshness and health that have been developing recently.


Food safety and quality drive demand for high pressure processing

This article gives a few of the major points found in a recent market investigation.

  • The USA is the leading market for HPP products
  • The East, although an attractive market, has certain constraints based on consumer habits
  • Equipment sales are projected to reach $600 million by 2018
  • Product sales are expected to reach 2,2 billion in the same year
  • Beverages, ready to eat meals, raw proteins and raw pet food have been the successful products to date.

Is this the next big thing in African Food Processing? – I doubt it is likely to become a widely used technology. We still need to catch up with more standard capital intensive technologies as our middle class develops and demands more quality.

However, where we are developing new markets for the indigenous plants of Africa, there is surely an opportunity for HPP to retain flavours and beneficial chemicals tahtt will appeal to wealthy consumers.

This websites covers a range of issue around pumping where positive deplacement pumps can be used. The information is broad ranging from simple description of the different positive deplacement pump technologies, through application notes to a database of liquids and specifications for the pump required to pump them.

Having recently done some examining, in which one of the question was on NPSH and cavitation it was clear that this site's four page pdf would have been very useful.
