Here is another example of valuable technology information that is available for free from the FAO.

The manual covers meat science, processing, processing equipment, ingredients and formulations in detail with little mention of other business topics such as distribution, marketing and quality. The book is some 400 pages long is well illustrated with drawings and photographs.
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.
I happened onto this manual just now and it got me to thinking about solar drying again.

The document was prepared as a training manual for a Zimbabwian project funded by the Austrian Embassy titled Establishment of a production, sales and consulting infrastructure for solar thermal plants in Zimbabwe.
Its a comprehensive manual covering many designs and processes which you will see in illustrations from other documents you have read over the years. The 110 page book contains descriptions of many different dryers as well as examples of many different crops and their dryers. It also presents a great deal of technical data on drying but even though the title of the project nothing about markets, packaging and selling.
Solar drying should be all the rage currently giving its potential to impact global food shortage and climate change – but we still seem to be where we were decades ago.
Starting with some background and an explanation of shelf life the 8 page pamphlet goes through building, equipment, legislation, cleaning and sanitation, quality assurance, dairy processes, dairy unit operations, suppliers, references and support organisations.
Even if you are a small dairyman, it would be worth reading this just as another view.
The paper proposes a six stage process and presents a list of items that need to be included in a specification. It also provides some useful links and an example of a purchase specification for a filling machine.
Meat, processes and equipment are described in detail with supporting diagrams and photographs. Processing is described based on the processing principles six classes of meat products defined in the manual and on selected processes. Understanding the difficulty in the hygienic aspects of food processing the manual has a strong focus on Good Hygienic Practices (GHP) and Hazard Analysis and Critical Control Point Schemes (HACCP), which are discussed in detail in the manual. But realizing the complexity of the process it also supplies much background information to allow a good understanding but also describes in practical detail cleaning and sanitation practices.
This appears to really be a very good and comprehensive technology reference manual. It does not address market and business issues.
The paper first defines the need for pasteurisation as being to protect public health and to manage the selflife of dairy products.
It then defines pasteurisation conditions and describes the processes and equipment required to run pasteurisation in a dairy. Heat recovery, pressure drops, holding tube design and instrumentation are discussed in some detail.
As mentioned in a previous post the University of Guelph has a strong reputation in Food Technology and has some very useful online information. Its worth following the link from the image and browsing around to see what other useful information you can find.
